How has the recent turmoil within the OpenAI offices changed your plans to use GPT in a business process or product in 2024?
Increased uncertainty means we are more likely to evaluate alternative AI chatbots and LLMs.
No change in plans, though we will keep an eye on the situation.
With Sam Altman back in charge, we are more likely to go all-in with GPT and LLMs.

Docker to Donate its Container Runtime, containerd, to the Cloud Native Computing Foundation

Docker plans to donate its containerd container runtime to the Cloud Native Computing Foundation, a nonprofit organization dedicated to organizing a set of open source container-based cloud-native technologies.

In December, Docker released as open source the code for containerd, which provides a runtime environment for Docker containers. By open sourcing this component of the Docker stack, the company wanted to assure users, partners, and other actors in the container ecosystem that the core container component would remain stable, and that the community would have a say in its advancement.

Designed as an independent component, containerd can be embedded into third-party systems to provide core container capabilities. Now the company has taken the next step in assuring the independence of containerd, by donating it to a third-party organization. Specifically, Docker will propose to the CNCF Technical Oversight Committee (TOC) for containerd to become a CNCF project.

“Having a stable container runtime that the whole industry is collaborating on is good for the entire industry, including Docker,” said Patrick Chanezon, Docker technical staff member. The move also ensures Docker will remain viable component in the growing Kubernetes ecosystem, though it won’t do any favors for alternative container runtimes such as the runtime for Red Hat’s Project Atomic, the CRI-O project, or CoreOS’s rkt.

The company has also been campaigning for containerd inclusion in the broader community for open source cloud-native container technologies: Last month, Docker hosted a containerd summit in San Francisco, which drew representatives from Alibaba, AWS, Google, IBM, Microsoft, Rancher, Red Hat and VMware, among others. It hopes CNCF will announce the acceptance of the project at the CloudNativeCon/KubeCon conference later this month in Berlin.

Starting with the Kubernetes container orchestration engine, CNCF is building a roster of interoperable open source technologies that organizations can use to build out their own cloud-native operations. The containerd runtime would fit snugly into this stack and make a good companion to Kubernetes, Docker argues (Kubernetes 1.5 runs with Docker 1.10.3 to 1.12.3). also,  containerd exposes an API using CNCF’s gRPC and exposes metrics in the Prometheus format, another CNCF project.

Docker had already donated its core container runtime engine, runC, as a reference implementation to the Open Container Initiative, though thought CNCF would be a better fit because it is more centered on supporting code, rather than on specifications, according to Chanezon. “CNCF is more focused on projects and implementation,” Chanezon said.
