For the creation of required files like tasks,pipeline,pipelinRun, triggers and etc you can use the kubectl create -f <file-name> command.

Examples:

kubectl create -f tekton/tasks/list-source.yaml ### Custom task to list source files

kubectl create -f tekton/tasks/update-manifest.yaml ### Custom task to update ArgoCD manifest

kubectl create -f tekton/pipeline/pipeline.yaml ### Pipeline definition

kubectl create -f tekton/pipelineRun/pipelineRun.yaml ### PipelineRun definition
