docker-compose

问题 In docker-compose I was used to create volumes in this way: volumes: - ./server:/home/app - /home/app/node_modules in order to solve the problem of node_modules . How could I approach the problem in kubernetes? I've created the following config spec: containers: - env: [] image: "image" volumeMounts: - mountPath: /home/app name: vol-app - mountPath: /home/app/node_modules name: vol-node-modules name: demo volumes: - name: vol-app hostPath: path: /Users/me/server - name: vol-node-modules

问题 docker-compose: mysql: image: mysql:5.7.16 container_name: f_mysql volumes: - ./db:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: sheep expose: - '3306' and I use docker exec input this container, and I type echo $MYSQL_ROOT_PASSWORD , then I got sheep , but the mysql root password still is '', when I type 'mysql -uroot', I login mysql. 回答1: You need to fix your docker-compose file: environment: - MYSQL_ROOT_PASSWORD=sheep The following is the full docker-compose that achieves what you want

问题 I have two containers, a apache-php container, and a mysql db container. I am trying to get my php script to query my sql database. I am however receiving the following errors; Fatal error: Uncaught PDOException: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known AND Fatal error: Uncaught PDOException: SQLSTATE[HY000] [2002] No such file or directory when toggling the host address, i think i am missing something fundamental to docker and this is

问题 Playing around with flask I would like to get a real setup up and running in docker. This means flask should be served via nginx and gunicorn. I set up a sample code repository https://github.com/geoHeil/pythonServing but so far can't get nginx to work properly. Flask is served on application:5000 , docker should resolve application to its respective name. Nginx config is as follows: server { listen 8080; server_name application; charset utf-8; location / { proxy_pass http://application:5000;

问题 My server has two network interfaces, eth0 and wlan0, one connected to the internet and the other to an internal network. The current solution of exposing Docker container ports with docker-compose to a specific interface is to use: version: '2' services: mosquitto: ports: - "192.168.0.1:1883:1883" This makes it brittle since the IP addresses are distributed via DHCP. Several devices are used, of which each may have a different IP address. Therefore, is it possible to expose ports to only a

问题 Container names, in docker-compose, are generated. And I need to pass this name to another container so it can make a connection. My scenario is, I want to create a container based on docker's container and communicating with the host, execute some thing in a sibling container as the second process within it. So how can I have a container's name within another? 回答1: That will be easy with docker-compose 1.6.1 and the addition of network-scoped alias in docker-compose issue 2829. --alias

问题 I have a docker-compose file with everything I need for my project. This docker-compose has a nginx server, mysql, phpmyadmin and php. At the top of it, I added recently an angular container. Everything is working fine if I go to localhost:4200, I'm on the angular app, and if I go to localhost:80, I'm on the Laravel backend. Now I need to make a simple classical request to my backend API. I set up a proxy for angular looking like this : { "/api/*": { "target":"http://localhost:80", "secure"

问题 I'm using docker compose to run my application. And for do that I need to set the hosts inside container (it's depends on the environment i'm running). My approach was: Create an environment file and set the variable: #application.env SERVER_IP=10.10.9.134 My docker compose file looks like: version: '2' services: api: container_name: myApplication env_file: - application.env build: ./myApplication/ entrypoint: ./docker/api-startup.sh ports: - "8080:8080" depends_on: - redis extra_hosts:
