Now It Is Your Turn

Creating a Jenkins job that upgrades the whole production environment

Before we upgrade the production environment, we'll create one more release of go-demo-5 so that we have something new to deploy.

We opened the branches screen of the go-demo-5 job.

Please click the play button from the right side of the master row and wait until the new build is finished.

Lo and behold! Our build failed! If you explore the job in detail, you will know why it's broken.

You'll see Did you forget to increment the Chart version? message.

Figure 8-3: go-demo-5 failed build

Our job does not allow us to push a commit to the master branch without bumping the version of the go-demo-5 chart. That way, we guarantee that every production-ready release is versioned correctly. Let's fix that.
