Docker Compose yml 小技巧
- 設定多個 hosts
version: '3.8'
x-hosts: &x-hosts
- 'mysql:172.29.0.3'
- 'app:172.29.0.4'
- 'influxdb:172.29.0.5'
...
app:
extra_hosts: *x-hosts
- build with context
...
app:
build:
context: .
dockerfile: ./.docker/Dockerfile.xxx-xx
- connect other network
- bridge
# docker-compose-1.yml
version: '3.7'
...
services:
svc1:
networks:
- custom_name
networks:
custom_name: # 這邊是類似 namespace 的概念
driver: bridge
# docker-compose-2.yml
version: '3.7'
...
services:
svc1:
networks:
- mynet
...
networks:
mynet:
external:
name: folder_custom_name
- pre-existing
version: '3.7'
...
services:
svc1:
networks:
- network_name
# 只要指定 external true 即可
networks:
network_name:
external: true
- virtual volume 用他的好處是不用特別綁定路徑，且也可避免 host 真的要裝該服務時路徑衝突問題，比較適用的場景為一次只有一個專案的情境
...
services:
postgres:
image: postgres:13.2
restart: unless-stopped
- POSTGRES_USER=root
- POSTGRES_PASSWORD=root
volumes:
- postgres:/var/lib/postgresql/data
volumes:
postgres:
