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.. You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. Ownership information is automatically captured in our service/software catalog and users can see a list of all the services they own. The Postgres storage deployed with persistent volume. It also allows the creation of new resources, such as backend services running in Kubernetes, with a few clicks of a button all without having to leave the same, familiar interface of Backstage. Kubernetes will automatically pick Docker as the default container runtime. It was built at Spotify and both open sourced and donated to the CNCF in 2020. Spotify uses adocs-like-codeapproach. Be sure to enable Similar to how Backstage ties together all of Spotifys infrastructure, our ambition is to make the open-source version of Backstage the standard UX layer across the broader infrastructure landscape. Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. But if youdig deeper, youll find that since the very beginning, Spotify has been known for its agile, autonomous engineering culture. Asking for help, clarification, or responding to other answers. Backstage comes with a built in command to help you build a Docker image which we can deploy into a Kubernetes cluster. So, in the spirit of too much free time on a Saturday, I decided to try to deploy a Backstage app to Kubernetes, Now that the image is loaded, we can create a Backstage deployment and a service to expose it on an IP inside the cluster. In essence, Backstage tries to solve the problem of discoverability for developer resources. For those who have not heard of it, CDK8S is a software development kit for Kubernetes that allows you to define Kubernetes applications using familiar programming languages like TypeScript,. There is also an example of deploying on Heroku, which only If you do this in production, it'll gain you a well-earned Slack message from your closest Security contact that says "we need to talk." Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. A Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. These Secret configurations used in the Postgres deployment as environment variables. Make sure to create the appropriate DNS entry in your infrastructure. If you run into 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. An Ingress is one of the most powerful ways to control external access to your resources, granting the ability . The solution is to make sure that the contents of the configMap that holds the certificate match the CA for the PostgreSQL instance. Our mobile apps are developed by many different teams. This is most of the way to a full production deployment of Backstage on 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. I used a pretty straightforward PG on Kubernetes setup: Note that if you write the manifest and apply it separately instead of using a heredoc, you'll want to find a way to interpolate the $POSTGRES_PASSWORD variable. This tutorial uses version 0.3.7 of the Backstage CLI to create this application. An overview by Roadie. For your first Deployment, you'll use a hello-node application packaged in a Docker container that uses NGINX to echo back all the requests. the minikube internal Docker registry and then rebuild the image to install A Kubernetes plugin was recently added. The deployment and pod are running in the cluster. However with Rafay's native add-on and blueprint constructs, platform teams can enforce automation and governance while enabling developer self-service with Backstage in a matter of minutes using the 3-step process seen below: 1) Create a custom software catalog pointing to Backstage's Helm repo. Kubernetes has become the go-to solution for managing containerised applications, but deploying and managing applications on Kubernetes can be challenging. the default HTTP port 80): If you're using an auth provider, it should also have this The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. Therefore we don't want to try to connect to pods directly, but A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. This is done by creating . with the given pod template, which again contains Kubernetes metadata and a Kubernetes command-line tool. Kubectl uses the Kubernetes API to interact with the cluster. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? plugins available for GitHub Actions, ArgoCD, AWS, and more), ability to easily build and publish tech documentation, native Kubernetes plugin for cloud-native apps, ability to compose different developer workflows into an Internal Developer Portal (IDP). The Backstage app run with separate Kubernetes namespace. However, over the past few weeks it's come up in conversation with engineers whose opinions I respect, Episode #136: Backstage, with Lee Mills and Matt Clarke. We know this is running successfully because the STATUS is Running. Finally, we can deploy Backstage to Kubernetes. Why did the Soviets not shoot down US spy satellites during the Cold War? Kubernetes node is spending 5 minutes pulling the image and you're trying to without Docker on many different infrastructures. Our internal installation of Backstage has over 100 different integrations we call them plugins. You can use Azure Pipelines to deploy to Azure Kubernetes Service and Kubernetes clusters offered by other cloud providers. As before, open http://localhost:7000 in your browser to view Backstage. Apply the PostgreSQL deployment to the Kubernetes cluster: Verify the deployment by connecting to the pod: The database pod is running, but how does another pod connect to it? First create a yaml file with the configuration you want to override, for example backstage-prod.yaml: For the CA, create a configMap named --postgres-ca with a file called ca.crt: Where the release name contains the chart name "backstage" then only the release name will be used. This follows similar steps as the PostgreSQL deployment. Everything connected with Tech & Code. You probably want to use a database outside of Kubernetes. Find centralized, trusted content and collaborate around the technologies you use most. Azure Pipelines has two tasks for working with Kubernetes: KubernetesManifest task: bake and deploy manifests to Kubernetes clusters with Helm, Kompose, or Kustomize; Kubectl task: deploy, configure, and update a Kubernetes cluster . You'll want to create a separate database user for Backstage. We created Backstage about four years ago. On top of the static documentation we also incorporate additional metadata about the documentation site such as owner, open issue and related Stack Overflow tags. