First, do not use SSH, block 22 (and RDP) ports on network ACL level entirely and use SSM session instead. Also be sure only to allow ports you need (80,443 for example) in EC2 instance security group. Installing and running Docker on Ubuntu is trivial once you get into it. There is obviously more things to be done if you want run this in production (SSL, load balancing, etc). I would also recommend to look into ECS Fargare or forgo EC2 entirely but that’s a bit too advanced. More on reddit.com

Sounds like you might not have Internet access for the VPC. I'm somewhat new to AWS and made a checklist for a recent project that handles this for me. Here is my checklist:: # Create a VPC # Create a subnet (optional: enable MapPublicIpOnLaunch) # Create a Security Group (must have both Inbound and outbound rules set) # Create an Internet Gateway # Attach Internet Gateway to the VPC # Create a public route table and associate it with the public subnet # Add a default route to the public route table that sends all internet-bound traffic through the Internet Gateway # Create EC2 Instance (optional: Enable AssociatePublicIpAddress here if the subnet is not enabled for public ip on launch) Would love to know if this helps you resolve the issues you're seeing.
