docker - 使用 Traefik 和 Docker Compose 在同一主机上提供 2 个服务,但路由不同
问题描述
我有 2 个前端应用程序,都由 Nginx 在端口 80 提供服务
app-login
app-contacts
我正在尝试使用 Docker Compose 配置 Traefik 以实现此目的:
- 两个应用程序都在同一主机上提供服务(例如 abc.com 或 localhost:4000)
app-login
将从 localhost:4000/login(或 abc.com/login)访问app-contacts
将从 localhost:4000/contacts(或 abc.com/contacts)访问
但问题是:它不适用于我目前所做的。
以下是 2Dockerfile
个应用程序中的 2 个,以及docker-compose.yml
app-login
Dockerfile:
# build stage
FROM node:lts-alpine as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
# production stage
FROM nginx:stable-alpine as production-stage
COPY --from=build-stage /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
app-contacts
Dockerfile:(有点复杂,但和登录应用类似)
### STAGE 1: Build the AngularJS app ###
FROM node:lts-alpine as build-stage
RUN apk --no-cache add git
WORKDIR /app
COPY package.json /app/
RUN npm install
COPY . .
# Production mode build
RUN npm run build:prod
### STAGE 2: Add Nginx for hosting the AngularJS app ###
FROM nginx:stable-alpine as production-stage
# Removes the default nginx html files
RUN rm -rf /usr/share/nginx/html/*
# Copy the bundle
COPY --from=build-stage /app/dist /usr/share/nginx/html
# Copy the default nginx.conf
COPY --from=build-stage /app/nginx.conf /etc/nginx/conf.d/default.conf
VOLUME ["/usr/share/nginx/html/env"]
EXPOSE 80
# Copy .env file and shell script to container
WORKDIR /usr/share/nginx/html
COPY ./scripts/generate_env.sh .
COPY .env .
# Add bash
RUN apk add --no-cache bash
# Make our shell script executable
RUN chmod +x generate_env.sh
# Start Nginx server
CMD ["/bin/bash", "-c", "/usr/share/nginx/html/generate_env.sh && nginx -g \"daemon off;\""]
docker-compose.yml
version: '3'
services:
reverse-proxy:
# The official v2 Traefik docker image
image: traefik:v2.2
# Enables the web UI and tells Traefik to listen to docker
command: --api.insecure=true --providers.docker
ports:
# The HTTP port
- "80:80"
# The Web UI (enabled by --api.insecure=true)
- "8080:8080"
volumes:
# So that Traefik can listen to the Docker events
- /var/run/docker.sock:/var/run/docker.sock
app-login:
image: app-login
labels:
- "traefik.http.routers.app-login.rule=Path(/login)"
app-contacts:
image: app-contacts
labels:
- "traefik.http.routers.app-contacts.rule==Path(/contacts)"
不知道我哪里做错了。
我搜索了谷歌,在某个地方我看到人们正在使用https://www.getambassador.io/这个堆栈,但我也不知道如何配置它。
谢谢你。
解决方案
我发现了问题
基于此链接https://docs.traefik.io/routing/routers/#rule
Backticks or Quotes?
To set the value of a rule, use backticks ` or escaped double-quotes \".
Single quotes ' are not accepted as values are Golang's String Literals.
所以规则必须是
“traefik.http.routers.app-contacts.rule==Path(`/contacts`)”
