Clustering My webMethods Server Containers
 
Configuring a My webMethods Server Container Cluster
My webMethods Cluster Sample
Although you can create a cluster from My webMethods Server containers manually by running the containers against the same database and using the same JMS provider, the recommended approaches to create a clustered environment are using Docker Compose or Kubernetes.
Certain limitations apply when creating and using clusters from My webMethods Server containers:
*Regardless of the selected approach, you cannot create a hybrid cluster, which is a cluster that includes both My webMethods Server instances, installed on premise regular servers/VMs and instances that run in Docker containers. When adding a new cluster node that runs either in a container or from an on-premise installation, My webMethods Server checks whether the node type matches the cluster type, and shuts down the node if the validation fails.
*You cannot run containers with different My webMethods Server versions in the same cluster.
*You cannot restart or shut down the cluster, or individual cluster members from the Cluster Administration page. Placing a node in maintenance mode from the Cluster Administration page overrides the maintenance configuration from the image or the /MWS/volumes/configs/instance_cfg directory (if available) on container restart.
*When using Kubernetes for clustering, you should define the My webMethods Server using StatefulSet and Ingress objects.
