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.

# Open SWE EC2 user-data — PROVISIONING-ONLY (runs once, at first boot).
|
|
#
|
|
# This is the rationale for `userDataCausesReplacement: true` in CDK: user-data
|
|
# does FIRST-BOOT provisioning, never durable runtime config. Editing it is a
|
|
# deliberate instance replacement. Durable runtime config is fetched fresh on
|
|
# every service start by deploy/seahaven/fetch-config.sh (ExecStartPre).
|
|
#
|
|
# The box holds NO durable state of its own:
|
|
# - secrets/config -> Secrets Manager + SSM, materialized to a tmpfs .env at boot
|
|
# - app artifact -> pulled from S3 (open-swe-<env>-assets) via the instance role
|
|
# - store state -> reseeded by seed_store.sh (ExecStartPost) on every start
|
|
# => there is no RETAIN volume to protect; replacement is tolerated. The EBS
|
|
# discipline (snapshot root + wait state=completed BEFORE any replacing deploy)
|
|
# is the safety net, not durable on-box state. See README "EBS discipline".
|
|
#
|
|
# Tokens (@@...@@) are substituted by CDK when it renders this script into the
|
|
# launch template. region is read from IMDSv2 as a fallback.
