14 Mar spinnaker vs kubernetes

And today we’re going to talk about how Spinnaker integrates with Kubernetes. I’m the CTO of Armory. Armory’s Spinnaker distribution brings you powerful, enterprise-grade features. Matt: Lars, you’re still unmute. Matt: I don’t have numbers but certainly on the order of hundreds of VMs is a reasonable footprint to imagine. If not, roll back to my prior version. And the other part is that Kubernetes, while it does have this Deployments API, this isn’t always enough to give you a fully automated deploy from code to production. I’ve work for Google in New York with Lars, also on the Spinnaker team. It is used to configure and install Spinnaker, either locally or on a Kubernetes cluster. And over the course of those last six months, we’ve had many people come in and validate it. But in terms of the core Spinnaker features, that’s been done for about six months. In Kubernetes, an Account maps to a credential able to authenticate against your desired Kubernetes Cluster, as well as a set of Docker Registry accounts to be used as a source of images. When deploying to Kubernetes, Spinnaker will utilize Deployments, ReplicaSet, DaemonSet, etc. [It can call out to – 11:54] CI solutions like Jenkins or Travis. And that’s really where Spinnaker amplifies what you can do with Kubernetes. How does that differ from just what Spinnaker is doing? replaced. It integrates seamlessly with Jenkins and other popular build tools. Spinnaker was built to be multi-cloud, so there is a strong case for using it to deploy to cloud services like AWS and GCP but the way Kubernetes was built makes it a perfect fit for Spinnaker… Your browser has turned off or is blocking Javascript. A Spinnaker Instance maps to a Kubernetes … I am a young developer who has used spinnaker but has just jumped into helm deployments to kubernetes at my first job. Replica Set created/managed by that Deployment will compete to own the same set And Spinnaker fills the gap there by allowing you to orchestrate multiple steps by allowing you to define your deployment pipelines and say that maybe I’m going to roll out traffic to this cluster with this [to this mini pause – 03:54], check that everything is okay. already populated by Spinnaker are attached to the created Pod definition. contains a resource reference pointing to your controller, and the attach it to a Load Balancer, Spinnaker can easily enable and disable The Spinnaker Operator is used for the method of building and driving an application on top of Kubernetes. Hi, I have a small microservice application using GKE cloud and kubernetes, but right now I use my automated script for deploying the applications on my GKE cluster. So I think we can safely say that the support is very mature. following selector: This is done so that when you create a Server Group in Spinnaker, and Matt: We mostly direct focus to the Slack channels. A couple of years ago, Matt led the integration with Google, meaning that it can now deploy the Google cloud the same way that it can to Amazon. You’re not stuck to using the UI if you want to use Spinnaker. First this edits the target controller’s Pod Spec to set each label matching And recently, we’ve been adding a whole lot of other cloud providers to Spinnaker – meaning that you can deploy to Kubernetes, you can deploy to Cloud Foundry, you can deploy to Azure. But most of the initial users are larger outfits. It’s just becoming easier and cheaper. This architecture deploys well on Kubernetes because its microservices can scale independently. The account name will be the name of the Kubernetes cluster. When the Deployment What ensures that images from private registries can always be deployed. This is a combination of Enable & Disable, where the server group being rolled Lars: Sure. So there’s a Kubernetes cluster that has a bunch of YAML definitions already defined. Isaac: When you say large, I think that is another question people have, just around, okay, works for Netflix at scale. I was wondering which tool (spinnaker or helm) you guys thought is better … Key functions of Spinnaker in a Kubernetes … And once that Docker container has been validated, it’s then pushed to registry. In the VM world, that can be a Debian package. If you are using a content blocker, check to see that you have not globally turned off Javascript. being rolled back from is disabled. This invokes the delete operation on the given Pod. More like Infrastructure as Code, I think, is what people usually say. I’m Lars. Passing along our understanding of enterprise-scale software delivery to new DevOps practitioners keeps us in touch with the Armory […], https://www.linkedin.com/in/lars-wander-82697897, Read all posts related to Spinnaker + Kubernetes, Armory Spinnaker Release v0.61Armory Spinnaker Release Version 0.61: Free Distribution That Anyone Can Install and is Guaranteed to Work, Originally developed by Netflix, recently open-sourced, Natively supports Google Cloud along with AWS and other cloud providers, Support was also added for Kubernetes, Azure, Cloudfoundry, Spinnaker offers deployment pipelines and also allows for easy rollbacks, Spinnaker and Kubernetes work very well together, Spinnaker can