AWS EventBridge PutEvents API response FailedEntryCount HTTP 200 official documentation
💡 Result:
Yes. **HTTP 200 does not necessarily mean every event was accepted.** The `PutEvents` API reference says a successful API action returns HTTP 200, while `FailedEntryCount` reports how many individual entries failed. Check each item in `Entries`: successful ones have an `EventId`; failures have `ErrorCode` and `ErrorMessage`. ([docs.aws.amazon.com](https://docs.aws.amazon.com/eventbridge/latest/APIReference/API_PutEvents.html?utm_source=openai))
AWS’s user guide shows a response with `FailedEntryCount: 1` for a partially failed request and says to retry unsuccessful entries. It also notes an important exception: publishing to a nonexistent event bus can still return 200 without increasing `FailedEntryCount`; the event is dropped. ([docs.aws.amazon.com](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-putevents.html?utm_source=openai))

Handle EventBridge partial failures.
check propagates errors from execute, but PutEvents can return HTTP 200 with FailedEntryCount greater than zero. This function then returns nil and discards the failure details. Check FailedEntryCount and handle failed entries. Checking only the HTTP status is not enough. Alternatively, return the response and require callers to inspect it.
Return the response for callers to inspect

Avoid placing the database password in the command line.
If users replace <db-password> with a real value, an interactive Bash session can retain the command in shell history. Use a protected file with --secret-string file://... instead. AWS CLI supports this input form, and Bash can save command history to $HISTFILE. (gnu.org)

AWS EC2 IMDSv2 hop limit 2 containers sibling containers access instance profile credentials restrict container access IMDS
💡 Result:
**IMDSv2 hop limit 2 is not a container-access restriction.** It allows an IMDSv2 token response to traverse an extra network hop, which may be needed for containers to reach IMDS. AWS recommends `HttpTokens=required` and hop limit `2` for container-hosting instances—but containers that can reach IMDS may still obtain the **instance-profile credentials**. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html?utm_source=openai))
If your goal is to **prevent containers from accessing the instance profile**, block traffic to IMDS from containers at the container/network layer and give workloads their own scoped credentials. For ECS on EC2, AWS recommends task IAM roles and documents these controls:
- **Bridge mode:** add a host firewall rule to drop container-forwarded traffic to `169.254.169.254`.
- **`awsvpc` mode:** set `ECS_AWSVPC_BLOCK_IMDS=true` in `/etc/ecs/ecs.config`.
- **Host network mode:** set `ECS_ENABLE_TASK_IAM_ROLE_NETWORK_HOST=false` in the ECS agent configuration.
These ECS settings are mode-specific; hop limit 1 is not a general substitute for blocking access. ([docs.aws.amazon.com](https://docs.aws.amazon.com/us_eg/AmazonECS/latest/bestpracticesguide/security-iam-roles.html?utm_source=openai))
For **sibling-container isolation**, don’t assume IMDS settings alone provide it: AWS warns that containers on ECS EC2 aren’t a security boundary and may access credentials or data from co-located tasks. Use least-privilege task roles; for stricter isolation, consider dedicated instances or Fargate. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-iam-roles.html?utm_source=openai))

site:docs.aws.amazon.com EC2 IMDSv2 hop limit 2 containers sibling containers instance profile credentials block IMDS access isolation ECS security boundary
💡 Result:
**A hop limit of 2 is not a container-isolation boundary.** AWS recommends it for IMDSv2 in container environments because a limit of 1 can prevent containers from receiving the token response. So raising it to 2 can enable container access to IMDS; it does not isolate sibling containers or tasks. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-IMDS-new-instances.html))
For **ECS on EC2**, AWS explicitly recommends blocking container access to IMDS to protect the instance-profile credentials, and recommends task IAM roles for application permissions. The specific blocking method depends on network mode: AWS documents iptables for `bridge`, `ECS_AWSVPC_BLOCK_IMDS=true` for `awsvpc`, and disabling `ECS_ENABLE_TASK_IAM_ROLE_NETWORK_HOST` for `host` networking. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/security-iam-roles.html))
AWS also warns that ECS on EC2 does **not** provide task isolation: containers on the same instance may access other tasks’ credentials or data. For sensitive workloads, AWS recommends dedicated instances. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/security-shared-model.html))

Warn about sibling-container access to IMDS.
A sibling container with a network path to IMDS that host or container controls do not block may also obtain the instance-profile credentials. Hop limit 2 does not isolate containers. Isolate this workload or restrict sibling containers’ IMDS access. AWS documents IMDS-blocking controls for ECS on EC2 and recommends dedicated instances for sensitive ECS workloads.
🐛 Suggested fix
:::note
If the integration runs in a container on the instance and IMDSv2 is enforced, set the metadata hop limit to `2`. Otherwise the container cannot reach the metadata service:
```bash
aws ec2 modify-instance-metadata-options \
--instance-id <instance-id> \
--http-put-response-hop-limit 2 \
--http-tokens required
```
+
+If other containers share this instance, they may also obtain the instance-profile credentials if their network path to IMDS is not blocked. Isolate this workload or restrict sibling containers' IMDS access with host or container network controls. AWS documents [IMDS-blocking controls for ECS on EC2](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/security-iam-roles.html) and recommends [dedicated instances for sensitive ECS workloads](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/security-shared-model.html).

Purpose
The AWS connectors now share one authentication model (
ballerinax/aws.auth), so they can use IAM roles on AWS instead of access keys. WSO2 Integrator's AWS support was spread across pages with no single entry point, and parts of it were out of date: the AWS Secrets Manager section in Secrets and Encryption imported a module that doesn't exist (ballerinax/aws.secretsmanager) and used the old credential fields.Goals
Approach
Each topic goes into the section where it belongs in the new IA, and a new hub page links to all of them.
docs/aws.md(/aws): top-level hub page with tiles for Build, Deploy, and Secure and run, plus tiles for every AWS connector. It appears in the left nav right after Deploy and Run (sidebar_position: 6.5). Its icon comes from a newawsentry insrc/theme/DocSidebar/Desktop/icons.tsx.deploy-and-run/secure/aws-access.md: the default credential chain, attaching IAM roles (ECS task role, EKS Pod Identity and IRSA, EC2 instance profile, Lambda execution role), cross-accountAssumeRole, the other credential sources, SigV4 signing for AWS APIs without a connector, VPC endpoints and FIPS/dual-stack endpoints, and troubleshooting.containerized-deployment.md: new "Amazon ECS deployment" section (ECR, task and execution roles, Secrets Manager and SSM injection asBAL_CONFIG_VAR_*, CloudWatch Logs).secrets-encryption.md: rewrote the AWS Secrets Manager section to cover injecting secrets at startup (ECS task definition, EKS External Secrets Operator) and reading them at runtime with the currentaws.secretmanagerAPI.serverless-deployment.md: Lambda event type table and execution role permissions.vm-deployment.md: "Run on Amazon EC2" (instance profile, IMDSv2 hop limit).observe/logging.md,tracing.md,metrics.md: CloudWatch Logs, AWS X-Ray through an ADOT collector, and Amazon Managed Service for Prometheus.Connector links use the production cross-product path (
/integration-platform/docs/connectors/catalog/...), matching the navbar's Connectors link, and point at the page IDs in thewso2-connectorssidebar.
