Spinnaker 1.0: a continuous delivery
platform for cloud
June 7, 2017
At Google we deploy a lot of
code: tens of thousands of deployments a day, to thousands of
services, seven of which have more than a billion users each around
the globe. Along the way we’ve learned some best practices about how
to deploy software at velocity — things
like automated releases, immutable infrastructure, gradual rollouts
and fast rollbacks.
Why Spinnaker?Let’s look at a few of the features and new updates that can make Spinnaker a great release management solution for enterprises:
Open-source, multi-cloud deployments
Here at Google Cloud Platform (GCP), we believe in an open cloud. Spinnaker, including its rich UI dashboard, is 100% open-source. You can install it locally, on-prem, or in the cloud, running either on a virtual machine (VM) or Kubernetes.
Spinnaker streamlines the deployment process by decoupling your release pipeline from your target cloud provider, which can reduce the complexity of moving from one platform to another or deploying the same application to multiple clouds.
It has built-in support for Google Compute Engine, Google Container Engine, Google App Engine, AWS EC2, Microsoft Azure, Kubernetes, and OpenStack, with more added every year by the community, including Oracle Bare Metal and DC/OS, coming soon.
Whether you’re releasing to multiple clouds or preventing vendor lock-in, Spinnaker helps you deploy your application based on what’s best for your business.
In Spinnaker, deployments are orchestrated using custom release pipelines, the stages of which can consist of almost anything you want -- integration or system tests, spinning a server group up or down, manual approvals, waiting a period of time, or running a custom script or Jenkins job.
Spinnaker integrates seamlessly with your existing continuous integration (CI) workflows. You can trigger pipelines from git, Jenkins, Travis CI, Docker registries, on a cron-like schedule, or even other pipelines.
Best-practice deployment strategies
Out-of-the-box, Spinnaker supports sophisticated deployment strategies like release canaries, multiple staging environments, red/black (a.k.a. blue/green) deployments, traffic splitting and easy rollbacks.
This is enabled in part by Spinnaker’s use of immutable infrastructure in the cloud, where changes to your application trigger a redeployment of your entire server fleet. Compare this to the traditional approach of configuring updates to running machines, which results in slower, riskier rollouts and hard-to-debug configuration-drift issues.
With Spinnaker, you simply choose the deployment strategy you want to use for each environment, e.g. red/black for staging, rolling red/black for production, and it orchestrates the dozens of steps necessary under-the-hood. You don’t have to write your own deployment tool or maintain a complex web of Jenkins scripts to have enterprise-grade rollouts.
Role-based authorizations and permissions
Large companies often adopt Spinnaker across multiple product areas managed by a central DevOps team. For admins that need role-based access control for a project or account, Spinnaker supports multiple authentication and authorization options, including OAuth, SAML, LDAP, X.509 certs, GitHub teams, Azure groups or Google Groups.
You can also apply permissions to manual judgements, a Spinnaker stage which requires a person’s approval before proceeding with the pipeline, ensuring that a release can’t happen without the right people signing off.
Simplified installation and management with halyard
With the release of Spinnaker 1.0, we’re also announcing the launch of a new CLI tool, halyard, that helps admins more easily install, configure and upgrade a production-ready instance of Spinnaker.
Prior to halyard and Spinnaker 1.0, admins had to manage each of the microservices that make up Spinnaker individually. Starting with 1.0, all new Spinnaker releases are individually versioned and follow semantic versioning. With halyard, upgrading to the latest Spinnaker release is as simple as running a CLI command.
