container_name: mysql-bkup
command:
- /bin/sh
- -c

volumes:
- ./backup:/backup
environment:
#- FILE_NAME=mariadb_20231217_040238.sql # Optional if file name is set from command
- DB_PORT=3306
- DB_HOST=mariadb
- DB_NAME=mariadb
- DB_USERNAME=mariadb
- DB_PASSWORD=password
```
## Run
```sh
docker-compose up -d
```
## Backup to S3
```sh
docker run --rm --privileged --device /dev/fuse --name mysql-bkup -e "DB_HOST=db_hostname" -e "DB_USERNAME=username" -e "DB_PASSWORD=password" -e "ACCESS_KEY=your_access_key" -e "SECRET_KEY=your_secret_key" -e "BUCKETNAME=your_bucket_name" -e "S3_ENDPOINT=https://s3.us-west-2.amazonaws.com" jkaninda/mysql-bkup bkup -o backup -s s3 -d database_name
```
> To change s3 backup path add this flag : --path /myPath . default path is /mysql_bkup
Simple S3 backup usage
```sh
bkup --operation backup --storage s3 --dbname mydatabase
```
```yaml
version: '3'
services:
mysql-bkup:
image: jkaninda/mysql-bkup
container_name: mysql-bkup
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 "0 1 * * *"` 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:
```conf
* * * * * command to be executed
```
```conf
- - - - -
| | | | |
| | | | ----- Day of week (0 - 7) (Sunday=0 or 7)
| | | ------- Month (1 - 12)
| | --------- Day of month (1 - 31)
| ----------- Hour (0 - 23)
------------- Minute (0 - 59)
```
> At every 30th minute
```conf
*/30 * * * *
```
> “At minute 0.” every hour
```conf
0 * * * *
```
> “At 01:00.” every day
```conf
0 1 * * *
```
## Example of scheduled mode
> Docker run :
```sh
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 bkup --operation backup --dbname $DB_NAME --mode scheduled --period "0 1 * * *"
```
> With Docker compose
```yaml
version: "3"
services:
mysql-bkup:
image: jkaninda/mysql-bkup
container_name: mysql-bkup
privileged: true
devices:
- "/dev/fuse"
command:
- /bin/sh
- -c
- bkup --operation backup --storage s3 --path /mys3_custome_path --dbname database_name --mode scheduled --period "*/30 * * * *"
environment:
- DB_PORT=3306
- DB_HOST=mysqlhost
- DB_USERNAME=userName
- DB_PASSWORD=${DB_PASSWORD}
- ACCESS_KEY=${ACCESS_KEY}
- SECRET_KEY=${SECRET_KEY}
- BUCKETNAME=${BUCKETNAME}
- S3_ENDPOINT=${S3_ENDPOINT}
```
## Kubernetes CronJob
For Kubernetes you don't need to run it in scheduled mode.
Simple Kubernetes CronJob usage:
```yaml
apiVersion: batch/v1
kind: CronJob
metadata:
name: mysql-bkup-job
spec:
schedule: "0 1 * * *"
jobTemplate:
spec:
template:
spec:
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.us-west-2.amazonaws.com"
restartPolicy: Never
```
