It remains possible to override the current release namespace by setting the `namespace` value though this may lead to having the helm metadata and the pulsar components in different namespaces Fixes #66 ### Motivation Trying to deploy the chart in a namespace using the usual helm pattern fails for example ``` kubectl create ns pulsartest helm upgrade --install pulsar -n pulsartest apache/pulsar Error: namespaces "pulsar" not found ``` fixing that while keeping the helm metadata and the deployed objects in the same namespace requires declaring the namespace twice ``` kubectl create ns pulsartest helm upgrade --install pulsar -n pulsartest apache/pulsar --set namespace=pulsartest Error: namespaces "pulsar" not found ``` This is needlessly confusing for newcomers who follow the helm documentation and is contrary to helm best practices. ### Modifications I changed the chart to use the context namespace `.Release.Namespace` by default while preserving the ability to override that by explicitly providing a namespace on the commande line, with the this modification both examples behave as expected ### Verifying this change - [x] Make sure that the change passes the CI checks.
