Make the AWS e2e story work end to end

[frobware]

e2e-aws-operator runs the AWS end-to-end suite against an operator installed from its own bundle. Getting there takes two halves: the job is a sequence of steps you can each run by hand against a cluster of your own, and the operator finds AWS credentials for itself so it can run in the cluster rather than out of it. The second half subsumes #91, which is closed.

The job is defined by openshift/release#84073, now merged, without which none of this executes in CI. It gives e2e-aws-operator three steps: enable FRR, install the operator from the bundle this repository builds, and then run hack/ci-e2e-aws.sh. It also sets ZONES_COUNT: "2", because ipi-conf-aws resolves auto to a single zone for presubmits and against one zone the suite cannot tell correct per-AZ grouping from no grouping at all.

That third step is the only one that names anything in this repository, so what the test does can change here rather than through a round trip via openshift/release. It enables FRR, stands up the route server estate the operator expects to discover, labels the router nodes, writes a profile describing the estate it just built, runs make test-e2e-aws against it, and tears everything down whatever happened. hack/ci-e2e-aws-run.sh creates and never removes, hack/ci-e2e-aws-teardown.sh removes and never creates, and hack/ci-e2e-aws.sh is the only file that knows both exist.

Sequencing the teardown here rather than expressing it as a ci-operator post step is deliberate but not obviously permanent. A test that specifies post overrides the workflow's rather than adding to it, so a teardown step declared that way would replace ipi-aws-post and take the cluster deprovision with it. The ordering has to be ours regardless: route server endpoints sit in the subnets the installer wants to delete, so they have to go first.

The long-term shape is probably a workflow in the openshift/release step registry whose post is our teardown followed by ipi-aws-post, which is how aws-load-balancer-operator handles its own setup. That would buy something a trap cannot: prow runs post steps even when the test pod is killed outright, whereas the trap here converts an ordinary cancellation into a clean teardown and gives up once the grace period expires and the next signal is KILL. It would also report a teardown failure as infrastructure rather than as the test failing. The cost is that changing it then needs a release-repo pull request, which is the slower loop, and this job already takes about ninety minutes end to end, most of it queueing and installing a cluster. Keeping the teardown here while the suite is still moving is the cheaper trade; moving it once it settles is the safer one.

The suite reads a generated profile rather than a checked-in one. The profiles under test/e2e/manifests pin a route server id, which cannot work when the id is minted while the job is running, and it fails quietly because the suite filters endpoints on spec.aws.routeServerIDs and a stale id yields none rather than an error. E2E_MANIFEST_DIR lets the suite read a profile from outside the source tree, so a run leaves the repository as it found it.

What is new

Most of the diff is shell, and all of it is meant to be run by hand as well as by prow. The scripts do the work; the sequencer only says what order and that the teardown is unconditional.

script	what it does
hack/ci-e2e-aws.sh	the job: run the test, then tear down, always
hack/ci-e2e-aws-run.sh	creates and never removes
hack/ci-e2e-aws-teardown.sh	removes and never creates, idempotent
hack/enable-frr.sh, hack/disable-frr.sh	the FRR lifecycle on the Network CR, with the rollout wait
hack/aws/create-route-servers.sh	one route server, endpoints per AZ, association, propagation
hack/aws/delete-route-servers.sh	the reverse, re-derived each run
hack/aws/list-route-servers.sh	what is actually up
hack/aws/write-e2e-profile.sh	a profile naming the estate that exists now
hack/label-router-nodes.sh	selects the router nodes
hack/delete-e2e-crs.sh	the cluster-side objects a run leaves behind
hack/aws/ensure-cli.sh	an aws CLI new enough for the route server commands

hack/lib/ holds what they share and hack/lib-test.sh tests it with oc and aws stubbed. make ci-e2e-aws, make ci-e2e-aws-teardown and make test-scripts run the job and its tests locally; bin/aws is a file target so a CLI already on PATH is used and nothing is downloaded.

