One of Docker’s core missions is delivering choice and flexibility across different application languages and frameworks, operating systems, and infrastructure. When it comes to modern applications, the choice of infrastructure is not just whether the application is run on-premises, on virtual machines or bare metal, or in the cloud. It can also be a choice of which architecture – x86, Arm, or GPU. Today, we’re happy to share some updates in Docker Hub that make it easier to access multi-architecture images and scanning results through the Tag UX.

On Monday, February 11, Docker released an update to fix a privilege escalation vulnerability (CVE-2019-5736) in runC, the Open Container Initiative (OCI) runtime specification used in Docker Engine and containerd. This vulnerability makes it possible for a malicious actor that has created a specially-crafted container image to gain administrative privileges on the host. Docker engineering worked with runC maintainers on the OCI to issue a patch for this vulnerability. Docker recommends immediately applying the update to avoid any potential security threats. For Docker Engine-Community, this means updating to 18.09.2 or 18.06.3. For Docker Engine- Enterprise, this means updating to 18.09.2, 18.03.1-ee-6,…

We know that everyone learns differently so the conference provides three options for you. Workshops: Starting this year at DockerCon San Francisco, we introduced a track dedicated to workshops where technical experts deliver 2-hour deep dive sessions with hands-on tutorials to deepen your understanding of Docker technology, Kubernetes, Isito and solutions from our ecosystem partners. Included as part of your conference pass, you must pre-register for workshops to save your seat.  …
