Travis CI

Travis CI is a completely free CI/CD option available with excellent integration to Github.

Configuration

Travis CI is configured with a .travis.yml file in a repository root. The .travis.yml defines the CI test suite that will be run by Travis.

Enabling build notifications to Slack

Travis document

Travis appears to use encryption keypairs on a per repository basis. This means that each repo's .travis.yml file needs an encrypted value generating.

Example command (from within git repo):

travis encrypt "jh-homelab:$SLACK_TOKEN" --add notifications.slack
