# k8s-podinfo
Podinfo is a tiny web application made with Go
that showcases best practices of running microservices in Kubernetes.
Specifications:
* Release automation (Make/TravisCI/CircleCI/Quay.io/Google Cloud Container Builder/Skaffold/Weave Flux)
* Multi-platform Docker image (amd64/arm/arm64/ppc64le/s390x)
* Health checks (readiness and liveness)
* Graceful shutdown on interrupt signals
* File watcher for secrets and configmaps
* Instrumented with Prometheus
* Tracing with Istio and Jaeger
* Structured logging with zap
* 12-factor app with viper
* Fault injection (random errors and latency)
* Helm chart
Web API:
* `GET /` prints runtime information
* `GET /version` prints podinfo version and git commit hash
* `GET /metrics` return HTTP requests duration and Go runtime metrics
* `GET /healthz` used by Kubernetes liveness probe
* `GET /readyz` used by Kubernetes readiness probe
* `POST /readyz/enable` signals the Kubernetes LB that this instance is ready to receive traffic
* `POST /readyz/disable` signals the Kubernetes LB to stop sending requests to this instance
* `GET /status/{code}` returns the status code
* `GET /panic` crashes the process with exit code 255
* `POST /echo` forwards the call to the backend service and echos the posted content
* `GET /env` returns the environment variables as a JSON array
* `GET /headers` returns a JSON with the request HTTP headers
* `GET /delay/{seconds}` waits for the specified period
* `POST /token` issues a JWT token valid for one minute `JWT=$(curl -sd 'anon' podinfo:9898/token | jq -r .token)`
* `GET /token/validate` validates the JWT token `curl -H "Authorization: Bearer $JWT" podinfo:9898/token/validate`
* `GET /configs` returns a JSON with configmaps and/or secrets mounted in the `config` volume
* `POST /store` writes the posted content to disk at /data/hash and returns the SHA1 hash of the content
* `GET /store/{hash}` returns the content of the file /data/hash if exists
* `GET /ws/echo` echos content via websockets `podcli ws ws://localhost:9898/ws/echo`
* `GET /chunked/{seconds}` uses `transfer-encoding` type `chunked` to give a partial response and then waits for the specified period

# Ambassador
Ambassador is an open source, Kubernetes-native [microservices API gateway](https://www.getambassador.io/about/microservices-api-gateways) built on the [Envoy Proxy](https://www.envoyproxy.io/).
## TL;DR;
```console
$ helm install stable/ambassador
```
## Introduction
This chart bootstraps an [Ambassador](https://www.getambassador.io) deployment on
a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
## Prerequisites
- Kubernetes 1.7+
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install --name my-release stable/ambassador
```
The command deploys Ambassador API gateway on the Kubernetes cluster in the default configuration.
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 --purge 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 Ambassador chart and their default values.
| Parameter | Description | Default |
| ------------------------------- | ------------------------------------------ | ---------------------------------------------------------- |
| `image` | Image | `quay.io/datawire/ambassador`
| `imageTag` | Image tag | `0.29.0`
| `imagePullPolicy` | Image pull policy | `IfNotPresent`
| `replicaCount` | Number of Ambassador replicas | `1`
| `resources` | CPU/memory resource requests/limits | None
| `rbac.create` | If `true`, create and use RBAC resources | `true`
| `serviceAccount.create` | If `true`, create a new service account | `true`
| `serviceAccount.name` | Service account to be used | `ambassador`
| `service.type` | Service type to be used | `LoadBalancer`
| `adminService.create` | If `true`, create a service for Ambassador's admin UI | `true`
| `adminService.type` | Ambassador's admin service type to be used | `ClusterIP`
| `exporter.image` | Prometheus exporter image | `datawire/prom-statsd-exporter:0.6.0`
| `timing.restart` | The minimum number of seconds between Envoy restarts | `15`
| `timing.drain` | The number of seconds that the Envoy will wait for open connections to drain on a restart | `5`
| `timing.shutdown` | The number of seconds that Ambassador will wait for the old Envoy to clean up and exit on a restart | `10`

# Weave Cloud Grafana
Grafana v5 with Kubernetes dashboards and Prometheus and Weave Cloud data sources.
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install stable/grafana --name my-release \
--set service.type=NodePort \
--set token=WEAVE-TOKEN \
--set password=admin
```
The command deploys Grafana 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 --purge 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 Grafana chart and their default values.
Parameter | Description | Default
--- | --- | ---
`image.repository` | Image repository | `grafana/grafana`
`image.pullPolicy` | Image pull policy | `IfNotPresent`
`image.tag` | Image tag | `5.0.1`
`replicaCount` | desired number of pods | `1`
`resources` | pod resources | `none`
`tolerations` | List of node taints to tolerate | `[]`
`affinity` | node/pod affinities | `node`
`nodeSelector` | node labels for pod assignment | `{}`
`service.type` | type of service | `LoadBalancer`
`url` | Prometheus URL, used when Weave token is empty | `http://prometheus:9090`
`token` | Weave Cloud token | `none`
`user` | Grafana admin username | `admin`
`password` | Grafana admin password | `none`
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install stable/grafana --name my-release \
--set=token=WEAVE-TOKEN \
--set password=admin
```
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```console
$ helm install stable/grafana --name my-release -f values.yaml
```
> **Tip**: You can use the default [values.yaml](values.yaml)
```

# Ngrok
Expose Kubernetes service with [Ngrok](https://ngrok.com).
