- getMigRestrictions :: [String] -> [String] -> Set String

Predicates
hasStandbyTag :: Node -> Bool Source #
Predicate of having a standby tag.
Utility functions
getTags :: String -> [String] -> [String] -> Set String Source #
Htools standard tag extraction. Given a set of cluster tags, take those starting with a specific prefix, strip the prefix and append a colon, and then take those node tags starting with one of those strings.
Migration restriction tags
getMigRestrictions :: [String] -> [String] -> Set String Source #
Given the cluster tags extract the migration restrictions from a node tag.
splitAtColons :: String -> Maybe (String, String) Source #
Maybe split a string on the first single occurence of "::" return the parts before and after.
migrations :: [String] -> [(String, String)] Source #
Get the pairs of allowed migrations from a set of cluster tags.
getRecvMigRestrictions :: [String] -> [String] -> Set String Source #
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 String Source #
Given the cluster tags, extract the node location tags from the node tags.
