Run TeamCity agents in your Kubernetes cluster

README.md

How to run TeamCity agents in your Kubernetes cluster

For typical CI/CD tasks that don't require Docker daemon access, use the agent.yml pod sepc.

For CI/CD jobs that need Docker daemon to build Docker images, use the privileged-agent.yml pod spec.

Notes

Make sure you are running TeamCity server version >= 2020.1 or have the Kubernetes support plugin installed.

Create a new cloud profile in your cloud profiles settings.

For the agent image configuration popup, choose "Use custom pod template", then fill in content of the YAML file below that matches your need.

You might want to create two Agent pool and two Cloud Profiles, for privileged and unprivileged agents respectively.

agent.yml

apiVersion: v1
kind: Pod
metadata:
  name: teamcity-build-agent
spec:
  containers:
  - name: teamcity-build-agent
    image: jetbrains/teamcity-agent:2020.1 # Change this version tag with your server.
    imagePullPolicy: IfNotPresent

privileged-agent.yml

apiVersion: v1
kind: Pod
metadata:
  name: teamcity-build-agent
spec:
  containers:
  - name: teamcity-build-agent
    image: jetbrains/teamcity-agent:2020.1 # Change this version tag with your server.
    imagePullPolicy: IfNotPresent
    env:
    - name: DOCKER_IN_DOCKER
      value: start
    securityContext:
      privileged: true
      runAsUser: 0

Is there any way to autoscale it and authorize the agent automatically ?
