由于默認(rèn)的bridge橋接網(wǎng)絡(luò)，重啟容器后會(huì)改變ip地址。在一些場(chǎng)景下我們希望固定容器IP地址。
docker-compose是docker的一個(gè)編排工具，相對(duì)于命令模式創(chuàng)建網(wǎng)絡(luò)，容器等。使用配置文件相對(duì)來(lái)說(shuō)更方便，可追溯問(wèn)題。
直接粘貼docker-compose.yml文件
version: '2'
services:
nginx:
image: nginx:1.13.12
container_name: nginx
restart: always
tty: true
networks:
extnetwork:
ipv4_address: 172.19.0.2
networks:
extnetwork:
ipam:
config:
- subnet: 172.19.0.0/16
gateway: 172.19.0.1
說(shuō)明：
- gateway是網(wǎng)關(guān)地址
- subnet是網(wǎng)絡(luò)號(hào)段
- extnetwork是自定義的網(wǎng)絡(luò)名稱
上面配置中我們的nginx容器固定ip為172.19.0.2
示例，自定義網(wǎng)絡(luò)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
