Overview

Deploy your app

There is a folder rel which is the output of the mix phx.gen.releae command. To know more about phoenix releases see (opens in a new tab).

The release written above is used to create the docker image of our app. In order to do so run:

docker build -t your/tag --build-arg MIX_ENV=yourenv .

Once the docker image has been built you need these variables to make it work:

  • DB_NAME
  • DB_HOSTNAME
  • DB_USER
  • DB_PASSWORD
  • RELEASE_NAME
  • SECRET_KEY_BASE run mix phx.gen.secret
  • SECRET_KEY_AUTH runmix guardian.gen.secret
  • HEADLESS_SERVICE_NAME

The docker image created is meant to be used in a kubernetes environment. If you want use it somewhere else please edit the runtime.exs file accordingly. Look for the libcluster topologies and set the right strategy. Remember to edit also the env.sh.eex file which export RELEASE_NODE=<%= @app_name %>@${POD_IP}, where POD_IP is inherited from the k8s pod.
