Connect services between Consul datacenters with cluster peering

Service meshes provide secure communication across your services within and across your infrastructure, including on-premises and cloud environments. As your organization scales, it may need to deploy services in multiple cloud providers in different regions. Cluster peering enables you to connect multiple Consul clusters, letting services in one cluster securely communicate with services in the other.

Cluster peering removes some of the administrative burdens associated with WAN federation. Because there is no primary cluster, administrative boundaries are clearly separated per cluster since changes in one Consul cluster does not affect peered clusters. For more information on differences between WAN federation and cluster peering, refer to the cluster peering documentation.

In this tutorial you will:

• Deploy two managed Kubernetes environments with Terraform
• Deploy Consul in each Kubernetes cluster
• Deploy the microservices from HashiCups, a demo application, in both Kubernetes cluster
• Peer the two Consul clusters
• Connect the services across the peered service mesh

Scenario overview

HashiCups is a coffee-shop demo application. It has a microservices architecture and uses Consul service mesh to securely connect the services. In this tutorial, you will deploy HashiCups services on Kubernetes clusters in two different regions. By peering the Consul clusters, the frontend services in one region will be able to communicate with the API services in the other.

HashiCups uses the following microservices:

• The nginx service is an NGINX instance that routes requests to the frontend microservice and serves as a reverse proxy to the public-api service.
• The frontend service provides a React-based UI.
• The public-api service is a GraphQL public API that communicates with the products-api and the payments services.
• The products-api service stores the core HashiCups application logic, including authentication, coffee (product) information, and orders.
• The postgres service is a Postgres database instance that stores user, product, and order information.
• The payments service is a gRCP-based Java application service that handles customer payments.

Prerequisites

If you are not familiar with Consul's core functionality, refer to the Consul Getting Started tutorials collection first.

For this tutorial, you will need:

• A Google Cloud account configured for use with Terraform
• gcloud CLI with the gke-cloud-auth-plugin plugin installed

• kubectl v1.21 or later
• git v2.0 or later
• terraform v1.2 or later
• consul-k8s v1.1.1
• jq v1.6 or later

This tutorial uses Terraform automation to deploy the demo environment. You do not need to know Terraform to successfully complete this tutorial.

Clone example repository

Clone the GitHub repository containing the configuration files and resources.

$ git clone https://github.com/hashicorp-education/learn-consul-cluster-peering

Change into the directory with the newly cloned repository.

$ cd learn-consul-cluster-peering

This repository has the following:

• The dc1 directory contains Terraform configuration to deploy an GKE cluster in us-central1-a.
• The dc2 directory contains Terraform configuration to deploy an GKE cluster in us-west1-a.
• The k8s-yamls directory contains YAML configuration files that support this tutorial.
• The hashicups-v1.0.2 directory contains YAML configuration files for deploying HashiCups.

Deploy Kubernetes clusters and Consul

In this section, you will create a Kubernetes cluster on each datacenter, and install Consul to provide service mesh functionality.

Initialize the Terraform configuration for dc1 to download the necessary providers and modules.

$ terraform -chdir=google-cloud/dc1 initInitializing the backend...## ...Initializing provider plugins...## ...Terraform has been successfully initialized!## ...

Use the terraform.tfvars.example template file to create a terraform.tfvars file in the dc1 folder.

$ cp google-cloud/dc1/terraform.tfvars.example google-cloud/dc1/terraform.tfvars

Edit this file to specify your project ID and zones. By default, dc1 deploys to us-central1-a.

project = "xx-000000000000000000000000000"zone = "us-central1-a"

Open a new terminal window and initialize the Terraform configuration for dc2.

$ terraform -chdir=google-cloud/dc2 initInitializing the backend...## ...Initializing provider plugins...## ...Terraform has been successfully initialized!## ...

Next, use the terraform.tfvars.example template file to create a terraform.tfvars file in the dc2 folder.

$ cp google-cloud/dc2/terraform.tfvars.example google-cloud/dc2/terraform.tfvars

Edit this file to specify your project ID and zones. By default, dc2 deploys to us-west1-b.

project = "xx-000000000000000000000000000"zone = "us-west1-a"

Then, deploy the resources for dc1. Confirm the run by entering yes. This will take about 15 minutes to deploy your infrastructure.

$ terraform -chdir=google-cloud/dc1 apply## ...Plan: 33 to add, 0 to change, 0 to destroy.## ...Do you want to perform these actions?  Terraform will perform the actions described above.  Only 'yes' will be accepted to approve.  Enter a value: yes## ...Apply complete! Resources: 25 added, 0 changed, 0 destroyed.Outputs:get-credentials_command = "gcloud container clusters get-credentials --zone us-central1-a dc1"rename-context_cmd = "kubectl config rename-context gke_xx-000000000000000000000000000_us-central1-a_dc1 dc1"

Deploy the resources for dc2. Confirm the run by entering yes.

