Ansible setup to install XDP-tutorial dependencies

This directory contains an Ansible setup, that installs the needed software package dependencies for the XDP-tutorial. It have been used on the VM image that participants are provided.

Running

To run this ansible setup on your own testlab VM, edit the hosts and update it with the correct VM IP-address. Verify that you can SSH login to the VM with username: fedora and your SSH-key.

The script run-on-hosts.sh can be used to run:

• ansible-playbook -i hosts site.yml

Bootstrapping Fedora

Notice: This trick is ONLY needed first time, on an clean/fresh (VM) image.

For some reason /usr/bin/python were not installed in Fedora 29, which Ansible complains about like this:

$ ansible -i hosts --user=root -m ping all
192.168.122.98 | FAILED! => {
    "changed": false,
    "module_stderr": "Shared connection to 192.168.122.98 closed.\r\n",
    "module_stdout": "/bin/sh: /usr/bin/python: No such file or directory\r\n",
    "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error",
    "rc": 127
}

The packages python and python-dnf needs to be installed. We have added a file:bootstrap-ansible.yml that perform this via ansible, and it need to be run like:

ansible-playbook -i hosts --user=root bootstrap-ansible.yml

Afterwards we can test if the user fedora can run ansible:

$ ansible -i hosts --user fedora -m ping all
192.168.122.98 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
