Using kubectl to Create an ELB Ingress¶
Scenario¶
This section uses an Nginx workload as an example to describe how to create an ELB ingress using kubectl.
If no load balancer is available in the same VPC, CCE can automatically create a load balancer when creating an ingress. For details, see Creating an Ingress - Automatically Creating a Load Balancer.
If a load balancer is available in the same VPC, perform the operation by referring to Creating an Ingress - Interconnecting with an Existing Load Balancer.
Prerequisites¶
An ingress provides network access for backend workloads. Ensure that a workload is available in a cluster. If no workload is available, deploy a sample Nginx workload by referring to Creating a Deployment, Creating a StatefulSet, or Creating a DaemonSet.
A NodePort Service has been configured for the workload. For details about how to configure the Service, see NodePort.
Dedicated load balancers must be the application type (HTTP/HTTPS) supporting private networks (with a private IP).
Ingress Description of networking.k8s.io/v1¶
In CCE clusters of v1.23 or later, the ingress version is switched to networking.k8s.io/v1.
Compared with v1beta1, v1 has the following differences in parameters:
The ingress type is changed from kubernetes.io/ingress.class in annotations to spec.ingressClassName.
The format of backend is changed.
The pathType parameter must be specified for each path. The options are as follows:
ImplementationSpecific: The matching method depends on Ingress Controller. The matching method defined by ingress.beta.kubernetes.io/url-match-mode is used in CCE, which is the same as v1beta1.
Exact: exact matching of the URL, which is case-sensitive.
Prefix: matching based on the URL prefix separated by a slash (/). The match is case-sensitive, and elements in the path are matched one by one. A path element refers to a list of labels in the path separated by a slash (/).
Creating an Ingress - Automatically Creating a Load Balancer¶
The following describes how to run the kubectl command to automatically create a load balancer when creating an ingress.
Use kubectl to connect to the cluster. For details, see Connecting to a Cluster Using kubectl.
Create a YAML file named ingress-test.yaml. The file name can be customized.
vi ingress-test.yaml
Note
Starting from cluster v1.23, the ingress version is switched from networking.k8s.io/v1beta1 to networking.k8s.io/v1. For details about the differences between v1 and v1beta1, see Ingress Description of networking.k8s.io/v1.
Example of a shared load balancer (public network access) for clusters of v1.23 or later:

CCE allows you to connect to an existing load balancer when creating an ingress.
Note
Existing dedicated load balancers must be the application type (HTTP/HTTPS) supporting private networks (with a private IP).
If the cluster version is 1.23 or later, the YAML file configuration is as follows:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:

annotations:
kubernetes.io/elb.id: <your_elb_id> # Replace it with the ID of your existing load balancer.

On the Summary tab page, find and copy the ID. |
kubernetes.io/elb.ip | Yes | String | This parameter indicates the service address of a load balancer. The value can be the public IP address of a public network load balancer or the private IP address of a private network load balancer. |
Configuring HTTPS Certificates¶
Ingress supports TLS certificate configuration and secures your Services with HTTPS.
Note
If HTTPS is enabled for the same port of the same load balancer of multiple ingresses, you must select the same certificate.
Use kubectl to connect to the cluster. For details, see Connecting to a Cluster Using kubectl.
Run the following command to create a YAML file named ingress-test-secret.yaml (the file name can be customized):
vi ingress-test-secret.yaml
The YAML file is configured as follows:
apiVersion: v1 data: tls.crt: LS0******tLS0tCg== tls.key: LS0tL******0tLS0K kind: Secret metadata: annotations: description: test for ingressTLS secrets name: ingress-test-secret namespace: default type: IngressTLS
Note
In the preceding information, tls.crt and tls.key are only examples. Replace them with the actual files. The values of tls.crt and tls.key are Base64-encoded.
Create a secret.
kubectl create -f ingress-test-secret.yaml
If information similar to the following is displayed, the secret is being created:
secret/ingress-test-secret created
View the created secrets.
kubectl get secrets
If information similar to the following is displayed, the secret has been created successfully:
NAME TYPE DATA AGE ingress-test-secret IngressTLS 2 13s
Create a YAML file named ingress-test.yaml. The file name can be customized.
vi ingress-test.yaml
Note
Default security policy (kubernetes.io/elb.tls-ciphers-policy) is supported only in clusters of v1.17.17 or later.
The following uses the automatically created load balancer as an example. The YAML file is configured as follows:
For clusters of v1.21 or earlier:

Using HTTP/2¶
Ingresses can use HTTP/2 to expose services. Connections from the load balancer proxy to your applications use HTTP/1.X by default. If your application is capable of receiving HTTP/2 requests, you can add the following field to the ingress annotation to enable the use of HTTP/2:
`kubernetes.io/elb.http2-enable: 'true'`
The following shows the YAML file for associating with an existing load balancer:

Table 6 HTTP/2 parameters
Parameter | Mandatory | Type | Description |
---|---|---|---|
kubernetes.io/elb.http2-enable | No | Bool | Whether HTTP/2 is enabled. Request forwarding using HTTP/2 improves the access performance between your application and the load balancer. However, the load balancer still uses HTTP 1.X to forward requests to the backend server. This parameter is supported in clusters of v1.19.16-r0, v1.21.3-r0, and later versions. Options:
Note: HTTP/2 can be enabled or disabled only when the listener uses HTTPS. This parameter is invalid and defaults to false when the listener protocol is HTTP. |
Configuring the Server Name Indication (SNI)¶
SNI allows multiple TLS-based access domain names to be provided for external systems using the same IP address and port number. Different domain names can use different security certificates.
Note
Only one domain name can be specified for each SNI certificate. Wildcard-domain certificates are supported.
Security policy (kubernetes.io/elb.tls-ciphers-policy) is supported only in clusters of v1.17.11 or later.
You can enable SNI when the preceding conditions are met. The following uses the automatic creation of a load balancer as an example. In this example, sni-test-secret-1 and sni-test-secret-2 are SNI certificates. The domain names specified by the certificates must be the same as those in the certificates.

Accessing Multiple Services¶
Ingresses can route requests to multiple backend Services based on different matching policies. The spec field in the YAML file is set as below. You can access www.example.com/foo, www.example.com/bar, and foo.example.com/ to route to three different backend Services.
Important
The URL registered in an ingress forwarding policy must be the same as the URL exposed by the backend Service. Otherwise, a 404 error will be returned.

rules:
- host: 'www.example.com'
http:
paths:
- path: '/foo'

servicePort: 80
property:
ingress.beta.kubernetes.io/url-match-mode: STARTS_WITH
Interconnecting with HTTPS Backend Services¶
Ingress can interconnect with backend services of different protocols. By default, the backend proxy channel of an ingress is an HTTP channel. To create an HTTPS channel, add the following configuration to the annotations field:
kubernetes.io/elb.pool-protocol: https
Important
This feature only applies to clusters of v1.23.8, v1.25.3, and later.
Ingress can interconnect with HTTPS backend services only when dedicated load balancers are used.
When interconnecting with HTTPS backend services, set Client Protocol of ingress to HTTPS.
An ingress configuration example is as follows:
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-test
namespace: default
annotations:
kubernetes.io/elb.port: '443'
kubernetes.io/elb.id: <your_elb_id> # In this example, an existing dedicated load balancer is used. Replace its ID with the ID of your dedicated load balancer.
