In one of the previous posts, I described the way I’m using GitLab to build and test images. Despite the fact that it’s pretty simple configuration and actual tests are run for less than a minute, complete pipeline takes around 20 minutes. Which seems very unreasonable. I spent some time digging out the problem and was able to reduce build time to around 3 minutes. Here are few things, that should be considered to optimize pipeline.
Using Kubernetes ScheduledJobs and DigitalOcean API to get free DynDNS analog.
DynDNS is annoying/expensive I’m using different DynDNS services at home for the last few years. It’s easy to use, comes preinstalled on most of the routers. The only annoyance is the need to confirm each of your hosts every 30 days And it’s fine because you do not pay anything. Recently, I wanted to attach proper domain to my home server to be able to access my Kubernetes from the outside.
In my previous posts I described how to deploy GitLab to Kubernetes and configure GitLab-CI to build and test docker containers. In this one, I’m going to write about continues deployments. I assume that you already have Kubernetes cluster and application running, and you have some manual way of deploying your application to it. So I will not touch the basics of writing Kubernetes manifests. But I will briefly describe my own scripts and show how I configured GitLab-CI to automate deployment.
How to configure GitLab CI to build,test and release python containers with javascript and webpack.
In the previous post I described how to run own GitLab server with CI runner. In this one, I’m going to walk through my experience of configuring GitLab-CI for one of my projects. I faced few problems during this process, which I will highlight in this post. Some words about the project: Python/Flask backend with PostgreSQL as a database, with the bunch of unittests. React/Reflux in frontend with Webpack for bundling.
How to easily deploy GitLab with GitLab CI to Kubernetes cluster
I spent some time recently researching how to build CI/CD pipeline to automate testing and deploying. Since I’m developing everything in containers and use Kubernetes to manage it GitLab with its CI runners and recent integrations with k8s seemed like a good option. In this post, I will describe the steps needed to get GitLab with GitLab Runner, up and running on top of Kubernetes. All manifests used in this post could be found here
