官方 Mongo Docker Image 页面上提供的 YAML 在 CentOS 上不起作用

如何解决官方 Mongo Docker Image 页面上提供的 YAML 在 CentOS 上不起作用

给定的 yml（最初提供 :help \magic）：

# Use root/example as user/password credentials
version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

在我的 windows 和 macOS docker 环境中可以正常工作。但是当我在 CentOS docker 环境中运行相同的 yml 时，mongo express 无法连接到 mongodb 服务。因此 mongo express 不会显示在浏览器中的 localhost:8081。我该如何解决这个问题？

编辑：

我想在将“mongo”映射到相应的容器 IP 地址时，DNS 似乎存在问题。我无法解释原因，因为这在 Windows 上不是问题。

这是mongo（mongodb）服务的日志：

解决方法

试试这个：

# Use root/example as user/password credentials
version: '3.1'

services:

  mongo:
    image: mongo
    container_name: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    ports:
      - 27017:27017

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
    links:
      - "mongo"
    depends_on:
      - "mongo"
,

如果你愿意，请试试这个（工作示例）：

version: '3'

services:
  mongo:
    image: mongo
    restart: always
    container_name: my_mongo
    ports:
    - "27017:27017"
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    volumes:
    - ./data/db:/data/db
    - ./data/configdb:/data/configdb

  mongo-express:
    image: mongo-express
    restart: always
    container_name: my_mongo_express
    ports:
    - "8081:8081"
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_BASICAUTH_USERNAME: user
      ME_CONFIG_BASICAUTH_PASSWORD: example
    depends_on:
      - mongo
    
volumes:
  node_modules:

如果您认为那里有问题，您也可以尝试使用不同的名称或端口公开 Mongo 服务。在这种情况下，您还必须相应地更改 MongoExpress 服务中的相应变量（ME_CONFIG_MONGODB_SERVER 和 ME_CONFIG_MONGODB_PORT） - 有关可能配置的详细信息 here

无论哪种方式，是否正确创建了涉及这两个服务的网络？

,

通常 mongo-express 的重试次数是 5，也许数据库在 docker-centos-env 上的连接时间比 windows/macos 多。如果你这样做，你可以检查数据库是否工作{{1 }} ，那么你可以做一些像 docker exec -it nameofmongocontainer mongo -uroot -pexample

在 mongo-express 设法与数据库建立连接之前，你提到了它在我的 docker windows env 上发生的 DNS 问题 3 次，因此它不是 centos docker env 独有的 ..

潜在修复：您可以将脚本添加到 docker-compose 文件中，该文件可以将重试次数增加到 20 .. 这是来自 here 的示例（将 docker-entrypoint.sh 脚本保存在与你的 docker-compose 文件 )

show dbs;

docker-compose 文件将是

#!/bin/bash
set -eo pipefail
# This is a very small modification of the original docker script taken from
# https://github.com/mongo-express/mongo-express-docker/blob/master/docker-entrypoint.sh
# with only change being the modified value of max_tries=20 instead of original 5,# to give the main mongodb container enough time to start and be connectable to.
# Also,see https://docs.docker.com/compose/startup-order/

# if command does not start with mongo-express,run the command instead of the entrypoint
if [ "${1}" != "mongo-express" ]; then
    exec "$@"
fi

function wait_tcp_port {
    local host="$1" port="$2"
    local max_tries=20 tries=1

    # see http://tldp.org/LDP/abs/html/devref1.html for description of this syntax.
    while ! exec 6<>/dev/tcp/$host/$port && [[ $tries -lt $max_tries ]]; do
        sleep 10s
        tries=$(( tries + 1 ))
        echo "$(date) retrying to connect to $host:$port ($tries/$max_tries)"
    done
    exec 6>&-
}

# if ME_CONFIG_MONGODB_SERVER has a comma in it,we're pointing to a replica set (https://github.com/mongo-express/mongo-express-docker/issues/21)
if [[ "$ME_CONFIG_MONGODB_SERVER" != *,* ]]; then
    # wait for the mongo server to be available
    echo Waiting for ${ME_CONFIG_MONGODB_SERVER}:${ME_CONFIG_MONGODB_PORT:-27017}...
    wait_tcp_port "${ME_CONFIG_MONGODB_SERVER}" "${ME_CONFIG_MONGODB_PORT:-27017}"
fi

# run mongo-express
exec node app

也许是 Centos 的问题？ 您可以做的是分别执行这些步骤

  1. version: '3.1' services: mongo: image: mongo restart: always environment: MONGO_INITDB_ROOT_USERNAME: root MONGO_INITDB_ROOT_PASSWORD: example mongo-express: image: mongo-express restart: always ports: - 8081:8081 environment: ME_CONFIG_MONGODB_ADMINUSERNAME: root ME_CONFIG_MONGODB_ADMINPASSWORD: example volumes: - ./docker-entrypoint.sh:/docker-entrypoint.sh
  2. docker network create mongo-test
  3. docker run -d --name mongo -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=example --net mongo-test mongo
