This article is about how Docker automatically deploys Apache Tomcat. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Use docker search to find the most popular (and official) Docker Tomcat containers:

Use docker pull to download the official image. Here I choose the official tomcat,latest version.

# docker pull tomcat

After the download is complete, use the docker images command to view the image

# docker imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEdocker.io/tomcat latest cb8603fe47ec 3 weeks ago 347.8 MB

Extending Dockerfile I need to extend Dockerfile to automate the deployment of Maven. You need to add settings.xml and update the tomcat-users.xml file. As follows:

Tomcat-users.xml:

Settings.xml:

TomcatServerchag111111

These files are placed in the same directory as Dockerfile.

The Dockerfile is updated to:

FROM tomcatMAINTAINER "CHAG" ADD settings.xml / usr/local/tomcat/conf/ADD tomcat-users.xml / usr/local/tomcat/conf/

When the image is built, the configuration file is placed in the correct directory. Any container launched from this image will contain these files.

Refactoring image: in the current file directory

# docker build-t chag/tomcat.

Start the container:

# docker run-d-name tomcat-p 8080 chag/tomcat

You can access the tomcat service using the IP:8080 of the host
