这是我的问题

# docker exec -ti root_web_1 bash
[root@ca32f79bdc14]# curl couchdb:5984
curl: (7) Failed to connect to couchdb port 5984: Connection refused
[root@ca32f79bdc14]# curl redis:6379  
-ERR wrong number of arguments for 'get' command
-ERR unknown command 'Host:'
-ERR unknown command 'User-Agent:'
-ERR unknown command 'Accept:'
^C

题

为什么我不能访问ouchdb：5984？

背景

当我在沙发床容器中时,我可以卷曲localhost：5984,它会响应,并且netstat -nl给我

Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 127.0.0.1:5984          0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.11:35300        0.0.0.0:*               LISTEN
udp        0      0 127.0.0.11:51267        0.0.0.0:*

并且Dockerfile包含EXPOSE 5984,但是从Web容器执行curl benchdb：5984时,连接被拒绝.

当我对redis进行相同操作时,卷曲redis：6379它会响应,并且netstat -nl会给出

Proto Recv-Q Send-Q Local Address           Foreign Address         State      
tcp        0      0 127.0.0.11:46665        0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN
tcp6       0      0 :::6379                 :::*                    LISTEN
udp        0      0 127.0.0.11:49518        0.0.0.0:*

这是couchdb Dockerfile

FROM fedora:25
RUN dnf -y update
RUN dnf -y install couchdb
EXPOSE 5984
CMD ["/usr/bin/couchdb"]

这是docker-compose.yml.

version: '2'
networks:
  revproxynet:
    external: true
services:
  web:
    images: nginx
    networks:
      - revproxynet
  redis:
    image: redis
    networks:
      - revproxynet
  couchdb:
    build: /docker/couchdb/
    networks:
      - revproxynet

使用docker network create revproxynet创建网络.

解决方法:

在/etc/couchdb/local.ini中,您需要具有

[httpd]
bind_address = 0.0.0.0

它会工作.
