I have a problem with creating new files in mounted docker volume.
Firstly after installation docker i added my user to docker group.
sudo usermod -aG docker $USER
Created as my $USER folder:
mkdir -p /srv/redis
And starting container:
docker run -d -v /srv/redis:/data --name myredis redis
when i want to create file in /srv/redis as a user which created container I have a problem with access.
mkdir /srv/redis/redisTest
mkdir: cannot create directory ‘/srv/redis/redisTest’: Permission denied
I tried to search in other threads but i didn't find appropriate solution.
The question title does not reflect the real problem in my opinion.
mkdir /srv/redis/redisTest
mkdir: cannot create directory ‘/srv/redis/redisTest’: Permission denied
This problem occurs very likely because when you run:
docker run -d -v /srv/redis:/data --name myredis redis
the directory /srv/redis ownership changes to root. You can check that by
ls -lah /srv/redis
This is normal consequence of mounting external directory to docker. To regain access you have to run
sudo chown -R $USER /srv/redis
