This attempts to retrieve cloudconfigs from two sources: the meta-data
service, and the user-data service. If only one cloudconfig is found,
that is applied to the system. If both services return a cloudconfig,
the two are merged into a single cloudconfig which is then applied to
the system.
Only a subset of parameters are merged (because the meta-data service
currently only partially populates a cloudconfig). In the event of any
conflicts, parameters in the user-data cloudconfig take precedence over
those in the meta-data cloudconfig.
This uses the new MetadataService implementation to retrieve values for
$private_ipv4 and $public_ipv4 substitutions, instead of using
environment variables.
Move the old metadata-service datasource to url datasource. This new datasource
checks for the existance of meta-data.json and if it doesn't exist, walks the
meta-data directory to build a metadata blob.
Supports retries with exponential backoff as well as connection
timeouts and the ability to skip SSL/TLS verification.
This commit also refactors datasource and initialize packages
in order to use the new HTTP client.
This change creates a few simple interfaces for coreos-specific
configuration options and moves things to them wherever possible; so if
an option needs to write a file, or create a unit, it is acted on
exactly the same way as every other file/unit that needs to be written
during the cloud configuration process.
daemon-reload should be fixed now and the latest CoreOS with locksmith
is causing the etcd unit to get lazy-loaded before all the cloudinit
processes have finished configuring etcd via dropin files. In short,
the luck we were relying on to get by without daemon-reload has
officially run out. Cross your fingers!
This reverts commit 580460ff3f.
Fix#69 - A user may provide an `enable` attribute of a unit in their
cloud config document. If true, coreos-cloudinit will instruct systemd
to enable the associated unit. If false, the unit will not be enabled.
Fix#71 - The default enable behavior has been changed from on to off.
The update_engine parsing and XML generation code is very naive. Instead
of trying to implement a correct parser and generater in C++ just
generate a file that doesn't have quote's around fields that we know
won't have spaces.
