[kaykhan]

If i want to have cli tools avaialble to use in the github runner. What is the best way to do this?

Building custom docker image from base actions-runner image & use it when launching ephemeral runners using ARC
something like

FROM ghcr.io/actions/actions-runner:latest

# Install required debian packages
RUN sudo apt-get update \
    && sudo apt-get install -y openssh-client zip git file jq curl \
    && sudo apt-get upgrade -y

Is it possible to set a custom script .sh file to run?
