os.Getenv
Syntax
os.Getenv VARIABLE ⟼ string
Alias
getenv
Examples:
{{ os.Getenv "HOME" }} → /home/victor
{{ os.Getenv "USER" }} → victor
You can pass values when building your site:
MY_VAR1=foo MY_VAR2=bar hugo
OR
export MY_VAR1=foo
export MY_VAR2=bar
hugo
And then retrieve the values within a template:
{{ os.Getenv "MY_VAR1" }} → foo
{{ os.Getenv "MY_VAR2" }} → bar
With Hugo v0.91.0 and later, you must explicitly allow access to environment variables. For details, review Hugo’s Security Policy. By default, environment variables beginning with HUGO_
are allowed when using the os.Getenv
function.
