If you have a specific, answerable question about how to use Kubernetes, ask it on Backstage is in the same way you deploy other software at your organization. Now Backstage web can be access via localhost:7007 from host machine. By fostering a vibrant community of . running on the same cluster, Kubernetes will inject POSTGRES_SERVICE_HOST and But here in the yarn commands i amm getting errors , even though I am able to see yarn version, i am unable to run getting tdc command not found. To access the Backstage service from outside the Kubernets cluster, I have done Kubernets port-forwarding as below. Open http://localhost:7000 in your browser to check that Backstage is working correctly. These can be used in the Backstage app-config.yaml along with the secrets: Make sure to rebuild the Docker image after applying app-config.yaml changes. Backstage requires a database to store information about the components, websites and other entities you want to track in the catalog. The secrets can now be applied to the Kubernetes cluster: PostgreSQL needs a persistent volume to store data; we'll create one along with Follow to join our 1M+ monthly readers, A DevOps engineer by profession. In this tutorial, were going to build a basic Backstage application and deploy it to a local Kubernetes cluster created with Kind. Our internal installation of Backstage has over 100 different integrations we call them plugins. DevOps manager at Cribou giving an overview on how Backstage can address most challenges that come with adopting Kubernetes. Visit me @ www.asimayub.com. Note the envFrom and secretRef - this tells Kubernetes to fill environment POSTGRES_SERVICE_PORT environment variables into our Backstage container. Does Cast a Spell make you a spellcaster? Are you sure you want to create this branch? The username is backstage, password is hunter2. This cluster has no network access and thus, without setting imagePullPolicy: Never, our deployment would fail. Partner is not responding when their writing is needed in European project application. How can I change a sentence based upon input to a command? a single-node Kubernetes cluster on your local machine: Now you can run kubectl commands and have changes applied to the minikube The main Backstage codebase does ship with a sample application we can run, but best practices dictate that we should create our own so we can customize it with our company name and other attributes. (If you didn't already try creating a hello-node application and deploying it using a container, you can do that first by following the instructions from the Hello Minikube tutorial). # Uncomment if health checks are enabled in your app: # https://backstage.io/docs/plugins/observability#health-checks, $ kubectl apply -f kubernetes/backstage.yaml, NAME READY UP-TO-DATE AVAILABLE AGE, NAME READY STATUS RESTARTS AGE, backstage -f backstage-54bfcd6476-n2jkm -c backstage, $ kubectl apply -f kubernetes/backstage-service.yaml. Kubernetes definitions in a single file and apply them at the same time. Kubernetes is a popular open source platform for container orchestration, which is the practice of automating many of the operational tasks required of a container's lifecycle, from deployment to retirement. k8s.gcr.io image registry will be frozen from the 3rd of April 2023.Images for Kubernetes 1.27 will not available in the k8s.gcr.io image registry.Please read our announcement for more details. Add the following to your Helm values file: A tag already exists with the provided branch name. Note that I'm using Fedora, and networking might work different on, say, Docker for Mac. live demo site. While Backstage does share some characteristics with a wiki, saying that it's "like a wiki" doesn't really do the idea justice. The values can be generated All rights reserved. Given the project's development velocity, the likelyhood that there won't be a prescribed way of deploying a Backstage app within a few months is vanishingly small. A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. 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. Some resources created by these charts are meant to survive after upgrades and even after uninstalls. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. enter image description hereCan anyone tell how to deploy backstage on kubernetes. Developers choose between a number of standard templates all with best-practices built in. with the given pod template, which again contains Kubernetes metadata and a Projective representations of the Lorentz group can't occur in QFT! as in example? Making statements based on opinion; back them up with references or personal experience. Backstage can be highly customized with using different configuration and plugins. type of PersistentVolume. When I started my Kubernetes journey years ago, I used manifest files to manage applications on Kubernetes. We talk to maintainers Lee Mills and Matt Clarke from Spotify. Therefore we don't want to try to connect to pods directly, but 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. 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. To update the Kubernetes deployment to a newly published version of your Deployments in Kubernetes are commonly assigned to their own To install the Backstage app, we make use of npx which is a tool to run Node executables straight from the registry. The best way to deploy Backstage is in the same way you deploy other software at your organization. Deploying Backstage on AWS using ECR and EKS. 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. match what we're forwarding here (port omitted in this example since we're using This made maintaining those charts very difficult. Backstage can be run with Sqlite and Postgres databases. Since it's An overview by Roadie. This is a good choice if you're looking to be able to scale the two independently, but for simple deployments it's more complexity than one needs. @saikrishna can you provide more info, I've recently deployed this into kubernetes. This could be things like logging or monitoring agents. Has Microsoft lowered its Windows 11 eligibility criteria? Engineers write technical documentation in Markdown files that live together with the code. By default, Backstage's frontend and backend are served separately. