docker-yocto

About

This repo contains docker image I use for building the yocto images.

I use the script yocto-build.sh to switch yocto building environment so I can use docker to build the Yocto project instad of install a ubuntu as VM.

Setting up

First download the yocto-build.sh as ~/bin/yocto-build

mkdir -p ~/bin
curl https://raw.githubusercontent.com/coldnew/docker-yocto/master/yocto-build.sh > ~/bin/yocto-build
chmod +x ~/bin/yocto-build

Add following line to the ~/.bashrc file to ensure that the ~/bin folder is in you PATH variable.

export PATH=~/bin:$PATH

Basic Usage

First time to use the yocto-build command, you need to tell it where is the workdir we build the yocto image.

For example, if I want to build yocto at /home/coldnew/poky then:

yocto-build --workdir /home/coldnew/poky

After this command, we'll create a container named yocto-build, which is the environment we used to build the yocto image. Now you'll find your current shell is switch to the container and the /home/coldnew/poky is mounted to /yocto.

Spawn a new shell

If you want to spawn a new shell in another terminal, you can use

yocto-build --shell

This will spawn a new shell if you already specify a workdir.

Remove the container

This script only support ONLY ONE CONTAINER, so If you want to change the workdir, you should remove it first, remove a container is easy, just use following command:

yocto-build --rm

Then you can setup a new workdir you want.

Upgrade script

Upgrade this script is easy, just type

yocto-build --upgrade

Pull new docker container

To pull new docker image, just type

yocto-build --pull
