이 주제는 예시일 뿐입니다. 인증 기관(CA) Let's Encrypt에서 TLS 인증서를 가져오는 방법을 설명합니다.
이러한 단계는 주로 CA에서 승인한 인증서/키 쌍을 가져올 수 있는 다른 방법이 없는 경우에 수행하는 예시입니다. 이 예시에서는 Let's Encrypt CA, Certbot 클라이언트, Google Cloud Platform Cloud DNS를 사용하여 인증서를 생성하는 방법을 보여줍니다.
이러한 사용자 인증 정보를 사용할 수 있는 위치
클러스터 외부에 노출되는 Istio 인그레스 게이트웨이 두 개에 TLS 사용자 인증 정보를 제공해야 합니다.
GKE를 사용하는 경우 고정 외부 IP 주소 예약의 안내를 따라 2개의 고정 IP 주소를 만듭니다. 주소에 원하는 이름을 지정할 수 있습니다(예: apigee-hybrid-mart 및 apigee-hybrid-runtime). 완료되면 다음 단계에서 2개의 IP 번호를 클러스터 구성에 사용할 수 있습니다. 예를 들면 35.225.131.189 및 34.66.75.196입니다.
Anthos GKE를 사용하는 경우 Anthos GKE 문서의 안내를 따라 2개의 고정 IP 주소를 만듭니다.
MART 엔드포인트용 레코드 집합을 만듭니다. 이전 단계에서 가져온 외부 IP를 입력하고 도메인 이름에 프리픽스를 추가합니다(예: mart). 자세한 내용은 새 레코드 만들기를 참조하세요.
apigee-hybrid-runtime용으로 예약한 외부 IP를 가져옵니다.
Istio 인그레스 엔드포인트의 레코드 집합을 만듭니다. 이 주소는 하이브리드 게이트웨이에 대해 API 호출을 수행하기 위해 사용됩니다. 이전 단계에서 가져온 외부 IP를 입력하고 도메인 이름에 프리픽스를 추가합니다(예: apitest). 자세한 내용은 새 레코드 만들기를 참조하세요.
도메인 서버를 관리하도록 Cloud DNS를 설정했으므로 이제 Cloud VM에서 dns_google 플러그인을 사용하여 Certbot 클라이언트를 설치합니다. 클라이언트를 사용 설정하면 Let's Encrypt 엔드포인트에서 도메인에 대해 승인된 인증서를 가져올 수 있습니다.

For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\n\nThis topic is intended as an example only. It explains how to obtain a TLS certificate from\nthe certificate authority (CA) [Let's Encrypt](https://letsencrypt.org).\nThese steps are provided primarily as an example to follow if you do not have\nanother ready way to obtain a certificate/key\npair that is authorized by a CA. The example shows how to generate certificates\nusing the [Let's Encrypt](https://letsencrypt.org) CA, the\n[Certbot client](https://certbot.eff.org/about/), and Google Cloud Platform [Cloud DNS](https://cloud.google.com/dns/docs/).\n\nWhere you can use these credentials\n-----------------------------------\n\n\nYou must provide TLS credentials for two Istio ingress gateways that are exposed\noutside the cluster:\n\nSee also [External connections](/apigee/docs/hybrid/v1.1/ports#external).\n\nRequirements\n------------\n\n- You will need a domain name obtained through a domain name registrar. You can register a domain name through Google Domains or another domain registrar of your choice.\n\nConfigure Cloud DNS\n-------------------\n\nTo obtain authorized TLS credentials, you must have a qualified domain name. The following steps explain how to [Google Cloud DNS](https://cloud.google.com/dns/) to obtain a domain name and manage your domain servers.\n\n1. Open the [Google Cloud console](https://console.cloud.google.com) and log in with the account you created in [Step 1: Create a Google Cloud account](/apigee/docs/hybrid/v1.1/precog-gcpaccount).\n2. Select the project that you created in [Step 2: Create a GCP project](/apigee/docs/hybrid/v1.1/precog-gcpproject).\n3. Enable the DNS API. See [Enabling APIs](https://cloud.google.com/apis/docs/getting-started#enabling_apis).\n4. Create two static IP addresses:\n - If you are on GKE, follow the instructions in [Reserving a static external IP address](https://cloud.google.com/compute/docs/ip-addresses/reserve-static-external-ip-address) to create two static IP addresses. You can give the addresses any name you wish, for example: `apigee-hybrid-mart` and `apigee-hybrid-runtime`. When you finish, you will have two IP numbers to use in the cluster configuration in the next step. For example: `35.225.131.189` and `34.66.75.196`\n - If you are on Anthos GKE, follow instructions in the [Anthos GKE documentation](/anthos/clusters/docs/on-prem/1.5/how-to/install-static-ips#configuring_static_ips) to create two static IP addresses.\n5. Create a managed public zone. For instructions, see [Create a managed public zone](https://cloud.google.com/dns/docs/set-up-dns-records-domain-name#create_a_managed_public_zone).\n6. Get the External IP you reserved for the `apigee-hybrid-mart`.\n7. Create record set for the MART endpoint. Enter the External IP you obtained in the previous step and add a prefix to the domain name, such as `mart`. For instructions, see [Create a new record](https://cloud.google.com/dns/docs/set-up-dns-records-domain-name#create_a_new_record).\n\n8. Get the External IP that you reserved for `apigee-hybrid-runtime`.\n9. Create record set for the Istio ingress endpoint. This is the address for making API calls to the hybrid gateway. Enter the External IP you obtained in the previous step and add a prefix to the domain name, such as `apitest`. For instructions, see [Create a new record](https://cloud.google.com/dns/docs/set-up-dns-records-domain-name#create_a_new_record).