I made a tiny macOS app to help me organise and monitor all the Kubernetes clusters I run #FluxCD tests on. I have lots of these on my laptop, homelab and clouds, so my kubeconfig is always a mess.

What tells Flagger a release is safe to keep going? What is the safety mechanism?

Hey all -- this is not happening -- Slack will be comped for CNCF communities in perpetuity.
Heads up: on 20 June, Salesforce will no longer be supporting the Kubernetes project with a free enterprise license. We will lose access to channel history older than 90 days, and will likely be forced to migrate to a new platform sometime later this year.
