desired state. For an example app-config.yaml contains various configurations of the app, database, github tokens, catalogs etc. We realize this is an ambitious goal. While our version of Backstage has had the benefit of time to mature and evolve, the first iteration of our open-source version is still nascent. everything else. Note that I'm using Fedora, and networking might work different on, say, Docker for Mac. Our internal installation of Backstage has over 100 different integrations we call them plugins. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. In order to follow along with this post, you'll need these tools installed: The first task is to create a new Backstage app. The deployment and pod are running in the cluster. Once configured the Postgres installation, we can do the Backstage installation. Backstage is the natural result of that focus. for the cluster. If this sounds interesting or youd like to help us shape our product vision, wed love to talk. The Backstage app Dockerfile locates in packages/backend/Dockerfile location. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. This provides a self-healing mechanism to address machine failure or maintenance. 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 . Context The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. Launching the CI/CD and R Collectives and community editing features for How do we deploy the Backstage App in AWS? This way you will get notified about my new posts. Deployment (one or more instances of an application) that we'd like Kubernetes Most of the microservices running on our cluster were using the same Kubernetes resources, such as Deployments, Services, and ConfigMaps. browse your Kubernetes-deployed Backstage instance. Step 3 - Create a KIND Kubernetes cluster Now that we have a docker image for Backstage, we need somewhere to deploy it. View the GKE Pod logs (Output of your python code) Prerequisites. If any security-conscious engineers are still reading this, they'll notice that I put the Postgres password in a ConfigMap instead of a Secret. We should now see that an image has been built successfully. Services keep track of pods and direct You probably want to use a database outside of Kubernetes. Next, install minikube. This folder contains Helm charts that can easily create a Kubernetes deployment of a demo Backstage app. as in example? way to deploy to an existing Kubernetes setup is the same way you deploy Were going to use Sqlite3 for this tutorial. We have a new website just for adopters: backstage.spotify.com. running on the same cluster, Kubernetes will inject POSTGRES_SERVICE_HOST and The values can be generated cluster. Would you like to read more such interesting posts? For production purposes, this image tag will generally be a full-fledged URL In this tutorial, we are going to deploy our image to a local development cluster created with KIND. The solution is to delete this volume with The best way to deploy Visit me @ www.asimayub.com. A production deployment would also require a stable URL and SSL certificate, which I didn't attempt to set up for this post. If it's not already installed you This In this case, we're claiming the whole volume - but can run: After choosing a DNS name where backstage will be hosted create a yaml file for your custom configuration. Are you sure you want to create this branch? Refresh the page, check Medium 's site. These charts depend on the nginx-ingress controller being present in the cluster. The Postgres storage deployed with persistent volume. So, in the spirit of too much free time on a Saturday, I decided to try to deploy a Backstage app to Kubernetes, 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. As companies adopt more open-source tooling, and build more infrastructure internally, the complexity grows. 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. A Kubernetes Pod is a group of one or more Containers, tied together for the purposes of administration and networking. This could be things like logging or monitoring agents. For a list of trademarks of The Linux Foundation, please see our Trademark Usage page: https://www.linuxfoundation.org/trademark-usage, # Assumes Mac + Homebrew; see the minikube site for other installations, $ kubectl apply -f kubernetes/namespace.yaml, $ kubectl apply -f kubernetes/postgres-secrets.yaml, $ kubectl apply -f kubernetes/postgres-storage.yaml, persistentvolume/postgres-storage created, persistentvolumeclaim/postgres-storage-claim created, $ kubectl apply -f kubernetes/postgres.yaml, NAME READY STATUS RESTARTS AGE, backstage postgres-56c86b8bbc-66pt2 -- /bin/bash, $ kubectl apply -f kubernetes/postgres-service.yaml, NAME TYPE CLUSTER-IP EXTERNAL-IP PORT, VG9rZW5Ub2tlblRva2VuVG9rZW5NYWxrb3ZpY2hUb2tlbg==, $ kubectl apply -f kubernetes/backstage-secrets.yaml. 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.. correct pods. 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. Backstage app configured to run with Postgres database, so we need setup Postgres installation first. Once other resources come into play (databases, queueing, etc. Before we can use it, we have to load it into the cluster. Our homegrown CI system uses Jenkins under the hood, but Spotify engineers dont need to know that. Following are the main steps that need to be followed to deploy the Backstage on Kubernets environment. auto generated passwords will fail. It was built at Spotify and both open sourced and donated to the CNCF in 2020. Now that you know what Deployments are, let's go to the online tutorial and deploy our first app! Asking for help, clarification, or responding to other answers. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Some resources created by these charts are meant to survive after upgrades and even after uninstalls. autoscale a deployment. The Pod in this tutorial has only one Container. contributed guide To do this, we will use the built in port forwarding feature of kubectl. What's the difference between a power rail and a signal line? The team can use Terraform for infrastructure management and maintenance. 