Software Content Management

Spacewalk manages software content updates for Red Hat derived distributions such as Fedora, CentOS, and Scientific Linux, within your firewall. You can stage software content through different environments, managing the deployment of updates to systems and allowing you to view at which update level any given system is at across your deployment. A central web interface allows viewing of systems, their associated software update status, and initiating update actions.

Additional Management Capabilities

Spacewalk also provides provisioning capabilities, allowing you to manage your systems throughout their lifecycle. Via Provisioning, Spacewalk enables you to kickstart provision systems and manage and deploy configuration files. Spacewalk also has virtualization capabilities to enable you to provision, control, manage, and monitor virtual KVM and Xen guests.

Providing Content to Geographically-Distributed Systems

Part of the Spacewalk project is the Spacewalk Proxy, the upstream of the Red Hat Satellite Proxy product. Multiple Spacewalk Proxies can connect to a central Spacewalk server and cache and distribute content from the Spacewalk Server in various geographical locations, reducing the load on the central server and improving download times for local systems.

An Open Community Project

Spacewalk is an open community project. Anyone can contribute to the project, including lending a hand with ideas, feedback, contributing a patch, helping draft documentation, sharing your systems management use cases, or even testing. Sign up for our mailing list or join our IRC channel and say hello!