The teardown is written for the case where nobody is watching. It takes the cluster's identity once, before anything is created, and hands it to the teardown, so a cluster that has stopped answering does not take the cloud cleanup down with it. It decides what cluster-side cleanup to attempt on whether the API is reachable rather than on whether INFRA was passed, retries the cloud deletes rather than giving up on a transient failure, falls back to oc where kubectl is absent, and reports what it actually found rather than leaving the sequencer to infer it. A teardown failure decides the job's outcome only when nothing else was wrong, because resources left running are not a pass.

Credentials

The operator runs in the cluster, installed from its bundle by the e2e-aws-operator job, so it has to obtain AWS credentials itself. It asks the SDK first and the cluster second. Where the pod already has credentials, as on ROSA where the pod identity webhook injects them, they are used and the cluster is left alone. Where it has none, the operator creates a CredentialsRequest for itself carrying the nine EC2 actions it uses, and reads the secret the cloud credential operator writes.

What it reads is the credentials key, which is a shared-credentials ini file, rather than aws_access_key_id and aws_secret_access_key. That is the whole reason one code path serves both kinds of cluster: CCO writes that key in every mode it operates in, holding a key pair where the cluster mints and a role ARN plus a token path where it federates, and the AWS SDK already understands both. Token rotation comes free, since the SDK re-reads the token file on each refresh. The profile is pinned to default because that is the only section CCO writes and the SDK would otherwise honour AWS_PROFILE and look for a section the file will never have.

On a cluster that federates the request must carry stsIAMRoleARN and cloudTokenPath or CCO ignores it, so ROLEARN in the environment adds both. OLM sets it from the Subscription, which is what the console writes now that the CSV declares features.operators.openshift.io/token-auth-aws. The deployment projects a bound ServiceAccount token at the path CCO names as web_identity_token_file, with audience openshift rather than the Kubernetes default, because the identity provider ccoctl registers is the cluster's own issuer. The request is reconciled rather than only created, because the role ARN arrives by editing the Subscription long after the operator first asked.

Creating the IAM role itself remains the administrator's job and cannot be otherwise, since the operator has no credentials with which to create a role for itself. The README carries the trust policy and the Subscription stanza.

What is not settled, particularly on ROSA

Two cluster types have been exercised: one that mints, in CI, and one that federates, installed by hand with ccoctl. No part of this has run on ROSA, which is awkward given ROSA HCP is the primary target and the README's IRSA instructions are written for it.

The ambient path is untouched by this change, so a ROSA cluster whose ServiceAccount is annotated with eks.amazonaws.com/role-arn should behave exactly as before: the pod identity webhook injects a token, the SDK resolves it, and the operator asks the cluster for nothing. That is a claim from reading the code, not an observation.

What is genuinely open is that ROSA now has two routes rather than one, and it is not clear which it should use. ROSA is a cluster with credentialsMode Manual and a ServiceAccount issuer, so ROLEARN and a CredentialsRequest carrying stsIAMRoleARN ought to work there too, and would be the more OLM-idiomatic route: no annotating a ServiceAccount that OLM created, and no restarting the operator afterwards. The webhook only injects at pod creation, which is why the README tells you to roll the deployment out after changing anything. Where both are set up the ambient path wins, because the SDK is asked first; that is deterministic but was not a considered decision.

On ROSA HCP specifically, the control plane is hosted off-cluster, and whether the cloud credential operator serves CredentialsRequest objects from the hosted cluster at all has not been checked. If it does not, the annotation route is the only one available there and ROLEARN is irrelevant.

None of this blocks the job or the mint path. It does mean the README's authentication section describes one of two routes, and somebody with a ROSA cluster should decide which one is recommended before this is treated as the documented answer.

Two RBAC problems come with running in the cluster, and neither is visible from a desk, because a manager started against a kubeconfig acts as whoever that kubeconfig is and never exercises its ServiceAccount. Reconciling the request means updating it, and the marker granted create alone. And the operator reads a typed corev1.Secret through the manager's cache, which controller-runtime starts on first use and which was unscoped, so that read asked to list and watch secrets in every namespace while the operator holds a namespaced Role. The informer is now scoped to the operator's own namespace; widening the Role instead would have worked and would have been much worse.

