Getting Started

In case you don't want to spend much time, please run this script and enjoy your coffee:

chmod +x ./cluster.sh
./cluster.sh

Remember to authenticate with GCP before using Terraform:

gcloud auth application-default login

Quick Start

This section provides a very quick start guide to get the application up and running as soon as possible. Please refer to the following sections for more detailed instructions.

Using Terraform for Google Kubernetes Engine (GKE)

1. Set up the Cluster:

If you're deploying the application to GKE, you can use Terraform to automate the setup of your Kubernetes cluster. Navigate to the iac/terraform directory and initialize Terraform:

cd iac/terraform
terraform init

Plan and Apply Configuration:

Generate an execution plan to verify the resources that Terraform will create or modify, and then apply the configuration to set up the cluster:

terraform plan
terraform apply

2. Retrieve Cluster Information:

To interact with your GKE cluster, you'll need to retrieve its configuration. You can view the current cluster configuration with the following command:

cat ~/.kube/config

1-init-cluster.mp4

Ensure your kubectl context is set correctly to manage the cluster.

Manual Deployment to GKE

For a more hands-on deployment process, follow these steps:

1. Deploy Nginx Ingress Controller:

The Nginx Ingress Controller manages external access to services in your Kubernetes cluster. Create a namespace and install the Ingress Controller using Helm:

kubectl create ns nginx-system
kubens nginx-system
helm upgrade --install nginx-ingress ./deployments/nginx-ingress

Please story the Nginx Ingress Controller's IP address, as you'll need it later.

2-init-nginx-ingress-controller.mp4

2. Configure API Key Secret:

Store your environment variables, such as API keys, securely in Kubernetes secrets. Create a namespace for model serving and create a secret from your .env file:

kubectl create ns model-serving
kubens model-serving
kubectl delete secret easyllmops-env 
kubectl create secret generic easyllmops-env --from-env-file=.env -n model-serving
kubectl describe secret easyllmops-env -n model-serving

3-deploy-secret.mp4

3. Grant Permissions:

Kubernetes resources often require specific permissions. Apply the necessary roles and bindings:

cd deployments/infrastructure
kubectl apply -f role.yaml
kubectl apply -f rolebinding.yaml

4-grant-permission.mp4

4. Deploy caching service using Redis:

Now, deploy the semantic caching service using Redis:

cd ./deployments/redis
helm dependency build
helm upgrade --install redis .

5-deploy-redis.mp4

5. Deploy LiteLLM:

Deploy the LiteLLM service:

kubens model-serving
helm upgrade --install litellm ./deployments/litellm

6-deploy-litellm.mp4

6. Deploy the Open WebUI:

Next, Deploy the web UI to your GKE cluster:

cd open-webui
kubectl apply -f ./kubernetes/manifest/base -n model-serving

7-deploy-openwebui.mp4

7. Play around with the Application:

Open browser and navigate to the URL of your GKE cluster (e.g. http://172.0.0.0 in step 1) and add .nip.io to the end of the URL (e.g. http://172.0.0.0.nip.io). You should see the Open WebUI:

Continuous Integration/Continuous Deployment (CI/CD) with Jenkins and Ansible

For automated CI/CD pipelines, use Jenkins and Ansible as follows:

1. Set up Jenkins Server:

First, create a Service Account and assign it the Compute Admin role. Then create a Json key file for the Service Account and store it in the iac/ansible/secrets directory.

Next create a Google Compute Engine instance named "jenkins-server" running Ubuntu 22.04 with a firewall rule allowing traffic on ports 8081 and 50000.

ansible-playbook iac/ansible/deploy_jenkins/create_compute_instance.yaml

Deploy Jenkins on a server by installing prerequisites, pulling a Docker image, and creating a privileged container with access to the Docker socket and exposed ports 8081 and 50000.

ansible-playbook -i iac/ansible/inventory iac/ansible/deploy_jenkins/deploy_jenkins.yaml

9-setup-jenkins-server.mp4

2. Access Jenkins:

To access the Jenkins server through SSH, we need to create a public/private key pair. Run the following command to create a key pair:

ssh-keygen

Open Metadata and copy the ssh-keys value.

10-setup-ssh-key.mp4

We need to find the Jenkins server password to be able to access the server. First, access the Jenkins server:

ssh <USERNAME>:<EXTERNAL_IP>

Then run the following command to get the password:

sudo docker exec -it jenkins-server bash
cat /var/jenkins_home/secrets/initialAdminPassword

11-get-password.mp4

Once Jenkins is deployed, access it via your browser:

http://<EXTERNAL_IP>:8081

12-access-jenkins-server.mp4

3. Install Jenkins Plugins:

Install the following plugins to integrate Jenkins with Docker, Kubernetes, and GKE:

Docker
Docker Pipeline
Kubernetes
Google Kubernetes Engine

After installing the plugins, restart Jenkins.

sudo docker restart jenkins-server

13-install-plugins.mp4

4. Configure Jenkins:

4.1. Add webhooks to your GitHub repository to trigger Jenkins builds.

Go to the GitHub repository and click on Settings. Click on Webhooks and then click on Add Webhook. Enter the URL of your Jenkins server (e.g. http://<EXTERNAL_IP>:8081/github-webhook/). Then click on Let me select individual events and select Let me select individual events. Select Push and Pull Request and click on Add Webhook.

