amazon-s3 - 在 localstack 上自动创建 S3 存储桶

Question

在我的 docker-compose 中使用 localstack 主要是为了模仿 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 up 时自动创建存储桶。

是否已经为 localstack 内置了一些东西？

自版本 0.10.0 以来，commit 中出现的更改。

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

v1.1.0 之前

version: '3.7'
services:
  localstack:
    image: localstack/localstack
    environment:
      - SERVICES=s3
    ports:
      - "4566:4566"
      # - "4572:4572" Old S3 port
    volumes:
      - ./aws:/docker-entrypoint-initaws.d

v1.1.0之后

The /docker-entrypoint-initaws.d directory usage has now been deprecated. The Pluggable initialization hooks in /etc/localstack/init/<stage>.d have replaced the legacy Init scripts, and the former will be removed entirely in the 2.0 release.

引用:localstack/localstack/issues/7257

初始化 Hook official documentation 。

version: '3.7'
services:
  localstack:
    image: localstack/localstack
    environment:
      - SERVICES=s3
    ports:
      - "4566:4566"
    volumes:
      - ./aws:/etc/localstack/init/ready.d

在 ./aws/buckets.sh 目录中使用脚本:

#!/usr/bin/env bash
awslocal s3 mb s3://bucket

将产生以下输出:

v1.1.0 之前

...
localstack_1  | Starting mock S3 (http port 4572)...
localstack_1  | Waiting for all LocalStack services to be ready
localstack_1  | Ready.

localstack_1  | make_bucket: bucket

v1.1.0之后

localstack-1  | Ready.
