How to install tomcat8 in docker

1. Install tomcat8 with docker

1. Find the tomcat image on Docker Hub

docker search tomcat

2. Pull the tomcat image

docker pull tomcat:8

3. Use the default configuration of Tomcat to start a Tomcat container

docker run -d -p 8080:8080 --name tomcat tomcat:8

4. Copy the tomcat configuration files and logs in the container to the local machine for mapping

docker cp tomcat:/usr/local/tomcat/conf /usr/app/tomcat/conf

docker cp tomcat:/usr/local/tomcat/logs /usr/app/tomcat/logs

5. Stop tomcat and delete the container

docker stop tomcat
docker rm tomcat

6. Create and run the tomcat container

docker run -d -p 8080:8080 --name tomcat -v /usr/app/tomcat/webapps:/usr/local/tomcat/webapps -v /usr/app/tomcat/conf:/usr/local/tomcat/conf -v /usr/app/tomcat/logs:/usr/local/tomcat/logs --restart=always tomcat:8

7. View the created container

docker ps | grep tomcat

Notice

When the Tomcat version is too high, the following problems may occur when accessing based on the IP address and port number:

The 404 error occurs because the content in the webapps folder is empty. The content is in the webapps.dist directory. The solution is as follows:

1. Enter the tomcat container

docker exec -it container id /bin/bash

2. Use ls to view the folder contents. You can find that there are webapps folder and webapps.dist folder. Move all the contents under webapps.dist to webapps.

mv webapps.dist/* webapps

3. Revisit tomcat.

Remember to allow security groups and firewalls.
