In #35049, integration and AIO tests were changed to use the browser provided by `puppeteer` in tests. This commit switches the docs examples tests to use the same setup. IMPLEMENTATION NOTE: The examples are used to create ZIP archives that docs users can download to experiment with. Since we want the downloaded projects to resemble an `@angular/cli` generated project, we do not want to affect the project's Protractor configuration in order to use `puppeteer`. To achieve this, a second Protractor configuration is created (which is ignored when creating the ZIP archives) that extends the original one and passes the approperiate arguments to use the browser provided by `puppeteer`. This new configuration (`protractor-puppeteer.conf.js`) is used when running the docs examples tests (on CI or locally during development). 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
