Poky Container

This repo is to create an image that is able to run bitbake/poky. The main difference between it and https://github.com/crops/yocto-dockerfiles is that it has helpers to create users and groups within the container. This is so that the output generated in the container will be readable by the user on the host.

The instructions will be slightly different depending on whether Linux, Windows or Mac is used. There are setup instructions for using Windows/Mac at https://github.com/crops/docker-win-mac-docs/wiki. When referring to Windows/Mac in the rest of the document, it is assumed the instructions at https://github.com/crops/docker-win-mac-docs/wiki were followed.

Running the 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

    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:

    docker run --rm -it -v /home/myuser/mystuff:/workdir crops/poky --workdir=/workdir
    

    or, if you have SELinux in enforcing mode:

    docker run --rm -it -v /home/myuser/mystuff:/workdir:Z crops/poky --workdir=/workdir
    

  • Windows/Mac

    docker run --rm -it -v myvolume:/workdir crops/poky --workdir=/workdir
    

  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:

  pokyuser@3bbac563cacd:/workdir$
  

  At this point you should be able to follow the same instructions as described in https://docs.yoctoproject.org/brief-yoctoprojectqs/index.html