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install sp/ngrok --name my-release \
--set token=NGROK-TOKEN \
--set expose.service=podinfo:9898
```
The command deploys Ngrok 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 --purge 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 Grafana chart and their default values.
Parameter | Description | Default
--- | --- | ---
`image.repository` | Image repository | `stefanprodan/ngrok`
`image.pullPolicy` | Image pull policy | `IfNotPresent`
`image.tag` | Image tag | `latest`
`replicaCount` | desired number of pods | `1`
`tolerations` | List of node taints to tolerate | `[]`
`affinity` | node/pod affinities | `node`
`nodeSelector` | node labels for pod assignment | `{}`
`service.type` | type of service | `ClusterIP`
`token` | Ngrok auth token | `none`
`expose.service` | Service address to be exposed as in `service-name:port` | `none`
`subdomain` | Ngrok subdomain | `none`
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm upgrade --install --wait tunel \
--set token=NGROK-TOKEN \
--set service.type=NodePort \
--set expose.service=podinfo:9898 \
sp/ngrok
```
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```console
$ helm install sp/grafana --name my-release -f values.yaml
```
> **Tip**: You can use the default [values.yaml](values.yaml)
```

# Podinfo Istio
Podinfo is a tiny web application made with Go
that showcases best practices of running microservices in Kubernetes.
## Installing the Chart
Create an Istio enabled namespace:
```console
kubectl create namespace demo
kubectl label namespace demo istio-injection=enabled
```
Create an Istio Gateway in the `istio-system` namespace named `public-gateway`:
```yaml
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: public-gateway
namespace: istio-system
spec:
selector:
istio: ingressgateway
servers:
- port:
number: 80
name: http
protocol: HTTP
hosts:
- "*"
tls:
httpsRedirect: true
- port:
number: 443
name: https
protocol: HTTPS
hosts:
- "*"
tls:
mode: SIMPLE
privateKey: /etc/istio/ingressgateway-certs/tls.key
serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
```
Create the `frontend` release by specifying the external domain name:
```console
helm upgrade frontend --install ./charts/podinfo-istio \
--namespace=demo \
--set host=podinfo.example.com \
--set gateway.name=public-gateway \
--set gateway.create=false \
-f ./charts/podinfo-istio/frontend.yaml
```
Create the `backend` release:
```console
helm upgrade backend --install ./charts/podinfo-istio \
--namespace=demo \
-f ./charts/podinfo-istio/backend.yaml
```
Create the `store` release:
```console
helm upgrade store --install ./charts/podinfo-istio \
--namespace=demo \
-f ./charts/podinfo-istio/store.yaml
```
Start load test:
```console
helm upgrade --install loadtest ./charts/loadtest \
--namespace=loadtesting
```

# Podinfo
Podinfo is a tiny web application made with Go
that showcases best practices of running microservices in Kubernetes.
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm repo add sp https://stefanprodan.github.io/k8s-podinfo
$ helm upgrade my-release --install sp/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 --purge 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 | Description | Default
--- | --- | ---
`affinity` | node/pod affinities | None
`color` | UI color | blue
`backend` | echo backend URL | None
`faults.delay` | random HTTP response delays between 0 and 5 seconds | `false`
`faults.error` | 1/3 chances of a random HTTP response error | `false`
`hpa.enabled` | enables HPA | `false`
`hpa.cpu` | target CPU usage per pod | None
`hpa.memory` | target memory usage per pod | None
`hpa.requests` | target requests per second per pod | None
`hpa.maxReplicas` | maximum pod replicas | `10`
`ingress.hosts` | ingress accepted hostnames | None
`ingress.tls` | ingress TLS configuration | None:
`image.pullPolicy` | image pull policy | `IfNotPresent`
`image.repository` | image repository | `stefanprodan/podinfo`
`image.tag` | image tag | `0.0.1`
`ingress.enabled` | enables ingress | `false`
`ingress.annotations` | ingress annotations | None
`ingress.hosts` | ingress accepted hostnames | None
`ingress.tls` | ingress TLS configuration | None
`message` | UI greetings message | None
`nodeSelector` | node labels for pod assignment | `{}`
`replicaCount` | desired number of pods | `2`
`resources.requests/cpu` | pod CPU request | `1m`
`resources.requests/memory` | pod memory request | `16Mi`
`resources.limits/cpu` | pod CPU limit | None
`resources.limits/memory` | pod memory limit | None
`service.externalPort` | external port for the service | `9898`
`service.internalPort` | internal port for the service | `9898`
`service.nodePort` | node port for the service | `31198`
`service.type` | type of service | `ClusterIP`
`tolerations` | list of node taints to tolerate | `[]`
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install stable/podinfo --name my-release \
--set=image.tag=0.0.2,service.type=NodePort
```
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
```console
$ helm install stable/podinfo --name my-release -f values.yaml
```
> **Tip**: You can use the default [values.yaml](values.yaml)
```
