Resolves the explicit "Known follow-up" left by commit 2f8ceeab9 and
the resulting CI failures in tests/docker/test_dashboard.py and
tests/docker/test_s6_profile_gateway_integration.py.
The product gap
---------------
Every hermes runtime operation inside the container runs as the
hermes user (UID 10000) via s6-setuidgid. But s6-supervise — spawned
by s6-svscan running as PID 1 — creates each service's supervise/
and top-level event/ directories with mode 0700 owned by its
effective UID (root). That left every s6-svc / s6-svstat / s6-svwait
call from hermes hitting EACCES on the supervise/control FIFO and
supervise/status — i.e. the entire S6ServiceManager lifecycle
(register, start, stop, unregister) was inert in production.
The 2f8ceeab9 commit message called this out and deferred the fix.
The audit changes that landed alongside it (defaulting docker_exec
to -u hermes) made the integration tests reproduce the bug
deterministically; the fix below resolves it.
The fix: pre-create the supervise/ skeleton hermes-owned
----------------------------------------------------------
Reading s6's source (src/supervision/s6-supervise.c::trymkdir +
control_init), the mkdir and mkfifo calls that build the supervise
tree are EEXIST-safe: if the directory or FIFO is already present,
s6-supervise reuses it and skips the chown/chmod fix-up that would
normally make event/ 03730 root:root. So if we lay the skeleton
down with hermes ownership before triggering s6-svscanctl -a,
s6-supervise inherits our layout and never touches it. The
death_tally / lock / status regular files written later by
s6-supervise (still as root) land mode 0644 — world-readable —
which is all s6-svstat needs.
New module-level helper _seed_supervise_skeleton(svc_dir) in
hermes_cli/service_manager.py lays down:
svc_dir/event/ hermes:hermes 03730
svc_dir/supervise/ hermes:hermes 0755
svc_dir/supervise/event/ hermes:hermes 03730
svc_dir/supervise/control hermes:hermes 0660 (FIFO)
svc_dir/log/event/ hermes:hermes 03730 (if log/ present)
svc_dir/log/supervise/ hermes:hermes 0755
svc_dir/log/supervise/event/ hermes:hermes 03730
svc_dir/log/supervise/control hermes:hermes 0660 (FIFO)
The log/ branch matters because the logger is a second
s6-supervise instance — without it, unregister rmtree races on
the logger's root-owned supervise dir even after the parent
slot's supervise/ is hermes-owned. The helper is idempotent and
swallows PermissionError on chown so it works equally well when
called from root (cont-init.d) or hermes (runtime register).
Wiring
------
1. S6ServiceManager.register_profile_gateway calls
_seed_supervise_skeleton(tmp_dir) just before publishing the
slot via Path.replace. Runtime-registered profile gateways are
set up by hermes.
2. container_boot._register_service does the same in the cont-init.d
reconciliation path so boot-time-restored profile slots inherit
the same layout.
3. New cont-init.d/015-supervise-perms script chowns the supervise/
and event/ trees for STATIC s6-rc services (dashboard,
main-hermes). These are spawned by s6-rc before cont-init.d
gets to run, so the EEXIST-trick doesn't apply; we chown the
already-existing tree instead. s6-supervise keeps using the
same files; it never re-asserts ownership on a running service.
The script skips s6-overlay internal services (s6rc-*,
s6-linux-*) so the supervision tree itself stays root-only.
015- slot is intentional: lex-sorts between 01-hermes-setup
and 02-reconcile-profiles in the container's C-locale, so
the chown finishes before the reconciler walks the scandir.
Unregister teardown reordering
------------------------------
S6ServiceManager.unregister_profile_gateway now fires
s6-svscanctl -an BEFORE rmtree (with a 200ms grace), so
s6-svscan reaps the supervise child and releases its file
handles on supervise/lock + supervise/status before we try to
remove the directory. Previously rmtree raced s6-supervise on a
set of files inside the supervise dir, and even with the parent
supervise/ now hermes-owned, the contained files (death_tally,
lock, status, written by root) could still be in use.
