A release process must be able to prove which build is running in production and to put the same build back if a problem appears. Which arrangement of the pipeline fits?

選択肢

1. Build from the source at each deployment and keep a copy of the archive on the machine that ran the build, so the archive can be found on that machine.
2. Publish every build to a repository under its own version and deploy from that repository, so the version that runs can be named and put back at any time.
3. Publish every build to a repository under the same version and deploy from that repository, so the newest build is the one that the pipeline finds.
4. Build from the source at each deployment and deploy from the working copy, so the state of the source decides what runs in each of the environments.
