How to update startup-config after each commit?

CDB and CDB API
1

In my daemon, I was starting session to CDB_RUNNING with flag as 0 whenever user commits configuration. But when I do ‘copy running-config startup-config’, I still see startup-config has default values that I initialized rather than the changed values. Am I missing something or if I need to do anything extra to update the startup-config?

Let’s go with a concrete example to see how to work with the startup datastore. I will go with the intro/1-2-3 example.

First, I have modified the confd.conf file to enable the startup datastore. Following are the changes as compared to the one in the original example:

$ diff confd.conf ../1-2-3-start-query-model/confd.conf
163c163
<       <enabled>true</enabled>
---
>       <enabled>false</enabled>
230c230
<     <enabled>true</enabled>
---
>     <enabled>false</enabled>

Following is a list of NETCONF operations through netconf-console that illustrates how to copy the contents of running to startup after a config leaf value has changed in running:

$ netconf-console --get-config --db running -x dhcp