Dashboard down-state redesign
-----------------------------
The original PR #30136 review fix wrote a 'down' marker file
into /run/service/dashboard/ via cont-init.d/03-dashboard-toggle.
That approach was broken in two ways:
(a) /run/service/dashboard is a symlink to a TRANSIENT
/run/s6-rc:s6-rc-init:<tmpdir>/ directory while s6-rc is
mid-transaction; the touch landed in a soon-to-be-discarded
tmp.
(b) Even when written to the final /run/s6-rc/servicedirs/
location, the 'down' file is only consulted by s6-supervise
at slot startup. s6-rc's user-bundle explicitly transitions
'dashboard' to 'up' on every boot, overriding any down
marker.
The right fix is the canonical s6 pattern: when HERMES_DASHBOARD
is unset, the dashboard run script exits 0 and a companion
finish script exits 125. Per s6-supervise(8), exit code 125 from
the finish script is the 'permanent failure, do not restart'
marker — equivalent to s6-svc -O. The slot reports as 'down' to
s6-svstat, matching the reality that no dashboard process is
running. When HERMES_DASHBOARD IS truthy, finish exits 0 and
restart-on-crash semantics apply.
03-dashboard-toggle is removed (its function is now subsumed by
the run/finish pair).
Tests
-----
Adds four unit tests for _seed_supervise_skeleton covering the
produced layout, the log/ subservice case, the skip-when-no-log
case, and idempotency. The live-container verification continues
to live in tests/docker/test_s6_profile_gateway_integration.py and
tests/docker/test_dashboard.py — both now pass against the
rebuilt image.

PR #30136 review item O5: docker/entrypoint.sh is now a thin shim
that forwards to stage2-hook.sh — the real ENTRYPOINT is /init plus
main-wrapper.sh. External scripts that hard-coded entrypoint.sh as
the container's ENTRYPOINT will see the cont-init bootstrap happen
but the CMD will not be exec'd (because stage2-hook only handles
bootstrap; main-wrapper.sh handles the CMD passthrough).
Add a stderr warning explaining the new contract and pointing
callers at the migration path (drop the --entrypoint override).
The shim itself stays in place for one release cycle so the
deprecation isn't a hard break — anyone still invoking it sees
the warning in their logs and has time to migrate.
PR #30136 review caught: three `s6-setuidgid hermes sh -c "..."`
invocations in stage2-hook.sh interpolated $HERMES_HOME into a
nested shell context. Practically low-risk (a malicious HERMES_HOME
already requires container-launch privileges) but the cleaner
pattern is to invoke commands directly so the shell isn't a second
interpreter.
* `mkdir -p` of the data subdirs now runs directly via s6-setuidgid,
one path per arg.
* The .install_method stamp is written via `printf | tee` — also no
shell wrapper.
* The skills_sync invocation uses the venv's python by absolute path
instead of sourcing activate inside a shell. skills_sync.py doesn't
need anything from activate beyond sys.path, which the bin-stub
python already provides.
No behavior change. Just a smaller attack surface and a script
that's easier to read.
PR #30136 review caught a false positive: when HERMES_DASHBOARD was
unset, the dashboard run script did `exec sleep infinity`, so
`s6-svstat /run/service/dashboard` reported the slot as 'up'.
`hermes doctor` and any other s6-svstat-based health check saw the
dashboard as supervised-running even though no dashboard process
existed.
Add cont-init.d/03-dashboard-toggle: writes a `down` marker file
into `/run/service/dashboard/` when HERMES_DASHBOARD is falsy,
removes any leftover marker when it's truthy. s6-supervise honors
`down` by not starting the service, so s6-svstat reports 'down' —
matching reality.
The run script's HERMES_DASHBOARD case-statement stays in place as
a belt-and-suspenders guard, so the two layers can never disagree.
