Overview
Portainer is a centralized multi-cluster management platform that, according to its official site, does the job of the dozen CNCF projects teams would otherwise choose, install, upgrade, and staff. It positions itself as the alternative to assembling sixty open-source projects into a platform, offering one install, one upgrade path, and one lifecycle. Its capabilities include multi-cluster fleet management with centralized governance across Kubernetes clusters on any distribution such as EKS, AKS, GKE, bare metal, or on-premises, and it states that existing Docker and Swarm hosts can join. Portainer also offers managed services through which experienced Kubernetes engineers design, build, and operate a container platform alongside a customer's team.
History
Portainer's official site describes the product as a centralized multi-cluster management platform that performs the job of the dozen CNCF projects teams would otherwise choose, install, upgrade, and staff. It frames the choice as between assembling sixty open-source projects into a platform — which it says teams spend eighteen months on, hire to keep alive, and file under "platform engineering" — and using Portainer, which it presents as one install, one upgrade path, and one lifecycle. The site states that Portainer is for teams that would rather the platform layer were already built, correctly, and governed the same way from one cluster to three thousand edge nodes. It also states that Portainer's managed services team provides experienced Kubernetes engineers who design, build, and operate a customer's container platform with them.
