What this PR does / why we need it:
/kind bug
When I execute the
make dev-env
command to deploy, an error is reported at line 100 of the dev-env script, prompting that the version of kubernetes 1.18 is incompatible. Through checking the relevant code of the helm github repo, we know that when thehelm template
command is executed, the mock data will be used for verification. The mock needs to specify the version of the kubernetes for compatibility. Under the version 3.5 of Helm, kubernetes 1.18 will be used for verification.reference:
https://github.com/helm/helm/blob/release-3.4/pkg/chartutil/capabilities.go#L34
https://github.com/helm/helm/blob/release-3.5/pkg/chartutil/capabilities.go#L32
The deployed chart must be greater than or equal to 1.19.
reference:
https://github.com/karmada-io/multi-cluster-ingress-nginx/blob/main/charts/ingress-nginx/Chart.yaml#L19
so i need to find a version of Helm that is compatible with 1.19. The minimum version is helm3.5
