What is a DockerFile?
It is a text file that has all commands which need to be run for building a given image.
Using Docker File we can build custom image for our application.
πŸ’₯πŸ’₯ Today's Technotes πŸ’₯πŸ’₯

Sample Docker File.
#This is a sample Image
FROM ubuntu
MAINTAINER hitechinstitutionemail@gmail.com
RUN apt-get update
RUN apt-get install –y nginx
CMD [β€œecho”,”Image created”]
πŸ’₯πŸ’₯ Today's Technotes πŸ’₯πŸ’₯

What is FROM in Docker File?
FROM tells which base you would like to use for creating your docker image.
Since we are using Centos:7, it's mentioned there. We can use other OS like centos:6, ubuntu:16.04, ubuntu etc
πŸ’₯πŸ’₯ Today's Technotes πŸ’₯πŸ’₯

What is MAINTAINER in Docker File?
Both fields MAINTAINER & LABEL Remarks are called labels.
They are used to pass information like the Maintainer of the docker image, Version number, purpose, or some other remarks.
We can add a number of labels but it's recommended to avoid unnecessary labels.
πŸ’₯πŸ’₯ Today's Technotes πŸ’₯πŸ’₯

What is RUN command in Docker File?
Now RUN command is responsible for installing or changing the docker image as we see fit.
Here we have asked RUN to update our system & then install apache on it.
We can also ask it to create a directory or to install some other packages.

What is ENTRYPOINT & CMD in Docker File?
ENTRYPOINT & CMD are both used to define an executable that should run once docker is up.
On ENTRYPOINT, we define an executable & with CMD, we define additional parameters that are required for ENTRYPOINT.
Like here, we have used ping with ENTRYPOINT but it requires an additional parameter, which we provided with CMD.
CMD: Can be overwritten | ENTRYPOINT: Can't be overwritten