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. 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.. Context Spotify uses adocs-like-codeapproach. Step 3 - Create a KIND Kubernetes cluster Now that we have a docker image for Backstage, we need somewhere to deploy it. . Open an issue in the GitHub repo if you want to on common infrastructure, it would be a great benefit to the community. object format for its entity definition files! A workaround is to set appConfig.backend.database.connection.ssl.rejectUnauthorized to false in the chart's values. 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. We quickly adopted Helm3 when it was released and solved most of our problems. We realize this is an ambitious goal. everything else. Backstage gives developers a uniform overview of all their resources, regardless of how and where they are running, as well as an easy way to onboard and start using those tools. You may see different results if youre using a different version. You'll also want to write at least a minimal .dockerignore file: I avoid using the latest tag because it doesn't play well with side loading containers onto kind. The npx script should have created a new directory named after your app; for my app the directory is called example-app. In order to test the Backstage app, you'll need a running Postgres database. The Deployment instructs Kubernetes In the majority of cases, the Ingress will rely on an external Load Balancer to accept initial traffic before being routed. For any Backstage configuration secrets, such as authorization tokens, we can This command will deploy the following pieces: Backstage frontend Backstage backend with scaffolder and auth plugins (optional) a PostgreSQL instance lighthouse plugin ingress After a few minutes Backstage should be up and running in your cluster under the DNS specified earlier. way to deploy to an existing Kubernetes setup is the same way you deploy 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. Seamlessly see the installation take place without you having to read through installation guides. We need some special settings on our cluster so we can configure ingress in the cluster with Nginx. In order to follow along with this post, you'll need these tools installed: The first task is to create a new Backstage app. 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. 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. Running the command below will install Backstage. We apply this change to the cluster with the following command. Applications need to be packaged into one of the supported container formats in order to be deployed on Kubernetes. mapping translates normal HTTP port 80 to the backend http port (7007) on the At the moment, forking the repo seems to net you a much easier onboarding experience: it comes with Dockerfiles, example Kubernetes manifests, etc. is there a chinese version of ex. Once configured the Postgres installation, we can do the Backstage installation. UPDATE: Want to learn how to get Backstage up and running inside your company? 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. When a repository on a container registry (for example, ECR on AWS). Find centralized, trusted content and collaborate around the technologies you use most. Deployment (one or more instances of an application) that we'd like Kubernetes Enter Backstage comes with a built in command to help you build a Docker image which we can deploy into a Kubernetes cluster. This At Spotify, we deploy software generally by: This method is covered in Building a Docker image and will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. the scope of this document. cluster. Kubernetes canary deployment is a technique for rolling out new features or changes to a small subset of users or servers before releasing the update to the entire system. published postgres:13.2-alpine Docker deployment itself: If you're not used to Kubernetes, this is a lot to take in. Backstage provides tooling to build Docker images, but can be deployed with or A Kubernetes plugin was recently added. The solution is to make sure that the contents of the configMap that holds the certificate match the CA for the PostgreSQL instance. In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure. Everything connected with Tech & Code. We should now see that an image has been built successfully. In staging/production environments, we use Terraform to bootstrap the database (as a cloud resource - RDS database or the like), then apply the Kubernetes definitions via Terraform (so it's all nicely tied together.) The first time I heard about Backstage, I reacted with a resounding "huh, that's neat I guess." The object definitions might look familiar, since Backstage is designed to fit this model and This is most of the way to a full production deployment of Backstage on Yet everyone is required to know and understand Terraform, GCP/AWS/Azure CLIs, Gitlab CI, Prometheus, Kubernetes, Docker, various monitoring and alerting tools, and much, much more. The deployment and pod are running in the cluster. Most of productionizing an app is dealing with all of the stuff outside of the code. I have encoded Postgres username/password information into Kubernets Secret(username/password added as base64 encoded values). 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. I was feeling inspired, so I went with "example-app" for the name. This folder contains Helm charts that can easily create a Kubernetes deployment of a demo Backstage app. And we learned a thing or two via the feedback we received. The solution is to delete this volume with This provides a self-healing mechanism to address machine failure or maintenance. Phase 3: Ecosystem (later) Everyone's infrastructure stack is different. Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. 