Can't start localstack on macOS

Using Python 3.7.10 and pip 21.1.2

Installed localstack by pip install localstack.

Ran command localstack start to start, got

WARNING:localstack.services.plugins: Service "s3" not yet available, retrying...

On the document, there is a notice like

(Note that on MacOS you may have to run TMPDIR=/private$TMPDIR localstack start --docker if $TMPDIR contains a symbolic link that cannot be mounted by Docker.)

But I ran this command again:

TMPDIR=/private$TMPDIR localstack start --docker

got this error:

Traceback (most recent call last):

On the office issue, somebody said remove HOSTNAME from environment. I didn't set it, is it the key reason?

Why this famous issue happened? (And always?)

output errors when use docker-compose

Alternatively, You can start localstack using docker-compose. Create docker-compose.yml file as given below and use this command docker-compose up to get started with localstack perfectly. Once localstack is up and running, you can also check the health of all the services by hitting url as http://localhost:4566/health

Prerequisites:

  • Have Docker installed, if you haven’t already.
version: "3.8"
services:
  localstack:
    container_name: "${LOCALSTACK_DOCKER_NAME-localstack}"
    image: localstack/localstack
    hostname: localstack
    networks:
      - test-net
    ports:
      - "4566:4566"
    environment:
      - SERVICES=s3,sqs,cloudformation,iam,cloudwatch
      - DEBUG=1
      - DATA_DIR=/tmp/localstack/data
      - LAMBDA_EXECUTOR=docker-reuse
      - LAMBDA_REMOTE_DOCKER=false
      - LAMBDA_REMOVE_CONTAINERS=true
      - DOCKER_HOST=unix:///var/run/docker.sock
      - HOST_TMP_FOLDER=${TMPDIR}
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
networks:
  test-net:
    external: false
    driver: bridge
    name: test-net
