localstack Kinesis 无法在 docker 中启动

Question

我们在 Windows 10 上运行 Docker。我们有一个简单的 Java Springboot 应用程序，它应该与 AWS Kinesis 和 S3 交互。对于本地测试，我们想要拉取 localstack Docker 最新镜像并安装并运行。但是 Kinesis 的启动会抛出错误，而 S3 则工作正常。以下是详细信息：

docker compose:
version: '3.1'
services:
  localstack:
    image: "localstack/localstack"
    container_name: localstack_demo
    environment:
      SERVICES: kinesis, s3, sqs
      DEBUG: 1
      DATA_DIR: /tmp/localstack
      KINESIS_STREAM_SHARDS: 1
      KINESIS_ERROR_PROBABILITY: 0.0
      KINESIS_STREAM_NAME: my-stream
    ports:
      - "4567-4584:4567-4584"
      - "8055:8080"
    volumes:
      - './.localstack:/tmp/localstack'
      - '/var/run/docker.sock:/var/run/docker.sock'

当我们尝试访问 Kinesis 的默认 URL 时http://localhost:4568，我们收到以下错误：（请注意，S3 的默认 URL 按预期响应）：

localstack_demo | 2019-09-24T22:35:27:ERROR:localstack.services.generic_proxy: Error forwarding request: the JSON object must be str, bytes or bytearray, not 'NoneType' Traceback (most recent call last):
localstack_demo |   File "/opt/code/localstack/localstack/services/generic_proxy.py", line 240, in forward
localstack_demo |     path=path, data=data, headers=forward_headers)
localstack_demo |   File "/opt/code/localstack/localstack/services/kinesis/kinesis_listener.py", line 22, in forward_request
localstack_demo |     data = json.loads(to_str(data))
localstack_demo |   File "/usr/lib/python3.6/json/__init__.py", line 348, in loads
localstack_demo |     'not {!r}'.format(s.__class__.__name__))
localstack_demo | TypeError: the JSON object must be str, bytes or bytearray, not 'NoneType'

我的码头安装：

我认为这可能是您格式化 docker compose YAML 文件的方式，这里是您想要实现的目标的可能修复方法：

version: '3.1'
services:
  localstack:
    image: "localstack/localstack"
    container_name: localstack_demo
    environment:
      - SERVICES=kinesis,s3,sqs
      - DEBUG=1
      - DATA_DIR=/tmp/localstack
      - KINESIS_STREAM_SHARDS=1
      - KINESIS_ERROR_PROBABILITY=0.0
      - KINESIS_STREAM_NAME=my-stream
    ports:
      - "4567-4584:4567-4584"
      - "8055:8080"
    volumes:
      - './.localstack:/tmp/localstack'
      - '/var/run/docker.sock:/var/run/docker.sock'

希望这可以帮助

Answer 2

所以，我试图验证（提供强有力的证据）答案，但显然默认的运动提供程序在我的 Silicon M1 上无法正常工作（如果你明白我的意思）。我注意到默认的 kinesis 提供程序kinesis-mock在启动后立即崩溃......

对我有用的解决方案是使用环境变量切换 kinesis 提供程序：

- KINESIS_PROVIDER=kinesalite

配置可能与之前的答案类似，但添加了以下内容：

version: '3.1'
services:
  localstack:
    image: "localstack/localstack"
    container_name: localstack_demo
    environment:
      - SERVICES=kinesis,s3,sqs
      - DEBUG=1
      - DATA_DIR=/tmp/localstack
      - KINESIS_STREAM_SHARDS=1
      - KINESIS_ERROR_PROBABILITY=0.0
      - KINESIS_STREAM_NAME=my-stream
      - KINESIS_PROVIDER=kinesalite
    ports:
      - "4567-4584:4567-4584"
      - "8055:8080"
    volumes:
      - './.localstack:/tmp/localstack'
      - '/var/run/docker.sock:/var/run/docker.sock'

希望有帮助
