petalinux container

A simple docker abstraction script to make building Petalinux as portable as possible. This script helps to enable a "portable" Petalinux development environment by providing a "pre-built" ubuntu image.

Script Dependencies

• python3
• http.server (pip3 install http.server)
• expect (sudo apt install expect)

Compatibility

The script initially requires building of the included Dockerfile and downloading the desired Petalinux installer. After a successful initial build, the image can then be pushed to DockerHub for easy reuse.

Usage

1. Check out this repository to the folder you wish to execute Petalinux builds in
2. Download the Petalinux installer of choice then place the .run file in a directory called installers
3. Define your container-params file based off of container-params.sample
4. Always run ./container from the directory you wish to store your Petalinux build outputs.

The script creates a folder in the directory it is run from named yocto it then configures the container to run with:

• Your user account
• Your /home folder
