1. Copy orchestra SSH key to the servers to be managed (you can use <span title="`orchestra@panel:~ ssh-copy-id root@server.address`">`ssh-copy-id`</span>: ), then Add the servers to be managed by orchestra into the servers section `/admin/orchestration/servers`, then copy orchestra's SSH pubkey to them
2. Now configure service by service (domains, databases, webapps, websites...): 1. Copy orchestra SSH key to the servers to be managed, you can use `ssh-copy-id`:
1. Add the route through `/admin/orchestration/route/` ```bash
2. Check and configure related settings on `/admin/settings/setting/` orchestra@panel:~ ssh-copy-id root@server.address
3. Configure related resources if needed `/resources/resource/`, like Account Disc limit and traffic. ```
3. Test that everything works by creating and deleting services Then add the servers to orchestra using the web interface `/admin/orchestration/servers`, check that the SSH connection is working and Orchestra can report the uptime of the servers.
2. Now configure service by service (domains, databases, webapps, websites, ...):
1. Add the route via `/admin/orchestration/route/`
2. Configure related settings on `/admin/settings/setting/`
3. If required, configure related resources like Account disc limit, VPS traffic, etc `/resources/resource/`
3. Test that everything works as expected by creating and deleting service instances
