rabbitmq:

mem_limit: 300m
ports:
- "5672:5672"
- "15672:15672"
environment:
RABBIT_URI : amqp://guest:guest#rabbitmq:5672
zipkin-server:

Answer 1

I had faced similar issue and it was fixed by adding restart: always key-value for zipkin-server. You can specify the RABBIT_URI for zipkin-server, but rabbitmq might not require it to be specified. And if you are planning to save the traces in mq in case zipkin is down, adding this dependency to zipkin-server can help:
depends_on:
- rabbitmq
So the .yaml snippet will look like:
rabbitmq:
image: rabbitmq:3.5.3-management
mem_limit: 300m
ports:
- "5672:5672"
- "15672:15672"
zipkin-server:
image: openzipkin/zipkin:2.23
mem_limit: 300m
ports:
- "9411:9411"
environment:
RABBIT_URI: amqp://guest:guest#rabbitmq:5672
depends_on:
- rabbitmq
restart: always

Answer 2

You can make this a little easier if you write down what you are trying to achieve and properly format the error and the yaml. If you do it you will have a better chance to spot this in the last line:
java.io.UncheckedIOException: Unable to establish connection to RabbitMQ server: rabbitmq: Try again zipkin-server_1
This means that the application is not able to connect to the host, try to update the host and use localhost if you are outside of the docker network i.e.: on the host and use the container_name if you are inside. I would also suggest defining the container_name, here is an example for zipkin and here is one for rabbit
Btw, I'm not sure what is the intention with RABBIT_URI inside of the rabbitmq service in your docker-compose.
