Ollama and Open-WebUI Docker Setup

This repository provides the necessary configuration files to deploy two Docker services, Ollama and Open-WebUI, using Docker Compose and Jenkins for automated management. These services are deployed on the shark-wrangler node, making use of NVIDIA GPU acceleration for Ollama.

Prerequisites

To get started, ensure you have the following installed and configured:

Docker and Docker Compose
NVIDIA GPU drivers (compatible with the Ollama container)
Jenkins with access to the shark-wrangler node

Services Overview

Ollama

Image: ollama/ollama:latest
Container Name: ollama
Ports: 11434:11434
Environment Variables:
- OLLAMA_LLM_LIBRARY=cuda_v12 for GPU acceleration.
Volumes: Mounts data at /root/.ollama to persist Ollama's state.
Networks: Connected to shared_net.

Open-WebUI

Image: ghcr.io/open-webui/open-webui:dev
Container Name: open-webui
Ports: 3000:8080
Environment Variables:
- OAuth Configuration: Enables login and OAuth features.
- OpenAI API Key: Configured to enable integrations.
- OLLAMA_BASE_URL: Points to the running Ollama instance for interoperability.
Volumes: Mounts data at /app/backend/data to persist WebUI state.
Networks: Connected to shared_net.

Docker Compose Configuration

The Docker Compose configuration deploys the following:

ollama and open-webui services with defined volumes and ports.
shared_net network for container communication.

Jenkinsfile for CI/CD

The Jenkinsfile automates the deployment of Ollama and Open-WebUI services using Docker Compose:

Pipeline Stages

Check NVIDIA Driver Version:
- Ensures NVIDIA drivers are available and compatible.
Check Ollama and Open-WebUI Versions (Before Deploy):
- Retrieves the current version of the Ollama and Open-WebUI containers.
Deploy with Docker Compose:
- Pulls the latest images and recreates the containers using Docker Compose.
Check Ollama and Open-WebUI Versions (After Deploy):
- Ensures that the services are running and updated to the latest version after deployment.

The relevant Jenkinsfile snippet:

pipeline {
    agent {
        node { label 'shark-wrangler' }
    }
    environment {
        DOCKER_HOST = 'unix:///var/run/docker.sock'
    }
    stages {
        stage('Check NVIDIA Driver Version') {
            steps {
                script {
                    catchError(buildResult: 'SUCCESS', stageResult: 'UNSTABLE') {
                        sh 'nvidia-smi --query-gpu=driver_version --format=csv,noheader'
                    }
                }
            }
        }
        stage('Check Ollama and Open-WebUI Versions (Before Deploy)') {
            steps {
                script {
                    catchError(buildResult: 'SUCCESS', stageResult: 'UNSTABLE') {
                        echo 'Checking Ollama version before deploy:'
                        sh 'docker exec -i ollama ollama -v || echo "Ollama check failed"'

                        echo 'Checking Open-WebUI version before deploy:'
                        sh 'docker exec -i open-webui jq -r .version /app/package.json || echo "Open-WebUI check failed"'
                    }
                }
            }
        }
        stage('Deploy with Docker Compose') {
            steps {
                script {
                    sh '''
                      docker pull ollama/ollama
                      docker pull ghcr.io/open-webui/open-webui:main
                      docker compose up -d  --force-recreate
                      '''
                }
            }
        }
        stage('Check Ollama and Open-WebUI Versions (After Deploy)') {
            steps {
                script {
                    catchError(buildResult: 'SUCCESS', stageResult: 'UNSTABLE') {
                        echo 'Checking Ollama version after deploy:'
                        sh 'docker exec -i ollama ollama -v || echo "Ollama check failed"'

                        echo 'Checking Open-WebUI version after deploy:'
                        sh 'docker exec -i open-webui jq -r .version /app/package.json || echo "Open-WebUI check failed"'
                    }
                }
            }
        }
    }
    post {
        always {
            echo 'Pipeline finished.'
        }
    }
}

Usage

To deploy the services, simply use Docker Compose:

docker compose up -d

For automated deployments, you can use Jenkins with the provided Jenkinsfile to ensure the latest versions are deployed and tested.

Notes

Ensure all environment variables are correctly set, particularly the OAuth credentials and OpenAI API key.
Update Docker images regularly to maintain security and access new features.
