This repo shows how Tekton can be used to acheive SLSA L2 requirements.

• Clone the repo.
• Edit env.sh to add appropriate values for running the demo.
• Run setup.sh which sets up the environment.
• Run run_pipeline.sh.
• After the pipeline run is done run provenance_extractor.sh

setup.sh based on the settings specified in env.sh, sets up

• Creates a Kubernetes cluster on Google Cloud.
• Sets up Artifact registry on Google Cloud.
• Sets up the KMS on Google Cloud.
• Sets up the necessary Service Accounts.
• Installs Tekton Pipelines and Tekton Chains on the Kubernetes cluster.

run_pipeline.sh first replaces the ENV variables in pipeline_run.yaml with their values defined in env.sh and then runs pipeline_run.yaml.

provenance_extractor.sh extracts the provenance and stores it in the file provenance.
