Michael Schurter 22690c5f4c Add check watcher for restarting unhealthy tasks 2017-09-14 16:46:54 -07:00
Alex Dadgar d86b3977b9 Fix alloc health with checks using interpolation
Fixes an issue in which the allocation health watcher was checking for
allocations health based on un-interpolated services and checks. Change
the interface for retrieving check information from Consul to retrieving
all registered services and checks by allocation. In the future this
will allow us to output nicer messages.

Alex Dadgar 067ed86a47 Client watches for allocation health using task state and Consul checks
This PR adds watching of allocation health at the client. The client can
watch for health based on the tasks running on time and also based on
the consul checks passing.

Michael Schurter b9bfb84b53 Implement DriverNetwork and Service.AddressMode
Ideally DriverNetwork would be fully populated in Driver.Prestart, but
Docker doesn't assign the container's IP until you start the container.

However, it's important to setup the port env vars before calling
Driver.Start, so Prestart should populate that.

Michael Schurter e204a287ed Refactor Consul Syncer into new ServiceClient
Fixes #2478 #2474 #1995 #2294

The new client only handles agent and task service advertisement. Server
discovery is mostly unchanged.

The Nomad client agent now handles all Consul operations instead of the
executor handling task related operations. When upgrading from an
earlier version of Nomad existing executors will be told to deregister
from Consul so that the Nomad agent can re-register the task's services
and checks.

Drivers - other than qemu - now support an Exec method for executing
abritrary commands in a task's environment. This is used to implement
script checks.

Interfaces are used extensively to avoid interacting with Consul in
tests that don't assert any Consul related behavior.
