Method of realizing automated deployment based on Docker+Jenkins

docker run -p 8080:8080 -p 50000:50000 -v jenkins_data:/var/jenkins_home jenkinsci/blueocean

docker exec -it 7f485bd95c3b /bin/bash enter the jenkins container cat /var/jenkins_home/secrets/initialAdminPassword 

clean install

# Source jar path, after mvn packaging is completed, the jar package name in the target directory can also be selected as a war package. The war package can be moved to the webapps directory of Tomcat for operation. Here, the jar package is used and the java -jar command is used to execute JAR_NAME=springboot-0.0.1-SNAPSHOT
# Source jar path #/usr/local/jenkins_home/workspace--->jenkins working directory #demo project directory #target package generated jar package directory JAR_PATH=/var/jenkins_home/workspace/springboot/target
