Docker deployment Tomcat and Web application __docker

First, online download Docker

Yum install-y epel-release

yum install docker-io   # Install Docker chkconfig on     # join Boot

Service Docker start     # launch Docker service

Second, Docker install Tomcat container 2.1. Find the server's Tomcat information

2.2 Download down the official mirror starts the tallest one

Docker Pull  Docker.io/tomcat    

2.3 View all mirrors of Docker

Docker images     

2.4 Start Tomcat

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

2.5 access to 192.168.138.132:8080 after startup

third, deploy your own web references

Docker PS     # Use the following command to view a running container

3.1. Upload your own war package to the mainframe

3.2. Execute view address in container ComCat

Docker  exec-it   3cb492a27475   /bin/bash    

3.3 threw the war bag into the host , threw it into the container and dropped it into Tomcat/webapps.

Docker CP Nginxdemo.war 3cb492a27475:/usr/local/tomcat/webapps

3.4. Start Tomcat or reboot docker restart "container ID"

Docker Run-p 8081:8080 Docker.io/tomcat

3.5 View has started mirroring

Docker PS

3.6 Performing View items in the container comcat

Docker  exec-it   3cb492a27475   /bin/bash    #中间那个是容器id (container_id) 

Cd/webapps

ls   # You can find our project.

3.7 The above implementation has a disadvantage is that the container restart after the project will be no longer, the following is the mode of 2 boot in the form of Mount

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

3.8 The first two ways to use in the test environment, after all, to constantly modify the code, Mode 3 can be put into production use. is also the way the official website suggests

VI Dockerfile

From Docker.io/tomcat:latest    #你的 Tomcat mirroring
maintainer XXX@qq.com    #作者
COPY nginxdemo.war   /usr/ Local/tomcat/webapps  #放置到tomcat的webapps目录下

3.8.1 to generate a new mirror:

Docker build-t Nginx-demo:v1.  

3.8.2 start a new mirror

Docker Run-p 8080:8080 Nginx-demo:v1
