How to set custom uid and guid ?

[kopax]

I am reading at https://github.com/docker-library/ghost/blob/3332df18c9d6a11ba0d227b667ba27733a44fafe/3/alpine/Dockerfile and can't find a way to add a custom UID and GID for the container.

Apparently this feature was added before #53

How can I set the custom uid and guid in the official docker ghost image ?

The PR you linked was closed, not merged. But with the merge of #54 You'd use the --user option

This is implemented in the same way we've supported arbitrary values for docker run --user in many other images.

Hi @wglambert and thank you for your quick reply.

Perhaps you can enlight me, my goal is pretty simple : I want to create an environment of development for ghost with a forked casper theme for docker .

I have followed this recent tutorial : https://www.grottedubarbu.fr/ghost-docker-theme-dev/ (french) to setup a development environment. (I couldn't find a recent resource for ghost 3.0 other than this one)

Within the container, the UID used if I dont set the --user option is 1000, while my own UID is 10000, for editing those files in IntelliJ, I must set the UID within the container to 10000

My docker-compose.yml look like this:

docker-compose

version: '3'
services:
  blog-kop-ax:
    container_name: dev-blog-kop-ax
    image: ghost:3.35.5-alpine
    ports:
      - "2368:2368"
    restart: unless-stopped
    user: "10000:10000"
    volumes:
      - ./content:/var/lib/ghost/content
      - ./themes/blog-kopax:/var/lib/ghost/content/themes/blog-kopax
    environment:
      - NODE_ENV=development
    networks:
      - lan

  node-tools-init:
    image: node:12-buster-slim
    container_name: ghost-tools-init
    restart: on-failure
    user: "10000:10000"
    volumes:
      - ./themes/blog-kopax:/home/node/app/blog-kopax
    working_dir: /home/node/app/blog-kopax
    command: 'yarn install'
    networks:
      - lan


  node-tools:
    image: node:12-buster-slim
    container_name: ghost-tools
    restart: unless-stopped
    user: "10000:10000"
    volumes:
      - ./themes/blog-kopax:/home/node/app/blog-kopax
    working_dir: /home/node/app/blog-kopax
    command: 'yarn dev'
    network_mode: none

networks:
  lan:

The themes/blog-kopax directory is a symlink of a cloned repository of TryGhost/Casper themes

As you expect, with --user 10000, I can see themes/blog-kopax directory using the right folder permissions (10000), but the content folder is always created for root user (while I expected it to be created for 10000).

Also, I expected the content mounted volumes to be created on first run. since my container fail at start, I can see that content/themes/blog-kopax is also created and empty, but also duplicate of theme/blog-kopax (the correct theme directory).

This is the log:

This is my setup:

There's obviously something wrong with the permissions despite --user being set.

How would you recommend to setup a development environment for docker and using a forked Casper theme?

[wglambert]

Hmm, looks like running as an arbitrary user no longer works
Using the test example from #54 (comment) :

$ docker run -it --rm --user "$RANDOM:$RANDOM" --name ghost ghost
tar: apps: Cannot mkdir: Permission denied
tar: Exiting with failure status due to previous errors

$ docker run -it --rm --user "$RANDOM:$RANDOM" --name ghost ghost:alpine
tar: can't make dir apps: Permission denied
tar: can't make dir data: Permission denied
tar: can't make dir images: Permission denied
tar: can't make dir logs: Permission denied
tar: can't make dir settings: Permission denied
tar: can't make dir themes: Permission denied
tar: can't create directory 'themes': Permission denied
tar: can't create symlink 'themes/casper' to '/var/lib/ghost/current/content/themes/casper'

$ docker run -it --rm --user "$RANDOM:$RANDOM" --name ghost ghost:2
tar: apps: Cannot mkdir: Permission denied
tar: Exiting with failure status due to previous errors

[tianon]

Great catch -- not sure how #54 ever worked (although it was probably some bug in my Gentoo system at the time).

Fix is up at #237 👍

[kopax]

Great, how can I pull this fix from docker hub ?

How about this error tar: can't create symlink 'themes/casper' to '/var/lib/ghost/current/content/themes/casper' ? I named my theme differently, should I rename casper ?

[tianon]

It's not on Docker Hub yet, but you can build it locally to test with something like docker build --pull https://github.com/docker-library/ghost.git#refs/pull/237/merge:3/alpine (add --tag if you want to tag the image to make it easier to use/test in your docker-compose.yml).

[kopax]

Thanks for your quick reply, I have tried with --tag but it seems that this options is not available for docker build .

I have just tried with:

$ docker build --pull https://github.com/docker-library/ghost.git#refs/pull/237/merge:3/alpine 
Successfully built 3dfdd3da7248
$ docker tag 3dfdd3da7248 -t custom-ghost
"docker tag" requires exactly 2 arguments.

I'll keep looking for the right CMD.

Anyone, how about my question regarding the casper theme error ? Why does the mounted renamed theme still require a casper to be set?

[kopax]

Hi all, I have tried with the latest image and I still have some permissions issues :

EDIT

I was able to have a working development environment only after doing a sudo chown -R 10000:10000 themes and sudo chown -R 10000:10000 content

I want to add my theme in a docker image, I can't find any information, how can I add my default theme using Dockerfile ?
