Running into issues

Hint: you can generate a random secretToken with:

head -c 8 /dev/urandom | base64

Demo setup

• Deploy webhook

make deploy
...
deploy secret and sa (from the config repo)

• Setup ArgoCD
• Setup Tekton (including dashboard and BuildKit daemon)

kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/buildkit/0-buildkitd.yaml

• Create ns demo
• Setup Tekton and its dashboard (notice the versions)

k apply -f https://storage.googleapis.com/tekton-releases/previous/v0.6.0/release.yaml
k apply -f https://github.com/tektoncd/dashboard/releases/download/v0.1.1/release.yaml

Note: In ASK, if rbac is enabled, add clusterrolebinding to the default user (yaml in the config repo)

• Optional: patch argoCD and tkn dashboards

kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'
kubectl patch svc tekton-dashboard -n tekton-pipelines -p '{"spec": {"type": "LoadBalancer"}}'

URLs

• ArgoCD
• Tekton
• Webhook

Notes:

ArgoCD's (resync) interval is hardcoded as 3 minutes (defaultAppResyncPeriod = 180) in https://github.com/argoproj/argo-cd/blob/master/cmd/argocd-application-controller/main.go. This behavior can be overwritten via argocd webhook (i.e., push vs pull)
