Difference between CMD and Entrypoint | CMD an Entrypoint differences with examples

[@artipathak670]

I m blessed that i have watched your videos! All things are explained in good way. All doubts are clear now.

[@KrishnaRac]

@ 20:24 in dockerfile you have defined multiple entrypoint, instruction, which is not allowed. docker only allows one entrypoint instruction in a dockerfile. So when you have multiple entrypoint instructions only the last one will be used. It will execute only "Hello World" and previos cmd and entrypoint will be ignored am i right ?

[@kirtimalviya6162]

No, entrypoints can be used multiple times in the docker file, but CMD instruction can only be used once.

[@soumyadipchatterjee2267]

Struggling to understand the cmd and entrypoint , now its clear and crystal to me . Your last question answer will be it prints echo Hello World as the Entry point always replace all of the commands in CMD ,so here in Docker ps it's just create echo Hello-world container .😊

Can please do the vedio on docker COPY Vs ADD sir

[@AlwaysOnHeaven]

it's simple CMD command can copy the file but can't download the from url so that's why we use ADD command to download any file from url and copy it to specific directory👍
