Consul Service Advertisement Refactor #2478
Comments
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.
