A Docker control panel based on Docker Swarm with enterprise features like private registry authentication, ACL, and application bundle sharing.
Crane is a Docker control panel built on Docker Swarm that provides a web-based interface for managing containerized applications. It extends native Swarm features with enterprise functionalities like private registry authentication, access control lists (ACL), and distributed application bundle (DAB) sharing. The project solves the problem of managing Docker Swarm clusters in team environments where secure image sharing and reusable deployment templates are needed.
DevOps engineers and development teams using Docker Swarm for container orchestration who need enhanced management capabilities beyond the default Swarm toolkit. It's particularly useful for enterprises requiring private registry integration and collaborative application deployment.
Developers choose Crane because it adds critical enterprise features to Docker Swarm through an intuitive interface, eliminating the need for manual credential management and enabling easy sharing of application stacks. Its fuzzy search and detailed node operations provide better visibility and control compared to native Swarm tools.

Provides a web-based portal for nearly all Docker Swarm features, improving usability over command-line tools as highlighted in the README's 'Swarm features' section.
Allows saving running stacks as templates for repeated deployment, facilitating consistency and collaboration within teams, as described under 'Stack Templates Management'.
Manages authentication for private registries, enabling deployment of stacks with restricted images without manual docker login, a key enterprise feature noted in the features list.
Includes a WebSSH interface powered by docker exec, allowing direct command execution in containers through the browser for quick troubleshooting.
Requires enabling Docker's TCP socket on port 2375, which can be a security vulnerability if not properly secured, as acknowledged in the prerequisites with a link to configuration docs.
Only officially supports older OS versions like Ubuntu 12.04/14.04 and CentOS 7.X, which may not align with modern infrastructure standards, as listed under 'OS supported'.
Exclusively tied to Docker Swarm, making it irrelevant for projects using alternative orchestration platforms like Kubernetes, limiting its applicability beyond Swarm ecosystems.
