A Gitea backup script for Docker: It creates a .zip backup of Gitea running inside Docker and moves the backup file to the current working directory.

gitea-backup.sh

#!/bin/bash

# This script creates a .zip backup of gitea running inside docker and copies the backup file to the current working directory

echo "Creating gitea backup inside docker containter ..."
docker exec -u git -it -w /tmp $(docker ps -qf "name=gitea_server_1") bash -c '/app/gitea/gitea dump -c /data/gitea/conf/app.ini --file /tmp/gitea-dump.zip'

echo "Copying backup file from the container to the host machine ..."
docker cp $(docker ps -qf "name=gitea_server_1"):/tmp/gitea-dump.zip /tmp

echo "Removing backup file in container ..."
docker exec -u git -it -w /tmp $(docker ps -qf "name=gitea_server_1") bash -c 'rm /tmp/gitea-dump.zip'

echo "Renaming backup file ..."
BACKUPFILE=gitea-dump-$(date +"%Y%m%d%H%M").zip
mv /tmp/gitea-dump.zip $BACKUPFILE

echo "Backup file is available: "$BACKUPFILE

echo "Done."

I managed to restore. My procedure is here:

https://discourse.gitea.io/t/error-500-on-repositories-after-backup-and-restore/6154

For reference, restore info is here https://docs.gitea.io/en-us/backup-and-restore/#using-docker-restore

Since we are using docker, how about backup the top gitea folder of host wich contains docker-compose.yml using tar -cvfp and restore using tar -pzxvf?
With -p parameter we can keep permission of files.

host file tree is:

$ sudo tree -L 4