14-add-webhook.mp4

4.2. Add Github repository as a Jenkins source code repository.

Go to Jenkins dashboard and click on New Item. Enter a name for your project (e.g. easy-llmops) and select Multibranch Pipeline. Click on OK. Click on Configure and then click on Add Source. Select GitHub and click on Add. Enter the URL of your GitHub repository (e.g. https://github.com/bmd1905/EasyLLMOps). In the Credentials field, select Add and select Username with password. Enter your GitHub username and password (or use a personal access token). Click on Test Connection and then click on Save.

4.4. Setup Kubernetes credentials.

First, create a Service Account for the Jenkins server to access the GKE cluster. Go to the GCP console and navigate to IAM & Admin > Service Accounts. Create a new service account with the Kubernetes Engine Admin role. Give the service account a name and description. Click on the service account and then click on the Keys tab. Click on Add Key and select JSON as the key type. Click on Create and download the JSON file.

17-add-jenkins-sa.mp4

Then, from Jenkins dashboard, go to Manage Jenkins > Cloud. Click on New cloud. Select Kubernetes. Enter the name of your cluster (e.g. gke-easy-llmops-cluster-1), enter the URL and Certificate from your GKE cluster. In the Kubernetes Namespace, enter the namespace of your cluster (e.g. model-serving). In the Credentialsfield, selectAddand selectGoogle Service Account from private`. Enter your project-id and the path to the JSON file.

18-add-cloud-jenkins.mp4

5. Test the setup:

Push a new commit to your GitHub repository. You should see a new build in Jenkins.

Monitoring with Prometheus and Grafana

1. Create Discord webhook:

First, create a Discord webhook. Go to the Discord website and click on Server Settings. Click on Integrations. Click on Create Webhook. Enter a name for your webhook (e.g. easy-llmops-discord-webhook) and click on Create. Copy the webhook URL.

20-create-discord-token.mp4

2. Configure Helm Repositories

First, we need to add the necessary Helm repositories for Prometheus and Grafana:

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

These commands add the official Prometheus and Grafana Helm repositories and update your local Helm chart information.

3. Install Dependencies

Prometheus requires certain dependencies that can be managed with Helm. Navigate to the monitoring directory and build these dependencies:

helm dependency build ./deployments/monitoring/kube-prometheus-stack

4. Deploy Prometheus

Now, we'll deploy Prometheus and its associated services using Helm:

kubectl create namespace monitoring
helm upgrade --install -f deployments/monitoring/kube-prometheus-stack.expanded.yaml kube-prometheus-stack deployments/monitoring/kube-prometheus-stack -n monitoring

This command does the following:

helm upgrade --install: This will install Prometheus if it doesn't exist, or upgrade it if it does.
-f deployments/monitoring/kube-prometheus-stack.expanded.yaml: This specifies a custom values file for configuration.
kube-prometheus-stack: This is the release name for the Helm installation.
deployments/monitoring/kube-prometheus-stack: This is the chart to use for installation.
-n monitoring: This specifies the namespace to install into.

21-start-monitoring-services.mp4

By default, the services are not exposed externally. To access them, you can use port-forwarding:

For Prometheus:

kubectl port-forward -n monitoring svc/kube-prometheus-stack-prometheus 9090:9090

Then access Prometheus at http://localhost:9090

For Grafana:

kubectl port-forward -n monitoring svc/kube-prometheus-stack-grafana 3000:80

Then access Grafana at http://localhost:3000

The default credentials for Grafana are usually:

Username: admin
Password: prom-operator (you should change this immediately)

