To append the attribute name with an input variable

Question

I want to append the node attribute name with an input integer value.

Eg:

count=1
node["example_#{count}"]

expected value: node[example_1]

But we are getting a nil value. Please let us know the right way of appending.

Answer 1

there is a different between setting and attribute, and retrieving an attribute.

in the snippet you shared, a node attribute is being retrieved but not assign to any other variable.

if you would like to assign a value to a node attribute, do it as follows:

count = 1
node.default["example_#{count}"] = 'foo'
