Unable to create a virtual cluster

[Arpit-yb]

What happened?

vcluster create command itself is failing with the following error -
~ ❯ vcluster create vc-1
17:51:35 info Creating namespace vcluster-vc-1
17:51:36 info Create vcluster vc-1...

This was working earlier, I started hitting this issue after upgrading the version to 0.19.5.

What did you expect to happen?

virtual cluster should have been created successfully

How can we reproduce it (as minimally and precisely as possible)?

1. Install vcluster version 0.19.5
2. run - vcluster create <VC_NAME>

Anything else we need to know?

Thx @Arpit-yb for raising the issue.

Could you please check which version of helm you have installed on the machine where you are issuing vcluster create. The parse error in the last line might indicate that the version might be too old.

[Arpit-yb]

Thx @johannesfrey for taking a look.
The helm version I am using is v3.6.0

[johannesfrey]

Thx! Could you try installing a newer version of Helm (e.g. the latest being v3.14.0) and try vcluster create again.

[Arpit-yb]

Thanks! After updating helm, it started working again.

Thanks! After updating helm, it started working again.

Glad it worked. It looks like {{ contine }} inside go template is supported since go 1.18. Helm started using go 1.18 starting with v3.10.0.
