Apply this Deployment to the Kubernetes cluster: Beautiful! When discussing infrastructure challenges with peer companies, its clear that we are not alone in struggling with fragmentation across our developer ecosystem. You can email us at:Backstage-interest@spotify.com. In the majority of cases, the Ingress will rely on an external Load Balancer to accept initial traffic before being routed. 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. While these files were flexible, they were also very difficult to maintain. expected by PostgreSQL. instead. This error happens in the backend when it tries to connect to the configured PostgreSQL database and the specified CA is not correct. Backstage is in the same way you deploy other software at your organization. Why does the impeller of torque converter sit behind the turbine? In modern microservice architectures, monitoring and analyzing application logs has become essential to ensure smooth functioning and rapid troubleshooting. 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. Because again, a 1.3 gig Docker image is going to cause headaches when your 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. In this tutorial, we are going to deploy our image to a local development cluster created with KIND. Note that app.baseUrl and backend.baseUrl in your app-config.yaml should cluster. for the cluster. This documentation shows common examples that may be useful when deploying 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.

Deploying Backstage on AWS using ECR and EKS. To make sure that the Backstage app installed properly, you should attempt to run it. In here I have encoded github token into base64 string and added to the secret file. Note the volume type: local; this creates a volume using local disk on 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. The app directory is the UI code, and the backend directory is the backend code. 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. 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. The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. The solution is to delete this volume with In order to test the Backstage app, you'll need a running Postgres database. Hence, I prefer Pulumi over Terraform and CDK8S over Helm. 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 Kubernetes nodes. Instead, I use a tag that hopefully makes it extremely clear that this is for use on my laptop. Following is the deployment to create Kubernets namespace. More likely than not, the end user docs are going to recommend something different than what's in this post. Our internal installation of Backstage has over 100 different integrations we call them plugins. Then please press the follow me button. Deployments in Kubernetes are commonly assigned to their own This means that uninstalling and re-installing the charts with postgres.enabled set to true and The Backstage app in this post is by no means meant for production use. Enter use the standard host build with the frontend bundled and served from the First we need to install Backstage app dependencies with yarn install, generate type definitions using yarn tsc, and build all packages with yarn build. These are applications that need to be run on every node in the cluster. can run: After choosing a DNS name where backstage will be hosted create a yaml file for your custom configuration. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. to know about in the metadata block. pod. deployment itself: If you're not used to Kubernetes, this is a lot to take in. Use this snippet from the KIND docs. 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? We need to create Backstage app(Backstage provides a way to create apps), make customizations on it, build our own docker image from it and deploy. Spotify R&D cluster. Make sure to create the appropriate DNS entry in your infrastructure. Create a Kubernetes (GKE) cluster. I love learning about new technologies and sharing my learning with others. 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,. Dot product of vector with camera's local positive x-axis? Backstage requires a database to store information about the components, websites and other entities you want to track in the catalog. There is also an example of deploying on Heroku, which only 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. 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. Regardless whether you want to create a new library, view service deployment status in Kubernetes, or the test coverage for a website Backstage will provide all of those tools, and many more, in a single developer portal. I have run this setup on Minikube-based Kubernets cluster. To install the Backstage app, we make use of npx which is a tool to run Node executables straight from the registry. Engineers write technical documentation in Markdown files that live together with the code. We need to install them first. In this article. everything else. 