The DevOps Toolkit: Working with Jenkins X

Exploring Quickstart Project Files

Explore the various project files generated by Jenkins X when creating quickstart projects. Understand the role of key files like Makefile, Dockerfile, Skaffold configuration, Helm charts for Kubernetes deployment, and the pipeline definition file jenkins-x.yml. Learn how Jenkins X integrates with GitHub to automate your CI/CD pipeline triggers.

We'll cover the following...

Exploring the Github repository

Let’s see what Jenkins X created and pushed to GitHub.

⚠️ Please replace [...] with your GitHub username before executing the commands that follow.

Shell
GH_USER=[...]
open "https://github.com/$GH_USER/jx-go"

We can see that Jenkins X created quite a few files.

Exploring the local project repository

The repository was also created locally, so let’s take a closer look at the generated files.

Shell
cd jx-go
ls -1

The output is as follows:

C++
Dockerfile
Makefile
OWNERS
OWNERS_ALIASES
README.md
charts
curlloop.sh
jenkins-x.yml
main.go
skaffold.yaml
watch.sh

The Makefile

Let’s go through each of those files and directories and explore what we got. The first in line is Makefile.

Shell
cat Makefile

I won’t go into much detail about the Makefile since it is made specifically for Go applications, and that might not be your favorite language. Not all quickstart packs use Makefile. Instead, each tends to leverage methods appropriate ...
