If the Node hosting an instance goes down or is deleted, the Deployment controller replaces the instance with an instance on another Node in the cluster. This guide covers basic Kubernetes definitions needed to get Backstage up and Note the envFrom and secretRef - this tells Kubernetes to fill environment There are many different tools and patterns for Kubernetes clusters, so the best Since the open-source version currently does not have any end-to-end use cases, it can be challenging to understand what problems Backstage can solve for you. Our homegrown CI system uses Jenkins under the hood, but Spotify engineers dont need to know that. Deploying Backstage Backstage provides tooling to build Docker images, but can be deployed with or without Docker on many different infrastructures. Episode #136: Backstage, with Lee Mills and Matt Clarke. To get the latest news, deep dives into Backstage features, and a roundup of recent open-source action, sign up for Roadie's Backstage Weekly. But in this case, it's a lot easier to examine the ConfigMap to check for typos, since it keeps me from having to base64 decode the string. It is often sufficient to view log output This tutorial uses version 0.3.7 of the Backstage CLI to create this application. Azure DevOps Services. Now that we have a docker image for Backstage, we need somewhere to deploy it. However, it's fast and easy, which is exactly what I want out of an ephemeral database on my laptop. Use kind to create a Kubernetes cluster to work with. enter image description hereCan anyone tell how to deploy backstage on kubernetes. Use this snippet from the KIND docs. Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. NOTE: this volume also stores the configuration for PostgreSQL which includes things like the password for the Deployments can help to efficiently scale the number of replica pods, enable the rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary. This It's basically a "change in progress" as Kubernetes is transitioning a Deployment from an old state to a new state. Material-UI Theme Overrides for `withStyles` in Backstage? type of PersistentVolume. The basic workflow for this method is to build a Backstage Docker image . create a Kubernetes Service for Backstage to handle connecting requests to the It was built at Spotify and both open sourced and donated to the CNCF in 2020. Running a database on Kubernetes still hasn't quite gotten to the point that most people should do it in production, and things like CloudSQL and Amazon RDS offer extremely easy database deployments. The first time I heard about Backstage, I reacted with a resounding "huh, that's neat I guess." Backstage Kubernetes simplifies your deployment workflow by connecting to your existing Kubernetes implementation and aggregating the status of all your . Has Microsoft lowered its Windows 11 eligibility criteria? These Secret configurations used in the Postgres deployment as environment variables. For an example app-config.yaml contains various configurations of the app, database, github tokens, catalogs etc. To simplify things, you can use the app-backend plugin to serve the UI directly from the backend. Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. The final step for our database is to create the service descriptor: Apply the service to the Kubernetes cluster: Now that we have PostgreSQL up and ready to store data, we can create the Ownership information is automatically captured in our service/software catalog and users can see a list of all the services they own. everything else. dynamically. Recently, I published a recipe for Backstage, an open source project by Spotify which over the last year has witnessed tremendous adoption and growth by platform engineering teams of all types of enterprises. As before, open http://localhost:7000 in your browser to view Backstage. We've also Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). Following are the main steps of Backstage installation on Kubernets. This is done by creating . View the GKE Pod logs (Output of your python code) Prerequisites. Most of the microservices running on our cluster were using the same Kubernetes resources, such as Deployments, Services, and ConfigMaps. Make sure to create the appropriate DNS entry in your infrastructure. This documentation shows common examples that may be useful when deploying We realize this is an ambitious goal. The Pod in this tutorial has only one Container. Backstage build with Node.js and Yarn. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. We decided to release Backstage early so we could collaborate more closely with companies that have a similar problem and that want to provide a better developer experience to their teams. Services keep track of pods and direct When I started my Kubernetes journey years ago, I used manifest files to manage applications on Kubernetes. This is generally done with a Kubernetes When you create a Deployment, you'll need to specify the container image for your application and the number of replicas that you want to run. Backstage can be used in various usecases such creating a new microservice, creating CI/CD pipelines for microservices, monitoring microservices(e.g with kubernets), following a pull request from review to production, centralized technical documentation, review performance of your teams mobile features etc. We know this is running successfully because the STATUS is Running. And then add your frontend as a dependency to your backend, In order to use the plugin, you'll need to add a bit of extra code to packages/backend/src/index.ts. . Context report a problem You can create and manage a Deployment by using the Kubernetes command line interface, Kubectl. Backstage collects all of those (and more) into a single UI. Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. create a similar Kubernetes Secret as we did way to deploy to an existing Kubernetes setup is the same way you deploy In summary, Helm is a great tool for managing Kubernetes workloads, but it has its limitations, especially when it comes to maintaining charts over time. Backstage backend with scaffolder and auth plugins, Enable the issuer in the charts. The host is set with Kubernets Postgres service name(postgres), port is default Postgres port 5432. Therefore we don't want to try to connect to pods directly, but Some of the key features of Backstage include: a single-node Kubernetes cluster on your local machine: Now you can run kubectl commands and have changes applied to the minikube An alternate option would be to use -p 5432:5432 to bind port 5432 from the container to your machine. TLDR; If you're deploying a service with Kubernetes, you shouldn't have to use all of your cluster management skills just to perform everyday developer tasks (like seeing which pods are experiencing errors or checking autoscaler limits). Following is the deployment of Postgres. When deploying Backstage in an organization, we need to create Backstage app(with Nodejs npx) and keep it in a separate version controlled repository(e.g git) since the customizations need to versioned and tracked. Did you find this blog post helpful and interesting? As soon as you submit a pull request to Spotifys GitHub Enterprise, our CI system automatically posts a link to the CI/CD view in Backstage. referenced the volume created for the deployment, and given it the mount path If I'm on a team that owns observability tooling, I can write a plugin to surface that information in Backstage instead of waiting on another team to do it for me. But ultimately, most users are probably going to want to run a Backstage app, for the same reason that most users don't compile Kubernetes to deploy Kubernetes clusters. Can the Spiritual Weapon spell be used as cover? Now that you know what Deployments are, let's go to the online tutorial and deploy our first app! https://engineering.atspotify.com/2020/03/17/what-the-heck-is-backstage-anyway/, https://roadie.io/blog/backstage-docker-service-catalog/, https://raghavramesh.github.io/posts/spotify-backstage-evaluation/. cluster. the Backstage software catalog If you don't already have a cluster, create one on your laptop by installing kind and running: While the generated app contains a Dockerfile, it only containerizes the backend, and doesn't work with the app-backend plugin. Backstage has a plugin architecture, which means that the UI for different resources (components in Backstage lingo) can be owned by separate teams; In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure. If you have a specific, answerable question about how to use Kubernetes, ask it on Kubernetes has become the go-to solution for managing containerised applications, but deploying and managing applications on Kubernetes can be challenging. cluster. We need some special settings on our cluster so we can configure ingress in the cluster with Nginx. 2) Then put that Backstage software add-on as part of a cluster blueprint so that it can be a part of your default cluster set-up and provisioning. While we tried using a single Helm chart for all the services, the limitations in the Helm design meant that we had to compromise on some of the Helm features. Making statements based on opinion; back them up with references or personal experience. Partner is not responding when their writing is needed in European project application. The codebase is divided up into differentfeatures, each owned and maintained by a separate team. To test out these concepts locally before deploying to a production Kubernetes A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. Backstage is designed to fit this model and run as a stateless application with an external PostgreSQL database.
