TrabianBot

TrabianBot does the dirty work.

Deployment

Deployment is handled via edeliver using distillery to create the releases.

Build a release

To create a release, start the docker environment using docker-compose up from the root directory. This will create a build container and a staging container running ssh daemons.

Configure SSH for build and staging containers

edeliver requires key-based authentication into the servers, including build and staging. The containers in this repo use an included ssh key, which is fine in this case because these environments aren't used outside of the build/staging process. However, edeliver doesn't currently support a custom ssh key location, so add the following to ~/.ssh/config:

Host build.trabianbot
  HostName localhost
  User root
  IdentityFile [repo path]/containers/build/ssh_key
  Port 11022

Host staging.trabianbot
  HostName localhost
  User staging
  IdentityFile [repo path]/containers/staging/ssh_key
  Port 11023

Create release

To create an initial (non-upgrade) release, run:

mix edeliver build release

Deploy to staging

To deploy to staging, run:

mix edeliver start

And verify using:

mix edeliver ping

If there are any issues with startup, log in to the staging server and check /web/trabian_bot/log/erlang.log.1. The binary at /web/trabian_bot/bin/trabian_bot can be used to run individual distillery commands, particularly when debugging. See https://hexdocs.pm/distillery/getting-started.html for more information.

For example, /web/trabian_bot/bin/trabian_bot remote_console will start an iex session attached to the running application.

Deploy to production

mix edeliver deploy release to production
mix edeliver start production
mix edeliver ping production
