Example repository for a upstream/downstream setup. This is upstream.
If you want to try this setup, fork both this and the downstream repository and modify the following vars in travis.yml:
DOWNSTREAM_REPO:{user}/{repo}point to your downstream forksecure: [... gibberish ...]These need to be replaced by secret tokens for GitHub and Travis.
You can either go the road of registering this as your own application and authorizing this using GitHubs automated OAUTH token generation, or we simply create a restricted personal token.
For my usecase the laster was enough, so thats why I document this here.
Got to your personal token settings and create a new token with scope repo:status.
This will allow this script to change the build status of all repositories you have push access to.
Copy this token and save locally. DON'T PUT THIS TOKEN UNENCRYPTED INTO YOUR TRAVIS CONFIG
Now install the travis cli and encrypt your token. This will look something like this:
travis login
travis encrypt -r ${UPSTREAM_REPO} GITHUB_TOKEN=${YOUR_TOKEN}
Where ${UPSTREAM_REPO} for me would be TheMarex/example-travis-upstream.
Copy the result in the .travis.yml.
We also need a token for travis. We already installed the cli, so this will be simple:
travis login
travis token # copy this
travis encrypt -r ${UPSTREAM_REPO} TRAVIS_TOKEN=${TRAVIS_TOKEN}
Put the result again in your .travis.yml.
