Hello sir the way you explained ...you really nailed it! Hats off to you !!!!you are really a gem of Devops ...Thankyou so much I wish if you could make videos on docker compose and docker swarm too.
Superb tutorial. Complex topic explained very systematically and succintly. Liked the split screen technique of comparing the route map for image build with actual real world implementation of building the docker image.👍

It shows error "ERROR: Build step failed with exception" i had given the tomcat-users.xml correctly. But still it is showing the error. Could you please help me with this...
If you, for one reason or the other, are still actively using CentOS 8, you might probably have encountered the following error when trying to update your system or simply install a package. “Error: Failed to download metadata for repo ‘appstream’: Cannot prepare internal mirrorlist: No URLs in mirrorlist” You may well be aware that CentOS Linux 8 died a premature death, it reached the End Of Life (EOL) on December 31st, 2021, thus it no longer receives development resources from the official CentOS project.
Sooper explained. No one till now explained this way.
Many Thanks !

Thank you for upload a video nice explanation ....pls upload docker compose and docker swarm sir
We can able to do on docker compose, But we preferred to discuss Kubernetes rather than docker swarm.
what is the difference between docker build and docker run?
Build is to create image from Dockerfile and run is to create a container
Yes. thats true.
Need a special video on CMD And Entry point
Working on it
