Steps to create containers on Azure

Below are the steps to create containers on Azure:

1. Log in to the Azure Portal: Go to https://portal.azure.com/ and sign in to your Azure account.

2. Create a new container registry: From the Azure Portal, click the "+ Create a resource" button on the left-hand side menu. Then, search for "Container Registry" and select the appropriate option.

3. Configure the basic settings: Provide a name for your container registry, select the appropriate subscription, and choose a resource group for the registry.

4. Choose the pricing tier: Select the pricing tier for your container registry based on your needs.

5. Configure the networking: Choose the virtual network and subnet for your container registry, and select whether you want to use a public or private endpoint.

6. Configure the authentication: Select an authentication type and configure the credentials for your container registry.

7. Create a new container group: From the Azure Portal, click the "+ Create a resource" button on the left-hand side menu. Then, search for "Container Instances" and select the appropriate option.

8. Configure the basic settings: Provide a name for your container group, select the appropriate subscription, and choose a resource group for the group.

9. Choose the image and size: Choose the container image you want to run and specify the number of containers to run.

10. Configure the networking: Choose the virtual network and subnet for your container group, and select whether you want to use a public or private IP address.

11. Configure the environment variables: If necessary, specify any environment variables required by the container image.

12. Review and create: Review all the settings you have configured for the container group and click the "Create" button to create the container group.

13. Wait for the container group to be deployed: It may take several minutes for the container group to be deployed and become available.

14. Access the container group: Once the container group is deployed, you can access it by using the IP address or the domain name.

Now you can deploy and run your containerized applications in the cloud.

What are Containers?

Containers provide a consistent, isolated execution environment for applications. They're similar to VM's except they don't require a guest operating system. Instead, the application and all its dependencies are packaged into a "Container" and then a standard runtime environment is used to execute the app. This allows the Container to start up in just a few seconds because there's no OS to boot and initialize. You only need the app to launch.

The open-source project, Docker, is one of the leading platforms for managing Containers. Docker Containers provide an efficient, lightweight approach to application deployment because they allow different components of the application to be deployed independently into different Containers. Multiple Containers can be run on a single machine, and Containers can be moved between machines. The portability of the Container makes it easy for applications to be deployed in multiple environments, either on-premises or in the cloud, often with no changes to the application.
