docker-storj-extension

This repository contains a docker desktop extension. In the current form this is nothing more just a UI for starting a Docker Registry <-> Storj gateway.

The started container includes a modified version of distribution/distribution. It's a Docker registry which stores all the data and metadata on Storj Decentralized cloud with implementing a new Storj driver.

This extension just starts the required gateway (and explain how it can be used), but later it can be improved to use full OAuth workflow to get STORJ access grant instead of require it in the form.

The source code of the gateway can be found here and can be tested without this extension with:

docker run -p 9999:5000 -e REGISTRY_STORAGE_STORJ_BUCKET=docker -e REGISTRY_STORAGE_STORJ_ACCESSGRANT=$(cat /tmp/grant) ghcr.io/elek/distribution:618d19fb

Try it out

As the extension is not in the marketplace, you need:

• Docker Desktop: see the official documentation to install it,
• Docker Extension CLI: Download it from here and copy it to /usr/lib/docker/cli-plugins/ (or similar folder)

Extension can be installed with the command:

docker extension install ghcr.io/elek/docker-storj-extension:20220728-2

At first time, you need to create a new bucket and generate the access grant (you can use Storj web interface or uplink).

For example on EU1 gateway you can do it at https://eu1.storj.io/access-grants

After starting the container, you can use the local registry backed by Storj:

You can double check the content of the Storj bucket:

export UPLINK_ACCESS=$(cat /tmp/grant)    

uplink ls -r sj://docker/  | grep herbstag
