Container stuck when calling start

[ruiarodrigues]

Hi!

I'm trying to use the testcontainers for Ruby to use a minIO image in my rspec. I tried multiple ways but didn't succeed. The container keeps being stuck forever when calling start. I thought it was the way I passed the arguments to the container but I think it's not.
So I tried to use one of the example with memcached

    puts 'Starting'
    memcached = Testcontainers::GenericContainer.new("memcached:latest").with_exposed_port(11211).start
    puts 'Started'

And the 'Started' log is never written.
I can see that the image has been downloaded by the test container but then nothing. It get stuck.

I'm using the minIO testcontainer for java in JUnit tests and it works fine. So the docker part is working fine in my laptop.

But when using with RSpec it doesn't work. I'm using it like this (and tried many different ways using with_xxx):

@container = Testcontainers::DockerContainer.new(image: "minio/minio:RELEASE.2023-10-25T06-33-25Z",
                                                     port_bindings: 9000,
                                                     command: %w[server /data]
                                                     )
    @container.add_wait_for(:logs, /1 Online, 0 Offline/)
    @container.start

How can I understand what's going on?
Can 'start' be called anywhere in the RSpec?

@ruiarodrigues thanks for reporting this, I'll investigate it during the next days and hopefully return with some answers

@ruiarodrigues can you provide a minimal script to reproduce this?
