If you have a variable like vars: myvar: xxx xxx_var: anothervalue the working Ansible syntax: – debug: msg={{ vars[myvar + ‘_var’] }} will give you the analogue of: – debug: msg={{ xxx_var }}
Reason #1 You are using an older version of Ansible which did not have the module you try to run. How to check it? Open the list of modules module documentation and find the documentation page for your module. Read the header at the top of the page – it usually shows the Ansible version … Read more
It is the host machine which needs the sshpass program installed. For an Ubuntu machine such as 16.04, it’s as simple as apt-get install sshpass. Again, this error message of: ERROR! to use the ‘ssh’ connection type with passwords, you must install the sshpass program Applies to the HOST (provisioner) not the GUEST (machine(s) being … Read more

Second, int and abs do what you’d expect- … Read more
