Pretty sure Consul / Nomad clients are often not ready yet after
the ConsulACLs test disables ACLs, by the time the next test starts
running.
Running locally things tend to work, but in TeamCity this seems to
be a recurring problem. However, when running locally sometimes I do
see that the "show status" step after disabling ACLs, some nodes are
still initializing, suggesting we're right on the border of not waiting
long enough
nomad node status
ID DC Name Class Drain Eligibility Status
0e4dfce2 dc1 EC2AMAZ-JB3NF9P <none> false eligible ready
6b90aa06 dc2 ip-172-31-16-225 <none> false eligible ready
7068558a dc2 ip-172-31-20-143 <none> false eligible ready
e0ae3c5c dc1 ip-172-31-25-165 <none> false eligible ready
15b59ed6 dc1 ip-172-31-23-199 <none> false eligible initializing
Going to try waiting a full 2 minutes after disabling ACLs, hopefully that
will help things Just Work. In the future, we should probably be parsing the
output of the status checks and actually confirming all nodes are ready.
Even better, maybe that's something shipyard will have built-in.
Go implicitly treats files ending with `_linux.go` as build tagged for
Linux only. This broke the e2e provisioning framework on macOS once we
tried importing it into the `e2e/consulacls` module.
This changeset improves the ergonomics of running the Nomad e2e test
provisioning process by defaulting to a blank `nomad_sha` in the
Terraform configuration. By default, a user will now need to pass in
one of the Nomad version flags. But they won't have to manually edit
the `provisioning.json` file for the common case of deploying a
released version of Nomad, and won't need to put dummy values for
`nomad_sha`.
Includes general documentation improvements.
Fixes a panic when accessing a.agent.Server() when agent is a client
instead. This pr removes a redundant ACL check since ACLs are validated
at the RPC layer. It also nil checks the agent server and uses Client()
when appropriate.
Consolidate all nomad data dir in a single root
`/tmp/nomad-dev-cluster`. Eases clean up.
Allow running script from any path - don't require devs to cd into
`dev/cluster` directory first.
Also, block while nomad processes are running and prapogate
SIGTERM/SIGINT to nomad processes to shutdown.
diffSystemAllocs -> diffSystemAllocsForNode, this function is only used
for diffing system allocations, but lacked awareness of eligible
nodes and the node ID that the allocation was going to be placed.
This change now ignores a change if its existing allocation is on an
ineligible node. For a new allocation, it also checks tainted and
ineligible nodes in the same function instead of nil-ing out the diff
after computation in diffSystemAllocs
