Using custom images with templating is awkward

[robertglonek]

The cluster node template names are fixed to distroName:distroVersion:aerospikeVersion. As such, if creating a template from a custom image, it is named the same as a template from the standard, discovered image. If one requires to create a cluster using a non-standard image, once, this becomes an issue.

Request: provide an ability to create a cluster as a single flow, skipping template creation, if needed. Or alternative provide an option to custom-name templates and use those custom names. (maybe requiring template create followed by cluster create --template-name xxx type approach). Template names would need to show in template list too.
