About the Cluster Server agents for Docker, Docker Daemon, and Docker Container
The Cluster Server (VCS) agents monitor specific resources within an enterprise application. They determine the status of resources and start or stop them according to external events. The Cluster Server agents for Docker Daemon and Docker Container provide high availability for Docker daemon and Docker containers in a cluster.
The Docker daemon provides the base infrastructure for creating and hosting Docker containers. The Docker Daemon can also perform storage-related operations such as creating volumes, mounting or unmounting file systems, removing volumes and other storage related activities. The Docker Daemon eases deployment of Docker Containers without the need to manually provision storage to containers. But, you can also choose to manually provision storage to Docker Containers.
The Docker Container agent monitors the Docker Container instances while they are online and offline. If the system fails, the agent detects failure and takes the container instances offline. Cluster Server initiates failover to another system in the cluster and the agent brings the container instances online.