Two new integration tests lock the behavior: slot reports down
when unset; slot reports up when set to 1.
PR #30136 review surfaced two issues, both rooted in the same audit gap:
docker integration tests were running as root, not the unprivileged
`hermes` user (UID 10000) that the runtime actually uses via
`s6-setuidgid hermes`. Anything that probed PID-1 state or wrote to
the s6 control surface worked as root in the tests but was inert in
production.
Fixes:
1. `_s6_running()` previously called `Path("/proc/1/exe").resolve()`,
which is root-only readable. For UID 10000 the symlink yields
PermissionError, `resolve()` silently returns the unresolved path,
and `exe.name == "exe"` — so detection always returned False, the
service-manager runtime-registration path was inert, and every
`hermes profile create` / `hermes -p X gateway start` silently
skipped the s6 hook. Replace with `/proc/1/comm` (world-readable)
+ `/run/s6/basedir` (s6-overlay-specific) — both required, fail
closed.
2. `02-reconcile-profiles` now also chowns `/run/service/.s6-svscan/`
{control,lock} to hermes so `s6-svscanctl -a/-an` works without
root. Previously the directory chown stopped at `/run/service`
and the FIFO inside stayed root-owned, so `register_profile_gateway`
from hermes failed at the rescan-trigger step with EACCES — the
wrapper in profiles.py caught the exception and printed a swallowed
warning, so profile creation appeared to succeed while the slot
was rolled back.
Audit changes to flush this class of bug next time:
- Add `docker_exec` / `docker_exec_sh` helpers to `tests/docker/conftest.py`
that default to `-u hermes`. The module docstring explains why and
flags `user="root"` as opt-in only for tests that explicitly need
root (none currently do).
- Refactor every `docker exec` call in tests/docker/ through the new
helpers (test_dashboard.py, test_zombie_reaping.py, test_profile_gateway.py,
test_container_restart.py, test_s6_profile_gateway_integration.py).
- Add 5 unit tests covering `_s6_running` under various probe states
(both signals present; comm wrong; basedir missing; PermissionError
on /proc/1/comm; missing /proc — non-Linux). The PermissionError
test is the explicit regression guard for the original bug.
Known follow-up: the per-service `supervise/control` FIFO inside each
`/run/service/gateway-<profile>/supervise/` is created root-owned by
s6-supervise (which runs as root because s6-svscan is PID 1). `s6-svc
-u/-d/-t` from the hermes user will get EACCES on those. The audit
under `-u hermes` will reveal this in lifecycle tests — surfacing the
issue cleanly so it can be fixed in a focused follow-up (likely via a
small SUID helper or a polling chown loop in cont-init.d). The
detection + svscanctl fixes here are independent and complete on
their own.
The s6-overlay migration replaced every runtime use of gosu with
s6-setuidgid (in stage2-hook.sh, main-wrapper.sh, per-service run
scripts, and cont-init.d hooks), but the gosu binary itself was still
being copied into the image from tianon/gosu, and several comments
across the repo still pointed to it.
Image changes:
- Drop the FROM tianon/gosu:1.19-trixie AS gosu_source stage
- Drop the COPY --from=gosu_source /gosu /usr/local/bin/ layer
- Net: one fewer base-image pull, ~12-15 MB layer eliminated
Documentation/comment refresh (no behavior change):
- Dockerfile: update root-user rationale comment + cont-init.d comment
- docker/main-wrapper.sh: drop "pre-s6 contract (gosu drop)" reference
- docker-compose.yml: update UID/GID remap comment
- .hadolint.yaml: update DL3002 ignore rationale
- website/docs/user-guide/docker.md: privilege-drop helper is s6-setuidgid now
- hermes_cli/config.py: docker_run_as_host_user docstring
tools/environments/docker.py runs *arbitrary user images* via the
terminal backend, not the bundled Hermes image. It still needs SETUID/
SETGID caps so user images that use gosu/su/s6-setuidgid all work.
