ERROR: Module xxx does not exist!

[oozman]

I'm getting a bunch of Module does not exist issue after doing:

docker-slim build thecodingmachine/php:7.3-v2-apache-node12

Running the slim container returns:

ERROR: Module actions does not exist!
ERROR: Module allowmethods does not exist!
ERROR: Module asis does not exist!
ERROR: Module auth_digest does not exist!
.
.
.
ERROR: Module substitute does not exist!
ERROR: Module suexec does not exist!
ERROR: Module unique_id does not exist!
ERROR: Module userdir does not exist!
ERROR: Module usertrack does not exist!
ERROR: Module vhost_alias does not exist!
ERROR: Module xml2enc does not exist!

Am I missing something?

Thanks

@OmarUsman It might be related to Apache... I'll need to double check. I assume this is the Docker image: https://github.com/thecodingmachine/docker-images-php/blob/v3/Dockerfile.apache.node12

It does look like you are running docker-slim against a base image and not an application image, so it's not surprising that something is missing. It is possible to use docker-slim with base images, but it requires extra work where you need to explicitly tell docker-slim the extra artifacts/modules/packages/files you'll need.

@kcq I went into this issue myself as well (using the master build)

essentially what I've seen is that some files in /var/www/modules are kept but they are zero sized.

the date says the DS was touching them.

the /etc/apache2/httpd.conf references the following line and its not commented out:

[kcq]

@pentium10 the bad magic number errors are ok... it's a side effect trying to detect which included files are also binary files

need to investigate the relocating errors

[kcq]

@pentium10 latest code in master might be able to address the errors you observed
