# Build new image

As an example we build a new version (2.2.0) of the leapcode/ruby image:

## Find latest version

I.e. look at the tags at https://hub.docker.com/r/leapcode/ruby/tags/ or query tags with:
 
    curl -s https://registry.hub.docker.com/v2/repositories/leapcode/jessie/tags/ |jq '."results"[]["name"]'

## Build new version

    VERSION='2.2.0'
    IMAGE='ruby'
    cd $IMAGE
    docker build --no-cache -t leapcode/${IMAGE}:${VERSION} .

## Push images

    docker logout
    docker login -u leapcode
    docker push leapcode/${IMAGE}:${VERSION}
    docker tag  leapcode/${IMAGE}:${VERSION} leapcode/${IMAGE}:latest
    docker push leapcode/${IMAGE}:latest
