[[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
~~~

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:
~~~bash
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:
~~~bash
docker exec -it sl-db psql -U (dbusername) simplelogin
~~~
And then run:
~~~bash
UPDATE users SET lifetime = 'TRUE' WHERE EMAIL = '(emailaddress)';
~~~
And \q to exit the db.