$ terraform -chdir=google-cloud/dc2 apply## ...Plan: 15 to add, 0 to change, 0 to destroy.## ...Apply complete! Resources: 15 added, 0 changed, 0 destroyed.

Review Consul deployment

Terraform automatically deploys Consul into each datacenter using the Helm charts consul-helm-dc1.yaml and consul-helm-dc2.yaml located in the ./k8s-yamls/ folder. The following configuration shows the mandatory features for cluster peering enabled in dc1. Features enabled in dc2 are equivalent.

global:  datacenter: dc1  ##...  peering:    enabled: true  tls:    enabled: true  ##...meshGateway:  enabled: true  replicas: 1##...

Configure kubectl

Now that you have deployed the two datacenters, configure the kubectl tool to interact with the Kubernetes cluster in the first datacenter. Notice that this command stores the cluster connection information for dc1.

Set the current Google Cloud project, and then fetch the related credentials.

$ eval $(terraform -chdir=google-cloud/dc1 output -raw set-project_command)Updated property [core/project].

$ eval $(terraform -chdir=google-cloud/dc1 output -raw get-credentials_command)Fetching cluster endpoint and auth data.kubeconfig entry generated for dc1.

Then, rename the first cluster context to dc1. This lets you target this specific Kubernetes cluster in later commands.

$ eval $(terraform -chdir=google-cloud/dc1 output -raw rename-context_command)Context "gke_hc-f7aeccc6321b46ccb29e97f1481_us-central1-a_dc1" renamed to "dc1".

Configure the kubectl tool to interact with the Kubernetes cluster in the second datacenter. Notice that this command stores the cluster connection information for dc2.

$ eval $(terraform -chdir=google-cloud/dc2 output -raw get-credentials_command)Fetching cluster endpoint and auth data.kubeconfig entry generated for dc2.

Then, rename the second cluster context to dc2.

$ eval $(terraform -chdir=google-cloud/dc2 output -raw rename-context_command)Context "gke_hc-f7aeccc6321b46ccb29e97f1481_us-west1-a_dc2" renamed to "dc2".

Verify that Consul was successfully deployed by Terraform in dc1 by inspecting the Kubernetes pods in the dc1 consul namespace.

$ kubectl --context=dc1 --namespace=consul get podsNAME                                          READY   STATUS    RESTARTS   AGEapi-gateway-5bd4dc47cf-mgjsl                  1/1     Running   0          110sconsul-connect-injector-7d68465cf9-fmkxc      1/1     Running   0          107sconsul-mesh-gateway-5554894784-w7pm4          1/1     Running   0          107sconsul-server-0                               1/1     Running   0          106sconsul-server-1                               1/1     Running   0          106sconsul-server-2                               1/1     Running   0          106sconsul-webhook-cert-manager-f59d67cb9-xjv7h   1/1     Running   0          107sprometheus-server-8455cbf87d-5bn4x            2/2     Running   0          107s

Then, verify that Consul was successfully deploeyd by Terraform in dc2 by inspecting the Kubernetes pods in the dc2 consul namespace.

$ kubectl --context=dc2 --namespace=consul get podsNAME                                          READY   STATUS    RESTARTS   AGEconsul-connect-injector-5f68c84545-ndc45      1/1     Running   0          110sconsul-mesh-gateway-675696cd94-hwvzz          1/1     Running   0          110sconsul-server-0                               1/1     Running   0          110sconsul-server-1                               1/1     Running   0          110sconsul-server-2                               1/1     Running   0          110sconsul-webhook-cert-manager-f59d67cb9-nkc6t   1/1     Running   0          110sprometheus-server-8455cbf87d-wscdm            2/2     Running   0          110s

Verify HashiCups deployment

The Terraform deployments for both dc1 and dc2 include a subset of the HashiCups microservices. The dc1 Kubernetes cluster hosts the frontend services, while the dc2 Kubernetes cluster hosts the API and database services. Later in this tutorial, you will connect the Consul datacenters to form the complete HashiCups deployment. The following diagram illustrates how HashiCups is deployed across the two clusters.

Verify HashiCups on first cluster

In dc1, you can view the HashiCups frontend, but the demo application will not display any products because products-api is not deployed.

