##### Docker

```ad-warning
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`
```

Currently running [[Configuring Docker|docker]] containers

```

 

##### Documentation for SimpleLogin

```ad-warning
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

```ad-warning
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](https://github.com/simple-login/app/blob/master/example.env)

Once the change is made, restart the app container:

`docker restart sl-app`

 

##### Force premium subscription for users

Users will be defaulted to the 'Free' plan and asked to subscribe to the premium plan. In order to force users onto the Premium plan, please update the database:

`docker exec -it sl-db psql -U (dbusername) simplelogin`

And then run:

`UPDATE users SET lifetime = 'TRUE' WHERE EMAIL = '(emailaddress)';`

And `\q` to exit the db.
