What ENTRYPOINT commands are needed in the dockerfile that adds php files into a container

Question

I have created a Dockerfile that adds the php files into the devopsedu/webapp container. Could you please let me know how to start the php service now? What I mean is that what should be my ENTRYPOINT commands in the Dockerfile?

Answer 1

Hope you are doing good!

In this step, you have to create a dockerfile and the base image should be devopsedu/webapp. And you have to write dockerfile in such a way that it should run the PHP application. Please find the below sample docker file which uses devopssedu/webapp as the base image and then it runs the PHP application. 

FROM devopsedu/webapp 
ADD proj /var/www/html
RUN rm /var/www/html/index.html
CMD apachectl -D FOREGROUND

Create a docker file as mentioned above and continue with the next steps of the project.

I hope this helps.

which files form given sample website repository need to be added under 

/var/www/html

Please elaborate a little bit here.

Hey Harish, /var/www/html is the directory where your website files are stored. These files include the codes, images etc used for the website.

How does this docker file run the php application? Is the application code inside the image? What about the application in https://github.com/edureka-devops/projCert . I'm bit confused. Pls clarify.

The application code is moved or copied inside the container and a docker image is build. An image is created. Now when you run this image, the php application will get executed.

Hi Trisha, to add to your answer, how can I run the image, I did exactly how it was said above and I can only see the apache page appearing.

In the above code the image has pre installed php. When You run that file it will launch a container with php.
