In particular, there are several variables you can set that modify the behavior of leap. For example: - - @platform_directory_path = '../leap_platform' - @log = '/var/log/leap.log' - -Additionally, you can create a `~/.leaprc` file that is loaded after `Leapfile` and is evaluated the same way. - -Platform options: - -* `@platform_directory_path` (required). This must be set to the path where `leap_platform` lives. The path may be relative. - -Vagrant options: - -* `@vagrant_provider`. Changes the default vagrant provider ("virtualbox"). For example, `@vagrant_provider = "libvirt"`. -* `@vagrant_network`. Allows you to override the default network used for local nodes. It should include a netmask like `@vagrant_network = '10.0.0.0/24'`. -* `@custom_vagrant_vm_line`. Insert arbitrary text into the auto-generated Vagrantfile. For example, `@custom_vagrant_vm_line = "config.vm.boot_mode = :gui"`. -* `@vagrant_basebox` allows specifying a different basebox as the default one. For example, `@vagrant_basebox = "LEAP/jessie"`. - -Logging options: - -* `@log`. If set, all command invocation and results are logged to the specified file. This is the same as the switch `--log FILE`, except that the command line switch will override the value in the Leapfile. - - -JSON format -------------------------------------------- - -All configuration files, other than `Leapfile`, are in the JSON format. For example: - - { - "key1": "value1", - "key2": "value2" - } - -Keys should match `/[a-z0-9_]/` and must be in double quotes. - -Unlike traditional JSON, comments are allowed. If the first non-whitespace characters are `//` then the line is treated as a comment. - - // this is a comment - { - // this is a comment - "key": "value" // this is an error - } - -Options in the configuration files might be nested hashes, arrays, numbers, strings, or boolean. Numbers and boolean values should **not** be quoted. For example: - - { - "openvpn": { - "ip_address": "1.1.1.1", - "protocols": ["tcp", "udp"], - "ports": [80, 53], - "options": { - "public_ip": false, - "adblock": true - } - } - } - -If the value string is prefixed with an '=' character, the result is evaluated as ruby. For example: - - { - "domain": { - "public": "domain.org" - } - "api_domain": "= 'api.' + domain.public" - } - -In this case, the property "api_domain" will be set to "api.domain.org". So long as you do not create unresolvable circular dependencies, you can reference other properties in evaluated ruby that are themselves evaluated ruby. - -See "Macros" below for information on the special macros available to the evaluated ruby. - -TIP: In rare cases, you might want to force the evaluation of a value to happen in a later pass after most of the other properties have been evaluated. To do this, prefix the value string with "=>" instead of "=". - -Node inheritance ----------------------------------------- - -Every node inherits from common.json and also any of the services or tags attached to the node. Additionally, the `leap_platform` contains a directory `provider_base` that defines the default values for tags, services and common.json. - -Suppose you have a node configuration for `bitmask/nodes/willamette.json` like so: - - { - "services": "webapp", - "tags": ["production", "northwest-us"], - "ip_address": "1.1.1.1" - } - -This node will have hostname "willamette" and it will inherit from the following files (in this order): - -1. common.json - - load defaults: `provider_base/common.json` - - load provider: `bitmask/common.json` -2. service "webapp" - - load defaults: `provider_base/services/webapp.json` - - load provider: `bitmask/services/webapp.json` -3. tag "production" - - load defaults: `provider_base/tags/production.json` - - load provider: `bitmask/tags/production.json` -4. tag "northwest-us" - - load: `bitmask/tags/northwest-us.json` -5. finally, load node "willamette" - - load: `bitmask/nodes/willamette.json` - -The `provider_base` directory is under the `leap_platform` specified in the file `Leapfile`. - -To see all the variables a node has inherited, you could run `leap inspect willamette`. - -### Inheritance rules - -Suppose you have a node configuration `mynode.json`: - - { - "tags": "production", - "simple_value": 100, - "replaced_array": ["dolphin", "kangaroo"], - "+add_array": ["red", "black"], - "-subtract_array": ["bitter"], - "converted_to_array": "not_array_element", - "!override": ["insist on this value"], - "hash": { - "key1": 1, - "key2": 2 - } - } - -And a file `tags/production.json`: - - { - "simple_value": 99999, - "replaced_array": ["zebra"], - "add_array": ["green], - "subtract_array": ["bitter", "sweet", "salty"], - "converted_to_array": ["array_element"], - "override": "this value will be overridden", - "hash": { - "key1": "one" - } - } - -In this scenario, `mynode.json` will inherit from `production.json`. The output of this inheritance will be: - - { - "tags": "production", - "simple_value": 100, - "replaced_array": ["dolphin", "kangaroo"], - "add_array": ["red", "black", "green"], - "subtract_array": ["sweet", "salty"], - "converted_to_array": ["not_array_element", "array_element"], - "override": ["insist