This post will be in two parts. We have two instances on AWS, and these are rolled out one at a time, validated and then the old one removed. The reason why the local ECS cluster has not updated is because there are no other instances to deploy the application onto. This would allow us to deploy more local machines, and then ECS Anywhere would be able to deploy those applications across those instances. We now have a secure connection between our AWS environment and our local environment. When we ran the CDK script to provision the ECS cluster, it output the name of the ECS Cluster, so lets assign that to an environment variable as will need to use that in the next step. We are now ready to deploy the AWS resources using AWS CDK. One thing that I did manage to do via the console, but have not figured out yet how to do via my CDK application is to incorporate the local Raspberry Pi into the first ECS cluster.

The first stack we will deploy is the VPC which will deploy. Now save and reboot and your nat type will be open. Once this is up and running, when we refresh, you should now see that this is running the same version. Now I need to grab the latest version from that output, and then use that to update the running service. Repeating the steps above, I added another local machine – this time, my main Ubuntu desktop which is running on an old x86 machine. With our local instance, we only have the single Raspberry Pi. To do this, from the AWS Console, go to the Amazon ECS Cluster view, select the local cluster (mine is called mydc-ecs-extcluster) and then click on the TASKS tab. There are only single options for PLATFORM/SOFTWARE so click on the DOWNLOAD button, which will download a text file. You will need to click on the DOWNLOAD CONFIGURATION (highlighted above/arrow). If you restart your Pi, you will need to repeat these steps.
You may also need to move/rename the /var/lib/amazon/ssm if you get issues around the agent failing to install on subsequent attempts. Make sure you check them out if you get stuck or want to dive a little deeper into this setup. This is outside the scope of this post, but if you get errors during the VPN setup with missing libraries, it is likely they are the cause of the problem so make sure you update everything before proceeding. Once you are done with DMZ host configuration. It is in these situations that a DMZ host can be setup. The original ECS Cluster has a security group setup that controls access from the Application Load Balancer to the EC2 instances, on the target port (8080). That was for the subnet that those instances were on, not my local network (which is on a 192.168.1.0/24 CIDR). Port forwarding doesn’t consume your Internet speed or Electricity or anything. Open a internet browser. Check the status of your network by using a mobile device to connect to the Internet. It’s a feature available in most routers, which allows you to redirect communication request from your Private IP on the Internet.
A DMZ ensures a private network or LAN remains secure, keeping unwanted traffic and nefarious mobile devices away. This will route all traffic for AWS via the Raspberry Pi VPN gateway (192.168.1.6) we just created. It will take around 5-10 minutes for the code to update and deploy to the ECS Cluster. 86 and arm built containers, creates the container manifest files, tags them, uploads them to the Amazon ECR repository and then finally kicks of the deployment to our ECS cluster. In this section, we ought to fill in the username and password and then turn on the DMZ (Demilitarized Zone) function of the router. You can even set up a BBS on DM7020 if you go on using this function! As mentioned previously, using port forwarding or virtual servers should allow for the vast majority of applications to function properly, but for the few that cannot be configured in this way, the DMZ host may be used. PortMapper. PortMapper is yet another free port mapping software that allows you to forward any port any IP address. Does Port forward cost money? Does port forwarding affect other devices? All other devices sit inside the firewall within the home network.
