从 Java 运行 ansible-playbook

Question

I have been trying to run anisble-playbooks using Java (runtime().exec() and ProcessBuilder), and in both instances I see that the extra variables that I wish to pass using the commandline never get executed or so it seems.

ProcessBuilder builder = new ProcessBuilder("ansible-playbook", "/root/playbooks/script-ilo.yml", "-e", "'@/tmp/vars.yml'");

and

String[] ansible_run = {"ansible-playbook", "/root/playbooks/script-ilo.yml", "-e", "'@/tmp/vars.yml'"};
Process p = Runtime.getRuntime().exec(ansible_run,null);

I packed the code as a jar and executed in test system and in both cases, ansible runs the playbook and throws an error.

# java -jar /home/admin/test-script.jar

PLAY [esxi] ********************************************************************

TASK [Gathering Facts] *********************************************************
ok: [192.168.50.100]

TASK [Set XML with new secrets] ************************************************
fatal: [192.168.50.100]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'change_user' is undefined\n\nThe error appears to have been in '/root/playbooks/script-ilo.yml': line 3, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  tasks:\n    - name: Set XML with new secrets\n      ^ here\n"}
        to retry, use: --limit @/root/playbooks/script-ilo.retry

PLAY RECAP *********************************************************************
192.168.50.100             : ok=1    changed=0    unreachable=0    failed=1

When I run the command ansible-playbook /root/playbooks/script-ilo.yml -e '@/tmp/vars.yml' in the shell, it run perfect.

I need help with getting unblocked here. If there is a better way to do this, I am all ears.

String[] ansible_run = {"ansible-playbook", "/root/playbooks/script-ilo.yml", "-e", "'@/tmp/vars.yml'"};

Don't put single quotes in that -e value; the single quotes are only needed for your shell, but ProcessBuilder doesn't go through your shell, so the arguments don't need to be escaped.

I was actually expecting ansible to whine when I fed it a blatantly bogus -e , but it turns out that any such value is passed in to the hostvars as _raw_params , so in your case, it would have set a value like:

"hostvars": {
    "192.168.50.100": {
        "_raw_params": "'@/tmp/vars.yml'",

我遇到了类似的问题并使用以下方法解决了它

ProcessBuilder builder = new ProcessBuilder("ansible-playbook", "/etc/ansible/playbooks_vmware/diskadd1.yaml","-e","vm_name=web04 addSizeInGB=40 scsi=0 unit_number=1");