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. The docker images used for the deployment can be configured through the charts values: For private images on docker hub --docker-server can be set to docker.io, Reference the secret in your chart values. Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. This guide covers basic Kubernetes definitions needed to get Backstage up and for PostgreSQL, remembering to base64 encode expected by PostgreSQL. postgres user. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. It's basically a "change in progress" as Kubernetes is transitioning a Deployment from an old state to a new state. Visit me @ www.asimayub.com. Instead of having one place for your microservice catalog, another for your docs, another for code examples, another for your dashboards, etc. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. Save the following YAML into a file called manifest.yaml. Backstage requires a database to store information about the components, websites and other entities you want to track in the catalog. Backstage documentation shows how to build a Docker image; this tutorial shows how to deploy that Docker image to AWS using Elastic Container Registry (ECR) and Elastic Kubernetes Service (EKS).Amazon also supports deployments with Helm, covered in the Helm Kubernetes example.. What's the difference between a power rail and a signal line? A Kubernetes Pod is a group of one or more Containers, tied together for the purposes of administration and networking. If you're reading this a year from now, first, congrats on making it out of 2020, and second, go with what the docs say. a PersistentVolumeClaim. Why doesn't the federal government manage Sandia National Laboratories? Hence, I prefer Pulumi over Terraform and CDK8S over Helm. This cluster has no network access and thus, without setting imagePullPolicy: Never, our deployment would fail. The Linux Foundation has registered trademarks and uses trademarks. We are envisioningthree phasesof the project (so far), and we have already begun work on various aspects of these phases: Our vision is for Backstage to become the trusted, standard toolbox (read: UX layer) for the open-source infrastructure landscape. any trouble, check the container logs from the pod: Like the PostgreSQL service above, we need to 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). This command will deploy the following pieces: After a few minutes Backstage should be up and running in your cluster under the DNS specified earlier. It looks like nothing has changed, but this page is being rendered inside our Kubernetes cluster and exposed to the browser. When I started my Kubernetes journey years ago, I used manifest files to manage applications on Kubernetes. The backstage Docker image we built previously is not automatically shared with our KIND kubernetes cluster. The Kubescape extension works by installing the Kubescape in-cluster components, connecting them to the ARMO platform and providing insights into the Kubernetes cluster deployed by Docker Desktop via the dashboard on the ARMO platform. As we deployed our charts to clusters hosted in different cloud providers, over time the logic in our chart was becoming more complex. browse your Kubernetes-deployed Backstage instance. This could be things like logging or monitoring agents. Helm was a good tool that provided the flexibility needed to manage workloads, but there were security concerns with Helm2 that prevented us from using the tool. The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. Backstage is designed to fit this model and run as a stateless application with an external PostgreSQL database. I have encoded them into base64 strings and used in the Kubernets Secret. This should be replaced with a cloud volume, network attached storage, or We need some special settings on our cluster so we can configure ingress in the cluster with Nginx. Has Microsoft lowered its Windows 11 eligibility criteria? Apply the storage volume and claim to the Kubernetes cluster: Now we can create a Kubernetes Deployment descriptor for the PostgreSQL database Once the application instances are created, a Kubernetes Deployment Controller continuously monitors those instances. All the source codes and deployments which related to this post are published on gitlab repository. 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 create a similar Kubernetes Secret as we did pod port. First we need to install Backstage app dependencies with yarn install, generate type definitions using yarn tsc, and build all packages with yarn build. Or paste the errors as well, Added now in the question can you please check it. One frontend for all your infrastructure. rather create a Kubernetes Service. What is the deployment architecture work flow? An alternate option would be to use -p 5432:5432 to bind port 5432 from the container to your machine. Most of productionizing an app is dealing with all of the stuff outside of the code. If you already have a Kubernetes cluster, you probably already know that you can skip this step. You'll need a DNS entry and an SSL certificate. Spotify R&D I am following the steps exactly in doc The app directory is the UI code, and the backend directory is the backend code. Kubectl uses