● Use a container registry
● Use host port mappings for exposing container ports
● Use a load balancer with health checks
● Configurations are packaged into the container images
● Use persistent volumes for sharing runtime artifacts
● No, cluster discovery
● No, container auto-healing
● No, container auto scaling
