AWS Ec2-需要在EC2实例之前创建VPC和Su.nets吗？

Question

I am trying to create a basic ec2 instance on which I will run a docker container that runs a spring boot web app.

When I go to create the instance I see the below screen.

Do I need to create a VPC and su.nets first before I can create an Ec2 instance? And is this a new feature of AWS ?

I want my instance and docker container to be accessible via http and https on the public inte.net as spring boot exposes a rest api.

Answer 1

If you don't already have one, you can create your own VPC or use the default one then create a public su.net (with auto-assigned public addresses) in this VPC.

I would recommend to directly create your own VPC.

Since you want your instance being reachable on http and https you want to create a security group that allows connections on ports 80 & 443 and allows connection on port 22 from your personal IP address only .

The port 22 will allow you to connect via SSH in the instance to set up your docker container.

Hope it helped!
