NO-ISSUE: Use image-builder and maven-m2-repo-via-http-image to build serverless-logic-web-tools-swf-dev-mode-image

[thiagoelg]

This PR refactors the build process of the serverless-logic-web-tools-swf-dev-mode-image package to use our image-builder and maven-m2-repo-via-http-image tools.

With this change, the local m2 repository is served via a Docker container inside the same Docker network as the builder container, making it possible to fetch all locally built dependencies to Maven during build/install.

The dev-mode image now runs in offline mode, as the m2-repo container is unavailable during runtime. Still, all dependencies should already be available inside the container's filesystem (in /home/kogito/.m2/repository).

The --ulimit nofile=5000:5000 flags from the Docker build command were removed as image-builder doesn't support passing flags to the Docker CLI for now. If the CI breaks, we can implement it.

@fantonangeli can you help validate that the image still works as expected?

[fantonangeli]

I still have to read all the code.
In OpenShift I get the error ImagePullBackOff
"Back-off pulling image "docker.io/apache/incubator-serverless-logic-web-tools-swf-dev-mode:main""

Are we supposed to wait the release to test this as it is under apache path?

@thiagoelg @tiagobento
The image works well for me locally but when I try it in OpenShift I get this error.
Did you manage to test it in OpenShift?

@fantonangeli can you provide the steps to reproduce this? I think I know how to fix it, but I need to test.

Updated the PR to include two changes:

• Used a mounted path (/tmp/app) to copy all executable and mutable files and run the app from there (check entrypoint.sh);
• Added the memory resource limit to 4096Mi. This allows the image to run on an OpenShift Developer Sandbox.

I tested it with a JSONGreet example, and it worked fine on the Dev UI, but the webapp that can be accessed via this "Dev Mode for Serverless Workflow" button crashed and never recovered (I'm not sure if this was happening before this change or if it's an out of memory thing).

@thiagoelg I'm sorry I still have this error, what am I missing?

@fantonangeli Your OCP cluster probably cached the previous version (to always pull the image, the Deployment needs to be configured with imagePullPolicy: Always)

I've published the same image under the latest tag now. Could you try that? Thanks!

[fantonangeli]

Tested and works well. Thanks @thiagoelg
