## .env settings

### HTTP_GW_VERSION=0.15.1

pulling from DockerHub, the local image will be used.

### HTTP_GW_IMAGE=truecloudlab/frostfs-http-gw

## Usage example

- Create a new container
```
$ frostfs-cli --rpc-endpoint s01.frostfs.devenv:8080 \
            --key wallets/wallet.key \
            container create --basic-acl readonly --await \
            --policy "REP 1 SELECT 1 FROM *"
container ID: 4LfREK1cetL4PUji5fqj9SgRTSmaC5jExEDK9HKCDjdP
awaiting...
container has been persisted on sidechain

```
- Put an object into the newly created container
```
$ frostfs-cli --rpc-endpoint s01.frostfs.devenv:8080 \
            --key wallets/wallet.key \
            object put --file /tmp/backup.jpeg \
