What is Ingress?

Ingress is a routing and load balancer that provides external services, and its essence is a nginx controller service.

Ingress classic data link map on k8s document:

Internet | [Ingress]-- |-|-- [Services] transform the blog to build Dockefile

First, the entire Hexo project is containerized to build Dockefile, which is deployed in the form of nginx + static resources (mainly to save memory CPU):

FROM nginx:1.13.0-alpineLABEL maintainer= "hexo-shikanon-blog" # load compiled files and visit COPY. / public / usr/share/nginx/html to build Deployment

Build a Deployment service and deploy it to kubernetes:

ApiVersion: apps/v1kind: Deploymentmetadata: name: nginx-hexo-blog-delopyment labels: webtype: staticblogspec: replicas: 2 selector: matchLabels: webtype: staticblog template: metadata: labels: webtype: staticblog function: blogspec: containers:-name: hexo-blog image: nginx-hexo-blog:0.0.1 ports:-containerPort: 80 build Service exposure service port

Build a Service exposed unified service port:

ApiVersion: v1kind: Servicemetadata: name: static-blogspec: selector: webtype: staticblog ports:-protocol: TCP port: 80 targetPort: 80 # deployment port

Here you create a Service object named "static-blog" that proxies the request to the Pod that uses the TCP port targetPort and has the label "webtype: staticblog".

View port information:

$kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT (S) AGE kubernetes ClusterIP 10.13.0.1 443/TCP 10d static-blog ClusterIP 10.13.83.44 80/TCP 8h

Test whether the port is accessible:

$curl-I 10.13.83.44 HTTP/1.1 200 OK Server: nginx/1.13.0 Date: Wed, 16 Oct 2019 16:51:13 GMT Content-Type: text/html Content-Length: 71636 Last-Modified: Mon, 29 Jul 2019 19:25:29 GMT Connection: keep-alive ETag: "5d3f4829-117d4" Accept-Ranges: bytes

Build an Ingress service

Finally, build the Ingress service to provide services and reverse proxies to the outside world:

ApiVersion: extensions/v1beta1kind: Ingressmetadata: name: reverse-proxy annotations: nginx.ingress.kubernetes.io/rewrite-target: / spec: rules:-host: www.shikanon.com http: paths:-backend: serviceName: static-blog servicePort: 80

Done!

Constructing HTTPS website to save key data with secret type object

The Secret object type is used to hold sensitive information, such as passwords, OAuth tokens, and ssh key, and ssh key is a classic application.

Secret parameter use case:

Kubectl create secret-hCreate a secret using specified subcommand.Available Commands: docker-registry Create a secret for use with a Docker registry generic Create a secret from a local file, directory or literal value tls Create a TLS secretUsage: kubectl create secret [flags] [options]

Create an Secret encrypted object:

Kubectl create secret tls shikanon-ssh-key-secret-cert=/home/shikanon/web/www/ssl/cert.pem-key=/home/shikanon/web/www/ssl/private.key

Modify Ingress:

ApiVersion: extensions/v1beta1kind: Ingressmetadata: name: reverse-proxy annotations: nginx.ingress.kubernetes.io/rewrite-target: / spec: rules:-host: www.shikanon.com http: paths:-backend: serviceName: static-blog servicePort: 80 tls:-hosts:-www.shikanon.com secretName: shikanon-ssh-key-secret

Note: an Ingress can only support one tls.