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. Note the envFrom and secretRef - this tells Kubernetes to fill environment Copyright 2022 Backstage Project Authors. Backstage for the first time, or for those without established deployment Change into the scaffolded-app-sqlite directory which we just created, and use yarn to run a command which will build the Docker image. The PersistentVolume configured above uses local Kubernetes node storage. Has Microsoft lowered its Windows 11 eligibility criteria? When Provide a name for the deployment and the container image to deploy. All rights reserved. Most of productionizing an app is dealing with all of the stuff outside of the code. cluster, first install kubectl, the 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. Following is the Backstage Kubernets deployment. Follow to join our 1M+ monthly readers, A DevOps engineer by profession. To do this, we will use the built in port forwarding feature of kubectl. AWS Fargate and Aurora PostgreSQL. Copyright 2022 Backstage Project Authors. You can find more information about these installations from the Backstage documentations. I was feeling inspired, so I went with "example-app" for the name. An overview by Roadie. Now that you know what Deployments are, let's go to the online tutorial and deploy our first app! You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. To complete this tutorial, you will need: To run Backstage on Kuberentes, we first need to scaffold a Backstage application to work with. 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. When a deployment is created, Kubernetes builds pods to host application instances. create a similar Kubernetes Secret as we did Try to follow this guide, wrote it a few days ago and it works for me. Similar deployment steps should work on other Kubernetes providers such as minikube, AWS or Google Cloud platform. As mentioned above, Backstage need github access token. 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. This guide covers basic Kubernetes definitions needed to get Backstage up and Kubectl uses the Kubernetes API to interact with the cluster. This prevents a problem where kubernetes will attempt to find a new version of the backstage docker image on the network, instead of using the one we loaded onto the cluster earlier. The spec block describes the desired state. 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. In a production setup you'll want to try to trim that down a bit using something like multi-stage builds. Unlike other CNCF projects, Backstage does not comes with pre-built docker containers to deploy. 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 (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). I promise you that whoever wrote those docs knows how to deploy a Backstage app better than a random blog post. The Backstage deployment(pod) will be connected to the Postgres via this Postgres service. Can the Spiritual Weapon spell be used as cover? We realize this is an ambitious goal.

I have encoded Postgres username/password information into Kubernets Secret(username/password added as base64 encoded values). A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. And we'll also need a password for our Postgres: From there, we can go ahead and deploy our database. Thanks for the feedback. You can create and manage a Deployment by using the Kubernetes command line interface, Kubectl. Save the following YAML into a file called manifest.yaml. 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. Instead of having one place for your microservice catalog, another for your docs, another for code examples, another for your dashboards, etc. or To subscribe to this RSS feed, copy and paste this URL into your RSS reader. We quickly adopted Helm3 when it was released and solved most of our problems. Backstage is the natural result of that focus. 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. First, create a Kubernetes Secret for the PostgreSQL username and password. 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. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. any trouble, check the container logs from the pod: Like the PostgreSQL service above, we need to 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). Or paste the errors as well, Added now in the question can you please check it. 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. We apply this change to the cluster with the following command. A workaround is to set appConfig.backend.database.connection.ssl.rejectUnauthorized to false in the chart's values. The solution is to make sure that the contents of the configMap that holds the certificate match the CA for the PostgreSQL instance. If you run into Imagine if all your tools GCP, Bigtable, CI pipelines, TensorFlow Extended, and whatever else is hiding in your stack all had the same, easy-to-use interface. kubectl delete pvc data--postgresql-0. for PostgreSQL. We created Backstage about four years ago. While Backstage does share some characteristics with a wiki, saying that it's "like a wiki" doesn't really do the idea justice. Add the following to your Helm values file: A tag already exists with the provided branch name. Go ahead and create github personal access token from here. free up resources. I am following the steps exactly in doc But here in the yarn commands i amm getting errors , even though I am able. This cluster has no network access and thus, without setting imagePullPolicy: Never, our deployment would fail. 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." You'll want to create a separate database user for Backstage. You can change that information later by updating your Deployment; Modules 5 and 6 of the bootcamp discuss how you can scale and update your Deployments. 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.. When creating the app it will ask name of the app and database type. Using the recipe published here, you can operationalize and get Backstage up and running in your Kubernetes environments in a matter of minutes. Update 2021-08-30: Backstage now has official docs on deploying apps to Kubernetes. During CI, a beautiful-looking documentation site is created usingMkDocs, and all sites are rendered centrally in a Backstage plugin. You'll probably want to trim down the Docker image.