Terraform deploys in dc1 the K8s YAML files present in hashicups-v1.0.2/dc1. Verify that Terraform has successfully deployed these services by listing the Kubernetes services.

$ kubectl --context=dc1 get serviceNAME         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGEfrontend     ClusterIP   172.20.9.134     <none>        3000/TCP   22skubernetes   ClusterIP   172.20.0.1       <none>        443/TCP    26mnginx        ClusterIP   172.20.9.95      <none>        80/TCP     19spayments     ClusterIP   172.20.22.222    <none>        1800/TCP   13spublic-api   ClusterIP   172.20.153.101   <none>        8080/TCP   16s

List the services registered with Consul in dc1. This command runs consul catalog services in one of the Consul server agents.

$ kubectl exec --namespace=consul -it --context=dc1 consul-server-0 -- consul catalog servicesapi-gatewayconsulfrontendfrontend-sidecar-proxymesh-gatewaynginxnginx-sidecar-proxypaymentspayments-sidecar-proxypublic-apipublic-api-sidecar-proxy

Verify HashiCups on second cluster

Terraform deploys the remaining two HashiCups services in dc2 from the K8s YAML files present in hashicups-v1.0.2/dc2. Verify that Terraform has successfully deployed products-api and postgres by listing the Kubernetes services in dc2.

$ kubectl --context=dc2 get serviceNAME           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGEkubernetes     ClusterIP   172.20.0.1       <none>        443/TCP    15mpostgres       ClusterIP   172.20.165.165   <none>        5432/TCP   28sproducts-api   ClusterIP   172.20.222.90    <none>        9090/TCP   33s

List the services registered with Consul in dc2.

$ kubectl exec --namespace=consul -it --context=dc2 consul-server-0 -- consul catalog servicesconsulmesh-gatewaypostgrespostgres-sidecar-proxyproducts-apiproducts-api-sidecar-proxy

Explore the Consul UI (optional)

Retrieve the Consul UI address for dc1 and open it in your browser.

$ echo "https://$(kubectl --context=dc1 --namespace=consul get services consul-ui -o jsonpath='{.status.loadBalancer.ingress[0].ip}')"https://35.238.125.40

Retrieve the Consul UI address for dc2 and open it in your browser.

$ echo "https://$(kubectl --context=dc2 --namespace=consul get services consul-ui -o jsonpath='{.status.loadBalancer.ingress[0].ip}')"https://34.83.93.166

Explore HashiCups in browser

Open the HashiCups application in your browser and notice that it displays no products.

$ export APIGW_URL=http://$(kubectl --context=dc1 --namespace=consul get services api-gateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}') && echo $APIGW_URLhttp://1.2.3.4

At this point, the public-api service in dc1 is configured to connect to its local instance of the products-api service, however there is currently no instance of products-api on dc1. To use the instance of products-api hosted in another datacenter, you will first configure Consul cluster peering, and then point the upstream to the products-api service in dc2.

Configure Consul cluster peering

You will now peer the two data centers to enable services in dc1 to communicate to products-api in dc2. Consul cluster peering works by defining two cluster roles:

1. A peering acceptor is the cluster that generates a peering token and accepts an incoming peering connection.
2. A peering dialer is the cluster that uses a peering token to make an outbound peering connection with the cluster that generated the token.

Configure cluster peering traffic routing

You can peer Consul clusters by either directly connecting Consul server nodes or connecting the Consul mesh gateways.

Most Kubernetes deployments will not let services connect outside the cluster. This prevents the Consul server pods from communicating to other Kubernetes clusters. Therefore, we recommend configuring the clusters to use mesh gateways for peering. The following file configures the Consul clusters to use mesh gateways for cluster peering:

apiVersion: consul.hashicorp.com/v1alpha1kind: Meshmetadata:  name: meshspec:  peering:    peerThroughMeshGateways: true

Configure cluster peering traffic for both dc1 and dc2 to be routed via the mesh gateways.

$ for dc in {dc1,dc2}; do kubectl --context=$dc apply -f k8s-yamls/peer-through-meshgateways.yaml; donemesh.consul.hashicorp.com/mesh createdmesh.consul.hashicorp.com/mesh created

There are two modes for routing traffic from local services to remote services when cluster peering connections are routed through mesh gateways. In remote mode, your local services contact the remote mesh gateway in order to reach remote services. In local mode, your local services contact their local gateway in order to reach remote services. Refer to the modes documentation and well as the Mesh architecture diagram for more information.

We recommend you use local mode because most Kubernetes deployments do not allow local services to connect outside the cluster. The following configuration specifies local mode for traffic routed over the mesh gateways:

apiVersion: consul.hashicorp.com/v1alpha1kind: ProxyDefaultsmetadata:  name: globalspec:  meshGateway:    mode: local

Configure local mode for traffic routed over the mesh gateways for both dc1 and dc2.

