2. Configure vault variables
|
|
|
|
```bash
|
|
vault kv put secret/k3os-alpha.dnet/agent token=<token> server_url=<server_url>
|
|
```
|
|
|
|
3. Template your server or agent
|
|
|
|
```bash
|
|
# server
|
|
HOSTNAME=<HOSTNAME>; yq e ".hostname = \"$HOSTNAME\" | .k3os.token = \"$(vault kv get -field=token secret/k3os-alpha.dnet/agent)\" | .k3os.server_url = \"$(vault kv get -field=server_url secret/k3os-alpha.dnet/agent)\"" k3os_server.yaml > templates/$HOSTNAME.yaml
|
|
|
|
# agent
|
|
HOSTNAME=<HOSTNAME>; yq e ".hostname = \"$HOSTNAME\" | .k3os.token = \"$(vault kv get -field=token secret/k3os-alpha.dnet/agent)\" | .k3os.server_url = \"$(vault kv get -field=server_url secret/k3os-alpha.dnet/agent)\"" k3os_agent.yaml > templates/$HOSTNAME.yaml
|
|
```
|
|
|
|
4. Save the template to /var/lib/rancher/k3os/config.yaml
