This project provides Docker images to periodically back up a MySQL database to AWS S3, and to restore from the backup as needed.
The Docker & Docker Compose system requirements are Linux Ubuntu as the OS (other operating systems are supported as well), an absolute minimum 512MB RAM (2GB recommended)
In order to install docker Ubuntu, you will need to meet the following requirements:
- OS: Linux Ubuntu
- Memory: 512MB RAM (2GB Recommended)
- Disk: Sufficient amount to run the Docker containers you wish to use
- CPU: Dependant on the applications you wish to run in the containers
- Images are tagged by the major MySQL version supported:
8.0
,8.1
or8.2
. - The
SCHEDULE
variable determines backup frequency. See go-cron schedules documentation here. Omit to run the backup immediately and then exit. - If
PASSPHRASE
is provided, the backup will be encrypted using GPG. - Run
docker exec <container name> sh backup.sh
to trigger a backup ad-hoc. - If
BACKUP_KEEP_DAYS
is set, backups older than this many days will be deleted from S3. - Set
S3_ENDPOINT
if you're using a non-AWS S3-compatible storage provider.
- Install Docker and Docker-Compose
- Bring up your stack by running
git clone https://github.com/hitechnix/mysql-backup.git \
&& cd mysql-backup \
&& cp .env.example .env
- Edit environment variable
# MySQL
MYSQL_USER=user
MYSQL_DATABASE=database
MYSQL_PASSWORD=password
MYSQL_ROOT_PASSWORD=rootpassword
# Backup
SCHEDULE=@weekly
BACKUP_KEEP_DAYS=7
