[Enhancement]: Some ideas for testcontainers-go

[mmorel-35]

Proposal

There are several ideas I can see concerning testcontainers-go, some concerning modulegen, some concerning the CI/CD.

Modulegen

• extract mkdocs example.md file generation in /internal/mkdocs modulegen: generate md file inside internal/mkdocs #1543
• extract Makefile file generation in /internal/make modulegen: create internal/make #1537
• extract example.go and example_test.go file generation in /internal/module modulegen: create internal/module and internal/modfile #1539
• extract go.mod file generation in /internal/module and replace html/template with golang.org/x/mod/modfile to directly read from main go.mod modulegen: create internal/module and internal/modfile #1539
• Replace templates functions with Example attributes
• use github.com/spf13/cobra to handle the commands modulegen: use cobra instead of native golang flag #1550

CI/CD

• Provide code coverage to sonarcloud (starting with main module) chore(ci): enable code coverage on Sonarcloud #1518
• Generate sonar-project.properties per module/example ?
• Change dependabot updates schedule interval to "weekly" to address updates more frequently so it doesn't become an epic task every month ?
• Move Image of the example/module to a Dockerfile to be able to receive updates from dependabot ?
• trigger a go mod tidy on every module depending on the main one when it is modified

I'm much more focused on modulegen for the moment

Change dependabot updates schedule interval to "weekly" to address updates more frequently so it doesn't become an epic task every month ?

We already had that schedule, and there were lots of updates, exhausting the free tier of our GH actions workers across the entire testcontainers organisation.

I guess that at that time there was no groups for the updates. Would it helps smooth the process?
Another option would be to replace dependabot with renovate.

Move Image of the example/module to a Dockerfile to be able to receive updates from dependabot ?

Regarding this, I'd say no, as we want to keep modules stable, at least until we have a real support matrix (which we do not have). Also moving to a Dockerfile-based module will force users to build the image again and again.

Just in case, I'm exploring updatecli for certain updates

@mmorel-35 I have a working branch creating cmd/devtools as the primary way to run several things:

• the module generator
• the release shell script, migrated to Go
• the Go bump shell script
• checking that there are no containers running shell script
• other administrative tasks that could come?

Would you like to take a look and review it if possible? I appreciate your valuable feedback about this kind of tasks

Hi @mdelapenya ,
Of course, please provide a PR or the branch I can review
