[英]How to use Docker container name for URL endpoint in React app when building app with docker-compose?
[英]how to use networking when building docker-compose?
我想構建我的應用程序的 docker 映像。 構建過程(測試)需要其他服務(db)。 好像我的應用無法連接到數據庫
我設法使用簡單的小圖像復制了這個問題。
dockerfile(它只是試圖到達 web 端點)
from alpine:3.10.2
run wget web:8080
cmd ["sh"]
docker-compose
version: "3.7"
services:
web:
image: tutum/hello-world
ports:
- "8080:80"
app:
build: .
depends_on:
- web
在docker-compose up
期間我得到了
wget: bad address 'web:8080'
ERROR: Service 'app' failed to build: The command '/bin/sh -c wget web:8080' returned a non-zero code: 1
在構建過程中如何訪問其他容器?
您需要在撰寫中使用network
作為主機:
build:
network: host
並使用localhost:port
訪問它
例子:
docker-compose:
version: "3.7"
services:
web:
image: tutum/hello-world
ports:
- "8080:80"
app:
build:
context: .
network: host
depends_on:
- web
Dockerfile:
FROM alpine:3.10.2
RUN wget localhost:8080
CMD ["sh"]
運行web
:
docker-compose up -d --build web
運行app
:
docker-compose up -d --build app
output:
Building app
