Custom Runner Image with Gcloud preinstalled

[brconnell4]

I want to have Gcloud preinstalled on my RunnerDeployments so I can split up tasks into jobs. I tried the following

FROM summerwind/actions-runner:v2.299.1-ubuntu-20.04

# Set user to root (required to install packages)
USER root

# Add Google Cloud SDK repo
RUN echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] https://packages.cloud.google.com/apt cloud-sdk main" | tee -a /etc/apt/sources.list.d/google-cloud-sdk.list && \
    apt-get install -y apt-transport-https ca-certificates gnupg && \
    curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key --keyring /usr/share/keyrings/cloud.google.gpg add -

# Update and install packages
RUN apt-get update -y && apt-get install -y google-cloud-sdk

# Switch back to runner user
USER runner

And then updated my manifest

apiVersion: actions.summerwind.dev/v1alpha1
kind: RunnerDeployment
metadata:
name: actions-runner
namespace: actions-runner-system
spec:
template:
spec:
repository: ***
image: ***
imagePullPolicy: Always
envFrom:
- secretRef:
name: actions-runner-secrets

The image is downloaded successfully but the pods just continously crashloop. Here are the errors from the pods

Not sure what I am doing wrong

By any chance did you build your custom runner Docker image on an Apple silicon Mac? I believe I ran into this same error as well, building my custom image on an Apple silicon MacBook Pro and trying to run in an x86 k8s cluster. What fixed it for me was to add the --platform=linux/amd64 flag to my docker build command.
