Docker Captains are select members of the community that are both
experts in their field and are passionate about sharing their
Docker knowledge with others.“Docker Captains Take 5” is a regular
blog series where we get a closer look at our Captains and ask them
the same broad set of questions ranging from what their best Docker

You might have heard about a new Linux vulnerability that was released last week, CVE-2022-0847, aka “Dirty Pipe”.This vulnerability overwrites
supposedly read-only files in the Linux kernel host, which could
