Download steps:

1) Problems encountered after installation:

2) Solutions:

3) Restart docker:

4) Verify docker

5) Try pulling a redis service image (command)

6) View the local desktop image:

7) Run a Redis container (not command)

8) View logs related to container operation:

9) Try using client connection:

10) Verify connection:

Can be used to add some mirror clouds:

"https://xxx.mirror.aliyuncs.com",
"https://registry.docker-cn.com",
"https://docker.mirrors.ustc.edu.cn",
"https://reg-mirror.qiniu.com",
"https://dockerhub.azk8s.cn",
"https://mirror.ccs.tencentyun.com"
Copy the code

After following the steps above, you can use Docker to install your own service! Feeling like you can really do anything you want! Ha ha! After installing what service, also convenient a lot! Don’t need so much configuration!!

3. Start configuring our PyCharm

PS: My PyCharm version is 18 drops

You might as well reboot it if you can

A Docker icon appears below

Pull up a mirror of the Python environment, and everyone else can build on that mirror and keep the environment consistent!

Pull up a mirror of the Python environment, and everyone else can build on that mirror and keep the environment consistent! Even if we run Python directly on Linux, we can create a Linux image to configure or install our Python environment.

For example, I can build a Linxu environment container to run our FastAPI project, so of course we need to build a mirror!

Start building a Linux + PY3 image:

Then wait for the build!

Error:

Modify, need to copy our file inside to install:

Added: COPY requirements.txt./

New content:

But the build process can still go wrong:

Tip:

Later, I simply stopped downloading it from Douban:

There is a new package that can not be installed

This package is so weird that no image can be installed:

Psycopg2 = = 2.9.1Copy the code

After removing the top one, it’s OK!

Then wait for the connection:

Looks like this place has been disconnected!! As it turns out, Docker also needs to download other images:

Image file big forget it! Still not connected!! Delete to generate a new image

Replace the new small mirror validation test

New image:

FROM Tiangolo/uvicoron-gunicoron-fastAPI :python3.7 # author label label Maintainer ="xiaozhong" COPY requirements.txt./ RUN pip3 install -r requirements.txt \ && yum clean all # expost port EXPOSE 15731Copy the code

And build it all over again!

Forget! Yum command has no place to go! It needs to be removed! After refactoring!

Start a container and try to test it to see the environment:

Tip:

Forget it again! This basic image is included to start our service now! We just need a Python environment now! This ！！！！ Embarrassed!

One more time!!

Then perform the build:

Run an example to verify the current Python environment:

Connect to our PyCharm again and try it out

This is weird. It’s always been:

It should be linked in a different way:

Connect again using the latest version 2021.2:

There are new tools for image generation:

Good guy finally can!! Confirm and wait for background process processing!!

Verify access: access failed ！！！！

Troubleshooting: (1) View container logs:

When we right-click to run our local project, the service launches the port number inside the container:

So we can get the information: http://127.0.0.1:8569/ this is the port number in the container, not our local, because our local has not mapped the port with the container 8569, so we cannot access the service drop!

The access address can be verified by our entry into the container:

(1) Modify the configuration information

(2) Find the container run configuration option

After adding man.py successfully, view the command in the receipt when finally starting man.py

(3) Make sure to change our launcher HOTS to 0.0.0.0 if you use 127.0.0.1 to only allow access from inside the container!! So no!

Accessing the interface again:

Congratulations you can!! Wow kaka.

Configure information about the running container (this is temporarily problematic, will be added later).

Conclusion:

The above is just a personal combination of their own actual needs, do study practice notes! If there are clerical errors! Welcome criticism and correction! Thank you!

At the end
