如何使用docker-compose在Openshift Container平台中部署？

Question

我不熟悉Openshift Container Platform。我正在尝试部署使用node、redis和mongo的应用程序。我已经编写了Dockerfile和docker-compose.yml。我能够在本地系统中成功运行它。我面临的挑战是在Openshift中部署。下面是我的Dockerfile和docker-compose.yml：

Dockerfile：

# Install node v10
FROM node:10.16.3

RUN apt update && apt install -y openjdk-8-jdk

# Set the workdir /var/www/myapp
WORKDIR /var/www/myapp

# Copy the package.json to workdir
COPY package.json .

# Run npm install - install the npm dependencies
RUN npm install

# Copy application source
COPY . .

# Copy .env.docker to workdir/.env - use the docker env
#COPY .env.docker ./.env

# Expose application ports - (4300 - for API and 4301 - for front end)
# EXPOSE 4300 4301
EXPOSE 52000

CMD node app.js

docker-compose.yml：

version: '3'
services:
  myapp:
    container_name: myapp
    restart: always
    build: .
    ports:
      - '52000:52000'
      # - '8080:8080'
    #   - '4300:4300'
    #   - '4301:4301'
    links:
      - redis
      - mongo
  mongo:
    container_name: myapp-mongo
    image: 'mongo:4'
    ports:
      - '28107:28107'
      # - '27017:27017'
  redis:
    container_name: myapp-redis
    image: 'redis:4.0.11'
    ports:
      - '6379:6379'

Answer 1

您可以使用kompose (https://kubernetes.io/docs/tasks/configure-pod-container/translate-compose-kubernetes/)将docker-compose资源转换为k8s清单。我不认为你可以在不使用其他工具的情况下直接部署组合文件。

Answer 2

您可以使用Docker Swarm。如果你对docker-compose比较熟悉，看看它可能对你有帮助(https://docs.docker.com/engine/swarm/stack-deploy/)。
