In starting containers in lxc, I was seeing errors like:
/proc/self/fd/9: 24: kill: No such process
Which indicated the sleep pid had already died.
I'm not sure how or why it was dead, but this just is less annoying in that
case.

ifquery will exit failure if there is no /run/network directory.
normally that would get created by one of network-interface.conf
or networking.conf. But, it is possible that we're running
before either of those have.

This changes the way that we avoid cloud-init-nonet hanging in a container.
Previously, under LP: #800824 we tried 'start networking', but that caused
issues described in LP: #1031065.
Here, we emit the net-device-added for any devices that have not yet been
seen.

This just updates upstart jobs to the new single binary approach.

This should not happen any time in the near future, but /var/run
is actually legacy, so accept that it might not be there.
|

This continues the change in this file that intended to wait
for all networking to be up. The logic that was there would
cause it to start cloud-init immediately if a single non-lo
interface was up.
This will basically just check if 'static-network-up' has occurred
during this boot.
There could be an issue if /var/run was populated from a previous
boot, but since its really expected to be a tmpfs, can't have anything
in it.

This moves what was done as cloud-run-user-script.conf to 'cloud-final'
and makes that re-use the cloud-init-cfg code, but simply with a different
set of default configs.
Also, adds keys_to_console and final_message cloud-config modules
LP: #653271
|
|
instead of hard-coding in cloud-init-cfg the module list that should be
read, read it from the second command line argument. Basically, instead
of reading 'cloud_config_modules', specify 'cloud_config' when
cloud-init-cfg is run.
change the upstart job to invoke cloud-init-cfg with:
exec cloud-init-cfg all cloud_config
rather than
exec cloud-init-cfg all
|
|
Now, in addition to running instance specific scripts (in runcmd or
user-data scripts), cloud-run-user-script will run other directories
also. All under /var/lib/cloud, and in the following order:
scripts/per-once [once ever]
scripts/per-boot [every boot]
scripts/per-instance [once per instance]
instance/scripts [once per instance]
At the moment, the marker is on the entire directory, so changes to that
directory. Changes to the contents of the directory will not be noticed.

Previously, if you ran an instance with either runcmd data or user-data
scripts, it would run again after rebundle or create-image.
This puts the files created by runcmd or user-data scripts into instance-id
specific paths, and then runs them by that instance-id specific path.

The new classes 'DataSourceNoCloud' and 'DataSourceNoCloudNet'
implement a way to get data from the filesystem, or (very minimal)
data from the kernel command line. This allows the user to seed data to
these sources.
There are now 2 "cloud-init" jobs, cloud-init-local that runs on
mounted MOUNTPOINT=/
and 'cloud-init' that runs on
start on (mounted MOUNTPOINT=/ and net-device-up IFACE=eth0 and
stopped cloud-init-local )
The idea is that cloud-init-local can actually function without network.
The last thing in this commit is "uncloud-init".
This tool can be invoked as 'init=/usr/lib/cloud-init/uncloud-init'
It will "uncloudify" things in the image, generally making it easier
to use for a simpler environment, and then it will exec /sbin/init.

The list of cloud-config modules is now kept in cloud config itself.
There is a builtin list in cloudinit, which is overrideable by
/etc/cloud/cloud.cfg or user data cloud-config.
This should make the modules more easily added or removed (as no code
needs to be edited now)
Basic summary of changes:
- move CloudConfig.py -> cloudinit/CloudConfig/__init__.py
- split cloud-config modules into their own files named
cloudinit/CloudConfig/cc_<name>.py
- remove all the upstart/cloud-config-* scripts, replacing them with
upstart/cloud-config.conf

cloud-config. Doing so means the collision that was occuring with
upstart/mountall will not occur. However, it also means any mounts
configured will not be mounted until later. LP: #527825

Some changes were rushed in prior to lucid beta that didn't get pulled
back into the upstream release. I'm pulling those in here.

cloud-config-misc is adding a script to the directory
where user-scripts go, so run-user-script has to wait on it.
|
|
|
|
LP: #523625
|
|
cloud-run-user-script was never running because it depended on
'stopped cloudinit', rather than
'stopped cloud-init'.

This fixes LP: #506599 , LP: #507070 .
Also, here, we move config parsing out of the EC2Init class.
Instead the parsing of /etc/ec2-init/ec2-init.cfg is now done in the
CloudConfig class, and prepended to the cloud-config that comes in
from user data. This means that values in user data will over-ride
the settings in /etc/ec2-init.
Still TODO is support reading the public and private key files from
the cloud-config

|
At this point, the following should be functional:
cloud-init-cfg apt-update-upgrade
|
|
1. arguments to run-parts came before run-parts
2. explicitly state that we dont want this script to run
until cloud-config is done
|
|
|
|
run-parts didn't like scripts ending in .sh apparently.
the man page says:
If neither the --lsbsysinit option nor the --regex option is given
then the names must consist entirely of upper and lower case letters,
digits, under‐ scores, and hyphens.
We dont want to have such a restriction. so run with
--regex '.*'
Second change is making this run once-per-instance .
