A Docker container is built out of a generic, initial image. Over time, you add your own changes to this base image. Processes running inside the container might also save their own data or make other changes. To preserve all of this, commit the current state of your container to a new...
Docker containers are widely used in DevOps and niche web hosting. Today we’ve discussed the various ways how ourDocker Support Engineersmove Docker container to another host in the Docker infrastructure we manage.

Fixed a security bug in Enhanced Container Isolation (ECI) mode where a user could create Docker volumes sourced from restricted directories inside the Docker Desktop VM and mount them into containers, thereby giving the container access to such restricted VM directories.

There are some great options, such as using SQL Server for Linux in another Docker container or targeting a SQL Azure database. I’ll be digging into those solutions in the next couple of articles, but first I want you to see a quick solution where the database server will ind...
Just as physical machine requests were gradually phased out in favor of VMs, it’s more likely than not that Docker will begin to replace the need for VMs in the next few years—if not sooner. In this article I’ll focus on how I leveraged a container approach, using Windows Server ...
