How to use python interpreter in chef
I am trying to use the chef's python interpreter. Below is my naive attempt that didn't work. What is the correct way to accomplish below in python?
script "install_something" do
interpreter "python"
user "root"
cwd "/tmp"
code <<-EOH
import boto
f = open('test.txt','r')
f.write('adfadf')
f.close()
EOH
not_if {File.exists?("/tmp/test.txt")}
end

EOH
are passed to the interpreter verbatim, that is, including the main indentation. Since indentation is part of python syntax, your script (between <<-EOH
/ EOH
) is not valid python.
The solution in this case is to remove the indentation in the <<-EOH
/ block EOH
.
