Backup and Recovery On Moodle Learning System from Bitnami Docker
Now I am planning to implement my online learning application by using Moodle CMS available as open source. And I am decided to use Bitnami Docker image to host the CMS application. For that , I did the following command in my AWS machine,
$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-moodle/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d
And After I am getting blank initial application. Here My doubt is that, After designing my learning management system by customizing the pages and course, How I can take a backup from the current running image ?
Because , Initially I used docker image from Bitnami. After that I am designing according to my requirements. So here How I can take a backp for this running application after setuping?
I am new to Moodle and CMS. Please anyone guide me to resolve my confusions here ? And suggest any documentation for reading.
