![]() ![]() It’s a giant pain in the ass if you need to update the password on many machines.Ī better way is to hash the password once using openssl and store the hashed version of the password in your Ansible playbooks: - name: Set the user's password This might be OK if you’re just updating one machine. Attempting to make the play idempotent, by using update_password: on_create, means that you can no longer update the password using Ansible.The play is not idempotent, since the SHA512 filter will re-hash the password every time you run the play, resetting the password each time the play is run.Storing your passwords in plain text is a bad idea, since anyone who can read your Ansible playbook now knows your password.Storing your passwords in plain text is a bad idea This is a bad practice for a number of reasons. Some Ansible docs suggest storing your passwords in plain text and using the Ansible SHA512 filter to hash the plaintext passwords before passing them to the user module. The password must be passed to Ansible in a hashed password format using one of the hash formats supported by /etc/shadow. That’s all on how to generate an encrypted Linux user’s password for Ansible.The Ansible user: command allows you to add a user to a Linux system with a password. Mutable environment that allows package installation with DNF.įor more information, see the documentation. You may want to try out the Toolbox for a directly Switch to user to confirm encrypted password is working.

Note that the implicit localhost does not match 'all' : provided hosts list is empty, only localhost is available. $ ansible-playbook user_create.yml -user= jkmutai -ask-pass -ask-become-passīECOME password: Password: $6$pTpaEDHweswcO86u$MuAiSx/iHxmV2jSvmNzXQYIz1lYIMCeP5KtmZQn圆mgJVfweP6oC8nMQQ9QeLc821YV50fh6yMzOjUCxY0lIq.Įxecute playbook to create the user. $6$pTpaEDHweswcO86u$MuAiSx/iHxmV2jSvmNzXQYIz1lYIMCeP5KtmZQn圆mgJVfweP6oC8nMQQ9QeLc821YV50fh6yMzOjUCxY0lIq.Ĭreate user creation playbook. $ python3 -c 'import crypt,getpass pw=getpass.getpass() print(crypt.crypt(pw) if (pw=getpass.getpass("Confirm: ")) else exit())' ![]() We can create a user with the encrypted password and confirm we can login with the password generated. ![]() $6$ieMLxPFShvi6rao9$XEAU9ZDvnPtL.sDuSdRi6M79sgD9254b/0wZvftBNvMOjj3pHJBCIe04x2M.JA7gZ7MwpBWat1t4WQDFziZPw1 Testing Encrypted password generated Generate password: $ mkpasswd -method=sha-512 You can also use the mkpasswd utility that is available on most Linux systems to generate a hashed password. $6$4QSwvTfs5ijeRo6V$qAgug/HU1WUe7e/s5c6H0HQDCb4QnOumJ6bgxyykiKgewNTr/ifF5yUBq7taNZ0eJAqrXXXwzvxd9ewgq9XHI0 Generate encrypted password using mkpasswd Generate encrypted password with the command: python -c 'import crypt,getpass pw=getpass.getpass() print(crypt.crypt(pw) if (pw=getpass.getpass("Confirm: ")) else exit())' Then ensure that the Passlib password hashing library is installed: sudo pip install passlib If using Python2, e.g CentOS 7 server, first install pip.