Renamed the cap-list constant _GOSU_CAP_ARGS → _PRIVDROP_CAP_ARGS and
updated comments to list s6-setuidgid alongside the others as examples.
The matching test (test_security_args_include_setuid_setgid_for_gosu_drop
→ test_security_args_include_setuid_setgid_for_privdrop) was renamed
and its docstring updated; behavior is unchanged.
Verification:
- hadolint clean against .hadolint.yaml
- shellcheck clean against all docker/ shell scripts
- Image rebuilt successfully (sha 1a090924ccea)
- Docker harness: 19 passed in 41.87s (every Phase 0 test + Phase 4
per-profile-gateway lifecycle + container-restart reconciliation)
- tests/tools/test_docker_environment.py: 23 passed (rename did not
break test discovery; pre-existing unrelated mock warning)
The plan document (docs/plans/2026-05-07-s6-overlay-dynamic-subagent-gateways.md)
intentionally retains its historical references to gosu — it describes
the pre-s6 entrypoint as background for understanding the migration.
Phase 4 of the s6-overlay supervision plan. Activates the Phase 3
S6ServiceManager by hooking it into the profile lifecycle and the
`hermes gateway start/stop/restart` dispatcher, and adds a cont-
init.d-time reconciliation pass that survives `docker restart`.
Task 4.0 — container-boot reconciliation:
/run/service/ is tmpfs, so every `docker restart` wipes every
per-profile gateway slot. /etc/cont-init.d/02-reconcile-profiles
invokes hermes_cli.container_boot.reconcile_profile_gateways() on
every boot, which walks $HERMES_HOME/profiles/<name>/, reads each
gateway_state.json, recreates the s6 service slot, and auto-starts
only those whose last state was 'running'. Other states
(stopped, starting, startup_failed, missing) register the slot
in the down state — avoiding crash-loops across restarts for a
gateway that was broken last boot. Per-profile outcome is recorded
to $HERMES_HOME/logs/container-boot.log.
Implementation: hermes_cli/container_boot.py + 12 unit tests.
Profile-marker is SOUL.md, not config.yaml, because `hermes profile
create` only seeds SOUL.md by default (config.yaml comes from
`hermes setup`).
Task 4.1 / 4.2 — profile create/delete hooks:
hermes_cli/profiles.py::create_profile now calls
_maybe_register_gateway_service(<canon>) at the end, which routes
through ServiceManager.register_profile_gateway when running on s6
and no-ops on host backends. delete_profile mirrors with
_maybe_unregister_gateway_service. _allocate_gateway_port produces
a deterministic SHA-256-derived port in [9200, 9800).
Task 4.3 — gateway dispatch + remove rejection arms:
_dispatch_via_service_manager_if_s6(action) intercepts
start/stop/restart at the top of each subcommand and routes them
through S6ServiceManager.{start,stop,restart}. The pre-Phase-4
`elif is_container():` rejection arms are kept as fallback for
pre-s6 containers / unsupported runtimes, but only ever fire when
detect_service_manager() != 's6'. install/uninstall under s6
print informational guidance pointing users at profile create/delete.
Removed the two xfail(strict=True) markers from
tests/docker/test_profile_gateway.py — both tests now pass strictly.
Task 4.4 — status reporting:
get_gateway_runtime_snapshot() reports
Manager: 's6 (container supervisor)' inside an s6 container instead
of 'docker (foreground)'.
Plan-vs-reality drift fixed in this commit:
- Plan's S6ServiceManager._render_run_script used
`gateway start --foreground --port {port}` — invented args; the
real CLI is `gateway run`. Switched accordingly. port arg
retained for API parity but now documented as 'currently ignored'.
- Plan's reconciler keyed on config.yaml; switched to SOUL.md
(config.yaml is created by hermes setup, not by hermes profile
create, so the original gate caught nothing).
