由于默认的bridge桥接网络，重启容器后会改变ip地址。在一些场景下我们希望固定容器IP地址。
docker–compose是docker的一个编排工具，相对于命令模式创建网络，容器等。使用配置文件相对来说更方便，可追溯问题。
直接粘贴docker-compose.yml文件
| version: ‘2'
services: image: nginx:1.13.12 container_name: nginx restart: always tty: true ipv4_address: 172.19.0.2 networks: extnetwork: ipam: config: – subnet: 172.19.0.0/16 gateway: 172.19.0.1 |
说明：
gateway是网关地址
subnet是网络号段
extnetwork是自定义的网络名称
上面配置中我们的nginx容器固定ip为172.19.0.2
示例，自定义网络模式：
| version: ‘2'
services: nginx: image: nginx:1.13.12 container_name: nginx restart: always networks: extnetwork: ports: – 80:80 volumes: – ‘/nginx/conf.d:/etc/nginx/conf.d' nginx2: image: nginx:1.13.12 container_name: nginx2 restart: always networks: extnetwork: ipv4_address: 172.19.0.2
db: image: mysql:5.7 container_name: db volumes: – /var/lib/mysql:/var/lib/mysql restart: always networks: extnetwork: ports: – 3306:3306 environment: MYSQL_ROOT_PASSWORD: wordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress
wordpress: image: wordpress:latest container_name: wordpress depends_on: – db ports: – “8000:80” restart: always networks: extnetwork: environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_NAME: wordpress WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress networks: extnetwork: ipam: config: – subnet: 172.19.0.0/16 gateway: 172.19.0.1 |
