Proposal: S3 Backend

Description

Implement an S3 backend so that we can store the state file in S3.

Assumptions

• Use aws-sdk-go-v2 for interactions with AWS apis.
• Credentials stored in `~/.aws/credentials
• Use mocks for unit testing.

Design

S3Backend

type S3Backend struct {
    file *S3File
}

func NewS3Backend(bucket, region, key string) *S3Backend

func (b *S3Backend) Read() (byte[], error)

func (b *S3Backend) Write(data byte[]) error

S3File

type S3File struct {
    Bucket string
    Region string
    Key string
    ctx context.Context
    client *s3.Client
}

func NewS3File(ctx context.Context, bucket, region, key string, client *s3.Client) (*S3File, error)

func (f *S3File) Put(data []byte) error

func (f *S3File) Download() ([]byte error)
