Ports the rescheduling tests (which aren't running in CI) into the current
test framework so that they're run on nightly, and exercises the new CLI
helpers.
The E2E suite exercises the API, but not the CLI. This changeset adds a helper
function to send commands via a locally-built Nomad binary (which we'll need
to add to the E2E setup), and some helpers to parse the resulting structured
outputs in a way that tests can consume.
Copy Consul API's format: QueryOptions.WithContext(context) will now return
a new QueryOption whose HTTP requests will be canceled with the context
provided (and similar for WriteOptions)
When running the Fabio and Prometheus jobs for the metrics suite
it seems the outer directory is required in the call when
registering the job.
error: "e2e/input/fabio.nomad: no such file or directory"
The job factory will now accept an array of resourceSpecs that is a shorthand
notation for memory, cpu, disk, and iops requirements.
These specs get passed down to task groups. The task group factory will
split the resource requirements near evenly (there is variance
threshold) across all expected tasks.
Allocations then construct task-resource objects based on the resources
from the matching task.
This changeset stages upcoming E2E provisioning improvements work. It splits
the existing shared configuration directory into 3 profiles:
* "full-cluster": the set of configurations currently in use
* "dev-cluster": a simplified set of mostly existing configurations that
weren't in use.
* "custom": an empty profile for developers to keep non-standard
configurations during complex feature development.
The tooling to switch between profiles will be in a later changeset.
Also drops some unused configuration knobs from the provisioning scripts to
make the next stage of work easier.
Our provisioning process for E2E doesn't require the `depends_on` fields to be
set for client instances, so dropping that field allows all instances to be
started in parallel.
We don't use the extra EBS volumes (they aren't even mounted), so remove them
to reduce costs.
The `-recursor` flag in the Consul service unit files is specific to a given
cloud, but we already have cloud-specific configuration files. Consolidate all
the cloud-specific items into the config.
