To remove a value from config file

kubectl tekton config results token="" --prompt=false

Configure specific properties

kubectl tekton config results host token

Configure can also be called with the group name. Only configurations from that group will be prompted or configured.

kubectl tekton config results client

Non-interactive configuration (no validation).

kubectl tekton config results host="https://localhost:8080" token="test-token" --prompt="false"

Non-interactive prompt can also use the automated suggestions if the values are not provided

This is update host and client-type from default or automated values.

The configuration is stored in kubeconfig context extension. This enables storing multiple tekton results configuration per context.

In Openshift platform with proper access the CLI can discover installed tekton results instances.

Fetching Resources

List resources from a namespace

kubectl tekton get pr -n default

List limited resources from a namespace. By default only 10 resources are listed.

kubectl tekton get pr -n default --limit 20

Get resources by specifying name. Partial name can also be provided.

kubectl tekton get pr test -n default

Get resources by specifying UID. Partial UID can also be provided.

kubectl tekton get pr test -n default --uid="e0e4148c-b914"

List resources from a namespace with selectors. All the selectors support partial value.

kubectl tekton get pr -n default 
    --labels="app.kubernetes.io/name=test-app, app.kubernetes.io/component=database"

All selectors can be used together and works as AND operator.

kubectl tekton get pr -n default 
    --labels="app.kubernetes.io/name=test-app"
    --annotations="app.io/timeout=100"

All selectors except OwnerReferences can work with only key or value.

kubectl tekton get pr -n default --annotations="test" --labels="test"

Check if a particular annotation exists, without knowing the value.

kubectl tekton get pr -n default --annotations="results.tekton.dev/log"

OwnerReferences filter can not filter by key/value pair, but the filter should still be provided as key/value.

kubectl tekton get pr -n default --owner-references="kind=Service name=test-service"

Multiple owner references can be provided, but keys of each owner references should be seperated by space.

kubectl tekton get pr -n default 
    --owner-references="kind=Service name=test-service, kind=Deployment name=test-app"

OwnerReferences filter can be used to find child resources.

kubectl tekton get pr -n default --owner-references="name=parent-name"

Filter flag can be used to pass raw filter. Invalid syntax will cause error.

kubectl tekton get pr -n default --filter="data.status.conditions[0].reason in ['Failed']"

All the filters with partial string also.

--labels            filter resources by lables
--annotations       filter resources by annotations
