Calling the Python interpreter in docker with pychart

Reference article ：https://blog.csdn.net/ambm29/article/details/96483086#commentBox

utilize Pycharm Remote use Docker Medium Python The environment is divided into 4 Step ：

1. Ready to own Python Environmental Docker
2. to Docker install ssh-server And create a new image
3. Run the new image , Opening to the outside world ssh port
4. Pycharm Connect Docker The interpreter in

One 、 Ready to own Python Environmental Docker Mirror image

A little .

Two 、 to Docker Installation configuration ssh-server

Purpose ： In order to make Docker Can be ssh Command remote connection .

1. function Docker Image creates a new container , And install... In the container ssh-server

# Run the image to create a new container (python_env:3.2 It's made by yourself Python Environmental Docker)
sudo docker run -it --name python_env python_env:3.2
# It should already be in the container , install openssh-server
apt install update
apt install openssh-server -y
# start-up ssh service 
service ssh start # Output [ok] Starting OpenBSD Secure Shell server: sshd. That is success 
# see ssh Service status 
service ssh status

2. To configure ssh The login password , Here the password is set to “1237894560”, The user name defaults to “root”

# The terminal inputs the following commands 
passwd
# Enter new UNIX password: Input password 1237894560
# Retype new UNIX password： Enter the password again 1237894560
# passwd: password update successfully Password set successfully 

3. modify ssh Configuration file for

vim /etc/ssh/sshd_config

Modify the following two places

......
PermitRootLogin yes
......
UsePAM no
......

4. Create a folder for mounting items
   Purpose ： It can be omitted , Customize a directory for mounting items , After use

cd /home
mkdir PythonProject

5. Submit as a new image
   Here we are ,Docker In container ssh-server The configuration has been completed , Let's commit the container as a new image , Left for later use .

# Push out the container 
exit
# Look at all the containers in the system 
sudo docker ps -a
# Commit the container just now as a new image (python_env For the container name just now , You can also write containers ID)
sudo docker commit -a "lifan" -m "add ssh, passwd=1237894560" python_env python_env_ssh:1
# View the newly generated container 
sudo docker images

Be careful ： In the reference article , The author is in 1 Step installation openssh-server After the service ssh start It's set to ~/.bashrc In file , So as to achieve container startup ,ssh Self service .
But I'll use it later Pycharm Remote connected Docker I encountered the problem as shown in the figure below , I checked a lot of data and found that ~/.bashrc There is output information in the file .
So I won't start here ssh The command of wrote ~/.bashrc 了 .

3、 ... and 、 Run the new image , Mount items , Open ports

The reason why I did this , All because the leaders have to use Docker The environment in ,…, It's killing me .

1. Run the new image , Start a new container

sudo docker run -id --name python_env_ssh -p 7061:22 -p 5000:5000 -v /home/lifan/Python_SSH_Project:/home/Python_Project python_env_ssh:1

• -id： Container in interactive mode , Run in the background
• --name： Container name
• -p： Port number mapping , Host port ： Container port ,5000 It's for flask With ,7061 It's for ssh With
• -v： Directory mapping , Host project directory ： Container project directory

2. Because I'm up there , No settings ssh The self enlightenment of , So now you need to go into the container , Manual start ssh service ：

# Into the container 
sudo docker exec -it python_env_ssh /bin/bash
# start-up ssh service 
service ssh start

Four 、Pycharm Remote connection Docker

1. Add a new one Python Interpreter
   
2. choice ssh Remote connection interpreter , And configure
   
   If the connection is successful, go back to the following interface ;
   If not, check whether the container is started , In container ssh Whether the service starts ;
   
   

5、 ... and 、 Use the remote interpreter to run local programs

# -*- coding: utf8 -*-
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route("/", methods=["GET", "POST"])
def index():
return "Hello Flask"
if __name__ == '__main__':
print(app.url_map)
app.run(host="0.0.0.0", port=5000, debug=True)

Before running the project , You can see if the interpreter is correct

Enter the... Of the host in the browser IP, And then it's done .

Last , It's how to make ssh The service starts automatically when the container is started , Who has the time to leave a message and a blog link , thank .

The reference article is much more detailed than what I copied , You can read the original .
