docker-compose

问题 I'm trying to switch my local Pycharm + Django to docker based dev env. I run on mac and use Docker-Compose (few dockers: my django app, some db and nginx). All runs fine, code change immediately reflected in docker and correct packages available while coding in Pycharm. Once docker-compose started, a list of running containers is shown in Pycharm's docker plugin window, for each container i can see its log/properties/port/volume bindings. Interpreter seems to be configured properly with

问题 I would like to use scale but I need different volumes and port mapping for each node. How can I do that? Ideally I would need some kind of environment variable or a script that is run to allocate a volume and ports for each new instance. What is the recommended way to do this? 回答1: I am aware that this might not be a perfect solution but if you don't mind sharing data between nodes.. it does work well. I am using this for local tests so it is safe in my case. Docker-compose.yml ... volumes:

问题 TL;DR : How can I pass env variable when building the image with docker-compose and have docker run image command recognize them ? I have this Dockerfile : FROM mhart/alpine-node:10 ADD . /app WORKDIR /app RUN apk --no-cache add --virtual builds-deps build-base python &&\ yarn global add nodemon &&\ yarn &&\ apk del builds-deps build-base python and this docker-compose.yml : version: "3.3" services: api: build: context: . dockerfile: Dockerfile-preprod image: registry.git.louis-girones.fr

问题 I have a docker-compose.yml file that starts up a simple HTTP echo service on port 8800 . version: '2' services: echo-server: image: luisbebop/echo-server container_name: echo-server ports: - "8800:8800" Super simple stuff. If I run docker-compose up and run on my local machine: echo "Hello World" | nc 127.0.0.1 8800 Then I see the echo. However: If I run this same compose scenario inside a docker container, through the GitLab runner, it fails. I've tried to garner attention for this issue at

问题 Having the following docker-compose file: db: build: . environment: - MYSQL_ROOT_PASSWORD=password - ENV=test env_file: .env Is there any way to use the env variables declared in docker-compose.yml (either as environment or declared in the env_file) as part of Dockerfile without declaring them in the Dockerfile?
