Quick start Tutorial

Overriding data

Populate the data in the hierarchy

Now let’s provide some different data further up in our hierarchy, for example, we shall override port to be 8099 in our dev environment.

$ mkdir -p /var/lib/jerakia/environment/dev
$ vim /var/lib/jerakia/environment/dev/apache.yaml

---
port: 8099

Query from the command line

If we run the same query command as before, we expect to get the same output

$ jerakia lookup port --namespace apache

"8080"

Remember that the searchpath gets evaluated from the scope, and since we haven’t provided any scope data there is nothing to match. Let’s repeat this lookup by providing some scope data, in this case, ensuring that the environment is dev

$ jerakia lookup port --namespace apache --metadata environment:dev

"8099"
