Class ServiceBindingPropertySource
java.lang.Object
org.apache.tomcat.util.digester.ServiceBindingPropertySource
- All Implemented Interfaces:
- IntrospectionUtils.PropertySource,- IntrospectionUtils.SecurePropertySource
public class ServiceBindingPropertySource
extends Object
implements IntrospectionUtils.SecurePropertySource
A 
IntrospectionUtils.SecurePropertySource
 that uses Kubernetes service bindings to resolve expressions.
 Usage example:
Configure the certificate with a service binding. When the service binding is constructed as follows:
    $SERVICE_BINDING_ROOT/
                         /custom-certificate/
                                            /keyFile
                                            /file
                                            /chainFile
                                            /keyPassword
 
 
   
     <SSLHostConfig>
           <Certificate certificateKeyFile="${custom-certificate.keyFile}"
                        certificateFile="${custom-certificate.file}"
                        certificateChainFile="${custom-certificate.chainFile}"
                        certificateKeyPassword="${chomp:custom-certificate.keyPassword}"
                        type="RSA" />
     </SSLHostConfig> 
 
 
   The optional chomp: prefix will cause the ServiceBindingPropertySource
   to trim a single newline (\r\n, \r, or \n)
   from the end of the file, if it exists. This is a convenience for hand-edited
   files/values where removing a trailing newline is difficult, and trailing
   whitespace changes the meaning of the value.
 
 
   echo "org.apache.tomcat.util.digester.PROPERTY_SOURCE=org.apache.tomcat.util.digester.ServiceBindingPropertySource" >> conf/catalina.properties
 
 or add this to CATALINA_OPTS
 
 
   -Dorg.apache.tomcat.util.digester.PROPERTY_SOURCE=org.apache.tomcat.util.digester.ServiceBindingPropertySource
 
 NOTE: When configured the PropertySource for resolving expressions
              from system properties is still active.-

getPropertyDescription copied from interface:IntrospectionUtils.SecurePropertySourceObtain a property value, checking that code associated with the provided class loader has permission to access the property. If theclassLoaderisnullor ifclassLoaderdoes not implementPermissionCheckthen the property value will be looked up without a call toPermissionCheck.check(java.security.Permission)- Specified by:
- getPropertyin interface- IntrospectionUtils.SecurePropertySource
- Parameters:
- key- The key of the requested property
- classLoader- The class loader associated with the code that trigger the property lookup
- Returns:
- The property value or nullif it could not be found or ifPermissionCheck.check(java.security.Permission)fails
