After clicking the "OK" button, select "Source Code Management" and select "Git" to set the "Repository URL" address.
Select "Build" -> clean package -Dmaven.test.skip=true
Select the "Send build artfacts over SSH" option in "Post-Build Actions" after the previous step and proceed.
scp 192.168.200.112:/root/.jenkins/workspace/probe-docker/psi-probe-web/target/probe.war /data/
docker run -itd --name tomcat-test -p 8090:8080 -v /data:/usr/local/apache-tomcat-8.5.40/webapps tomcat:v1
After all the above configurations are completed, click Save. Then click "probe-docker"->"Build new" on the engineering task you just created until the task is built. You can click on the progress bar to view the build process.
You can see that this engineering task has been built successfully, and after the build, the command to create a Docker Web environment for the docker project has also been executed successfully.
