Poky Kas Container

This project is a https://github.com/dimonoff/poky-kas-container that generates a Docker image using the poky-container and kas tools. The generated Docker image can be used for building and testing various software projects.

Background

Poky is a reference distribution of the Yocto Project, an open-source project for building custom Linux-based operating systems. Poky provides a set of tools and recipes for building Linux distributions targeting various hardware architectures and use cases.

Poky-container is a tool for running Poky inside a Docker container, which allows developers to easily set up a consistent and isolated development environment.

KAS is a tool for automating the setup and configuration of Yocto Project builds. It provides a declarative configuration file format and a set of plugins for configuring the build environment.

Build container

bash
./build_image.sh ubuntu-18.04 2.6.2

Deploy container

bash
./deploy_image.sh ubuntu-18.04 2.6.2

Run container

Here a very simple but usable scenario for using the container is described. It is by no means the only way to run the container, but is a great starting point.

• Create a workdir or volume

  • Linux

    The workdir you create will be used for the output created while using the container. For example a user could create a directory using the command

    bash
    mkdir -p /home/myuser/mystuff
    

    It is important that you are the owner of the directory. The owner of the directory is what determines the user id used inside the container. If you are not the owner of the directory, you may not have access to the files the container creates.

    For the rest of the Linux instructions we'll assume the workdir chosen was /home/myuser/mystuff.

  • Windows/Mac

    On Windows or Mac a workdir isn't needed. Instead the volume called myvolume will be used. This volume should have been created when following the instructions at https://github.com/crops/docker-win-mac-docs/wiki.

• The docker command

  • Linux

    Assuming you used the workdir from above, the command to run a container for the first time would be:

    bash
    docker run --rm -it -v /home/myuser/mystuff:/workdir dimonoff/poky-kas-container:ubuntu-20.04-kas-3.2.3 --workdir=/workdir kas shell meta-custom/kas/kas-project.yml
    

    or, if you have SELinux in enforcing mode:

    bash
    docker run --rm -it -v /home/myuser/mystuff:/workdir:Z dimonoff/poky-kas-container:ubuntu-20.04-kas-3.2.3 --workdir=/workdir kas shell meta-custom/kas/kas-project.yml
    

  • Windows/Mac

    bash
    docker run --rm -it -v myvolume:/workdir dimonoff/poky-kas-container:ubuntu-20.04-kas-3.2.3 --workdir=/workdir kas shell meta-custom/kas/kas-projet.yml
    

  Let's discuss the options:

  • --workdir=/workdir: This causes the container to start in the directory specified. This can be any directory in the container. The container will also use the uid and gid of the workdir as the uid and gid of the user in the container.

  This should put you at a prompt similar to:

  bash
  pokyuser@3bbac563cacd:/workdir$
  

  At this point you should be able to follow the same instructions as described
