GitHub Workflow Status Coveralls GitHub repo size

Sigma is an image registry that is extremely easy to deploy and maintain, and it adheres to the interface standards defined by the OCI Distribution Specification 1.1, it can also support any other client programs that follow the interface definition of the OCI Distribution Specification, such as oras, apptainer, helm, and nerdctl.

Quick Start

Now you can use this command to run a simple server:

docker run --name sigma -p 3000:3000 --rm tosone/sigma:nightly-alpine

The default username is sigma. The password is generated randomly on first start and printed in the server logs, so check the logs after the first startup. If you want to use a fixed password, set auth.admin.password by following the configuration instructions.

Demo Server

It is deployed on an AWS EC2 instance (2C4G, 40G disk) running Debian 12.1 as the Linux distribution. The Docker version used is 25.0.3. The demo server was set up following these instructions.

AI Clients and Automation

Sigma provides two integration paths for AI clients and external automation:

  • sigma-cli: a single binary that operates a remote Sigma server over the REST API. It covers namespaces, repositories, tags, artifacts, members, and users. See CLI & AI Agents.
  • External REST API skill: tools/skill/sigma-api-operator packages a reusable skill and swagger.yaml so CLI agents such as Claude Code or Copilot CLI can discover Sigma APIs and operate resources through HTTP requests, including the areas the CLI does not wrap yet.
