Third packer bug: ami_description had an em-dash (non-ASCII); AWS rejects
non-ASCII in the AMI Description attribute, so packer registered then
DEREGISTERED the first AMI (ami-0545…) on the ModifyImageAttribute error.
Replaced with an ASCII '-'. Rebuilt clean → ami-00080084502093021 (available).
Re-pinned BAKED_OPEN_SWE_AMI_ID.
Packer-build the custom base image and repoint AppService off the AL2023
placeholder onto it.
deploy/ami/open-swe-base.pkr.hcl — fix two bugs that blocked the first real
`packer build` (the config had only ever been `packer validate`'d at T8):
- the file provisioner failed uploading the templates dir ('scp: …: Is a
directory') — a trailing-slash contents-upload needs the dest dir to exist;
added a 'mkdir -p /tmp/open-swe-templates' shell provisioner + dropped the
dest trailing slash.
- the shell provisioner's custom execute_command omitted {{ .Vars }}, so the
environment_vars never reached provision.sh (which runs under set -u and
aborted on CLOUDWATCH_AGENT_DEB_URL). Added {{ .Vars }}.
infra:
- ami-cache.ts: BAKED_OPEN_SWE_AMI_ID = ami-0545363bb147229ff (built 2026-06-26
from open-swe-base-arm64-20260626-201929) + bakedOpenSweArm64() pinning it by
exact id via MachineImage.genericLinux (offline, deterministic). Dropped the
now-dead AL2023 cachedInContext helper + context key; kept the EBS/replacement
discipline docs.
- app-service.ts: machineImage → bakedOpenSweArm64().
- open-swe-stack.ts: output BakedAmiId (was the AL2023 PinnedAmiId guard).
- cdk.context.json → {} (AMI is a static id pin; no context lookups remain).
- README: Baked AMI + EBS-replacement-discipline section.
tsc + cdk synth(dev+prod) + jest(16) clean; template ImageId = the baked AMI.
NOTE: held — do NOT merge until the open-swe-dev secret values are populated
(put-config.sh). The infra CD is live, so merging this to dev auto-deploys
OpenSweDevStack; without secrets the box boots but fetch-config fail-fasts →
unhealthy ALB target on the shared prod ALB. Merge once secrets are set (T14).
PR#2 of the AWS migration. deploy/ami/: Packer template (Ubuntu 24.04 arm64,
uv+py3.12, nginx, awscli v2, CW agent; no swapfile), provisioning-only user-data
(userDataCausesReplacement rationale), systemd unit + nginx + CW templates.
Incorporates T5 /sh-security-review fixes: langgraph binds 127.0.0.1 (not 0.0.0.0);
nginx is the sole ingress proxying only /dashboard/api/ + /webhooks/; ExecStartPre
runs fetch-config as root (+) and passes the env arg; the app runs as the
unprivileged openswe user reading an openswe-owned 0600 .env. packer validate clean.
