使用 Omnibus 的 Gitlab Docker Restic 备份脚本

English Deutsch 简体中文

注意：相关文章：

配置备份脚本

首先，使用以下命令生成加密密码

generate_restic_password.sh
pwgen 30 > .restic_password

确保单独备份此密码，否则所有数据都将丢失！

现在在 docker-compose.yml 所在的同一目录中创建 backup.sh：

gitlab_backup.sh
#!/bin/bash
export NAME=$(basename $(pwd))
export RESTIC_REPOSITORY=rest:http://restic:[email protected]:16383/$NAME
export RESTIC_PASSWORD_FILE=.restic_password


if [ ! -f "${RESTIC_PASSWORD_FILE}" ]; then
   echo "Please create .restic_password with the backup encryption password AND BACKUP THAT PASSWORD SEPARATELY!!!"
   exit 1
fi
echo "Initing repo, please ignore any 'already exists' errors"
if [ ! -f ".restic_inited" ]; then
    # Run the restic init command
    restic init

    if [ $? -eq 0 ]; then # if init successful
        # Create the initialization file
        touch ".restic_inited"
        echo "Restic initialized"
    fi
fi

# Save Gitlab-internal PostgreSQL
docker-compose exec -u gitlab-psql gitlab pg_dump -h /var/opt/gitlab/postgresql/ -d gitlabhq_production |  restic --verbose backup --stdin --stdin-filename="$NAME-pgdump.sql"
# Save directories
restic --verbose backup config data index backup.sh docker-compose.yml --exclude=data/gitlab-rails/shared/artifacts/ --exclude=data/postgresql

TL;DR： 在 backup.sh 所在的目录中，运行

create_backup_service.sh
wget -qO- https://techoverflow.net/scripts/create-backup-service.sh | sudo bash /dev/stdin
