Portainer, a popular tool for managing containerized applications, has just released its latest version, 2.21, introducing the concept of Long Term Support (LTS) into its product lineup. This LTS release is designed to be the backbone of your critical infrastructure, focusing on solidifying existing features rather than introducing new ones. This strategy ensures that all features from the previous Short Term Support (STS) release, version 2.20, operate smoothly and securely.
One of the first things you'll notice in this new version is the revamped menu structure. This revision aims to simplify navigation, making it easier for newcomers to delve into the world of containerization while also enhancing workflow for experts, especially those working within Kubernetes environments.
Enhanced Performance and Security
On the performance front, Portainer has integrated additional caching and moved more components to the React framework, leading to faster page loading times.
The release also introduces a toggle to enable/disable front-end data caching in Kubernetes, configurable via user accounts, ensuring that essential information is prioritized over less critical data.
Furthermore, Portainer 2.21 brings experimental support for streaming authentication activity and logs to external Security Information and Event Management (SIEM) systems. This feature facilitates compliance and monitoring without the need for dedicated API solutions.
Additionally, various interfaces have added new buttons to refresh image update indicators, providing real-time insights into container status.
Expanded Features and Functionality
This new version also expands the scope of manageable Kubernetes objects with a new UI section for managing cluster roles and bindings. Administrators can now enforce limited access to Kubernetes secrets, strengthening security within the cluster environment.
Portainer 2.21 significantly enhances edge computing capabilities. The new Edge Template feature allows for easy application deployments using predefined or custom templates directly from the UI. A new Edge Administrator role has also been introduced, granting granular control over edge resources without full administrative rights.
A Focus on Security and Compatibility
But Portainer 2.21 isn't just about new features – it also includes updates to third-party binaries and libraries to address security vulnerabilities and enhance performance.
Support for the latest Kubernetes versions ensures compatibility with current and future deployments, and the integration of Helm functionality into the main Application system simplifies Kubernetes operations.
Conclusion
Portainer 2.21 LTS offers significant improvements in stability, performance, and security for your container management platform. With a focus on solidifying existing features, this version provides a solid foundation for mission-critical operations.
New features such as Edge templates, granular access control, and SIEM integration further enhance Portainer's functionality and capabilities. If you are looking for a reliable, stable, and feature-rich container management solution, Portainer 2.21 LTS is the right choice.
