Not Running on Windows: Suspected Bug in Dockerfile

[Chris-Maechler]

Somewhere after version 8.1.8 the zeebe container is constantly restarting because it cannot access files in /usr/local/zeebe/data/ (.topology.meta in 8.4.0). I'm using the .env and Dockerfile from this repository. All other containers like different databases, kibana, keycloak, my own images, etc. run completely fine.

According to the official Dockerfile documentation:

If any build steps change the data within the volume after it has been declared, those changes will be discarded.

So you would have to move VOLUME declarations down after you create the directories and after the COPY instructions.

I also read somewhere that VOLUME would create an empty directory if it doesn't exist yet. In this case mkdir would fail and because you chain with && the chown and chmod would be ignored.

Seems like removing older volumes, created by earlier images, solves these issues.

@Chris-Maechler Thanks for reporting this.
Could you please provide more info about the versions? (e.g. OS, Docker daemon and CLI versions) and how to reproduce the issue.

[Chris-Maechler]

Yes, dwknippers is right, deleting the volumes solved the problem.
