Write permission is needed for log files. The pod in which RAP runs defines a volume called
log in which the log files are written. This means that the files are stored outside the container on the machine that hosts the docker platform.
You have a host computer in which the docker platform runs. (In deploying RAP3 for the OUNL that would be the machine with domain name
rap.cs.ou.nl). To avoid permission errors (and the use of
sudo), add your user to the
docker group. Read more.
