I am an experienced Developer, Trainer, and eventual Speaker. Lifelong learner, eager to learn and share knowledge. A bit introspective. Keep coding. Be humble. Help others.
Hum.. That's unfortunate, I will run this again and double check but definitely worked before? What O.S are you running? Did you check the ports if they're all available? Did you update any versions of the images in the compose-file before running? Because KAFKA_ZOOKEEPER_CONNECT is actually defined.
Also I would check your yml file for proper identation and formatting, yml can be very tricky for those. Make sure it's compliant. I've never used but you could try this one: yamllint.com/ or add a yml lint to your IDE and make sure it's properly formatted.
