Intro

Go template is a powerful tool to generate text output. It is used in many places, such as Kubernetes, Helm, and so on.

To see the details of Go template, please refer to the official document: https://pkg.go.dev/text/template.

Use examples with mugo

With mugo we can use directly giveing values on commandline to run simple templates.

mugo -s -d '{"name": "mugo"}' - <<< "{{.name}}"

Or we write template and stop stdin with ctrl+d.

mugo -d '{"name": "mugo"}' -

But for more complex templates files are better option for now.

This is a values.yaml file

name: mugo

And this is our template file name.tpl

{{ .name }}

To run with mugo

mugo -s -d @values.yaml -t @name.tpl
#mugo

Log output is move to stderr and template output is moved to stdout.

When we redirect to file, we use redirection or -o flag.

mugo -d @values.yaml name.tpl -o name.txt

mugo -d @values.yaml name.tpl > name.txt
