The Docker images we provide for both Icinga 2 and Icinga Web 2 already contain quite a number of modules. For example, the Icinga Web 2 image contains all the Web modules developed by us.

Flux is a CNCF based open source stack of tools. Flux focuses on making it possible to keep Kubernetes clusters and cloud-native applications in sync with external resources and definitions hosted in environments such as GitHub. Implementing tools like FluxCD should enable you to achieve results such as: The results above can bring obvious benefits, and many teams are adopting FluxCD as their tool of choice for GitOps.

Bitbucket Pipelines provides a Docker caching feature that can help improve build times. However, the limitation is that only compressed caches under 1GB are saved and can be used. In this blog, we outline a process showing how you can use compressed caches that are larger than 1GB. With Docker versions >= 19.03, you can use the BuildKit feature.
