To make the setup work, you need to replace a few placeholders:
|
||||
|
||||
- Replace `<PXE_SERVER_IP>` with your PXE server ip address (e.g. 10.20.30.242)
|
||||
- Replace `<MASTER_SERVER_IP>` with the kubernetes master ip address (e.g. 10.20.30.40)
|
||||
- If you run a private docker registry, replace `rdocker.example.com` with your docker registry dns name.
|
||||
- If you use a proxy, replace `rproxy.example.com` with your proxy server (and port)
|
||||
- Add your own SSH public key(s) to the cloud config at the end
