# Runbook

Deploy TKC:

```sh

kubectl apply -f manifests/tkc.yaml

```

Apply Pod Security Policy:

```sh

kubectl apply -f manifests/setup-k8s/psp.yaml

```

Create three namespaces:

```sh

kubectl create ns argocd

kubectl create ns monitoring

kubectl create ns flower-market

```

Deploy secret containing Docker Hub token for image pulls:

```sh

export UN=usernamehere

export PW=passwordhere

export EMAIL=emailhere

kubectl create secret docker-registry docker-creds \

  --namespace kube-system \

  --docker-username=$UN \

  --docker-password=$PW \

  --docker-email=$EMAIL

```

Create reg-cred operator to sync imagepullsecrets across namespaces (because, Docker...)

```sh

kubectl apply -f https://raw.githubusercontent.com/mylesagray/home-cluster-gitops/master/manifests/registry-creds/manifest.yaml

```

Create ClusterPullSecret CR

```sh

kubectl apply -f manifests/setup-k8s/regcred-crd.yaml

```

Define custom metric:

```sh

# Metric for this app is defined at 

# kube-prometheus/vendor/kube-prometheus/kube-prometheus-custom-metrics.libsonnet Lines 12-30

```

Build Prometheus:

```sh

cd kube-prometheus/

./build.sh

```

Deploy Prometheus:

```sh

kubectl apply -f manifests/setup-k8s/prometheus-rbac.yaml

kubectl apply -f kube-prometheus/manifests/setup

kubectl apply -f kube-prometheus/manifests

```

Deploy Application:

```sh

kubectl apply -f manifests/app

```

The HPA algorithm to calculate desired scale is:

```sh

desiredReplicas = ceil[currentReplicas * ( currentMetricValue / desiredMetricValue )]

```
