Requirements and prerequisites

Requirements specific to your environment will be covered in the installation process.
Every Portainer release goes through functional, release and post-release testing to ensure it works as expected. Because we cannot test against every configuration variant out there, we test against a subset.
The following tables list all of the configurations that we have tested, validated and consider to be functional. If a variant is not listed, it doesn't mean it won't work, it just means it hasn't been tested.
| Portainer Version | Release Date | Docker Version | Kubernetes Version | Podman Version | Architectures |

If you find an issue with an unlisted configuration, before reporting a bug, update your environment to a valid configuration and try to replicate the issue.
The Portainer Server requires persistent storage in order to maintain the database and configuration information it needs to function. The installation process provides a basic storage configuration for your platform. By default, both Docker and Kubernetes provide local (to the node) storage only, and if cluster-wide persistent storage is desired we recommend implementing it at the infrastructure level (for example, via NFS).
Additionally, you will want to ensure that your persistent storage for Portainer's data volume is right-sized for your needs. If you intend to use Portainer's Git deployment functionality for example, you will need to be aware that as part of the deployment from Git, Portainer will clone the remote repository locally to the Portainer data volume, which in the case of larger or multiple Git repos may consume significant amounts of disk space.
In order to access the UI and API, and for the Portainer Server instance and the Portainer Agents to communicate, certain ports need to be accessible.
On the Portainer Server the following ports must be open:
TCP port 9443 (or 30779 for Kubernetes with NodePort) for the UI and API
TCP port 8000 (or 30776 for Kubernetes with NodePort) for the TCP tunnel server for Edge Agents. This port is optional and only required if using Edge Compute features with Edge Agents.
For the Portainer Agent:
TCP port 9001 (or 30778 for Kubernetes with NodePort) must be accessible on the Agent from the Portainer Server instance.
The Portainer Edge Agent does not require any open ports.
All ports can be changed during installation.
