我在访问另一个集装箱中的一个集装箱路线时遇到问题。例如,我有两个名为 user-service 和 api-gateway 的微服务。我正在尝试访问 api网关中的用户服务路由。
I'm facing an issue to access one container route in another container. For example i have two micro services called user-service and api-gateway. I'm trying to access user-service route in api-gateway.
我的 api-gateway 文件可能如下所示
const userServiceProxy = httpProxy(localhost:8093); this.app.post('/admin/register', async(req, res) => { userServiceProxy(req, res); });api-gateway 在端口8080上运行
api-gateway is running on port 8080
我的用户服务文件可能如下所示
app.post('/admin/register', function (req, res) { res.send('POST request') })当我使用端口8080通过 api-gateway 访问路由时,我无法调用该路由,但是当我尝试使用端口8093我可以看到结果。
when i access route through api-gateway with the port 8080 i couldn't able to call the route but when i tried to access with the port 8093 i can able to see the result.
我的 docker-compose 文件可能如下所示
version: '3' services: api-gateway: container_name: api-gateway build: './api-gateway' ports: - "8080:8080" links: - user-service user-service: build: ./user-service container_name: user-service ports: - "8093:8093"任何帮助都会b非常感谢,谢谢!!
Any help would be greatly appreciated, Thanks in advance!
推荐答案只需向您添加docker-compose文件的网络规范以使用自定义网桥网络。
just add a network specification to you docker-compose file to use a custom bridge network.

something like that might work for you
version: '3' services: api-gateway: container_name: api-gateway build: './api-gateway' ports: - "8080:8080" networks: - mynet user-service: build: ./user-service container_name: user-service ports: - "8093:8093" networks: - mynet networks: mynet: driver: bridge ipam: driver: default根据docker中指定的端口和服务,现在可以进行以下连接:
according to your specified ports and services in your docker-compose the following connections are now possible:
- api网关容器: user-service:8093
- 用户服务容器: api-网关:8080
- api-gateway container: user-service:8093
- user-service container: api-gateway:8080
如果我做对了,您的api网关现在应该是:
if i get it right, your api-gateway would now be:
const userServiceProxy = httpProxy(user-service:8093); this.app.post('/admin/register', async(req, res) => { userServiceProxy(req, res); });在docker网络内部,您可以直接从其他容器访问端口(无需指定端口-映射到您的主机)。因此,可能不需要您的端口映射之一。如果您仅通过api-gateway而不是直接访问用户服务,则可以在docker-compose文件(用户服务块)中删除端口规范。您的用户服务将只能通过api-gateway访问。可能正是您想要的。
inside a docker network you can access the ports from other containers directly (no need to specify a port-mapping to your host). probably one of your port-mappings is therefore unnecessary. if you are accessing the user-service only via api-gateway and not directly you may remove the port specification in your docker-compose files (user-service block). your user-service would then be accessible only using the api-gateway. which is probably what you want.
