Runtime Exception about docker-grav

[viktor-c]

As pointed by @Braintelligence you can change the ownership of the folder where you installed grav. For this to work your user has to be part of the www-data group. This group has id 33, which appears in this command chown -R 33:33 /srv/doc-user

My workaround was like follows:

1. Go to the Terminal/Konsole in Linux
2. get the id of your running user. id My output looks like this: id
   uid=1000(viktor) gid=1000(viktor) Groups=1000(viktor),...,130(docker)
   we will use 1000 as UID and GUID in the following code. Replace with your ID
3. In your Dockerfile change following lines:

RUN chown www-data:www-data /var/www
USER www-data

with these

ARG UID=1000
ARG GUID=1000
RUN chown www-data:www-data /var/www
RUN useradd -u $UID newuser
RUN usermod -a -G newuser www-data
USER www-data

4. Build and run your grav container

Like this you will add a new user in the grav container. This user has the same ID as your localuser has. Then it will add the group of this user to www-data. As such www-data will have access to your local folder. And so will you.

You have to chown -R 33:33 /srv/doc-user

It's a problem with your user rights.
