yum install -y epel-release

yum install docker-io # Install docker

chkconfig docker on # Add service to boot docker start # Start docker service

# docker search tomcat 

docker pull docker.io/tomcat

docker images 

docker run -p 8081:8080 docker.io/tomcat # If the port is occupied, you can specify the mapping port of the container and the host. The former is the external access port: the latter is the internal port of the container 

docker ps # Use the following command to view the running container 

docker exec -it 3cb492a27475 /bin/bash #The one in the middle is the container ID (CONTAINER_ID) 

docker cp NginxDemo.war 3cb492a27475 :/usr/local/tomcat/webapps

docker run -p 8081:8080 docker.io/tomcat

docker ps 

docker exec -it 3cb492a27475 /bin/bash #The one in the middle is the container ID (CONTAINER_ID) 

cd /webapps

ls # You can view our project

docker run -d -v /usr/docker_file/NginxDemo.war:/usr/local/tomcat/webapps/NginxDemo.war -p 8080:8080 docker.io/tomcat

from docker.io/tomcat:latest #your tomcat image MAINTAINER [email protected] #author COPY NginxDemo.war /usr/local/tomcat/webapps #Place it in the webapps directory of tomcat 

docker build -t nginx-demo:v1 . 

docker run -p 8080:8080 nginx-demo:v1