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. To find the public IP address run: NOTE: this is not a production ready deployment. There's a few additional steps to that will likely be needed beyond 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 . the minikube internal Docker registry and then rebuild the image to install 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, Python, Java, and Go. If it's not already installed you In here it setup Postgres username, password, host, port information and Backstage github access token via environment variables using the Kubernets Secrets and ConfigMaps files. Thank you for taking the time to read my post, I really appreciate it. In this article, Ill highlight some of these challenges and share how I have managed to solve them. referenced the volume created for the deployment, and given it the mount path I've tried to describe Backstage to people before, and the response is usually something along the lines of "so like a wiki?" reveal, you can forward a local port to the service: This shows port 7007 since port-forward doesn't really support services, so This is covered in the Kind docs. Go ahead and create github personal access token from here. Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. managing containerized applications. Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). 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. This directory should contain a packages directory, which has an app and backend directory. 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). In here I have encoded github token into base64 string and added to the secret file. Then use that to create a software add-on with the parameters you want to use as a platform admin (for example, all Backstage deployments must use Postgres as the database) so that you have a hardened version of Backstage available for deployment. 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." Make sure to create the appropriate DNS entry in your infrastructure. Kubernetes is a system for deploying, scaling and We created Backstage about four years ago. As before, open http://localhost:7000 in your browser to view Backstage. Once other resources come into play (databases, queueing, etc. a triple dash. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. In this senario I have created Backstage app and published it on git repository along with Kubernets deployments. Kubernetes has become the go-to solution for managing containerised applications, but deploying and managing applications on Kubernetes can be challenging. Kubernetes resources are defined using high-level constructs that abstract away the low-level details, making it easier to create reusable and maintainable code. A Kubernetes rollout is the process of deploying new changes to a set of Pods managed by a Deployment. Provide a name for the deployment and the container image to deploy. 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. A Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. The Kubernetes Service is not exposed for external connections from outside the 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. Why does the impeller of torque converter sit behind the turbine? There is also a contrib guide to deploying Backstage with The Linux Foundation has registered trademarks and uses trademarks. How can the mass of an unstable composite particle become complex? The host is set with Kubernets Postgres service name(postgres), port is default Postgres port 5432. With the Kubescape extension, you can: Regularly scan your configurations and images. 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. 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 Backstage app configured to run with Postgres database, so we need setup Postgres installation first. autoscale a deployment. 2023 Larder Software Limited. Our homegrown CI system uses Jenkins under the hood, but Spotify engineers dont need to know that. from Backstage app deployments, we can create a separate Kubernetes deployment Here we've requested Kubernetes Now that you know what Deployments are, let's go to the online tutorial and deploy our first app! pod port. We need to install them first. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. I have changed the app name in with below configurations on app-config.yaml. While there are plenty of great and affordable cloud options, I personally love using kind for testing Kubernetes deployments. Kubectl uses the Kubernetes API to interact with the cluster. But if youdig deeper, youll find that since the very beginning, Spotify has been known for its agile, autonomous engineering culture. What is the deployment architecture work flow? Consider a team that wants to deploy something to the cloud. This tool is part of the Node.js installation. use the standard host build with the frontend bundled and served from the This means that uninstalling and re-installing the charts with postgres.enabled set to true and You should be able to see the kube-system Kubernetes pods running: When you're done with the tutorial, use minikube stop to halt the cluster and Configuring a connection to an existing PostgreSQL instance is possible through the chart's values. Were going to use Sqlite3 for this tutorial. provider. While Spotify has many awesome engineers, not every engineer is well-versed in our chosen cloud-provider tooling. 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. cluster. First, create a Kubernetes Secret for the PostgreSQL username and password. On my laptop it clocked in at around a 1.3G, which is frankly terrible. The open-source game engine youve been waiting for: Godot (Ep. Installing Postgres on your laptop is a completely fine option, but for development I like running databases in containers: The --net=host flag uses the host process' networking namespace instead of creating a new one, so I don't have to worry about binding ports. The codebase is divided up into differentfeatures, each owned and maintained by a separate team. SealedSecrets or other solutions. . Backstage unifies all your infrastructure tooling, services, and documentation with a single, consistent UI. Kubernetes will automatically pick Docker as the default container runtime.
