Creating DynamodDB table on start of the localstack

问题

使用Localstack与DynamoDB，并需要在启动时默认创建一些表格。然而，我遇到了一个奇怪的错误：

  1. /docker-entrypoint-initaws.d/init.sh: is a directory

docker-compose配置：

  1. localstack:
  2.     container_name: localstack
  3.     image: localstack/localstack:latest
  4.     network_mode: bridge
  5.     ports:
  6.       - "4566:4566"
  7.       - "8010:8010"
  8.     environment:
  9.       - EDGE_PORT=8010
  10.       - SERVICES=s3,dynamodb
  11.       - DEBUG=1
  12.       - DATA_DIR=/tmp/localstack/data
  13.     volumes:
  14.       - "$PWD/.localstack/init.sh:/docker-entrypoint-initaws.d/init.sh"

而 init.sh 文件如下：

  1. awslocal dynamodb create-table \
  2.    --table-name table-global \
  3.    --attribute-definitions AttributeName=id,AttributeType=S \
  4.    --key-schema AttributeName=id,KeyType=HASH \
  5.    --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

我的环境：

  • 操作系统：MacOS Ventura
  • Docker 版本：v4.16.2

我尝试了多种选项，但仍然无法解决问题。我不确定我可能做错了什么。

Using Localstack with Dynamodb and need to create some tables by default on the start. However, I am getting the strange error that:

  1. /docker-entrypoint-initaws.d/init.sh: is a directory

docker-compose config:

  1. localstack:
  2.     container_name: localstack
  3.     image: localstack/localstack:latest
  4.     network_mode: bridge
  5.     ports:
  6.       - "4566:4566"
  7.       - "8010:8010"
  8.     environment:
  9.       - EDGE_PORT=8010
  10.       - SERVICES=s3,dynamodb
  11.       - DEBUG=1
  12.       - DATA_DIR=/tmp/localstack/data
  13.     volumes:
  14.       - "$PWD/.localstack/init.sh:/docker-entrypoint-initaws.d/init.sh"

and the init.sh looks like:

  1. awslocal dynamodb create-table \
  2.    --table-name table-global \
  3.    --attribute-definitions AttributeName=id,AttributeType=S \
  4.    --key-schema AttributeName=id,KeyType=HASH \
  5.    --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

My stack:

  • OS: MacOS Ventura
  • Docker: v4.16.2

I have tried multiple options but it still does not work. I am not sure what I might be doing wrong.

我通过更改您的 docker-compose.yml 文件来修复了您的问题：

  1. version: "3.8"
  3. services:
  4.   localstack:
  5.     container_name: "${LOCALSTACK_DOCKER_NAME-localstack_main}"
  6.     image: localstack/localstack
  7.     ports:
  8.       - "127.0.0.1:4566:4566"
  9.     environment:
  10.       - DEBUG=1
  11.       - DOCKER_HOST=unix:///var/run/docker.sock
  12.     volumes:
  13.       - "$PWD/init-aws.sh:/etc/localstack/init/ready.d/init-aws.sh"  # ready hook
  14.       - "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
  15.       - "/var/run/docker.sock:/var/run/docker.sock"

init-aws.sh 文件如下：

  1. #!/bin/bash
  2. awslocal dynamodb create-table \
  3.    --table-name table-global \
  4.    --attribute-definitions AttributeName=id,AttributeType=S \
  5.    --key-schema AttributeName=id,KeyType=HASH \
  6.    --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

请确保首先对文件运行 chmod +x init-aws.sh。

您可以通过以下命令验证此操作：

  1. $ awslocal dynamodb list-tables
  2. {
  3.     "TableNames": [
  4.         "table-global"
  5.     ]
  6. }
英文:

I fixed your issue by changing your docker-compose.yml to:

  1. version: "3.8"
  3. services:
  4.   localstack:
  5.     container_name: "${LOCALSTACK_DOCKER_NAME-localstack_main}"
  6.     image: localstack/localstack
  7.     ports:
  8.       - "127.0.0.1:4566:4566"
  9.     environment:
  10.       - DEBUG=1
  11.       - DOCKER_HOST=unix:///var/run/docker.sock
  12.     volumes:
  13.       - "$PWD/init-aws.sh:/etc/localstack/init/ready.d/init-aws.sh"  # ready hook
  14.       - "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
  15.       - "/var/run/docker.sock:/var/run/docker.sock"

The init-aws.sh looks like:

  1. #!/bin/bash
  2. awslocal dynamodb create-table \
  3.    --table-name table-global \
  4.    --attribute-definitions AttributeName=id,AttributeType=S \
  5.    --key-schema AttributeName=id,KeyType=HASH \
  6.    --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5

Make sure to run chmod +x init-aws.sh on the file first.

I can validate this via the following command:

  1. $ awslocal dynamodb list-tables
  2. {
  3.     "TableNames": [
  4.         "table-global"
  5.     ]
  6. }
