verification-argocd-appset-prgen

Argo CD ApplicationSet の PullRequest Generator 機能の検証用リポジトリ

検証環境の構築

• Argo CD 用の secret を用意

read -s ARGOCD_ADMIN_PASSWORD
kubectl create secret generic argocd-secret -oyaml --dry-run=client \
  --from-literal=admin.password=$ARGOCD_ADMIN_PASSWORD | kubectl neat \
  > argocd/overlays/dev-with-secrets/secret-argocd.yaml

read -s GITHUB_TOKEN
kubectl create secret generic github-token -oyaml --dry-run=client \
  --from-literal=token=$GITHUB_TOKEN  | kubectl neat \
  > argocd/overlays/dev-with-secrets/secret-github-token.yaml

• Argo CD のインストール

kustomize build argocd/overlays/dev-with-secrets | kubectl apply -f-

検証

• Review Apps 環境構築用マニフェスト (ApplicationSet) の適用
  • 対象 app-repo: https://github.com/cloudnativedaysjp/dreamkast
  • 対象 labels: reviewapps/ignore

kubectl apply -f reviewapps/dreamkast-dk.yaml

• Application が生えていることの確認
  • HEALTH STATUS が Progressing のままであることは意図通り (検証環境には Ingress controller が存在しないため)

$ kubectl get app -n argocd
NAME                SYNC STATUS   HEALTH STATUS
dreamkast-dk-1207   Synced        Progressing
dreamkast-dk-1235   Synced        Progressing
dreamkast-dk-1237   Synced        Progressing

• Review Apps 環境に Deployment, Service, Ingress が存在することの確認

$ kubectl get deployment,svc,ing -n dreamkast-dk-1207
