Spinnaker is an open-source platform designed for multi-cloud continuous delivery, enabling rapid and confident software deployment. Initially developed by Netflix, it has proven its reliability in production environments across numerous teams and millions of deployments. The platform boasts a robust pipeline management system along with seamless integrations with major cloud service providers. Users can deploy applications across a variety of cloud infrastructures such as AWS EC2, Kubernetes, Google Compute Engine, Google Kubernetes Engine, Google App Engine, Microsoft Azure, Openstack, Cloud Foundry, and Oracle Cloud Infrastructure, with support for DC/OS on the horizon. It allows for the creation of deployment pipelines that can conduct integration and system testing, manage server groups dynamically, and provide monitoring for rollout processes. Pipelines can be triggered through various events, including git actions, Jenkins, Travis CI, Docker, CRON jobs, or even other Spinnaker pipelines. Furthermore, Spinnaker enables the creation and deployment of immutable images, which can lead to quicker rollouts and simpler rollbacks, while also addressing issues related to configuration drift that are often difficult to troubleshoot. Overall, Spinnaker empowers teams to streamline their software delivery processes and embrace a more agile and efficient deployment strategy.