Test plan

The e2e-aws-operator job passes on this branch, which is the first time the whole chain has run: the bundle built here, OLM installing it, the operator in-cluster with no ambient credentials taking the CredentialsRequest path against a minting cluster, and the suite against the estate.

enable-frr  SUCCESS
install     SUCCESS   CSV bgp-cloud-connector.v0.0.1 Succeeded, deployment Available
test        SUCCESS   Ran 5 of 5 Specs in 490.307 seconds
                      SUCCESS! -- 5 Passed | 0 Failed | 0 Pending | 0 Skipped
                      teardown complete

Two availability zones, us-east-1a and us-east-1c, four endpoints, three router nodes, and nothing left behind.

Timings from that run, so it is clear what triggering this costs:

phase	duration
queued before the job started	~39m
job start to FRR enabled (image builds, cluster install)	62m 04s
install the operator from the bundle	1m 17s
test: estate, suite, teardown	13m 02s
gather and deprovision	16m 18s
job total	92m 41s

So about ninety minutes on the clock, plus queueing, of which thirteen are actually testing this change. Almost all the rest is ipi-aws building a cluster from nothing and then destroying it, which no change here affects. The same hack/ci-e2e-aws.sh against a cluster you already have takes about twelve minutes, and gets three availability zones rather than two, so it is the loop to iterate in; this job is the one that proves the bundle, OLM, the ServiceAccount and the RBAC, none of which a workstation can exercise.

The same sequencer was run twice against a hand-built 4.22.10 IPI cluster in us-east-2 with three availability zones, six endpoints and three router nodes, passing 5 Passed | 0 Failed in 413s and 417s, each time leaving no route servers, endpoints, peers, custom resources or namespaces. Three zones is worth having because the presubmit gets two.

The federated path was exercised on a credentialsMode: Manual cluster installed with ccoctl. With no ROLEARN the cloud credential operator ignores the request and marks it provisioned: true with no conditions and no secret, which is why the wait now names ROLEARN. With ROLEARN set the operator updates its existing request, CCO writes the secret, and the SDK parses it and attempts a web identity exchange:

[default]
sts_regional_endpoints = regional
role_arn = arn:aws:iam::...:role/...
web_identity_token_file = /var/run/secrets/openshift/serviceaccount/token

Out of cluster that then fails on the token file, which only exists inside a pod with the projected volume, so the in-pod half of the federated path is the one thing here still taken on trust.

The unit tests cover the resolver directly:

• ambient credentials win, and the cluster is left alone
• a missing secret reads as pending rather than as a fault
• a minted ini yields the right keys
• an STS ini parses to the right role and token path
• the request carries both STS fields with a role ARN, and neither without
• an existing request gains the role ARN without duplicating
• a secret with no credentials key is an error rather than a wait
• the wait names ROLEARN when it is unset, and does not when it is set
• the secret informer is scoped to one namespace, and nothing else is scoped

Individually verified:

• the teardown run three times in a row, converging at 57s, then 4s, then 4s
• the teardown with no cluster reachable, driven by INFRA and AWS_REGION
• a forced test failure still tearing down, and still reporting the test's own exit code
• SIGTERM mid-create tearing down everything it had built
• the full prow path simulated with no aws CLI on PATH, no AWS_PROFILE and no KUBECONFIG, taking credentials from CLUSTER_PROFILE_DIR and the kubeconfig from SHARED_DIR

hack/lib-test.sh covers the shell libraries with oc and aws stubbed and runs in make test-scripts, 55 assertions. Several are regressions for bugs of the same kind: a failed read handing back a plausible answer that the caller then acts on. A failed describe once read as "no route server", which the teardown treats as nothing to do.

Notes for review

Four commits are picked from aws-peer-state, which was never opened as a pull request. They are needed for the suite to pass at all: EC2 refuses a delete on a route server peer that has not finished being created, so E2E-AWS-03 failed on the delete rather than on what it was testing, and the operator miscounted peers EC2 was in the middle of removing. One needed RouterNode.AZ renamed to .Zone, since that rename landed after the branch was written; the commit message says so.

