在Docker容器中开发Node.js应用程序
我试图将本地开发环境设置为所有Node.js应用程序都在docker容器中开发。我们的团队在Linux、macOS和Windows上工作，因此这将有助于我们限制由此产生的一些问题 我们在节点框架中使用Sails.js，我不确定问题是在Docker设置中，还是与Sails本身有关 下面是我的在Docker容器中开发Node.js应用程序,node.js,mongodb,docker,sails.js,Node.js,Mongodb,Docker,Sails.js,我试图将本地开发环境设置为所有Node.js应用程序都在docker容器中开发。我们的团队在Linux、macOS和Windows上工作，因此这将有助于我们限制由此产生的一些问题 我们在节点框架中使用Sails.js，我不确定问题是在Docker设置中，还是与Sails本身有关 下面是我的docker run命令，它几乎可以工作： docker run --rm -it -p 3000:3000 --name my-app-dev -v $PWD:/home/app -w /home/app -

2019-09-05 15:58:38.800 | error | error: Could not tear down the ORM hook. Error details: Error: Consistency violation: Attempting to tear down a datastore (`myMongoTable`) which is not currently registered with this adapter. This is usually due to a race condition in userland code (e.g. attempting to tear down the same ORM instance more than once), or it could be due to a bug in this adapter.

第一个问题似乎与Sails.js及其sailsmongo
ORM适配器有关。第二个问题似乎是连接数据库的问题。因此，我不确定第一个问题是否是一个转移视线的问题，其根本问题是缺少数据库连接
如果有人对如何在Docker容器中运行Sails.js应用程序有任何建议，可以访问机器的localhost
和MongoDB，我希望得到一些帮助 除了在docker run
命令中的--network host
之外，还需要在连接属性中定义主机的IP，而不是localhost
，因为容器中的localhost指的是容器本身。如果要使代码中的连接属性保持一致，可以让每个开发人员在/etc/hosts
中设置一个环回别名，例如127.0.0.1 my.host.com
，并将连接属性设置为该主机名（“my.host.com”），例如MongoDB的my.host.com:27017
默认情况下，Docker创建网桥网络，并为任何连接的容器和主机操作系统分配IP地址。运行ifconfig并搜索docker0接口将显示Docker用于网络的IP地址范围
这通常非常有用，因为它将任何正在运行的Docker容器与本地网络隔离，确保只有显式打开到本地网络的端口才会公开，从而避免任何潜在冲突
但有时，Docker容器可能需要访问主机的服务
实现这一目标有两种选择：
使用以下代码从容器中获取主机IP地址：
#从Docker容器中获取主机的IP
通过运行以下命令，可以将Docker容器连接到本地网络：
docker运行--network=“host”
如果您使用docker compose，则可以添加一个以主机作为驱动程序的网络
这将把容器连接到主机网络，从而允许Docker容器通过localhost访问主机上运行的任何服务。它也适用于在本地网络上运行的任何其他Docker容器，或其端口暴露于本地主机的任何其他Docker容器。我已经尝试了这两个步骤，但无论发生什么，都会得到相同的结果。无法连接到Mongo。是否尝试使用端口公开Mongo并通过此端口访问？
