neofs-rest-gw

NeoFS REST Gateway bridges NeoFS internal protocol and REST API server.

Installation

Building

Before building make sure you have the following tools:

• go
• make
• jq
• git
• curl

To build neofs-rest-gw call make the cloned repository (the binary will end up in bin/neofs-rest-gw).

Notable make targets:

dep             Check and ensure dependencies
image           Build clean docker image
image-dirty     Build dirty docker image with host-built binaries
formats         Run all code formatters
lint            Run linters
version         Show current version
generate-server Generate boilerplate by spec

Docker

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

REST gateway itself is not a NeoFS node, so to access NeoFS it uses node's gRPC interface and you need to provide some node that it will connect to. This can be done either via -p parameter or via REST_GW_PEERS_<N>_ADDRESS and REST_GW_PEERS_<N>_WEIGHT environment variables (the gate supports multiple NeoFS nodes with weighted load balancing).

If you're launching REST gateway in bundle with neofs-dev-env, you can get an IP address of the node in output of make hosts command (with s0*.neofs.devenv name).

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

$ neofs-rest-gw -p 192.168.130.72:8080
$ REST_GW_PEERS_0_ADDRESS=192.168.130.72:8080 neofs-rest-gw

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

$ neofs-rest-gw -p grpc://192.168.130.72:8080
$ REST_GW_PEERS_0_ADDRESS=grpcs://192.168.130.72:8080 neofs-rest-gw

Configuration

In general, everything available as CLI parameter can also be specified via environment variables, so they're not specifically mentioned in most cases (see --help also). If you prefer a config file you can use it in yaml format. See config examples for details.