show the health of a Kubernetes cluster. Resource mapping between Spinnaker and Kubernetes constructs, as well as theintroduction of new types of resources, is a lot more flexible in theKubernetes provider V2 than for other providers, because of how many types ofresources Kubernetes supports. And then you can use that deployed object either as a template for future deployments, or you can go ahead and make edits to those YAML files within the Spinnaker UI by effectively cloning a server group and saying, “I want to redeploy this but with these attributes changed.” And you can do that with a deployment strategy as well. operation. Deployments and Replica Sets share the same set of label-selectors, every Hopefully, this clears up a lot of questions. Lars: Yeah, sure. In this tutorial, I will walk you through how to setup and configure Spinnaker … There are definitely several users we have that are one- and two-person shops. Spinnaker offers a ton of options for Kubernetes deployments. Or what other ways can I modify the YAML file that are there in the pipeline [… – 10:32]? As marketed, Spinnaker is an open-source, multi-cloud continuous delivery platform that helps you release software changes with high velocity and confidence. Lars: If you have something already deployed in a Kubernetes cluster and you point Spinnaker at it, Spinnaker will go ahead and cache everything in there and represent it as if it had been deployed by Spinnaker in the first place. resources. There are two things to take note of here: The labeling scheme is a little more complex when Deployment objects are documentation. And a lot of that is showing you what you have running, what’s eating traffic, what’s healthy. Image Pull Kubernetes Networking – An Implementer’s In-depth Guide. I’m sure there are a lot of people who are using GK, GCP, who are interested in using Spinnaker and seeing how it fits [… – 16:10]. Learn how to leverage Spinnaker for OPA Policy Deployment, and how to leverage OPA Policies to govern spinnaker. You can either consume manifests from GCS or S3 bucket or you can provide manifest as text within the pipeline. There are other large companies like the Openstack integration [apps – 15:17] that’s targeted Veritas [4K – 15:19]. So that seems to be fairly common that there are folks [dedicated to – 15:40] operating it, and then they make that available to the other engineers [… – 15:43]. Netflix open sourced it in 2015. I think most of the larger companies have several folks that are dedicated to running the Spinnaker deployment itself, and any individual development teams have access to that [… – 15:36]. controller, (e.g. Not configuration management tool. Does it replace it? does exist, does the same, but edits the Deployment in place rather than This operates the same as Deploy; however, the properties the server group And obviously, the next step is how do I automate deployments into Kubernetes. back to is first enabled, and once all health checks pass, the server group We have like a growing set of solutions docks and tutorials and code labs and things like that. So that works just as one might expect. It’s very similar to the model that independently Kubernetes has come up with. In fact, Spinnaker really doesn’t add any extra metadata on top of any of your cloud providers or deployment environments, aside for things like the deployment strategies used to roll out infrastructure to those deployment environments. Spinnaker … How does Spinnaker fit with Kubernetes and what does that look like? So how mature is support for Kubernetes within Spinnaker as of today? You can easily use the Kubernetes tools to help you solve the … Spinnaker use Deployments and Clusters respectively to represent versioned, import existing deployed applications into Spinnaker, and would prefer to Going back a bit, when we first wrote support for Kubernetes and Spinnaker, the Deployment object wasn’t so much at the forefront. And there seem to be a lot of questions around Kubernetes and Spinnaker and how they work together. How does Spinnaker handle those configuration files? Spinnaker needs access to your Kubernetes manifests in order to deploy them to your clusters. And as we make progress on that, it makes it that you don’t need quite as much skill to justify the amount of work and expense to run Spinnaker. cloned, and those specified in the operation, preferring those specified in the above, adds the necessary ImagePullSecrets for your desired docker This enumerates the various “Atomic Operations” and how they modify Kubernetes In the end, however, both providers are limited by the fact that Spinnaker is a generic multi-cloud deployment tool and Kubernetes support was “shoehorned” in as Kubernetes is … And each of those platforms has a pretty sizable team working on that support. ${DOCKER-REGISTRY}, the following will appear in the Pod template: A Spinnaker Cluster can optionally map to a Kubernetes Spinnaker is an open-source, multi-cloud continuous delivery platform that helps you release software changes with high velocity and confidence.Open sourced by Netflix and heavily contributed to by Google, it supports all major cloud vendors (AWS, Azure, App Engine, Openstack, etc.) For