NeoFS S3 Gateway

NeoFS S3 gateway provides API compatible with Amazon S3 cloud storage service.

Installation

go get -u github.com/nspcc-dev/neofs-s3-gw

Or you can call make to build it from the cloned repository (the binary will end up in bin/neofs-s3-gw with authmate helper in bin/neofs-authmate).

Notable make targets:

dep          Check and ensure dependencies
image        Build clean docker image
dirty-image  Build dirty docker image with host-built binaries
format       Run all code formatters
lint         Run linters
version      Show current version

Or you can also use a Docker image provided for released (and occasionally unreleased) versions of gateway (:latest points to the latest stable release).

Execution

Minimalistic S3 gateway setup needs:

  • NeoFS node(s) address (S3 gateway itself is not a NeoFS node) Passed via -p parameter or via S3_GW_PEERS_<N>_ADDRESS and S3_GW_PEERS_<N>_WEIGHT environment variables (gateway supports multiple NeoFS nodes with weighted load balancing).
  • a wallet used to fetch key and communicate with NeoFS nodes Passed via --wallet parameter or S3_GW_WALLET environment variable.

These two commands are functionally equivalent, they run the gate with one backend node, some keys and otherwise default settings:

$ neofs-s3-gw -p 192.168.130.72:8080 --wallet wallet.json

$ S3_GW_PEERS_0_ADDRESS=192.168.130.72:8080 \
  S3_GW_WALLET=wallet.json \
  neofs-s3-gw

It's also possible to specify uri scheme (grpc or grpcs) when using -p or environment variables:

$ neofs-s3-gw -p grpc://192.168.130.72:8080 --wallet wallet.json

$ S3_GW_PEERS_0_ADDRESS=grpcs://192.168.130.72:8080 \
  S3_GW_WALLET=wallet.json \
  neofs-s3-gw
