剧本中的 Ansible 保险库具有错误变量“tomcat_password”未定义

Question

I am newbie to ansible. I am trying to perform some deployment task in 142.23.9.23 via help of ansible using jenkins. I am hitting below error FAILED: => {"msg", "The field 'become_pass' has an invalid value. which includes an undefined variable: The error was. 'tomcat_password' is undefined"}.

I am open to new suggestion as well.

Below is the details

Directory

ansible
   |---- group_vars
           |---- MAIN
                  |---- vault.yml
   |---- hosts
           |---- host-details.yml
   |---- roles
   |----- my-playbook.yml

my-playbook.yml

- hosts: app-server
  tasks:
    - name: Print message
      debug: msg="test playbook version ansible_host = {{ ansible_host }}, ansible_ssh_user = {{ansible_ssh_user}}"
  vars_files:
    - group_vars/COMMON/vault.yml

host-details.yml

[app-server]
142.23.9.23 ansible_host=142.23.9.23 ansible_ssh_user=myuser ansible_become=yes ansible_become_user=myuser ansible_become_pass='{{ tomcat_password }}'

ansible-vault edit vault.yml

tomcat_password: password1
jenkins_password: password2

I think you should ensure that you understand how group_vars and host_vars works: https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html

The point here, is that your app-server is a group, not an host, and it seems to not being in the group MAIN nor COMMON. You don't have to force the inclusion of vars from group_vars, adding hosts in the groups is enough.

Your inventory should be more like this:

[app-server]
142.23.9.23 ansible_host=142.23.9.23 ansible_ssh_user=myuser ansible_become=yes ansible_become_user=myuser ansible_become_pass='{{ tomcat_password }}'

[COMMON:children]
app-server

[MAIN:children]
app-server

But anyway, please read carefully how to make an inventory as it will solve most of your problems.
