Ansible: To use the 'ssh' connection type with passwords, you must install the sshpass program"

Question

Recently I created new roles called spd in my existing project. While other script works fine in the setup. This newly created fails. Please point me to what is going wrong here

ansible/roles
      spd
        tasks
        templates
        defaults

deploy-spd.yml

 - hosts:
   roles:
     - spd

inventory file

[kube-master]
kubernetes-master-1 ansible_host=10.20.0.225 ansible_user=centos ansible_become=true
kubernetes-master-2 ansible_host=10.20.0.226 ansible_user=centos ansible_become=true
kubernetes-master-3 ansible_host=10.20.0.227 ansible_user=centos ansible_become=true

Failure

bash-4.3# ansible-playbook -i inventory/inventory deploy-test-ms.yml --ask-vault-pass
Vault password:

Answer 1

For centOS, use sudo yum install sshpass

Answer 2

It is the host machine which needs the sshpass program installed. Again, this error message of:

ERROR! to use the 'ssh' connection type with passwords, you must install the sshpass program

Applies to the HOST (provisioner) not the GUEST (machine(s) being provisioned). Thus install sshpass on the provisioner.

Install sshpass on Ubuntu 16.04 or similar

apt-get install sshpass

Install sshpass on Mac OS

brew install hudochenkov/sshpass/sshpass

Source: How to install sshpass on Mac?

Answer 3

in your client machine install sshpass. Ubuntu: sudo apt install sshpass CentOs: yum install sshpass

Answer 4

brew install hudochenkov/sshpass/sshpass

this path seem ok

Answer 5

Just to add to various answers above and this method directly resolves and answers the main issue as stated in the title.

It is possible to pass the parameter using paramiko, which is another pure python implementation of SSH. This is supported by ansible and would be the preferred option as it relies on less cross language dependancies that has to be separately managed; Thus this essentially by-passes the need for another library installed on your host machine : sshpass.

instead of using the connection ssh as below :

$ansible-playbook -i hosts -v -b -c ssh --ask-pass myplaybook.yml

you can and will find it easier to use the following :

$ansible-playbook -i hosts -v -b -c paramiko --ask-pass myplaybook.yml

if you are interested, you can read more here: http://www.paramiko.org/

thanks for additional comments as mention, via the paramiko way, you can also set it in your inventory file, or set it as a playbook option.

Answer 6

for MacOS brew install sshpass resolved this issue for me

Answer 7

For macOS

brew install esolitos/ipa/sshpass

To quickly verify I would just ping

ansible all -i path/to/host -m ping

Answer 8

For UBUNTU

sudo apt install sshpass

After this run ansible script

Answer 9

Use ansible_password to ansible_pass and that will do it!

Answer 10

The issue was because of use of attribute ansible_password in /defaults/main.yml. I have maintained lots of variables in this file to be used by script along with attribute ansible_password.

- include_vars: "{{ role_path}}/defaults/main.yml"

The attribute ansible_password is reserved for use by Ansible. Now I changed the variable name to ansible_pass and it is working fine.
