George Kalpakas 07fa97c831 ci: remove unnecessary retry for docs examples tests (#39905)
In #32497, an option was introduced to retry failed docs examples tests
a second time. This was done to work around some then recently
introduced flakiness. After inspecting ~50 recent CI docs examples jobs,
all tests passed on the first try.

This commit gets rid of the retry attempt. This will avoid covering up
any new flakiness introduces in the future.

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 the internal pw database
  • 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