$ for dc in {dc1,dc2}; do kubectl --context=$dc apply -f k8s-yamls/originate-via-meshgateways.yaml; doneproxydefaults.consul.hashicorp.com/global createdproxydefaults.consul.hashicorp.com/global created

Create a peering token

Configuring the peering acceptor role for a cluster generates a peering token and waits to accept an incoming peering connection. The following configuration sets dc1 as the peering acceptor:

apiVersion: consul.hashicorp.com/v1alpha1kind: PeeringAcceptormetadata:  name: dc2spec:  peer:    secret:      name: "peering-token-dc2"      key: "data"      backend: "kubernetes"

Configure a PeeringAcceptor role for dc1.

$ kubectl --context=dc1 apply -f k8s-yamls/acceptor-on-dc1-for-dc2.yamlpeeringacceptor.consul.hashicorp.com/dc2 created

Confirm you successfully created the peering acceptor custom resource definition (CRD).

$ kubectl --context=dc1 get peeringacceptorsNAME         SYNCED   LAST SYNCED   AGEdc2   True     5s            5s

Confirm that the PeeringAcceptor CRD generated a peering token secret.

$ kubectl --context=dc1 get secrets peering-token-dc2NAME                       TYPE     DATA   AGEpeering-token-dc2   Opaque   1      97s

Import the peering token generated in dc1 into dc2.

$ kubectl --context=dc1 get secret peering-token-dc2 -o yaml | kubectl --context=dc2 apply -f -secret/peering-token-dc2 created

Establish a connection between clusters

Configuring a peering dialer role for a cluster makes an outbound peering connection towards a peering acceptor cluster using the specified peering token. The following configuration sets dc2 as the peering dialer and peering-token-dc2 as its token.

apiVersion: consul.hashicorp.com/v1alpha1kind: PeeringDialermetadata:  name: dc1spec:  peer:    secret:      name: "peering-token-dc2"      key: "data"      backend: "kubernetes"

Configure a PeeringDialer role for dc2. This will create a peering connection from the second datacenter towards the first one.

$ kubectl --context=dc2 apply -f k8s-yamls/dialer-dc2.yamlpeeringdialer.consul.hashicorp.com/dc1 created

Verify that the two Consul clusters are peered. This command queries the peering API endpoint on the Consul server agent in dc1.

$ kubectl exec --namespace=consul -it --context=dc1 consul-server-0 \-- curl --cacert /consul/tls/ca/tls.crt --header "X-Consul-Token: $(kubectl --context=dc1 --namespace=consul get secrets consul-bootstrap-acl-token -o go-template='{{.data.token|base64decode}}')" "https://127.0.0.1:8501/v1/peering/dc2" \ | jq

Notice the state is Active, which means that the two clusters are peered successfully.

Export the products-api service

After you peer the Consul clusters, you need to create a configuration entry that defines the services you want to export to other clusters. Consul uses this configuration entry to advertise those services' information and connect those services across Consul clusters. The following configuration exports the products-api service into the dc1 peer.

apiVersion: consul.hashicorp.com/v1alpha1kind: ExportedServicesmetadata:  name: default ## The name of the partition containing the servicespec:  services:    - name: products-api ## The name of the service you want to export      consumers:      - peer: dc1 ## The name of the peering connection that receives the service

In dc2, apply the ExportedServices custom resource file that exports the products-api service to dc1.

$ kubectl --context=dc2 apply -f k8s-yamls/exportedsvc-products-api.yamlexportedservices.consul.hashicorp.com/default created

Confirm that the Consul cluster in dc1 can access the products-api in dc2. This command queries the services API endpoint on the Consul server agent in dc1 about the products-api service from dc2 for its sidecar service ID and the related peer name.

$ kubectl \--context=dc1 --namespace=consul exec -it consul-server-0 \-- curl --cacert /consul/tls/ca/tls.crt \--header "X-Consul-Token: $(kubectl --context=dc1 --namespace=consul get secrets consul-bootstrap-acl-token -o go-template='{{.data.token|base64decode}}')" "https://127.0.0.1:8501/v1/health/connect/products-api?peer=dc2" \| jq '.[].Service.ID,.[].Service.PeerName'

Notice the output contains the products-api sidecar service ID and the name of the related cluster peering.

