The State of the Container curates the top news in the Container ecosystem each month. Sign up for our weekly newsletter to receive these posts via email.
It’s an interesting time for container technology. While Docker is currently on a quest to become the de-facto standard for containers, CoreOS is making inroads and battling head to head for marketshare. Last month, CoreOS announced AppC – a community developed spec that aims to be composable, secure, decentralized and open industry standard. AppC has gained support from the likes of Google, Apcera, Red Hat and VMware. These formats give power to the customer and there are more pilots / use cases taking place at enterprises than ever before. Ultimately, it will be up to IT to decide which format works best for them. In other news, Docker recently put its security guidelines in writing, Mesosphere’s DCOS is now available on Azure and AWS, and Twistlock emerged out of stealth with $2.5M in funding to tackle container security. Be sure to check out John Willis’ article on applying DevOps principles, Peter Yared’s post on Containers-as-a-Service and Adrian Cockcroft’s slides on the Challenges of Monitoring Microservices and Containers.
