Legacy Support
Now lots of apps are still running on Kubernetes clusters version v1.14 or v1.15, while KubeVela core requires the minimum Kubernetes version to be v1.16+.
Currently, the main blocker is KubeVela uses CRD v1, while those old Kubernetes versions don't support CRD v1. So we generate v1beta1 CRD here for convenience. But we have no guarantee that KubeVela core will support the legacy Kubernetes versions.
Follow the instructions in README to create a namespace like vela-system and add the OAM Kubernetes
Runtime helm repo.
$ kubectl create namespace vela-system
$ helm repo add kubevela https://charts.kubevela.net/core
Run the following command to install a KubeVela core legacy chart.
$ helm install -n vela-system vela-core-legacy kubevela/vela-core-legacy
If you'd like to install an older version of the legacy chart, use helm search to choose a proper chart version. Remember
to add flag --devel if you prefer pre-release versions.
$ helm search repo vela-core-legacy -l
