Self-Hosted Stock-Knative on KinD Runners

Setup

1. Install Ansible on your local machine:
   https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#installing-ansible-on-specific-operating-systems
2. Start a new experiment on Cloudlab:
   • Profile: small-lan
   • OS Image: UBUNTU 18.04
   • Physical Node Type: rs440 (others are probably fine too)
   • (Under "Advanced") Temp Filesystem Max Space: Selected
3. On your local machine, use Ansible to setup the remote host:

   ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, setup-host.yaml

4. On your local machine, use Ansible to create a stock-Knative runner on KinD on the remote host:

   GH_ACCESS_TOKEN=... ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, create-runner.yaml

   • GH_ACCESS_TOKEN environment variable shall be set to your GitHub access token.

You may call the fourth step as many times as you like. To create N=10 runners, execute the following on bash:

for run in {1..10}; do GH_ACCESS_TOKEN=... ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, create-runner.yaml; done

Deleting All Runners

On your local machine, use Ansible to delete all runners:

GH_ACCESS_TOKEN=... ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, delete-runners.yaml

Delete All Runners and Start New N Runners

GH_ACCESS_TOKEN=... ./scripts/self-hosted-kind/easy-recreate.sh REMOTE_HOSTNAME N

Restarting the Host

1. On your local machine, use Ansible to delete all runners:

   GH_ACCESS_TOKEN=... ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, delete-runners.yaml

2. Restart the remote host:

   sudo shutdown --reboot now

3. On your local machine, use Ansible to recreate runners (N=10) on the remote host:

   for run in {1..10}; do GH_ACCESS_TOKEN=... ansible-playbook -u YOUR_SSH_USERNAME -i REMOTE_HOSTNAME, create-runner.yaml; done
