Allocation Tags

By default, DuploCloud spreads the container replicas across the hosts. By virtue of allocation tag the user can pin a container to a set of hosts that have a specific tag. Click on the edit icon next to allocation tag under host.
AllocationTags as key is already pre-populated, configure the value of your choice for example highmemory;highcpu or serviceA and click on save on the left. Then, when creating a service, set the allocation tag value to be a substring of the above tag, for example highmemory or serviceA. The allocation algorithm tries to pick a host where AllocationTag specified in the service is a substring of the AllocationTags of the host.
