1.  可以通过echo来写文件，用在shell脚本，或者自动化中。

echo "aaaaa" > fileName.txt

echo "bbbbb" >> fileName.txt

cat fileName.txt

aaaaa
bbbbb

2. 通过输入直接执行命令

echo "
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$2
  name: rewrite
  namespace: default
spec:
  rules:
  - host: rewrite.bar.com
    http:
      paths:
      - backend:
          serviceName: http-svc
          servicePort: 80
        path: /something(/|$)(.*)
" | kubectl create -f -

rewrite.bar.com/something rewrites to rewrite.bar.com/

rewrite.bar.com/something/ rewrites to rewrite.bar.com/

rewrite.bar.com/something/new rewrites to rewrite.bar.com/new

ingress中的重定向写法

echo "
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /projectname
    kubernetes.io/ingress.class: "nginx"
  name: ingress-name
  namespace: default
spec:
  rules:
    - host: aaa.bbb.com
      http:
        paths:
          - backend:
              serviceName: ccc-svc
              servicePort: 8080
            path: /projectname/api
  tls:
    - hosts:
        - aaa.bbb.com
      secretName: aaa-https-secret
" | kubectl create -f -