"products-api-sidecar-proxy-instance-0""dc2"

Create a cross-cluster service intention

In order for communication from products-api service in dc1 to reach public-api in dc2, you must define a ServiceIntentions custom resource definition that enables communication from products-api service in dc1.

apiVersion: consul.hashicorp.com/v1alpha1kind: ServiceIntentionsmetadata:  name: dc1-public-api-to-dc2-products-apispec:  destination:    name: products-api  sources:   - name: public-api     action: allow     peer: dc1

Create a service intention in dc2 that that allows communication from the public-api service in dc1 to the products-api service in dc2.

$ kubectl --context=dc2 apply -f k8s-yamls/intention-dc1-public-api-to-dc2-products-api.yamlserviceintentions.consul.hashicorp.com/dc1-public-api-to-dc2-products-api created

Modify upstream for the public-api service

Next, modify the public-api service definition in dc1 with the updated configuration pointing to upstream in dc2. In this scenario, the correct destination is products-api.virtual.dc2.consul.

Consul uses the DNS syntax for service virtual IP lookups to contact services across peered datacenters. The upstream address is formatted as <service>.virtual[.<namespace>].<peer>.<domain>. The namespace segment is only available in Consul Enterprise.

##...apiVersion: apps/v1kind: Deploymentmetadata:  name: public-apispec:##...  template:  ##...    spec:      serviceAccountName: public-api      containers:        - name: public-api          image: hashicorpdemoapp/public-api:v0.0.6          imagePullPolicy: Always          ports:            - containerPort: 8080          env:            - name: BIND_ADDRESS              value: ":8080"            - name: PRODUCT_API_URI              value: "http://products-api.virtual.dc2.consul"            - name: PAYMENT_API_URI              value: "http://payments:1800"##...

Apply the updated public-api service definition in dc1 with the upstream targeted at dc2.

$ kubectl --context=dc1 apply -f k8s-yamls/public-api-peer.yamlservice/public-api unchangedserviceaccount/public-api unchangedservicedefaults.consul.hashicorp.com/public-api unchangeddeployment.apps/public-api configured

Verify peered Consul services

Verify the cluster peering is operational by opening the HashiCups application in your browser. Notice that it now displays a curated selection of coffee drinks.

$ export APIGW_URL=http://$(kubectl --context=dc1 --namespace=consul get services api-gateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}') && echo $APIGW_URLhttp://1.2.3.4/

Destroy environment

Now that you have peered two Consul clusters, you will now remove the exported service and cluster peering, before destroying the environment.

Remove exported service (optional)

Stop the products-api service from being exported.

$ kubectl --context=dc2 delete -f k8s-yamls/exportedsvc-products-api.yamlexportedservices.consul.hashicorp.com "default" deleted

Remove cluster peering (optional)

To remove a peering connection, delete both the PeeringAcceptor and PeeringDialer resources.

First, delete the PeeringDialer from dc2.

$ kubectl --context=dc2 delete -f k8s-yamls/dialer-dc2.yamlpeeringdialer.consul.hashicorp.com "dc1" deleted

Then, delete the PeeringAcceptor from dc1.

$ kubectl --context=dc1 delete -f k8s-yamls/acceptor-on-dc1-for-dc2.yamlpeeringacceptor.consul.hashicorp.com "dc2" deleted

Verify the two clusters are no longer peered by querying the /health HTTP endpoint in dc1.

$ kubectl exec --namespace=consul -it --context=dc1 consul-server-0 -- curl --insecure 'https://127.0.0.1:8501/v1/health/connect/backend?peer=dc2'[]

Delete supporting infrastructure

Destroy the supporting infrastructure in your first datacenter.

$ terraform -chdir=google-cloud/dc1 destroy##...Plan: 0 to add, 0 to change, 33 to destroy.##...Do you really want to destroy all resources?  Terraform will destroy all your managed infrastructure, as shown above.  There is no undo. Only 'yes' will be accepted to confirm.  Enter a value: yes##...Destroy complete! Resources: 33 destroyed.

Next, destroy the supporting infrastructure in your second datacenter.

$ terraform -chdir=google-cloud/dc2 destroy##...Plan: 0 to add, 0 to change, 15 to destroy.##...Do you really want to destroy all resources?

In this tutorial, you used the Consul cluster peering to route traffic across service meshes in two Consul clusters. In the process, you learned the benefits of using cluster peering for cluster interconnections with minimal shared administrative overhead.

For a much easier experience in configuring cluster peering, consider using Consul on the HashiCorp Cloud Platform (HCP). In HCP, you can easily launch and operate a fully-managed Consul platform in the cloud.

Feel free to explore these tutorials and collections to learn more about Consul service mesh, microservices, and Kubernetes security.
