Error: in /etc/cni/net.d/87-podman-bridge.conflist: error parsing configuration list: unexpected end of JSON input

[Cédric Jeanneret]

First report here: https://bugzilla.redhat.com/show_bug.cgi?id=1861848

We override the /etc/cni/net.d/87-podman-bridge.conflist with an invalid JSON content in https://opendev.org/openstack/tripleo-ansible/src/branch/master/tripleo_ansible/roles/tripleo_podman/tasks/tripleo_podman_install.yml#L46

This breaks `podman network ls' command (and probably other network related things).

    Ensure we produce a valid JSON while emptying the file

Change abandoned by Emilien Macchi (<email address hidden>) on branch: master
Review: https://review.opendev.org/744046
Reason: podman network ls won't be supported in the context of TripleO, we don't use the CNI networks/bridges, therefore this command won't work.

    Configure the default podman network

    Instead of blanking out the file, we need to configure it. An empty
    file causes the `podman network` to not function and prevents us from
    using containers without --net=host.

    While we don't use this in tripleo today, it is beneficial to not leave
    podman in a broken state on the undercloud or standalone if we actually
    wanted to use podman networking for an external container. This change
    won't remove the network if the interface has been configured and is in
    use as to not break 'podman network'

    It should be noted that the default interface was changed in later
    versions from cni0 to cni-podman0 see podman 3755 (podman > 1.6).
