DataSource.get_hostname call signature changed to allow for metadata_only
parameter. The metadata_only=True parameter is passed to get_hostname
during init-local stage in order to set the system hostname if present in
metadata prior to initial network bring up.
Fix subclasses of DataSource which have overridden get_hostname to allow
for metadata_only param.
OpenNebula: Update network to return v2 config rather than ENI.
OpenNebulaNetwork.gen_conf() was previously returning ENI format.
This is updated to return netplan/v2 config.
The changes here also adds support for IPv6 configuration distributed
from OpenNebula and fixes some issues about nameserver information.
net: recognize iscsi root cases without ip= on kernel command line.
When 'ip=' or 'ip6=' is found on the kernel command line,
cloud-init will consider read network config from /run/net-*.conf files.
There are some iscsi-root scenarios where initramfs configures networking
but the ip= parameter is not present. 2 such cases are:
a.) static config in /etc/iscsi/iscsi.initramfs (copied into the
initramfs)
b.) iBft
This changes cloud-init to consider initramfs provided networking
information if:
* there are /run/net-* files and
* (ip= or ip6 is on the command line) or open-iscsi.interface file
exists.
cc_snap: Add new module to install and configure snapd and snap packages.
Support installing and configuring snaps on ubuntu systems. Now,
cloud-config files can provide a list or dictionary of snap:assertions
which will be allow configuration of snapd on a system via 'snap ack'
calls. The snap:commands configuration option supports arbitrary system
commands intended to interact with snappy's cli. This allows users to run
arbitrary snappy commands to create users, download, install and
configure snap packages and snapd.
This branch also deprecates old snappy and snap_config modules leaving
warnings in documentation and runtime for consumers of these modules.
Deprecated snap* modules will be dropped in cloud-init v.18.2 release.
tests: Make pylint happy and fix python2.6 uses of assertRaisesRegex.
Older unittest2.TestCase (as seen in CentOS 6) do not have an
assertRaisesRegex method. They only have the now-deprecated
assertRaisesRegexp.
We need our unit tests to work there and on newer python (3.6).
Simply making assertRaisesRegex = assertRaisesRegexp makes pylint
complain as described in https://github.com/PyCQA/pylint/issues/1946 .
What was here before this commit was actually broken. This commit
makes assertRaisesRegex functional in CentOS 6 and works around
the invalid Deprecated warning from pylint.
To prove this, we use assertRaisesRegex in a unit test which will
be exectued in py27, py3 and py26.
util: Fix subp regression. Allow specifying subp command as a string.
The command provided to subp can either be a string or a list. This patch
fixes a regression which raised CalledProcessError whenever providing a
string to subp.
