Do I have to specify the port for images with one port exposed?

[slsyy]

# Dockerfile
EXPOSE 11211
CMD ["memcached"]

// Code
port := "11211/tcp"
rq := testcontainers.ContainerRequest{
	Image:        "memcached:1.6.10",
	ExposedPorts: []string{port},
	WaitingFor:   wait.ForListeningPort(nat.Port(port)),
}

memcachedC, err := testcontainers.GenericContainer(context.Background(), testcontainers.GenericContainerRequest{
	ContainerRequest: rq,
	Started:          true,
})

url, _ := memcachedC.Endpoint(context.Background(), "")

Is there any way to have the same functionality without specifying the port manually in a code?

I tried to make this work as well and eventually settled for parsing the image definition itself to discover the port

@slsyy Do you mean wait.ForListeningPort(nat.Port(port)) ?

What if several ports exposed?

I think we can close this one, as https://github.com/testcontainers/testcontainers-go/pull/468 was merged and released in v0.14.0, but please let us know if you need anything else here and feel free to reopen it.

Thanks for your time!