- The plan's _dispatch helper used _profile_arg() which returns
'--profile <name>' (i.e. with the flag prefix). Switched to
_profile_suffix() which returns the bare name.
- Architecture B's docker exec doesn't get /command on PATH or
the venv on PATH; Dockerfile's runtime PATH now includes
/opt/hermes/.venv/bin so 'docker exec <c> hermes ...' works
without sourcing the venv.
- stage2-hook now chowns $HERMES_HOME/profiles to hermes on every
boot, not just on the UID-remap path. Without this, files created
by docker-exec-as-root accumulate and the next reconciler run
fails with PermissionError reading SOUL.md.
Test harness:
19 passed, 0 xfailed (the two pre-Phase-4 xfail targets flip to
passing). 78 unit tests across service_manager + container_boot +
profiles_s6_hooks + gateway_s6_dispatch. Hadolint + shellcheck
pass cleanly.

BREAKING CHANGE: the container ENTRYPOINT is now /init (s6-overlay)
instead of /usr/bin/tini. Main hermes runs as the container CMD with
TTY inherited (preserving --tui), dashboard runs as a supervised s6-rc
service (HERMES_DASHBOARD=1 starts it; crashes auto-restart), and the
ground is laid for per-profile gateway supervision (Phase 3+4).
All five pre-s6 docker run invocation patterns continue to work
identically — verified by the Phase 0 docker harness:
docker run <image> → `hermes` with no args
docker run <image> chat -q "..." → `hermes chat -q ...` passthrough
docker run <image> sleep infinity → `sleep infinity` direct
docker run <image> bash → interactive bash
docker run -it <image> --tui → interactive Ink TUI
Phase 2 harness result: 12 passed, 2 xfailed (Phase 4 target). Hadolint
+ shellcheck pass cleanly.
Architecture pivot from plan v3 (documented in main-hermes/run header):
the plan called for main hermes to be an s6-supervised service, but
two real s6-overlay v3 mechanics blocked that — cont-init.d scripts
receive no arguments (CMD args are not visible to stage2-hook), and
`/run/s6/basedir/bin/halt` after writing the exit code did not
propagate the desired exit code (container exits 143). We use the
s6-overlay-native CMD pattern instead: main-wrapper.sh is the
container's main program (ENTRYPOINT prepends it so leading-dash
args like --version aren't intercepted by /init), exec's the final
program with stdin/stdout/stderr inherited, and the program's exit
code becomes the container exit code. main-hermes is now a no-op
`sleep infinity` slot kept for future supervised-gateway-container
modes. This trades "supervised restart of main hermes" for arg-
parity with the pre-s6 contract — main hermes was already unsupervised
under tini, so we lose nothing functional. Dashboard supervision is
the only new guarantee added by this phase.

* feat(config): add install-method stamping + Docker detection
Dockerfile stamps "docker", install.sh stamps "git", and cmd_postinstall
stamps "pip" into ~/.hermes/.install_method. detect_install_method() reads
the stamp first, then falls back to managed-system / container / .git
heuristics. Adds Docker upgrade guidance.
Tracking: #27826
* fix(stamp): move Docker stamp to entrypoint, install.sh stamp after print_success
The Dockerfile stamp was overwritten by the VOLUME overlay at container
start. Moving it to entrypoint.sh ensures it persists. The install.sh
stamp now writes after print_success so it only lands on full success.
The Dockerfile permissions section made /opt/hermes/.venv readable but not
writable by the hermes runtime user. Since the 2026-05-12 policy change
moved messaging packages (discord.py, telegram, slack, etc.) out of [all]
and into lazy_deps.py, the Docker image no longer ships with them
pre-installed. At first gateway boot, lazy_deps.ensure() tries to
`uv pip install` them into the venv but fails with EACCES because
site-packages is root-owned.
