Question

我已经部署了两个docker容器，它们托管了两个部署在Jetty中的REST服务。

Container 1 hosts service 1 and it Listens to 7070
Container 2 hosts service 2 and it  Listens to 9090

终点： -

service1:
/ping
/service1/{param}

service2:
/ping
/service2/callService1

curl -X GET http://localhost:7070/ping [Works]
curl -X GET http://localhost:7070/service1/hello [Works]
curl -X GET http://localhost:9090/ping [Works]

我已经按照以下方式配置容器：

http://localhost:9090/serivce2/callService1 
calls 
http://localhost:7070/service1/hello

这会抛出连接拒绝异常。这是我的配置。

docker-compose.yml
------------------
service1: 
  build: microservice/
  ports: 
    - "7070:7070"
  expose:
    - "7070"
service2:
 build: microservice_link/
 ports:
 - "9090:9090"
 expose: 
 - "9090"
 links:
 - service1

service1 Dockerfile
-------------------
FROM localhost:5000/java:7
COPY ./target/service1.jar /opt
WORKDIR /opt
ENTRYPOINT ["java", "-jar", "service1.jar","7070"]
CMD [""]

service2 Dockerfile
-------------------
FROM localhost:5000/java:7
COPY ./target/service2.jar /opt
WORKDIR /opt
ENTRYPOINT ["java", "-jar", "service2.jar","9090"]
CMD [""]

问题： -

我正在尝试从容器2访问容器1中部署的端点。但是，我得到连接拒绝异常。我尝试在容器2中暴露端口7070.这没有用。

Answer 1

curl http://service1:7070/

使用 - host1_name:inner_port_of_host1

该主机在容器 2 中称为“service1”。将其用作主机名，端口是 service1 容器中的内部端口侦听器。

如果您在 service1 上有一个快速服务器，请侦听端口 7070。

从另一个容器调用docker容器
