For example, you can run the following command: docker run -v path/to/your/file/on/host:path/to/the/file/on/container your_image The only approach to access the host file is that you can mount the

阅读更多关于 Accessing node_modules after npm install inside Docker

问题 I am running Docker with Docker Machine on Mac. I successfully set up some containers and ran npm install inside them, as explained here. This installs the node_modules inside the image and inside the container, but they are not available on the host, i.e. my IDE complains about missing node_modules. Am I missing something? What is the best way to run npm install inside the container but be able to do development (with these dependencies) on the host? From my docker-compose.yml: volumes: -

阅读更多关于 How do I enable the Docker RestAPI on Windows Containers?

I used this official guide to install Docker Containers on Windows. Everything looks good and I can run IIS on Windows Containers now.
