Upgrade Remediate on online nodes

Upgrading to a new version of Puppet Remediate on a node with internet access can be done with a few simple commands.

To upgrade from Remediate 1.1.0 to Remediate 1.2.1:

Run the following command from the folder where your docker-compose.yml file is located:
```
docker-compose run remediate stop
```
Remove the oauth_client.json file:
```
docker secret rm oauth_client.json
```
Finally, run the Remediate update command:
```
docker-compose run remediate update
```

What to do next

Remember: After you update Remediate, any existing discovered data is lost. You must wait for the next scheduled data discovery run completes to see data in the UI. Alternatively, click Discover All on the Manage Sources page to start a discovery run manually.
