docker-compose 配置IP、hostname、hosts配置
配置IP
version: "3"
networks:
bd-network: # 声明网络
external: true
services:
kafka: # 服务名称
networks:
bd-network: # 连接的网络名称
ipv4_address: 172.2.0.102 # 配置IP
配置 主机名
version: "3"
services:
kafka: # 服务名称
hostname: kf # 主机名
配置hosts
下面的配置可以修改/etc/hosts文件: 追加zk 172.2.0.101 、kf 172.2.0.102
version: "3"
services:
kafka:
extra_hosts:
- "zk:172.2.0.101"
- "kf:172.2.0.102"
配置完成进入容器，可查看验证
$ sudo docker exec -it zk-singleton /bin/bash
$ cat /etc/hosts
完整例子
- 创建一个网络
$ sudo docker network create --driver=bridge --gateway=172.2.0.1 --subnet=172.2.0.0/16 bd-network
- 配置 单节点kafka、zookeeper，kafka通过主机名 访问zookeeper
version: "3"
networks: #声明网络
bd-network:
external: true
services:
zookeeper: # 服务名
image: 'bitnami/zookeeper:latest' # 镜像
container_name: zk-singleton # 容器名
hostname: zk # 主机名
networks:
bd-network:
ipv4_address: 172.2.0.101 # 定义容器ip
extra_hosts:
- "zk:172.2.0.101"
- "kf:172.2.0.102"
ports: # 宿主端口:容器端口映射
- '2181:2181'
environment: # 容器环境配置
- ALLOW_ANONYMOUS_LOGIN=yes
kafka:
image: 'bitnami/kafka:latest'
container_name: kf-singleton
hostname: kf
networks:
bd-network:
ipv4_address: 172.2.0.102
extra_hosts:
- "zk:172.2.0.101"
- "kf:172.2.0.102"
ports:
- '9192:9092'
environment:
- KAFKA_BROKER_ID=1
- ALLOW_PLAINTEXT_LISTENER=yes
- KAFKA_CFG_LISTENERS=PLAINTEXT://:9092
- KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://:9092
- KAFKA_CFG_ZOOKEEPER_CONNECT=zk:2181 # 通过主机名访问zookeeper
depends_on: # 依赖
- zookeeper
