问题 I am using ansible 2.1. I have the following inventory host file and a role being called by a play that needs access to the host file variable. Any thoughts on how to access it (currently getting an error): host file [test1] test-1 ansible_ssh_host=abc.def.ghi.jkl ansible_ssh_port=1212 [test2] test2-1 ansible_ssh_host=abc.def.ghi.mno ansible_ssh_port=1212 [test3] test3-1 ansible_ssh_host=abc.def.ghi.pqr ansible_ssh_port=1212 test3-2 ansible_ssh_host=abc.def.ghi.stu ansible_ssh_port=1212 [all

问题 I'm using Ansible with Jinja2 templates, and this is a scenario that I can't find a solution for in Ansible's documentation or googling around for Jinja2 examples. Here's the logic that I want to achieve in Ansible: if {{ existing_ansible_var }} == "string1" new_ansible_var = "a" else if {{ existing_ansible_var }} == "string2" new_ansible_var = "b" <...> else new_ansible_var = "" I could probably do this by combining several techniques, the variable assignment from here: Set variable in jinja

问题 I have an Ansible playbook for deploying a Java app as an init.d daemon. Being a beginner in both Ansible and Linux I'm having trouble to conditionally execute tasks on a host based on the host's status. Namely I have some hosts having the service already present and running where I want to stop it before doing anything else. And then there might be new hosts, which don't have the service yet. So I can't simply use service: name={{service_name}} state=stopped , because this will fail on new

问题 I met one configuration problem when coding ansible playbook for ssh private key file. As we know, we can define combination with host server, ip & related ssh private key in ansible hosts file for static inventory servers. But i have no idea how to define that with dynamic inventory servers. Ex: --- - hosts: tag_Name_server1 gather_facts: no roles: - role1 - hosts: tag_Name_server2 gather_facts: no roles: - roles2 Below command is used to call that playbook: ansible-playbook test.yml -i ec2

问题 Does anyone have an example of decrypting and uploading a file using ansible-vault. I am thinking about keeping my ssl certificates encrypted in source control. It seems something like the following should work. --- - name: upload ssl crt copy: src=../../vault/encrypted.crt dest=/usr/local/etc/ssl/domain.crt 回答1: That's not going to work. What you will get is your encrypted.crt (with Ansible Vault) uploaded literally as domain.crt What you need to do is make your playbook part of a "Vault"

问题 When I use lineinfile in ansible it is not writing ' , " characters lineinfile: 'dest=/home/xyz state=present line="CACHES="default""' it is giving CACHES=default but the desired output is CACHES="default" How to achieve this? 回答1: it appears you can escape the quotes: - lineinfile: dest=/tmp/xyz state=present line="CACHES=\"default\"" That gives this output: $ cat /tmp/xyz CACHES="default" You don't need to escape single quotes that are inside double quotes: - lineinfile: dest=/tmp/xyz state

问题 The question is simple: what is the difference between ansible_user (former ansible_ssh_user ) and remote_user in Ansible, besides that the first one is set if configuration file and the latter one is set in plays / roles? How do they relate to -u / --user command line options? 回答1: They both seem to be the same. Take a look here: https://github.com/ansible/ansible/blob/c600ab81ee/lib/ansible/playbook/play_context.py#L46-L55 # the magic variable mapping dictionary below is used to translate #

问题 I was trying to use vars_prompt in Ansible with default values taken from facts (or otherwise a previously defined variable). The playbook is intended be used as an ad-hoc one for initial provisioning. My playbook: --- - hosts: server01 gather_facts: True vars_prompt: - name: new_hostname prompt: please enter the name for the target default: "{{ ansible_hostname }}" private: no tasks: - debug: msg="{{ new_hostname }}" Current result: please enter the name for the target [{{ ansible_hostname }
