[hellt]

fix #2414

let's see if anyone used it

@kaelemc can you give this PR a try with iol? I think the failures are caused by the flakiness in gh actions, because I don't think you used any gomplate templates in the iol template, at lest they don't jump out at me

@hellt I took a look, and both IOL + XRd are generating templates correctly. I do however get this error (both on IOL and XRd)

[kaelemc]

Adding one more thing. The XRd configuration template is broken (n.GenerateConfig(nodeCfg.ResStartupConfig, cfgTemplate)), Looks like the mgmt interface addressing is not being populated.

The template for the script which 'fixes' the management IPv6 addr (to prevent multiple IPv6 addresses on the management interface after redeployments) is working fine.

Wow....
Just look to the size of binaries.

70M before and 36M after removing gomplate.

With gomplate:

Without gomplate:

@kaelemc looks like iol tests are back, and I haven't changed much...

Regarding the xrd I don't think this PR caused any trouble, since the xrd template did not use any of the gomplate functions...

[kaelemc]

@hellt Don't mind me, I was just hallucinating 😆. XRd isn't even supposed to populating mgmt ip in the template config anyways. Looks like all is working well and good 👍
