To connect, add your private key and SSH into any client or server with
|
|
`ssh ubuntu@PUBLIC_IP`. You can test the integrity of the cluster by running:
|
|
|
|
$ consul members
|
|
$ nomad server-members
|
|
$ nomad node-status
|
|
|
|
If you see an error message like the following when running any of the above
|
|
commands, it usually indicates that the configuration script has not finished
|
|
executing:
|
|
|
|
"Error querying servers: Get http://127.0.0.1:4646/v1/agent/members: dial tcp
|
|
127.0.0.1:4646: getsockopt: connection refused"
|
|
|
|
Simply wait a few seconds and rerun the command if this occurs.

The Nomad UI can be accessed at http://PUBLIC_IP:4646/ui.