on this value"], - "hash": { - "key1": 1, - "key2": 2 - } - -The rules for inheritance (where 'old' refers to the parent, and 'new' refers to the child): - -* Simple values (strings, numbers, boolean): - * Replace the old value with the new value. -* Array values: - * Two arrays: replace the old array with the new array. - * One array and one simple value: add the simple value to the array. - * If property name is prefixed with "+": merge the old and new arrays. - * If property name is prefixed with "-": subtract new array from old array. -* Hash values: - * Hashes are always merged (the result includes the keys of both hashes). If there is a key in common, the new one overrides the old one. -* Mismatch: - * Although you can mix arrays and simple values, you cannot mix arrays with hashes or hashes with simple values. If you attempt to do so, it will fail to compile and give you an error message. -* Override: - * If property name is prefixed with "!": then ensure that new value is always used, regardless of old value. In this case, the override takes precedence over type checking, so you will never get a type mismatch. - -NOTE: special property name prefixes, like "+", "-", or "!", are not included in the property name. These prefixes determine the merge strategy, but are stripped out when compiling the resulting JSON file. - -Common configuration options ----------------------------------------- - -You can use the command `leap inspect` to see what options are available for a provider, node, service, or tag configuration. For example: - -* `leap inspect common` -- show the options inherited by all nodes. -* `leap inspect --base common` -- show the common.json from `provider_base` without the local `common.json` inheritance applied. -* `leap inspect webapp` -- show all the options available for the service `webapp`. - -Here are some of the more important options you should be aware of: - -* `ip_address` -- Required for all nodes, no default. -* `ssh.port` -- The SSH port you want the node's OpenSSH server to bind to. This is also the default when trying to connect to a node, but if the node currently has OpenSSH running on a different port then run deploy with `--port` to override the `ssh.port` configuration value. -* `mosh.enabled` -- If set to `true`, then mosh will be installed on the server. The default is `false`. - -Macros ----------------------------------------- - -When using evaluated ruby in a JSON configuration file, there are several special macros that are available. These are evaluated in the context of a node (available as the variable `self`). - -The following methods are available to the evaluated ruby: - -`variable.variable` - - > Any variable defined or inherited by a particular node configuration is available by just referencing it using either hash notation or object field notation (e.g. `['domain']['public']` or `domain.public`). Circular references are not allowed, but otherwise it is OK to nest evaluated values in other evaluated values. If a value has not been defined, the hash notation will return nil but the field notation will raise an exception. Properties of services, tags, and the global provider can all be referenced the same way. For example, `global.services['openvpn'].x509.dh`. - -`nodes` - - > A hash of all nodes. This list can be filtered. - -`nodes_like_me` - - > A hash of nodes that have the same deployment tags as the current node (e.g. 'production' or 'local'). - -`global.services` - - > A hash of all services, e.g. `global.services['openvpn']` would return the "openvpn" service. - -`global.tags` - - > A hash of all tags, e.g. `global.tags['production']` would return the "production" tag. - - `global.provider` - - > Can be used to access variables defined in `provider.json`, e.g. `global.provider.contacts.default`. - -`file(filename)` - - > Inserts the full contents of the file. If the file is an erb template, it is rendered. The filename can either be one of the pre-defined file symbols, or it can be a path relative to the "files" directory in your provider instance. E.g, `file :ca_cert` or `files 'ca/ca.crt'`. - -`file_path(filename)` - - > Ensures that the file will get rsynced to the node as an individual file. The value returned by `file_path` is the full path where this file will ultimately live when deploy to the node. e.g. `file_path :ca_cert` or `file_path 'branding/images/logo.png'`. - -`secret(:symbol)` - - > Returns the value of a secret in secrets.json (or creates it if necessary). E.g. `secret :couch_admin_password` - -`hosts_file` - - > Returns a data structure that puppet will use to generate /etc/hosts. Care is taken to use the local IP of other hosts when needed. - -`known_hosts_file` - - > Returns the lines needed in a SSH `known_hosts` file. - -`stunnel_client(node_list, port, options={})` - - > Returns a stunnel configuration data structure for the client side. Argument `node_list` is an `ObjectList` of nodes running stunnel servers.

