需要提取或从 ansable playbook 的 stdout_ 线提取或获取值
原标题:Need to extract or capture the value from stdout_lines of ansible playbook
I am looking for help to extract or capture the free MB value from the stdout_lines of an ansible playbook execution and use that value as a criteria to proceed further in the playbook. My task output is : ok: [Host1] => { "changed": false, "invocation": { "module_args": { "commands": [ "show file systems | inc flash:" ], "interval": 1, "match": "all", "retries": 10, "wait_for": null } }, "stdout": [ "* 1707192 (1.6 GB) 603744 (589.6 MB) flash rw flash:" ], "stdout_lines": [ [ "* 1707192 (1.6 GB) 603744 (589.6 MB) flash rw flash:" ] ] } I tried to use - set_fact: my_var: "{{ disk_space.stdout_lines | regex_findall( \b([0-9]{1,4}\.\d+)\s+MB.*flash:$ ) }}" But I always get an empty output: ok: [Host1] => { "ansible_facts": { "my_var": [] }, "changed": false } I would like to capture 589.6 value from the output and assign it to variable to be used in my further play. Best Regards, Praveen

Just answering the regex part of the question. The expression written like this \b([0-9]{1,4}\.\d+)\s+MB.*flash:$ and parsed as ([0-9]{1,4}.d+)s+MB.*flash:$ means "the line must end with flash:, but it ends like with flash:" The solution is simple - add the character just before the dollar sign ([0-9]{1,4}.d+)s+MB.*flash:"$ Not sure if that should be escaped or encoded in any specific way in your case.
