Elasticache Datastore Bootstrap
One-shot bootstrap for @webframp/valkey-datastore targeting AWS ElastiCache Serverless (Valkey). Creates a serverless cache, a VPC security group for access, and a least-privilege IAM managed policy, then switches the current swamp repository to the Valkey datastore.
Prerequisites
- AWS credentials with permissions to create ElastiCache serverless caches, EC2 security groups, and IAM managed policies
- A VPC with at least one subnet (the cache is deployed into the default VPC unless overridden)
What it does
provisioncreates an ElastiCache Serverless cache (Valkey engine, TLS enabled), a security group allowing inbound on port 6379 from the caller's VPC CIDR, and a scoped IAM managed policy.- A final
command/shellstep runsswamp datastore setup extension @webframp/valkey-datastore --config ...to flip the repo's datastore to Valkey.

2026.10.22.1
Fixed: Existing definitions created against an earlier version were stranded
on upgrade. The model shipped new versions without a corresponding upgrades
chain, so swamp could not migrate a definition's typeVersion and logged a
warning that global arguments would not be migrated. This release backfills the
full upgrade chain through every shipped version and terminates it at the
current version, so stale definitions migrate cleanly. The transform is identity
— no stored global argument value changes.
Upgrade note: No action required. On the next method run, each existing
definition's typeVersion advances to 2026.10.22.1 with its global arguments
preserved.

Added: The manifest now declares license: Apache-2.0 (SPDX). The registry
quality rubric scores a declared license separately from the bundled
LICENSE.md.
Upgrade note: Metadata only. No code, schema, or behavioral changes.
2026.09.18.1
Upgrade note: Normalized npm:zod dependency version to 4.6.5 across the
repo. No behavioral changes in this extension.
Resources
Provision an ElastiCache Serverless (Valkey) cache, security group, and IAM managed policy for @webframp/valkey-datastore, then switch the current repo to use Valkey. After completion the repo is configured. Verify with `swamp datastore status`.

2026.09.15.1
Changed: Bump zod 4.4.3 → 4.6.5
2026.08.28.1
Changed: Normalized the extension license to Apache-2.0 and corrected the copyright holder to "Sean Escriva". Extensions that previously shipped an MIT LICENSE.md are now Apache-2.0, consistent with the repository root and every other extension. No code or behavioral changes.
Upgrade note: License text only. No API, schema, or runtime behavior changed.
2026.08.27.1
Changed: Test suite now builds its method context from the shared
createModelTestContext factory in @systeminit/swamp-testing instead of a
hand-rolled context, wrapping writeResource to preserve the existing assertion
API. No behavioral, schema, or method changes — the published provisioner is
unchanged. The deno.json gains a dev-only @systeminit/swamp-testing
import-map entry and its check task now type-checks the test file.
2026.08.26.3
Fixed: Restored inline npm:zod@4.4.3 import specifiers so the registry
quality scorer can resolve dependencies and score the extension. An earlier
release used a bare "zod" import-map specifier, which published but scored as
unscored.
Changed: Retained explicit compilerOptions.strict in deno.json. No
behavioral or schema changes.

2026.08.26.1
Changed: Normalized deno.json configuration for repo-wide consistency:
added explicit compilerOptions.strict and migrated zod dependency to the
import map (bare "zod" specifier instead of inline npm:zod@4.4.3). No
behavioral changes — runtime resolution is identical.

durationMs: Method execution duration in milliseconds.collectedBy: Extension name that produced the data.fetchedAt: ISO 8601 timestamp when data was fetched (added to resources that previously lacked it).
2026.08.23.1
Fixed: README's Development section referenced a nonexistent
valkey-datastore-bootstrap directory; corrected to
elasticache-datastore-bootstrap.
Changed: Documentation only — no code changes otherwise. Added a
## Troubleshooting section covering the multiple-default-VPC error, the
create-failed/deleting/deleted terminal-state branches in
waitForCacheAvailable, the self-healing ingress-rule check in
ensureSecurityGroup that silently reopens port 6379 to the VPC CIDR on re-run,
and divergent securityGroupId reporting when reusing a cache created with a
different security group.
2026.08.02.1
Fixed: The configure job in @webframp/bootstrap-elasticache-datastore
failed with Invalid expression: No such key: attributes. The workflow queried
data.latest("swamp-valkey-provisioner", "state"), but the provisioner writes
its resource under the instance name "main" (via
writeResource("state", "main", ...)) — data.latest()'s second argument
matches the resource's instance name, not its spec name. The configure job now
queries data.latest("swamp-valkey-provisioner", "main"), which resolves
correctly.
Changed: The run-setup step now passes the provisioner's datastoreConfig
through a DATASTORE_CONFIG environment variable instead of interpolating it
directly into a single-quoted shell string. The prior pattern could allow a
config value containing a single quote to break out of shell quoting.
Upgrade note: No action needed beyond swamp extension pull — the workflow
file is re-pulled with the extension.
2026.07.27.1
Fixed: The fmt task ran deno fmt --check, so deno task fmt verified
formatting instead of applying it and there was no way to format the extension
through its own task. fmt now formats and a new fmt:check verifies, matching
every other extension in the repository.
Fixed: deno fmt no longer inspects CLAUDE.md / AGENTS.md. Those files
are gitignored and never present in CI, but deno fmt does not read .gitignore,
so deno task fmt:check could fail locally on a file CI does not have.
Upgrade note: Tooling and formatting only. No model, method, schema, or behavior change — nothing to do on upgrade.
2026.07.23.1
Added: Initial release of @webframp/elasticache-datastore-bootstrap —
one-shot provisioner for AWS ElastiCache Serverless (Valkey engine) targeting
@webframp/valkey-datastore.
Creates an ElastiCache Serverless cache with TLS, a VPC security group (TCP/6379 from VPC CIDR), and a least-privilege IAM managed policy, then configures the swamp repo datastore via a two-job workflow.
Fixed:
- Subnet IDs from user input are validated per-element against
/^subnet-[a-f0-9]+$/after split, preventing CLI argument injection key_prefixconstrained to max 64 chars and safe characters only ([a-zA-Z0-9_\-:.]) — prevents shell injection via workflow template--policy-documentvalues are redacted from AWS CLI error messages to avoid leaking ARNs and account IDs in logswaitForCacheAvailablethrows immediately when cache returns null (deleted mid-wait) or entersdeleting/deletedterminal stategetDefaultVpcIdthrows if multiple default VPCs found, requiring explicitvpc_id- Idempotency path waits for cache availability when re-running against a cache
