| ## kn trigger list | ||
|
|
||
| List available trigger. | ||
|
|
||
| ### Synopsis | ||
|
|
||
| List available trigger. | ||
|
|
||
| ``` | ||
| kn trigger list [name] [flags] | ||
| ``` | ||
|
|
||
| ### Examples | ||
|
|
||
| ``` | ||
| # List all trigger | ||
| kn trigger list | ||
| # List all trigger in JSON output format | ||
| kn trigger list -o json | ||
| ``` | ||
|
|
||
| ### Options | ||
|
|
||
| ``` | ||
| -A, --all-namespaces If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace. | ||
| --allow-missing-template-keys 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. (default true) | ||
| -h, --help help for list | ||
| -n, --namespace string Specify the namespace to operate in. | ||
| --no-headers When using the default output format, don't print headers (default: print headers). | ||
| -o, --output string Output format. One of: json|yaml|name|go-template|go-template-file|template|templatefile|jsonpath|jsonpath-file. | ||
| --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]. | ||
| ``` | ||
|
|
||
| ### Options inherited from parent commands | ||
|
|
||
| ``` | ||
| --config string kn config file (default is $HOME/.kn/config.yaml) | ||
| --kubeconfig string kubectl config file (default is $HOME/.kube/config) | ||
| --log-http log http traffic | ||
| ``` | ||
