with these script you are able to backup your docker environment. There is one for the compose project, for one mysql or mariadb, one for postgres SQL and one for the docker volumes.
Just download the needed Script/s to /usr/local/sbin and give them the excute (chmod +x SCRIPTNAME) then you could just start it from wherever you are in the filesystem.
This Script backups docker volumes of the system to a defined Path. You could define the volumes and the backup path in the script itself. Also you could configure the days, how long the backup files will remain as backup. After configuration of the script, you could just start it with:
backup-docker-volume.sh
This Script backups mysql or mariaDB containers with mysqldump or mariadb-dump. If you are using more then one database within a container, the script will backup every used database. Just define the backup folder in the script and start it with:
backup-docker-mysql.sh
You can also configure the days, the backupfiles will remain in the backup folder.
Attention: If you are using Docker Secrets, it will not work. More informations here: #1
This Script backups postgres database containers with pg_dumpall. Just define the backup folder in the script and start it with:
backup-docker-postgres.sh
You can also configure the days, the backupfiles will remain in the backup folder.
This Script backups influxdb database containers with influx backup. Just define the backup folder in the script mount it into the container under /backup and start it with:
backup-docker-influxdb.sh
You can also configure the days, the backupfiles will remain in the backup folder.
With the help of backup-docker-compose.sh you are able to backup the whole docker-compose project folder of each docker-compose project you are running. It uses tar.gz to archive all the files and folders to the predifined backup folder. Just configure the script in the top and run it:
backup-docker-compose.sh
You can also configure the days, the backupfiles will remain in the backup folder.
With that script you are able to select the previous stored backup (BACKUPDIR=/backup/mysql pls change that, if needed)
and recover it to the same Container and Database.
- Just store the Script in
/usr/local/sbinand make it executable:sudo chmod +x /usr/local/sbin/recovery-docker-mysql.sh - To start a recovery, execute the script with the following command:
sudo ./recovery-docker-mysql.sh
(root permission is needed as it will grap the MySQL root pw from the Docker Env. If you are using Docker Secrets, it will not work. You need to store the PW in the Script manually: MYSQL_PWD='yourpw')
The script will read trough the backup store and will ask you to select the Container, Database and Backup (Date-Time) you want to recover. When you then approve the task at the end of the script, it will start a recovery within the docker container. (There is no mysql completion message, but you will get a security issue, as a cleartype password is used to connect to mysql)
