容器(qi)在啟動之后，如果需要(yao)容器(qi)的(de)/etc/hosts 去綁定其它域名與IP的(de)，我總結了docker,compose,k8s的(de)實現方式 ，總結如下

docker run

docker run --add-host=kafka1:192.168.1.10 

docker-compose

extra_hosts:
 - "kafka1:192.168.1.10"
 - "kafka2:192.168.1.11"

k8s

kind: Deployment
apiVersion: apps/v1
spec:
  template:
    spec:
      hostAliases:    
        - ip: "192.168.1.10"
          hostnames: ["kafka1"]
        - ip: "192.168.1.11"
          hostnames: ["kafka2"]
