vela kube apply

Apply resources in Kubernetes YAML file to clusters.

Synopsis

Apply Kubernetes objects in clusters

Apply Kubernetes objects in multiple clusters. Use --clusters to specify which clusters to apply. If -n/--namespace is used, the original object namespace will be overridden.

You can use -f/--file to specify the object file/folder to apply. Multiple file inputs are allowed. Directory input and web url input is supported as well. File format can be in YAML, JSON or CUE.

vela kube apply [flags]

Examples

  # Apply single object file in managed cluster
  vela kube apply -f my.yaml --cluster cluster-1
  
  # Apply object in CUE, the whole CUE file MUST follow the kubernetes API and contain only one object.
  vela kube apply -f my.cue --cluster cluster-1
  
  # Apply object in JSON, the whole JSON file MUST follow the kubernetes API and contain only one object.
  vela kube apply -f my.json --cluster cluster-1
  
  # Apply multiple object files in multiple managed clusters
  vela kube apply -f my-1.yaml -f my-2.cue --cluster cluster-1 --cluster cluster-2
  
  # Apply object file with web url in control plane
  vela kube apply -f https://raw.githubusercontent.com/kubevela/kubevela/master/docs/examples/app-with-probe/app-with-probe.yaml
  
  # Apply object files in directory to specified namespace in managed clusters
  vela kube apply -f ./resources -n demo --cluster cluster-1 --cluster cluster-2
  
  # Use dry-run to see what will be rendered out in YAML
  vela kube apply -f my.cue --cluster cluster-1 --dry-run

Options

  -c, --cluster strings    The cluster to apply objects. Setting multiple clusters will apply objects in order. (default [local])
      --dry-run            Setting this flag will not apply resources in clusters. It will print out the resource to be applied.
  -f, --file strings       Files that include native Kubernetes objects to apply.
  -h, --help               help for apply
  -n, --namespace string   The namespace to apply objects. If empty, the namespace declared in the YAML will be used.
