Deploy, release, and monitor applications in the ACK console - User Guide for Kubernetes Clusters| Alibaba Cloud Documentation Center

The Container Service for Kubernetes (ACK) console provides extensive features to help you manage and maintain clusters and applications. This topic describes how to deploy an NGINX application, configure an Ingress, and query log data in the ACK console.

Prerequisites

An ACK cluster is created. For more information, see Create a managed Kubernetes cluster.
Log Service is enabled and Logtail is installed. For more information, see Collect log files from containers by using Log Service.

Step 1: Deploy an NGINX application

Log on to the ACK console.
In the left-side navigation pane of the ACK console, click Clusters.
On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
In the left-side navigation pane of the details page, choose Workloads > Deployments.
On the Deployments page, click Create from YAML in the upper-right corner.
Configure the parameters and click Create.
- In the upper-part of the page, set Namespace to default.
- Set Sample Template to Resource - basic Deployment.
- Configure log collection. For more information about how to configure log collection parameters, see Collect log files from containers by using Log Service.
  Add the following content to the spec field in the template.
  
  Note aliyun_logs_log-nginxvarlog specifies that the name of the created Logstore is log-nginxvarlog. The value stdout specifies that the Logstore collects standard outputs of containers from the specified path.
```
env:
- name: aliyun_logs_log-nginxvarlog
  value: stdout
```
- Change the version of the image that is used to deploy the NGINX application to 1.9.1.
After the NGINX application is created, you can view the application on the Deployments page.

Step 2: Release the NGINX application

In the left-side navigation pane of the details page, choose Network > Services.
On the Services page, click Create in the upper-right corner of the page.

In the Create Service dialog box, set the parameters and click Create.


Parameter	Description
Name	Enter a name for the Service.
Type	Set Type to Cluster IP.
Backend	Select nginx-deployment-basic from the drop-down list.
Port Mapping	Enter a name for the port. Set Service Port to 80, Container Port to 80, and Protocol to TCP.
Annotations	Add one or more annotations to the Service and configure Server Load Balancer (SLB) parameters. For example, the annotation `service.beta.kubernetes.io/alicloud-loadbalancer-bandwidth:20` specifies that the maximum bandwidth of the Service is 20 Mbit/s. This limits the amount of traffic that flows through the Service. For more information, see Use annotations to configure load balancing.
Label	Add one or more labels to the Service. Labels are used to identify the Service.

Step 3: Create an Ingress

In the left-side navigation pane of the details page, choose Network > Ingresses.
On the Ingresses page, click Create in the upper-right corner of the page.
In the Create dialog box, set the required parameters and click Create.
The following section describes the key parameters. For more information about how to configure other parameters, see How to perform basic operations on an Ingress in the ACK console.
- Name: Enter a name for the Ingress. The name is set to ingress-demo in this example.
- Rules: Enter a custom domain name in the Domain field and enter the path /nginx in the Path field. Set Name in the Services section to the name of the Service that you created in Step 2: Release the NGINX application and use the automatically matched port 80 for Port.
On the Ingresses page, obtain the IP address of ingress-demo in the Endpoint column. Enter the endpoint IP address in the address bar of your browser. If the following page is displayed, it indicates that the Ingress is created.

Step 4: View the access log of the NGINX application

Log on to the ACK console.
In the left-side navigation pane of the ACK console, click Clusters.
On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
In the left-side navigation pane, click Cluster Information.
On the page that appears, click the Cluster Resources tab, find Log Service Project, and then click its ID to check the Logstore.
On the Logstores tab, select log-nginxvarlog to view the latest access log of the application.
