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

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

First, the Git command will be installed. After that, the message "Hello world" will be echoed.
Sir, I found this Output "Hello World yum -y install git" after running the above script in Dockerfile.
expected the same output
Nice explanation but before that you would tell the executable and shellscript form
Output it will executed "Hello world"
Output: Hello World yum -y install git
The same output I got it, bro...
If possible can you explain?
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
The output will be -
Hello World yum -y install git
Last one --> Hello Word
The last entry point argument will execute
cmd will install git and entry point will echo the content.
it install the git and helloworld excecuted
i think the answer should be "hello world" CMD will be ignored.
it install git by CMD and then print Hello World by ENTRYPOINT
It will install Git and execute Last entrypoint Hello World
hello Wolrd yum -y install git
Output: Hello World
hello world yum install -y git
Firstly, it will install git and post that it will execute latest instruction -Hello world.
Hello World yum -y install git
can you explain?
Only Hello World in Last Entry point will execute
Hello world
Installing git
Hello World yum -y install git
Hello world
please use: docker ps -a --no-trunc to see all the comments which are hidden in ...COMMAND Section
Well explained, thanks a lot
Output: Hello World yum -y install git
Hello world
