Helm 으로 k8s 에 앱 배포하기

Helm Command

⚡️ Locally Render Templates with values

• Render chart templates locally and display the output.

• This does not require Tiller. However, any values that would normally be looked up or retrieved in-cluster will be faked locally.

• Additionally, none of the server-side testing of chart validity (e.g. whether an API is supported) is done.

Format

helm template [flags] CHART

Options

-f, --values valueFiles        specify values in a YAML file (can specify multiple) (default [])

Command

$ helm template ./myapp -f ./myapp/values.yaml -f ./myapp/overrides/alpha.yaml

⚡️ Validation & k8s dry-run 해보기

$ helm template ./myapp -f ./myapp/values.yaml -f ./myapp/overrides/alpha.yaml | kubectl apply -f - --dry-run=true --validate=true

⚡️ k8s Cluster 에 앱 띄우기
