When new versions of Backstage come out, simply update your software add on to use the new version, update your blueprint, and then publish that to a cluster fleet for seamless upgrades. In the majority of cases, the Ingress will rely on an external Load Balancer to accept initial traffic before being routed. to know about in the metadata block. Change into the scaffolded-app-sqlite directory which we just created, and use yarn to run a command which will build the Docker image. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Thanks for contributing an answer to Stack Overflow! Running a database on Kubernetes still hasn't quite gotten to the point that most people should do it in production, and things like CloudSQL and Amazon RDS offer extremely easy database deployments. A Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. I am following the steps exactly in doc Backstage app configured to run with Postgres database, so we need setup Postgres installation first. highly available I have obtained the token and embedded it into Kubernets Secret as below. The secrets can now be applied to the Kubernetes cluster: PostgreSQL needs a persistent volume to store data; we'll create one along with This prevents a problem where kubernetes will attempt to find a new version of the backstage docker image on the network, instead of using the one we loaded onto the cluster earlier. Instead, I use a tag that hopefully makes it extremely clear that this is for use on my laptop. Following is the Backstage Kubernets deployment. and so I thought it might be time to investigate it properly. This cluster has no network access and thus, without setting imagePullPolicy: Never, our deployment would fail. Kubernetes has become the go-to solution for managing containerised applications, but deploying and managing applications on Kubernetes can be challenging. You can create and manage a Deployment by using the Kubernetes command line interface, Kubectl. Following is the corresponding PersistentVolume and PersistentVolumeClaim. You can change that information later by updating your Deployment; Modules 5 and 6 of the bootcamp discuss how you can scale and update your Deployments. When use the standard host build with the frontend bundled and served from the Projective representations of the Lorentz group can't occur in QFT! (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). To update the Kubernetes deployment to a newly published version of your Now that we have a docker image for Backstage, we need somewhere to deploy it. A Kubernetes object is a way to tell the . You may see different results if youre using a different version. Backstage unifies all your infrastructure tooling, services, and documentation with a single, consistent UI. 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. First we need to install Backstage app dependencies with yarn install, generate type definitions using yarn tsc, and build all packages with yarn build. Before we can use it, we have to load it into the cluster. To isolate the database There is also a contrib guide to deploying Backstage with 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. Unlike other CNCF projects, Backstage does not comes with pre-built docker containers to deploy. something more persistent beyond a Kubernetes node. This error happens in the backend when it tries to connect to the configured PostgreSQL database and the specified CA is not correct. Some of these include: These challenges are definitely complex and can take many platform teams months to figure out. contributed guide 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. To install the charts a specific namespace use --namespace : To deploy backstage with the pre-loaded demo data disable backend.demoData: For more customization options take a look at the values.yaml file. backend. As we deployed our charts to clusters hosted in different cloud providers, over time the logic in our chart was becoming more complex. postgres user. What's wrong with my argument? Azure DevOps Services. namespace The backstage Docker image we built previously is not automatically shared with our KIND kubernetes cluster. Phase 3: Ecosystem (later) Everyone's infrastructure stack is different. the default HTTP port 80): If you're using an auth provider, it should also have this This folder contains Helm charts that can easily create a Kubernetes deployment of a demo Backstage app. Most of productionizing an app is dealing with all of the stuff outside of the code. Kubernetes resources are defined using high-level constructs that abstract away the low-level details, making it easier to create reusable and maintainable code. In this module, you'll learn the most common Kubectl commands needed to create Deployments that run your applications on a Kubernetes cluster. We've also Most of the microservices running on our cluster were using the same Kubernetes resources, such as Deployments, Services, and ConfigMaps. What's the difference between a power rail and a signal line? We realize this is an ambitious goal. Our mobile apps are developed by many different teams. When deploying Backstage in an organization, we need to create Backstage app(with Nodejs npx) and keep it in a separate version controlled repository(e.g git) since the customizations need to versioned and tracked. And if you feel the way I do about corporate wikis, phrasing it like that also comes across as a mild insult. The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. Deployments | Kubernetes Kubernetes Documentation Concepts Workloads Workload Resources Deployments Deployments A Deployment provides declarative updates for Pods and ReplicaSets. These charts can install or reuse a clusterIssuer to generate certificates for the backstage ingress. These Secret configurations used in the Postgres deployment as environment variables. 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. Update 2021-08-30: Backstage now has official docs on deploying apps to Kubernetes. provider. live demo site. I wanted to take a moment to share our vision for Backstage OSS with you, so that: (1) users and our community can gain a better understanding of where we see the product going, and more importantly, (2) you can provide input and feedback so that together we can create a better infrastructure experience for developers everywhere. 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. While Spotify has many awesome engineers, not every engineer is well-versed in our chosen cloud-provider tooling. Follow to join our 1M+ monthly readers, A DevOps engineer by profession. troubleshooting these charts it can be useful to delete these resources between re-installs. suggest an improvement. Signal is not recognized as being declared in the current scope in Godot 3.5. . This could be things like logging or monitoring agents. Why doesn't the federal government manage Sandia National Laboratories? Once you've created a Deployment, the Kubernetes The deployment and pod are running in the cluster. address configured for the authentication pop-up to work properly. These charts depend on the nginx-ingress controller being present in the cluster. This should be replaced with a cloud volume, network attached storage, or I have linked a Kubernets service with port 7007 to the Backstage Pod in order to access from the outside. Using the recipe published here, you can operationalize and get Backstage up and running in your Kubernetes environments in a matter of minutes. Once other resources come into play (databases, queueing, etc. Read more about configuring Kubernets with Minikube from here. To work around this, we will have to forward a port inside the cluster, to one on our local machine. instead. What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? 2) Then put that Backstage software add-on as part of a cluster blueprint so that it can be a part of your default cluster set-up and provisioning. a triple dash. 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. Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. I have changed the app name in with below configurations on app-config.yaml. The solution is to make sure that the contents of the configMap that holds the certificate match the CA for the PostgreSQL instance. 