Adding Gateway performance test scripts - #3230
Conversation
📝 WalkthroughWalkthroughThis change adds an EKS-based API Gateway performance framework. It provisions infrastructure, deploys gateway APIs and a mock backend, runs distributed JMeter scenarios, processes results, and optionally publishes results through pull requests. ChangesAPI Gateway EKS performance testing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new performance-testing stack can currently execute unsafe input, expose credentials and SSH keys, leak AWS resources, fail during normal configurations, and publish misleading baseline results. It is not ready to merge until the security, cleanup, execution, and measurement issues are fixed or explicitly accepted by the owners. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@gateway/perf/api-gateway-eks-perf/cleanup.sh`:
- Around line 55-58: Update the EKS deletion block to reflect that eksctl delete
cluster runs synchronously with --wait, changing the start and completion
messages accordingly. Remove stderr suppression while preserving the trap’s
non-fatal behavior, so deletion errors remain visible in the Jenkins log without
aborting cleanup.
In `@gateway/perf/api-gateway-eks-perf/create-jmeter-ec2s.sh`:
- Around line 121-133: Make the STATE_FILE durable throughout resource creation:
in gateway/perf/api-gateway-eks-perf/create-jmeter-ec2s.sh lines 121-133,
persist each identifier immediately after its AWS call returns rather than
writing the complete file only at the end. In
gateway/perf/api-gateway-eks-perf/cleanup.sh lines 62-65, track success across
every cleanup step and remove STATE_FILE only when all steps succeed, preserving
it for recovery after any failure.
Apply the same fix in `@gateway/perf/api-gateway-eks-perf/cleanup.sh` around lines
62 - 65.
- Around line 49-52: Restrict the SSH ingress rule in the EC2 setup flow from
0.0.0.0/0 to a parameterized Jenkins slave CIDR, defaulting that value to the
slave address, and pass it to the --cidr option used by the
authorize-security-group-ingress command.
In `@gateway/perf/api-gateway-eks-perf/eks-cluster-perf.yaml.template`:
- Around line 18-29: Update the EKS_GATEWAY_NODE_DESIRED value used by the
gateway-ng managedNodeGroups configuration to equal GATEWAY_RUNTIME_REPLICAS
plus one, ensuring capacity for the gateway controller alongside runtime
replicas. Keep the existing desired-capacity variable wiring intact and avoid
relying on backend-ng scheduling.
In `@gateway/perf/api-gateway-eks-perf/publish-results-pr.sh`:
- Around line 32-37: Before the clone in the publish-results flow, configure
temporary Git HTTPS authentication when GH_TOKEN is set, so git clone and git
push can use the token; preserve existing gh authentication behavior and ensure
the temporary credential configuration is cleaned up after the script completes.
- Around line 57-61: After the sparse-checkout setup, update the results
repository flow to detect whether RESULTS_PR_BRANCH exists on origin, fetch it,
and check it out before rendering the README. Ensure rendering and the TEST_ID
check use that existing branch, while preserving the base-branch path when it
does not exist; avoid recreating the local branch from RESULTS_PR_BASE in the
existing-branch case so subsequent pushes remain fast-forwardable.
In `@gateway/perf/api-gateway-eks-perf/run-api-gateway-eks-tests.sh`:
- Around line 468-470: Remove the use of SSH_KEY in the client-to-server setup
around scp_cmd and ssh_cmd; generate or import a per-run, short-lived dedicated
key for JMeter server access, use it for the RMI connection, and ensure it is
deleted from the client during cleanup.
- Around line 66-86: Harden sanitize_run_perf_opts by allow-listing only
documented flags and strictly validated values, rejecting shell metacharacters
and unsupported tokens before RUN_PERF_OPTS reaches the remote heredoc. Handle
both separated and attached forms of the matrix flags (-n/-m/-j/-k/-l/-r,
including -n2 and -n=2) so they are removed consistently without allowing
command injection.
In `@gateway/perf/performance-test-scripts/api-gateway/config.perf-overlay.toml`:
- Around line 31-37: Remove the hardcoded admin user entry from
gateway/perf/performance-test-scripts/api-gateway/config.perf-overlay.toml lines
31-37, leaving credentials to an explicit local overlay. In
gateway/perf/performance-test-scripts/api-gateway/eks/eks-common.sh lines
443-450, update eks_write_generated_values to require the username from
environment configuration, generate a password when unset, and write only its
hash with password_hashed: true.
In `@gateway/perf/performance-test-scripts/api-gateway/eks/backend-mock-eks.yaml`:
- Around line 29-41: Update the JVM heap argument in the backend mock EKS
container configuration from 4g to 3g, keeping it below the existing 4Gi memory
limit and preserving the current resource settings.
In
`@gateway/perf/performance-test-scripts/api-gateway/eks/deploy-apis-eks-minimal.sh`:
- Around line 30-31: Update the credential setup in the deployment script to
require GATEWAY_MGMT_USER and GATEWAY_MGMT_PASS explicitly, removing the admin
defaults and avoiding construction of a user:password auth value. Add a
mgmt_curl helper that supplies curl credentials through a temporary config on
stdin, then replace each curl invocation using -u, including the calls around
the management API requests, with mgmt_curl while preserving their other options
and behavior.
- Around line 46-63: Update the API-list parsing in the deployment script to
avoid process substitution: parse the management API response into a variable
first, check Python’s exit status, and fail before deletion when parsing fails.
Make the parser handle both object responses containing apis/items and top-level
JSON arrays, while preserving the existing api_names and api_count flow for
valid responses.
In `@gateway/perf/performance-test-scripts/api-gateway/eks/env.eks.example`:
- Line 37: Update the sizing exports in the environment example, including
GATEWAY_RUNTIME_REPLICAS, controller CPU and memory limits, and runtime CPU and
memory limits, to use the ${VAR:-default} form so pre-existing operator or
Jenkins values are preserved while retaining current defaults.
- Line 31: Update the default value assigned by EKS_K8S_VERSION to a currently
supported Kubernetes version, replacing the outdated 1.29 fallback while
preserving the environment-variable override behavior.
In `@gateway/perf/performance-test-scripts/api-gateway/eks/install-gateway.sh`:
- Around line 72-77: Redirect the progress message emitted by
eks_wait_runtime_lb to stderr so its command substitution captures only the
runtime load balancer hostname. Update the relevant output in
eks_wait_runtime_lb while preserving the existing hostname output and the
caller’s Gateway runtime URL and GATEWAY_HOST behavior.
In `@gateway/perf/performance-test-scripts/jmeter/generate-jwt-tokens.sh`:
- Around line 23-28: Update the curl invocation in the token-generation flow to
avoid placing client_secret in command-line arguments; pass the OAuth
credentials through stdin or a curl config mechanism instead. Also enforce
restrictive permissions on ${HOME}/jwt-tokens.csv immediately after each
truncation, including both file-initialization paths, so generated bearer tokens
are not readable by other users.
- Around line 40-42: Update the gateway user initialization near gw_user to
safely handle an unset GATEWAY_SSH under set -u, allowing the existing ec2-user
fallback to execute; preserve the current GATEWAY_SCP_USER precedence and leave
the gw_host handling unchanged.
In `@gateway/perf/performance-test-scripts/jmeter/run-scenario.sh`:
- Around line 107-122: Replace the stale ai-gateway-manual directory prefix in
both remote cd commands within run-scenario.sh’s backend start/reconfigure flow,
using the configured performance-test directory. Also update
generate-jwt-tokens.sh’s remote cd command to use the same intended directory,

