tkn task start

Start Tasks

Usage

tkn task start [RESOURCES...] [PARAMS...] [SERVICEACCOUNT]

Synopsis

Start Tasks

Examples

Start Task foo by creating a TaskRun named "foo-run-xyz123" from namespace 'bar':

tkn task start foo -s ServiceAccountName -n bar

The Task can either be specified by reference in a cluster using the positional argument or in a file using the --filename argument.

For params values, if you want to provide multiple values, provide them comma separated like cat,foo,bar

For passing the workspaces via flags:

  • In case of emptyDir, you can pass it like -w name=my-empty-dir,emptyDir=

  • In case of configMap, you can pass it like -w name=my-config,config=rpg,item=ultimav=1

  • In case of secrets, you can pass it like -w name=my-secret,secret=secret-name

  • In case of pvc, you can pass it like -w name=my-pvc,claimName=pvc1

  • In case of volumeClaimTemplate, you can pass it like -w name=my-volume-claim-template,volumeClaimTemplateFile=workspace-template.yaml but before you need to create a workspace-template.yaml file. Sample contents of the file are as follows: spec: accessModes:

    • ReadWriteOnce resources: requests: storage: 1Gi

  • In case of binding a CSI workspace, you can pass it like -w name=my-csi,csiFile=csi.yaml but you need to create a csi.yaml file before hand. Sample contents of the file are as follows:

    driver: secrets-store.csi.k8s.io readOnly: true volumeAttributes: secretProviderClass: "vault-database"
