 Namaste !! Dear DevOps enthusiastic, In this article I would like to share the experimenting of data that is persistence which we learned in an earlier blog post .  In real world these data volumes need to be backed up regularly and if in case of any disaster we can restore the data from these backups from such volumes   Docker Volumes Backup and Restore This story can happen in any real-time project, The data from the on-premises data center to migrate to a cloud platform. One more option is when Database servers backup and restore to different Private networks on a cloud platform. Here I've tested this use-case on two Vagrant VirtualBox's. One used for backup and other for restore MySQL container. Setting up the Docker MySQL container with Volume Step 1 : Let's create a volume with a name as first_vol: docker volume create first_vol #create docker volume ls #Confirm Step 2: create a container with volume for backup of My SQL Database image docke...

In this blog-post, I would like to discuss Docker Storage and storage drivers and Application data management using Docker Volumes. Every fact we explore in detailed experimented and collected and published here.

Linux got the Logical storage devices where you can make use of single disk into multiple disks drives called logical drives as we see in Windows (C: D:). Disk space can be shared across multiple containers partition of disks and a group of partitions. Docker uses this capability with special storage dr...
