flannel

This module installs and configures flannel.

Usage:

include flannel

Or:

class { 'flannel':
  etcd_endpoints => "http://${::fqdn}:2379",
  etcd_prefix    => '/coreos.com/network',
}

Or using certificates:

  class { '::etcd':
    ensure                      => 'latest',
    etcd_name                   => $::hostname,
    # clients
    listen_client_urls          => 'https://0.0.0.0:2379',
    advertise_client_urls       => "https://${::fqdn}:2379",
    # clients ssl
    cert_file                   => "${::settings::ssldir}/certs/${::clientcert}.pem",
    key_file                    => "${::settings::ssldir}/private_keys/${::clientcert}.pem",
    trusted_ca_file             => "${::settings::ssldir}/certs/ca.pem",
    # authorize clients
    client_cert_auth            => true,
    # cluster
    initial_cluster             => $initial_cluster,
    listen_peer_urls            => 'https://0.0.0.0:7001',
    initial_advertise_peer_urls => "https://${::fqdn}:7001",
    # peers ssl
    peer_cert_file              => "${::settings::ssldir}/certs/${::clientcert}.pem",
    peer_key_file               => "${::settings::ssldir}/private_keys/${::clientcert}.pem",
    peer_trusted_ca_file        => "${::settings::ssldir}/certs/ca.pem",
    # authorize peers
    peer_client_cert_auth       => true,
  }

  class { '::flannel':
    ensure         => 'latest',
    etcd_endpoints => "http://${::fqdn}:2379",
    etcd_keyfile   => "${::settings::ssldir}/private_keys/${::clientcert}.pem",
    etcd_certfile  => "${::settings::ssldir}/certs/${::clientcert}.pem",
    etcd_cafile    => "${::settings::ssldir}/certs/ca.pem",
    etcd_prefix    => '/coreos.com/network',
  }

Create the etcd node:

    class { '::flannel::etcd_key':
        network   => '172.16.0.0/16',
        subnetmin => '172.16.100.0',
    }

Journald forward:

The class support a parameter called journald_forward_enable.

This was added because of the PIPE signal that is sent to go programs when systemd-journald dies.

Usage:

  include ::forward_journald
  Class['forward_journald'] -> Class['flannel']
