OCI Bundle Generator (BundleGen)

RDK Component to generate extended OCI bundle*'s from OCI Images, ready to be run by Dobby

Environment Setup

You will need Python >=3.7 installed and configured. You will also require some project specific dependencies and OCI tools.

A Fedora 32 Vagrantfile is included to provide a ready-to-use environment. Otherwise follow the steps later in this document to set up your own Fedora/Ubuntu environment.

Quick Start

Start the Vagrant VM and SSH in.

$ vagrant up
$ vagrant ssh

Activate the Python venv

$ cd ~/bundlegen
$ source .venv/bin/activate

Run BundleGen:

If using an image generated by the DAC SDK, then run

$ bundlegen generate --platform <platform-name> <img-url> <output-dir>

If using an image from a generic OCI registry (not built by the DAC SDK), then run

$ bundlegen generate --platform <platform-name> --appmetadata <path-to-app-metadata> <img-url> <output-dir>

Note the image URL should be in the form docker://image-url. If the image is on the Docker Hub, the full URL can be omitted - e.g docker://hello-world.

See the docs directory for more detailed documentation.

Docker

A dockerfile is included that can be used to run BundleGen as an alternative to Vagrant. See the docker directory for instructions on how to use.

Test Scripts

Test scripts are included for reference platforms to speed up the generation and installation process.

Install and test already generated bundle:

./test/testapp.sh 192.168.1.124 rpi-dac-image-wayland-egl-test.tar.gz

Generate bundle for Raspberry Pi

./test/build_and_test_on_rpi.sh 192.168.1.124 dac-image-wayland-egl-test.tar

Development

These steps only apply if you're not using the included Vagrantfile

For development, you will need Python >=3.7 installed and configured. Once installed, then install project specific dependencies.

Fedora 32

It's easier to work in Fedora as the OCI tooling is already available

# Install dependencies
$ sudo dnf upgrade -y
$ sudo dnf install -y make git skopeo go go-md2man
# Install Go
$ mkdir -p $HOME/go
$ echo 'export GOPATH=$HOME/go' >> $HOME/.bashrc
$ source $HOME/.bashrc
# Build/install umoci
$ go get -d github.com/opencontainers/umoci
$ cd $GOPATH/src/github.com/opencontainers/umoci/
$ make
$ sudo make install

Ubuntu >=18.04

It's also possible to build on Ubuntu. Note Skopeo only publishes packages for Ubuntu 18.04 or newer. It may be possible to build skopeo from source on older distributions, see https://github.com/containers/skopeo/blob/master/install.md

# Install dependencies
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install -y make git go-md2man
# Install Go 1.13
$ wget https://dl.google.com/go/go1.13.12.linux-amd64.tar.gz
$ tar -xvf go1.13.12.linux-amd64.tar.gz
$ sudo mv go /usr/local
$ mkdir -p $HOME/go
$ echo 'export GOPATH=$HOME/go' >> $HOME/.bashrc
$ echo 'export GOROOT=/usr/local/go' >> $HOME/.bashrc
$ echo 'export PATH=$GOPATH/bin:$GOROOT/bin:$PATH' >> $HOME/.bashrc
$ source $HOME/.bashrc
# Build/install umoci
$ go get -d github.com/opencontainers/umoci
$ cd $GOPATH/src/github.com/opencontainers/umoci/
$ make
$ sudo make install
# Install skopeo
$ . /etc/os-release
$ sudo sh -c "echo 'deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/x${NAME}_${VERSION_ID}/ /' > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list"
$ wget -nv https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/x${NAME}_${VERSION_ID}/Release.key -O- | sudo apt-key add -
$ sudo apt update && sudo apt install skopeo
