Previously, we needed to manually specify a ChromeDriver version to download on CI that would be compatible with the browser version provided by the docker image used to run the tests. This was kept in the `CI_CHROMEDRIVER_VERSION_ARG` environment variable. With recent commits, we use the browser provided by `puppeteer` and can determine the correct ChromeDriver version programmatically. Therefore, we no longer need the `CI_CHROMEDRIVER_VERSION_ARG` environment variable. NOTE: There is still one place (the `bazel-schematics` integration project) where a hard-coded ChromeDriver version is necessary. Since I am not sure what is the best way to refactor the tests to not rely on a hard-coded version, I left it as a TODO for a follow-up PR. PR Close #35381
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
