The objective of this article to explain how to clone a project from Github, how to build and run a project using docker. To execute the following commands in this article we are using Windows Power Shell app. Copy the below link to clone doodle project as sown in the below snapshot.
git clone https://github.com/docker/doodle.git
Open the Power shell app in windows, paste the above link and enter to clone the doodle project into your local from Github. Look at the below screenshot, click on Next Step button to proceed further.
Use the below command to build the doodle project which you cloned. Look at the below snapshot to get the command.
cd doodle\cheers2019 ; docker build -t subbareddyroyal/cheers2019 .
If you have selected the checkbox to use Windows containers instead of Linux containers, you may end up with these build problems with windows containers in Docker.
Look at the complete build log in below,
PS C:\Users\USER\doodle\cheers2019> docker build -t subbareddyroyal/cheers2019 .

a non-Windows Docker host.
All files and directories added to build context will have '-rwxr-xr-x' permissions.
It is recommended to double check and reset permissions for sensitive files
and directories.
Now project build is successfully completed. Then you go to the next step to get the command to run. Look at the below snapshot.
docker run -it –rm subbareddyroyal/cheers2019
When you run the above command, you can see the screen like below and moving the docker symbol.
Now issue the below command to ship this into docker.
docker login ; docker push subbareddyroyal/cheers2019
Look at the below image to see the Pushing progress into Docker. Docker will expect you to provide the authentication details to complete the login process. Once you authenticated successfully, Docker starts the actual Push process.
I hope this is helped you to understand the basics of the Docker. Thanks for visiting my website.
