问题 I have a generic webserver role that is using another nginx role to spawn new vservers. webserver/meta/main.yml looks like: allow_duplicates: yes dependencies: - role: nginx name: api vserver frontend_port: "{{ frontend_port }}" domain: "{{ api_domain }}" backend_host: 127.0.0.1 - role: nginx name: portal vserver domain: "{{ portal_domain }}" backend_host: 127.0.0.1 The problem is that these variables are supposed to be defined inside the webserver-role/vars/(test|staging).yml Is seems that

问题 This seems to work, but is it fragile? I want the owner and group in the files command to be set to someguy . I'd expect to be able to use {{ remote_user }} but that doesn't work.

ansible - check if file exists on local machine

阅读更多关于 ansible - check if file exists on *local* machine

问题 I have a situation where I need to check the status of a file on the local machine (the one where I will call ansible-playbook ... ). If a file that is created by the user exists, it needs to be copied over to the remote host(s). If it doesn't exist, then none of the remote hosts need it. I know I've done things like : - name: Check for ~/.blah/config stat: path=/home/ubuntu/.blah/config register: stat_blah_config - name: Do something with blah config shell: ~/do_something_with_config.sh when

Ansible, Juniper CLI commands. Timeout Error?

阅读更多关于 Ansible, Juniper CLI commands. Timeout Error?

I am trying to transfer an automation script I made in Python, to ansible (company request), and I have NEVER worked with ansible before. I have tried the "wait_for:", but I have not gotten that to work either. In the script, I could set dev.timeout=None or whatever I needed. I am finding it hard to figure out where I can do this in ansible. I have tried setting the timeout in the "ansible.cfg" file. But that doesnt work. I can do simple commands, like: cli="show version", or cli="show system firmware". The following is my playbook: - hosts: local roles: - Juniper.junos connection: local

Ansible: Can we run an include playbook Asynchronously?

阅读更多关于 Ansible: Can we run an include playbook Asynchronously?

问题 I'm interested to learn if Ansible can run an included playbook asynchronously? Basically what I'm trying to do is run a task "Fire and forget, check on it later." When I check on it later I also want to send a slack notification with the result. However I've notice the included playbook for slack notification takes a little longer than expected to complete and hence it holds up the rest of the playbook. What I want is to async the included playbook for slack notification so that the current

How to break `with_lines` cycle in Ansible?

阅读更多关于 How to break `with_lines` cycle in Ansible?

I would like to use the following handler with Ansible: - name: force ntp update shell: ntpdate {{item}} with_lines: /etc/ntpd.serverlist But I want it to end execution after the first successful execution (the list contains ntpd servers with which you can attempt to sync. One is enough). How would I do that? That's a very interesting situation you have. I haven't tried this personally, but I wonder if something like this would work: - name: force ntp update shell: ntpdate {{item}} with_lines: /etc/ntpd.serverlist register: ntp_result when: ntp_result is not defined or ntp_result.rc != 0

How to specify a callback when calling ansible via its API? I have a callback plugin database_write.py for ansible 2.0.0.2 that logs into a database when this is run: ansible-playbook -i inventory.txt playbook.yml # callback is fired ok This works ok because in my $PWD i have ansible.cfg with this line: callback_plugins = ./src/callback Now I'm trying to make ansible to execute my playbook and my callback using the python API. I've basically copied what the ansible-playbook cli tool does # based on https://github.com/ansible/ansible/blob/v2.0.0.2-1/lib/ansible/cli/playbook.py pbex =
