Description

This is a deployment of Dokku, a docker-powered PaaS that helps you build and manage the lifecycle of applications.

Configuration

In order to configure apps use the dokku_apps variable:

dokku_apps:
  - name: 'my-awesome-bot'
    repo: 'https://github.com/status-im/my-awesome-bot'
    env:
      APP_ID: 12345
      LOG_LEVEL: debug
      WEBHOOK_SECRET: 'my-github-webhook-secret'
      PRIVATE_KEY: 'my-secret-private-key'

Known Issues

Docker Container Renaming

Because we redirect logs to rsyslog and then to files in /var/log/docker as well as Logstash, and the way Docker handles container renaming, when Dokku renames containers their logs still flow to the randomly generated name, rather then the propper app name.

For this reason a hacky workaround has been added to the tasks/post_config.yml file which modifies Dokku script files.

Docker User Namespaces

Currently Dokku is unable to properly work with Docker user namespace settings.

For that reason we are using a hacky workaround in tasks/dockremap.yml which simply changes the user in Docker userns-remap setting to dokku rather than dockremap.

This allows us to use to the user namespaces without getting chmod errors on container start.
