Variables and templating

Sometimes static configuration files and templates are not enough to solve the real-life problems we might face. To help overcome those trickier challenges and avoid tedious and error-prone manual work, Takomo supports dynamic templating with Handlebars.

Here's a short guide to Handlebars syntax. For more information, consult the official Handlebars documentation.

System environment variables are exposed via the env variable.

You can pass variables from command line using --var and --var-file options. Both options can be used multiple times. Variables are exposed via var variable.

Each file in the partials directory or its subdirectory can be used as Handlebars partial.

You can use variables in stack and stack group configuration files and stack template files. Each of them has a different set of variables available.
