Step 2: Build an image from your Dockerfile

learn about the build process

Start

🐳 docker as the image or container to get and load the image from the internet or local, then save them into the docker in the docker.
😆 for me, it is the database for image :P

💻 My laptop is: 🍎 Mac air -- OS X EL Capitan -- Version 10.11.4

🐳 hub

🖱️ find the search from the right top on the page

hub Here is the box you need find whalesay

⬆️ enter the text below on the search box as above then 🖱️ click enter/return
whalesay

resource page

link

Find this row and select it https://hub.docker.com/r/docker/whalesay/

From this page, you can find the way to help you load the image from the docker, there are thousands of images on the docker include some large company such as IBM, Google and other else. As you enter the web page, for example the whalesay, you can see the "how to use this image" for helping using the image in the terminal

so...
here is the code you need to enter to get the whalesay image (i am really confused what the expression the whale will say, let us take a look by enter the below code first 😃 )

$ means the start on the terminal, you don't need to enter it within the terminal, if you see in the other place. In here, i prefer delete it and give you the code you need to enter in the code mode.

docker run docker/whalesay cowsay boo

whale say !!

Here is what the terminal display after the "docker run docker/whalesay cowsay boo"

oh, actually, you can see the boo on the left top which is different from the whale before...

..... it says:"boo"!!

---

Now, we try to see what kinds of images we have so far in our own containers:

docker images

docker images

There is two packages of images in the docker in your local, after we making sure that the 🐳 "whalesay" package

docker run docker/whalesay cowsay boo-boo

boo

🐳 whale now is your guest and say boo to you

---

Step1: write a docker file

• open the whale terminal and let us start 😄

  mkdir mydockerbuild
  

mkdir (make directory): create a new directory

cd mydockerbuild

• open the new created directory, cd means open in the terminal as you seen before (cheatsheet is on the bottom of the page )

touch Dockerfile

create a Dockerfile in the directory

ls Dockerfile

read the Dockerfile

 open -e Dockerfile

There is another window coming out, here is the text file you can enter the text

text file window

Type the text below in the text file :

  FROM docker/whalesay:latest

• FROM: the keyword to tell where does the image coming from and execute the action the image after from

enter the text

RUN apt-get -y update && apt-get install -y fortunes

CMD /user/games/fortune -a | cowsay

whole text

then use the File>save or command -S to save the file

run in terminal

As you run in the terminal, you can see the text was shown.

Step 2: Build an image from your Dockerfile

cat Dockerfile

cat: it is not the cat 🐱 , but the action of "CATCH" miao~~

docker build -t docker-whale .

successful built