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.) Read more about configuring Kubernets with Minikube from here. referenced the volume created for the deployment, and given it the mount path something more persistent beyond a Kubernetes node. reveal, you can forward a local port to the service: This shows port 7007 since port-forward doesn't really support services, so We'll use this image to create a Kubernetes deployment. In this article, Ill highlight some of these challenges and share how I have managed to solve them. Would the reflected sun's radiation melt ice in LEO? 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. external load balancer. 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). Backstage collects all of those (and more) into a single UI. Make sure to create the appropriate DNS entry in your infrastructure. Use kind to create a Kubernetes cluster to work with. The codebase is divided up into differentfeatures, each owned and maintained by a separate team. Kubernetes nodes. The object definitions might look familiar, since This file contains definitions for two different kinds, separated by a line with The template spec shows one container, created from the expected by PostgreSQL. How can I change a sentence based upon input to a command? mapping translates normal HTTP port 80 to the backend http port (7007) on the A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. Encryption at Rest In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. 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. Deployments in Kubernetes are commonly assigned to their own For storing secrets in Git, consider Now that the image is loaded, we can create a Backstage deployment and a service to expose it on an IP inside the cluster. 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. Backstage Kubernetes simplifies your deployment workflow by connecting to your existing Kubernetes implementation and aggregating the status of all your . The npx script should have created a new directory named after your app; for my app the directory is called example-app. To do that: To enable it you need to provide a valid email address in the chart's values: By default, the charts use letsencrypt-staging so in the above example we instruct helm to use the production issuer Thank you for taking the time to read my post, I really appreciate it. Be sure to enable Backstage Software Catalog and Developer Platform Edit Deploying with Kubernetes Kubernetes is a system for deploying, scaling and managing containerized applications. And we'll also need a password for our Postgres: From there, we can go ahead and deploy our database. This tutorial uses version 0.3.7 of the Backstage CLI to create this application. 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. Research, Following a pull request from review to production, Review performance of your teams mobile features. This is generally done with a Kubernetes Backstage is designed to fit this model and run as a stateless application with an external PostgreSQL database. Everything connected with Tech & Code. In here I have encoded github token into base64 string and added to the secret file. Following is the deployment to create Kubernets namespace. Following is the deployment of Postgres. 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. pod port. 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. 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. Thats Backstage. also uses the Kubernetes For any Backstage configuration secrets, such as authorization tokens, we can It is simpler and quicker to get set up with Backstage and Sqlite3. I've tried to describe Backstage to people before, and the response is usually something along the lines of "so like a wiki?" 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. Kubernetes is a system for deploying, scaling and I have encoded Postgres username/password information into Kubernets Secret(username/password added as base64 encoded values). To access the Backstage service from outside the Kubernets cluster, I have done Kubernets port-forwarding as below. For a list of trademarks of The Linux Foundation, please see our Trademark Usage page: https://www.linuxfoundation.org/trademark-usage, 5. Does Cast a Spell make you a spellcaster? provider. You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. 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 a production setup you'll want to try to trim that down a bit using something like multi-stage builds. This means that uninstalling and re-installing the charts with postgres.enabled set to true and claims can ask for only part of a volume as well. This creates 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." 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. However, over the past few weeks it's come up in conversation with engineers whose opinions I respect, In this senario I have created Backstage app and published it on git repository along with Kubernets deployments. 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. We created Backstage about four years ago. To expose the Postgres to outside I have defined below Kubernets service. Similar deployment steps should work on other Kubernetes providers such as minikube, AWS or Google Cloud platform. To isolate the database Unfortunately, at the moment there aren't any guides on getting a Backstage app deployed anywhere besides your laptop in the official documentation. 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). I was feeling inspired, so I went with "example-app" for the name. 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. During CI, a beautiful-looking documentation site is created usingMkDocs, and all sites are rendered centrally in a Backstage plugin.
