Question

我一直在尝试使用docker-compose部署Jetty服务器，但我似乎无法从我的主机上获取我的应用程序端口。

这是我的compose.yml：

version: '3.3'

networks:
  app-network:

services:
  db:
    image: postgres:alpine
    command: postgres -c hba_file=/etc/pg_hba.conf
    environment:
      POSTGRES_USER: ******
      POSTGRES_PASSWORD: ******
    volumes:
      - postgresVolume:/var/lib/postgresql/data
      - ./pg_hba.conf:/etc/pg_hba.conf
    networks:
      app-network:
        aliases:
          - mydb

  app:
    build: .
    restart: always
    ports:
      - "7001:7001"
    depends_on:
      - db
    networks:
      - app-network

volumes:
  postgresVolume:

当我跑步时：

docker-compose up --build

一切都很好。但我似乎无法从我的主人那里访问我的api：

curl -H "Content-Type: application/json" -X POST -d '{"username":"user","password":"superPass"}' http://localhost:7001/user/ --trace-ascii ./dump

我明白了：

== Info:   Trying ::1...
== Info: TCP_NODELAY set
== Info: Connected to localhost (::1) port 7001 (#0)
=> Send header, 136 bytes (0x88)
0000: POST /user/ HTTP/1.1
0016: Host: localhost:7001
002c: User-Agent: curl/7.58.0
0045: Accept: */*
0052: Content-Type: application/json
0072: Content-Length: 42
0086:

0000: {"username":"user","password":"superPass"}
== Info: upload completely sent off: 42 out of 42 bytes
== Info: Empty reply from server
== Info: Connection #0 to host localhost left intact

运行

iptables -t nat -L -n

给出：

Chain POSTROUTING (policy ACCEPT)

编辑：

正在运行nmap localhost

Starting Nmap 7.60 ( https://nmap.org ) at 2018-02-08 12:09 CET
Nmap scan report for localhost (127.0.0.1)
Host is up (0.000055s latency).
Other addresses for localhost (not scanned): ::1
Not shown: 998 closed ports
PORT     STATE SERVICE
5432/tcp open  postgresql
7001/tcp open  afs3-callback

Nmap done: 1 IP address (1 host up) scanned in 0.03 seconds

对我来说这两件事似乎都没问题。

docker-compose ps

似乎也是正确的：

      Name                     Command               State           Ports
-----------------------------------------------------------------------------------
app_1   java -server -Xms2g -Xmx2g ...   Up      0.0.0.0:7001->7001/tcp
db_1    docker-entrypoint.sh postg ...   Up      5432/tcp

我的Jetty服务器似乎正在侦听正确的IP和端口：

2018-02-07 18:47:34.379 [main] INFO  o.e.jetty.server.AbstractConnector - Started ServerConnector@62452cc9{HTTP/1.1,[http/1.1, h2c]}{0.0.0.0:7001}

有没有人知道我做错了什么？我正在运行Arch Linux，

docker-compose version


docker-compose version 1.18.0, build unknown
docker-py version: 2.7.0
CPython version: 3.6.4
OpenSSL version: OpenSSL 1.1.0g  2 Nov 2017

好吧...... Jetty对我来说是错误的。我没想到这一点，但只是将我的HTTP服务器实现更改为Netty解决了这个问题，而没有修改我的代码或配置。

也许我应该通知Jetty这个？
