I am running Docker on my ubuntu laptop. This is just the development environment. Once all the bugs are run down I will move it to my Lightsail environment on AWS. As part of my "due dilligence" I need to make sure that I am securing user's data. Thus I plan to use AWS Secret Manager. To do this I am required to set up https with TLS on my ubuntu laptop (which is running Docker).
I was told by a Docker expert I use sometimes that setting up a cert on a Docker PC is "impossible". Is this true? Can a LE cert be used?
