01

-

Docker CentOS Image

Find the CentOS version in Docker Hub, find the official CentOS image, and download centos7

Let it download first, we use the host to download JDK.

Log in to Oracle and choose JDK 11 to download (choose the version you use, which I have never used before. Try it!), get the directory of the host after the download is complete. My current absolute path is

D:\ jdk-11.0.4_linux-x64_bin.tar.gz

02

-

Start the container

Docker run-d-I-t / bin/bash

So we created a docker container

Copy JDK to the container

The JDK you just downloaded needs to be copied into the container for installation.

Docker cp D:\ jdk-11.0.4_linux-x64_bin.tar.gz 009afb75760f:/

Next we execute docker exec-it 009afb75760f / bin/bash to enter the container

Currently, execute ls in the root directory to see the jdk package under the current path, and execute the decompression command.

Set environment variabl

Vim / etc/profile (install vim yourself and get used to using vim)

Set up JAVA_HOME

Set up PATH

Save, exit

Source / etc/profile makes the configuration effective, and then executes java-version to check the installation version information. If you return successfully, the installation is successful.
