Kubernetes Haproxy Deployment

my test cluster need to call kong that listen on haproxy-protocal mode, So I need Haproxy before them.

fiile: haproxy.cfg

defaults
 mode tcp
 timeout connect 8s
 timeout client 8h
 timeout server 8h

frontend kong_https
 mode tcp
 bind 0.0.0.0:443
 default_backend kong_https_backend

backend kong_https_backend
 mode tcp
 server kong1 10.16.51.21:443 check weight 1 send-proxy
 server kong2 10.16.51.22:443 check weight 1 send-proxy
 server kong3 10.16.51.23:443 check weight 1 send-proxy

file: haproxy-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: kong-haproxy
  name: kong-haproxy
spec:
  replicas: 2
  selector:
    matchLabels:
      app: kong-haproxy
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: kong-haproxy
    spec:
      securityContext:
        runAsUser: 0
      containers:
      - image: haproxy:2.7
        volumeMounts:
        - name: config-volume
          mountPath: /usr/local/etc/haproxy/haproxy.cfg
          subPath: haproxy.cfg
        name: haproxy
        resources:
          requests:
            cpu: 100m
            memory: 100Mi
      volumes:
        - name: config-volume
          configMap:
            name: haproxy1
status: {}

Then run:

$ k create configmap haproxy1  --from-file=haproxy.cfg
$ k apply -f haproxy-deploy.yaml
$ k create service  clusterip kong-haproxy --tcp=443:443

That’s all — hope it not permanent used.
