How to change default namespace

[bobafettfrom]

Hi!
I'm trying to install vespa in kubernetes by this instruction
I installed vespa in vespa namespace, but all componets are trying to use 'default' namespace

How to fix this?

Please follow the steps below:

1. Create a namespace using kubectl.
2. In the config/configmap.yml file, replace all occurrences of default with the namespace you created in step 1.
3. In the hosts.xml file, find default and replace it with the namespace you created in step 4. Important: When executing any kubectl apply command, add the -n <NAMESPACE> flag (replace with the actual name of your namespace).

Example: kubectl apply -n vespa -f xxxxxx ...

@bobafettfrom were you able to resolve this? I have the same issue. I configured correct hostnames with my-custom-namespace in configmap.yml, but I still get:
