This collection brings together names from software containerization, including tools and platforms for packaging applications and managing them across computing environments. A container bundles an application with the components it needs while isolating it from other processes, helping the same software run consistently in different settings. The ecosystem spans several roles: Docker is closely associated with building and running containers, while tools such as Nomad focus on scheduling workloads and Portainer on managing container environments. Other names in the collection, including Tectonic, Rocket, Tutum, and Supergiant, are also associated with container platforms or infrastructure management. Together, these examples represent the broader technology landscape around deploying and operating containerized software.
