If it's not already installed you Backstage has a plugin architecture, which means that the UI for different resources (components in Backstage lingo) can be owned by separate teams; 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). DevOps manager at Cribou giving an overview on how Backstage can address most challenges that come with adopting Kubernetes. In the majority of cases, the Ingress will rely on an external Load Balancer to accept initial traffic before being routed. 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. CDK8S offers a more flexible and extensible approach to managing Kubernetes applications, making it a great tool to consider for your Kubernetes deployment needs. Introduction to Backstage (OSS) version. with the given pod template, which again contains Kubernetes metadata and a I have linked a Kubernets service with port 7007 to the Backstage Pod in order to access from the outside. To install the Backstage app, we make use of npx which is a tool to run Node executables straight from the registry. DaemonSets are great for running a single instance of an application on every node in the cluster. For storing secrets in Git, consider I love learning about new technologies and sharing my learning with others. 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. This post marks a very specific point in time of a nascent technology. The base64 strings can be generated in command-line as well. Here we use an image that will run the Nginx web server: kubectl.exe create deployment my-nginx --image nginx. external load balancer. 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. This syntax is helpful if you want to consolidate related run as a stateless application with an external PostgreSQL database. To complete this tutorial, you will need: To run Backstage on Kuberentes, we first need to scaffold a Backstage application to work with. 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. 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. Backstage is designed to fit this model and Our local KIND kubernetes cluster doesnt provide a way to access Backstage from our local machine, which is outside the cluster. In our quest to solve the above problem, we recently started using CDK8S. When you deploy Backstage, you have two options: you can either fork the main Backstage repo, or you can create a Backstage app. Why does Jesus turn to the Father to forgive in Luke 23:34? It expose port 5432 and bind the service with Postgres pod. 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. Deployments in Kubernetes are commonly assigned to their own Backstage can be as simple as a services catalog or as powerful as the UX layer for your entire tech infrastructure. A Kubernetes plugin was recently added. Our homegrown CI system uses Jenkins under the hood, but Spotify engineers dont need to know that. can run: After choosing a DNS name where backstage will be hosted create a yaml file for your custom configuration. Our internal installation of Backstage has over 100 different integrations we call them plugins. 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. Projective representations of the Lorentz group can't occur in QFT! how to create and update instances of your application. it: There is no special wiring needed to access the PostgreSQL service. This should be replaced with a cloud volume, network attached storage, or You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. kubectl delete pvc data--postgresql-0. Some of these include: These challenges are definitely complex and can take many platform teams months to figure out. Some of the key features of Backstage include: enter image description hereCan anyone tell how to deploy backstage on kubernetes. On my laptop it clocked in at around a 1.3G, which is frankly terrible. Launching the CI/CD and R Collectives and community editing features for How do we deploy the Backstage App in AWS? In this case, we're claiming the whole volume - but The basic workflow for this method is to build a Backstage Docker image . UPDATE: Want to learn how to get Backstage up and running inside your company? To get the latest news, deep dives into Backstage features, and a roundup of recent open-source action, sign up for Roadie's Backstage Weekly. ingress or way to deploy to an existing Kubernetes setup is the same way you deploy NOTE: this volume also stores the configuration for PostgreSQL which includes things like the password for the We can double-check that the change was applied successfully by inspecting our backstage Kubernetes pod. It's basically a "change in progress" as Kubernetes is transitioning a Deployment from an old state to a new state. without Docker on many different infrastructures. contributed guide You can use Azure Pipelines to deploy to Azure Kubernetes Service and Kubernetes clusters offered by other cloud providers. To do this, we will use the built in port forwarding feature of kubectl. Now that the image is loaded, we can create a Backstage deployment and a service to expose it on an IP inside the cluster. Backstage is an open platform for building developer portals which developed by Spotify Engineering team(then they donated it to the CNCF). 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. 