Software and Hardware Requirements
This page outlines the software and hardware requirements for running Kestra.
Software requirements
The table below lists the software requirements for Kestra.
Java Runtime
| Kestra Edition | Required version | Note |
|---|---|---|
| Open Source / Enterprise | >= 21 and < 22 | Default: Java 21 (Eclipse Temurin) |
Queue and Repository
Kestra Open Source supports PostgreSQL or MySQL for the queue and repository components.
Kestra Enterprise Edition (EE) provides two options:
- Use the same JDBC configuration as Open Source for standard deployments
- Use Kafka with Elasticsearch or OpenSearch for large-scale deployments
| Kestra Edition | Database | Required version | Note |
|---|---|---|---|
| OSS / Enterprise | PostgreSQL | >=14 && <= 16.3 | Default latest |
| OSS / Enterprise | MySQL | >= 8 (except version 8.0.31) | Default: 8.3.2 |

| OSS/Enterprise | Google Cloud GCS | N/A | |
| OSS/Enterprise | AWS S3 | N/A | |
| OSS/Enterprise | Azure Blob Storage | N/A |
Hardware requirements
A Kestra standalone server requires at least 4 GiB of memory and 2 vCPUs. To use script tasks, the server must support Docker-in-Docker (this is why, for example, AWS ECS Fargate is not supported).
For guidance on allocating memory and CPU for different architecture components, contact us. We can help size your deployment based on your expected workload.
