I based the installation on Fedora 39 Server Edition.

• Ansible will not work as long as SE Linux is active. Use the cockpit localhost:9090 to disable it for duration you need it to be tured off.
• Don't forget to configure the firewalls correctly. Again, use cockpit.
• Portainer is exported to port 9443. You should use it for coordinating the docker chaos.

You need to scroll though the files and change the values to your setup.

How make a computer ready for ansible

dnf -y install ansible mc net-tools openssh-server openssh-clients passwdqc cracklib-dicts shadow-utils

systemctl enable sshd
systemctl start sshd

useradd -b /specialusers ansibleuser
passwd_value="PUT_A_PASSWORD_HERE"
echo ansibleuser:$passwd_value | chpasswd
echo "ansibleuser ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/ansible

How to make the server ready

Once:

dnf -y install ansible mc net-tools openssh-server openssh-clients passwdqc cracklib-dicts shadow-utils sshpass

ssh-keygen

And then for every computer:

passwd_value="PUT_A_PASSWORD_HERE"
sshpass -p "$passwd_value" ssh-copy-id -o "StrictHostKeyChecking accept-new" ansibleuser@COMPUTERNAME

Overleaf yaml file

For the smtp relay we need to set the email password and email user. You can provide it via command line parameter or yaml file to ansible-playbook.

    EUSER: "SOME EMAIL USER"
    EPASS: "SOME PASSWORD"