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. You'll want observability into the system, alerting, etc. Make sure to create the appropriate DNS entry in your infrastructure. It is often sufficient to view log output 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." Please clone the repo and continue the post. Once other resources come into play (databases, queueing, etc. Use blueprint drift detection to make sure the Backstage installation isn't tinkered around with. # Uncomment if health checks are enabled in your app: # https://backstage.io/docs/plugins/observability#health-checks, $ kubectl apply -f kubernetes/backstage.yaml, NAME READY UP-TO-DATE AVAILABLE AGE, NAME READY STATUS RESTARTS AGE, backstage -f backstage-54bfcd6476-n2jkm -c backstage, $ kubectl apply -f kubernetes/backstage-service.yaml. This way you will get notified about my new posts. managing containerized applications. View the GKE Pod logs (Output of your python code) Prerequisites. In this tutorial you learned how to get Backstage running in a local Kubernetes cluster and expose it to your browser. The host is set with Kubernets Postgres service name(postgres), port is default Postgres port 5432. the Backstage software catalog The Kubernetes Service is not exposed for external connections from outside the Note the envFrom and secretRef - this tells Kubernetes to fill environment Visualize your RBAC rules. Would the reflected sun's radiation melt ice in LEO? 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. And we learned a thing or two via the feedback we received. 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? live demo site. Has Microsoft lowered its Windows 11 eligibility criteria? 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). All rights reserved. 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. The npx script should have created a new directory named after your app; for my app the directory is called example-app. Ownership information is automatically captured in our service/software catalog and users can see a list of all the services they own. At Spotify, we deploy software generally by: This method is covered in Building a Docker image and Using the recipe published here, you can operationalize and get Backstage up and running in your Kubernetes environments in a matter of minutes. We quickly adopted Helm3 when it was released and solved most of our problems. and so I thought it might be time to investigate it properly. create a Kubernetes Service for Backstage to handle connecting requests to the for PostgreSQL, remembering to base64 encode Be sure to enable running in a typical cluster. for the cluster. a triple dash. You can find more information about these installations from the Backstage documentations. type of PersistentVolume. Stack Overflow. While Spotify has many awesome engineers, not every engineer is well-versed in our chosen cloud-provider tooling. Hence, I prefer Pulumi over Terraform and CDK8S over Helm. Make sure to create the appropriate DNS entry in your infrastructure. Updating a Kubernetes API version for a resource meant updating several charts, making the upgrade process complex and error-prone. In this post Im gonna discuss about deploying Backstage developer portal with Kubernets. 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. It is simpler and quicker to get set up with Backstage and Sqlite3. postgres user. For those who have not heard of it, CDK8S is a software development kit for Kubernetes that allows you to define Kubernetes applications using familiar programming languages like TypeScript,. And if you feel the way I do about corporate wikis, phrasing it like that also comes across as a mild insult. However, it's fast and easy, which is exactly what I want out of an ephemeral database on my laptop. 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). Once this completes, your kubectl command line utility should be automatically configured to use this newly created cluster. I have run this setup on Minikube-based Kubernets cluster. For testing locally with minikube, you can point the local Docker daemon to 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. 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. Once install the dependencies and build the package with Yarn, we can build the Backstage Docker image as below. One frontend for all your infrastructure. 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. Use this snippet from the KIND docs. highly available We apply this change to the cluster with the following command. Configuring a connection to an existing PostgreSQL instance is possible through the chart's values. Backstage provides tooling to build Docker images, but can be deployed with or then apply the changes with kubectl apply -f kubernetes/backstage.yaml. We should now see that an image has been built successfully. an This is most of the way to a full production deployment of Backstage on The security-minded will notice that I set POSTGRES_HOST_AUTH_METHOD to trust. reveal, you can forward a local port to the service: This shows port 7007 since port-forward doesn't really support services, so So, in the spirit of too much free time on a Saturday, I decided to try to deploy a Backstage app to Kubernetes, Consider a team that wants to deploy something to the cloud. rev2023.3.1.43269. As mentioned above, Backstage need github access token. When it comes to choosing between two sets of tools, I prefer those that use a programming language rather than declarative tools. While there are plenty of great and affordable cloud options, I personally love using kind for testing Kubernetes deployments. 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.) 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). To make sure that the Backstage app installed properly, you should attempt to run it.
