Ya'll got any ideas for what you can do with the template package? The code generation tricks seems pretty useful.

[@Aloysius1966]

Reporting. I'd like to build a webApp to query all my various storage arrays and post the metrics to a web page. Like total space, used space, etc. Basically, capacity planning stuff. Cool video. Thanks for posting.

[@DonaldFeury]

Oh that sounds pretty neat. So basically you would run some commands, such as *df* , to grab disk usage info, pass that into a go template and produce a static web page?

[@Aloysius1966]

@@DonaldFeury Exactly! I'd do that with the whole stack: storage, compute (hardware + hypervisor) & networking metrics. I'd call it "Dr Datacenter" .... if i knew how to program :-)

[@DonaldFeury]

Could just learn how to do each piece individually, then finally figure out how combine them. I use that approach to learning all the time.

[@fairclothjm]

I have used it to generate config files for servers, services, etc

Thank ya Tom and oh yes I love that font

Thanks for the walkthrough on templates. I'm looking at doing a project to automate some data center switch syntax.

[@rawriamakittyrawr]

Thank you so much, I finally understand that damn dot

[@DonaldFeury]

I'm glad I cleared that up for someone 😂

[@jijosunny8626]

Thank you , this is a very good intro to templates! Finally, i understood how helm processes its templates :)

[@DonaldFeury]

I have saved another mind from the confusion of templates

[@YBWang-pi9qq]

the part of generating golang code is really cool.

[@Kleinepaps]

Hi, it's been a while since this video, but can you use text/template to generate a yaml file from the combination of an override yaml + the template yaml?

[@redlinenorma1]

Yes, you can. Helm uses go templates exactly for that, for example

[@AneeshKumarUSA]

What is the best way to insert dynamic data in client-side javascript? JS also uses double curly braces. Vs code shows errors, but it compiles and runs. BTW, I am using chart.js for client side charting. Any suggestions?