Kubernetes, that’s obviously a Docker container. Pod. Deletes the service - this will not edit any pods associated with the service. After your manifests are in Cloud Storage, Spinnaker … controller you are modifying. exist, Spinnaker first creates the Replica Set with replicas: 0, and then Spinnaker vs… So what that means for you is that if you have some Kubernetes YAML files that you want to deploy to a cluster that’s being managed by Spinnaker and you do that deployment, it’ll show up in a cluster as though Spinnaker had done it. Seeking 2021 Google Summer of Code Interns, Engineer With Armory, Sponsored by Google Armory is proud to invest in Google Summer of Code again this year, and help foster a new generation of global engineering talent by mentoring students in CD Foundation projects. Creates a Kubernetes service with labels matching those shown If you are not familiar with Kubernetes or some of the Kubernetes terminology So if I were to point Spinnaker at a cluster, I would see everything running there as if Spinnaker had deployed it. Get monthly updates, unsubscribe anytime. And Spinnaker makes all this very foolproof. I think they fit together very well for two reasons. involved, because Kubernetes deployments find Pods to manage using Not only is the Kubernetes … And if something goes wrong there, it could be an error in the script, it could be an error in your deployment policy. Therefore, the labeling Cloud Provider’s infrastructure. In the previous installment of the series, we introduced Spinnaker as the multicloud deployment tool. Isaac: Right. When Spinnaker creates a service with name ${LOAD-BALANCER}, it sets the used below, please read the reference A fully-managed instance of Armory, installed in your cloud. Open sourced by Netflix and heavily contributed to by Google, it supports all major cloud vendors (AWS, Azure, App Engine, Openstack, etc.) Consuming … And Jenkins is great for running arbitrary scripts and passing data between those scripts. Debugging Jenkins plus the glue code is a big challenge, Kubernetes support in Spinnaker is feature complete, Customers are already using Spinnaker to deploy to production Kubernetes clusters, Tweaks and performance improvements are an ongoing process, Originally Kubernetes used the deployment controller, Now the suggested deployment construct is the replica set, Spinnaker is using the official Kubernetes API so it can do everything that Kubernetes is capable of doing on its own (i.e. You can deploy Spinnaker in a number of different environments, including on OpenStack and on your local machine, but for the sake of simplicity (and because a local deployment of Spinnaker is a bit of a hefty beast) we’re going to do a distributed deployment on a Kubernetes … Isaac: That’s the majority of the questions we see around Kubernetes and Spinnaker, so thank you for that. All right, guys, thanks. And I guess why wouldn’t I want to do this myself or what other tools are there for me to do this on my own? And at any point in time, when you have a pipeline definition which describes how you make changes to your cloud environment, you can click Use JSON in the pipeline editor and you’ll see exactly what’s going on behind the scenes so to speak. Spinnaker will use an Auto Scaling Group (ASG) to provision machines on AWS or the equivalent on GCP, Azure, OCI, etc. The Spinnaker Operator is a Kubernetes Operator for managing Spinnaker, built by Armory and available for free. Lars: Spinnaker really doesn’t want to become a CI solution. Deployment. We know there are customers using it to deploy to production. (vNNN) ${SEQUENCE-NUMBER}, and active server group Isaac: Another thing that frequently comes up is around the [… 08:11] deployments and YAML file. Spinnaker is automatically exposed with Kubernetes service load balancers (optional). delete the Deployment as well. So if you want to rely on Kubernetes’ underlying deployment mechanisms inside Spinnaker, it’s totally fine. And I know you’ve answered some of that. I did the bulk of the GC integration and a bunch of stuff and the core components of Spinnaker and have been working with the Netflix guys and some other folks on the Spinnaker project since close to the beginning of the project. Typically, in Spinnaker, Clusters are a logical grouping, not backed by a So there are a number of folks who are competent and experienced enough to help [… – 13:32]. Matt: I’m here for mostly emotional support. With spinnaker in the mix, you are guaranteed to have a safe deployment every time. here. How does it work with it? well as a set of Docker Registry accounts Argo is an open source container-native workflow engine for getting work done on Kubernetes. The Kubernetes provider relies on annotations on Kubernetes resources to drive functionality. After setting up storage for Spinnaker, we will add Kubernetes cluster(s) as cloud-provider(s). SERVER-GROUP-NAME=${CLUSTER-NAME}-v${SEQUENCE-NUMBER} looks like this: Meanwhile, to circumvent Kubernetes’ naming of Replica Sets and impose Argo CD is a declarative, GitOps continuous … traffic to individual pods by editing their labels like so: As seen above, this is how Spinnaker supports an M:N relationship