107-122 and gateway/perf/performance-test-scripts/jmeter/generate-jwt-tokens.sh
lines 53-58.
- Around line 306-331: Update preflight_jmeter_disk so every post-prune
free-space measurement and threshold check uses the filesystem containing
PERF_HOME, matching its initial availability check instead of df /. Apply the
same target-filesystem substitution in backup_previous_results, while preserving
the existing cleanup, warnings, and failure thresholds.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Do not suppress eksctl delete cluster errors, and align the messages with --wait.
Two problems exist here:
- The messages state the deletion "runs async" and is only "initiated".
--waitmakeseksctlblock until deletion completes, so both messages are wrong. 2>/dev/null || truediscards all error output. If the deletion fails, an EKS cluster and its node groups stay running and no diagnostic appears in the Jenkins log. That is a silent cost leak.
Keep the trap non-fatal, but surface the failure.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Restrict SSH ingress to the Jenkins slave address.
The rule opens port 22 to 0.0.0.0/0. The instances receive public IP addresses (line 84), so the SSH service is reachable from the whole internet for the duration of the run. Key-based authentication limits the exposure, but the open port still invites credential-stuffing traffic and password-guessing noise on a public AMI.
Only the Jenkins slave needs SSH access. Parameterize the CIDR and default it to the slave address.

