To change s3 backup path add this flag : --path myPath . default path is /mysql_bkup

Simple S3 backup usage

bkup --operation backup --storage s3 --dbname mydatabase

version: '3'
services:
  mysql-bkup:
    image: jkaninda/mysql-bkup
    container_name: mysql-bkup
    tty: true
    privileged: true
    devices:
    - "/dev/fuse"
    command:
      - /bin/sh
      - -c
      - mysql_bkup --operation restore --storage s3 -f database_20231217_115621.sql.gz
    environment:
      - DB_PORT=3306
      - DB_HOST=mysql
      - DB_NAME=mariadb
      - DB_USERNAME=mariadb
      - DB_PASSWORD=password
      - ACCESS_KEY=${ACCESS_KEY}
      - SECRET_KEY=${SECRET_KEY}
      - BUCKETNAME=${BUCKETNAME}
      - S3_ENDPOINT=${S3_ENDPOINT}

Run in Scheduled mode

This tool can be run as CronJob in Kubernetes for a regular backup which makes deployment on Kubernetes easy as Kubernetes has CronJob resources. For Docker, you need to run it in scheduled mode by adding --mode scheduled flag and specify the periodical backup time by adding `--period "*/30 * * * *" flag.

Make an automated backup on Docker

Syntax of crontab (field description)

The syntax is:

1: Minute (0-59)
2: Hours (0-23)
3: Day (0-31)
4: Month (0-12 [12 == December])
5: Day of the week(0-7 [7 or 0 == sunday])

Easy to remember format:

- - - - command to be executed

| | | | | | | | | ----- Day of week (0 - 7) (Sunday=0 or 7) | | | ------- Month (1 - 12) | | --------- Day of month (1 - 31) | ----------- Hour (0 - 23) ------------- Minute (0 - 59)

Example of scheduling mode

Docker run :

docker run --rm --name mysql-bkup -v $BACKUP_DIR:/backup/ -e "DB_HOST=$DB_HOST" -e "DB_USERNAME=$DB_USERNAME" -e "DB_PASSWORD=$DB_PASSWORD" jkaninda/mysql-bkup:latest  bkup --operation backup --dbname $DB_NAME --mode scheduled --period "*/30 * * * *"

With Docker compose

version: '3'
services:
  mysql-bkup:
    image: jkaninda/mysql-bkup
    container_name: mysql-bkup
    command:
      - /bin/sh
      - -c
      - bkup --operation backup --dbname database_name --mode scheduled --period "*/30 * * * *"
    volumes:
      - ./backup:/backup
    environment:
      - DB_PORT=3306
      - DB_HOST=mariadb
      - DB_USERNAME=mariadb
      - DB_PASSWORD=password

Manual

backup_script.sh

#!/bin/sh
DB_USERNAME='db_username'
DB_PASSWORD='password'
DB_HOST='db_hostname'
DB_NAME='db_name'
BACKUP_DIR='/some/path/backup/'

docker run --rm --name mysql-bkup -v $BACKUP_DIR:/backup/ -e "DB_HOST=$DB_HOST" -e "DB_USERNAME=$DB_USERNAME" -e "DB_PASSWORD=$DB_PASSWORD" jkaninda/mysql-bkup:latest  bkup -o backup -d $DB_NAME

chmod +x backup_script.sh

Your crontab looks like this:

0 1 * * * /path/to/backup_script.sh

Kubernetes CronJob

For Kubernetes you don't need to run it in scheduled mode.

Simple Kubernetes CronJob usage:

apiVersion: batch/v1
kind: CronJob
metadata:
  name: mysql-bkup-job
spec:
  schedule: "0 1 * * *"
  jobTemplate:
    spec:
      template:
        spec:
          backoffLimit: 2
          containers:
          - name: mysql-bkup
            image: jkaninda/mysql-bkup
            securityContext:
              privileged: true
            command:
            - /bin/sh
            - -c
            - bkup -o backup -s s3 --path /custom_path
            env:
              - name: DB_PORT
                value: "3306" 
              - name: DB_HOST
                value: ""
              - name: DB_NAME
                value: ""
              - name: DB_USERNAME
                value: ""
              # Please use secret!
              - name: DB_PASSWORD
                value: "password"
              - name: ACCESS_KEY
                value: ""
              - name: SECRET_KEY
                value: ""
              - name: BUCKETNAME
                value: ""
              - name: S3_ENDPOINT
                value: "https://s3.amazonaws.com"
          restartPolicy: Never
