OLake-UI

OLake

OLake Go enables real-time data ingestion from databases, S3, and Kafka into Apache Iceberg.
OLake Fusion is a table management system for Apache Iceberg, helping teams to optimize performance and reduce storage costs.

Overview

OLake-UI offers an intuitive web interface to configure, monitor, and manage your data replication jobs.

• API Contracts

Running with Docker Compose

This Docker Compose setup provides a comprehensive environment(OLake UI, Temporal worker, Temporal service, and dependencies) for demonstrating and exploring OLake's capabilities. This is the recommended way to get started for local development or evaluation.

Prerequisites

• Docker installed and running (Docker Desktop recommended for Mac/Windows)
• Docker Compose (comes with Docker Desktop)
• Make sure port 8000 is available, as OLake UI is exposed on that port.

Quick Start

1. One-Command Setup:

   Choose the setup that matches your use case:

   Ingestion only

   curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | docker compose -f - up -d

   Ingestion and Maintenance

   curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | ENABLE_OPTIMIZATION="true" docker compose --profile fusion -f - up -d

2. Access the services:

   • OLake UI: http://localhost:8000
   • Default login: Username: admin, Password: password

Optional Configuration

Custom Admin User:

The stack automatically creates an initial admin user on first startup. To change the default credentials, edit the x-signup-defaults section in docker-compose-v1.yml:

x-signup-defaults:
username: &defaultUsername "your-custom-username"
password: &defaultPassword "your-secure-password"
email: &defaultEmail "[email protected]"

Custom Data Directory:

By default, data is stored in ${PWD}/olake-data directory. To use a different location, edit the x-app-defaults section in docker-compose-v1.yml:

x-app-defaults:
  host_persistence_path: &hostPersistencePath /your/host/path

Make sure the directory exists and is writable.

Encryption Modes:

Configure encryption in docker-compose-v1.yml:

x-encryption:
  # 1. For AWS KMS (starts with 'arn:aws:kms:'):
  key: &encryptionKey "arn:aws:kms:..."
  
  # 2. For local AES-256 (any other non-empty string):
  # key: &encryptionKey "secret-key"  # Auto-hashed to 256-bit key
  
  # 3. For no encryption (not recommended for production):
  # key: &encryptionKey ""

• KMS: Uses AWS Key Management Service for encryption/decryption
• Local: Uses AES-256-GCM with key derived from your passphrase
• Empty: No encryption (for development only)

Troubleshooting

• If there are any file permission error, ensure the host persistence/config directory is writable by Docker.
• For complete logs, use:

  docker-compose logs -f

• For logs specific to a service, use:

  docker compose logs -f <service_name>

Updating OLake UI Version

To update OLake UI to the latest version, use the command for your setup:

Ingestion only

curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | docker compose -f - down && \
curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | docker compose -f - up -d

Ingestion and Maintenance

docker ps -aq --filter name=fusion-cluster \
| xargs -r docker rm -f; \
curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml \
| docker compose --profile fusion -f - down && \
curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml \
| ENABLE_OPTIMIZATION="true" docker compose --profile fusion -f - up -d

Note: Your data and configurations will be preserved as they are stored in persistent volumes and the olake-data directory.

Upgrading from legacy docker-compose.yml

To upgrade from legacy docker-compose.yml that was used before Jan 30th 2026:

curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | docker compose -f - down && \
curl -sSL https://raw.githubusercontent.com/datazip-inc/olake-ui/master/docker-compose-v1.yml | docker compose -f - up -d
