Add a `PerAlloc` field to volume requests that directs the scheduler to test
feasibility for volumes with a source ID that includes the allocation index
suffix (ex. `[0]`), rather than the exact source ID.
Read the `PerAlloc` field when making the volume claim at the client to
determine if the allocation index suffix (ex. `[0]`) should be added to the
volume source ID.
* Fixup uses of `sanity`
* Remove unnecessary comments.
These checks are better explained by earlier comments about
the context of the test. Per @tgross, moved the tests together
to better reinforce the overall shared context.
* Update nomad/fsm_test.go
* fix periodic
* update periodic to not use template
nomad job inspect no longer returns an apiliststub so the required fields to query job summary are no longer there, parse cli output instead
* rm tmp makefile entry
* fix typo
* revert makefile change
This PR enables jobs configured with a custom sidecar_task to make
use of the `service.expose` feature for creating checks on services
in the service mesh. Before we would check that sidecar_task had not
been set (indicating that something other than envoy may be in use,
which would not support envoy's expose feature). However Consul has
not added support for anything other than envoy and probably never
will, so having the restriction in place seems like an unnecessary
hindrance. If Consul ever does support something other than Envoy,
they will likely find a way to provide the expose feature anyway.
Fixes#9854
This PR adds pid_mode and ipc_mode options to the exec and java task
driver config options. By default these will defer to the default_pid_mode
and default_ipc_mode agent plugin options created in #9969. Setting
these values to "host" mode disables isolation for the task. Doing so
is not recommended, but may be necessary to support legacy job configurations.
Closes#9970
Ensure that the e2e clusters are isolated and never attempt to autojoin
with another e2e cluster.
This ensures that each cluster servers have a unique `ConsulAutoJoin`,
to be used for discovery.
The connect tests are very disruptive: restart consul/nomad agents with new
tokens. The test seems particularly flaky, failing 32 times out of 73 in my
sample.
The tests are particularly problematic because they are disruptive and affect
other tests. On failure, the nomad or consul agent on the client can get into a
wedged state, so health/deployment info in subsequent tests may be wrong. In
some cases, the node will be deemed as fail, and then the subsequent tests may
fail when the node is deemed lost and the test allocations get migrated unexpectedly.
The nodedrain deadline test asserts that all allocations are migrated by the
deadline. However, when the deadline is short (e.g. 10s), the test may fail
because of scheduler/client-propagation delays.
In one failing test, it took ~15s from the RPC call to the moment to the moment
the scheduler issued migration update, and then 3 seconds for the alloc to be
stopped.
Here, I increase the timeouts to avoid such false positives.
Increase the timeout for vaultsecrets. As the default interval is 0.1s, 10
retries mean it only retries for one second, a very short time for some waiting
scenarios in the test (e.g. starting allocs, etc).
Prefer testutil.WaitForResultRetries that emits more descriptive errors on
failures. `require.Evatually` fails with opaque "Condition never satisfied"
error message.
This is an attempt at deflaking the e2e exec tests, and a way to improve
messages.
e2e occasionally fail with "unexpected EOF" even though the exec output matches
expectations. I suspect there is a race in handling EOF in server/http handling.
Here, we special case this error and ensures we get all failures,
to help debug the case better.
This PR makes two ergonomics changes, meant to get e2e builds more reproducible and ease changes.
### AMI Management
First, we pin the server AMIs to the commits associated with the build. No more using the latest AMI a developer build in a test branch, or accidentally using a stale AMI because we forgot to build one! Packer is to tag the AMI images with the commit sha used to generate the image, and then Terraform would look up only the AMIs associated with that sha. To minimize churn, we use the SHA associated with the latest Packer configurations, rather than SHA of all.
This has few benefits: reproducibility and avoiding accidental AMI changes and contamination of changes across branches. Also, the change is a stepping stone to an e2e pipeline that builds new AMIs automatically if Packer files changed.
The downside is that new AMIs will be generated even for irrelevant changes (e.g. spelling, commits), but I suspect that's OK. Also, an engineer will be forced to build the AMI whenever they change Packer files while iterating on e2e scripts; this hasn't been an issue for me yet, and I'll be open for iterating on that later if it proves to be an issue.
### Config Files and Packer
Second, this PR moves e2e config hcl management to Terraform instead of Packer. Currently, the config files live in `./terraform/config`, but they are baked into the servers by Packer and changes are ignored. This current behavior surprised me, as I spent a bit of time debugging why my config changes weren't applied. Having Terraform manage them would ease engineer's iteration. Also, make Packer management more consistent (Packer only works `e2e/terraform/packer`), and easing the logic for AMI change detection.
The config directory is very small (100KB), and having it as an upload step adds negligible time to `terraform apply`.
This PR implements Nomad built-in support for running Consul Connect
terminating gateways. Such a gateway can be used by services running
inside the service mesh to access "legacy" services running outside
the service mesh while still making use of Consul's service identity
based networking and ACL policies.
https://www.consul.io/docs/connect/gateways/terminating-gateway
These gateways are declared as part of a task group level service
definition within the connect stanza.
service {
connect {
gateway {
proxy {
// envoy proxy configuration
}
terminating {
// terminating-gateway configuration entry
}
}
}
}
Currently Envoy is the only supported gateway implementation in
Consul. The gateay task can be customized by configuring the
connect.sidecar_task block.
When the gateway.terminating field is set, Nomad will write/update
the Configuration Entry into Consul on job submission. Because CEs
are global in scope and there may be more than one Nomad cluster
communicating with Consul, there is an assumption that any terminating
gateway defined in Nomad for a particular service will be the same
among Nomad clusters.
Gateways require Consul 1.8.0+, checked by a node constraint.
Closes#9445
* Prevent Job Statuses from being calculated twice
https://github.com/hashicorp/nomad/pull/8435 introduced atomic eval
insertion iwth job (de-)registration. This change removes a now obsolete
guard which checked if the index was equal to the job.CreateIndex, which
would empty the status. Now that the job regisration eval insetion is
atomic with the registration this check is no longer necessary to set
the job statuses correctly.
* test to ensure only single job event for job register
* periodic e2e
* separate job update summary step
* fix updatejobstability to use copy instead of modified reference of job
* update envoygatewaybindaddresses copy to prevent job diff on null vs empty
* set ConsulGatewayBindAddress to empty map instead of nil
fix nil assertions for empty map
rm unnecessary guard
After submitting an update, the test ought to wait until the new
allocations are placed. Previously, we'd use the original to-be-stopped
allocations and the test fails when attempting to exec.
Deflake namespace e2e test by only asserting on jobs related to the
namespace tests. During our e2e tests, some left over jobs (e.g.
prometheus) are left running while being shutdown and cause the test to
fail.
Connect ingress gateway services were being registered into Consul without
an explicit deterministic service ID. Consul would generate one automatically,
but then Nomad would have no way to register a second gateway on the same agent
as it would not supply 'proxy-id' during envoy bootstrap.
Set the ServiceID for gateways, and supply 'proxy-id' when doing envoy bootstrap.
Fixes#9834
