auto-ssl | SSL front end for a Node/Express app | Continuous Deployment library

It's a tricky one because it could be at any layer of your stack.

A couple of pointers:

• Check the logs of the kube-proxy running on the node in question.

You don't deploy to DockerHub. You push to docker hub. Hopefully this command might be what you're looking for: docker-compose push

I am not sure what is the purpose of your project, but here is my Dockerfile that uses puppeteer that is a Google Lib that wraps chrome_headless and allow you to use it more easily.

Here you can find an official example and here is the official documentation of puppeteer with great community suppport.

This is my Docker file that runs a npm script after building a container with puppeteer, node and chromium dependencies.

Where should I store my 'root' docker-compose.yml file.

Many orgs use a top level repo which is used for storing infrastructure related metadata such as CloudFormation templates, and docker-compose.yml files. So it would be something like. So devs clone the top level repo first, and that repo ideally contains either submodules or tooling for pulling down the sub repos for each sub component or microservice.

In a docker-compose.yml file, Can the nginx serve mount a volume from my frontend service without any ports and serve that directory?

Yes you could do this but it would be dangerous and the disk would be a bottleneck. If your intention is to get content from the frontend service, and have it served by Nginx then you should link your frontend service via a port to your Nginx server, and setup your Nginx as a reverse proxy in front of your application container. You can also configure Nginx to cache the content from your frontend server to a disk volume (if it is too much content to fit in memory). This will be a safer way instead of using the disk as the communication link. Here is an example of how to configure such a reverse proxy on AWS ECS: https://github.com/awslabs/ecs-nginx-reverse-proxy/tree/master/reverse-proxy

I can't seem to deploy a proper production with Docker with my 3 tier application in ECS Cluster. Is there any good example nginx.conf that I can refer to?

The link in my last answer contains a sample nginx.conf that should be helpful, as well as a sample task definition for deploying an application container as well as a nginx container, linked to each other, on Amazon ECS.

How do I auto-SSL my domain?

If you are on AWS the best way to get SSL is to use the built in SSL termination capabilities of the Application Load Balancer (ALB). AWS ECS integrates with ALB as a way to get web traffic to your containers. ALB also integrates with Amazon certificate manager (https://aws.amazon.com/certificate-manager/) This service will give you a free SSL certificate which automatically updates. This way you don't have to worry about your SSL certificate expiring ever again, because its just automatically renewed and updated in your ALB.
