Trigger a Deployments from the Command Line

Now, we can use git to tag a commit and trigger the build.

$ git tag -a v1.0.1 -m "my version 1.0.1"
$ git push google v1.0.1

Back in the Cloud Console, we should see our image being built. After the image is in GCR, our build should kick off in Spinnaker. This may take a few minutes.

Rolling Back a Deployment from the Command Line

Use git to go back a commit, then push the image and bump the tag. I workshop have user make two commits (the 2nd of which is bad). When the user pushes them, have them follow this process.

# Change code
$ git add <change>
$ git commit -m "Working code fix."

# Change code
$ git add <change>
$ git commit -m "Broken code fix."

$ git push google master

$ git tag -a v3.0.0 -m "my version 3.0.0"
$ git push google v3.0.0

Roll back change

$ git <rollback one commit>
$ git commit -m "Rolled back buggy code."
$ git push google master
$ git tag -a v4.0.0 -m "my version 4.0.0"
$ git push google v4.0.0

Trigger a Builds and Rolling Back changes from the UI

You can also use the UI if you need an escape hatch.
