Specifying `--endpoint-url` gets an "Unable to find LocalStack endpoint for service" error

[niauah]

I was running a seperate testing Localstack host that exposes different ports with the docker-compose file like this:

version: "3.8"

services:
  localstack-testing:
    container_name: "${LOCALSTACK_DOCKER_NAME-localstack_testing}"
    image: localstack/localstack
    ports:
      - "127.0.0.1:5510-5559:4510-4559"  # <--Port number changed here
      - "127.0.0.1:5566:4566"            # <--Port number changed here
    environment:
      - LOCALSTACK_SERVICES=${SERVICES-}
      - DEBUG=${DEBUG-}
      - DATA_DIR=${DATA_DIR-}
      - LAMBDA_EXECUTOR=${LAMBDA_EXECUTOR-}
      - HOST_TMP_FOLDER=${TMPDIR:-/tmp/}localstack
      - DOCKER_HOST=unix:///var/run/docker.sock
    volumes:
      - "${TMPDIR:-/tmp}/localstack:/tmp/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

The Localstack service was started by docker-compose up command and went up normally.

When I tried the awslocal --endpoint-url http://localhost:5566/ help command, an error occured:
ERROR: Unable to find LocalStack endpoint for service "http://localhost:5566/"

However, when using aws instead of awslocal, the command was successfully executed and the help message was shown.

If any extra information is needed to reproduce the situation, please let me know.

Thanks for reporting @niauah . This is a bit of a limitation with the awslocal command line - the first parameter needs to include the service name, e.g., you can run this command:

awslocal s3 --endpoint-url http://localhost:5566/ help

So, for general help, please use aws help, and for service-specific help, you can use awslocal. Hope that helps, thanks.

Thanks for the reply! I can reproduce the result, and this solves my problem.

I just tried awslocal help --endpoint-url http://localhost:5566 and it also works, suggesting that help is an acceptable first parameter.
