In the last blog on Docker, we talked about how we use Docker with Bamboo internally. It went into detail on how we were able to build a customized agent image, which can then be used to run build agents. Docker agents have a couple honorable advantages over configuring build agents manually. Once the docker agent image is created, it can be used to run multiple agents on a single or multiple hosts. We understand that there are many advantages of using Docker bamboo-agents, but we need to be able to implement some orchestration around it. There are many orchestrators like Docker Swarm, Kubernetes and Apache Mesos Every one of them has its own philosophy, use cases and architecture. Rancher is a tool built to simplify Docker orchestration and management.
