Follow-up to this Q&A.

According to this and this documentation it should be possible to define a default vault password file by specifying vault_password_file = ~/.vault_pass.txt in one of the following files:

* ANSIBLE_CONFIG (an environment variable)
* ansible.cfg (in the current directory)
* .ansible.cfg (in the home directory)
* /etc/ansible/ansible.cfg

Although the password file exists and the log indicates that the ansible.cfg is used that contains the definition, the decryption fails:

user@host$
Using /etc/ansible/ansible.cfg as config file
ERROR! Decryption failed on /path/to/ansible/group_vars/production/vault

Discussion

  • Is the pass correct for this vault?

Yes. When ansible is run using --vault-password-file=~/.vault_pass.txt the decryption succeeds.

  • Just so that we're clear - the name of the environment variable is ANSIBLE_VAULT_PASSWORD_FILE, correct?

No. When this variable is used it works, but the aim is to set it in the ansible.cfg by setting /etc/ansible/ansible.cfg.

  • What Ansible version is used?

    user@host:/dir$ ansible --version
    ansible 2.2.2.0
        config file = /etc/ansible/ansible.cfg
        configured module search path = Default w/o overrides
    
  • Does using a full path in the config works?

The decryption failes as well when the full path instead of ~, i.e. /home/user/.vault_pass.txt was specified.

  • And what's the output of echo $ANSIBLE_VAULT_PASSWORD_FILE? – 13dimitar Mar 30 '17 at 10:05
  • it is empty because I try to use vault_password_file = ~/.vault_pass.txt – 030 Mar 30 '17 at 10:08
  • variable names are case sensitive – 13dimitar Mar 30 '17 at 10:16
  • This is set in the ansible.cfg. I am not using an environment variable – 030 Mar 30 '17 at 11:40

It is unclear why it failed, but setting vault_password_file = ~/.vault_pass.txt in /etc/ansible/ansible.cfg was sufficient.

According to the docs,

You can also set ANSIBLE_VAULT_PASSWORD_FILEenvironment variable, e.g. ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass.txtand Ansible will automatically search for the password in that file.

Ensures that you are using the exact same case.

  • You are'missing the question, it is about configuration file property specially, it is stated literally in the question, read it again carefully – Tensibai Apr 2 '17 at 20:58
