What is kOps?

kOps deletes gossip DNS and the protokube binary, and spends the room on Akamai.

kOps publishes alpha and beta tags to this feed rather than finals, and 1.37.0-beta.1 is the largest cut in its visible history. Gossip DNS is gone, along with the protokube binary that served it, Classic Load Balancer support for the API, and Kubernetes 1.31. In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.

What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

kOps vs CircleCI: editorial side-by-side

3.8

kOps deletes gossip DNS and the protokube binary, and spends the room on Akamai.

◆ Current state

kOps publishes alpha and beta tags to this feed rather than finals, and 1.37.0-beta.1 is the largest cut in its visible history. Gossip DNS is gone, along with the protokube binary that served it, Classic Load Balancer support for the API, and Kubernetes 1.31. In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.

◆ Where it's heading

The deliberate narrowing this feed has shown since 1.36 has stopped being incremental. Removing gossip means every cluster now needs real DNS, which ends the configuration that let kOps stand up clusters without a hosted zone. The room that deletion frees is going two visible places: a genuinely new cloud provider in Akamai, and a smaller binary, via grpcnotrace, a forked text/template that lets the linker prune, and a minimal TOML writer replacing go-toml.

◆ Prediction

Akamai moved from SSH keys to subnets, instances and etcd volumes inside a single tag, so it is the provider most likely to keep gaining tasks next. With a gossip migration guide already written, the remaining 1.37 work is the removal reaching users rather than more subtraction.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