Once everything works and you are comfortable with your LEAP-powered infrastructure, you can then contemplate integrating with your existing domain. - -### Definitions - -**provider domain** - -This is the main domain used to identify the provider. The **provider domain** is what the user enters in the Bitmask client. e.g. `example.org`. The full host name of every node in your provider infrastructure will use the **provider domain** (e.g. `dbnode.example.org`). - -In order for the Bitmask client to get configured for use with a provider, it must be able to find the `provider.json` bootstrap file at the root of the **provider domain**. This is not needed if the Bitmask client is "pre-seeded" with the provider's information (these providers show up in a the initial list of available providers). - -**webapp domain** - -This is the domain that runs the leap_web application that allows users to register accounts, create help tickets, etc. e.g. `example.org` or `user.example.org`.

Typically, this is set automatically and you never need to configure it. The user should never be aware of this domain. e.g. `api.example.org`. The Bitmask client discovers this API domain by reading it from the `provider.json` file it grabs from the **provider domain**. - -**mail domain** - -This is the domain used for mail accounts, e.g. `username@example.org`. Currently, this is always the **provider domain**, but it may be independently configurable in the future. - -Generating a zone file ------------------------------------ - -Currently, the platform does not include a dedicated `dns` service type, so you need to have your own setup for DNS. You can generate the appropriate configuration options with this command: - - leap compile zone - -A single domain -------------------------------- - -The easy approach is to use a single domain for **provider domain**, **webapp domain**, and **email domain**. This will install the webapp on the **provider domain**, which means that this domain must be a new one that you are not currently using for anything. - -To configure a single domain, just set the domain in `provider.json`: - - { - "domain": "example.org" - } - -If you have multiple environments, you can specify a different **provider domain** for each environment.

This is needed if you already have a website running at your **provider domain**. - -In order to put webapp on a different domain, you must take two steps: - -1. You must configure `webapp.domain` for nodes with the `webapp` service. -2.

In the example above, there is an environment called "production" and one called "staging", but your setup will probably differ. - -The resulting `provider.json` file must then be put at the root URL of your **provider domain** for the appropriate environment. - -There is one additional complication: currently, the Bitmask client tests for compatibility using some HTTP headers on the `/provider.json` response. This is will hopefully change in the future, but for now you need to ensure the right headers are set in the response. The included file `htaccess` has example directives for Apache, if that is what you use. - -This step can be skipped if you happen to use the `static` service to deploy an `amber` powered static website to **provider domain**. In this case, the correct `provider.json` will be automatically put into place. - -Integrating with existing email system ------------------------------------------ - -If your **mail domain** already has users from a legacy email system, then things get a bit complicated. In order to be able to support both LEAP-powered email and legacy email on the same domain, you need to follow these steps: - -1. Modify the LEAP webapp so that it does not create users with the same name as users in the legacy system. -2. Configure your legacy MX servers to forward mail that they cannot handle to the LEAP MX servers, or vice versa. - -### Step 1. Modify LEAP webapp - -In order to modify the webapp to respect the usernames already reserved by your legacy system, you need to modify the LEAP webapp code. The easiest way to do this is to create a custom gem that modifies the behavior of the webapp. - -For this example, we will call our custom gem `reserve_usernames`. - -This gem can live in one of two places: - -(1) You can fork the project leap_web and put the gem in `leap_web/vendor/gems/reserve_usernames`. Then, modify `Gemfile` and add the line `gem 'common_languages', :path => 'vendor/gems/reserve_usernames'` - -(2) Alternately, you can put the gem in the local provider directory `files/webapp/gems/reserve_username`. This will get synced to the webapp servers when you deploy and put in `/srv/leap/webapp/config/customization` where it will get automatically loaded by the webapp. - -What should the gem `reserve_usernames` look like? There is an example available here: https://leap.se/git/reserved_usernames.git - -This example gem uses ActiveResource to communicate with a remote REST API for creating and checking username reservations.

