Docker install Tomcat
Method 1. Build through Dockerfile
Create Dockerfile
First, create the directory tomcat to store later related things.
php@php:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
The webapps directory will be mapped to the application directory configured by the tomcat container
The logs directory will be mapped to the log directory of the tomcat container
The configuration file in the conf directory will be mapped to The configuration file of the tomcat container
Enter the created tomcat directory and create a Dockerfile
