Michael Schurter 8d1419c62b client: fix accessing alloc runners 
* GetClientAlloc() gains nothing from using allAllocs()
* getAllocatedResources was calling getAllocRunners() twice
 2018-10-16 16:56:55 -07:00
Michael Schurter e6e2930a00 tr: implement stats collection hook 
Tested except for the net/rpc specific error case which may need
changing in the gRPC world.

Alex Dadgar 8504505c0d client uses passed logger and fix fingerprinters 2018-10-16 16:53:30 -07:00
Michael Schurter 9d1ea3b228 client: hclog-ify most of the client 
Leaving fingerprinters in case that interface changes with plugins.
 2018-10-16 16:53:30 -07:00
Michael Schurter e42154fc46 implement stopping, destroying, and disk migration 
* Stopping an alloc is implemented via Updates but update hooks are
  *not* run.
* Destroying an alloc is a best effort cleanup.
* AllocRunner destroy hooks implemented.
* Disk migration and blocking on a previous allocation exiting moved to
  its own package to avoid cycles. Now only depends on alloc broadcaster
  instead of also using a waitch.
* AllocBroadcaster now only drops stale allocations and always keeps the
  latest version.
* Made AllocDir safe for concurrent use

Lots of internal contexts that are currently unused. Unsure if they
should be used or removed.

Michael Schurter 4236255686 lots of comment/log fixes 2018-10-16 16:53:30 -07:00
Michael Schurter 357641c364 persist alloc state on changes, not periodically 
Allow alloc and task runners to persist their own state when something
changes instead of periodically syncing all state.

Updates are applied asynchronously but sequentially
 2018-10-16 16:53:30 -07:00
Michael Schurter a4b4d7b266 consul service hook 
Deregistration works but difficult to test due to terminal updates not
being fully implemented in the new client/ar/tr.

Michael Schurter 516d641db0 client: implement all-or-nothing alloc restoration 
Restoring calls NewAR -> Restore -> Run

NewAR now calls NewTR
AR.Restore calls TR.Restore
AR.Run calls TR.Run

Michael Schurter 0f7dcfdc9a example redis job "runs" on arv2! see below 
Tons left to do and lots of churn:
1. No state saving
2. No shutdown or gc
3. Removed AR factory *for now*
4. Made all "Config" structs local to the package they configure
5. Added allocID to GC to avoid a lookup

Really hating how many things use *structs.Allocation. It's not bad
without state saving, but if AllocRunner starts updating its copy things
get racy fast.

Alex Dadgar f24ce2c50c Driver health detection cleanups 
This PR does:

1. Health message based on detection has format "Driver XXX detected"
and "Driver XXX not detected"
2. Set initial health description based on detection status and don't
wait for the first health check.
3. Combine updating attributes on the node, fingerprint and health
checking update for drivers into a single call back.
4. Condensed driver info in `node status` only shows detected drivers
and make the output less wide by removing spaces.

Alex Dadgar 49a47483d1 Registering back to initializing 
Fix a bug in which if the node attributes/meta changed, we would

It would change the status of the Node to initializing until the next
heartbeat occured.

Chelsea Komlo 2dfda33703 Nomad agent reload TLS configuration on SIGHUP (#3479) 
* Allow server TLS configuration to be reloaded via SIGHUP

* dynamic tls reloading for nomad agents

* code cleanup and refactoring

* ensure keyloader is initialized, add comments

* allow downgrading from TLS

* initalize keyloader if necessary

* integration test for tls reload

* fix up test to assert success on reloaded TLS configuration

* failure in loading a new TLS config should remain at current

Reload only the config if agent is already using TLS

* reload agent configuration before specific server/client

lock keyloader before loading/caching a new certificate

* introduce a get-or-set method for keyloader

* fixups from code review

* fix up linting errors

* fixups from code review

* add lock for config updates; improve copy of tls config

* GetCertificate only reloads certificates dynamically for the server

* config updates/copies should be on agent

* improve http integration test

* simplify agent reloading storing a local copy of config

* reuse the same keyloader when reloading

* Test that server and client get reloaded but keep keyloader

* Keyloader exposes GetClientCertificate as well for outgoing connections

* Fix spelling

* correct changelog style

Michael Schurter 2a81160dcd Fix GC'd alloc tracking 
The Client.allocs map now contains all AllocRunners again, not just
un-GC'd AllocRunners. Client.allocs is only pruned when the server GCs

Alex Dadgar 07ed83fdd5 Non-locked accessors to common Node fields 
This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.
