Package org.apache.tomcat.util.digester
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.-
