# Onboarding / quick start for new administrators
## How to welcome a new administrator
2023-10-23 08:40:35 +00:00
Give them access to the secrets repo. See: https://guide.deuxfleurs.fr/operations/pass/

Basically:
- The new administrator generates a GPG key and publishes it on Gitea
- All existing administrators pull their key and sign it
- An existing administrator reencrypt the keystore with this new key and push it
- The new administrator clone the repo and check that they can decrypt the secrets
- Finally, the new administrator must choose a password to operate over SSH with `./passwd prod rick` where `rick` is the target username

## How to operate a node (connect to Nomad and Consul)
2022-12-22 22:44:00 +00:00
Edit your `~/.ssh/config` file with content such as the following:
```
Host dahlia
HostName dahlia.machine.deuxfleurs.fr
LocalForward 14646 127.0.0.1:4646
LocalForward 8501 127.0.0.1:8501
LocalForward 1389 bottin.service.prod.consul:389
LocalForward 5432 psql-proxy.service.prod.consul:5432
```
Then run the TLS proxy and leave it running:
```
./tlsproxy prod
```
SSH to a production machine (e.g. dahlia) and leave it running:
```
ssh dahlia
```
Finally you should see be able to access the production Nomad and Consul by browsing:
- Consul: http://localhost:8500
- Nomad: http://localhost:4646
