How do I specify a range of ports like -p 5080-5090:5080-5090?

I need to specify a range of ports like the docker command lets you do -p 5080-5090:5080-5090.

I tried the following:

var container = new ContainerBuilder()
    ...
    .WithPortBinding("5080-5090", "5080-5090")
    .Build();

Which gives this error:

Unhandled exception. Docker.DotNet.DockerApiException: Docker API responded with status code=BadRequest, response={"message":"invalid port specification: \"5080-5090\""}

And I tried .WithPortBinding("5080-5090:5080-5090") which gave the same error.

How would I go about this?

I'm afraid that's not supported out of the box. We can add it without much effort, but I'm curious, would you expect this to work with random host ports? We don't recommend using static port bindings since they don't support parallelization and might conflict with other services running on the host (especially when working with others).

You could probably work around the missing API like this:

var containerBuilder = Enumerable.Range(5080, 10)
    .Aggregate(new ContainerBuilder().WithImage("alpine:3.17"),
        (builder, port) => builder.WithPortBinding(port, port));

var container = containerBuilder.Build();

I'm trying to start the pinecone-local Docker container, following their documentation.

docker run -d \
--name pinecone-local \
-e PORT=5080 \
-e PINECONE_HOST=localhost \
-p 5080-5090:5080-5090 \
--platform linux/amd64 \
ghcr.io/pinecone-io/pinecone-local:latest

Your proposed solution may work, I'll try it out.

I'm trying to start the pinecone-local Docker container, following their documentation.

This would be something like:

var containerBuilder = new ContainerBuilder()
    .WithImage("ghcr.io/pinecone-io/pinecone-local:latest")
    .WithName("pinecone-local")
    .WithEnvironment("PORT", "5080")
    .WithEnvironment("PINECONE_HOST", "localhost")
    .WithCreateParameterModifier(parameterModifier => parameterModifier.Platform = "linux/amd64")
    .WithWaitStrategy(/* TODO: Add a proper wait stragey. */);

var container = Enumerable.Range(5080, 11)
    .Aggregate(containerBuilder, (builder, port) => builder.WithPortBinding(port, port))
    .Build();

await container.StartAsync()
    .ConfigureAwait(false);

However, as mentioned above, we do not recommend using static container names, port bindings, or similar configurations.

If you'd like to take a look at it, I think we can extend the builder API to support port ranges. However, I'm not sure if GetMappedPublicPort(ushort) should support port ranges as well. Perhaps we could return a dictionary containing all mapped public ports.
