+# Setup Test Environment for CI/CD
+This document outlines the steps to set up a test environment for OPEA CI/CD from scratch. The environment will be used to run tests and ensure code quality before PR merge and Release.
+
+## Install Habana Driver (Gaudi Only)
+1. Driver and software installation
+https://docs.habana.ai/en/latest/Installation_Guide/Driver_Installation.html
+2. Firmware upgrade
+https://docs.habana.ai/en/latest/Installation_Guide/Firmware_Upgrade.html
+
+
+## Install Docker
+```shell
+    sudo apt update
+    sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
+    sudo systemctl enable docker.service
+    sudo systemctl daemon-reload
+    sudo systemctl start docker
+```
+### Troubleshooting Docker Installation
+1. Issue: E: Unable to locate package docker-compose-plugin  
+**solution:** 
+```shell
+    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
+    echo \
+      "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
+      $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+    sudo apt-get update
+    sudo apt-get install -y docker-compose-plugin
+```
+2. Issue: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.45/containers/json": dial unix /var/run/docker.sock: connect: permission denied   
+**solution:**   
+```shell
+    # option1. 
+    sudo usermod -a -G docker xxx  
+    # option2. 
+    sudo chmod 666 /var/run/docker.sock 
+```
+3. Issue: ulimit -n setting. [optional]  
+**solution:**  
+```shell
+    cat << EOF | tee /etc/systemd/system/containerd.service.d/override.conf
+    [Service]
+    LimitNOFILE=infinity
+    EOF
+    sudo systemctl restart containerd.service
+```
+4. Issue: control the maximum number of memory mapped areas that a process can have. [optional]   
+**solution:**  
+```shell
+    echo "vm.max_map_count=262144" | sudo tee -a /etc/sysctl.conf
+    sudo sysctl -p
+    sysctl vm.max_map_count # check 
+```
+
+## Install Conda
+For e2e test env setup. 
+```shell
+    wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+    bash Miniconda3-latest-Linux-x86_64.sh
+```
+
+## Install K8S 
+1. Use kubeadm to setup k8s cluster.
+https://github.com/opea-project/docs/blob/main/guide/installation/k8s_install/k8s_install_kubeadm.md
+2. Install Habana plugins  (Gaudi Only)
+https://docs.habana.ai/en/latest/Installation_Guide/Additional_Installation/Kubernetes_Installation/Intel_Gaudi_Kubernetes_Device_Plugin.html 
+### Some Test Code after Installation
+```shell
+    kubectl get nodes -o wide
+    kubectl get pods -A
+    kubectl get cs
+    kubectl describe node <node_name>
+    kubectl describe pod <pod_name>
+```
+Test for Gaudi: 
+```shell
+cat <<EOF | tee test.yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+   name: habanalabs-gaudi-demo
+spec:
+   template:
+      spec:
+         hostIPC: true
+         restartPolicy: OnFailure
+         containers:
+          - name: habana-ai-base-container
+            image: vault.habana.ai/gaudi-docker/1.21.1/ubuntu24.04/habanalabs/pytorch-installer-2.6.0:latest
+            workingDir: /root
+            command: ["hl-smi"]
+            securityContext:
+               capabilities:
+                  add: ["SYS_NICE"]
+            resources:
+               limits:
+                  habana.ai/gaudi: 1
+EOF
+
+kubectl apply -f test.yaml
+kubectl delete -f test.yaml
+```
+
+## Setup Image Registry for K8S Test
+1. Create a docker image registry.
+```shell
+cat << EOF | tee registry.yaml
+version: 0.1
+log:
+  fields:
+    service: registry
+storage:
+  cache:
+    blobdescriptor: inmemory
+  filesystem:
+    rootdirectory: /var/lib/registry
+  delete:
+    enabled: true
+http:
+  addr: :5000
+  headers:
+    X-Content-Type-Options: [nosniff]
+health:
+  storagedriver:
+    enabled: true
+    interval: 10s
+    threshold: 3
+EOF
+
+cd /scratch-1 # place to store the images
+mkdir local_image_registry && chmod -R 777 local_image_registry
+docker run -d -p 5000:5000 --restart=always --name registry -v /home/sdp/workspace/registry.yaml:/etc/docker/registry/config.yml -v /scratch-1/local_image_registry:/var/lib/registry registry:2
+```
+2. Setup docker registry clean up cron. 
+https://github.com/opea-project/Validation/blob/main/tools/image-registry/cleanup.sh
+3. Setup connection to the local registry.   
+
+For docker: 
+```shell
+cat /etc/docker/daemon.json
+# gaudi: 
+{"runtimes": {"habana": {"path": "/usr/bin/habana-container-runtime", "runtimeArgs": []}}, "default-runtime": "habana", "insecure-registries" : [ "100.83.111.232:5000" ]}
+# xeon: 
+{"insecure-registries": ["100.83.111.232:5000"]}
+
+# restart docker
+sudo systemctl restart docker
+
+# for test
+docker pull opea/chatqna:latest
+docker tag opea/chatqna:latest 100.83.111.232:5000/opea/chatqna:test
+docker push 100.83.111.232:5000/opea/chatqna:test
+```
+For K8S: 
+```shell
+# setup in client side
+cat /etc/containerd/config.toml
+...
