Creating a Docker Hub account

Creating a Docker Hub account is a straightforward process. Follow these steps to create your Docker Hub account:

1. Open your web browser and go to the Docker Hub website: [https://hub.docker.com/](https://hub.docker.com/).

2. On the Docker Hub homepage, click the "Sign Up" button in the upper right corner.

3. You will be taken to the Docker Hub sign-up page. Here, you have the option to sign up using your Docker ID or by connecting with your GitHub or Bitbucket account. To create a Docker ID, enter the following information:

   - Username: Choose a unique username for your Docker Hub account.

   - Email Address: Enter a valid email address.

   - Password: Create a secure password for your account.

   - Confirm Password: Re-enter the password to confirm it.

4. After entering the required information, click the "Sign Up" button.

5. Docker Hub will send a verification email to the address you provided. Open your email inbox and locate the email from Docker Hub.

6. In the verification email, click the "Verify email address" button or follow the provided link to confirm your email address.

7. Once your email address is verified, your Docker Hub account will be created, and you will be logged in automatically.

Congratulations! You now have a Docker Hub account, which you can use to publish and share Docker images

Sharing your first image 

1. Build the Docker Image.  This is the same as we did previously:

      docker build -t dev-ops-hello-worldapp .

2. Before pushing the image, you need to log in to your Docker Hub account using the `docker login` command. You'll be prompted to enter your Docker Hub username and password:

      docker login

3. To push the image to Docker Hub, you should tag it with your Docker Hub username and the desired repository name. For this helloworld I issued:

   docker tag dev-ops-hello-worldapp terryalsdorf/devopshelloworld:latest

4. Finally, use the `docker push` command to push the image to Docker Hub:

   docker push terryalsdorf/devopshelloworld:latest

   This will upload the Docker image to Docker Hub.

5. Verify on Docker Hub: You can visit your Docker Hub account on the web to verify that your image has been successfully pushed and is available in your repository.

That's it! You've now pushed your first Docker image to Docker Hub. You can share this image with others or use it for deployment on various platforms.
