This project is an emulator for several AWS services, à la Localstack. README in progress!
Currently supported services (see below for full support details):
- DynamoDB - highly experimental, only enough for Kinesis Client Library to work. Not recommended to use!
- Kinesis
- KMS
- S3
- SQS
Aws-in-a-box runs on HTTP (not HTTPS) but supports HTTP2 upgrade with h2c (HTTP without TLS).
- High-performance; no overhead from docker or proxies
- Single statically-linked 7MB native binary. No interpereter/runtime hell. (There are also 3MB compressed docker images if you prefer)
- Simple persistence scheme using atomic file writes. When using the native binary, no more broken persistent docker volumes
The easiest way to consume this project is from pre-built artifacts on the release page or the docker image. You can also build from source with either go native tooling or with Bazel, see Development section.
-addr string
Address to run on (default "localhost:4569")
-reuse-port
If set, will apply the SO_REUSEPORT socket option on Darwin/Linux platforms.
-enableKMS
Enable Kinesis service (default true)
-enableKinesis
Enable Kinesis service (default true)
-enableSQS
Enable SQS service (default true)
-enableS3
Enable S3 service (default true)
-experimental_enableDynamoDB
Enable DynamoDB service (default true)
-kinesisDefaultDuration duration
How long to retain messages. Can be used to control memory usage. After creation, retention can be adjusted with [Increase/Decrease]StreamRetentionPeriod (default 24h0m0s)
-kinesisInitialShardsPerStream int
How many shards to create for each stream listed in -kinesisInitialStreams (default 2)
-kinesisInitialStreams string
Streams to create at startup. Example: stream1,stream2,stream3
-kinesisStreamCreateDuration duration
How long a new Kinesis stream stays in CREATING status (default 5s)
-kinesisStreamDeleteDuration duration
How long a deleted Kinesis stream stays in DELETING status (default 5s)
-logLevel string
debug/info/warn/error (default "debug")
-persistDir string
Directory to persist data to. If empty, data is not persisted.
-s3InitialBuckets string
Buckets to create at startup. Example: bucket1,bucket2,bucket3
You can use either native go tooling or Bazel.
go run .bazel run //:aws-in-a-box
go test ./...bazel test //...
Most of Kinesis is implemented, including the Consumer APIS. Remaining work:
- KMS integration not wired up
- A few List/Describe APIs are missing
- Shard split/merge
There is no persistence for Kinesis data.

- Grants are missing
- Key policies are missing
KMS data is fully persisted.

Most common operations of S3 are implemented. Remaining work:
- Versioning
- A bunch of metadata/usage APIs
- Policy/ACL is missing
S3 blocks are persisted, but metadata is not. This will be fixed in the future.
