Building Container Images Using Dockerfiles

1- Create Dockerfile

~ vi Dockerfile

FROM httpd:2.4
RUN apt update -y && apt autoremove

• Dockerfile always start from FROM keyword and after it we tell the image name like we are telling here httpd of which we want to create our container.
• RUN whatever we are going to write after RUN it will be run in our container.

~ docker build -t wigetfactory .

• Here you can see that we are creating our image from our Dockerfile and giving it a name which is wigetfactory

2- Let's update our Dockerfile and put our website content in it.

FROM httpd:2.4
RUN apt update -y && apt autoremove
rm -f /usr/local/apache2/htdocs/
WORKDIR /usr/local/apache2/htdocs/
COPY ./web .

• Here you can see that I am changing my container work directory using *WORKDIR * command and then copy my website content from my host directory to the container location which is htdocs.

• Let's run our Dockerfile again.
  

~ docker build -t widgetfactory:0.3 .

Here will be the output of it

• Now run container using the image.

docker  run --name weebproject -d -p 80:80 widgetfactory:0.3
