Hi Mr Kiwenlau,

the following are my question I would like ask :

1. I'm confuse on what are the file inside the docker image before get get clone from the GitHub ?
2. how you build your kiwenlau/hadoop-master in docker hub ? I very curious to learn that !
   Would you mind teach me how you build those ?

3 Hope to heard from you soon ! 👍 Thanks ! 👍

Sorry for the late reply.

1. I can not understand the first problem.
2. Build image using "docker build" command and push image to DockerHub using "docker push" command:

You can check following file for building all docker images:

Hi Mr Kiwenlau,

1. What I am trying to ask is, Do you mind indicate a step by step guide on how you create the
   docker images ? At least i have a draft idea on how you create your docker images file maybe 1
   example? 👍
2. Why do we need clone the source code from GitHub? Cant we just develop 'the source code directly
   from dockerfile? 👍
3. How to see what is inside the "sudo docker pull kiwenlau/hadoop-master:0.1.0." before I pull the
   Source code from GitHub.

from hadoop-cluster-docker.

To build a docker image:

1. Write Dockerfile
2. Run "docker build command"

Before you push your dockerfile into the docker hub. Inside your dockerfile i container what ?

why we stiill need to get the source code from GitHub?

from hadoop-cluster-docker.

You can just pull all required images by running "docker pull".And you don't have to build image by your self. In this case, you don't need Dockerfile.
However, to run the project, you need to get the shell script "start-container.sh".

Don't need Dockerfile ?

we still sudo docker pull kiwenlau/hadoop-master:0.1.0?

from hadoop-cluster-docker.

Let say I would like you build my own docker image. Don't mind at least tell how you go about process one of the image here therefore I have a better understanding !

Just would like to clear my confusion since we no need to build our own docker images why we still need sudo docker pull kiwenlau/hadoop-master:0.1.0?

from hadoop-cluster-docker.

Using following command to build hadoop-base image:

cd hadoop-cluster-docker/hadoop-base
sudo docker build -t kiwenlau/hadoop-base:0.1.0 .

from hadoop-cluster-docker.

what is the purpose of sudo docker pull kiwenlau/hadoop-master:0.1.0?

from hadoop-cluster-docker.

The purpose of "sudo docker pull kiwenlau/hadoop-master:0.1.0" is to download docker image.

You should spend more time on studying Docker

I can not explain ever details...

Thank ! I re-read through and have full understand !!! you are an awesome developer 5 start for you !!!! 👍 👍 👍 👍 👍 👍

@kiwenlau @TaylorNm08z you don't need any sudo. You can just pull. Even for building on your machine, you don't need sudo. It's because Docker demon runs as a root user. Read more here: https://docs.docker.com/engine/installation/linux/ubuntulinux/

from hadoop-cluster-docker.

You need sudo to run docker command when you are not root user.
