For example, you might have sets of nodes for ‘testing’, ‘staging’ and ‘production’.</p> + +<p>Typically, the nodes in one environment are totally isolated from the nodes in a different environment. Each environment will have its own separate database, for example.</p> + +<p>There are a few exceptions to this rule: backup nodes, for example, will by default attempt to back up data from all the environments (excluding local).</p> + +<h2><a name="assign-an-environment"></a>Assign an environment</h2> + +<p>To assign an environment to a node, you just set the <code>environment</code> node property. This is typically done with tags, although it is not necessary. For example:</p> + +<p><code>tags/production.json</code></p> + +<pre><code>{ + "environment": "production" +} +</code></pre> + +<p><code>nodes/mynode.json</code></p> + +<pre><code>{ + "tags": ["production"] +} +</code></pre> + +<p>There are several built-in tags that will apply a value for the environment:</p> + +<ul> +<li><code>production</code>: An environment for nodes that are in use by end users.</li> +<li><code>development</code>: An environment to be used for nodes that are being used for experiments or staging.</li> +<li><code>local</code>: This environment gets automatically applied to all nodes that run only on local VMs. Nodes with a <code>local</code> environment are treated special and excluded from certain calculations.</li> +</ul> + + +<p>You don’t need to use these and you can add your own.</p> + +<h2><a name="environment-commands"></a>Environment commands</h2> + +<ul> +<li><code>leap env</code> – List the available environments and disply which one is active.</li> +<li><code>leap env pin ENV</code> – Pin the current environment to ENV.</li> +<li><code>leap env unpin</code> – Remove the environment pin.</li> +</ul> + + +<p>The environment pin is only active for your local machine: it is not recorded in the provider directory and not shared with other users.</p> + +<h2><a name="environment-specific-json-files"></a>Environment specific JSON files</h2> + +<p>You can add JSON configuration files that are only applied when a specific environment is active. For example, if you create a file <code>provider.production.json</code>, these values will only get applied to the <code>provider.json</code> file for the <code>production</code> environment.</p> + +<p>This will also work for services and tags. For example:</p> + +<pre><code>provider.local.json +services/webapp.development.json +tags/seattle.production.json +</code></pre> + +<p>In this example, <code>local</code>, <code>development</code>, and <code>production</code> are the names of environments.</p> + +<h2><a name="bind-an-environment-to-a-platform-version"></a>Bind an environment to a Platform version</h2> + +<p>If you want to ensure that a particular environment is bound to a particular version of the LEAP Platform, you can add a <code>platform</code> section to the <code>provider.ENV.json</code> file (where ENV is the name of the environment in question).</p> + +<p>The available options are <code>platform.version</code>, <code>platform.branch</code>, or <code>platform.commit</code>. For example:</p> + +<pre><code>{ + "platform": { + "version": "1.6.1", + "branch": "develop", + "commit": "5df867fbd3a78ca4160eb54d708d55a7d047bdb2" + } +} +</code></pre> + +<p>You can use any combination of <code>version</code>, <code>branch</code>, and <code>commit</code> to specify the binding. The values for <code>branch</code> and <code>commit</code> only work if the <code>leap_platform</code> directory is a git repository.</p> + +<p>The value for <code>commit</code> is passed directly through to <code>git log</code> to query for a list of acceptable commits. See <a href="https://www.kernel.org/pub/software/scm/git/docs/gitrevisions.html#_specifying_ranges">man gitrevisions</a> to see how to specify ranges. For example:</p> + +<ul> +<li><code>HEAD^..HEAD</code> - current commit must be head of the branch.</li> +<li><code>3172444652af71bd771609d6b80258e70cc82ce9..HEAD</code> - current commit must be after 3172444652af71bd771609d6b80258e70cc82ce9.</li> +<li><code>refs/tags/0.6.0rc1..refs/tags/0.6.0rc2</code> - current commit must be after tag 0.6.0rc1 and before or including tag 0.6.0rc2.</li> +</ul> + + +</div> +</div> +</body> +</html> |
