GitOps is nice and all, but how to implement GitOps may not be so easy. In this article we’ll see an example implementation using GitLabCI and AWS. We’ll talk a lot about GitOps, GitLabCI and AWS. If you haven’t already heard about GitOps, here are some nice articles from Weaveworks and GitLab. Minimal example Let’s…
We’ll use a minimalist method to deploy a static website using a custom domain name with AWS S3, Route 53 and CloudFormation. Our stack will contain: An S3 bucket holding our website content with a public access policy The bucket will act as storage for our website data (HTML, CSS, etc.), we’ll just need to…
When building Docker images with GitlabCI, a very common issue is setting-up efficient Docker caching strategy for image build. That’s when hell starts and your CI jobs gets either longer, complex or both. Introduction We’ll talk a lot about Docker and Gitlab CI If you are not familiar with GitlabCI Runner, I advise you to…
