# FrostFS S3 Gateway
FrostFS S3 gateway provides API compatible with Amazon S3 cloud storage service.
## Installation
```go get -u git.frostfs.info/TrueCloudLab/frostfs-s3-gw```
Or you can call `make` to build it from the cloned repository (the binary will
end up in `bin/frostfs-s3-gw` with authmate helper in `bin/frostfs-s3-authmate`).
To build binaries in clean docker environment, call `make docker/all`.
Other 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](https://hub.docker.com/r/truecloudlab/frostfs-s3-gw) provided for released
(and occasionally unreleased) versions of gateway (`:latest` points to the
latest stable release).
## Execution
Minimalistic S3 gateway setup needs:
* FrostFS node(s) address (S3 gateway itself is not a FrostFS node)
Passed via `-p` parameter or via `S3_GW_PEERS__ADDRESS` and
`S3_GW_PEERS__WEIGHT` environment variables (gateway supports multiple
FrostFS nodes with weighted load balancing).
* a wallet used to fetch key and communicate with FrostFS nodes
Passed via `--wallet` parameter or `S3_GW_WALLET_PATH` environment variable.
These two commands are functionally equivalent, they run the gate with one
backend node, some keys and otherwise default settings:
```
$ frostfs-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 \
frostfs-s3-gw
```
It's also possible to specify uri scheme (grpc or grpcs) when using `-p` or environment variables:
```
$ frostfs-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 \
frostfs-s3-gw
```
## Domains
By default, s3-gw enable only `path-style access`.
To be able to use both: `virtual-hosted-style` and `path-style` access you must configure `listen_domains`:
```shell
$ frostfs-s3-gw -p 192.168.130.72:8080 --wallet wallet.json --listen_domains your.first.domain --listen_domains your.second.domain
```
So now you can use (e.g. `HeadBucket`. Make sure DNS is properly configured):
```shell
$ curl --head http://bucket-name.your.first.domain:8080
HTTP/1.1 200 OK
...
```
or
```shell
$ curl --head http://your.second.domain:8080/bucket-name
HTTP/1.1 200 OK
...
```
Also, you can configure domains using `.env` variables or `yaml` file.
