nginx是否可以在ngninx反向代理docker上动态添加位置？

使用traefik解决了该问题，它允许我通过子目录将路由添加到容器，而无需修改构建配置。

这docker-compose.yml将是这样的：

version: '3.7'<font></font> services:<font></font> traefik:<font></font> image: traefik:v2.2.0<font></font> ports:<font></font> - "${FRONT_HTTP_PORT:-80}:80"<font></font> - "${TRAEFIK_PORT:-8080}:8080"<font></font> environment: <font></font> - TRAEFIK_LOG_LEVEL=DEBUG<font></font> - TRAEFIK_PROVIDERS_DOCKER_EXPOSEDBYDEFAULT=false<font></font> - TRAEFIK_PROVIDERS_DOCKER=true<font></font> - TRAEFIK_PROVIDERS_DOCKER_NETWORK=traefik01<font></font> - TRAEFIK_API_INSECURE=true<font></font> - TRAEFIK_ENTRYPOINTS_FRONT=true<font></font> - TRAEFIK_ENTRYPOINTS_FRONT_ADDRESS=:${FRONT_HTTP_PORT:-80}<font></font> volumes:<font></font> - /var/run/docker.sock:/var/run/docker.sock:ro<font></font> security_opt:<font></font> - label:type:docker_t<font></font> <font></font> frontend:<font></font> build: ./frontend<font></font> expose:<font></font> - 80<font></font> labels:<font></font> - "traefik.enable=true"<font></font> - "traefik.http.routers.frontend.entrypoints=front"<font></font> - "traefik.http.routers.frontend.rule=PathPrefix(`/frontend{regex:$$|/.*}`)"<font></font> - "traefik.http.routers.frontend.middlewares=frontend-stripprefix"<font></font> - "traefik.http.middlewares.frontend-stripprefix.stripprefix.prefixes=/frontend"<font></font> - "traefik.http.routers.frontend.priority=2"<font></font> # - "traefik.http.routers.frontend.priority=1"<font></font> # - "traefik.frontend.rule=Host:ctf.itasahobby.com"<font></font> stdin_open: true<font></font> <font></font> api:<font></font> build: ./api<font></font> expose: <font></font> - 80<font></font> links:<font></font> - database<font></font> labels:<font></font> - "traefik.enable=true"<font></font> - "traefik.http.routers.api.entrypoints=front"<font></font> - "traefik.http.routers.api.rule=PathPrefix(`/api{regex:$$|/.*}`)"<font></font> - "traefik.http.routers.api.middlewares=api-stripprefix"<font></font> - "traefik.http.middlewares.api-stripprefix.stripprefix.prefixes=/api"<font></font> - "traefik.http.routers.api.priority=2"<font></font> <font></font> database:<font></font> build: ./database<font></font> restart: always<font></font> networks:<font></font> default:<font></font> external:<font></font> name: testnetwork<font></font>

然后，要添加一个新容器，它必须包含相同的网络接口和标签，以便设置路由，例如：

version: '3.7'<font></font> services:<font></font> app2:<font></font> image: httpd:2.4.41-alpine<font></font> expose:<font></font> - 80<font></font> labels:<font></font> - "traefik.enable=true"<font></font> - "traefik.http.routers.app2.entrypoints=front"<font></font> - "traefik.http.routers.app2.rule=PathPrefix(`/app2{regex:$$|/.*}`)"<font></font> - "traefik.http.routers.app2.middlewares=app2-stripprefix"<font></font> - "traefik.http.middlewares.app2-stripprefix.stripprefix.prefixes=/app2"<font></font> networks:<font></font> default:<font></font> external:<font></font> name: testnetwork<font></font> <font></font> 
version: '3.7'<font></font> services:<font></font> app2:<font></font> image: httpd:2.4.41-alpine<font></font> expose:<font></font> - 80<font></font> labels:<font></font> - "traefik.enable=true"<font></font> - "traefik.http.routers.app2.entrypoints=front"<font></font> - "traefik.http.routers.app2.rule=PathPrefix(`/app2{regex:$$|/.*}`)"<font></font> - "traefik.http.routers.app2.middlewares=app2-stripprefix"<font></font> - "traefik.http.middlewares.app2-stripprefix.stripprefix.prefixes=/app2"<font></font> networks:<font></font> default:<font></font> external:<font></font> name: testnetwork<font></font> <font></font>
