docker-volume

问题 I'm newbie in Docker and I have created an image with this Dockerfile: FROM node:8.12.0 LABEL version="1.0" WORKDIR /usr/src/app COPY package*.json ./ RUN npm install COPY . . EXPOSE 8080 CMD ["node", "index.js"] I run the image and it works. But If I run the image mapping host directory with WORKDIR when I update index.js in host directory this updating is not propagated into WORKDIR. I run the image with this command: docker run --name basketmetrics -v /home/josecarlos/Workspace/nodejs

问题 I'm just trying out WSL 2 with Docker for Windows and I'm having an issues with mounted volumes : version: "3.7" services: node: build: . container_name: node hostname: node volumes: - ./app:/app stdin_open: true the container build and start well, I access it with docker exec nicely but the /app folder inside the container isn't bound to my laptop app folder. However the right path is actually correctly mounted on the running container : (here I do pwd on the host to if it matches perfectly

问题 I've seen Docker volume definitions in docker-compose.yml files like so: -v /path/on/host/modules:/var/www/html/modules I noticed that Drupal's official image, their docker-compose.yml file is using anonymous volumes. Notice the comments: volumes: - /var/www/html/modules - /var/www/html/profiles - /var/www/html/themes # this takes advantage of the feature in Docker that a new anonymous # volume (which is what we're creating here) will be initialized with the # existing content of the image at

问题 When I do a docker volume inspect <dockerid> on a Mac, I can see the path to the data, this appears as a /var/lib/docker/volumes/<volume name> On a Mac, this link does not exist, because docker runs on inside a very tiny VM. I can use screen ~/Library/Containers/com.docker.docker/Data/vms/0/tty to get into the vm and then navigate to the folder to see the volumes. So got all that, but my question is: How do I link what is in these volumes on my host machine? I have tried this: docker run -it
