- The only supported Amazon Aurora config is a PostgreSQL-compatible clustered database with one writer replicating to zero or more readers. Learn more
- PGpool-II is an open-source database solution based on PostgreSQL, providing a proxy between Confluence and a PostgreSQL database cluster. It helps to enhance disaster recovery and ensures the fulfillment of your business continuity planning.
Secret managers
We provide a few secrets management options, as well as to our basic and advanced encryption options and our custom SecretStore implementation.
AWS Secrets Manager
Plaintext
Structured secret
Good to know
See our guide, Configuring Confluence with AWS Secrets Manager, for full details on how to integrate AWS Secrets Manager.
HashiCorp Vault
KV V2 Secrets Engine
Good to know
- KV Secrets Engine V2 is the only version that can be used.
Authenticate with tokens and Kubernetes Service Account Tokens.
- See our guide, Configure Confluence with HashiCorp Vault, for full details on how to integrate HashiCorp Vault.
Java
Oracle JRE/JDK
Java 17
Java 21
Temurin (previously AdoptOpenJDK)
Java 17
Java 21
Known issues:
- We use Temurin to replicate issues raised with OpenJDK. If you’re using a different distribution of OpenJDK we’ll still provide support for our products. However, if the bug is caused by a problem in Java distribution, you'll need to contact the Java distributor for help.
Good to know:
You don't need to install Java if you plan to use the installer to install Confluence, as a Temurin Java 21 JRE is bundled with Confluence.
- See Bundled Tomcat and Java versions to see which Java version was bundled with your Confluence version.
Object storage
S3 object storage
Amazon S3
Good to know:
- Amazon S3 object storage is an optional attachment storage method available to anyone on a Data Center license and running Confluence in AWS.
- If you're a new customer, see S3 object storage for setup instructions.
- If you're an existing customer, you'll need to migrate your attachment data to S3 object storage from the file system or another storage method. See Attachment storage configuration for steps to do this.
- Even if you use S3 object storage, other non-attachment data will still be stored in your home directory.
Infrastructure
Hardware:
- You can't run Confluence on SPARC based hardware. You'll need to use x86 hardware or 64bit derivatives of x86 hardware.
- You can't use an NFS mount for your installation or home directory due to Lucene requirements. If you're installing Confluence Data Center, an NFS mount is fine for the shared home directory, but not for the local home directories.
Containerization
- You can use official images to deploy Confluence in a Docker container, or customize a Docker deployment on your own.
- We support the Atlassian Docker templates and can help with Confluence related problems. We do not provide support for Docker itself or problems with any Docker environment.
Containerization Manager
- You are recommended to use official helm charts to deploy Confluence Data Center using Kubernetes, or customize a Kubernetes deployment on your own with reference to the official helm charts.
- We support the Atlassian Kubernetes helm chart and can help with Confluence Data Center product-related problems. We do not provide support for Kubernetes itself or problems with any Kubernetes environment.
- Read our Kubernetes support disclaimer and more about what we support and what we don’t.
Virtualization:
- You can run Confluence and Confluence Data Center in a virtualized environment (including Docker), but our support team can't assist you with problems related to the environment itself. See Running Confluence in a Virtualized Environment
- Our support team can assist you with deploying Confluence Data Center in AWS using the Cloud Formation Template or Quick Start. We won't be able to assist you if you have significantly customised the Cloud Formation Template.
Application server:
- We only support the Tomcat version that is bundled with your Confluence version. You can't run Confluence in your own application server. See Bundled Tomcat and Java versions to see which version of Tomcat was bundled with your Confluence version.
Internet protocols:
- You can run Confluence in both IPv4 and IPv6 environments.
- Raw IPv6 addresses are not always recognized. See the Confluence 6.9 Upgrade Notes for limitations and known issues.
Operating system support:
- You should only install and use Confluence on operating system versions that have active vendor support. For example, you can use Confluence on any Microsoft supported version of Windows, unless specified otherwise above.
For more information see our Server Hardware Requirements Guide and System Requirements.