The result: every messaging platform adapter silently fails to load inside
Docker containers, producing only a cryptic "discord.py not installed"
warning despite the gateway being correctly configured.
Two-part fix:
1. Dockerfile: add /opt/hermes/.venv to the existing chown -R hermes:hermes
line so the default (UID 10000) case works out of the box.
2. docker/entrypoint.sh: extend the needs_chown block to also re-chown the
.venv when HERMES_UID is remapped. Without this, the build-time chown
becomes stale when someone uses the documented HERMES_UID override in
docker-compose.yml.

Lets orchestrators (e.g. an account-management service provisioning a
Hermes VPS) seed an OAuth refresh credential non-interactively instead of
walking the user through `hermes setup` + the device-flow login dance.
Matches the existing first-boot-only pattern used for .env, config.yaml,
and SOUL.md.
If HERMES_AUTH_JSON_BOOTSTRAP is set and $HERMES_HOME/auth.json doesn't
already exist, write the env var's contents to auth.json with mode 600.
The `[ ! -f ... ]` guard is critical: it ensures that on container
restart the rotated refresh token Hermes wrote back to the persistent
volume is never clobbered by the now-stale value the orchestrator
originally seeded.
Generic name (not Nous-specific) so the feature is reusable by any future
orchestrator.
Adds an optional dashboard side-process to the container entrypoint,
toggled by `HERMES_DASHBOARD=1` (also accepts `true` / `yes`). When set,
the entrypoint backgrounds `hermes dashboard` before `exec`-ing the main
command so the user's chosen foreground process (gateway, chat, `sleep
infinity`, …) remains PID-of-interest for the container runtime.
docker run -d \
-v ~/.hermes:/opt/data \
-p 8642:8642 -p 9119:9119 \
-e HERMES_DASHBOARD=1 \
nousresearch/hermes-agent gateway run
Defaults chosen for the container case:
- Host: 0.0.0.0 (reachable through published port; can override to
127.0.0.1 via HERMES_DASHBOARD_HOST for sidecar/reverse-proxy setups)
- Port: 9119 (matches `hermes dashboard`)
- Auto-adds `--insecure` when binding to non-localhost, matching the
dashboard's own safety gate for exposing API keys
- HERMES_DASHBOARD_TUI is read by `hermes dashboard` directly — no
entrypoint plumbing needed
Dashboard output is prefixed with `[dashboard]` via `stdbuf`+`sed -u` so
it's easy to separate from gateway logs in `docker logs`. No supervision:
if the dashboard crashes it stays down until the container restarts
(documented in the `:::note` panel).
Other changes bundled in:
- Deprecate GATEWAY_HEALTH_URL / GATEWAY_HEALTH_TIMEOUT env vars in
hermes_cli/web_server.py with a DEPRECATED block comment and a
`.. deprecated::` note on _probe_gateway_health. The feature still
works for this release; it'll be removed alongside the move to a
first-class dashboard config key.
- Rewrite the "Running the dashboard" doc section around the new
single-container pattern. Drops the previously-documented
dashboard-as-its-own-container setup — that pattern relied on the
deprecated env vars for cross-container gateway-liveness detection,
and without them the dashboard would permanently report the gateway
as "not running".
- Collapse the two-service Compose example (gateway + dashboard
container) into a single service with HERMES_DASHBOARD=1. Removes
the now-unnecessary bridge network and `depends_on`.
- Drop the ":::warning" caveat about "Running a dashboard container
alongside the gateway is safe" — that case no longer exists.
The chown/chmod block on config.yaml was added in b24d239ce to keep the
file readable by the hermes runtime user, but it sat in the post-gosu
'running as hermes' section of the entrypoint. That meant:
1. Default `docker run <image>` — container starts as root, entrypoint
drops to hermes via gosu, then non-root hermes tries to chown the
file to hermes. Works by coincidence because the file was just
created by root during volume setup and gosu target == target owner.
