@ 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 ?
I m blessed that i have watched your videos!
All things are explained in good way.
All doubts are clear now.
This is an excellent video! It is worth watching every second if you are confused.
Glad it was helpful!
best explanation on YT

Thank you for your clear explanation.It help me to understand very easily.
Wonderfully explained
Super explanation sir
Well explained, thanks a lot
Nicely explained
Wow! nice explanation! Thank you very much.
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 .😊
Result is 1st line cmd instruction, and last line Entrypoint instruction is exicuted.
Excellent !! .Nicely explained this critical concept with example.
Many thanks!
Superbbb
Thanks for the recap

Thank you so much
Very simple
Very well Explained
Thanks !!
Glad it was helpful!
Thank you sir
thank you
top notch
First, the Git command will be installed. After that, the message "Hello world" will be echoed.
Thanks
Nice explanation but before that you would tell the executable and shellscript form
Can please do the vedio on docker COPY Vs ADD sir
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👍
Sir, I found this Output "Hello World yum -y install git" after running the above script in Dockerfile.
expected the same output
The output will be -
Hello World yum -y install git
Suppose we have entry point and also cmd in a sigle file.....which one executes first either cmd or entrpoint????
Always entrypoint will be the first
Output it will executed "Hello world"
Last one --> Hello Word
Latest entry point is executed first and later cmd git is installed
The last entry point argument will execute
Output: Hello World yum -y install git
The same output I got it, bro...
If possible can you explain?
cmd will install git and entry point will echo the content.
Output: Hello World
i think the answer should be "hello world" CMD will be ignored.
it install the git and helloworld excecuted
It will install Git and execute Last entrypoint Hello World
Hello world
Installing git
Firstly, it will install git and post that it will execute latest instruction -Hello world.
Hello world
hello world yum install -y git
hello Wolrd yum -y install git
Only Hello World in Last Entry point will execute
Hello World yum -y install git
can you explain?
please use: docker ps -a --no-trunc to see all the comments which are hidden in ...COMMAND Section
Output: Hello World yum -y install git
Hello world
