Issue with permissions

[kn4a-com]

When I try to install a module a get an error that I don't have permissions for writing in the module folder.

Can you guys add change permission to the dockerfile?

I've had quite a lot of issues with permissions (might have induced some on my own...) and resolved them with:
docker exec -ti [containername] bash
then
chown -R www-data:www-data [folders]

However, automatic update of modules still doesn't work, so I'll watch this issue!

@juliencarnot Yeah I already fixed it. Just mentioned it so it can be fixed in future updates.

File change proposal:
master...signofkoen:patch-1
