在本地堆栈上自动创建S3存储桶 [英] Auto create S3 Buckets on localstack

问题描述

在我的docker-compose中使用localstack主要是模仿S3.

Using localstack in my docker-compose mainly to mimic S3.

我知道我可以创建存储桶，这不是问题.我想做的是在运行docker-compose时自动创建存储桶.

I know I can create buckets, thats not the issue. What I would like to do is automatically create the buckets when I run a docker-compose up.

已经为localstack内置了一些东西吗?

Is there something build in already for localstack?

此0.10.0版本开始> commit .

首次启动容器时，它将执行文件 在/docker-entrypoint-initaws.d中具有扩展名.sh的扩展名. 文件将按字母顺序执行.您可以轻松创建 使用以下命令中的awslocal(或aws)cli工具在本地堆栈上的aws资源 初始化脚本.

When a container is started for the first time, it will execute files with extensions .sh that are found in /docker-entrypoint-initaws.d. Files will be executed in alphabetical order. You can easily create aws resources on localstack using awslocal (or aws) cli tool in the initialization scripts.

version: '3.7'
services:
  localstack:
    image: localstack/localstack
    environment:
      - SERVICES=s3
    ports:
      - "4572:4572"
    volumes:
      - ./aws:/docker-entrypoint-initaws.d

在目录./aws/buckets.sh中具有脚本:

#!/bin/bash
set -x
awslocal s3 mb s3://bucket
set +x

注意:set [-/+] x纯粹是用于打开和关闭正在执行的命令的输出.

Note: the set [-/+] x is purely there to turn on and off outputting of the commands being executed.

将产生以下输出:

...
localstack_1  | Starting mock S3 (http port 4572)...
localstack_1  | Waiting for all LocalStack services to be ready
localstack_1  | Ready.
localstack_1  | /usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initaws.d/buckets.sh
localstack_1  | ++ awslocal s3 mb s3://bucket
localstack_1  | make_bucket: bucket
localstack_1  | ++ set +x
localstack_1  |