Two smaller things came out of getting this working. go tool kustomize had never built in this tree, which took make install, make deploy and make bundle with it: a .gitignore pattern of coverage.* with no leading slash matches at any depth and had silently excluded two vendored x/text source files that were never tracked. And the suite creates a CUDNBgpConfig, a CUDNBgpRouting and a fixed-name namespace and removed none of them, so a second run against the same cluster failed with namespaces "prod" already exists; the teardown now removes them, before stopping the operator, because both CRs carry finalizers that only the operator clears.

Full details: Stable And Deterministic Test Names

Explanation

PASS. The PR's Ginkgo declarations use static string literals. The final tree contains no titles with pod names, node names, namespaces, IPs, timestamps, UUIDs, or generated identifiers. The diff from main changes test bodies and assertions, but no Ginkgo title lines. The existing titles describe stable behaviors such as peer recreation, node lifecycle, and cleanup.

Full details: Test Structure And Quality

Explanation

The new AWS runner activates Ginkgo tests with two quality violations. In test/e2e/aws/aws_e2e_test.go:255-257, the added cluster-facing Eventually asserts g.Expect(err).NotTo(HaveOccurred()) without a diagnostic message. The AWS suite creates cluster-scoped CUDNBgpConfig, CUDNBgpRouting, and a namespace in the first It block, but it has no AfterEach or AfterAll; cleanup is deferred to a later ordered It block and to external shell teardown. If an earlier ordered spec fails or the suite is run directly, cleanup is not guaranteed. The new runner now executes this suite via make test-e2e-aws, so this pre-existing structure is activated by the pull request.

Resolution

Add a meaningful message to every new assertion, such as "failed to list managed peers while waiting for an available peer". Refactor the AWS Ginkgo suite so each test owns its setup and cleanup through BeforeEach/AfterEach (or a guaranteed Ginkgo cleanup hook). Do not rely on the later E2E-AWS-05 spec or an external shell script to clean cluster-scoped resources after a failed or interrupted spec.

Full details: Microshift Test Compatibility

Explanation

PASS — The PR adds no new Ginkgo e2e nodes. The AWS Context/It declarations are unchanged; the PR only edits an existing test body and suite setup. The added unit tests in internal/platform/aws/aws_test.go use Go testing and AWS mocks, not Ginkgo e2e tests. The added e2e lines introduce no MicroShift-incompatible OpenShift API or namespace references.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The PR adds no new Ginkgo e2e declarations. The base and HEAD contain the same Describe, Context, and It tests. The changed AWS e2e body only waits for an available EC2 peer and verifies replacement state. It does not add a multi-node or HA assumption. The added internal/platform/aws tests are standard Go unit tests, not Ginkgo e2e tests.

Full details: Topology-Aware Scheduling Compatibility

Explanation

No topology-incompatible scheduling constraint was introduced. The PR changes no deployment manifest and no controller scheduling logic. The only production Go change, internal/platform/aws/route_server.go, changes AWS peer lifecycle handling. The existing manager Deployment (config/manager/manager.yaml, replicas: 1) is unchanged, and the new CI manager runs out of cluster. The new worker-label helper selects nodes with the worker label; this also matches nodes that carry both worker and control-plane roles, and it does not add a pod nodeSelector, affinity, topology spread, toleration, or PDB constraint.

Full details: Ote Binary Stdout Contract

Explanation

No OTE stdout contract violation was introduced. The changed Go files add no fmt/log/klog stdout writes, no TestMain or suite teardown output, and no top-level output-producing initializers. The only Printf calls are GinkgoWriter.Printf inside an It block, which the check explicitly allows. BeforeSuite changes use By and file/client setup only. cmd/main.go uses controller-runtime zap logging and has no changed code; the added vendored files have no initialization or stdout writes.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The PR adds no new Ginkgo e2e declarations. The three modified e2e files retain the same 20 It/Describe/Context declarations as main, and the diff adds no Ginkgo declaration, hardcoded IPv4 value, IPv4-only parser, or public URL. Existing AWS EC2 calls are present on both main and HEAD. The added IPv4 literals are in non-Ginkgo unit-test fixtures under internal/platform/aws, so this check is not applicable to them.

