end

#k8s_include(path) ⇒ Object

k8s include directive

For example, <%= k8s_include(‘base/namespace’) %> in manifest file will include ‘base/namespace.yml’ file.

The path is relative to the current (sometimes partial) manifest file.

def k8s_include(path)
  ERB.new(File.read(Pathname(@_curr_file).dirname + (path + '.yml'))).result(binding)
end

#k8s_node(key) ⇒ Object

return node_yaml value for the key.

For example, command execution:

$ kerby build --node_yaml staging-node.yml manifest.yml

and stageing-node.yml contains:

app:
  namespace:  city-A

Then, <%= k8s_node(‘app.namespace’) %> in manifest.yml will be generated to ‘city-A’.
