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. A Kubernetes Pod is a group of one or more Containers, tied together for the purposes of administration and networking. 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. CDK8S offers a more flexible and extensible approach to managing Kubernetes applications, making it a great tool to consider for your Kubernetes deployment needs. backend. Some resources created by these charts are meant to survive after upgrades and even after uninstalls. Were going to use Sqlite3 for this tutorial. Kubernetes node is spending 5 minutes pulling the image and you're trying to will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. The Deployment instructs Kubernetes Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Can you be more specific? expected by PostgreSQL. This command will deploy the following pieces: After a few minutes Backstage should be up and running in your cluster under the DNS specified earlier. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. It is often sufficient to view log output We apply this change to the cluster with the following command. Our homegrown CI system uses Jenkins under the hood, but Spotify engineers dont need to know that. Why does Jesus turn to the Father to forgive in Luke 23:34? Provide a name for the deployment and the container image to deploy. Thanks for contributing an answer to Stack Overflow! provider. create 1 replica (running instance of PostgreSQL), and to create the replica When a deployment is created, Kubernetes builds pods to host application instances. 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? Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). The PersistentVolume configured above uses local Kubernetes node storage. The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. For storing secrets in Git, consider In our quest to solve the above problem, we recently started using CDK8S. Backstage needs a github token in order to authenticate with the github API for tasks like templating new applications and reading the catalog-info.yaml files it uses to store metadata. 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 . How can the mass of an unstable composite particle become complex? Backstage build with Node.js and Yarn. Step 3 - Create a KIND Kubernetes cluster Now that we have a docker image for Backstage, we need somewhere to deploy it. This could be things like logging or monitoring agents. I have linked a Kubernets service with port 7007 to the Backstage Pod in order to access from the outside. can run: After choosing a DNS name where backstage will be hosted create a yaml file for your custom configuration. report a problem Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. 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. postgres user. Use kind to create a Kubernetes cluster to work with. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. We need some special settings on our cluster so we can configure ingress in the cluster with Nginx. Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. highly available As soon as you submit a pull request to Spotifys GitHub Enterprise, our CI system automatically posts a link to the CI/CD view in Backstage. 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. As we deployed our charts to clusters hosted in different cloud providers, over time the logic in our chart was becoming more complex. 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 The Linux Foundation has registered trademarks and uses trademarks. This error happens in the backend when it tries to connect to the configured PostgreSQL database and the specified CA is not correct. It gets harder for individual engineers to find and use all these distinct tools. I have changed the app name in with below configurations on app-config.yaml. Spotify uses adocs-like-codeapproach. A Kubernetes object is a way to tell the . Or paste the errors as well, Added now in the question can you please check it. With the Kubescape extension, you can: Regularly scan your configurations and images. Following are some different components in the Backstage web. Create the Kubernetes Service descriptor: The selector here is telling the Service which pods to target, and the port You'll want to create a separate database user for Backstage. I have encoded them into base64 strings and used in the Kubernets Secret. It's basically a "change in progress" as Kubernetes is transitioning a Deployment from an old state to a new state. Kubernetes is a system for deploying, scaling and DaemonSets are great for running a single instance of an application on every node in the cluster. This file contains definitions for two different kinds, separated by a line with Backstage is a platform for building developer portals, powered by a centralized service catalog. A deployment allows you to describe an application's life cycle, such as which images to use for the app, the number of pods there should be, and the way in which they should be updated. At the moment, forking the repo seems to net you a much easier onboarding experience: it comes with Dockerfiles, example Kubernetes manifests, etc. 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/. running on the same cluster, Kubernetes will inject POSTGRES_SERVICE_HOST and Making statements based on opinion; back them up with references or personal experience. Read more about these usecases from Spotify Engineering blog. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. While Backstage does share some characteristics with a wiki, saying that it's "like a wiki" doesn't really do the idea justice. suggest an improvement. Some of these include: These challenges are definitely complex and can take many platform teams months to figure out. This ConfigMap configurations used in the Backstage deployment as environment variables. This syntax is helpful if you want to consolidate related Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. Kubernetes nodes. Does Cast a Spell make you a spellcaster? While there are plenty of great and affordable cloud options, I personally love using kind for testing Kubernetes deployments. Once you've created a Deployment, the Kubernetes (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). Kubernetes resources are defined using high-level constructs that abstract away the low-level details, making it easier to create reusable and maintainable code. 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. a single-node Kubernetes cluster on your local machine: Now you can run kubectl commands and have changes applied to the minikube Why did the Soviets not shoot down US spy satellites during the Cold War? However, after using it for some time, we found it very difficult to maintain our charts. NOTE: this volume also stores the configuration for PostgreSQL which includes things like the password for the Now Backstage web can be access via localhost:7007 from host machine. Open an issue in the GitHub repo if you want to 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. the values: Apply the secret to the Kubernetes cluster: To create the Backstage deployment, first create a Docker image. for PostgreSQL, remembering to base64 encode Apply the storage volume and claim to the Kubernetes cluster: Now we can create a Kubernetes Deployment descriptor for the PostgreSQL database Seamlessly see the installation take place without you having to read through installation guides. To learn more, see our tips on writing great answers. Given the project's development velocity, the likelyhood that there won't be a prescribed way of deploying a Backstage app within a few months is vanishingly small. Once you have a running Kubernetes cluster, you can deploy your containerized applications on top of it. The best way to deploy This means that uninstalling and re-installing the charts with postgres.enabled set to true and a triple dash. 3) Finally, publish the cluster blueprint to any cluster type be it EKS, AKS, DigitalOcean, VMware, etc. 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. Note that I'm using Fedora, and networking might work different on, say, Docker for Mac. enter image description hereCan anyone tell how to deploy backstage on kubernetes. By both creating your application instances and keeping them running across Nodes, Kubernetes Deployments provide a fundamentally different approach to application management. . Backstage run on port 7007 inside the Pod. All rights reserved. You can create and manage a Deployment by using the Kubernetes command line interface, Kubectl. is there a chinese version of ex. Backstage requires you to configure a. There are two built in database options, Sqlite and PostgreSQL. Applications need to be packaged into one of the supported container formats in order to be deployed on Kubernetes. CDK8S is a tool with flexibility and extensibility at its heart. Because again, a 1.3 gig Docker image is going to cause headaches when your Backstage can be highly customized with using different configuration and plugins.
