code-server: "Insufficient permission" error on save

I think @DavisAre’s solution seems like the best path forward here, typically when I’ve needed to edit files from inside a container this has been the recommended approach. The alternative seems to be changing host file permissions which isn’t great…

I will note though that in my case when I try to run it with a forwarded user I get:

ERROR { Error: EACCES: permission denied, mkdir '/.cache'
  [stack]: 'Error: EACCES: permission denied, mkdir \'/.cache\'',
  [message]: 'EACCES: permission denied, mkdir \'/.cache\'',
  errno: -13,
  code: 'EACCES',
  syscall: 'mkdir',
  path: '/.cache' }
free(): invalid pointer

services:
  visual:
    image: codercom/code-server:latest
    restart: always
    user: "0:0"

It’s not pretty but it solves the issue.

I’ve created an image of my own which uses the coder binary + fixuid and it is working great! I combine that with docker compose commands and I’m able to spin up lots of coder instances for myself and colleagues. Image at https://hub.docker.com/r/acondura/code-server.

I already logged a fix but its stuck at pending for god knows how long.

#679

Ok, I circumvented this by passing -u variables and running as current user. In my case - root. You can also specify other user’s/group’s IDs like -u 1000:1000 docker run -it -p 127.0.0.1:8443:8443 -u $(id -u):$(id -g) -v "${PWD}:/home/coder/project" codercom/code-server:1.621 --allow-http

Might not be the best approach but may be helpful for someone as quick workaround without dealing with directory, file ownership.

Setting wider access settings on those files/directories worked for me - from 664 to 666.

If access rights are not the case, you can use chmod o+w file or chmod o+w -R dir on whole directory if needed. However, mind that this is not the safe solution.

I believe it’s due to trying to edit files by user ‘docker’ or something similar (since we’re operating from inside of the container) and it is not issue with code-server itself.
