+# Deploy CodeTrans in a Kubernetes Cluster
+
+This document outlines the deployment process for a Code Translation (CodeTran) application that utilizes the [GenAIComps](https://github.com/opea-project/GenAIComps.git) microservice components on Intel Xeon servers and Gaudi machines.
+
+Please install GMC in your Kubernetes cluster, if you have not already done so, by following the steps in Section "Getting Started" at [GMC Install](https://github.com/opea-project/GenAIInfra/tree/main/microservices-connector/README.md). We will soon publish images to Docker Hub, at which point no builds will be required, further simplifying install.
+
+If you have only Intel Xeon machines you could use the codetrans_xeon.yaml file or if you have a Gaudi cluster you could use codetrans_gaudi.yaml
+In the below example we illustrate on Xeon.
+
+## Required Models
+
+By default, the LLM model is set to a default value as listed below:
+
+|Service  |Model                    |
+|---------|-------------------------|
+|LLM      |mistralai/Mistral-7B-Instruct-v0.3|
+
+Change the `MODEL_ID` in `codetrans_xeon.yaml` for your needs.
+
+## Deploy the RAG application
+
+1. Create the desired namespace if it does not already exist and deploy the application
+
+   ```bash
+   export APP_NAMESPACE=CT
+   kubectl create ns $APP_NAMESPACE
+   sed -i "s|namespace: codetrans|namespace: $APP_NAMESPACE|g"  ./codetrans_xeon.yaml
+   kubectl apply -f ./codetrans_xeon.yaml
+   ```
+
+2. Check if the application is up and ready
+   ```bash
+   kubectl get pods -n $APP_NAMESPACE
+   ```
+
+3. Deploy a client pod for testing
+   ```bash
+   kubectl create deployment client-test -n $APP_NAMESPACE --image=python:3.8.13 -- sleep infinity
+   ```
+
+4. Check that client pod is ready
+   ```bash
+   kubectl get pods -n $APP_NAMESPACE
+   ```
+
+5. Send request to application
+   ```bash
+   export CLIENT_POD=$(kubectl get pod -n $APP_NAMESPACE -l app=client-test -o jsonpath={.items..metadata.name})
+   export accessUrl=$(kubectl get gmc -n $APP_NAMESPACE -o jsonpath="{.items[?(@.metadata.name=='codetrans')].status.accessUrl}")
+   kubectl exec "$CLIENT_POD" -n $APP_NAMESPACE -- curl $accessUrl -X POST -d '{"language_from": "Golang","language_to": "Python","source_code": "package main\n\nimport \"fmt\"\nfunc main() {\n    fmt.Println(\"Hello, World!\");\n}"}' -H 'Content-Type: application/json' > $LOG_PATH/gmc_codetrans.log
+   ```
