docker-compose

问题 I'm dockerizing a web application that uses Django Channels for websocket functionality. It depends on redis. I'm having trouble getting the redis portion of the application to work correctly. I've tried to stick to this redis/compose guide. docker-compose.yml version: "3" services: db: image: mysql:latest volumes: - "./.mysql-data/db:/var/lib/mysql" restart: always ports: - 3306:3306 environment: MYSQL_ROOT_PASSWORD: rootpassword MYSQL_DATABASE: database MYSQL_USER: user MYSQL_PASSWORD:

问题 Let's use this docker-compose.yml : version: '2' services: db: image: mysql:5.7 volumes: - ./mysql:/var/lib/mysql # <- important restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest volumes: - ./wp:/var/www/html # <- important ports: - "8000:80" restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD:

问题 At the moment I have two containers which I build from an image and then link the two: For example: #mysql docker build -t my/mysql docker-mysql docker run -p 3306:3306 --name mysql -d my/mysql:latest #webapp docker build -t my/tomcat:7.0 tomcat/7.0 docker run -d --link mysql --name tomcat7 my/tomcat:7.0 Since I'm linking the webapp container with mysql container, the webapp container gets a MYSQL_PORT_3306_TCP_ADDR environment variable created. I use this environment variable to then connect

问题 I am trying to run docker-compose with two .net core console applications having dependency of rabbitMQ, I am using Docker with Windows. I have added to console application, as described on RabbitMQ official docs https://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html Outside of both applications I have added docker-compose.yml Folder structure: 1. Send Send.cs (as it is in RabbitMQ docs) Send.csproj Dockerfile FROM mcr.microsoft.com/dotnet/core/sdk:2.2 as build-env WORKDIR /app # Copy