However, if you are curious as to what is going on, here is a quick primer. - -First, some background terminology: - -* **puppet**: Puppet is a system for automating deployment and management of servers (called nodes). -* **hiera files**: In puppet, you can use something called a 'hiera file' to seed a node with a few configuration values. In LEAP, we go all out and put *every* configuration value needed for a node in the hiera file, and automatically compile a custom hiera file for each node. - -When you run `leap deploy`, a bunch of things happen, in this order: - -1. **Compile hiera files**: The hiera configuration file for each node is compiled in YAML format and saved in the directory `hiera`. The source material for this hiera file consists of all the JSON configuration files imported or inherited by the node's JSON config file. -* **Copy required files to node**: All the files needed for puppet to run are rsync'ed to each node. This includes the entire leap_platform directory, as well as the node's hiera file and other files needed by puppet to set up the node (keys, binary files, etc). -* **Puppet is run**: Once the node is ready, leap connects to the node via ssh and runs `puppet apply`. Puppet is applied locally on the node, without a daemon or puppetmaster. - -You can run `leap -v2 deploy` to see exactly what commands are being executed. - -This mode of operation is fundamentally different from how puppet is normally used: - -* There is no puppetmaster that all the servers take orders from, and there is no puppetd running in the background. -* Servers cannot dynamically query the puppetmaster for information about the other servers. -* There is a static representation for the state of every server that can be committed to git. - -There are advantages and disadvantages to the model that LEAP uses. We have found it very useful for our goal of having a common LEAP platform that many different providers can all use while still allowing providers to configure their unique infrastructure. - -We also find it very beneficial to be able to track the state of your infrastructure in git. - -Traditional system configuration automation systems, like [Puppet](https://puppetlabs.com/puppet/puppet-open-source/) or [Chef](http://www.opscode.com/chef/), deploy changes to servers using a pull method. Each server pulls a manifest from a central master server and uses this to alter the state of the server. - -Instead, the `leap` tool uses a masterless push method: The sysadmin runs `leap deploy` from the provider instance directory on their desktop machine to push the changes out to every server (or a subset of servers). LEAP still uses Puppet, but there is no central master server that each node must pull from. - -One other significant difference between LEAP and typical system automation is how interactions among servers are handled. Rather than store a central database of information about each server that can be queried when a recipe is applied, the `leap` command compiles static representation of all the information a particular server will need in order to apply the recipes. In compiling this static representation, `leap` can use arbitrary programming logic to query and manipulate information about other servers. - -These two approaches, masterless push and pre-compiled static configuration, allow the sysadmin to manage a set of LEAP servers using traditional software development techniques of branching and merging, to more easily create local testing environments using virtual servers, and to deploy without the added complexity and failure potential of a master server. diff --git a/doc/guide/keys-and-certificates.md b/doc/guide/keys-and-certificates.md deleted file mode 100644 index a6862a6a..00000000 --- a/doc/guide/keys-and-certificates.md +++ /dev/null @@ -1,272 +0,0 @@ -@title = "Keys and Certificates" -@summary = "Working with SSH keys, secrets, and X.509 certificates." - -Working with SSH -================================ - -Whenever the `leap` command needs to push changes to a node or gather information from a node, it tunnels this command over SSH.

Since local nodes only exist for a short time on your computer and can't be reached from the internet, this is not a problem. - -Specifically, for local nodes: - -1. `known_hosts` is never updated with local node keys, since the SSH public key of a local node is different for each user. -2. `leap` entirely skips the checking of host keys when connecting with a local node. -3. `leap` adds the public Vagrant SSH key to the list of SSH keys for a user. The public Vagrant SSH key is a shared and insecure key that has root access to most Vagrant virtual machines. - -To upgrade a SSH host key -------------------------------- - -Most servers will have more than one SSH host key. Sometimes, the server will have a better SSH host key than the one you have on file. In order to upgrade to the better SSH host key, simply re-run the init command: - - workstation$ leap node init NODE_NAME - -This will prompt you if you want to upgrade the SSH host key, but only if `leap` thinks that an upgrade is advisable. - -When SSH host key changes -------------------------------- - -If the host key for a node has changed, you will get an error "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED". - -To fix this, you need to remove the file `files/nodes/stompy/stompy_ssh.pub` and run `leap node init stompy`, where the node's name is 'stompy'. **Only do this if you are ABSOLUTELY CERTAIN that the node's SSH host key has changed**. - -Changing the SSH port --------------------------------- - -Suppose you have a node `blinky` that has SSH listening on port 22 and you want to make it port 2200. - -First, modify the configuration for `blinky` to specify the variable `ssh.port` as 2200. Usually, this is done in `common.json` or in a tag file. - -For example, you could put this in `tags/production.json`: - - { - "ssh": { - "port": 2200 - } - } - -Run `leap compile` and open `hiera/blinky.yaml` to confirm that `ssh.port` is set to 2200. The port number must be specified as a number, not a string (no quotes). - -Then, you need to deploy this change so that SSH will bind to 2200. You cannot simply run `leap deploy blinky` because this command will default to using the variable `ssh.port` which is now `2200` but SSH on the node is still bound to 22. - -So, you manually override the port in the deploy command, using the old port: - - leap deploy --port 22 blinky - -Afterwards, SSH on `blinky` should be listening on port 2200 and you can just run `leap deploy blinky` from then on. - -Sysadmins with multiple SSH keys ------------------------------------ - -The command `leap add-user --self` allows only one SSH key.