+[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
+    [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
+      endpoint = ["https://registry-1.docker.io"]
+    [plugins."io.containerd.grpc.v1.cri".registry.mirrors."100.83.111.232:5000"]
+      endpoint = ["http://100.83.111.232:5000"]
+...
+# restart containerd
+sudo systemctl restart containerd.service
+
+# setup in server side
+cd /etc/containerd
+sudo mkdir -p certs.d/100.83.111.232:5000 
+cd certs.d/100.83.111.232:5000 
+cat << EOF | sudo tee hosts.toml
+server = "http://100.83.111.232:5000"
+[host."http://100.83.111.232:5000"]
+  capabilities = ["pull", "resolve", "push"]
+EOF
+
+# restart containerd
+sudo systemctl restart containerd.service
+
+# for test
+docker pull opea/chatqna:latest
+docker tag opea/chatqna:latest 100.83.111.232:5000/opea/chatqna:test
+docker push 100.83.111.232:5000/opea/chatqna:test
+sudo nerdctl -n k8s.io pull 100.83.111.232:5000/opea/chatqna:test
+```
+4. Setup ENV for CI/CD. 
+```shell
+vi .bashrc
+export OPEA_IMAGE_REPO=100.83.111.232:5000/
+```
+5. Build and push images to the new local registry.
+
+## Setup GHA ENV for CI/CD
+1. Setup self-hosed runner for GHA, follow official steps. 
+2. Setup ENV for GHA. 
+```shell
+vi ~/action_runner/.env
+OPEA_IMAGE_REPO=100.83.111.232:5000/
+```
+3. Start runner with svc. 
+```shell
+sudo ./svc.sh install # use svc.sh instead of run.sh
+sudo ./svc.sh start 
+sudo ./svc.sh status 
+sudo ./svc.sh stop 
+```
+## Setup Action Runner Controller (ARC)
+https://docs.github.com/en/actions/tutorials/quickstart-for-actions-runner-controller  
+For now, we only support use ARC on Xeon K8S cluster.    
+1. Install the ARC
+Make sure you have installed k8s and helm charts in your test machine.   
+```shell
+NAMESPACE="opea-arc-systems"
+helm install arc \
+    --namespace "${NAMESPACE}" \
+    --create-namespace \
+    oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller
+
+helm uninstall arc -n $NAMESPACE
+kubectl delete namespace $NAMESPACE --grace-period=0 --force
+```
+2. Install a runner scale set
+The runner image that we used in CI/CD build by this [dockerfile](https://github.com/opea-project/Validation/blob/main/tools/actions-runner-controller/xeon.dockerfile). 
+And the config setting for the runner scale set can be found in [here](https://github.com/opea-project/Validation/blob/main/tools/actions-runner-controller/xeon.yaml).
+```shell
+RUNNER_SET_NAME="xeon"
+RUNNERS_NAMESPACE="opea-runner-set-c1"
+RUNNER_GROUP="opea-runner-set-1" # before use this name, make sure this group has been created in GHA. 
+GITHUB_CONFIG_URL="https://github.com/opea-project"
+GITHUB_PAT="xxx" # the personal access token for GHA, which has the permission to create runners in the repo.
+helm install "${RUNNER_SET_NAME}" \
+    --namespace "${RUNNERS_NAMESPACE}" \
+    --create-namespace \
+    -f xeon_large.yaml \
+    --set githubConfigUrl="${GITHUB_CONFIG_URL}" \
+    --set githubConfigSecret.github_token="${GITHUB_PAT}" \
+    --set runnerGroup="${RUNNER_GROUP}" \
+    oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set
+```
+**Nodes:**   
+a. Make sure the nodes in the cluster have enough resources to run the runner pods.   
+b. Create the special `RUNNER_GROUP` in GHA, which is used to group the runners.  
+c. Make sure you have set up label for `nodeSelector`, with `kubectl label nodes opea-cicd-spr-0 runner-node=true` and use `kubectl get nodes --show-labels` to check the labels.  
+d. Make sure you have `/data2` for model cache. 
+
+3. Clean up the ARC (If needed)
+```shell
+# clean up runner set
+(
+RUNNER_SET_NAME="xeon"
+RUNNERS_NAMESPACE="opea-runner-set-c1"
+helm uninstall $RUNNER_SET_NAME -n $RUNNERS_NAMESPACE
+kubectl delete namespace $RUNNERS_NAMESPACE --grace-period=0 --force
+)
+# clean up ARC
+(
+NAMESPACE="opea-arc-systems"
+helm uninstall arc -n $NAMESPACE
+kubectl delete namespace $NAMESPACE --grace-period=0 --force
+)
+```
