Thank you respectfully. While this is answer is certainly the best approach for downloading a file, the question asked "How can i check the file existence in ansible", not "How can I download a file in ansible".
Good job reading between the lines for what the OP actually wanted, but technically this does not answer the question. This module is part of ansible-core and included in all Ansible installations. I think we need a clear answer on what should happen in this case force: no , no checksum, file exists but differs - either: a force a new download and replace the file with contents at URL b keep the file as is.
So this will lead to change twice every time i execute the tasks. With b it would work out of the box With a i need to put in an additional file exists check what i will do now.
Is anyone making any progress on this? I would love to see this fixed as well, or at least have a work-around. My sad workaround is to do a stat first, and skip the task if the file already exists To check for presence on the target host, an explicit stat task is required I am seeing this too, and it is difficult because I have some code that runs depending on the situation sometimes with 'net access, and sometimes without.
So when the web proxy is down, the code fails because it is trying to download something that is already there and we are upgrading from pre I am going to wrap a complicated check around to make the when: reliable, but it would be nice to make this work! I am currently using vladimir-mencl-eresearch 's workaround using stat but am still curious about a permanent fix. Is anyone working on it? If not, why not? Can I help? Skip to content. Star 51k.

So the playbook has neatly printed all the 5 items without spending much effort in writing the playbook or else imaging writing the same thing 5 times to iterate over each value. As we capture the output from any command using register , similar can be done for loop output.
The only difference is that the results will now be stored in a dictionary, with one dictionary entry for each iteration of the loop rather than just one set of results. For example in the existing playbook I have reduced the number of item to shorten the output and then I will store the output into " loopresult " variable. Then we will print the content of loopresult variable:. For those of you who are familiar with programming languages, the idea of a hash is nothing new.
For those of you who are not familiar, a hash is simply a set of data points identified by a key.
