Welcome back.

The previous steps we built a image for the python Hallowell application and we ran it on our local machine.

However we would want to share that image with others.

I want my friends to be able to run that image as well.

How do I do that.

I can push it to Docker Hub.

One of the important things to remember is to have the docker dot com is a public registry so if you are pushing anything out there anybody else can use it.

So typically in quadruplets they would use private Docker repositories or they would use some repository which is on inside the cloud.

For now let's use Docker Hub because that's already available for free for us.

What you need to do to be able to use alcohol is to sign up for Docker Hub.

So going to dealing sign up for Docker Hub and Oh here you can actually enter your Uncle Eddie your email address and your password.

Make sure that you get through the capture do will sign up.

Once you click the sign up you should get an email make sure that you verify yourself and then your Docker Hub account is ready.

Make sure that you know down the docker I.D. Docker rate is very very important.

Whenever you are logging to Docker Hub you would use the docker I.D. and not the email to log in to help you lose the docker I.D. and the password.

How do you log into Docker Hub all that you need to do is to execute the command Dockery again so once you execute the command Docker log in it will ask you for your user I.D. and password.

You need to enter whatever you have entered in here.

As you rightly Docker rightly and you need to enter the password or you would have entered here when creating the account would be the password so enter that and make sure that you have logged in before you'd be able to push the image out to the local hub.

Now once you are able to log in there is one more important thing before you'd be able to push the image out.

So if you do a docker images right.

So if you see my user data my Docker I.D. is in 28 minutes and the repository name I am using is in 28 Min slash hello world by then where is this coming in from where is this repository name coming in from when we build the email to the command which we used to build image.

Let's get there.

OK.

When we build the image we passed in in 28 min in here.

So what you need to do is if you want to be able to be sure.

Image you need to replace this specific in 28 men with whatever you were Doctor I.D. So you cannot push.

In 28 Min Docker Hub what you need to do is you need to replace it with your doctor i.e. build the image again and then push that image out to the doctor so you can only push images with repository  ames starting with your doc Rady followed by a slash followed by the name you are giving to your specific application of the entire thing.

Here would be your repository in the repository name should contain.

You will use the right to your doctor right.

And this back can remain the same.

So you need to execute this command and you can run that again thing so you can replace in 20 min with your doctor lady and run this here and then you can do a push the command for push is surprisingly simple so all that you need to do is do backup push and I need to take in 2018 Hallowell by then colon zero point zero point two DOD release.

That's it.

That all is needed for you to be able to push made to Docker Hub so the three steps were one to log in using Doc and log in.

The second step is to make sure that your I.D. So instead of my doctor right in here you need to use your doc variety and be limited for it.

The third step is to execute the doc a push and that's it.

You can see that it would push the image out to the doc so you can see that the image is now being pushed out.

It will take a long while it should like.

Worst case it would take about a minute or so to be able to push this image out and you would see within a short while noticing the image is pushed out so you can see that the image is now being pushed out.

Now how can I check if these images are available elsewhere.

I'll go to the doctor dot com slash you slash in 28 Min.

That's my doctor.

You need to replace this with your dog right.

So step into the admin you need to replace it with your doc Grady and you'll be able to see that there is a Hello World python in here and if you go to the tags earlier we just had one bag in here.

Zero point zero point one dot release.

And now we have another bag in here as well.

Zero point zero point two dart release and you can see that it's updated a few seconds ago by in 28 Min.

Isn't that cool.

So now we have a major which is present in here as an exercise.

I would recommend you to try and find this specific thing as well.

If you don't really want to create an image with your doc already that's fine too.

All that you need to do is you can use this image name and try to run it and see if everything works out fine in step.

We learned how to push a Docker image to Docker Hub.

I'll see you on the next step.
