Github actions

When pushing a tag ti github, github actions automatically creates release for it, with signing of release assets using github workflow identity (see this and this for more info)

So then binary files can be validated using cosign (with checksums.txt and checksubs.txt.sig upload from github release assets):

COSIGN_EXPERIMENTAL=1 cosign verify-blob -signature ~/Downloads/checksums.txt.sig ~/Downloads/checksums.txt

Fork instructions:

1. Set following secrets in your repo:

• DOCKER_USERNAME
• DOCKER_PASSWORD
• COSIGN_KEY
• COSIGN_PASSWORD
• CODECOV_TOKEN

In order to generate cosign token:

# in case cosign not installed
go install github.com/sigstore/cosign/cmd/cosign@v1.4.0

cosign generate-key-pair

, then copy generated key and password to github secrets

2. In .github/workflows/github-actions-demo.yml replace skifdh/test with your own docker image path.

3. Codecov step is standalone, impact only build step, and can be easily commented

for Minikube:

kubectl create configmap config-artifact-pvc \
                         --from-literal=size=10Gi \
                         --from-literal=storageClassName=standard \
                         -o yaml -n tekton-pipelines \
                         --dry-run=client | kubectl replace -f -

Install triggers:
