kubectl convert

kubectl convert

Convert config files between different API versions

Synopsis

Convert config files between different API versions. Both YAML and JSON formats are accepted.

The command takes filename, directory, or URL as input, and convert it into format of version specified by –output-version flag. If target version is not specified or not supported, convert to latest version.

The default output will be printed to stdout in YAML format. One can use -o option to change to output destination.

kubectl convert -f FILENAME

Examples

  # Convert 'pod.yaml' to latest version and print to stdout.
  kubectl convert -f pod.yaml
  
  # Convert the live state of the resource specified by 'pod.yaml' to the latest version
  # and print to stdout in json format.
  kubectl convert -f pod.yaml --local -o json
  
  # Convert all files under current directory to latest version and create them all.
  kubectl convert -f . | kubectl create -f -

Options

  -f, --filename stringSlice      Filename, directory, or URL to files to need to get converted.
      --local                     If true, convert will NOT try to contact api-server but run locally. (default true)
      --no-headers                When using the default or custom-column output format, don't print headers.
  -o, --output string             Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
      --output-version string     Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
  -R, --recursive                 Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
      --schema-cache-dir string   If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' (default "~/.kube/schema")
  -a, --show-all                  When printing, show all resources (default hide terminated pods.)
      --show-labels               When printing, show all labels as the last column (default hide labels column)
      --sort-by string            If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
      --template string           Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview].
      --validate                  If true, use a schema to validate the input before sending it (default true)

      --insecure-skip-tls-verify         If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

      --log-dir string                   If non-empty, write log files in this directory
      --logtostderr                      log to standard error instead of files
