How do I mount a host directory as a volume in docker compose
docker, docker-compose, docker-volume
Solution
Checkout their documentation
From the looks of it you could do the following on your docker-compose.yml
volumes:
- ./:/app
Where `./` is the host directory, and `/app` is the target directory for the containers.
EDIT: Previous documentation source now leads to version history, you'll have to select the version of compose you're using and look for the reference.
For the lazy – v3 / v2 / v1
Side note: Syntax remains the same for all versions as of this edit
Problem
I have a development environment I'm dockerizing and I would like the ability to livereload my changes without having to rebuild docker images. I'm using docker compose because redis is one of my app's dependencies and I like being able to link a redis container I have two containers defined in my `docker-compose.yml`: ``` node: build: ./node links: - redis ports: - "8080" env_file: - node-app.env redis: image: redis ports: - "6379" ``` I've gotten to the point in my `node` app's dockerfile where I add a volume, but how do I mount the the host's directory in the volume so that all my live edits to the code are reflected in the container? Here's my current Dockerfile: ``` # Set the base image to Ubuntu FROM node:boron # File Author / Maintainer MAINTAINER Amin Shah Gilani <amin@gilani.me> # Install nodemon RUN npm install -g nodemon # Add a /app volume VOLUME ["/app"] # TODO: link the current . to /app # Define working directory WORKDIR /app # Run npm install RUN npm install # Expose port EXPOSE 8080 # Run app using nodemon CMD ["nodemon", "/app/app.js"] ``` My project looks like this: ``` / - docker-compose.yml - node-app.env - node/ - app.js - Dockerfile.js ```
