Hello @SamuelMarks,

If you want to build the Docker image locally (from the source), you first need to build the kroki-server.jar file.

Before running make buildDockerImages, you need to run make installLocalDependencies and make buildServer to compile and create a jar file from the Java sources.

You can take a look at the GitHub Action workflow to know which tasks you need to run:

https://github.com/yuzutech/kroki/blob/fdf28d344c727304883250356a03688573bca3ba/.github/workflows/main.yaml#L54-L65

So more than 25GB is required for the docker build -t yuzutech/kroki-bpmn . stage?

Kroki images are relatively small but Docker can consume a lot of space during build. I don’t have the exact number but it can grow quickly.

(I’m rerunning it after a docker system prune -a in case something built [wrong] last time was causing an issue)

Keep us updated 😉 If you have multiple partitions or file systems, make sure that you have free space on them too. On my system (Linux), Docker is using /var/lib/docker.
