Install Ansible on Arch Linux and Run Playbooks Locally

Installation is pretty simple….

$ sudo pacman -Sy ansible sshpass

Useful dependencies:

Optional dependencies for ansible
    sshpass: for ssh connections with password
    python2-passlib: crypt values for vars_prompt
    python2-netaddr: for the ipaddr filter
    python2-systemd: log to journal
    python2-pywinrm: connect to Windows machines
    python2-dnspython: for dig lookup
    python2-ovirt-engine-sdk: ovirt support
    python2-boto: aws_s3 module
    python2-jmespath: json_query support

We need sshpass for password-based authentication using Ansible.

Run Ansible Locally

Create an inventory hosts file:

$ sudo vim /etc/ansible/hosts

My one currently has just localhost as the control machine:


You’ll also need to make sure the SSH daemon process is running:

$ sudo systemctl start sshd
$ sudo systemctl enable sshd

Also, because by default SSH uses Host key checking which is not supported by sshpass, we first need to SSH locally so we add our fingerprint to our known_hosts file.

[andy@home-pc ~]$ ssh andy@
The authenticity of host ' (' can't be established.
ECDSA key fingerprint is SHA256:cynRa21eyQcfrYWjn4ajYiT1E7HBVn7mjfnDDsveiUE.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '' (ECDSA) to the list of known hosts.
andy@'s password: 
[andy@home-pc ~]$ exit
Connection to closed.
[andy@home-pc ~]$
[andy@home-pc ~]$ cat .ssh/known_hosts ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBPu9ZWP54Dd5gkCllxGqlYyiwO+ZfHTmCLEJW0K9NR7ThLMxu3yTiQgzjWijN80sEs14U4GHNoc8Qv4DujaVmzU=

Now we can test it works by using the ansible ping module:

[andy@home-pc ~]$ ansible control -m ping -u andy --ask-pass
SSH password: | SUCCESS => {
    "changed": false, 
    "ping": "pong"

Now finally you can run ansible commands locally on your machine.

[andy@home-pc ~]$ ansible control -u andy --ask-pass -a "free -h"
SSH password: | SUCCESS | rc=0 >>
