I wanted to be able to test my build with and without the explicit caching. The upside of building Docker images on hosted agents I experienced both the highs and lows of moving to a hosted build platform recently. We hope to get back to fixing this before the end of the year, and will keep you posted here with any progress. That way those cached layers can be shared between different images.
After completing these steps, you can tag and push images as you normally would. That means, your Docker images will be frequently built and transferred. The Jenkins will spin up a container from this image and build artifacts inside the container.
This is usually your main application image. However, if you do let Docker use its cache, it is important to understand when it can, and cannot, find a matching image. Sharing the base image is still supported. Explanatory comments are included inline. A new instance will start with a Docker Engine ready to accept commands 4.
How to enable the npm cache in a Jenkins build slave that runs in docker? - Notice I've also tagged this stage using the :builder tag - I'll come back to this later when we put together the final script.
I have a repository that uses Docker Cloud infrastructure with cache enabled. If I add a build hook to a project, even a simple one:. Caching will no longer work on this project. Remove the hook, cache works, add the hook, cache breaks. This is a simplified example, but certain project require secrets stored and passed as build-args. Caching should be supported for these projects. When starting the builds we can see that the initial phase has somewhat different output. No build hook: Pulling cache layers for. docker build cache With build hook: Pulling cache layers for. Sending build context to Docker daemon 71.
