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). 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? Use kind to create a Kubernetes cluster to work with. More likely than not, the end user docs are going to recommend something different than what's in this post. pod. 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/. The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. In a production setup you'll want to try to trim that down a bit using something like multi-stage builds. cluster. Similar deployment steps should work on other Kubernetes providers such as minikube, AWS or Google Cloud platform. We should now see that an image has been built successfully. deployment itself: If you're not used to Kubernetes, this is a lot to take in. The username is backstage, password is hunter2. Now that the image is loaded, we can create a Backstage deployment and a service to expose it on an IP inside 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. The solution is to make sure that the contents of the configMap that holds the certificate match the CA for the PostgreSQL instance. When creating the app it will ask name of the app and database type. A Kubernetes plugin was recently added. Dot product of vector with camera's local positive x-axis? 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? how to create and update instances of your application. 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. way to deploy to an existing Kubernetes setup is the same way you deploy the minikube internal Docker registry and then rebuild the image to install Add the following to your Helm values file: A tag already exists with the provided branch name. To do so, you create a Kubernetes Deployment configuration. Therefore we don't want to try to connect to pods directly, but Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. . 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. Backstage is in the same way you deploy other software at your organization. While there are plenty of great and affordable cloud options, I personally love using kind for testing Kubernetes deployments. Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. For a grand How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Apply the storage volume and claim to the Kubernetes cluster: Now we can create a Kubernetes Deployment descriptor for the PostgreSQL database Episode #136: Backstage, with Lee Mills and Matt Clarke. For example, if you have a logging agent that you want to run on every node in your cluster, you could use a DaemonSet to make sure that there is an instance of 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. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. run as a stateless application with an external PostgreSQL database. 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. A production deployment would also require a stable URL and SSL certificate, which I didn't attempt to set up for this post. 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. Backstage run on port 7007 inside the Pod. dynamically. Note that I'm using Fedora, and networking might work different on, say, Docker for Mac. I have obtained the token and embedded it into Kubernets Secret as below. The Postgres storage deployed with persistent volume. 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,. create a Kubernetes Service for Backstage to handle connecting requests to the Deployments in Kubernetes are commonly assigned to their own This post marks a very specific point in time of a nascent technology. 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. These charts depend on the nginx-ingress controller being present in the cluster. The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. 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.. Ownership information is automatically captured in our service/software catalog and users can see a list of all the services they own. This documentation shows common examples that may be useful when deploying To do this, we will use the built in port forwarding feature of kubectl. Before we can deploy to Kubernetes, we need a Kubernetes cluster to deploy to. Then please press the follow me button. ), each engineer requires even more tools and domain-specific knowledge (or disciplines), from backend to machine learning, to mobile and data. After watching some of the demos, I had an "a-ha" moment, and at this point I'm pretty excited about Backstage and the idea of developer portals cutting down on the number of touch points an engineer needs to interact with to get things done. mapping translates normal HTTP port 80 to the backend http port (7007) on the kubectl delete pvc data--postgresql-0. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. 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. Open an issue in the GitHub repo if you want to All rights reserved. referenced the volume created for the deployment, and given it the mount path In this article, Ill highlight some of these challenges and share how I have managed to solve them. I was feeling inspired, so I went with "example-app" for the name. Deploying Backstage in Kubernetes With Enterprise-Grade Governance and Automation Introduction To Backstage. requires the first two steps. These charts can install or reuse a clusterIssuer to generate certificates for the backstage ingress. For this example, we'll correct pods. So, I wanted to take this opportunity to further explain what were trying to do with Backstage and more importantly, what we want to give to the greater engineering community beyond Spotify. everything else. Change into the scaffolded-app-sqlite directory which we just created, and use yarn to run a command which will build the Docker image. 