To see what values are used for your provider, run `leap inspect provider.json`. - -NOTE: A certificate `bit_size` greater than 2048 will probably not be recognized by most commercial CAs. - -Certificate Authorities ------------------------------------------ - -There are three x.509 certificate authorities (CA) associated with your provider: - -1. **Commercial CA:** It is strongly recommended that you purchase a commercial cert for your primary domain. The goal of platform is to not depend on the commercial CA system, but it does increase security and usability if you purchase a certificate. The cert for the commercial CA must live at `files/cert/commercial_ca.crt`. -2. **Server CA:** This is a self-signed CA responsible for signing all the **server** certificates. The private key lives at `files/ca/ca.key` and the public cert lives at `files/ca/ca.crt`. The key is very sensitive information and must be kept private. The public cert is distributed publicly. -3. **Client CA:** This is a self-signed CA responsible for signing all the **client** certificates. The private key lives at `files/ca/client_ca.key` and the public cert lives at `files/ca/client_ca.crt`. Neither file is distribute publicly. It is not a big deal if the private key for the client CA is compromised, you can just generate a new one and re-deploy. - -To generate both the Server CA and the Client CA, run the command: - - leap cert ca - -Server certificates ------------------------------------ - -Most every server in your service provider will have a x.509 certificate, generated by the `leap` command using the Server CA. Whenever you modify any settings of a node that might affect it's certificate (like changing the IP address, hostname, or settings in provider.json), you can magically regenerate all the certs that need to be regenerated with this command: - - leap cert update - -Run `leap help cert update` for notes on usage options. - -Because the server certificates are generated locally on your personal machine, the private key for the Server CA need never be put on any server. It is up to you to keep this file secure. - -Client certificates --------------------------------- - -Every leap client gets its own time-limited client certificate. This cert is use to connect to the OpenVPN gateway (and probably other things in the future). It is generated on the fly by the webapp using the Client CA. - -To make this work, the private key of the Client CA is made available to the webapp. This might seem bad, but compromise of the Client CA simply allows the attacker to use the OpenVPN gateways without paying. In the future, we plan to add a command to automatically regenerate the Client CA periodically. - -There are two types of client certificates: limited and unlimited. A client using a limited cert will have its bandwidth limited to the rate specified by `provider.service.bandwidth_limit` (in Bytes per second). An unlimited cert is given to the user if they authenticate and the user's service level matches one configured in `provider.service.levels` without bandwidth limits. Otherwise, the user is given a limited client cert. - -Commercial certificates ------------------------------------ - -We strongly recommend that you use a commercial signed server certificate for your primary domain (in other words, a certificate with a common name matching whatever you have configured for `provider.domain`). This provides several benefits: - -1. When users visit your website, they don't get a scary notice that something is wrong. -2. When a user runs the LEAP client, selecting your service provider will not cause a warning message. -3. When other providers first discover your provider, they are more likely to trust your provider key if it is fetched over a commercially verified link. - -The LEAP platform is designed so that it assumes you are using a commercial cert for the primary domain of your provider, but all other servers are assumed to use non-commercial certs signed by the Server CA you create. - -To generate a CSR, run: - - leap cert csr - -This command will generate the CSR and private key matching `provider.domain` (you can change the domain with `--domain=DOMAIN` switch). It also generates a server certificate signed with the Server CA. You should delete this certificate and replace it with a real one once it is created by your commercial CA. - -The related commercial cert files are: - - files/ - cert/ - domain.org.crt # Server certificate for domain.org, obtained by commercial CA. - domain.org.csr # Certificate signing request - domain.org.key # Private key for you certificate - commercial_ca.crt # The CA cert obtained from the commercial CA. - -The private key file is extremely sensitive and care should be taken with its provenance. - -If your commercial CA has a chained CA cert, you should be OK if you just put the **last** cert in the chain into the `commercial_ca.crt` file. This only works if the other CAs in the chain have certs in the debian package `ca-certificates`, which is the case for almost all CAs. - -If you want to add additional fields to the CSR, like country, city, or locality, you can configure these values in provider.json like so: - - "ca": { - "server_certificates": { - "country": "US", - "state": "Washington", - "locality": "Seattle" - } - } - -If they are not present, the CSR will be created without them. - -Examine Certs ------------------ - -To see details about the keys and certs you can use `leap inspect` like so: - - $ leap inspect files/ca/ca.crt - - -Let's Encrypt certificate -========================= - -LEAP plans to integrate [Let's Encrypt](https://letsencrypt.org/) support, so it will be even easier to receive X.509 certificates that are accepted by all browsers. -Until we achieve this, here's a guide how to do this manually. - -Install the official acme client --------------------------------- - -Log in to your webapp node - - server$ git clone https://github.com/letsencrypt/letsencrypt - server$ cd letsencrypt - server$ ./letsencrypt-auto --help - -Fetch cert ----------- - -Stop apache so the letsencrypt client can bind to port 80: - - server$ systemctl stop apache2 - -Fetch the certs - - server$ ./letsencrypt-auto certonly --standalone --email admin@$(hostname -d) -d $(hostname -d) -d api.$(hostname -d) -d $(hostname -f) -d nicknym.$(hostname -d) - -This will put the certs and keys into `/etc/letsencrypt/live/DOMAIN/`. - -Now, go to your workstation's provider configuration directory and copy the newly created files from the server to your local config.

