1. Nodes: Connection between the cloud services provider such as MS Azure and AWS to run up containers.

2. Data Processing: Provide big data processing as a service package.

3. Cloud Repository: Provide a platform where we can store a number of versions in a specific Docker Image.

4. Continuous Implementation: Connect with GitHub and build a continuous integration pipeline.

5. App Deployment Scale the Infrastructure and Containers with deployment.

6. Consist Deployment it can be automated deployment.

Docker Cloud Features

The folowing are the features of Docker Cloud:

• Container Orchestration: It provide the feature such as Container orchestration to orchestrate the containers at scale and facilities the users to deploy and manage scale applications across the multiple cloud environments seamlessly.

• Monitoring and Logging: It offers the monitoring and logging capabilities with the insights of container performance, resource utilization helping users in identifying and resolving the issues proactively.

• Security: It provides the features of securing the containerized applications such as image scanning for vulnerabilities, access controls and network policies.

Steps for Containerization Process

Step 1:

Login to the Docker Cloud site

Step 2:

Now we connect to the cloud provider so, first ensure that you have the right AWS keys. That can be taken from the AWS Console.

• Once you logged in, go to the security credential section, then make a note to access the keys which will be used from Docker Hub.

Step 3:

Next, create a policy in AWS that will give permission to view EC2 instances. for creating a go-to profile section in AWS. Click on to create policy button. save the policy name as “dockercloudpolicy”

{
"Version" : "2017-10-17",
"Statement" : [ {
   "Action" : [
       "ec2:*",
       "iam:ListInstanceProfiles"
       ],
       "Effect" : "Allow",
       "Resource" : "*"
} ]
}

Step 4:

After the creation policy, you need to come back to Docker Hub and make a container image using python or Ngnix, Ubuntu, or Redis and deploy.

How does Container enhance the Deployment Process ?

With Containers, these processes are actually simplified. now the development and operations team could be on the same page using the containers, and no configuration is needed on the server, except the Docker runtime server. That is just a one-time effort.

Developers and Operations teams can stay on the same page through the overall development process thanks to packaging the application in a container.
