Issue: 1. Foreman generates auto sign entry when /provision called first time. (boot loader hit) 2. Once OS is done and call puppet agent run, CSR doesn’t get auto-signed. - stays in ‘pending’ status forever

Cloudera manager uses standard log4j which doesn’t support compression by itself.

PUPPET DELL IDRAC CONTROL

if $::manufacturer == 'Dell Inc.' {
    exec { 'Disable DRAC SNMP':
        command =>; 'racadm config -g cfgOobSnmp -o cfgOobSnmpAgentEnable 0',
        path =>; '/opt/dell/srvadmin/sbin:/bin',
        onlyif =>; '/usr/bin/test `/opt/dell/srvadmin/sbin/racadm getconfig -g cfgOobSnmp -o cfgOobSnmpAgentEnable` -eq 1',
    }
}

Yea, I think onlyif bit is not nice.

GENERATE BACULA CLIENT CERT/KEY PAIR VIA PUPPET

exec {'generate client key file': command => '/usr/bin/openssl genrsa -out /bacula/bacula-client.key 2048;chmod 600 /bacula/bacula-client.key', creates => '/bacula/bacula-client.key', require => Package['bacula-fd'], } exec {'generate client cert file': command => '/usr/bin/openssl req -new -key /bacula/bacula-client.key -x509 -subj "/C=AU/ST=somewhere/L=somewhere/O=something/CN=something" -out /bacula/bacula-client.cert', creates => '/bacula/bacula-client.cert', require => [ Package['bacula-fd'], Exec['generate client key file'], ], } exec {'combine client key and cert files': notify => Service["bacula-fd"], command => '/bin/cat /bacula/bacula-client.key /bacula/bacula-client.cert > /bacula/bacula-client.pem;chmod 600 /bacula/bacula-client.pem', creates => '/bacula/bacula-client.pem', require => [ Package['bacula-fd'], Exec['generate client key file'], Exec['generate client cert file'], ], }

Would be nicer if I can send them to backup location but doesn’t really matter as there’s master key.
