# Splunk Cloud Acs Admin Setup

> Use when the user asks to manage Splunk Cloud ACS, acs admin, ACS indexes, ACS HEC tokens, ACS users and roles, app permissions, private connectivity, outbound ports, DDSS, ACS limits, maintenance windows, restart current-stack, ACS license state, Observability pairing, or to audit Splunk Cloud control-plane configuration. Render, preflight, inventory, apply, audit, and validate Splunk Cloud Admin Config Service (ACS) administration across IP allowlists, indexes, HEC tokens, users, roles, capabilities, app permissions, private connectivity, outbound ports, DDSS self-storage, limits.conf settings, maintenance windows, restarts, apps, authentication tokens, deployment task status, license state, and Observability pairing handoffs.

# Splunk Cloud ACS Admin Setup

## Prerequisites

| Tool or access | Purpose | Verify |
|---|---|---|
| Bash and Python 3 | Run bundled setup and validation helpers | `bash --version && python3 --version` |
| Required product/platform access | Inspect or configure the selected target | Complete the documented preflight |
| Credential files for live modes | Keep secrets out of chat | Verify paths only |

## Workflow Overview

```text
┌───────────┐   ┌───────────────┐   ┌───────────────┐   ┌─────────────────┐
│ Preflight │ → │ Render/review │ → │ Apply/handoff │ → │ Validate evidence │
└───────────┘   └───────────────┘   └───────────────┘   └─────────────────┘
```

## When to Activate

- Manage Splunk Cloud ACS, acs admin, ACS indexes, ACS HEC tokens, ACS users and roles, app permissions, private
  connectivity, outbound ports, DDSS, ACS limits, maintenance windows, restart current-stack, ACS license state,
  Observability.
- Preview and review the splunk cloud acs admin setup workflow before any live apply phase.
- Diagnose failed prerequisites, generated assets, configuration, or validation evidence.

## Scope

Follow the documented read-only or render-first path whenever it is available.
This skill does not imply permission to mutate live systems. Require explicit
apply flags, protected credentials, and operator review for state changes.

## Examples

Inspect the supported setup modes before selecting one:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/setup.sh --help
```

Expected output: usage, supported modes, and required arguments are displayed
without changing the target environment.

Inspect validation modes before running completion checks:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/validate.sh --help
```

Expected output: offline, live, and completion options are displayed when the
skill supports them; help exits without mutation.

## Troubleshooting

| Issue | Cause | Resolution |
|---|---|---|
| Preflight fails | A required tool or access path is missing | Resolve it before rendering or applying |
| Rendered assets are incomplete | Required non-secret inputs are absent | Complete intake and render again |
| Apply is blocked | Review, credentials, or explicit acceptance is missing | Use the documented handoff |
| Validation is incomplete | Live evidence is unavailable | Record the gap and keep completion open |

This skill is the broad Splunk Cloud Admin Config Service workflow. It replaces
the older allowlist-only workflow while preserving the proven IPv4/IPv6
allowlist convergence logic and lock-out protection.

Cloud Platform planning defaults to **10.5.2605**, with **10.4.2604** as the
previous train. Use the train-specific canonical sources in `reference.md`
when reviewing an ACS operation.

## Agent Behavior

Never paste subnet lists, JWT tokens, stack identifiers, passwords, or HEC token
values into chat. The skill reads stack context from the project credentials
file (`STACK_TOKEN`, `STACK_TOKEN_USER`, `SPLUNK_CLOUD_STACK`, `ACS_SERVER`) and
reads non-secret desired state from CLI flags or a local JSON admin plan. Every
render requires an explicit `--target-stack`; it must match the selected
credential context before a rendered live helper will run.

Prefer `--phase render` or `--phase preflight` first. Only run `--phase apply`
after the operator has reviewed rendered assets. Broad ACS admin mutations are
guarded inside `apply-admin-plan.sh` and require
`ACCEPT_ACS_ADMIN_MUTATION=true`.

## Quick Start

Render a full ACS admin packet and allowlist plan:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/setup.sh \
  --phase render \
  --target-stack STACK_NAME \
  --admin-plan-file acs-admin-plan.json \
  --features search-api,s2s,hec \
  --search-api-subnets 198.51.100.0/24 \
  --s2s-subnets 198.51.100.0/24,203.0.113.0/24 \
  --hec-subnets 203.0.113.0/24
```

Render an inventory-only packet for the broader ACS surface:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/setup.sh \
  --phase render \
  --target-stack STACK_NAME \
  --modules indexes,hec-tokens,users,roles,capabilities,app-permissions,outbound-ports,ddss,limits,maintenance-windows,restarts,license,observability
```

Audit live allowlist state against the rendered plan:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/setup.sh \
  --phase audit --target-stack STACK_NAME
```

Apply reviewed allowlist and admin operations:

```bash
ACCEPT_ACS_ADMIN_MUTATION=true \
bash skills/splunk-cloud-acs-admin-setup/scripts/setup.sh \
  --phase apply \
  --target-stack STACK_NAME \
  --admin-plan-file acs-admin-plan.json
```

Validate rendered assets without live mutation:

```bash
bash skills/splunk-cloud-acs-admin-setup/scripts/validate.sh
```

## What It Renders

Under `splunk-cloud-acs-admin-rendered/acs-admin/`:

- `plan.json` - desired allowlist state plus reviewed ACS admin operations.
- `preflight.sh` - ACS context, command-surface, capability, FedRAMP, lock-out,
  subnet-limit, and drift checks.
- `inventory.sh` - read-only live inventory across the selected ACS modules.
- `apply-ipv4.sh` and `apply-ipv6.sh` - converge IP allowlists.
- `apply-admin-plan.sh` - guarded executor for non-secret admin operations.
- `admin-commands.sh` - review-only command catalog for every planned operation.
- `private-connectivity-rest.sh` - REST helper for ACS private connectivity,
  which is API-only in some ACS CLI releases.
- `wait-for-ready.sh` - polls ACS status until the stack reports `Ready`.
- `audit.sh` - snapshots allowlists and verifies live state matches the plan.
- `terraform-snippets.tf` - optional `splunk/scp` provider snippets for IPv4
  allowlists when `--emit-terraform true`.

## Safety Defaults

- `STRICT_DRIFT=true` refuses allowlist apply if live state drifted from the
  rendered plan. Pass `--force` only after reviewing the diff.
- The `acs` allowlist feature requires operator IP coverage unless
  `--allow-acs-lockout true` is explicitly set.
- User password operations and custom HEC token values are blocked from
  automation because the current ACS CLI takes those values as argv. Use a
  file-backed handoff instead.
- Private connectivity uses ACS REST endpoints (`private-connectivity/eligibility`
  and `private-connectivity/endpoints`) because the local ACS CLI might not
  expose a matching command group. These Bearer-authenticated calls use the
  shared HTTPS-only, no-redirect, no-globbing ACS REST helper and ignore user
  curl configuration.
