1. To build the container locally from the directory containing the Dockerfile, run the following command:

$ docker build

2. However, there is no need to build it locally as the container is automatically built on the Docker registry: https://hub.docker.com/r/yoctocookbook2ndedition/docker-yocto-builder

First create an empty folder owned by a user with the same uid and gid that the build user inside the container:

$ sudo install -o 1000 -g 1000 -d /opt/yocto/docker-yocto-builder

And change inside the new directory:

$ cd /opt/yocto/docker-yocto-builder

To run the container and map its /home/build folder to the current directory, type:

$ docker run -it --rm -v $PWD:/home/build yoctocookbook2ndedition/docker-yocto-builder  

Where:

• • -it instructs Docker to keep stdin open even when the container is not attached and assign a pseudo-tty to the interactive shell
  • --rm instructs Docker to remove the container on exit
  • -v maps the host current directory as the /home/build container volume

3. We can now instruct the container to build a Poky project with:

build@container$ source /opt/yocto/poky/oe-init-build-env qemuarm build@container$ MACHINE=qemuarm bitbake core-image-minimal

4. To build a FSL community BSP project, you need to map the /opt/yocto/fsl-community-bsp/build container directory with the current directory as the setup-environment script only works when the build directory is under the installation folder:

$ docker run -it --rm -v $PWD:/opt/yocto/fsl-community-bsp/build yoctocookbook2ndedition/docker-yocto-builder  

5. Then we can run the following command inside the container to create a new project and start a build:

build@container$ cd /opt/yocto/fsl-community-bsp/
build@container$ mkdir -p wandboard
build@container$ MACHINE=wandboard DISTRO=poky source setup-environment build
build@container$ bitbake core-image-minimal
