Is it possible to mount folder from container to host machine?
As an example, I have a simple Node.js / Typescript application defined as follows:
FROM node:6.2 RUN npm install --global firstname.lastname@example.org COPY package.json /app/package.json WORKDIR /app RUN npm install COPY typings.json /app/typings.json RUN typings install
Node packages and typings are preinstalled to image.
typings folders are by default present only in running container.
node-app: ... volumes: - .:/app - /app/node_modules - /app/typings
I mount current folder from host to container, which creates volumes from existing folders from
/app. Those are mounted back to container so the application can work with them. The problem is that I’d like to see
typings folder on host system as a read-only folder (because some IDEs can show you type hints that can be found in this folder). From what I’ve tested, those folders (
typings) are created on host machine after I run the container, but they are always empty. Is it possible to somehow see their contents (read-only preferably) from container volumes only if the container is running?

You can’t make a host directory read-only from Compose. Compose orchestrates containers, not the host system.
If you want to share directories with the host, create them on the host first and mount them as bind volumes (like you’ve done with
