This article will explain in detail how to use Docker to build a Django,Nginx,R,Python deployment environment. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Basic environment:

Ubuntu 16.10

Docker 17.06.0-ce

Compress your own project files

1. It should be noted here that when compressing, you also need to write your own Python package in requirement.txt, so that when you build the environment, you will know what package you need to install together. The requirement.txt content of my project is as follows.

?

one

two

three

four

five

six

seven

eight

Django==1.10.5

Rpy2==2.8.5

PyMySQL==0.7.9

Numpy==1.13.0

Pandas==0.20.2

Scikit-learn==0.18.1

Scipy==0.19.0

Uwsgi

two。 Change your settings.py to set up the deployment environment for the Nginx server agent

The changes are as follows

?

one

two

STATIC_ROOT = os.path.join (BASE_DIR, 'collect_static')

ALLOWED_HOST = ['*']

Note: the deployed environment cannot be the same as the static file of the development environment, otherwise it will cause an error.

After modification, run the following command:

one

Python manage.py collectstatic

At this time, you can compress the file with peace of mind.

one

Tar czvf FileName.tar DirName

Build web environment

1. Put the packaged project files in the web folder

one

Cp / home/haoyu/AAPlatform.tar.

two。 Write Dockerfile

Here is mainly to build the basic environment.

Basically, the environment built by Django and R is here.

two。 Write start.sh

Here is to run the Django of docker

The contents are as follows:

#! / bin/bash

#

Docker build-t aaplatform/django-app.

Docker run-- name django\

-v / usr/src/AAPlatform/collect_static\

-p 12000VOG 8000\

-d feiyu/django-app / usr/local/bin/uwsgi-http: 8000-chdir / usr/src/AAPlatform-w AAPlatform.wsgi

#-d aaplatform/django-app / usr/local/bin/gunicorn myblog.wsgi:application-w 1-b: 8000

Build Nginx environment

1. Write Dockerfile files

Configure the Nginx-related environment

FROM daocloud.io/nginx

MAINTAINER haoyu

RUN rm / etc/nginx/conf.d/default.conf

ADD nginx-conf/ / etc/nginx/conf.d/

two。 Write Server configuration file

The default configuration file of the system needs to be changed

In nginx-conf:

Server_name localhost

Charset utf-8

Root / usr/src/AAPlatform

Access_log / var/log/nginx/django.log

Location ^ ~ / static {

Alias / usr/src/AAPlatform/collect_static

}

Location / {

Proxy_pass http://web:8000;

Proxy_set_header Host $host

Proxy_set_header X-Real-IP $remote_addr

Proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

}

}

Ensure that the Nginx environment can be built.

3. Write start.sh

Get docker up and running

#! / bin/bash

#

Docker build-t nginx.

Docker run-- name nginx-server\

-- link django:web\

-v / www/collect_static\

-- volumes-from django\

-p 8888purl 80\

-d nginx

The combination of the whole environment

1. Build docker-start.sh

Start web and Nginx

Cd. / web

Echo "start web -"

. / start.sh

two。 Write stop.sh

Close docker

three

four

five

# / bin/bash

#

Sudo docker kill $(docker ps-a-Q)

Sudo docker rm $(docker ps-a-Q)

Run the test

1. Run the sh file

one

$. / docker-start.sh

two。 Visit the website

Http://127.0.0.1:8888/login

Note: you are accessing the Nginx server.

Export the deployed image file

one

Docker save 00273588addb-o aaplatform.tar aaplatform/django-app:latest

2.docker load

one

Docker load < aaplatform.tar
