This removes a cyclical dependency when importing client/structs from
dependencies of the plugin_loader, specifically, drivers. Due to
client/config also depending on the plugin_loader.
It also better reflects the ownership of fingerprint structs, as they
are fairly internal to the fingerprint manager.
This change removes the addition of the advertise address to the
exported task env vars and instead moves this work into the
NomadFingerprint.Fingerprint which adds this value to the client
attrs. This can then be used within a Nomad job like
${attr.nomad.advertise.address}.
Allow to set the total memory of an agent in its configuration file. This
can be used in case the automatic detection doesn't work or in specific
environments when memory overcommit (using swap for example) can be
desirable.
Certain environments use WARN for serious logging; however, it's very
possible to have machines without some of the fingerprinted keys
(public-ipv4 and public-hostname specifcally). Setting log level to
INFO seems more consistent with this possibility.
This PR introduces a better interface selection heuristic such that we
select interfaces with globally routable unicast addresses over link
local addresses.
Fixes https://github.com/hashicorp/nomad/issues/3487
This PR changes the fingerprint handling of network interfaces that only
contain link local addresses. The new behavior is to prefer globally
routable addresses and if none are detected, to fall back to link local
addresses if the operator hasn't disallowed it. This gives us pre 0.6
behavior for interfaces with only link local addresses but 0.6+ behavior
for IPv6 interfaces that will always have a link-local address.

This PR:
* Uses Go 1.8 executable lookup
* Stores any err message from stats init method
* Allows overriding of Cpu Compute for hosts where it can't be detected
Previously, this value was guarded against running on Windows
because it called the `uname` command which is unlikely to
be there.
This change now sets the value from gopsutil, which might
well be an empty string.

Previously with client fingerprinting, sys/exec's Command
function was being used to execute `uname -r` and the return
string processed into the kernel.version node attribute.
This change uses gopsutil/host KernelVersion function
instead. This means we can drop the os/exec, strings and
fmt imports... and not execute an external binary.

This PR:
* Makes AWS network speeds more granular
* Makes `network_speed` an override and not a default
* Adds a default of 1000 MBits if no network link speed is detected.
Fixes#1985
If someone wants to extend or reuse Cgroup detenction in the future they
can move `cgroup_linux.go` to `cgroup.go` and add the relevant build
tags.
Requested by: @dadgar
Conditionalize the network fingerprinter test so that it works when a
user is offline. Similarly, when the network fingerprint test fails in
the future pass a HINT to the user to set an env var to allow the test
to be skipped in the future.
Change the logic from `!linux` to an empty build tag so that *if*
another platform picks up Cgroups support they can add themselves to the
necessary build tags for this fingerprinter and be on their way.
Because this technology isn't inherently Linux-specific and isn't
mutually exclusive of other resource isolation containers, resist the
urge to rename the Cgroup fingerprinter to something generic like the
ResourceContainerFingerprinter.
Change the unit test to only test if the consul link exists, not the
value of the link. The old test was hostname specific and therefore
would always be different based on the environment running the tests.
Reduce future confusion by introducing a minor version that is gossiped out
via the `mvn` Serf tag (Minor Version Number, `vsn` is already being used for
to communicate `Major Version Number`).

Fix URL. It was printing an error message on startup:
```
2015/11/13 15:49:21 [ERR] fingerprint.env_aws: Error querying AWS Metadata URL, skipping
```
By the way is it safe to use latest? Is there a chance that Amazon decides to change the format of the metadata? It could be safer to use something like `http://169.254.169.254/2014-11-05/meta-data`
