trust-manager and Kubernetes version compatibility #227

Open kichel98 opened 7 months ago

kichel98 commented 7 months ago
Hello, I want to use trust-manager but on previous K8s versions like 1.19 and 1.21. I ran through previous releases of trust-manager and your compatibility matrix looks like: trust-manager version kubeVersion
latest (v0.7.0) >= 1.25.0-0
v0.6.0 >= 1.22.0-0
v0.5.0 >= 1.22.0-0
v0.4.0 >= 1.22.0-0
v0.3.0 no kubeVersion in Chart.yaml

My questions are:

  1. Do you remember what was behind introducing requirement kubeVersion >= 1.22.0-0 in v0.4.0?
  2. Was this requirement also valid in previous releases, but simply not included in Chart.yaml? In other words, do you think we can try to use v0.3.0 for kubeVersion=1.19?

@kichel98 The K8s requirements were introduced in https://github.com/cert-manager/trust-manager/commit/57f6cdfc5974865bddd3eb3536a38cdaaed6f225, and I am not sure why 1.22 was chosen as the minimum K8s requirement at the time. Trying out trust-manager 0.3.0 on your legacy clusters is probably worth a try. But you should really consider upgrading to newer Kubernetes. These versions have been EOL for a long time now: https://endoflife.date/kubernetes

Thank you @erikgb, I'll try. Could you send me a link to docs for this version?