2. `docker run -u $(id -u):$(id -g) <image>` (#15865) — container
starts as the caller's UID. The root block is skipped entirely, we
land in the hermes section as some arbitrary non-root user, and
chown to 'hermes' fails with 'Operation not permitted'. Script
aborts under `set -e`.
Move the chown/chmod into the root block (before the gosu exec) where
it actually has privilege, and guard with `2>/dev/null || true` so
rootless Podman (where even in-container root lacks host-side chown
rights) doesn't abort either.
Closes#15865
- Remove 'USER hermes' from Dockerfile so entrypoint runs as root and can
usermod/groupmod before gosu drop. Add chmod -R a+rX /opt/hermes so any
remapped UID can read the install directory.
- Fix entrypoint chown logic: always chown -R when HERMES_UID is remapped
from default 10000, not just when top-level dir ownership mismatches.
- Add docker-compose.yml with gateway + dashboard services.
- Add .hermes to .gitignore.
Commit 8254b820 ("--init for zombie reaping + sleep infinity for
idle-based lifetime") made the Docker terminal backend launch
sandbox containers with `sleep infinity` as the command, so the
lifetime is controlled by an external idle reaper instead of a
fixed timeout.
But `docker/entrypoint.sh` unconditionally wraps its args with
`hermes`:
exec hermes "$@"
Result: `hermes sleep infinity` → argparse rejects `sleep` as a
subcommand and the container exits immediately with code 2:
hermes: error: argument command: invalid choice: 'sleep'
(choose from chat, model, gateway, setup, ...)
Every sandbox container launched by the docker backend dies at
startup, breaking terminal/file tool execution end-to-end.
Fix: dispatch at the tail of the entrypoint. If the first arg is
an executable on PATH (sleep, bash, sh, etc.) run it raw; otherwise
preserve the legacy `hermes <subcommand>` wrapping behavior. Both
invocation styles below keep working:
docker run <image> -> hermes (interactive)
docker run <image> chat -q "hi" -> hermes chat -q "hi"
docker run <image> sleep infinity -> sleep infinity
docker run <image> bash -> bash

- Keep procps for container debugging
Based on work by m0n5t3r in PR #5811. Stripped to hardening-only
changes (non-root, virtualenv, slim base); matrix deps, fonts, xvfb,
and entrypoint playwright download deferred to follow-up.
The profile system expects these directories but they weren't
being created on container startup. Adds them to the mkdir list
alongside the existing dirs.

Isolate system tool configs (git, ssh, gh, npm) per profile by injecting
a per-profile HOME into subprocess environments only. The Python
process's own os.environ['HOME'] and Path.home() are never modified,
preserving all existing profile infrastructure.
Activation is directory-based: when {HERMES_HOME}/home/ exists on disk,
subprocesses see it as HOME. The directory is created automatically for:
- Docker: entrypoint.sh bootstraps it inside the persistent volume
- Named profiles: added to _PROFILE_DIRS in profiles.py
Injection points (all three subprocess env builders):
- tools/environments/local.py _make_run_env() — foreground terminal
- tools/environments/local.py _sanitize_subprocess_env() — background procs
- tools/code_execution_tool.py child_env — execute_code sandbox
Single source of truth: hermes_constants.get_subprocess_home()
Closes#4426
Adds a complete Docker packaging for Hermes Agent:
- Dockerfile based on debian:13.4 with all deps
- Entrypoint that bootstraps .env, config.yaml, SOUL.md on first run
- CI workflow to build, test, and push to DockerHub
- Documentation for interactive, gateway, and upgrade workflows
Closes#850, #913.
Changes vs original PR:
- Removed pre-created legacy cache/platform dirs from entrypoint
(image_cache, audio_cache, pairing, whatsapp/session) — these are
now created on demand by the application using the consolidated
layout from get_hermes_dir()
- Moved docs from docs/docker.md to website/docs/user-guide/docker.md
and added to Docusaurus sidebar
