Therefore we don't want to try to connect to pods directly, but If it's not already installed you The template spec shows one container, created from the A Backstage app is a lighter-weight version of Backstage that's meant to be deployed by end users, as opposed to those who are developing Backstage itself. Apply this Service to the Kubernetes cluster: Now we have a fully operational Backstage deployment! A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. Deploy Spotify Backstage with Kubernetes | by (x.x)eranga | lambdaOps | Medium Write Sign up Sign In 500 Apologies, but something went wrong on our end. Engineers write technical documentation in Markdown files that live together with the code. Kubectl uses the Kubernetes API to interact with the cluster. Backstage provides tooling to build Docker images, but can be deployed with or I have published it in gitlab here. Following are the main steps of Backstage installation on Kubernets. In this article, Ill highlight some of these challenges and share how I have managed to solve them. All rights reserved. Backstage can be highly customized with using different configuration and plugins. 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. Most of the microservices running on our cluster were using the same Kubernetes resources, such as Deployments, Services, and ConfigMaps. 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.. the scope of this document. Launching the CI/CD and R Collectives and community editing features for How do we deploy the Backstage App in AWS? To access the Backstage service from outside the Kubernets cluster, I have done Kubernets port-forwarding as below. then apply the changes with kubectl apply -f kubernetes/backstage.yaml. Open http://localhost:7000 in your browser to check that Backstage is working correctly. DaemonSets are great for running a single instance of an application on every node in the cluster. run as a stateless application with an external PostgreSQL database. pointing to a container registry where built Docker images are hosted. There's a few additional steps to that will likely be needed beyond This is most of the way to a full production deployment of Backstage on Backstage is designed to fit this model and run as a stateless application with an external PostgreSQL database. We cant do it alone. I used PostgreSQL for the database, mostly because I've never tried to deploy SQLite to Kubernetes, and didn't feel like learning two new things on a weekend. 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. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. Backstage Docker image, update the image tag reference in backstage.yaml and We apply this change to the cluster with the following command. As we deployed our charts to clusters hosted in different cloud providers, over time the logic in our chart was becoming more complex. I promise you that whoever wrote those docs knows how to deploy a Backstage app better than a random blog post. Consider a team that wants to deploy something to the cloud. This directory should contain a packages directory, which has an app and backend directory. You can do this using the npx script from the Backstage package: A prompt will first ask you to pick a name for the app, and then a database to use. It will also help me in writing more such interesting posts. More likely in a production scenario, you'd want to use a more If you run into See the YouTube video to see this up and running in action in 10 minutes: Deploying Backstage in Kubernetes With Enterprise-Grade Governance and Automation, Customer-Managed VPC & IAM with Restrictions, Pull container images from only ECR registry, Operationalizing Backstage in the Enterprise, How To Get Started With This Methodology in Rafay, extensible plugin ecosystem (for ex. Next, install minikube. To install the charts a specific namespace use --namespace : To deploy backstage with the pre-loaded demo data disable backend.demoData: For more customization options take a look at the values.yaml file. The secrets can now be applied to the Kubernetes cluster: PostgreSQL needs a persistent volume to store data; we'll create one along with How can the mass of an unstable composite particle become complex? What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? The Backstage app configurations resides in the app directory(e.g waula-app in my case). This file contains definitions for two different kinds, separated by a line with To test out these concepts locally before deploying to a production Kubernetes Once you've created a Deployment, the Kubernetes Everyone knows about Okta, Auth0, and all the other identity services people pay for but did you know there's an amazing open-source alternative? Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). 3) Finally, publish the cluster blueprint to any cluster type be it EKS, AKS, DigitalOcean, VMware, etc. 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. backend. Note the envFrom and secretRef - this tells Kubernetes to fill environment 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. Developers choose between a number of standard templates all with best-practices built in. Following are the main steps of Postgres deployment on Kubernets. 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. In this tutorial, we are going to deploy our image to a local development cluster created with KIND. Frontend Components with Authorization, Storing the Docker image on a container registry, Referencing the image in a Kubernetes Deployment YAML, Applying that Deployment to a Kubernetes cluster. Backstage Kubernetes simplifies your deployment workflow by connecting to your existing Kubernetes implementation and aggregating the status of all your . suggest an improvement. 