and checked directory to /usr/local/tomcat but there is no the directory, where is the tomcat directory ?

Answer 1

According to official Tomcat image documentation (On DockerHub), Tomcat location is indeed /usr/local/tomcat.

I've executed docker run -it --rm -p 8080:8080 tomcat:8.0 /bin/bash and I can confirm this is true. Please try executing the above command and check the results.

FYI, adding /bin/bash at the end of the docker-run command will execute BASH inside the container and let you interact with its contents.
