With the continuous promotion of modern product research and development , We will find that , Almost every product line will contain services with different functions , Moreover, there will be complex dependence and dependency relationship between services , This brings about a worldwide problem , When the project is deployed, the operation and maintenance department needs to manually configure the protocol and address of communication between services , A little carelessness will lead to abnormal service , At the same time, if the server changes the physical machine due to bad channel or other reasons , The cost of relocating a new environment can also be very high . therefore , We will place our hopes on Docker This container technology allows us to quickly and quickly deploy all the services we need to build our products , And you can scale horizontally according to your needs , And it can ensure stable disaster tolerance , In case of problems, you can use the daemons to automatically restart or start disaster recovery backup .

This time we will be in Win10 Use... In the environment Docker Container technology for front and rear separation projects Django+Vue.js package , Customize the corresponding project image separately , Respond to the requirements of rapid deployment and high expansion .

First of all, of course, installation Docker, You can refer to this video introduction :win10 Installation configuration Docker And change domestic sources .

Then install it on the host gunicorn, In the container, we start it asynchronously Django

pip3 isntall gunicorn gevent

Django Project configuration settings.py Corresponding application :

# Application definition
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'corsheaders',
'rest_framework',
'myapp',
'dwebsocket',
'gunicorn'
]

And then in Django The root directory of the project gunicorn Configuration file for :gunicorn.conf.py

import multiprocessing
bind = "0.0.0.0:8000" # The binding of ip And port
workers = 1 # Number of processes 

Pay attention here ,ip Must be 0.0.0.0, Don't write as 127.0.0.1, Otherwise, the external environment will not be able to access the services in the container , Next, write the dependency list in the root of the project :requirements.txt

Django==2.0.4
django-cors-headers==2.5.3
djangorestframework==3.9.3
celery==4.4.2
dwebsocket==0.5.12
redis==3.3.11
pymongo==3.8.0
PyMySQL
Pillow
pyjwt
pycryptodome
selenium
qiniu
gunicorn
gevent

What needs to be noted here is , Some dependent libraries are best used == Mark out the small version , Because it will pass through the container later pip During installation , The system may automatically help you install the latest version, resulting in some dependency errors .

Here's the old routine , Write in the root directory DockerFile file :

FROM python:3.7
WORKDIR /Project/mydjango
COPY requirements.txt ./
RUN pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
COPY . .
ENV LANG C.UTF-8
CMD ["gunicorn", "mydjango.wsgi:application","-c","./gunicorn.conf.py"]

The basic image of this time we choose 3.7, After all 2020 Years. , It is necessary to keep pace with the times .

ok, everything , Run the command to package the project :

liuyue@DESKTOP-NVU6CCV MINGW32 ~/www/mydjango (master)
$ docker build -t 'mydjango' .

SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

One point to note here is to enter the project directory to execute

docker build -t 'mydjango' .

My project directory here is mydjango.

The first time you package and compile , Maybe a little longer , Just be patient for a while , If you encounter a failure caused by a network error , Execute the packing command repeatedly , Now run the command :

docker images

You can see that the compiled image probably has 1g about :

liuyue@DESKTOP-NVU6CCV MINGW32 ~
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mydjango latest c3ffb74ae263 24 hours ago 1.04GB

Then start the mirror service :

docker run -it --rm -p 5000:8000 mydjango

Here we use port mapping technology to convert the host's 5000 Ports are mapped to... In the container 8000 port , visit Django service ,http:// Containers ip:5000

The back end is done , Next, it's our front-end service vue.js 了 , Start by opening vue Package configuration file for the project config/index.js:

build: {
// Template for index.html
index: path.resolve(__dirname, '../dist/index.html'),
// Paths
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
assetsPublicPath: './',
/**
* Source Maps
*/
productionSourceMap: true,
// https://webpack.js.org/configuration/devtool/#production
devtool: '#source-map',
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
}
}

Change the packing directory to a relative path , At the same time, pay attention to the routing configuration , If it was ever changed to history Remember to change the mode back to hash:

export default new Router({
routes:routes,
//mode:'history' /*hash*/
})

The preparations are complete , stay vue Under the project root directory Dockerfile:

FROM node:lts-alpine
# install simple http server for serving static content
RUN npm install -g http-server
# make the 'app' folder the current working directory
WORKDIR /app
# copy both 'package.json' and 'package-lock.json' (if available)
COPY package*.json ./
# install project dependencies
RUN npm install
# copy project files and folders to the current working directory (i.e. 'app' folder)
COPY . .
# build app for production with minification
RUN npm run build
EXPOSE 8080
CMD [ "http-server", "dist" ]

Here we choose smaller alpine Mirror image .

Then go to the root of the project , Execute package command :

docker build -t myvue .

My front-end directory here is myvue

liuyue@DESKTOP-NVU6CCV MINGW32 ~/www/myvue (master)
$ docker build -t myvue .
Sending build context to Docker daemon 202.1MB

SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

The system will automatically install the dependency according to the script , It takes a while for the first time .

After packing , perform :

docker images

You can see that the volume of the front-end mirror is smaller :

liuyue@DESKTOP-NVU6CCV MINGW32 ~
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
myvue latest 917d1c69f10f 23 hours ago 539MB

Run front end services :

docker run -it --rm -p 8081:8080 myvue

Also use port mapping , This time the host uses 8081, Yes, of course , If necessary, you can modify it according to your preference .

visit Vue.js service ,http:// Containers ip:8081

thus , adopt Docker Container technology , We have deployed the front and rear end services separately , The process is not complicated , But the significance is a milestone , With these two mirror images , Pull left Django, Right engine Vue.js, If you need lateral expansion one day , Just a few minutes , We can do it on the new server “ The bag in ”, Flexible and convenient . Finally, we present the project documents , Let me share with you :https://gitee.com/QiHanXiBei/... https://gitee.com/QiHanXiBei/myvue