Full details: No-Weak-Crypto

Explanation

No weak cryptography was introduced. The pull-request diff from base 668bcac to HEAD contains no MD5, SHA-1, DES, 3DES, RC4, Blowfish, or ECB primitives, crypto APIs, or custom cryptographic implementation. The added AWS credential handling only passes credential-file and profile paths to AWS CLI. The new comparisons cover resource state, ASN, process state, and test results, not secrets or tokens. Existing crypto/tls usage is unchanged and is not a listed weak primitive.

Full details: Container-Privileges

Explanation

No stated privilege condition was introduced. The PR changes no YAML/JSON manifest, Dockerfile, or CI pod definition. An exact scan of added lines found zero instances of privileged:true, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation:true, or root-execution settings. The generated files contain only CUDNBgpConfig and CUDNBgpRouting resources. The existing manager manifests remain unchanged and already use runAsNonRoot:true and allowPrivilegeEscalation:false.

Full details: No-Sensitive-Data-In-Logs

Explanation

The pull request adds CI-visible logging of internal hostnames and network identifiers. hack/ci-e2e-aws-run.sh invokes hack/label-router-nodes.sh, which logs each worker node name at hack/label-router-nodes.sh:48-51; these names can be internal hostnames. The new AWS scripts also print cluster infrastructure names, VPC/subnet IDs, route-server IDs, ENI addresses, and peer addresses. hack/aws/list-route-servers.sh:77 prints the AWS account ID, and hack/aws/list-route-servers.sh:168,172 prints endpoint and peer addresses. hack/run-operator.sh:85-86 forwards manager log lines to stderr on startup failure, which can include node and ENI identifiers. These are changed logging paths that match the custom check's internal-hostname/customer-data condition.

Resolution

Remove sensitive identifiers from CI and general logs. Log only counts, states, and coarse status for worker nodes, endpoints, and peers. Do not print node names, ENI or peer addresses, AWS account IDs, VPC/subnet IDs, or full infrastructure identifiers unless the output is explicitly protected. Do not forward raw manager or AWS/cluster diagnostics to shared logs; scrub them for sensitive values or provide them through a controlled local diagnostic mode.

Separate stderr from the returned VPC ids.

route_server_vpcs folds stderr into out with 2>&1. On a successful call that also writes a warning to stderr, the warning text becomes part of the returned value. The comment at Lines 101-104 describes this exact hazard for aws_query. The consumers act on the value directly: hack/aws/create-route-servers.sh Line 144 compares each field with the cluster VPC, and hack/aws/delete-route-servers.sh Line 287 passes each field to disassociate-route-server --vpc-id.

Capture stderr in a separate file so the NotAssociated check still works.

Report a failed subnet read as a failed read.

The while read loop consumes a process substitution, so the exit status of aws ec2 describe-subnets is discarded. If that call fails, for example on expired credentials, subnets stays empty and Line 105 reports "no private subnets found in ${vpc}".

best-effort so failures from require_cluster or Kubernetes cleanup do not stop
execution under set -e. Ensure teardown continues to stop the operator and
delete route servers when INFRA is set, while preserving the existing cleanup
order.

In `@hack/delete-e2e-crs.sh`:
- Around line 58-78: Guard the oc delete and oc patch calls in delete_and_wait
so non-zero results, including already-missing resources, are recorded without
triggering errexit and the teardown continues to report survivors. Apply the
same failure-tolerant handling to the namespace deletion path near the existing
namespace cleanup, while preserving the current wait, success, and fail
behavior.

In `@hack/stop-operator.sh`:

lines 40-41 by assigning an empty value on failure, then explicitly handle the
empty pgid and remove the pidfile. In hack/run-operator.sh lines 89-91, capture

Do not treat every oc get error as deletion.

gone returns success when oc get fails for any reason. If the API, network, or authorization fails after oc delete is rejected, these paths report successful deletion and skip the wait or failure path. Return success only for NotFound. Propagate other oc get errors.

Also applies to: 110-116

/test e2e-aws

Superseded. This describes an out-of-cluster manager and CRDs applied with make install. The operator is now installed from its bundle by the job, and the current results are in the pull request description.

