All right. Let's move on to example two. So in example two, we're basically going to make some small edits. Let's get back to the GitHub desktop. We'll start a new branch. We'll base that branch off the example that we worked on. This time we'll call this one module two, example two, and create this branch. So all of our changes from the previous branch example one branch are still there. We can build on this change that we made to talk about the after success phase. So the after success phase we can start by just typing after underscore success. What happens here is that, if you have a script that you want to run, only if we happen to have a successful build or a successful test, then this is a good way to execute that. Sometimes this is useful for doing publishing events like, maybe we want to tag in this case our docker image so that we might use it later on for a deployment. So, in this phase, let's just add a single-step to the after success phase. That says, "I'm going to docker tag" which labels the existing image called probot-hello. We're going to use the tag probot-hello, which is a general tag that we created for our build. We're going to give this tag a specific identifier that is controlled by the git commit that we are currently building. So we'll use a command called git rev dash parse space head. What that does is it expands into a show along a string of characters, which can then basically be used to uniquely identify the image that we're building for this particular build. So let me save the changes. We'll be back to the GitHub desktop. We will commit these changes, so we're testing the after success. Choose the commit button and publish those changes. Now let's go back to Travis. Let's see what that what happens with that particular build. So if we go back to the requests, let's see our example two looks like it's testing the after success. Let' syntactically correct. We can choose the branches and see module two example two branches now building. We can look at the view config and just confirm that, we're actually going to execute an after success and then watch the job log. So I'm going to pause the video at this point and let this finish to completion and then we can go look at the log file after the build completes. Okay. This build is now complete. Let's go look at what happened in the build. Sure enough, our test case is passed again and so did the run-length command. Now we have this additional after success phase that executed that created a new label for that particular branch. So we can see that in the after success face there.