22-access-prom-graf.mp4

5. Test Alerting

First we need to create a sample alert. Navigate to the monitoring directory and run the following command:

kubectl port-forward -n monitoring svc/alertmanager-operated 9093:9093

Then, in a new terminal, run the following command:

curl -XPOST -H "Content-Type: application/json" -d '[
  {
    "labels": {
      "alertname": "DiskSpaceLow",
      "severity": "critical",
      "instance": "server02",
      "job": "node_exporter",
      "mountpoint": "/data"
    },
    "annotations": {
      "summary": "Disk space critically low",
      "description": "Server02 has only 5% free disk space on /data volume"
    },
    "startsAt": "2023-09-01T12:00:00Z",
    "generatorURL": "http://prometheus.example.com/graph?g0.expr=node_filesystem_free_bytes+%2F+node_filesystem_size_bytes+%2A+100+%3C+5"
  },
  {
    "labels": {
      "alertname": "HighMemoryUsage",
      "severity": "warning",
      "instance": "server03",
      "job": "node_exporter"
    },
    "annotations": {
      "summary": "High memory usage detected",
      "description": "Server03 is using over 90% of its available memory"
    },
    "startsAt": "2023-09-01T12:05:00Z",
    "generatorURL": "http://prometheus.example.com/graph?g0.expr=node_memory_MemAvailable_bytes+%2F+node_memory_MemTotal_bytes+%2A+100+%3C+10"
  }
]' http://localhost:9093/api/v2/alerts

This command creates a sample alert. You can verify that the alert was created by running the following command:

curl http://localhost:9093/api/v2/status

Or, you can manually check the Discord channel.

23-test-alert.mp4

This setup provides comprehensive monitoring capabilities for your Kubernetes cluster. With Prometheus collecting metrics and Grafana visualizing them, you can effectively track performance, set up alerts for potential issues, and gain valuable insights into your infrastructure and applications.

Logging with Filebeat + Logstash + Elasticsearch + Kibana

Centralized logging is essential for monitoring and troubleshooting applications deployed on Kubernetes. This section guides you through setting up an ELK stack (Elasticsearch, Logstash, Kibana) with Filebeat for logging your GKE cluster.

0. Quick run

You can use this single helmfile script to kick off the ELK stack:

cd deployments/ELK
helmfile sync

1. Install ELK Stack with Helm

We will use Helm to deploy the ELK stack components:

Elasticsearch: Stores the logs.
Logstash: Processes and filters the logs.
Kibana: Provides a web UI for visualizing and searching logs.
Filebeat: Collects logs from your pods and forwards them to Logstash.

First, create a namespace for the logging components:

kubectl create ns logging
kubens logging

Next, install Elasticsearch:

helm install elk-elasticsearch elastic/elasticsearch -f deployments/ELK/elastic.expanded.yaml --namespace logging --create-namespace

Wait for Elasticsearch to be ready:

echo "Waiting for Elasticsearch to be ready..."
kubectl wait --for=condition=ready pod -l app=elasticsearch-master --timeout=300s

Create a secret for Logstash to access Elasticsearch:

kubectl create secret generic logstash-elasticsearch-credentials \
  --from-literal=username=elastic \
  --from-literal=password=$(kubectl get secrets --namespace=logging elasticsearch-master-credentials -ojsonpath='{.data.password}' | base64 -d)

Install Kibana:

helm install elk-kibana elastic/kibana -f deployments/ELK/kibana.expanded.yaml

Install Logstash:

helm install elk-logstash elastic/logstash -f deployments/ELK/logstash.expanded.yaml

Install Filebeat:

helm install elk-filebeat elastic/filebeat -f deployments/ELK/filebeat.expanded.yaml

24-deploy-elk.mp4

2. Access Kibana:

Expose Kibana using a service and access it through your browser:

kubectl port-forward -n logging svc/elk-kibana-kibana 5601:5601

Please use this script to get the Kibana password:

kubectl get secrets --namespace=logging elasticsearch-master-credentials -ojsonpath='{.data.password}' | base64 -d

Open your browser and navigate to http://localhost:5601.

3. Verify Log Collection

You should now be able to see logs from your Kubernetes pods in Kibana. You can create dashboards and visualizations to analyze your logs and gain insights into your application's behavior.

25-access-kibana.mp4

Optimize Cluster with Cast AI

Please go to Cast AI to sign up for a free account and get the TOKEN.

Then run this line to connect to GKE:

curl -H "Authorization: Token <TOKEN>" "https://api.cast.ai/v1/agent.yaml?provider=gke" | kubectl apply -f -

Hit I ran this script on Cast AI's UI, then copy the configuration code and paste it into the terminal:

CASTAI_API_TOKEN=<API_TOKEN> CASTAI_CLUSTER_ID=<CASTAI_CLUSTER_ID> CLUSTER_NAME=easy-llmops-gke INSTALL_AUTOSCALER=true INSTALL_POD_PINNER=true INSTALL_SECURITY_AGENT=true LOCATION=asia-southeast1-b PROJECT_ID=easy-llmops /bin/bash -c "$(curl -fsSL 'https://api.cast.ai/v1/scripts/gke/onboarding.sh')"

Hit I ran this script again and waite for the installation to complete.

Then you can see your dashboards on Cast AI's UI:

It's time to optimize your cluster with Cast AI! Go go the Available savings seaction and click Rebalance button.
