I have gone through Udemy courses, there instructor focuses on their task such as CI/CD but here videos are for free and very well explained. Anyone can understand easily and practice for same. I learnt Jenkins, GIT, Docker from your videos.

Thanks a lot for these awesome playlists.

Beautifully explained to start with docker compose. Suggestion: Every time you use DOCKER PS, please show us output of DOCKER PS -A as well (curious to see if containers are dead on DOCKER-COMPOSE DOWN command). Please keep posting more and more videos. Thanks a lot. Cheers!

Very concise and crisp explanation. What I liked most is, describing in just required detail, and the explaining the alternative ways in a very smart and quick way.
