Publish multiple ports for Dockerfile app

I want to publish multiple ports for my app that is built from a Dockerfile using flyctl deploy. As far as I know, we don’t have access to the docker run command, if I did I believe I would want it to look like this:
docker run -p 80:80 -p 443:443 -p 10001:2019 my-app-image

How can I accomplish this?

Below is my fly.toml:

app = "my-app"

destination = "/config"
source = "config"

# port 80 mapping
internal_port = 80
protocol = "tcp"

port = "80"

# port 443 mapping
internal_port = 443
protocol = "tcp"

port = "443"

# port 2019 mapping
internal_port = 2019
protocol = "tcp"

port = "10001"

Assuming you want multiple ports open publicly, that fly.toml looks correct. Is it not working? You may need to give it a few minutes after a deploy when ports change.

If you just want ports available over the private network, you don’t have to do anything. Anything you listen on in the container works.

So the docker run command that runs looks at the toml file to determine what ports to publish on the docker image?

If I understand what you’re asking right, yes. The fly deploy command sends the config. We use the [[services]] to block configure our load balancer for your app. The load balancer sends traffic in the defined ports to all instances of your application.

The EXPOSE and -p args Docker uses don’t really mean anything in our environment. They control how Docker sets up IP tables rules to forward ports on a local system.
