dockeragent

build a docker image that will run as self-hosted Azure pipeline agent on kubernetes

Using the environment file we can create a ConfigMap with the command

kubectl create cm azure-agent-config --from-env-file=var.env 

With a Kubernetes Deployment we can run as many copies of the agent as we need, injecting our ConfigMap values along with an AZ_AGENT_NAME into the pod environments.

Or, create a secret with following command.

kubectl create secret generic azdevops \
  --from-literal=AZP_URL=https://dev.azure.com/yourOrg \
  --from-literal=AZP_TOKEN=YourPAT \
  --from-literal=AZP_POOL=NameOfYourPool
kubectl apply -f deploy-dockeragent.yaml
