Mongo-Express 由 Docker-Compose 启动导致错误 [MongoError]：首次连接时无法连接到服务器 [mongo:27017]
Mongo-Express started by Docker-Compose causing Error [MongoError]: failed to connect to server [mongo:27017] on first connect
场景：我想从同一个 docker-compose 开始 Mongo 和 Mongo-Express。
我只从 docker-compose 开始 mongodb 没问题。当我尝试 link Mongo-Express 到 Mongo 数据库服务时出现问题。
我不确定我是否缺少 docker-compose 或 mongo-express 设置中的某些配置。我不认为问题是 Mongo 设置的一部分。顺便说一句，我在下面粘贴了整个 docker-compose 及其输出。
从下面的日志中我可以看到没有引发 Mongo 的问题。 mongo-express 尝试连接到 Mongo 服务时出现一些问题，可能是因为我没有正确设置 link。最重要的是，我的 Spring Webflux 已成功连接到 Mongo 具有以下属性的数据库。该问题仅限于 mongo-express 达到 mongodb.
application.yml 允许 Spring 数据（spring-boot-starter-data-mongodb-reactive）成功连接到这样的 MongoDb

注意它已达到最大尝试次数，5/5:
"mongo-express_1 | 3 月 18 日星期三 22:06:18 UTC 2020 重试连接到 mongo:27017 (5/5)"
关于这个问题的 Whosebug 上有很多文章，许多人试图猜测多种答案。我能够通过更改 max_tries 的数量来解决我的问题，但这需要 patch in the mongo-express-docker project.
我遇到了同样的问题
我使用了 docker-compose 来自 mongo docker official image documentation
的示例
# Use root/example as user/password credentials
version: '3.1'
services:
mongo:
image: mongo
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root

mongo-express:
image: mongo-express
restart: always
ports:
- 8081:8081
environment:

我在最后添加 depends_on: - mongo 解决了我的问题
# Use root/example as user/password credentials
version: '3.1'
services:
mongo:
image: mongo
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root

场景：我想从同一个 docker-compose 开始 Mongo 和 Mongo-Express。
我只从 docker-compose 开始 mongodb 没问题。当我尝试 link Mongo-Express 到 Mongo 数据库服务时出现问题。
我不确定我是否缺少 docker-compose 或 mongo-express 设置中的某些配置。我不认为问题是 Mongo 设置的一部分。顺便说一句，我在下面粘贴了整个 docker-compose 及其输出。
从下面的日志中我可以看到没有引发 Mongo 的问题。 mongo-express 尝试连接到 Mongo 服务时出现一些问题，可能是因为我没有正确设置 link。最重要的是，我的 Spring Webflux 已成功连接到 Mongo 具有以下属性的数据库。该问题仅限于 mongo-express 达到 mongodb.
application.yml 允许 Spring 数据（spring-boot-starter-data-mongodb-reactive）成功连接到这样的 MongoDb

根据 docs，您应该使用名为 ME_CONFIG_MONGODB_SERVER
的 ENVME_CONFIG_MONGODB_SERVER : MongoDB container name. Use comma delimited list of host names for replica sets.
services:

- 8081:8081
environment:

注意它已达到最大尝试次数，5/5:
"mongo-express_1 | 3 月 18 日星期三 22:06:18 UTC 2020 重试连接到 mongo:27017 (5/5)"
关于这个问题的 Whosebug 上有很多文章，许多人试图猜测多种答案。我能够通过更改 max_tries 的数量来解决我的问题，但这需要 patch in the mongo-express-docker project.
我遇到了同样的问题
我使用了 docker-compose 来自 mongo docker official image documentation
的示例# 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
我在最后添加 depends_on: - mongo 解决了我的问题
# Use root/example as user/password credentials
version: '3.1'
services:
mongo:
image: mongo
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root
