title: Docker for non root users
[[Docker config|docker]] predominantly works for the root user. In order to let non-root users instruct Docker, users need to be added to the Docker group:

`sudo usermod -aG docker (username)`

Potentially, the Docker group needs to be defined:

`sudo groupadd docker`

Documentation for SimpleLogin
title: Troubleshooting SimpleLogin
Troubleshooting for [SimpleLogin](https://github.com/simple-login/app) and its parametrisation can be found [here](https://github.com/simple-login/app/blob/master/docs/troubleshooting.md) and [here](https://github.com/simple-login/app/blob/master/example.env)

 

CertBot
title: Troubleshooting CertBot
Running and troubleshooting for CertBot can be found [here](https://certbot.eff.org/docs/install.html)

 

Service management

The service itself does not require particular management as all features are embedded in the client interface running from the docker container 'sl-app', including user management. Parameters can only be amended through the config file under the root user:

sudo vim ~/simplelogin.env

Sample configs can be found here

Once the change is made, restart the app container:

docker restart sl-app
