# or through external inventory scripts (see online API docs)
# prompted variables are a list of variable names and a description
# that will be presented to the user, or a list of variable dictionaries
# with the following accepted keys / value types:
# 'name' / text
# 'prompt' / text (optional)
# 'private' / boolean (optional)
# prompted variables as key/value pairs:
vars_prompt:
release_version: "product release version"
# prompted variables as a list of variable dictionaries:
# here's basic mode prompting. Specify a hash of variable names and a prompt for
# each.
#
# vars_prompt:
# - name: "some_password"
# prompt: "Enter password: "
# private: True
# - name: "release_version"
# prompt: "Product release version: "
# private: False
# release_version: "product release version"
# prompts can also be specified like this, allowing for hiding the prompt as
# entered. In the future, this may also be used to support crypted variables
vars_prompt:
- name: "some_password"
prompt: "Enter password"
private: True
- name: "release_version"
prompt: "Product release version"
private: False
# this is just a simple example to show that vars_prompt works, but
# you might ask for a tag to use with the git module or perhaps
