Brad Warren 4e9d3afcc4 Docker build improvements (#8218) ... Fixes https://github.com/certbot/certbot/issues/8208. Fixes https://github.com/certbot/certbot/issues/8198. In addition to those two linked issues, this PR: * Splits both the build and deploy steps based on architecture for performance. The Docker builds should no longer be the bottleneck in any stage of the pipeline. * Skips building Docker images for ARM on `test-` branches like [we do for snaps](e8a232297d/.azure-pipelines/templates/jobs/packaging-jobs.yml (L67-L71)). I initially didn't want to do this, but the ARM builds take ~18 minutes which is significantly longer than any other job currently running on our `test-` branches. You can see tests running on my fork at: * [Release pipeline](https://dev.azure.com/bmw0523/bmw/_build/results?buildId=387&view=results) * [Test pipeline](https://dev.azure.com/bmw0523/bmw/_build/results?buildId=388&view=results) * [Nightly pipeline](https://dev.azure.com/bmw0523/bmw/_build/results?buildId=390&view=results) * update script intro * update readme * ParseRequestedArch * build all arch in Azure * Build docker images during testing/packaging. * require global variable? * Error if TAG_BASE is empty. * prepare build job * change variable syntax * Update deploy stage. * remove old dockerTag param * add displayName * fix docker images command * split docker_build by arch * Allow deploying a subset of architectures. * deploy in parallel * Skip ARM builds on test- branches. * fix spacing		2020-08-18 10:48:01 -07:00