\n\n10. Copy the DNS record data, as shown in the following example:\n\n11. Return to your domain page at [Google Domains](https://domains.google.com).\n12. Select your domain.\n13. Select **DNS**.\n14. In the Name Servers section, click **Edit**.\n15. Enter the domain name servers that you copied from the Network Services Cloud DNS\n page:\n\n\nNow, your Google Cloud DNS will manage the DNS records for your domain.\n\nInstall Certbot on a VM\n-----------------------\n\n\nNow that you have Cloud DNS set up to manage your domain servers, you will install the\nCertbot client with the\n[dns_google](https://certbot-dns-google.readthedocs.io/en/stable/) plugin on a Cloud VM. The client enables\nyou to get authorized certificates for your domain from a Let's Encrypt endpoint.\n\n1. Open the [Google Cloud console](https://console.cloud.google.com) and log in with the account you created in [Step 1: Create a Google Cloud account](/apigee/docs/hybrid/v1.1/precog-gcpaccount).\n2. Select the project that you created in [Step 2: Create a GCP project](/apigee/docs/hybrid/v1.1/precog-gcpproject).\n3. Select **IAM \\& admin \\\u003e Service accounts** .\n\n The **Service accounts view** displays a list of the project's service accounts.\n4. To create a new service account, click **+Create Service Account** at the top of the view.\n\n The **Service account details** view displays.\n5. In the **Service account name** field, enter the name of the service account.\n\n You can optionally add a description in the **Service account description**\n field. Descriptions are helpful at reminding you what a particular service account is used\n for.\n6. Click **Create** .\n\n GCP creates a new service account and displays the **Service account\n permissions** view. Use this view to assign a role to your new service account.\n7. Click the **Select a role** drop-down list.\n8. Select the **Project Owner** role.\n9. Click **Continue**.\n10. Click **Done**.\n11. In the GCP console, select **Compute Engine \\\u003e VM Instances**.\n12. Create a VM instance named **certmanager**.\n13. Under the Boot Disk section, choose CentOS7 and 20 GB for the SSD persistent drive.\n14. Set the Service Account to the one you created above.\n15. Install Certbot and the [dns_google](https://certbot-dns-google.readthedocs.io/en/stable/) plugin on the machine and run the Certbot client: \n\n sudo su -\n yum -y install yum-utils\n yum install certbot -y\n yum install certbot-dns-google -y\n certbot certonly --dns-google -d *.\u003cvar translate=\"no\"\u003eyour_domain_name\u003c/var\u003e,*.\u003cvar translate=\"no\"\u003eyour_domain_name\u003c/var\u003e --server https://acme-v02.api.letsencrypt.org/directory\n \n\n For example: \n\n sudo su -\n yum -y install yum-utils\n yum install certbot -y\n yum install certbot-dns-google -y\n certbot certonly --dns-google -d *.apigee-hybrid-docs.net,*.apigee-hybrid-docs.net --server https://acme-v02.api.letsencrypt.org/directory\n\n16. You can now find your authorized certificate and private key files in this directory: `cd /etc/letsencrypt/live/`\u003cvar translate=\"no\"\u003eyour_domain_name\u003c/var\u003e`/`\n\n\n For example:\n\n\n cd /etc/letsencrypt/live/apigee-hybrid-docs.net\n ls\n cert.pem chain.pem fullchain.pem privkey.pem README\n\n \u003cbr /\u003e\n\n17. Copy the files `fullchain.pem` and `privkey.pem` to your local machine.\n18. Update your overrides file to point to the certificate and private key. For the `hostAlias`, use the DNS name that you created previously.\n\n\n For example: \n\n ```\n envs:\n - name: test\n sslCertPath: \"$HOME/hybrid/apigee-hybrid-setup/tls/fullchain.pem\"\n sslKeyPath: \"$HOME/hybrid/apigee-hybrid-setup/tls/privkey.pem\"\n hostAlias: \"apitest.apigee-hybrid-docs.net\"\n mart:\n nodeSelector:\n key: cloud.google.com/gke-nodepool\n value: apigee-runtime\n sslCertPath: \"$HOME/hybrid/apigee-hybrid-setup/tls/fullchain.pem\"\n sslKeyPath: \"$HOME/hybrid/apigee-hybrid-setup/tls/privkey.pem\"\n replicaCountMin: 1\n replicaCountMax: 1\n hostAlias: \"mart.apigee-hybrid-docs.net\"\n ```\n19. Apply the changes:\n If you changed the `mart` configuration, apply the changes:\n\n ```\n apigeectl apply -f your_overrides_file -c mart\n ```\n\n\n If you changed the `envs` configuration, apply the changes: \n\n ```\n apigeectl apply -f your_overrides_file -c runtime\n ```\n\nTest the configuration\n----------------------\n\n20. Deploy and test a proxy, as explained in [Create and deploy a new API proxy](/apigee/docs/hybrid/v1.1/test-new-proxy)."]]