Status, since the job has been red twice for reasons worth separating from the change itself.

The e2e suite passes in CI. The run against 66abedf7 took a cluster in us-west-1, enabled FRR, built the route server estate, installed the CRDs, started the manager, generated a profile naming the route server it had just created, and ran the suite to 5 Passed | 0 Failed in 421 seconds. Everything this PR sets out to do works in prow, including the route server APIs being permitted in the CI account, which was the main unknown.

Both failures have been assumptions that cannot fail on a workstation. The first was make install applying with kubectl, which the CI image does not carry -- it has oc. Fixed by passing KUBECTL=oc and by defaulting the Makefile to whichever client is present. The second was the teardown waiting for kill -0 to stop reporting the manager alive: it had died on the first TERM, but nothing in the CI container reaps orphans, so it remained a zombie and answered kill -0 until both waits timed out. Fixed in ec8c074b by asking whether the process has finished rather than whether the pid resolves, with a regression test built on a real zombie.

In both failures the teardown still removed the AWS estate correctly, including in the run that failed before the CRDs were installed. Nothing has leaked in any run.

A third run is in flight against ec8c074b.

Poll for the zombie state instead of using a fixed delay.

Line 220 waits 300 ms after SIGKILL, but it does not guarantee that the child has exited and become unreaped. kill -0 at Line 231 also succeeds while the child is still live. A scheduling delay can therefore make process_finished return 1 and fail this test even when the helper is correct. Publish the PID immediately, then poll kill -0 and process_finished with a bounded timeout before asserting.

Some comments you may want to address

Otherwise looks pretty good 🥳

[jpinsonneau]

We should probably bump timeout at least to 60m here as peerSettleTimeout takes already 15m + reconcileTimeout = 6m 🤔

WDYT ?

[jpinsonneau]

Avoid returning stderr into out like aws_query does:

Suggested change

	route_server_vpcs() {
	local out
	if out="$(aws ec2 get-route-server-associations --route-server-id "$1" \
	--query 'RouteServerAssociations[].VpcId' --output text 2>&1)"; then
	printf '%s' "${out}"
	return 0
	fi
	case "${out}" in
	*NotAssociated*) return 0 ;;
	esac
	warn "cannot read associations for $1"
	warn " ${out}"
	return 1
	}
	route_server_vpcs() {
	local out err_file
	err_file="$(mktemp)"
	if out="$(aws ec2 get-route-server-associations --route-server-id "$1" \
	--query 'RouteServerAssociations[].VpcId' --output text 2>"${err_file}")"; then
	rm -f "${err_file}"
	printf '%s' "${out}"
	return 0
	fi
	local captured
	captured="$(cat "${err_file}")"; rm -f "${err_file}"
	case "${captured}" in
	*NotAssociated*) return 0 ;;
	esac
	warn "cannot read associations for $1"
	warn " ${captured}"
	return 1
	}

[jpinsonneau]

Capture first and iterate the captured value to avoid loosing describe-subnets exit status:

Suggested change

	subnets=()
	seen_azs=""
	while read -r subnet az; do
	[[ -n "${subnet}" ]] || continue
	case " ${seen_azs} " in *" ${az} "*) continue ;; esac
	seen_azs="${seen_azs} ${az}"
	subnets+=("${subnet}:${az}")
	done < <(aws ec2 describe-subnets \
	--filters "Name=vpc-id,Values=${vpc}" "Name=tag:Name,Values=*private*" \
	--query 'Subnets[].[SubnetId,AvailabilityZone]' --output text | sort -k2)
	subnets_raw="$(aws_query "list private subnets in ${vpc}" \
	aws ec2 describe-subnets \
	--filters "Name=vpc-id,Values=${vpc}" "Name=tag:Name,Values=*private*" \
	--query 'Subnets[].[SubnetId,AvailabilityZone]' --output text)" \
	|| die "cannot list the subnets in ${vpc}"
	subnets=()
	seen_azs=""
	while read -r subnet az; do
	[[ -n "${subnet}" ]] || continue

Should we also handle other states like failed to avoid creating duplicates / skipping deletions ?
