Use dotnet image for godot 4

[AdrasteonDev]

This pull request allows to use the .NET Docker image instead of the mono image for Godot 4 (the mono image is still used for Godot 3). It is related to #80 (it adds the possibility to use the dotnet command for Godot 4).

As long as there is currently no godot-ci image for Godot 4 on Docker Hub, it will not break existing CI pipelines for Godot 4.

I decided to use "dotnet/sdk:6.0-focal" because I could not install "python-openssl" with the "bullseye-slim" version (and because focal is also used in the dockerfile of the non-mono version of Godot).

I also added a few comments in the YAML files related to Godot 4, and I corrected a bug in mono.Dockerfile.

I made sample projects to be sure that the images are usable for CI:

• https://gitlab.com/Adrasteon/test-godot-ci-for-godot-3.5-mono
• https://gitlab.com/Adrasteon/test-godot-ci-for-godot-4-mono
• https://gitlab.com/Adrasteon/test-godot-ci-for-godot-4-without-mono

I verified that the Linux and Windows executables created by the CI pipelines of these projects run correctly.

Let me know if you have any comments or suggestions about this pull request.

I can confirm this works for Windows builds, Linux also built but I did not run the executable.
MacOS resulted in an empty zip and the Web export is not yet supported by Godot 4.0.2, see here godotengine/godot#70796

For anyone who wants a quick summary of the needed changes for this PR:

• change the docker image to adrasteondev/godot-ci:mono-4.0.2 (https://hub.docker.com/r/adrasteondev/godot-ci)
• repace --export with --export-release --headless for all export targets in the .gitlab-ci.yml

[AdrasteonDev]

Thank you for this first review.

With the Godot 4 image, it is also required to use --export "macOS" instead of --export "Mac OSX". I added a comment about that in .gitlab-ci.yml and godot-ci.yml.
I suppose the empty zip you got with macOS is due to that.

[MSchmoecker]

The export target was already changed to macOS.
But after comparing everything with your example project, it turns out codesign/entitlements/disable_library_validation=true must be set in the export_presets.cfg. It is false by default when creating the export present inside Godot.

I merged the Gitlab CI file following #107 and #108. I will see if I need to add commits to adapt the code of the mono version following these PR

[AdrasteonDev]

I added a commit to use the jammy .NET image (to match the ubuntu version used in Dockerfile following #107 and #108).

I also made modifications in these test repositories:

• https://gitlab.com/Adrasteon/test-godot-ci-for-godot-3.5-mono
• https://gitlab.com/Adrasteon/test-godot-ci-for-godot-4-without-mono

I tested the macOS executables: it works (for Godot 3 and 4)

[AdrasteonDev]

Do you know if it will be possible to see this PR merged before the release of Godot 4.1 ? Perhaps I need to wait a little longer for the changes to be verified ?

Ran into what I believe is this issue trying to use the image adrasteondev/godot-ci:mono-4.0.3.

Running in a github ci workflow with something like:

jobs:
  test-dotnet:
    name: Test Dotnet
    runs-on: ubuntu-20.04
    container:
      image: adrasteondev/godot-ci:mono-4.0.3
    steps:
      - name: Check Version
        run: |
            /usr/share/dotnet --version

Fails with /usr/share/dotnet: Permission denied. Attempting to invoke dotnet gives a dotnet not found error. It would be useful to be able to invoke dotnet commands in the container in order to build and run C# tests in CI.

[AdrasteonDev]

Thank you for the test.

Two problems prevented your job from working correctly:

• The dotnet image is based on Ubuntu 22.04 (not Ubuntu 20.04)
• The dotnet command should be used directly (not /usr/share/dotnet)

You can check this repository for a working example.

I have also

• added comments in godot-ci.yml about the Ubuntu version for Godot 4
• created two Gitlab repositories to test the use of the dotnet command with my docker image

I'm curious: What is the state of this PR? Is any help required to put this ahead? Since Godot 4.1.1 is already available, is it reasonable to update this PR to the latest stable?

[AdrasteonDev]

The PR is ready to be merged if maintainers agree. I don't think it's necessary to update the PR.

If necessary you can temporarily use the image I built myself to test this PR: https://hub.docker.com/r/adrasteondev/godot-ci/tags

Why isn't this merged? Csharp+github is really not plug and play right now. Been fiddling with it for a couple of hours, don't even have the solution yet. ( let's hope this is it )

Hi. I've been using your adrasteondev/godot-ci:mono-4.1.2 docker image for running a gitlab pipeline and it works perfectly.
I'm trying to learn how to make a docker image for godot mono exports, would you mind sharing the dockerfile for that docker image?

Barichello/godot-ci image, which yours is based on has a dockerfile available, but after I tried it, it seems to me it is not working properly.

Hi ! Good to see my image is useful :)

You can find it here.

You can also look at the "build-mono" job in this CI file (the variables used by the Dockerfile are defined here).

Thank you, I will give it a spin. :)
