Fatal Error: The system temp directory is not writeable

[Dark-Gizmoa]

After an automativ update with watchtower i get the error message "Baikal Fatal Error: The system temp directory is not writeable" when i try to connect to the WebUI.

Tests i did:

• delete of docker/baikal folder (backup is existent)
• delete of downloaded image
• recreation (checked that i cchown'ed the folders)
• chmod 777 for the complete fodler structure in my docker folder

Error message is still there

[Dark-Gizmoa]

after some testing:

docker exec -it bash

• touch /var/www/baikal/Specific/test.txt; mkdir /var/www/baikal/Specific/test-folder, touch /var/www/baikal/Specific/db/test.txt is possible without error

Docker Folder (inside container) /tmp is owned by root, only read rights for user nginx. After i fiddled a little bit with the rights (chmod 777), Baikal is up and running.

Is it possible to include a script (like /docker-entrypoint.d/40-fix-baikal-file-permissions.sh) to check the tmp folder and set permissions?

Hi @Dark-Gizmoa , that is very strange... can you show me what you see when you run the following command inside the container:

ls -l / | grep tmp

Reason why I'm asking is because when I start a new ckulka/baikal:nginx container, the /tmp directory is owned by root, but also is writable by anyone:

$ docker run --rm -it ckulka/baikal:nginx ls -l / | grep tmp
drwxrwxrwt   2 root root 4096 Jun 12 00:00 tmp

Hi @ckulka,

i think i found the failure:

I changed the image/container folder of docker to an external hdd. Seems that the Access rights werde Set faulty (some correct with r/w some only r) After i chowned the parent folder (in my case /sda/docker_internal/...) everything works fine
