db/mongoose.js 设置mongodb连接

但无论什么api容器都无法连接。我尝试将mongo uri设置为0.0.0.0:3001，但没有乐趣。我使用db.serverCmdLineOpts（）检查了用于在容器中启动mongo的配置设置。并且，命令bind_ip_all已经传递，因此mongo应该接受来自任何ip的连接。典型的问题是人们忘记用他们的mongo容器名替换localhost。如： mongodb://localhost:27017/TodoApp >> mongodb://mongodb:27017/TodoApp

但是，这已经完成了。太难堪了

嗯。我已经解决了。在本博客的帮助下-
您需要等待mongod在容器内完全启动。docker-compose.yml中的depen_on键不够
您还需要更新Dockerfile以利用docker compose wait
供参考-这是我更新的docker compose和Dockerfile文件

版本：“3.7”

我们的应用程序基于此，但没有使用
命令：mongod--smallfiles--logpath=/dev/null--quiet
我们使用
命令：mongod--smallfiles--bind_ip_all--logpath=/dev/null--quiet
。谢谢Patryk。进行了一次尝试，但仍然获得MongoError:在第一次连接时未能连接到服务器[mongodb:27027][MongoError:connect-Econrefuse172.18.0.2:27027]你是在使用docker compose up来运行一切吗？我们的应用程序基于此，而不是使用
