Deploying Java webapp to Tomcat 8 running in Docker container

java tomcat docker spring-boot war

You are trying to copy the war file to a directory below webapps. The war file should be copied into the webapps directory.

Remove the mkdir command, and copy the war file like this:

COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

Tomcat will extract the war if autodeploy is turned on.

java tomcat docker spring-boot war

There's a oneliner for this one.

You can simply run,

docker run -v /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war:/usr/local/tomcat/webapps/myapp.war -it -p 8080:8080 tomcat

This will copy the war file to webapps directory and get your app running in no time.

java tomcat docker spring-boot war

Tomcat will only extract the war which is copied to webapps directory. Change Dockerfile as below:

FROM tomcat:8.0.20-jre8COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

You might need to access the url as below unless you have specified the webroot
