Requirements

1. You have successfully set up the on boot script described here
2. 05-install-cni-plugins.sh installed

Customization

• You can disable exposing the docker daemon by commenting out the podman service in [01-podman-update.sh](bin.OLD.DONT USE/01-podman-update.sh)

Podman Build Process

• This is a custom-built binary by me. It was cross compiled on Ubuntu-20.04 in WSL2.
• The Makefile needs tweaks. I have supplied the Makefile.patch. Apply it to a fresh podman checkout
• You will need libseccomp-dev:arm64 package installed
• You will need go > 1.12.1 installed
• Setup Cross-Compiler

sudo apt-get install libc6-arm64-cross libc6-dev-arm64-cross binutils-aarch64-linux-gnu libncurses5-dev build-essential bison flex libssl-dev bc gcc-aarch64-linux-gnu

• Compile

make CC="aarch64-linux-gnu-gcc" local-cross

Step

1. Goto the Actions tab and get the latest Podman build and unzip it in your the root of your filesystem, something better is coming but for now that will have to do. You can write a script to automate it, i suggest lots of testing though!
2. Verify Podman version

$ podman version
Version:      3.2.0-dev
API Version:  3.2.0-dev
Go Version:   go1.16.4

Docker Compose

There is no docker-compose binary to run on the UDM yet, so please use docker-compose from a remote system and specify to run on your UDM.

docker-compose -H 10.0.0.1:2375 up

You can also use any regular docker binary and do remote management as well

$ docker -H 10.0.0.1:2375 ps
