我有一个具有以下结构的项目。
ProjectName/
├── Dockerfile
├── api/
│ ├── Dockerfile
│ └── manage.py
├── docker-compose.yml
├── frontend/
│ ├── Dockerfile
│ ├── build/
│ └── src/
└── manifests/
├── development.yml
└── production.yml
docker-compose.yml有一个在两个环境之间都很常见的数据库映像,而dev.yml和prod.yml对于生产和dev有相似但略有不同的映像。
示例:api dev使用django并且只运行python manage.py runserver
,但是在prod中它将运行gunicorn api.wsgi
。
并且前端运行npm start
但是在生产中我希望它基于不同的图像。目前,dockerfile仅适用于其中一个,因为npm
命令仅在我使用FROM node
时找到,而nginx
命令仅在我使用FROM kyma/docker-nginx
时显示。
那么在不同的环境中如何将它们分开呢?
./ frontend / Dockerfile:
FROM node
WORKDIR /app/frontend
COPY package.json /app/frontend
RUN npm install
EXPOSE 3000
CMD ["npm", "start"]
# Only run this bit in production environment, and not anything above this line.
#FROM kyma/docker-nginx
#COPY build/ /var/www
#CMD 'nginx'
./ API / Dockerfile:
FROM python:3.5
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
postgresql-client \

WORKDIR /app/api
COPY requirements.txt /app/api
RUN pip install -r requirements.txt
EXPOSE 8000
# Run this command in dev

# Run this command in prod

根据您可以在运行时设置的环境变量,您可以使用运行一个或另一个命令的脚本作为ENTRYPOINT:
docker run -e env=DEV
# or
docker run -e env=PROD
