问题 When building my Spring-boot image using Maven I now do this inside the Dockerfile. Maven will download all dependencies and then compile my files. This takes quite some time. How can I specify that the build process via docker-compose (Dockerfile) re-uses my "Windows10 Home" Maven repository? So, the number of (new) downloads is minimal. My dev context: I use the Docker quickstart terminal, so using a docker-machine. The is is a part of my docker-compose.yml file: version: '3' services:

问题 I am experimenting with the new docker networking feature. I migrated my old setup using container links to the new bridge network; so far, I have my dedicated bridge network up and running among multiple containers on the same host. Now I am looking for a means to replicate multiple link aliases for the same container. Say, I have a container named myBox that joins the docker network. I want to have the same container also reachable as myServer . Using links, I would simply set up two links

问题 My docker-compose have a two service, and docker-compose.yml define enviroment variable ip address with container name, version: '2' services: api: build: ./api/ command: python3 manage.py runserver volumes: - ./api:/code ports: - "8000:80" networks: - dock_net container_name: con_api web: build: ./web/ command: python3 manage.py runserver volumes: - ./web:/code ports: - "8001:80" networks: - dock_net container_name: con_web environment: Ip:con_ip networks: dock_net: driver: bridge But

问题 I'm using docker-compose for a Rails setup. To sync the files, I've mounted the directory like (some of the code is omitted): app: build: . command: rails server -p 3000 -b '0.0.0.0' volumes: - .:/app However, when running the app, I don't want the folder, tmp, to be synced. Adding the folder to dockerignore only solves the problem when building the docker image. How can I ignore the tmp folder from being synced between the host and guest when running docker compose? 回答1: You can add a second

问题 I try to build a docker-based development box for our django app. It's running smoothly. None of my teammembers will care about that until there is a nice IDE integration, therefore I play the new and shiny Docker Support in pycharm 5. I followed the linked documentation and pycharm does recognise my web container and it's python interpreter. Here's my docker-compose.yml: web: build: . ports: - "8000:8000" volumes: - .:/srv/app links: - database - search - cache entrypoint: /home/deployer/web

问题 I'm just learning docker and all of its goodness like swarm and compose. My intention is to create a Redis cluster in docker swarm.
