A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. Visualize your RBAC rules. So, in the spirit of too much free time on a Saturday, I decided to try to deploy a Backstage app to Kubernetes, Some of the key features of Backstage include: Asking for help, clarification, or responding to other answers. We need to install them first. 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. pointing to a container registry where built Docker images are hosted. Create the Kubernetes Service descriptor: The selector here is telling the Service which pods to target, and the port Backstage can be run with Sqlite and Postgres databases. This is done by creating . In Kubernetes, an Ingress is an API object that manages the routing of external requests to one of the many possible internal services in a Kubernetes cluster. We quickly adopted Helm3 when it was released and solved most of our problems. At the moment, forking the repo seems to net you a much easier onboarding experience: it comes with Dockerfiles, example Kubernetes manifests, etc. 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. You can use Azure Pipelines to deploy to Azure Kubernetes Service and Kubernetes clusters offered by other cloud providers. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. This directory should contain a packages directory, which has an app and backend directory. Backstage instance. We'll use this image to create a Kubernetes deployment. The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Engineers write technical documentation in Markdown files that live together with the code. 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. We can double-check that the change was applied successfully by inspecting our backstage Kubernetes pod. By default, Backstage's frontend and backend are served separately. 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. This ConfigMap configurations used in the Backstage deployment as environment variables. type of PersistentVolume. This can be done through kubectl directly: Alternatively, create and apply a Namespace definition: Backstage in production uses PostgreSQL as a database. Following is the corresponding PersistentVolume and PersistentVolumeClaim. for PostgreSQL. Backstage can be as simple as a services catalog or as powerful as the UX layer for your entire tech infrastructure. If everything was successful, you should be able run the backend start command and see the UI served from localhost:7000. Deploying Backstage on AWS using ECR and EKS. Would you like to read more such interesting posts? Kubectl uses the Kubernetes API to interact with the cluster. For storing secrets in Git, consider suggest an improvement. Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). Try to follow this guide, wrote it a few days ago and it works for me. On my laptop it clocked in at around a 1.3G, which is frankly terrible. 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. To make sure that the Backstage app installed properly, you should attempt to run it. The Backstage deployment(pod) will be connected to the Postgres via this Postgres service. A Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. This can While Backstage does share some characteristics with a wiki, saying that it's "like a wiki" doesn't really do the idea justice. Be sure to enable The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. To some observers, it may seem odd that a music company is launching a best-in-class developer portal. This guide covers basic Kubernetes definitions needed to get Backstage up and They interact directly with GitHub Enterprise and Backstage. SealedSecrets or other solutions. everything else. Running the command below will install Backstage. We apply this change to the cluster with the following command. Hence, I prefer Pulumi over Terraform and CDK8S over Helm. image. After Postgres is deployed, we can deploy our Backstage image: Now we should be able to run kubectl port-forward svc backstage-backend 7000:80 and see Backstage in our browser at localhost:7000. The object definitions might look familiar, since 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 is most of the way to a full production deployment of Backstage on I have changed the app name in with below configurations on app-config.yaml. What's wrong with my argument? The open-source game engine youve been waiting for: Godot (Ep. This could be things like logging or monitoring agents. When discussing infrastructure challenges with peer companies, its clear that we are not alone in struggling with fragmentation across our developer ecosystem. Services keep track of pods and direct When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. @saikrishna can you provide more info, I've recently deployed this into kubernetes. Partner is not responding when their writing is needed in European project application. is there a chinese version of ex. correct pods. The Linux Foundation has registered trademarks and uses trademarks. Please clone the repo and continue the post. View the GKE Pod logs (Output of your python code) Prerequisites. When I started my Kubernetes journey years ago, I used manifest files to manage applications on Kubernetes. managing containerized applications. from Backstage app deployments, we can create a separate Kubernetes deployment Kubernetes definitions in a single file and apply them at the same time. 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. 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. Since it's There are many different tools and patterns for Kubernetes clusters, so the best 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. 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. Provide a name for the deployment and the container image to deploy. To work around this, we will have to forward a port inside the cluster, to one on our local machine. Thanks for the feedback. 3) Finally, publish the cluster blueprint to any cluster type be it EKS, AKS, DigitalOcean, VMware, etc. A workaround is to set appConfig.backend.database.connection.ssl.rejectUnauthorized to false in the chart's values. 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. run as a stateless application with an external PostgreSQL database. a repository on a container registry (for example, ECR on AWS). When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. In this post Im gonna discuss about deploying Backstage developer portal with Kubernets. 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. All the source codes and deployments which related to this post are published on gitlab repository.

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 . I have published it in gitlab here. It gets harder for individual engineers to find and use all these distinct tools. We cant do it alone.

Azure DevOps Services. create a similar Kubernetes Secret as we did 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. 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. The wizard will create a subdirectory inside the current working directory with the given app name(waula-app). report a problem Backstage run on port 7007 inside the Pod. What's the difference between a power rail and a signal line? match what we're forwarding here (port omitted in this example since we're using This tool is part of the Node.js installation. live demo site. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. 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. Before we can deploy to Kubernetes, we need a Kubernetes cluster to deploy to. Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. Are you sure you want to create this branch? This means that uninstalling and re-installing the charts with postgres.enabled set to true and 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 npx script should have created a new directory named after your app; for my app the directory is called example-app. without Docker on many different infrastructures. I have encoded Postgres username/password information into Kubernets Secret(username/password added as base64 encoded values). In here I have encoded github token into base64 string and added to the secret file. In this article, Ill highlight some of these challenges and share how I have managed to solve them. We have a new website just for adopters: backstage.spotify.com. will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. and to write about the experience in order to give others a head start. Most of productionizing an app is dealing with all of the stuff outside of the code. and so I thought it might be time to investigate it properly. It expose port 5432 and bind the service with Postgres pod. Backstage build with Node.js and Yarn. a single-node Kubernetes cluster on your local machine: Now you can run kubectl commands and have changes applied to the minikube control plane schedules the application instances included in that Deployment to run on individual Nodes in the But in this case, it's a lot easier to examine the ConfigMap to check for typos, since it keeps me from having to base64 decode the string. on common infrastructure, it would be a great benefit to the community. In summary, Helm is a great tool for managing Kubernetes workloads, but it has its limitations, especially when it comes to maintaining charts over time. You signed in with another tab or window. We talk to maintainers Lee Mills and Matt Clarke from Spotify. requires the first two steps. A production deployment would also require a stable URL and SSL certificate, which I didn't attempt to set up for this post. Note the volume type: local; this creates a volume using local disk on You can find more information about these installations from the Backstage documentations. 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. First create a yaml file with the configuration you want to override, for example backstage-prod.yaml: For the CA, create a configMap named
