How to edit theme style in docker?

~# docker exec -it 9f3678b6218f /bin/bash OCI runtime exec failed: exec failed: unable to start container process: exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown

How can this be solved?

Try docker-compose exec lemmy-ui sh, the container might not have bash. Also, any changes made this way will be gone after restart.

I want to map the /app/dist/assets/css/themes directory in the container to the host lemmy directory. Thereby, the theme file in the container can be modified on the host machine. Added the following code in docker-compose.yml:

 volumes:
   - ./volumes/lemmy-ui:/app/dist/assets/css/themes

After running the instance, no files appear in the host lemmy/volumes/lemmy-ui directory.

So, what should I do to map the /app/dist/assets/css/themes directory in the container to the host lemmy directory? ? ?

This is not the right way to develop themes, you should use the preconfigured themes folder.

sudo docker exec -it postgres psql -U postgres ？ Not correct?

[–] nutomic@lemmy.ml 1 points 2 years ago (1 children)

Dont know, you will see if it works or not. I always use the docker-compose commands.

What is the docker-compose command?

[–] nutomic@lemmy.ml 1 points 2 years ago (1 children)

docker-compose exec postgres psql -U lemmy

[–] aihao@lemmy.ml 1 points 2 years ago* (last edited 2 years ago) (1 children)

I change the database name to lemmyok in docker-compose.yml and lemmy.hjson, and use the command "docker-compose exec postgres psql -U lemmyok" and get " psql: error: FATAL: role "lemmyok" does not exist ",can't enter PG.

If I use the command docker-compose exec postgres psql -U lemmy without changing the database name, I can enter PG normally.

Am I doing something wrong?

What should be the correct solution?

-U is for the postgres user, not the database. you can pass that with -d
