+# Scrumlr K8s Deployment
+
+## Generate JWT Key
+
+```bash
+openssl ecparam -genkey -name secp521r1 -noout -out $(git rev-parse --show-toplevel)/module3/k8s/kustomize/scrumlr/jwt.key
+```
+
+## Differences in deployment between local minikube cluster and SKE cluster
+
+* Skip PostgreSQL Deployment for SKE deployment, since we use external PostgreSQL
+* Set the right `SCRUMLR_SERVER_DATABASE_URL` value in the scrumlr-backend secret
+* Minikube: Ingress without Host and external-dns/ cert-manager annotations
+* SKE: Ingress with Host and external-dns/ cert-manager annotations
+
+## Deploy Scrumlr into local cluster using minikube
+
+Local Deployment that can run on a lokal K8s cluster like a [minikube](https://minikube.sigs.k8s.io/docs/) cluster.
+As we don't have Postgres as an external service here, we also install Postgres directly in our local cluster.

+# Terraform
+
+## Create service account
+
+* Install CLI tool: https://github.com/stackitcloud/stackit-cli/blob/main/INSTALLATION.md
+* `stackit auth login`
+* `stackit project list`
+* `stackit config set --project-id PROJECTx-IDyy-zzzz-aaaa-DUMMYbbbbbbb`
+* `stackit service-account create --name terraform`
+* `stackit service-account list`
+
+* `stackit service-account key create --email terraform-vsPzcS7@sa.stackit.cloud > sa_key.json`
+* `stackit service-account key list --email terraform-vsPzcS7@sa.stackit.cloud`
+
+* `stackit project member add terraform-vsPzcS7@sa.stackit.cloud --role editor`
+
+## S3 Backend for tfstate
+
+`stackit object-storage enable`
+
+Note: The name must be globally unique. Use only lowercase letters, numbers or hyphens. The name should be at least 3 and at most 63 characters long.
+
+Lets use something kinda random, to have a higher chance of catching an free bucket name:
+
+* `stackit object-storage bucket create tfstate-bucket-g5el`
+* `stackit object-storage credentials-group create --name terraform-state`
+* `stackit object-storage credentials create --credentials-group-id CREDGROU-Pxxx-IDzz-aaaa-DUMMYbbbbbbb`
+
+* `terraform init --backend-config=./config.s3.tfbackend`
+
+Now we can start using Terraform.
+
+## Connect to created SKE cluster
+
+* `stackit ske cluster list`
+* `stackit ske kubeconfig create scrumlr --login`
+* `--login` ensures that authentication is performed with the stackit CLI and very short-lived credentials are used in the background, without this flag the credentials are static and and usually have a longer lifetime. If the credentials are obtained without the `--login` flag, they must be renewed manually.

+# Terraform
+
+## Create service account
+
+* Install CLI tool: https://github.com/stackitcloud/stackit-cli/blob/main/INSTALLATION.md
+* `stackit auth login`
+* `stackit project list`
+* `stackit config set --project-id PROJECTx-IDyy-zzzz-aaaa-DUMMYbbbbbbb`
+* `stackit service-account create --name terraform`
+* `stackit service-account list`
+
+* `stackit service-account key create --email terraform-vsPzcS7@sa.stackit.cloud > sa_key.json`
+* `stackit service-account key list --email terraform-vsPzcS7@sa.stackit.cloud`
+
+* `stackit project member add terraform-vsPzcS7@sa.stackit.cloud --role editor`
+
+## S3 Backend for tfstate
+
+`stackit object-storage enable`
+
+Note: The name must be globally unique. Use only lowercase letters, numbers or hyphens. The name should be at least 3 and at most 63 characters long.
+
+Lets use something kinda random, to have a higher chance of catching an free bucket name:
+
+* `stackit object-storage bucket create tfstate-bucket-g5el`
+* `stackit object-storage credentials-group create --name terraform-state`
+* `stackit object-storage credentials create --credentials-group-id CREDGROU-Pxxx-IDzz-aaaa-DUMMYbbbbbbb`
+
+* `terraform init --backend-config=./config.s3.tfbackend`
+
+Now we can start using Terraform.
+
+## Connect to created SKE cluster
+
+* `stackit ske cluster list`
+* `stackit ske kubeconfig create scrumlr --login`
+* `--login` ensures that authentication is performed with the stackit CLI and very short-lived credentials are used in the background, without this flag the credentials are static and and usually have a longer lifetime. If the credentials are obtained without the `--login` flag, they must be renewed manually.
