Paul Gschwendtner 13b96ac91d ci: run saucelabs unit tests as cronjob (#28787)
We no longer want to run Saucelabs for every PR/commit because
Saucelabs has been very flaky recently and it blocks most of the
PRs with a flaky failing state that we cannot fix most of the time due
to upstream Saucelabs failures/incidents. Since real browsers tests
rarely catch browser-specific failures (same as in Material), we should
only run Saucelabs in a cronjob on the upstream branches. This still
ensures/guarantees our browser compatibility, but makes our CI
more stable and the PR workflow more productive.

Encryption

Based on https://github.com/circleci/encrypted-files

In the CircleCI web UI, we have a secret variable called KEY https://circleci.com/gh/angular/angular/edit#env-vars which is only exposed to non-fork builds (see "Pass secrets to builds from forked pull requests" under https://circleci.com/gh/angular/angular/edit#advanced-settings)

We use this as a symmetric AES encryption key to encrypt tokens like a GitHub token that enables publishing snapshots.

To create the github_token file, we take this approach:

  • Find the angular-builds:token in http://valentine
  • Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime: docker run --rm -it circleci/node:10.12
  • echo "https://[token]:@github.com" > credentials
  • openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
  • If needed, base64-encode the result so you can copy-paste it out of docker: base64 github_token
