mongodb - 无法连接到配置的 mongo 实例(连接被拒绝)

Question

基于本指南:

https://docs.opsmanager.mongodb.com/current/tutorial/install-simple-test-deployment/

我正在安装 MongoDB 和 MongoDB Manager。我为每个应用程序创建了一个 docker 镜像，并在同一虚拟网络上启动它们:

docker network create --driver bridge mongo-network

与:

MongoDB:

 docker run -ti -d --network mongo-network -p 27017:27017 --name mongodb-container mongodb-image
 docker exec -ti -u mongod mongodb-container "mongod --port 27017 --dbpath /data/appdb --logpath /data/appdb/mongodb.log --wiredTigerCacheSizeGB 1 --fork"

并验证其已启动并运行:

$  docker exec -ti -u mongod mongodb-container tail -f /data/appdb/mongodb.log

MongoDB 管理器:

  docker run -ti -d --network mongo-network -p 8080:8080 --name mongodb-manager-container mongodb-manager-image  
  docker exec -ti -u root mongodb-manager-container "/opt/mongodb/mms/bin/mongodb-mms start"

以下错误消息:

       ]

对于 mongodb - 基于下面的建议 - 我现在正在使用:

/etc/mongod.conf:

# network interfaces
net:
  port: 27017
  #bindIp: 127.0.0.1  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
  bindIp: 0.0.0.0,::

对于 MongoDB 管理器，我在以下位置指定 mongodb 容器的名称:

/opt/mongodb/mms/conf/conf-mms.properties

#mongo.mongoUri=mongodb://127.0.0.1:27017/?maxPoolSize=150
#mongo.mongoUri=mongodb://0.0.0.0:27017/?maxPoolSize=150
mongo.mongoUri=mongodb://mongodb-container:27017/?maxPoolSize=150

我已经验证我可以通过以下方式从 mongodb-manager-container ping mongodb-container:

docker exec -it -u root mongodb-manager-container bash
[root@e23a34bf2161 /]# ping mongodb-container
PING mongodb-container (172.18.0.2) 56(84) bytes of data.

[root@e23a34bf2161 /]# 

我错过了什么？

编辑:

基于我现在尝试过的以下建议:

docker network create --driver bridge mongo-network
docker run -ti -d --network mongo-network -p 27017:27017 --name mongodb-container mongodb-image
# Copy modified version of mongod.conf file to container before starting mongodb    
docker cp mongod.conf mongodb-container:/etc/mongod.conf

docker exec -ti -u mongod mongodb-container "mongod --port 27017 --dbpath /data/appdb --logpath /data/appdb/mongodb.log --wiredTigerCacheSizeGB 1 --fork"
docker run -it --rm --net container:mongodb-container nicolaka/netshoot ss -lnt

这给出:

State    Recv-Q    Send-Q        Local Address:Port        Peer Address:Port    
LISTEN   0         128              127.0.0.11:36001            0.0.0.0:*       
LISTEN   0         128               127.0.0.1:27017            0.0.0.0:*   

不确定这是否是预期的/良好的输出以及为什么我需要从 nicolaka/netshoot 图像启动容器...

编辑2:

如下所示，如果我在命令行上传递:--bind_ip_all来启动mongod，它就可以工作:

docker exec -ti -u mongod mongodb-container "mongod --bind_ip_all --port 27017 --dbpath /data/appdb --logpath /data/appdb/mongodb.log --wiredTigerCacheSizeGB 1 --fork"

因此，当作为 docker 容器运行时，它似乎完全忽略 /etc/mongod.conf 文件，您需要在 docker exec 命令中指定所有选项:-(

Answer 1

容器名称上的 DNS 将解析为容器 IP。要使用该名称连接到 mongo，即使是从容器内部，您也需要让 mongo 监听所有接口(interface):

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0,::
