Method Detail

getAliasMap

public static Map<String,String> getAliasMap(boolean refresh)

Return a mapping of aliases to canonical name records. There can be multiple aliases pointing to the same canonical name record.

 alias                  canonical
 env1.rice.kuali.org -> ec2-174-129-109-246.compute-1.amazonaws.com
 

getCanonicalMap

public static com.google.common.collect.BiMap<String,String> getCanonicalMap(boolean refresh)

Return a mapping of canonical name records to aliases. The only canonical name records present in this map are those that contain one (and only one) alias. This allows you to deterministically find the correct alias if you have the canonical name record.

 canonical                                      alias
 ec2-174-129-109-246.compute-1.amazonaws.com -> env1.rice.kuali.org
 

removeAllKeysWithDuplicateValues

protected static <T> void removeAllKeysWithDuplicateValues(Map<?,T> map)

getDuplicateValues

protected static <T> Set<T> getDuplicateValues(Map<?,T> map)

queryProvider

protected static List<org.kuali.common.dns.model.SimpleDnsRecord> queryProvider()

Grab all the DNS records known to this provider

asCNAMEAliasFQDNMap

protected static Map<String,String> asCNAMEAliasFQDNMap(List<org.kuali.common.dns.model.SimpleDnsRecord> records)

Filter the list down to just CNAME records.
Convert the DNS record name into a valid FQDN by appending the domain name.
Convert the DNS record value into a valid FQDN by remove the trailing dot (if there is one)
