# Extension SDK and ext.vm-packer
|
|
|
|
Deliver INTENT near-term outcome #7 (extension SDK sketch) and begin
|
|
`infra/build-machines/` migration via `ext.vm-packer` attach mode.
|
|
|
|
**Predecessor:** SAND-WP-0004 (e2e shim — finished)
|
|
**Follow-on:** SAND-WP-0006 (SaaS extensions + payments), SAND-WP-0007 (snapshots)
|
|
|
|
## Extension SDK
|
|
|
|
```task
|
|
id: SAND-WP-0005-T01
|
|
status: done
|
|
priority: high
|
|
```
|
|
|
|
`SandboxExtension` base class (`src/sandboxer/extensions/base.py`),
|
|
`docs/extension-sdk.md` author guide. `ComposeSSHExtension` refactored to subclass base.
|
|
|
|
## ext.vm-packer attach mode
|
|
|
|
```task
|
|
id: SAND-WP-0005-T02
|
|
status: done
|
|
priority: high
|
|
```
|
|
|
|
`VMPackerExtension` — SSH attach to pre-built VM, workspace under `/build/sbx-<id>/`,
|
|
optional repo rsync, teardown removes workspace only. Registration:
|
|
`extensions/ext.vm-packer.yaml`.
|
|
|
|
## profile.vm-haskell-build
|
|
|
|
```task
|
|
id: SAND-WP-0005-T03
|
|
status: done
|
|
priority: high
|
|
```
|
|
|
|
Profile + runbook for Haskell build VM (build-machines lineage).
|
|
`docs/migration-build-machines.md` maps legacy workflows.
|
|
|
|
## SSH port support
|
|
|
|
```task
|
|
id: SAND-WP-0005-T04
|
|
status: done
|
|
priority: medium
|
|
```
|
|
|
|
`SSHConfig.port` for reverse-tunnel ports (12222). Manager stores `vm_target` /
|
|
`ssh_port` on destroy handle.
|
|
|
|
## Tests
|
|
|
|
```task
|
|
id: SAND-WP-0005-T05
|
|
status: done
|
|
priority: high
|
|
```
|
|
|
|
Unit tests: `test_vm_packer.py`, `test_extension_base.py`, `test_extension_registry.py`.
|
|
|
|
## Deferred
|
|
|
|
```task
|
|
id: SAND-WP-0005-T06
|
|
status: wait
|
|
priority: low
|
|
```
|
|
|
|
Packer build orchestration from `sandboxer create`; the-custodian `make remote-build`
|
|
shim; port-registry automation. |
