# Podinfo Podinfo is a tiny web application made with Go that showcases best practices of running microservices in Kubernetes. Podinfo is used by CNCF projects like [Flux](https://github.com/fluxcd/flux2) and [Flagger](https://github.com/fluxcd/flagger) for end-to-end testing and workshops. ## Installing the Chart The Podinfo charts are published to [GitHub Container Registry](https://github.com/stefanprodan/podinfo/pkgs/container/charts%2Fpodinfo) and signed with [Cosign](https://github.com/sigstore/cosign) & GitHub Actions OIDC. To install the chart with the release name `my-release` from GHCR: ```console $ helm upgrade -i my-release oci://ghcr.io/stefanprodan/charts/podinfo ``` To verify a chart with Cosign: ```console $ cosign verify ghcr.io/stefanprodan/charts/podinfo:<VERSION> ``` Alternatively, you can install the chart from GitHub pages: ```console $ helm repo add podinfo https://stefanprodan.github.io/podinfo $ helm upgrade -i my-release podinfo/podinfo ``` The command deploys podinfo on the Kubernetes cluster in the default namespace. The [configuration](#configuration) section lists the parameters that can be configured during installation. ## Uninstalling the Chart To uninstall/delete the `my-release` deployment: ```console $ helm delete my-release ``` The command removes all the Kubernetes components associated with the chart and deletes the release. ## Configuration The following tables lists the configurable parameters of the podinfo chart and their default values. | Parameter | Default | Description | | --------------------------------- | ---------------------- | ---------------------------------------------------------------------------------------------------------------------- | | `replicaCount` | `1` | Desired number of pods | | `logLevel` | `info` | Log level: `debug`, `info`, `warn`, `error` | | `backend` | `None` | Echo backend URL | | `backends` | `[]` | Array of echo backend URLs | | `cache` | `None` | Redis address in the format `tcp://<host>:<port>` | | `redis.enabled` | `false` | Create Redis deployment for caching purposes | | `ui.color` | `#34577c` | UI color | | `ui.message` | `None` | UI greetings message | | `ui.logo` | `None` | UI logo | | `faults.delay` | `false` | Random HTTP response delays between 0 and 5 seconds | | `faults.error` | `false` | 1/3 chances of a random HTTP response error | | `faults.unhealthy` | `false` | When set, the healthy state is never reached | | `faults.unready` | `false` | When set, the ready state is never reached | | `faults.testFail` | `false` | When set, a helm test is included which always fails | | `faults.testTimeout` | `false` | When set, a helm test is included which always times out | | `image.repository` | `stefanprodan/podinfo` | Image repository | | `image.tag` | `<VERSION>` | Image tag | | `image.pullPolicy` | `IfNotPresent` | Image pull policy | | `service.enabled` | `true` | Create a Kubernetes Service, should be disabled when using [Flagger](https://flagger.app) | | `service.type` | `ClusterIP` | Type of the Kubernetes Service | | `service.metricsPort` | `9797` | Prometheus metrics endpoint port | | `service.httpPort` | `9898` | Container HTTP port | | `service.externalPort` | `9898` | ClusterIP HTTP port | | `service.grpcPort` | `9999` | ClusterIP gPRC port | | `service.grpcService` | `podinfo` | gPRC service name | | `service.nodePort` | `31198` | NodePort for the HTTP endpoint | | `h2c.enabled` | `false` | Allow upgrading to h2c (non-TLS version of HTTP/2) | | `extraEnvs` | `[]` | Extra environment variables for the podinfo container | | `config.path` | `""` | config file path | | `config.name` | `""` | config file name | | `extraArgs` | `[]` | Additional command line arguments to pass to podinfo container | | `hpa.enabled` | `false` | Enables the Kubernetes HPA | | `hpa.maxReplicas` | `10` | Maximum amount of pods | | `hpa.cpu` |
