+# Podinfo signed releases
+
+Podinfo deployment manifests are published to GitHub Container Registry as OCI artifacts
+and are signed using [cosign](https://github.com/sigstore/cosign).
+
+## Verify the artifacts with cosign
+
+Install the [cosign](https://github.com/sigstore/cosign) CLI:
+
+```sh
+brew install sigstore/tap/cosign
+```
+
+Verify a podinfo release with cosign CLI:
+
+```sh
+cosign verify -key https://raw.githubusercontent.com/stefanprodan/podinfo/master/cosign/cosign.pub \
+ghcr.io/stefanprodan/podinfo-deploy:latest
+```
+
+## Download the artifacts with crane
+
+Install the [crane](https://github.com/google/go-containerregistry/tree/main/cmd/crane) CLI:
+
+```sh
+brew install crane
+```
+
+Download the podinfo deployment manifests with crane CLI:
+
+```console
+$ crane export ghcr.io/stefanprodan/podinfo-deploy:latest -| tar -xf - 
+
+$ ls -1
+deployment.yaml

+# Podinfo CUE module
+
+This directory contains a [CUE](https://cuelang.org/docs/) module and tooling
+for generating podinfo's Kubernetes resources.
+
+The module contains a `podinfo.#Application` definition which takes `podinfo.#Config` as input.
+
+## Prerequisites
+
+Install CUE with:
+
+```shell
+brew install cue
+```
+
+Generate the Kubernetes API definitions required by this module with:
+
+```shell
+cue get go k8s.io/api/...
+```
+
+## Configuration
+
+Configure the application in `main.cue`:
+
+```cue
+app: podinfo.#Application & {
+	config: {
+		meta: {
+			name:      "podinfo"
+			namespace: "default"
+		}
+		image: tag: "6.1.3"
+		resources: requests: {
+			cpu:    "100m"
+			memory: "16Mi"
+		}
+		hpa: {
+			enabled:     true
+			maxReplicas: 3
+		}
+		ingress: {
+			enabled:   true
+			className: "nginx"
+			host:      "podinfo.example.com"
+			tls:       true
+			annotations: "cert-manager.io/cluster-issuer": "letsencrypt"
+		}
+		serviceMonitor: enabled: true
+	}
+}
+```
+
+## Generate the manifests
+
+```shell
+cue gen
+```

+# Tracing Demo
+
+The directory contains sample [OpenTelemetry Collector](https://github.com/open-telemetry/opentelemetry-collector)
+and [Jaeger](https://www.jaegertracing.io) configurations for a tracing demo.
+
+## Configuration
+
+The provided [docker-compose.yaml](docker-compose.yaml) sets up 4 Containers
+
+1. PodInfo Frontend on port 9898
+2. PodInfo Backend on port 9899
+3. OpenTelemetry Collector listening on port 4317 for GRPC
+4. Jaeger all-in-one listening on multiple ports
+
+## How does it work?
+
+The frontend pods are configured to call onto the backend pods. Both the podinfo
+pods are configured to send traces over to the collector at port 4317 using GRPC.
+The collector forwards all received spans to Jaeger over port 14250 and Jaeger
+exposes a UI over port `16686`.
+
+## Running it locally
+
+1. Start all the Containers
+```shell
+make run
+```
+2. Send some sample requests
+```shell
+curl -v http://localhost:9898/status/200
+curl -X POST -v http://localhost:9898/api/echo
+```
+3. Visit `http://localhost:16686/` to see the spans
+4. Stop all the containers
+```shell
+make stop
+```

Get the application URL by running these commands: https://map[host:podinfo.example.com paths:[map[path:/ pathType:ImplementationSpecific]]] ``` After the change: ``` 1. Get the application URL by running these commands: https://podinfo.example.com/ ``` The changed part is taken as-is from the output of the `helm create` command of Helm version 3.7.1. Tested & working as expected.	2021-11-30 15:32:01 +01:00
