Men-deploy aplikasi contoh Butik Online

Panduan ini menjelaskan cara menginstal aplikasi contoh Butik Online untuk mendemonstrasikan Cloud Service Mesh. Lihat panduan penyediaan jika Anda perlu menyediakan Cloud Service Mesh.

Mendownload dan men-deploy contoh

Untuk men-deploy aplikasi, Anda harus mendownload manifes Online Boutique dari repo anthos-service-mesh-packages menggunakan kpt terlebih dahulu. Aplikasi contoh Butik Online di repo anthos-service-mesh-packages diubah dari kumpulan manifes asli di repo microservices-demo. Dengan mengikuti praktik terbaik, setiap layanan di-deploy di namespace terpisah dengan akun layanan yang unik.

1. Instal kpt jika Anda belum melakukannya:

   gcloud components install kpt
   

2. Download contoh menggunakan kpt:

   kpt pkg get \
     https://github.com/GoogleCloudPlatform/anthos-service-mesh-packages.git/samples/online-boutique \
     online-boutique
   

   Output yang diharapkan

   Package "online-boutique":
   Fetching https://github.com/GoogleCloudPlatform/anthos-service-mesh-packages@main
   From https://github.com/GoogleCloudPlatform/anthos-service-mesh-packages
   * branch            main       -> FETCH_HEAD
   Adding package "samples/online-boutique".
   Fetched 1 package(s).
   

3. Buka direktori online-boutique:

   cd online-boutique
   

4. Buat namespace untuk aplikasi:

   kubectl apply -f kubernetes-manifests/namespaces
   

   Output yang diharapkan:

   namespace/ad created
   namespace/cart created
   namespace/checkout created
   namespace/currency created
   namespace/email created
   namespace/frontend created
   namespace/loadgenerator created
   namespace/payment created
   namespace/product-catalog created
   namespace/recommendation created
   namespace/shipping created
   

5. Deploy sampel ke cluster.

   1. Buat akun layanan dan deployment:

      kubectl apply -f kubernetes-manifests/deployments
      

      Output yang diharapkan:

      serviceaccount/ad created
      deployment.apps/adservice created
      serviceaccount/cart created
      deployment.apps/cartservice created
      serviceaccount/checkout created
      deployment.apps/checkoutservice created
      serviceaccount/currency created
      deployment.apps/currencyservice created
      serviceaccount/email created
      deployment.apps/emailservice created
      serviceaccount/frontend created
      deployment.apps/frontend created
      serviceaccount/loadgenerator created
      deployment.apps/loadgenerator created
      serviceaccount/payment created
      deployment.apps/paymentservice created
      serviceaccount/product-catalog created
      deployment.apps/productcatalogservice created
      serviceaccount/recommendation created
      deployment.apps/recommendationservice created
      serviceaccount/shipping created
      deployment.apps/shippingservice created
      

   2. Buat layanan:

      kubectl apply -f kubernetes-manifests/services
      

      Output yang diharapkan:

      service/adservice created
      service/cartservice created
      service/checkoutservice created
      service/currencyservice created
      service/emailservice created
      service/frontend created
      service/frontend-external created
      service/paymentservice created
      service/productcatalogservice created
      service/recommendationservice created
      service/shippingservice created
      

   3. Buat entri layanan:

      kubectl apply -f istio-manifests/allow-egress-googleapis.yaml
      

      Output yang diharapkan:

      serviceentry.networking.istio.io/allow-egress-googleapis created
      serviceentry.networking.istio.io/allow-egress-google-metadata created
      

Mengaktifkan injeksi otomatis sidecar

1. Terapkan label injeksi default ke namespace aplikasi.

   for ns in ad cart checkout currency email frontend loadgenerator \
      payment product-catalog recommendation shipping; do
         kubectl label namespace $ns istio-injection=enabled --overwrite
   done;
   

   Output yang diharapkan:

   namespace/ad labeled
   namespace/cart labeled
   namespace/checkout labeled
   namespace/currency labeled
   namespace/email labeled
   namespace/frontend labeled
   namespace/loadgenerator labeled
   namespace/payment labeled
   namespace/product-catalog labeled
   namespace/recommendation labeled
   namespace/shipping labeled
   

2. Jika Anda menggunakan Cloud Service Mesh terkelola dan men-deploy bidang data terkelola opsional, anotasikan namespace aplikasi sebagai berikut:

   for ns in ad cart checkout currency email frontend loadgenerator \
      payment product-catalog recommendation shipping; do
         kubectl annotate --overwrite namespace $ns mesh.cloud.google.com/proxy='{"managed":"true"}'
   done;
   

3. Mulai ulang pod:

   for ns in ad cart checkout currency email frontend loadgenerator \
      payment product-catalog recommendation shipping; do
         kubectl rollout restart deployment -n ${ns}
   done;
   

   Output yang diharapkan:

   deployment.apps/adservice restarted
   deployment.apps/cartservice restarted
   deployment.apps/checkoutservice restarted
   deployment.apps/currencyservice restarted
   deployment.apps/emailservice restarted
   deployment.apps/frontend restarted
   deployment.apps/loadgenerator restarted
   deployment.apps/paymentservice restarted
   deployment.apps/productcatalogservice restarted
   deployment.apps/recommendationservice restarted
   deployment.apps/shippingservice restarted
   

Mengekspos dan mengakses aplikasi

Cara mengekspos aplikasi di luar mesh bergantung pada apakah Anda men-deploy gateway ingress. Anda dapat memilih untuk mengekspos aplikasi menggunakan gateway ingress istio atau menggunakan Layanan Kubernetes.

Anda dapat menjelajahi fitur kemampuan observasi Cloud Service Mesh di konsol Google Cloud . Perhatikan bahwa perlu waktu hingga 10 menit agar grafik topologi menampilkan layanan di mesh Anda.

Pembersihan

Sebelum menghapus Online Boutique, sebaiknya Anda mempelajari Cloud Service Mesh dengan contoh: mTLS, yang menggunakan contoh. Setelah selesai menjelajahi, gunakan perintah berikut untuk menghapus contoh Butik Online:

1. Hapus namespace aplikasi:

   kubectl delete -f kubernetes-manifests/namespaces
   

   Output yang diharapkan:

   namespace "ad" deleted
   namespace "cart" deleted
   namespace "checkout" deleted
   namespace "currency" deleted
   namespace "email" deleted
   namespace "frontend" deleted
   namespace "loadgenerator" deleted
   namespace "payment" deleted
   namespace "product-catalog" deleted
   namespace "recommendation" deleted
   namespace "shipping" deleted
   

2. Hapus entri layanan:

   kubectl delete -f istio-manifests/allow-egress-googleapis.yaml
   

   Output yang diharapkan:

   serviceentry.networking.istio.io "allow-egress-googleapis" deleted
   serviceentry.networking.istio.io "allow-egress-google-metadata" deleted
