[BUG] Docker: iii-engine uses in_memory despite file_based config in /app/config.yaml

[jensbe74]

Summary

Fresh clone from GitHub on Linux, using repo docker-compose.yml and iii-config.docker.yaml.
Verified:

• /app/config.yaml is mounted from ./iii-config.docker.yaml
• container sees file_based config with /data/state_store.db and /data/stream_store
• /data volume is mounted correctly
• reproduced on iiidev/iii 0.11.0, 0.11.1, 0.11.2

But engine logs still show:
DO NOT USE IN_MEMORY STORE_METHOD IN PRODUCTION - DATA WILL BE LOST ON SHUTDOWN

Also no /data/.hmac is created and no AGENTMEMORY_SECRET= is logged on first boot.

This suggests the mounted config is parsed but not actually applied by iii-engine in Docker.

Environment

• OS: Ubuntu 22.04.5 LTS (jammy)
• Docker version: 29.5.3
• Docker Compose version: v5.1.4
• agentmemory clone: fresh git clone https://github.com/rohitg00/agentmemory.git
• iiidev/iii versions tested: 0.11.0, 0.11.1, 0.11.2

---

Steps to reproduce

1. git clone https://github.com/rohitg00/agentmemory.git
2. cd agentmemory
3. docker compose up -d
4. docker logs agentmemory-iii-engine-1

---

Expected behavior

• iii-engine should use store_method: file_based from /app/config.yaml
• Data persisted to /data/state_store.db and /data/stream_store
• HMAC secret generated on first boot and logged as AGENTMEMORY_SECRET=...

---

Actual behavior

• Logs show: DO NOT USE IN_MEMORY STORE_METHOD IN PRODUCTION - DATA WILL BE LOST ON SHUTDOWN
• No /data/.hmac created
• No AGENTMEMORY_SECRET= logged

Evidence

docker mount check

docker inspect agentmemory-iii-engine-1 \
  --format '{{range .Mounts}}{{.Type}}{{" "}}{{.Source}}{{" "}}{{.Destination}}{{" "}}{{.Mode}}{{"\n"}}{{end}}'

Output:

volume /var/lib/docker/volumes/agentmemory_iii-data/_data /data rw
bind /root/mcp-hub/agentmemory/iii-config.docker.yaml /app/config.yaml ro

Config in container

docker cp agentmemory-iii-engine-1:/app/config.yaml /tmp/config_in_container.yaml && cat /tmp/config_in_container.yaml

Key part:

- name: iii-state
  config:
    adapter:
      name: kv
      config:
        store_method: file_based
        file_path: /data/state_store.db
- name: iii-stream
  config:
    port: 3112
    host: 0.0.0.0
    adapter:
      name: kv
      config:
        store_method: file_based
        file_path: /data/stream_store

Volume content

sudo ls -la /var/lib/docker/volumes/agentmemory_iii-data/_data/

Output:

total 16
drwxr-xr-x 4 65532 65532 4096 Jun 19 10:25 .
drwx-----x 3 root  root  4096 Jun 19 10:25 ..
drwxr-xr-x 2 65532 65532 4096 Jun 19 10:25 state_store.db
drwxr-xr-x 2 65532 65532 4096 Jun 19 10:25 stream_store

Engine logs

docker logs agentmemory-iii-engine-1 2>&1 | grep -E "(IN_MEMORY|AGENTMEMORY_SECRET)"

Output:

[WARN] iii::builtins::kv DO NOT USE IN_MEMORY STORE_METHOD IN PRODUCTION - DATA WILL BE LOST ON SHUTDOWN
[WARN] iii::builtins::kv DO NOT USE IN_MEMORY STORE_METHOD IN PRODUCTION - DATA WILL BE LOST ON SHUTDOWN

No AGENTMEMORY_SECRET= line.

Note

This is reproducible on multiple iiidev/iii versions (0.11.0, 0.11.1, 0.11.2) with a fresh clone.
