Extending build containers: Generic caching
Declaring your build environment by using Dockerfiles and creating separate containers for each and every build is good practice. But starting in a fresh environment each time prevents various caching mechanisms from having any effect. The result is an increase in build time as well as network traffic, where especially the latter can cause some bottlenecking to occur. This affects mainly git repositories, build tools like Maven and npm, but also Docker builds itself. The git repository has to be cloned from scratch. Dependencies for Maven and npm have to be fetched from their official repositories on every build, even if the majority did not change. In case of Docker builds, at least the base image must be pulled. The Docker build cache is also empty. …

Remote debugging containerized Jenkins builds: debugShell()
Providing build environments by employing some kind of container technology is quite common nowadays. When looking at Docker as an example, it offers various benefits: Declaring the environment in a textual way by using a Dockerfile , you can combine it with a versioning tool like git and track every change. Each build is running inside its own fresh container and is therefore isolated and also reproducible. If you choose to use a clustering solution like Docker Swarm or Kubernetes, you’re also able to dynamically scale available build power at run time. …
