Hi @kernelsam

When you created the runner, did you specify "Ubuntu 22.04 by Arm Limited" as the image? This image has docker installed.

Previously, there was an image called "Base image for Ubuntu 22.04" which did not have docker installed.

Hey @jasonrandrews apologies for the delay on this, you are correct. I deleted the original runner and recreated it. After it shows the new image Ubuntu 22.04 by Arm Limited and I was able to run container jobs. Thanks for the tip!