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. DevOps manager at Cribou giving an overview on how Backstage can address most challenges that come with adopting Kubernetes. to isolate services in a multi-tenant environment. Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. reveal, you can forward a local port to the service: This shows port 7007 since port-forward doesn't really support services, so After inputting some metadata about your service, a new repository is created with a hello world service that automatically builds and deploys in production on Kubernetes (GKE). It will also help me in writing more such interesting posts. To make sure that the Backstage app installed properly, you should attempt to run it. I have changed the app name in with below configurations on app-config.yaml. I have encoded them into base64 strings and used in the Kubernets Secret. For a list of trademarks of The Linux Foundation, please see our Trademark Usage page: https://www.linuxfoundation.org/trademark-usage, 5. Backstage instance. Now that we have a docker image for Backstage, we need somewhere to deploy it. image. claims can ask for only part of a volume as well. live demo site. 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). to know about in the metadata block. will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. Our local KIND kubernetes cluster doesnt provide a way to access Backstage from our local machine, which is outside the cluster. Following is the deployment to create Kubernets namespace. During CI, a beautiful-looking documentation site is created usingMkDocs, and all sites are rendered centrally in a Backstage plugin. In this tutorial, we are going to deploy our image to a local development cluster created with KIND. A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. The downside is that our data will be stored in memory, and will be lost if we upgrade or restart our Backstage instance or Kubernetes pod. The Backstage app configurations resides in the app directory(e.g waula-app in my case). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. It is simpler and quicker to get set up with Backstage and Sqlite3. 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. To isolate the database match what we're forwarding here (port omitted in this example since we're using Would the reflected sun's radiation melt ice in LEO? This is covered in the Kind docs. # 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 will automatically pick Docker as the default container runtime. Were going to use Sqlite3 for this tutorial. Now we can deploy the Backstage with Kubernets. Refresh the page, check Medium 's site. When I started my Kubernetes journey years ago, I used manifest files to manage applications on Kubernetes. 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 expose the Postgres to outside I have defined below Kubernets service. create a similar Kubernetes Secret as we did The PersistentVolume configured above uses local Kubernetes node storage. This guide covers basic Kubernetes definitions needed to get Backstage up and Developers choose between a number of standard templates all with best-practices built in. Backstage provides tooling to build Docker images, but can be deployed with or suggest an improvement. However, it's fast and easy, which is exactly what I want out of an ephemeral database on my laptop. Note: The easiest way to explore Backstage is to visit 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. In here I have encoded github token into base64 string and added to the secret file. 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. Deployment Rollouts: Check History, Pause, Resume, or Undo/Rollback Changes. Before we can use it, we have to load it into the cluster. This way you will get notified about my new posts. from Backstage app deployments, we can create a separate Kubernetes deployment Create the Kubernetes Service descriptor: The selector here is telling the Service which pods to target, and the port pod port. The secrets can now be applied to the Kubernetes cluster: PostgreSQL needs a persistent volume to store data; we'll create one along with When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. Backstage app configured to run with Postgres database, so we need setup Postgres installation first. We need some special settings on our cluster so we can configure ingress in the cluster with Nginx. 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. You'll want observability into the system, alerting, etc. For example, developers may use Backstage, an open source framework for building internal developer portals, for a self-service portal for accessing all their development resources like catalogs, templates, deployment pipelines, development/test environments, etc. Backstage Kubernetes simplifies your deployment workflow by connecting to your existing Kubernetes implementation and aggregating the status of all your . Some of the key features of Backstage include: I promise you that whoever wrote those docs knows how to deploy a Backstage app better than a random blog post. Instead, I use a tag that hopefully makes it extremely clear that this is for use on my laptop. for the cluster. Read more about these usecases from Spotify Engineering blog. This creates You'll need a DNS entry and an SSL certificate. rather create a Kubernetes Service. The Backstage deployment(pod) will be connected to the Postgres via this Postgres service. Youll notice that we have set the imagePullPolicy to Never. To work around this, we will have to forward a port inside the cluster, to one on our local machine. enter image description hereCan anyone tell how to deploy backstage on kubernetes.
