Upgrade a DNS-controller instance

Upgrade the DNS-controller instance

1. Change to the Aspen Mesh release directory for the new version (the version you want to upgrade to).

2. Compare the new DNS-controller values.yaml file with the old DNS-controller values.yaml file (for the currently installed version):

   $ diff manifests/charts/dns-controller/values.yaml <oldDnsControllerValuesFilename>
   

3. Are there any new fields that are required or that you want to override?

   • Yes:

     • Open the override values file for the DNS-controller instance in a text editor.

     • Copy the fields to the override values file and change their values if you want to override them.

     • Save and close the file.

     • Go to step 4.

   • No:

     • Go to step 4.

4. Upgrade the DNS-controller custom resource definition:

   $ kubectl apply -f manifests/charts/dns-controller/crds
   

5. Are you upgrading a general DNS-controller instance (not a realm-specific DNS-controller instance)?

   • Yes:

     • Upgrade the DNS-controller instance without specifying a realm:

       $ helm upggrade <dnsControllerInstanceName> manifests/charts/dns-controller \
           --namespace <namespaceName> \
           --values <instanceOverrideValuesFilename> \
           --wait
       

   • No:

     • Upgrade the DNS-controller instance and specify its realm:

       $ helm upgrade <dnsControllerInstanceName> manifests/charts/dns-controller \
           --namespace <namespaceName> \
           --values <instanceOverrideValuesFilename> \
           --set realm=<realmName> \
           --wait
