In addition to EPOCHREALTIME there is also an EPOCHSECONDS environment
variable that OpenNebula needs to exclude as it is expected to change.
This commit supplements the other exclusion in commit
d1a2fe7307e9cf2251d1f9a666c12d71d3f522d6.
Without this fix, unittests will intermittently fail if
parse_shell_config is run across a timing boundary where the
EPOCHSECONDS changes mid-test.

The systemd generator used had a hard coded path for the location target
file to create. This path does not apply to all distributions.
Make the generator and template to have the path set during build time.

This branch is needed to allow cloud-init to sbuild on Ubuntu Disco.
OpenNebula:parse_shell_config tries to do a comparison of bash
environment values, excluding expected environment variables which
are known to change.
Bash on Ubuntu Disco surfaces a new EPOCHREALTIME environment variable
which wasn't in previous bash environments, this var needs to be
ignored by parse_shell_config too.

When using a proxy it is often useful to know in advance which mirrors
are to be contacted, so a whitelist can be set up. This is not easy when
using the yum.conf(5) mirrorlist option, as the retrieved list of mirrors
may change. The repository definition may also specify a canonical mirror
with the 'baseurl' option; this option is often commented out by default
to favor the usage of worldwide mirrors. This patch uncomments 'baseurl'
when an http_proxy is being used, so the canonical mirror is used *in
addition to* the mirrors retrieved from the mirrorlist.

When using the LXD module cloud-init will attempt
to install ZFS if it does not exist on the target
system. However instead of installing the `zfsutils-linux`
package it attempts to install `zfs` resulting in an error.
Ubuntu Xenial (16.04) has zfs meta package, but Bionic (18.04)
does not. Use the specific base package instead of zfs meta.

Writing the file with no dns information may prevent distro tools
from writing a resolv.conf file with dns information obtained from
a dhcp server.

The 'sysconfig' renderer is activated if, and only if, there's ifup and
ifdown commands present in its search dictonary or the network-scripts
configuration files are found. This patch adds a check for Network-
Manager configuration file as well.
This solution is based on the use of the plugin 'ifcfg-rh' present in
Network-Manager and is designed to support Fedora 29 or other
distributions that also replaced network-scripts by Network-Manager.

cloud-init uses dhclient to fetch the DHCP lease so it can extract
DHCP options. dhclient creates the leasefile, then writes to it;
simply waiting for the leasefile to appear creates a race between
dhclient and cloud-init. Instead, wait for dhclient to be parented by
init. At that point, we know it has written to the leasefile, so it's
safe to copy the file and kill the process.
cloud-init creates a temporary directory in which to execute dhclient,
and deletes that directory after it has killed the process. If
cloud-init abandons waiting for dhclient to daemonize, it will still
attempt to delete the temporary directory, but will not report an
exception should that attempt fail.

Testing startup of large numbers of VMs (of varying distros) in Azure
shows that 3 retries results in a small percentage of failed VMs.
Increasing that by a few dramatically decreases the occurrence of
provisioning timeout errors. The initial choice of "3 retries" was
uninformed by heavy testing. Also, the alternate provisioning
mechanism for Azure (waagent) retries the Wireserver crawl without
limit. 10 retries seems a more reasonable choice.
|
|
This adds documentation intended for a developer on how to add
a new datasource to cloud-init.

The change to datasources.rst here is obvious typo fix.
The change to azure is to reduce the two 'Customization' sections
to a single and clean up some other duplicate text.

ovf_vmware_transport_guestinfo is not currently tested.
It used '$1' instead of '$out' when checking for xml content in
the output of vmware-rpctool.
|
|
The change here will utilize ssh keys found inside an instance's tag.
The tag value must start with 'AUTHORIZED_KEY'.
|
|
Transport functions (transport_iso9660 and transport_vmware_guestinfo)
would return a tuple of 3 values, but only the first was ever used
outside of test. The other values (device and filename) were just
ignored.
This just simplifies the transport functions to now return content
(in string format) or None indicating that the transport was not found.
|
|
This adds support for reading OVF information over the
'com.vmware.guestInfo' tranport. The current implementation requires
vmware-rpctool be installed in the system.

In the Hacking doc, change the contact information for the contributors
agreement to reference Josh Powers rather than Scott Moser.

The tip-pylint tox target correctly reported the invalid use of
string formatting. The change here is to:
a.) Fix the error that was caught.
b.) move to pylint 2.2.2 for the default 'pylint' target.

It is possible to have a metric value in a per-subnet route.
This is currently missing in all renderers. Update each
renderer to emit the correct metric value from the config.

Add 'append: true' to write_files entries to append 'content' to file

Infrastructure is now set up for Ubuntu to handle Amazon instances
hitting a ports archive at:
- http://%(ec2_region)s.ec2.ports.ubuntu.com/ubuntu-ports/
And additionally, generic mirrors at
*.clouds.ports.ubuntu.com/ubuntu-ports
The change here will utilize those mirrors for the arm64, armel and
armhf arches.
We've decided to limit the auto-selection of those
mirrors to arm, where we know a use case. That way new instances
of ppc64el or other arches will not select them. Such a behavior change
could be problematic for a user in a firewalled environment.

