I'd like to configure my docker daemon. To do so, I have to modify the daemon.json file, but unfortunatelly, it's on a filesystem that is mounted read-only;
root@shinwey:/snap/docker/current/config# ls -ltr total 1 -rw-r--r-- 1 root root 72 Jun 8 22:18 daemon.json root@shinwey:/snap/docker/current/config# touch daemon.json touch: cannot touch 'daemon.json': Read-only file system root@shinwey:/snap/docker/current/config# df . Filesystem 1K-blocks Used Available Use% Mounted on /dev/loop3 128896 128896 0 100% /snap/docker/471 I tried to play with "snap get docker", as this command deals with configuration, with no success;
root@shinwey:/snap/docker/current/config# snap get docker error: snap "docker" has no configuration Is there any specific "snap" command to update an application configuration ?
Any help would be greatly appreciated

mentions that the daemon.json file should be in this folder :
/var/snap/docker/current/etc/docker/daemon.json
or
/var/snap/docker/current/config/daemon.json
to take into account the changes you then need to
sudo snap restart docker
