+# Overview
+
+This action provisions an Intel Gaudi 3 accelerated instance on IBM Cloud VPC using the RHEL AI image. The instance uses the `gx3d-160x1792x8gaudi3` profile (160 vCPU, 1792 GB RAM, 8x Gaudi 3 accelerators) and is assigned a floating IP for direct SSH access.
+
+Two networking modes are supported:
+
+- **Existing subnet** (`--subnet-id`): the instance is placed in a pre-existing VPC subnet. VPC, subnet, and gateway are not created. Only `IC_REGION` is required.
+- **Auto-provision** (no `--subnet-id`): a new VPC, subnet, and public gateway are created from scratch. Both `IC_REGION` and `IC_ZONE` are required.
+
+## Environment variables
+
+| Variable | Required | Description |
+|---|---|---|
+| `IBMCLOUD_ACCOUNT` | yes | IBM Cloud account ID |
+| `IBMCLOUD_API_KEY` | yes | IBM Cloud API key |
+| `IC_REGION` | yes | IBM Cloud region (e.g. `us-east`, `us-south`, `eu-de`) |
+| `IC_ZONE` | only without `--subnet-id` | Availability zone (e.g. `us-east-1`) |
+| `IBMCLOUD_COS_ACCESS_KEY_ID` | only with S3 `--backed-url` | HMAC access key for IBM Cloud Object Storage |
+| `IBMCLOUD_COS_SECRET_ACCESS_KEY` | only with S3 `--backed-url` | HMAC secret key for IBM Cloud Object Storage |
+| `IBMCLOUD_COS_ENDPOINT` | no | COS S3 endpoint (defaults to `s3.<region>.cloud-object-storage.appdomain.cloud`) |
+
+## Regional availability
+
+Gaudi 3 instances are available in:
+
+- **us-east** (Washington DC)
+- **us-south** (Dallas)
+- **eu-de** (Frankfurt)
+
+## Create
+
+```bash
+mapt ibmcloud ibm-gaudi create -h
+create
+
+Usage:
+  mapt ibmcloud ibm-gaudi create [flags]
+
+Flags:
+      --conn-details-output string           path to export host connection information (host, username and privateKey)
+  -h, --help                                 help for create
+      --otel-app-code string                 OpenTelemetry appcode identifier (e.g. MAPT-001); when set together with --otel-auth-token, installs the otelcol-contrib filelog collector on the instance
+      --otel-auth-token string               OpenTelemetry authentication token (UUID) used to authenticate against the OTLP endpoint
+      --otel-endpoint string                 OTLP HTTP endpoint to export logs to (default "https://otel-input.corp.redhat.com")
+      --otel-index string                    Splunk index name for log routing (e.g. rh_linux)
+      --subnet-id string                     ID of an existing VPC subnet to deploy the instance into (optional)
+      --tags stringToString                  tags to add on each resource (--tags name1=value1,name2=value2) (default [])
+
+Global Flags:
+      --backed-url string     backed for stack state. (local) file:///path/subpath (s3) s3://existing-bucket, (azure) azblob://existing-blobcontainer. See more https://www.pulumi.com/docs/iac/concepts/state-and-backends/#using-a-self-managed-backend
+      --debug                 Enable debug traces and set verbosity to max. Typically to get information to troubleshooting an issue.
+      --debug-level uint      Set the level of verbosity on debug. You can set from minimum 1 to max 9. (default 3)
+      --project-name string   project name to identify the instance of the stack
+```
+
+### Outputs
+
+Files written to the path defined by `--conn-details-output`:
+
+| File | Description |
+|---|---|
+| `host` | Floating IP of the instance (direct SSH) |
+| `username` | SSH username (`root`) |
+| `id_rsa` | Private key for the instance |
+
+A state folder is also created at `--backed-url`. It is required (together with `--project-name`) to destroy the resources later.
+
+### SSH access
+
+```bash
+OUTPUT=/path/to/conn-details-output
+
+ssh -i ${OUTPUT}/id_rsa \
+    -o StrictHostKeyChecking=no \
+    root@$(cat ${OUTPUT}/host)
+```
+
+### Container
+
+```bash
+# Using an existing VPC subnet
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IC_REGION=us-east \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi create \
+            --project-name ibm-gaudi \
+            --backed-url file:///workspace \
+            --conn-details-output /workspace \
+            --subnet-id <subnet-id>
+
+# Auto-provisioning VPC, subnet, and gateway
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IC_REGION=us-east \
+        -e IC_ZONE=us-east-1 \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi create \
+            --project-name ibm-gaudi \
+            --backed-url file:///workspace \
+            --conn-details-output /workspace
+```
+
+## OpenTelemetry log collection
+
+When both `--otel-app-code` and `--otel-auth-token` are provided, cloud-init installs `otelcol-contrib` on the instance at first boot and configures it to ship `/var/log/messages`, `/var/log/secure`, and `/var/log/audit/audit.log` to the OTLP endpoint.
+
+```bash
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IC_REGION=us-east \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi create \
+            --project-name ibm-gaudi \
+            --backed-url file:///workspace \
+            --conn-details-output /workspace \
+            --subnet-id <subnet-id> \
+            --otel-app-code MAPT-001 \
+            --otel-auth-token <uuid-token>
+```
+
+## Using IBM Cloud Object Storage as S3 backend
+
+To store Pulumi state in IBM COS instead of a local file, create [HMAC credentials](https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-uhc-hmac-credentials-main) for your COS instance and pass an `s3://` backed URL:
+
+```bash
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IBMCLOUD_ACCOUNT=XXX \
+        -e IC_REGION=us-east \
+        -e IC_ZONE=us-east-1 \
+        -e IBMCLOUD_COS_ACCESS_KEY_ID=XXX \
+        -e IBMCLOUD_COS_SECRET_ACCESS_KEY=XXX \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi create \
+            --project-name ibm-gaudi \
+            --backed-url s3://my-cos-bucket \
+            --conn-details-output /workspace
+```
+
+## Destroy
+
+```bash
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IC_REGION=us-east \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi destroy \
+            --project-name ibm-gaudi \
+            --backed-url file:///workspace
+```
+
+By default, destroy removes the Pulumi state files from the backend after a successful destroy. Use `--keep-state` to preserve them:
+
+```bash
+podman run -d --name ibm-gaudi \
+        -v ${PWD}:/workspace:z \
+        -e IBMCLOUD_API_KEY=XXX \
+        -e IBMCLOUD_ACCOUNT=XXX \
+        -e IC_REGION=us-east \
+        -e IBMCLOUD_COS_ACCESS_KEY_ID=XXX \
+        -e IBMCLOUD_COS_SECRET_ACCESS_KEY=XXX \
+        quay.io/redhat-developer/mapt:latest ibmcloud ibm-gaudi destroy \
+            --project-name ibm-gaudi \
+            --backed-url s3://my-cos-bucket \
+            --keep-state
+```
