In my previous example, I didn't use a load balancer, and could only assign a DNS record to the auto-assigned public IP. I also couldn't put a cert in front of my app, or redirect 80 to 443.

Create a new service using the load balancer option
In the ECS Service Load balancing options, I created an Application Load Balancer, and also created a new listener and target group. The target group listens on port 80 and routes to port 5000 for my Flask app.
Once the ALB was deployed, I added an additional listener on the ALB for HTTPS traffic, and configured it to forward to the target group I previously created in the ECS service deployment. I also attached my ACM cert in the 'Secure listener settings' for this Listener. I also needed to modify the first listener for HTTP/80 traffic, and configured it to 'Redirect' HTTP/80 traffic to HTTPS/443.
Configuring the 443 listener:
Configuring the port 80 listener to redirect:
Add DNS A record for ALB
The last step was straight forward, and I just needed to add an A record for connect.joshweepie.com, configure it to route traffic to the 'Alias to Application and Classic Load Balancer' option, and select my ALB.
