Docker in Mattermost Deployments: Updated Recommendations

Starting with Mattermost v10.5, we no longer recommend Docker for production deployments with more than 200 active users. This decision reflects the challenges Docker presents when scaling, maintaining reliability, and ensuring security for larger environments.

We’re focusing our Engineering efforts on deployment methods preferred by mission-critical customers in Defense, Intelligence, Security, and Critical Infrastructure sectors. That said, we recognize Docker’s value for many customers, especially those in the early stages of exploring Mattermost or running smaller-scale installations.

Docker remains a great choice for development, testing, proofs-of-concept (POCs), and production deployments for smaller environments where the benefits outweigh the challenges.

For larger-scale deployments or environments requiring high scalability, reliability, and security, we recommend exploring managed container services like AWS ECS, Azure Container Apps, and Google Cloud Run. These platforms simplify operations with features such as automated scaling, built-in monitoring, seamless upgrades, and enhanced security capabilities.

Why Managed Container Services?

  • Scalability: Simplify scaling as your organization grows without operational complexity.

  • Reliability: Access mission-critical features like load balancing and automated failover to ensure uptime.

  • Maintenance & Updates: Save time on manual updates and infrastructure management, allowing your team to focus on what matters most.

  • Security: Built-in secure updates, secrets management, and role-based access ensure production readiness.

  • Operational Efficiency: Seamless integration with CI/CD workflows, while centralizing logging and performance metrics.

We remain committed to supporting customers in every stage of their Mattermost journey. For deployments under 200 active users, you can continue using Docker with the guidance in our Docker deployment documentation.

For organizations considering infrastructure improvements or preparing for scaling in the future, our team is here to help you transition smoothly to managed container solutions.

We encourage customers to reach out to us with specific needs, questions, or roadblocks with Docker or containerized deployments. Our goal is to ensure that regardless of your deployment method, you’re equipped for success.
