/bin/bash all the things. Since we are using bash syntax in some of the element fragments, we should make sure we use bash for all of them, so that things don't break on systems where /bin/sh != /bin/bash.

set -e all the things Using set -e in all of our scripts will prevent some subtle bugs from slipping in, and will allow us to enforce use of set -e with tooling. This change also adds -u and set -o pipefail in the less complex scripts where it is unlikely to cause problems. A follow-up change will enable those options in the complex scripts so that if it breaks something it can be reverted easily.

Add element to run DHCP on all network interfaces. Ensures that all network interfaces are present in /etc/network/interfaces. Any interface not already defined there will be added and configured for DHCP. Change-Id: I27e0902e62804e8d719acd7288109bd0e294fd16 2013-03-05 17:34:19 +00:00

Rename generate-interfaces-file.sh... Rename generate-interfaces-file.sh to dhcp-all-interfaces.sh so that it is easier to find/remember in the $PATH on a deployed image. Also, on some distros the script actually generates many files so the previous name was a bit confusing.

Implement dhcp-all-interfaces for systemd. Includes: * Enhancements to the generate-interfaces-file.sh script so that it generates ifcfg network-scripts for distros like Fedora/RHEL. * Includes a new dhcp-all-interfaces.service systemd script which ensures network interfaces get generated before the network service starts on Fedora. * Add a new disable_interface function to generate-interfaces-file.sh which (on Fedora) will delete the ifcfg config for an interface which isn't plugged in. This is important because ifcfg-eth0 exists by default and we want to remove it if the NIC isn't connected. Previous behaviour on Ubuntu is unchanged and the generate-interfaces-file.sh just logs it as skipped. * General doc updates... I tested this on a multi-nic machine w/ Fedora where the first NIC exists but was not connected. Change-Id: Ia99e312539da43caefd72aa60398d43dac5dcc8f Closes-Bug: 1239880 2014-01-09 20:32:52 +00:00

Conditionally add dhcp-all-interfaces If the /etc/init drectory gets created on Fedora, it causes os-svc-daemon to add upstart init scripts instead of systemd. As a result none of the openstack services can start.

DHCP: make udev rules want dhcp-interface@.service Updates the dhcp-all-interfaces element to fix a race with the recent udev rules implementation on Fedora. With the new approach we make the udev rule want (require to startup) a generic dhcp-interface@.service template which can be started individually for each interface that is discovered. The dhcp-interface@.service is setup such that it: 1) It calls dhcp-all-interfaces <iface> directly with a pre-exec script. This creates the ifcfg file right before we need it but avoids the case where network.service might get greedy and try to start it itself. 2) Only runs if the ifcfg script doesn't already exist. This is important because we only need to bootstrap the DHCP configs... Once they exist the network.service will take care of starting them on reboots, upgrades, etc. 3) On initial boot ensure that the initial DHCP interfaces come up after network.service. Since we really only want dhcp-all-interfaces to help bootstrap that haven't already been configured this seems reasonable. 4) We also try to ensure that cloud-init comes up after the DHCP interfaces. Cloud init has a decently long timeout that this wasn't a functional problem but it keeps log file spew down.
