Create a container

It is up to developers to decide what container to create.

Ubuntu 22.04 (Preferred for Mickledore)

sudo docker build -t yocto-build:v1 - < $(pwd)/docker/Dockerfile-22.04

Ubuntu 20.04 (Preferred for Kirkstone)

sudo docker build -t yocto-build:v1 - < $(pwd)/docker/Dockerfile-20.04

Ubuntu 18.04 (Optional)

sudo docker build -t yocto-build:v1 - < $(pwd)/docker/Dockerfile-18.04

Execute docker

sudo docker run --interactive --tty  --privileged --volume $(pwd)/work:/work yocto-build:v1

Create internal work folder:

sudo mkdir in-work
sudo chown $USER:$USER in-work
cd in-work
