### Docker container names resolution
-If you want to have your container names resolved by netdata it needs to have access to docker group. To achive that just add environment variable `PGID=999` to netdata container, where `999` is a docker group id from your host. This number can be found by running:
-```bash
-grep docker /etc/group | cut -d ':' -f 3
-```
+If you want to have your container names resolved by netdata, you need to do two things:
+1) Make netdata user be part of the group that owns the socket.
+ To achieve that just add environment variable `PGID=[GROUP NUMBER]` to the netdata container,
+ where `[GROUP NUMBER]` is practically the group id of the group assigned to the docker socket, on your host.
+ This group number can be found by running the following (if socket group ownership is docker):
+ ```bash
+ grep docker /etc/group | cut -d ':' -f 3
+ ```
+
+2) Change docker socket access level to read/write like so:
+ from
+ ```
+ /var/run/docker.sock:/var/run/docker.sock:ro
+ ```
+
+ change to
+ ```
+ /var/run/docker.sock:/var/run/docker.sock:rw
+ ```
+
+**Important Note**: You should seriously consider the necessity of activating this option,
+as it grants to the netdata user access to the privileged socket connection of docker service
### Pass command line options to Netdata
