##### 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:
|
|
|
|
~~~bash
|
|
sudo usermod -aG docker (username)
|
|
~~~
|
|
|
|
Potentially, the Docker group needs to be defined:
|
|
|
|
~~~bash
|
|
sudo groupadd docker
|
|
~~~
|
|
```
|
|
|
|
Currently running [[Configuring Docker|docker]] containers

#### 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:
|
|
|
|
```ad-path
|
|
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:
|
|
|
|
```ad-command
|
|
~~~bash
|
|
docker restart sl-app
|
|
~~~
|
|
```
|
|
|
|

|

|
