tldr; Running this command after every restart fixes the problems:

docker exec -it wikmd /bin/bash

chown abc:abc /var/log/wikmd.log && chown -R abc:abc /wiki && git config --global user.email "wikmd@no-mail.com" && git config --global user.name "wikmd" && chown -R abc:abc /app/wikmd

1. PermissionError: [Errno 13] Permission denied: ‘/var/log/wikmd.log’

“app” tilhører abc:abc:

drwxr-xr-x 1 abc abc 4096 Mar 19 11:24 app

“wikmd.log” tilhører 911:abc:

-rw-r--r-- 1 911 abc 0 Apr 19 08:54 wikmd.log

Fortsatt feil ved endring av eierskap til root:root

Løsning: chown abc:abc /var/log/wikmd.log

2. PermissionError: [Errno 13] Permission denied: ‘/wiki/img’

De kopierte filene i /wiki tilhører 911:abc, mens mappa eies av root:

drwxr-xr-x 2 root root 4096 Apr 19 08:54 wiki

-rw-r--r-- 1 911 abc 2918 Apr 19 08:54 'How to use the wiki.md'

Løsning: chown -R abc:abc /wiki

Setter dette manuelt med verdiene fra wikmd/config.py#L12-L13

GIT_EMAIL_DEFAULT = "wikmd@no-mail.com"
GIT_USER_DEFAULT = "wikmd"

4. PermissionError ved lagring av ny side