I noticed a bug in dhclient_hook on the 'down' event, using 'is'
operator rather than '==' (if self.net_action is 'down').
This refactors/simplifies the code a bit for easier testing and adds
tests. The reason for the rename of 'action' to 'event' is to just
be internally consistent. The word and Namespace 'action' is used
by cloud-init main, so it was not really usable here.
Also adds a main which can easily be debugged with:
CI_DHCP_HOOK_DATA_D=./my.d python -m cloudinit.dhclient_hook up eth0

NoCloud's 'network-config' file was originally expected to contain
network configuration without the top level 'network' key. This was
because the file was named 'network-config' so specifying 'network'
seemed redundant.
However, JuJu is currently providing a top level 'network' config when
it tries to disable networking ({"network": {"config": "disabled"}).
Other users have also been surprised/confused by the fact that
a network config in /etc/cloud/cloud.cfg.d/network.cfg differed from
what was expected in 'network-config'.

Move routes under the nic's subnet rather than use top-level
("global") route config ensuring all net renderers will provide the
configured route.
Also updated cloudinit/cmd/devel/net_convert.py:
- Add input type 'vmware-imc' for OVF customization config files
- Fix bug when output-type was netplan which invoked netplan
generate/apply and attempted to write to
/etc/netplan/50-cloud-init.yaml instead of joining with the
output directory.

Replace Azure pre-provision polling on IMDS with a blocking call
which watches for netlink link state change messages. The media
change event happens when a pre-provisioned VM has been activated
and is connected to the users virtual network and cloud-init can
then resume operation to complete image instantiation.

Check the appropriate variables based on code review. Correcting what
seems to be a copy/paste mistake for the error handling from a few lines
above.

The order of parameters to test_handle_zfs_root did not match
the order of the mocks applied.
Thanks to Jason Zions for pointing this out.

According to the examples in the page, v1 network config DNS should
be defined using the dns_nameservers. The singular dns_nameserver is
undefined.

When deploying an OVA, at least some versions of vmware
attach a cdrom with an ISO9660 filesystem label of 'OVF ENV'.
This was seen on Vmware vCenter Server, 6.0.0, 2776510.
In order to accomplish this we had to change the content of
the DI_ISO9660_DEVS variable to be comma delimited rather
than space delimited.

Since /run/cloud-init/instance-data-sensitive.json is root read-only,
ignore this file if non-root user runs collect-logs.
If --include-userdata is provided on the command line, exit in error
if non-root user attempts this operation.
Lastly, update the __main__ to exit based on return value of main.

We add a new Optional parameter: connectivity_url
This is used in __enter__ to verify if a connection already exists.
If it does exist, no operations are performed.

Upon URL timeout, _poll_imds is expected to re-dhcp to get updated
IP configuration. We don't want to indefinitely retry because the
instance likely has invalid IP configuration.

In some environments, like FreeBSD, gpart can return the device basename
instead of the full path. If this discovered devpath does not exist and
is missing the '/dev/' prefix, add that prefix in an attempt to find the
device.

There is an infrequent race when the booting instance can hit the IMDS
service before it is fully available. This results in a
requests.ConnectTimeout being raised.
Azure's retry_callback logic now retries on either 404s or Timeouts.

If Azure detects an ntfs filesystem type during mount attempt, it should
still report the resource device as reformattable. There are slight
differences in error message format on RedHat and SuSE. This patch
simplifies the expected error match to work on both distributions.

In commitish 9073951 azure datasource tried to leverage stale DHCP
information obtained from EphemeralDHCPv4 context manager to report
updated provisioning status to the fabric earlier in the boot process.
Unfortunately the stale ephemeral network configuration had already been
torn down in preparation to bring up IMDS network config so the report
attempt failed on timeout.
This branch introduces obtain_lease and clean_network public methods on
EphemeralDHCPv4 to allow for setup and teardown of ephemeral network
configuration without using a context manager. Azure datasource now uses
this to persist ephemeral network configuration across multiple contexts
during provisioning to avoid multiple DHCP roundtrips.

Cloud-init delivers udev rules on Azure to create the following symlinks:
- /dev/disk/cloud/azure_root
- /dev/disk/cloud/azure_root-part#
- /dev/disk/cloud/azure_resource
- /dev/disk/cloud/azure_resource-part#
Cloud-init cc_disk_setup expects presence of these dev links in order to
setup the mounted ephemeral disks. Gen1 instances udev rules match based
only a DEVICE_ID attribute that no longer exists on Gen2 instances.
Supplement existing Gen1 rules with matches on specitic SCSI target/lun
path 0:0:0 and 0:0:1 and generate links for azure_root and azure_resource
respectively.

When reusing a preprovisioned VM, report ready to Azure fabric as soon as
we get the reprovision data and the goal state so that we are not delayed
by the cloud-init stage switch, saving 2-3 seconds. Also reduce logging
when polling IMDS for reprovision data.

Emit a permissions error instead of "Missing instance-data.json" when
non-root user doesn't have read-permission on
/run/cloud-init/instance-data.json
|
|
On cloud-init upgrade path from 18.3 to 18.4 cloud-init changed how
instance-data is written. Cloud-init changes instance-data.json from root
read-only to redacted world-readable content, and provided a separate
unredacted instance-data-sensitive.json which is read-only root.
Since instance-data is only rewritten from cache on
reboot, the query and render tools needed fallback to use the 'old'
instance-data.json if the new sensitive file isn't yet present.
This avoids error messages from tools about an absebt
/run/instance-data-sensitive.json file.
