How can i run termux from docker in CI/CD

[John4650-hub]

how can i run the termux-docker image in something like github actions or circleci.
I have tried but in both cases i get incompatibility issues.

I am working on a project in which i need to install alot of packages from the termux repo, and my device is kinda running short of storage space, so only option is this.
The files in the project are mainly C++ files, and a few in Rust.
Is it possible to build a custom the image with the required packages installed such that i save time when compiling.

Is there a way to also build the termux-only docker image using a Dockerfile with the the packages i need for my project installed. So that i just pull from dockerhub and use in my other worflows.

See the https://github.com/termux/termux-docker repo.

@twaik, I am having issues here's the output

Run docker run --rm termux/termux-docker:arm bash -c "apt update && apt install -yq clang"

You did not setup binfmt misc...

Please read the README file in the termux-docker project. "If architecture is not compatible with host, the additional setup will be needed. Read this document further to learn how you can run containers of incompatible CPU architecture."

The container started but the following information was displayed

WARNING: The requested image's platform (linux/arm/v7) does not match the detected host platform (linux/amd64/v3) and no specific platform was requested
error getting old personality value: Operation not permitted
libc: error getting old personality value: Operation not permitted
Aborted (core dumped)
[!] Container is running as non-root, unable to start dnsmasq. DNS will be unavailable.
error getting old personality value: Operation not permitted
libc: error getting old personality value: Operation not permitted

The Run Termux step won't proceed as the container doesn't stop.
This how the workflow step looks like

- name: Run Termux
      run: |
        docker run --rm --privileged aptman/qus -s -- -p aarch64 arm
        docker run --rm termux/termux-docker:arm bash -c "apt update && apt install -yq clang && clang -help > foo.txt"
        docker ps -q | xargs -r docker stop

    - name: Show foo
      run: cat foo.txt

[John4650-hub]

This worked

name: Set up QEMU for aarch64 emulation
      run: docker run --rm --privileged aptman/qus -s -- -p aarch64 arm

    - name: Run Termux
      run: |
        docker run \
          --privileged \
          --name termux-docker-arm \
          termux/termux-docker:arm \
          bash -c "uname -a" > /home/runner/work/learn-docker/learn-docker/foo.txt
        docker stop termux-docker-arm

    - name: Cleanup Docker
      if: always()
      run: |
        docker ps -aq --filter "name=termux-arm" | xargs -r docker stop
        docker ps -aq --filter "name=termux-arm" | xargs -r docker rm
    - run: cat foo.txt

@twaik
After installing clang, i tried running clang --help but instead got some error. I have search but no solution found

CANNOT LINK EXECUTABLE "/data/data/com.termux/files/usr/bin/clang": cannot locate symbol "_ZNSt6__ndk122__libcpp_verbose_abortEPKcz" referenced by "/data/data/com.termux/files/usr/bin/clang-19"...

pkg up...

[John4650-hub]

Let me try it, I had used apt-get update && apt-get upgrade

[John4650-hub]

@twaik , error still comes up. Clang installs without any warnings but when i try running it thats when it comes up.
