How to create aws cluster with infrastructure as ec2 and asg using aws cli

In the AWS online UI, when creating a cluster, a user can select these additional options:

• Infrastructure:

  • Amazon EC2 instances
    • Auto Scaling group: Create new ASG|select
    • Provisioning model: On-demand|Spot
    • Container instance Amazon Machine Image: Amazon Linux image etc.
    • EC2 instance type: t2.micro
    • EC2 instance role: Create New Role|Select
    • Desired capacity: min: 0, max 5 etc.
    • SSH Key pair:

• Networking settings:

  • VPC:
  • Subnets:
  • Security Group:

When using the terminal - aws cli, the options are limited for creating a cluster.

See example:https://awscli.amazonaws.com/v2/documentation/api/2.3.2/reference/ecs/create-cluster.html

It is not possible to select most of these other options via the aws create-cluster command. At the very least I want to be able to select EC2 and ASG.

How is this typically done via aws cli?What other commands would I need to run in aws-cli to replicate what the UI "Create Cluster" does?My end goal is to push docker images to aws ec2 using aws-cli commands only, before moving onto other orchestration tools.

I don't need specific implementation details. Just the core steps.ie

• create-cluster
• create task definition
• what's next and in what order?

I have so far followed the instructions:https://docs.aws.amazon.com/AmazonECR/latest/userguide/getting-started-cli.html

Step 1 - step 7.

I cannot find anymore tutorials in AWS documentation to describe my intentions above.
