GETTING STARTED

This section contains the most basic commands for getting a workload running on your cluster.

create

Create a cluster using the data in cluster.json.

snctl create -f ./cluster.json

Create a cluster based on the JSON passed to stdin.

cat cluster.json | snctl create -f -

Edit the data in cluster.yaml in JSON and then create the resource using the edited data.

snctl create -f cluster.yaml --edit -o json

Create a resource from a file or from stdin.

JSON and YAML formats are accepted.

Usage

$ create -f FILENAME

Flags

Name Shorthand Default Usage
allow-missing-template-keys true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.
dry-run false If true, only print the object that would be sent, without sending it.
edit false Edit the API resource before creating.
filename f [] Filename, directory, or URL to files to use to create the resource
kustomize k Process the kustomization directory. This flag can't be used together with -f or -R.
output o Output format. One of: json|yaml|name|go-template|go-template-file|template|templatefile|jsonpath|jsonpath-file.
raw Raw URI to POST to the server. Use the transport specified by the config file.
record false If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
recursive R false Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
save-config false If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged.
selector l Selector (label query) to filter on, supporting '=', '==', and '!='.(e.g. -l key1=value1,key2=value2).
template 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 true If true, use a schema to validate the input before sending it