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. external load balancer. You may see different results if youre using a different version. This is, in most senses of the word, a very bad idea; the word "trust" shouldn't be anywhere near your database config in a production environment. mapping translates normal HTTP port 80 to the backend http port (7007) on the At Spotify, we deploy software generally by: This method is covered in Building a Docker image and We've also be hosted internally in your infrastructure, or a managed one offered by a cloud 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. 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. cluster. the default HTTP port 80): If you're using an auth provider, it should also have this Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. Instead, I use a tag that hopefully makes it extremely clear that this is for use on my laptop. The first thing that we'll want to do is create a new namespace for Backstage. Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Can you be more specific? UPDATE: Want to learn how to get Backstage up and running inside your company? 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. The Pod in this tutorial has only one Container. A production deployment would also require a stable URL and SSL certificate, which I didn't attempt to set up for this post. But if youdig deeper, youll find that since the very beginning, Spotify has been known for its agile, autonomous engineering culture. 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. claims can ask for only part of a volume as well. 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. Finally, we can deploy Backstage to Kubernetes. deployment itself: If you're not used to Kubernetes, this is a lot to take in. as in example? To do this, we will use the built in port forwarding feature of kubectl. Because again, a 1.3 gig Docker image is going to cause headaches when your Since it's The spec block describes the desired state. Backstage build with Node.js and Yarn. This with the given pod template, which again contains Kubernetes metadata and a Why did the Soviets not shoot down US spy satellites during the Cold War? 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. Our local KIND kubernetes cluster doesnt provide a way to access Backstage from our local machine, which is outside the cluster. 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). While exciting, Backstage is still very new technology, so the docs aren't quite stable yet for onboarding new users. Apply the storage volume and claim to the Kubernetes cluster: Now we can create a Kubernetes Deployment descriptor for the PostgreSQL database A Kubernetes object is a way to tell the . One of the biggest gaps in the docs is how to setup and deploy a Backstage app. Our mobile apps are developed by many different teams. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. create a Kubernetes Service for Backstage to handle connecting requests to the Once other resources come into play (databases, queueing, etc. Note that app.baseUrl and backend.baseUrl in your app-config.yaml should Now that we have a docker image for Backstage, we need somewhere to deploy it. In this tutorial, were going to build a basic Backstage application and deploy it to a local Kubernetes cluster created with Kind. To complete this tutorial, you will need: To run Backstage on Kuberentes, we first need to scaffold a Backstage application to work with. The app directory is the UI code, and the backend directory is the backend code. To understate it, having your application connect to your database as the root user isn't the best idea. Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. is there a chinese version of ex. The values can be generated I am following the steps exactly in doc But here in the yarn commands i amm getting errors , even though I am able. Yesterday, we released the open source version ofBackstage, our homegrown developer portal. Again, this is not a production-grade deployment. create a similar Kubernetes Secret as we did Change into the scaffolded-app-sqlite directory which we just created, and use yarn to run a command which will build the Docker image. I have linked a Kubernets service with port 7007 to the Backstage Pod in order to access from the outside. It looks like nothing has changed, but this page is being rendered inside our Kubernetes cluster and exposed to the browser. Copyright 2022 Backstage Project Authors. 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. First, create a Kubernetes Secret for the PostgreSQL username and password. Deployment (one or more instances of an application) that we'd like Kubernetes ), each engineer requires even more tools and domain-specific knowledge (or disciplines), from backend to machine learning, to mobile and data. Everything connected with Tech & Code. on the command line: Note: Secrets are base64-encoded, but not encrypted. More likely than not, the end user docs are going to recommend something different than what's in this post. We need to install them first. The username is backstage, password is hunter2. This follows similar steps as the PostgreSQL deployment. This cluster has no network access and thus, without setting imagePullPolicy: Never, our deployment would fail. This will first check if there is a. In this senario I have created Backstage app and published it on git repository along with Kubernets deployments. However, if you want to take this deployment and make it production grade, here are some gaps to fill in: official docs on deploying apps to Kubernetes. If an app developer on one team wants to understand how their feature is affecting overall app performance, theres a plugin for that: Developers can also look at crashes, releases, test coverage over time and many more tools in the same location. In this tutorial you learned how to get Backstage running in a local Kubernetes cluster and expose it to your browser. CDK8S offers a more flexible and extensible approach to managing Kubernetes applications, making it a great tool to consider for your Kubernetes deployment needs. There are two built in database options, Sqlite and PostgreSQL. kubectl delete pvc data--postgresql-0. In this case, we're claiming the whole volume - but Backstage run on port 7007 inside the Pod.
