部署Consul集群在Kubernetes(K8s)上,可以按照以下步骤进行操作:

  1. 创建一个Consul配置文件:创建一个名为consul-config.yaml的文件,并将以下内容复制到其中:
apiVersion: v1
kind: ConfigMap
metadata:
  name: consul-config
data:
  server.hcl: |
    datacenter = "dc1"
    data_dir = "/consul/data"
    log_level = "INFO"
    enable_syslog = true
    performance {
      raft_multiplier = 1
    }
  1. 创建一个Consul服务:创建一个名为consul.yaml的文件,并将以下内容复制到其中:
apiVersion: v1
kind: Service
metadata:
  name: consul
  labels:
    app: consul
spec:
  ports:
  - port: 8500
    name: http
  - port: 8600
    name: dns
    protocol: UDP
  selector:
    app: consul
---
apiVersion: v1
kind: Service
metadata:
  name: consul-dns
  labels:
    app: consul
spec:
  ports:
  - port: 53
    name: dns-tcp
    protocol: TCP
  - port: 53
    name: dns-udp
    protocol: UDP
  selector:
    app: consul
  1. 创建一个Consul部署:创建一个名为consul-deployment.yaml的文件,并将以下内容复制到其中:
apiVersion: apps/v1
kind: Deployment
metadata:
  name: consul
spec:
  replicas: 3
  selector:
    matchLabels:
      app: consul
  template:
    metadata:
      labels:
        app: consul
    spec:
      containers:
      - name: consul
        image: consul:latest
        args:
        - "agent"
        - "-config-dir=/consul/config"
        - "-client=0.0.0.0"
        - "-ui"
        - "-retry-join=consul-0.consul,consul-1.consul,consul-2.consul"
        ports:
        - containerPort: 8500
          name: http
        - containerPort: 8600
          name: dns
          protocol: UDP
        volumeMounts:
        - name: consul-config
          mountPath: /consul/config
        - name: consul-data
          mountPath: /consul/data
      volumes:
      - name: consul-config
        configMap:
          name: consul-config
      - name: consul-data
        emptyDir: {}
  1. 创建Consul集群:运行以下命令来创建Consul集群:
kubectl apply -f consul-config.yaml
kubectl apply -f consul.yaml
kubectl apply -f consul-deployment.yaml

以上步骤中,我们首先创建了一个ConfigMap来存储Consul的配置文件。然后创建了一个Service来公开Consul的HTTP和DNS端口。最后创建了一个Deployment来运行Consul的Pod,并将ConfigMap和EmptyDir挂载到Pod中。

请注意,上述步骤仅展示了部署Consul集群的基本步骤,实际操作中可能需要根据特定的环境和需求进行调整。