This location information is used for two things: - -* Determine which nodes can, or must, communicate with one another via a local network. The way some virtualization environments work, like OpenStack, requires that nodes communicate via the local network if they are on the same network. -* Allows the client to prefer connections to nodes that are closer in physical proximity to the user. This is particularly important for OpenVPN nodes. - -The location stanza in a node's config file looks like this: - - { - "location": { - "id": "ankara", - "name": "Ankara", - "country_code": "TR", - "timezone": "+2", - "hemisphere": "N" - } - } - -The fields: - -* `id`: An internal handle to use for this location. If two nodes have match `location.id`, then they are treated as being on a local network with one another. This value defaults to downcase and underscore of `location.name`. -* `name`: Can be anything, might be displayed to the user in the client if they choose to manually select a gateway. -* `country_code`: The [ISO 3166-1](https://en.wikipedia.org/wiki/ISO_3166-1) two letter country code. -* `timezone`: The timezone expressed as an offset from UTC (in standard time, not daylight savings). You can look up the timezone using this [handy map](http://www.timeanddate.com/time/map/). -* `hemisphere`: This should be "S" for all servers in South America, Africa, or Australia. Otherwise, this should be "N". - -These location options are very imprecise, but good enough for most usage. The client often does not know its own location precisely either. Instead, the client makes an educated guess at location based on the OS's timezone and locale. - -If you have multiple nodes in a single location, it is best to use a tag for the location. For example: - -`tags/ankara.json`: - - { - "location": { - "name": "Ankara", - "country_code": "TR", - "timezone": "+2", - "hemisphere": "N" - } - } - -`nodes/vpngateway.json`: - - { - "services": "openvpn", - "tags": ["production", "ankara"], - "ip_address": "1.1.1.1", - "openvpn": { - "gateway_address": "1.1.1.2" - } - } - -Unless you are using OpenStack or AWS, setting `location` for nodes is not required. It is, however, highly recommended. - -Disabling Nodes -===================================== - -There are two ways to temporarily disable a node: - -**Option 1: disabled environment** - -You can assign an environment to the node that marks it as disabled. Then, if you use environment pinning, the node will be ignored when you deploy. For example: - - { - "environment": "disabled" - } - -Then use `leap env pin ENV` to pin the environment to something other than 'disabled'. This only works if all the other nodes are also assigned to some environment. - -**Option 2: enabled == false** - -If a node has a property `enabled` set to false, then the `leap` command will skip over the node and pretend that it does not exist. For example: - - { - "ip_address": "1.1.1.1", - "services": ["openvpn"], - "enabled": false - } - -**Options 3: no-deploy** - -If the file `/etc/leap/no-deploy` exists on a node, then when you run the commmand `leap deploy` it will halt and prevent a deploy from going through (if the node was going to be included in the deploy). diff --git a/doc/guide/provider-configuration.md b/doc/guide/provider-configuration.md deleted file mode 100644 index 08cfd1dd..00000000 --- a/doc/guide/provider-configuration.md +++ /dev/null @@ -1,79 +0,0 @@ -@title = "Provider Configuration" -@summary = "Explore how to configure your provider." - -Required provider configuration --------------------------------------- - -There are a few required settings in `provider.json`.
