referenced the volume created for the deployment, and given it the mount path 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 Backstage deployment(pod) will be connected to the Postgres via this Postgres service. 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. We can double-check that the change was applied successfully by inspecting our backstage Kubernetes pod. Deployment (one or more instances of an application) that we'd like Kubernetes For an example app-config.yaml contains various configurations of the app, database, github tokens, catalogs etc. 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. as in example? Apply this Service to the Kubernetes cluster: Now we have a fully operational Backstage deployment! In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. Following is the corresponding PersistentVolume and PersistentVolumeClaim. Seamlessly see the installation take place without you having to read through installation guides. This directory should contain a packages directory, which has an app and backend directory. For this example, we'll The application will be able to store data, such as the services in the Backstage catalog, in an in-memory Sqlite3 database. Note that I'm using Fedora, and networking might work different on, say, Docker for Mac. Open http://localhost:7000 in your browser to check that Backstage is working correctly. kubectl delete pvc data--postgresql-0. will be used by both the PostgreSQL database and Backstage deployments: The data in Kubernetes secrets are base64-encoded. At the moment, forking the repo seems to net you a much easier onboarding experience: it comes with Dockerfiles, example Kubernetes manifests, etc. Can the Spiritual Weapon spell be used as cover? 2023 Larder Software Limited. By both creating your application instances and keeping them running across Nodes, Kubernetes Deployments provide a fundamentally different approach to application management. Kubernetes canary deployment is a technique for rolling out new features or changes to a small subset of users or servers before releasing the update to the entire system. Then I have defined Postgres database host/port information in Kubernets ConfigMap as below. The base64 strings can be generated in command-line as well. cluster. But ultimately, most users are probably going to want to run a Backstage app, for the same reason that most users don't compile Kubernetes to deploy Kubernetes clusters.

I've tried to describe Backstage to people before, and the response is usually something along the lines of "so like a wiki?" 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. Kubectl uses the Kubernetes API to interact with the cluster. rev2023.3.1.43269.

How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Configuring a connection to an existing PostgreSQL instance is possible through the chart's values. Because again, a 1.3 gig Docker image is going to cause headaches when your Our local KIND kubernetes cluster doesnt provide a way to access Backstage from our local machine, which is outside the cluster. We've also As we deployed our charts to clusters hosted in different cloud providers, over time the logic in our chart was becoming more complex. then apply the changes with kubectl apply -f kubernetes/backstage.yaml. Here we've requested Kubernetes Backstage is a platform for building developer portals, powered by a centralized service catalog. Thanks for contributing an answer to Stack Overflow! Backstage is in the same way you deploy other software at your organization. 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. 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. Note that app.baseUrl and backend.baseUrl in your app-config.yaml should In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure.
