Permission denied creating first template

I know its been posted before but I cant find the solution. My friend got Coder working on our Ubuntu 22.04 with docker-compose. The error is:

Error: Error pinging Docker server: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied
on main.tf line 21, in provider "docker":
  21: provider "docker" {

Error: Error pinging Docker server: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied
on main.tf line 21, in provider "docker":
  21: provider "docker" {

I tried creating a "coder" user and adding it to the docker group without success. I restarted the Coder container, do I need to restart Docker itself too?

Solution:

uncomment the group_add line and change 998 to the GID of your Docker group

FIXED! For others, this did the trick for me ❗Use 660 instead of 666 ❗

Moondog•2y ago

I just tried this for myself and no dice. Is there a chance you did some other stuff?

FuglenOP•2y ago

There might be, but what error do you get?

Moondog•2y ago

Pretty much what you got but managed to figure out it's was a typo in the docker compose file. I type 997 instead of 998 for the docker group. All sorted. Can't believe I spent a few hours on something like that 😅

Immuc•6mo ago

Thank you!

FuglenOP•6mo ago

I'm glad my update helped you, I hope you didn't use hours on this error like us? 😂

Immuc•6mo ago

No i just searched for permission denied here in help xD probably saved me that exact time haha

Phorcys•6mo ago

oh no that is really bad in terms of security, this is giving access to the Docker socket to all the users of your system you should revert the permissions back to 660 and instead edit the Docker Compose file for Coder to make it run within the Docker group

FuglenOP•6mo ago

At that time I didn't care much and I no longer use Docker 😅 Updated my fix 🙂

uncomment the group_add line and change 998 to the GID of your Docker group

Phorcys•6mo ago

@Moondog @Jackson, you will also want to revert this permission change as it is very unsafe

Nice spotted, sorry for the inconvenience guys 🙈
