# 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
|
|
|
|
1. **Check NVIDIA Driver Version**:
|
|
- Ensures NVIDIA drivers are available and compatible.
|
|
|
|
2. **Check Ollama and Open-WebUI Versions (Before Deploy)**:
|
|
- Retrieves the current version of the Ollama and Open-WebUI containers.
|
|
|
|
3. **Deploy with Docker Compose**:
|
|
- Pulls the latest images and recreates the containers using Docker Compose.
|
|
|
|
4. **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:
|
|
```groovy
|
|
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:
|
|
|
|
```sh
|
|
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.
