Development is super fast these days, there are many tools and integrations to make it more comfortable. One of the version control systems is Git, next to well-known SVN and CVS. Git got really pushed by GitHub and most recently GitLab which provide entire collaboration suites. Nowadays you not only commit code revisions/diffs, you can also test and deployment changes immediately to see whether your code is good on defined platforms or breaks. Issue and project management is put on top and makes it very easy to collaborate.
Continuous integration (CI) allows for deeper code quality too. Add code coverage reports, unit test results, end2end tests and actually build distribution packages with tests on many platforms included. In addition to CI, continuous deployment (CD) adds the icing on the cake. Once CI tests and package builds are fine, add a new build job to your pipeline for automated deployments. This could for example push updated RPM packages for your repository and immediately install the bugfix release in production on all your client hosts with Puppet or Ansible.
You can do all of this with the ease of GitHub or your own hosted GitLab instance (try it out in NWS right now!). Don’t forget about the basics for development and devops workflows:
- Untracked files, staging area, … what’s within the .git directory?
- What is a „good commit„?
- I want to create patch for an open source project – what’s a „pull request„?
- Workflow with branches?
- A developer asked me to „rebase your branch against master“ and „squash the commits“ … what’s that?
Our Git training sessions have been renewed into a two day hands-on session on Git and GitLab. Many of us are using Git on a daily basis at NETWAYS, in addition to GitLab. Knowledge which we share and improve upon. The training starts with the Git basics, diving into good commits, branching, remote repositories and even more. Day 1 also provides your own NWS hosted GitLab instance.
Starting with day 2, you’ll learn about development workflows with branches and real-life use cases. Continuing with CI/CD and generating your own Job pipeline, and exploring GitLab even further. We’ll also discuss integrations into modern development tools (Visual Studio, JetBrains, etc.) and have time to share experiences from daily work. I’ve been working with Git since the beginning of Icinga more than nine years ago.
We have open-sourced our GitLab training material. We truly believe in Open Source and want make it easier for development and contributions on your favourite OSS project, like Icinga.
You are welcome to use our training material for your own studies, especially if you are an open source developer who’s been learning to use Git, GitLab and GitHub. For offline convenience, the handouts, exercises and solutions are provided as PDF too.
Many of the mentioned practical examples and experiences are only available in our two day training sessions at NETWAYS so please consider getting a ticket. There’s also time for your own experience and ideas – the previous training sessions have shown that you can always learn something new about Git. You can see that in the Git repository and the newer Git commits, where this feedback was added to the training material ❤️
See you soon at the famous NETWAYS Kesselhaus for a deep-dive into Git and GitLab!
