Is it possible to run a Postgres Database as a Docker container and backup it periodically to a NAS?
Yes, it is possible to run a Postgres database as a Docker container and backup it periodically to a NAS. Here are the general steps:
Pull the Postgres Docker image from Docker Hub:
shdocker pull postgres
Create a Docker volume to store the database data:
shdocker volume create postgres_data
Start the Postgres container and mount the volume to the container:
shdocker run --name postgres -v postgres_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=mysecretpassword -d postgres
Use a backup tool like pg_dump to create a backup of the database:
shdocker exec -t postgres pg_dump -U postgres mydatabase > mydatabase_backup.sql
Copy the backup file to the NAS using a file transfer protocol like SCP or SFTP.
Create a script to automate the backup process and run it periodically using a cron job or a task scheduler.
Note that you will need to replace "mysecretpassword" with a strong password of your choice and "mydatabase" with the name of your database. Additionally, you may need to adjust the backup command based on your specific requirements.