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 provides tooling to build Docker images, but can be deployed with or For storing secrets in Git, consider The base64 strings can be generated in command-line as well. 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. kubectl delete pvc data--postgresql-0. auto generated passwords will fail. More likely in a production scenario, you'd want to use a more cluster. You should reference those instead of this post. rather create a Kubernetes Service. 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. 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. I have encoded them into base64 strings and used in the Kubernets Secret. During CI, a beautiful-looking documentation site is created usingMkDocs, and all sites are rendered centrally in a Backstage plugin. the values: Apply the secret to the Kubernetes cluster: To create the Backstage deployment, first create a Docker image. NOTE: this volume also stores the configuration for PostgreSQL which includes things like the password for the Launching the CI/CD and R Collectives and community editing features for How do we deploy the Backstage App in AWS? Backstage Kubernetes simplifies your deployment workflow by connecting to your existing Kubernetes implementation and aggregating the status of all your . By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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 the envFrom and secretRef - this tells Kubernetes to fill environment This follows similar steps as the PostgreSQL deployment. referenced the volume created for the deployment, and given it the mount path 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. We created Backstage about four years ago. We're describing a We decided to release Backstage early so we could collaborate more closely with companies that have a similar problem and that want to provide a better developer experience to their teams. 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. 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. 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). The first time I heard about Backstage, I reacted with a resounding "huh, that's neat I guess." Kubectl uses the Kubernetes API to interact with the cluster. 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." Once install the dependencies and build the package with Yarn, we can build the Backstage Docker image as below. claims can ask for only part of a volume as well. However, over the past few weeks it's come up in conversation with engineers whose opinions I respect, Did you find this blog post helpful and interesting? Please clone the repo and continue the post. Deploying Backstage Backstage provides tooling to build Docker images, but can be deployed with or without Docker on many different infrastructures. 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. the minikube internal Docker registry and then rebuild the image to install For an example app-config.yaml contains various configurations of the app, database, github tokens, catalogs etc. Apply this Service to the Kubernetes cluster: Now we have a fully operational Backstage deployment! pointing to a container registry where built Docker images are hosted. 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. By fostering a vibrant community of . Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. 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. Enter Deployments in Kubernetes are commonly assigned to their own This tutorial uses version 0.3.7 of the Backstage CLI to create this application. A Deployment is responsible for creating and updating instances of your application. 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. from Backstage app deployments, we can create a separate Kubernetes deployment The username is backstage, password is hunter2. You signed in with another tab or window. cluster. For a grand In this post Im gonna discuss about deploying Backstage developer portal with Kubernets. The template spec shows one container, created from the Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. This is covered in the Kind docs. You'll probably want to trim down the Docker image. Some resources created by these charts are meant to survive after upgrades and even after uninstalls. First, create a Kubernetes Deployment descriptor: For production deployments, the image reference will usually be a full URL to It expose port 5432 and bind the service with Postgres pod. Backstage is designed to fit this model and run as a stateless application with an external PostgreSQL database. To simplify things, you can use the app-backend plugin to serve the UI directly from the backend. object format for its entity definition files! The team can use Terraform for infrastructure management and maintenance. Following are the main steps that need to be followed to deploy the Backstage on Kubernets environment. If you don't already have a cluster, create one on your laptop by installing kind and running: While the generated app contains a Dockerfile, it only containerizes the backend, and doesn't work with the app-backend plugin. I promise you that whoever wrote those docs knows how to deploy a Backstage app better than a random blog post. But if youdig deeper, youll find that since the very beginning, Spotify has been known for its agile, autonomous engineering culture. This tool is part of the Node.js installation. traffic to the right place. These are applications that need to be run on every node in the cluster. You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. In a pre-orchestration world, installation scripts would often be used to start applications, but they did not allow recovery from machine failure. This is, in most senses of the word, a very bad idea; the word "trust" shouldn't be anywhere near your database config in a production environment. To do this, we will use the built in port forwarding feature of kubectl. 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. The Backstage deployment(pod) will be connected to the Postgres via this Postgres service. The first thing that we'll want to do is create a new namespace for Backstage. 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). variables in the container with values from the Secret we created. be hosted internally in your infrastructure, or a managed one offered by a cloud I was feeling inspired, so I went with "example-app" for the name. How can I change a sentence based upon input to a command? Deploy your application (using your docker image) using kubectl on GKE. This is done by creating . Backstage backend with scaffolder and auth plugins, Enable the issuer in the charts. Yesterday, we released the open source version ofBackstage, our homegrown developer portal. 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? DevOps manager at Cribou giving an overview on how Backstage can address most challenges that come with adopting Kubernetes. @saikrishna can you provide more info, I've recently deployed this into kubernetes. Following are some different components in the Backstage web. Deployment (one or more instances of an application) that we'd like Kubernetes Open http://localhost:7000 in your browser to check that Backstage is working correctly. Dot product of vector with camera's local positive x-axis? This is generally done with a Kubernetes As before, open http://localhost:7000 in your browser to view Backstage. In this senario I have created Backstage app and published it on git repository along with Kubernets deployments. free up resources. Since it's A workaround is to set appConfig.backend.database.connection.ssl.rejectUnauthorized to false in the chart's values. This syntax is helpful if you want to consolidate related Make sure to create the appropriate DNS entry in your infrastructure. 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 final step for our database is to create the service descriptor: Apply the service to the Kubernetes cluster: Now that we have PostgreSQL up and ready to store data, we can create the SealedSecrets or other solutions.
