Create an application in a Tencent Cloud TKE cluster-Enterprise Distributed Application Service(EDAS)-阿里云帮助中心

This topic describes how to import a Tencent Cloud TKE cluster into EDAS and deploy an application to the cluster.

Prerequisites

Activate EDAS
Ensure that your Tencent Cloud TKE cluster is running and has public network access.

Register the TKE cluster with ACK

In the ACK console, create a registered cluster to register the target cluster with ACK. For more information, see Create an ACK One registered cluster. After the registration is successful, check the status of the cluster in the ACK console. If the cluster status is Running, the cluster is successfully registered.

Import the TKE cluster into EDAS

Step 1: Configure domain name resolution

You can configure Private DNS in Tencent Cloud to resolve the following domain names for public network access. For more information, see Create a Private Domain.

Note
When you import a cluster into EDAS, EDAS-related controllers are installed in the TKE cluster. The installation process requires downloading resources, such as images and Custom Resource Definition (CRD) resources. If the TKE cluster cannot access the EDAS control plane through a private network, you must configure Private DNS in Tencent Cloud to allow the cluster to download these resources over the public network.

After you create the private domain, add the following DNS records.

Internal same-region endpoint	Public endpoint	Remarks
arms-apm-cn-hangzhou.oss-cn-hangzhou-internal	arms-apm-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com	Helm download address for installing ack-pilot.
edas-vpc.cn-hangzhou	edas.cn-hangzhou.aliyuncs.com	EDAS POP domain name.
aliregistry.oss-cn-hangzhou-internal	aliregistry.oss-cn-hangzhou.aliyuncs.com	Image download verification address.
registry-vpc.cn-hangzhou	registry.cn-hangzhou.aliyuncs.com	Image repository address.
edas-hz.oss-cn-hangzhou-internal	edas-hz.oss-cn-hangzhou.aliyuncs.com	Address for downloading cluster CRD information and other data.

You can use the ping command to obtain the IP address of a public endpoint. Then, use Private DNS to create a record that resolves the corresponding internal same-region endpoint to this public IP address.

ping edas.cn-hangzhou.aliyuncs.com

After you add the DNS records, you can view the details on the DNS Records page.

Note
The preceding example shows how to import a cluster into the China (Hangzhou) region. If you import a cluster into a different region, you must replace the region ID in the domain names accordingly. For a list of regions that EDAS supports, see Endpoints. To obtain the IP address for a domain name, ping the corresponding public endpoint.

Step 2: Import the cluster

Important

Before you import the cluster, copy the KubeConfig file to your local machine and configure the required environment variables. This ensures that your local machine can connect to the cluster. For more information, see Obtain the KubeConfig file of a cluster and use kubectl to connect to the cluster.

Run the following command to download the Helm Chart package.

wget https://edas-hz.oss-cn-hangzhou.aliyuncs.com/helm/edas-helm-chart-1.0.0.tgz

Run the following command to import the cluster into EDAS.
```
helm install edas-cluster edas-helm-chart-1.0.0.tgz --set accessKeyId=xxxx,accessKeySecret=xxxxx,clusterId=c87b5954acef****************
```
- accessKeyId and accessKeySecret: The AccessKey ID and AccessKey secret. The associated account must have permissions to import the cluster into EDAS and read the ACK cluster.
- clusterId: The ID of the registered cluster. You can obtain this ID from the ACK console.
The import process takes about two minutes. You can check the import result in one of the following two ways:
- Run the following command to view the logs.
```
kubectl logs job/edas-helm-install-job -n kube-system
```
- In the EDAS console, go to the Resource Management > Container Service K8s Cluster page to view the import status and logs.
After the import is complete, run the following command. The output shows that two new namespaces are added to the cluster.
```
kubectl get namespaces
```

Deploy the application

Download the Helm Chart package for the test application.

wget https://edas-hz.oss-cn-hangzhou.aliyuncs.com/helm/edas-apps-chart-1.0.0.tgz

Run the following command to create the application.
```
helm install edas-apps edas-apps-chart-1.0.0.tgz
```
You can view the created application in the EDAS console.
