Constants
exTagsPrefix :: StringSource
The exclusion tag prefix. Instance tags starting with this prefix describe a service provided by the instance. Instances providing the same service at not places on the same node.
standbyPrefix :: StringSource
migrationPrefix :: StringSource
allowMigrationPrefix :: StringSource
locationPrefix :: StringSource
standbyAuto :: StringSource
The tag to be added to nodes that were shutdown by hsqueeze.
autoRepairTagPrefix :: StringSource
Auto-repair tag prefix
autoRepairTagEnabled :: StringSource
autoRepairTagPending :: StringSource
autoRepairTagResult :: StringSource
autoRepairTagSuspended :: StringSource
Predicates
hasStandbyTag :: Node -> BoolSource
Predicate of having a standby tag.
Utility functions
Migration restriction tags
getMigRestrictions :: [String] -> [String] -> Set StringSource
Given the cluster tags extract the migration restrictions from a node tag.
splitAtColons :: String -> Maybe (String, String)Source
migrations :: [String] -> [(String, String)]Source
getRecvMigRestrictions :: [String] -> [String] -> Set StringSource
Given the cluster tags, extract the set of migration restrictions a node is able to receive from its node tags.
Location tags
getLocations :: [String] -> [String] -> Set StringSource
Given the cluster tags, extract the node location tags from the node tags.
