Docker / httpd: Configuration Error: No MPM Download

Question

I have a docker container based on the official httpd image. Out of nowhere (after a new build), it started crashing with an error:

AH00534: httpd: Configuration error: No MPM loaded.

Nothing more.

I am using the official httpd ( FROM httpd:2.4) image , and so far everything has been working fine.
The error appeared only after deleting all the images in my system usingdocker system prune -af

Answer 1

(edit, thanks delboy1978uk ) This error can be avoided by applying a simple recommendation: attach the docker images to a specific version, not to latest.

After searching for commits of the official httpd image, I found a solution. (maybe this question / answer may help others)