the Kubernetes API to interact with the cluster. Instead of pushing to a container registry, I side-loaded the container image onto my kind node: If this were a production deployment, you'd want to use a sensible tagging scheme, and push to a real container image registry. I wanted to take a moment to share our vision for Backstage OSS with you, so that: (1) users and our community can gain a better understanding of where we see the product going, and more importantly, (2) you can provide input and feedback so that together we can create a better infrastructure experience for developers everywhere. There is also a contrib guide to deploying Backstage with To make things more tangible, lets have a look at four of the common use-cases: Creating any new software component at Spotify, such as a new microservice, is done with a few clicks in Backstage. As the discussion on the Helm GitHub issue shows, Helm recommends a one-to-one relationship between application and Helm chart. Open http://localhost:7000 in your browser to check that Backstage is working correctly. More than music, were a tech company that has always put engineers first, empowering our developers with the ability to innovate quickly and at scale. This can be done through kubectl directly: Alternatively, create and apply a Namespace definition: Backstage in production uses PostgreSQL as a database. Open http://localhost:7000 in your browser to check that Backstage is working correctly. It expose port 5432 and bind the service with Postgres pod. will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. The codebase is divided up into differentfeatures, each owned and maintained by a separate team. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. Try to follow this guide, wrote it a few days ago and it works for me. Some of these include: These challenges are definitely complex and can take many platform teams months to figure out. To work around this, we will have to forward a port inside the cluster, to one on our local machine. Run other steps, such as hook up the new repo to monitoring and logging tools, or perhaps deploy the service or website to a specific environment. If this sounds interesting or youd like to help us shape our product vision, wed love to talk. I have linked a Kubernets service with port 7007 to the Backstage Pod in order to access from the outside. Following are some different components in the Backstage web. To update the Kubernetes deployment to a newly published version of your Backstage Software Catalog and Developer Platform Edit Deploying with Kubernetes Kubernetes is a system for deploying, scaling and managing containerized applications. Backstage instance. the scope of this document. Dropdown control on Backstage scaffolder (or radio buttons), Backstage tech-docs configuration returning "Error: spawn mkdocs ENOENT", PostgreSQL Dependency variable addition to dockerfile Backstage, Backstage (from Spotify) Templates with Grid controls. If you are running a multi-platform Kubernetes service with Windows and Linux nodes then you will need to apply a nodeSelector to the Helm chart to ensure that pods are scheduled onto the correct platform nodes. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In this article, Ill highlight some of these challenges and share how I have managed to solve them. This will first check if there is a. The secrets can now be applied to the Kubernetes cluster: PostgreSQL needs a persistent volume to store data; we'll create one along with CDK8S is a tool with flexibility and extensibility at its heart. backend. Kubernetes is a system for deploying, scaling and Using the recipe published here, you can operationalize and get Backstage up and running in your Kubernetes environments in a matter of minutes. Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. Why does the impeller of torque converter sit behind the turbine? requires the first two steps. Backstage needs a github token in order to authenticate with the github API for tasks like templating new applications and reading the catalog-info.yaml files it uses to store metadata. Story Identification: Nanomachines Building Cities. This is covered in the Kind docs. This creates something more persistent beyond a Kubernetes node. In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure. cluster. Now that you know what Deployments are, let's go to the online tutorial and deploy our first app! We talk to maintainers Lee Mills and Matt Clarke from Spotify. Backstage is the natural result of that focus. Projective representations of the Lorentz group can't occur in QFT! it: There is no special wiring needed to access the PostgreSQL service. Open an issue in the GitHub repo if you want to To some observers, it may seem odd that a music company is launching a best-in-class developer portal. Switch to the newly-created example-app directory, and start the backend server: This should open a browser to localhost:3000, where you'll see the Backstage UI. Then please press the follow me button. pod. Among other things, I've not made any attempt to secure the app, and the database runs on Kubernetes, which is what you do to databases when you hate the data they contain.

Refresh the page, check Medium 's site. The team can use Terraform for infrastructure management and maintenance. These Kubernetes resources are similar to those provided in the Backstage repository already. Note: The easiest way to explore Backstage is to visit the The open-source game engine youve been waiting for: Godot (Ep. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. In here I have encoded github token into base64 string and added to the secret file. 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. Create a Kubernetes (GKE) cluster. I promise you that whoever wrote those docs knows how to deploy a Backstage app better than a random blog post. Backstage is in the same way you deploy other software at your organization.
