无法在 macOS 上启动 localstack

Question

使用 Python 3.7.10 和 pip 21.1.2

localstack 由 pip install localstack 安装。

运行命令localstack start开始，得到

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

在document上，有一个类似

的通知

(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.)

但是我再次运行这个命令：

TMPDIR=/private$TMPDIR localstack start --docker

收到此错误：

Traceback (most recent call last):
  File "/opt/code/localstack/localstack/services/plugins.py", line 102, in check_infra
    check_service_health(api=name, print_error=print_error)

在 office issue 上，有人说从环境中删除 HOSTNAME。我没设置，是不是关键原因？

为什么会出现这个 famous 问题？（而且总是？）

使用docker-compose

时输出错误

Answer 1

或者，您可以使用 docker-compose 启动 localstack。如下所示创建 docker-compose.yml 文件并使用此命令 docker-compose up 获取完美地从 localstack 开始。一旦 localstack 启动并且运行，您还可以通过点击 url 作为 http://localhost:4566/health[= 检查所有服务的健康状况12=]

先决条件：

如果您还没有安装 Docker，请安装。

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