The state-file lifecycle is not failure-safe, so AWS resources can leak. STATE_FILE is the only record that cleanup.sh uses to discover the security group and the EC2 instances. The producer writes it only after every AWS call succeeds, and the consumer deletes it even when cleanup fails. Both ends must treat the file as durable failure-recovery state.
gateway/perf/api-gateway-eks-perf/create-jmeter-ec2s.sh#L121-L133: write each identifier toSTATE_FILEas soon as AWS returns it, instead of writing the complete file at the end.gateway/perf/api-gateway-eks-perf/cleanup.sh#L62-L65: track whether every cleanup step succeeded, and removeSTATE_FILEonly in that case.

desiredCapacity does not reserve a node for the gateway controller.
EKS_GATEWAY_NODE_DESIRED is set to GATEWAY_RUNTIME_REPLICAS in gateway/perf/api-gateway-eks-perf/run-api-gateway-eks-tests.sh (line 232), which defaults to 1. The shared contract in gateway/perf/performance-test-scripts/api-gateway/eks/env.eks.example uses EKS_NODE_DESIRED=$((replicas + 1)) and documents "at least one per runtime replica (controller shares a node)".
With one node, the gateway runtime pod (4 CPU limit) and the gateway controller pod (1 CPU limit) share the same node. Controller activity then competes with the runtime for CPU and skews the throughput and latency numbers that this stack publishes as baselines.
Set the gateway node group capacity to replicas + 1, or confirm that the controller is scheduled onto backend-ng.

Configure Git authentication when GH_TOKEN is the only credential.
GH_TOKEN authenticates gh, but HTTPS git clone and git push do not consume it automatically. Without a Jenkins Git credential helper, the script cannot push the results branch.
Configure a temporary Git credential helper or use a Jenkins Git credential binding before the clone.

The OAuth client secret is exposed in the process list.
--data-urlencode "client_secret=${client_secret}" places the secret in the curl argv. Any local user can read it from /proc or ps while the request runs. The loop on lines 92-95 repeats this up to 500 times per run, so the exposure window is long on a shared perf host.
Pass the credentials through stdin instead. Also restrict the permissions on the token file, because ${HOME}/jwt-tokens.csv holds usable bearer tokens and is created with the default umask.

set -u makes the ec2-user fallback unreachable and aborts the run.
Line 11 enables set -u. When GATEWAY_SCP_USER is unset, the shell evaluates the default branch ${GATEWAY_SSH%%@*}. env.jmeter.api.example never defines GATEWAY_SSH; it defines BACKEND_SSH and BACKEND_SSH_KEY. The expansion then fails with GATEWAY_SSH: unbound variable and the script exits. The ec2-user fallback on line 41 never runs.
This path is reached on the default EKS configuration: no JWT_OAUTH_TOKEN_URL and port 8088 unreachable send line 114 into this function. The || true on line 114 does not contain an unbound-variable exit.

Remote commands use the stale ai-gateway-manual directory prefix. Three remote ssh commands cd into ai-gateway-manual subdirectories. This cohort places its scripts under performance-test-scripts, and PERF_HOME defaults to perf-api-gateway-manual. The prefix looks carried over from the AI-gateway variant of these scripts. Each failure is swallowed: run-scenario.sh falls back to a warning and continues with an unconfigured backend, and generate-jwt-tokens.sh reports a generic unreachable-gateway error. Confirm the intended directory and correct all three commands. The verification script on the run-scenario.sh comment locates the real paths.

preflight_jmeter_disk measures the wrong filesystem for every threshold.
Line 308 measures free space on PERF_HOME. Every threshold check after the prune step measures df / instead (lines 317, 322, 324, 328). If PERF_HOME sits on a separate volume, the results are wrong in both directions. A full results volume with a healthy root passes the check, and the run later fails on a write error. A full root with a healthy results volume triggers the deletion of results/ and aborts a valid run. The hint on line 329 to "expand EBS" confirms that a separate volume is an expected setup.
Measure one target consistently. backup_previous_results (line 337) has the same problem.
