Travis CI - Using repository environment variables in .travis.yml

Question

I'm looking to declare environment variables in my Travis CI repository settings and use them in my .travis.yml file to deploy an application and post a build notification in Slack.

I've set environment variables in my Travis CI repository settings like so:

My .travis.yml file appears as the following:

language: node_js node_js:   - '0.12' cache:   directories:     - node_modules deploy:   edge: true   provider: cloudfoundry   api: $CF_API   username: $CF_USERNAME   password: $CF_PASSWORD   organization: $CF_ORGANIZATION   space: $CF_SPACE notifications:   slack: $NOTIFICATIONS_SLACK 

When I add the values into the .travis.yml file as they are, everything works as planned.

However, when I try to refer to the environment variables set in the repository, I receive no Slack notification on a build status, and the deployment fails.

Am I following this process correctly or is there something I'm overseeing?

Answer 1

I think it is probably too early in Travis CI's sequence for your environment variables to be read.

What I would suggest is to rather encrypt them using the travis command-line tool.

E.g.

$ travis encrypt Reading from stdin, press Ctrl+D when done username Please add the following to your .travis.yml file:  secure: "TD955qR6qvpVIz3fLkGeeUhV76deeVRaLVYjW9YjV6Ob7wd+vPtACZ..."  Pro Tip: You can add it automatically by running with --add. 

Then I would copy/paste the secure: "TD955qR6qvpVIz3fLkGeeUhV76d..." result at the appropriate place in your .travis.yml file:

language: node_js node_js:   - '0.12' cache:   directories:     - node_modules deploy:   edge: true   provider: cloudfoundry   api:     secure: "bHU4+ZDFeZcHpuE/WRpgMBcxr8l..."   username:     secure: "TD955qR6qvpVIz3fLkGeeUhV76d..." 

You can have more details about how to encrypt sensitive data on Travis CI here.

Hope this helps.
