Configuration

EverOS uses a two-file TOML configuration system with environment variable overrides for container deployments.

Quick Start

# 1. Generate config files in the default root (~/.everos/)
everos init

# 2. Edit the config — fill in API keys
$EDITOR ~/.everos/everos.toml

# 3. Start the server
everos server start

Configuration Files

everos.toml — Application Settings

Located at <root>/everos.toml. Controls all application behavior: API bind address, LLM/embedding/rerank provider credentials, SQLite pragmas, search strategy, memorize mode, and clustering tunables.

Generated by everos init from the shipped config/default.toml template. Changes require a server restart.

ome.toml — Strategy Configuration

Located at <root>/ome.toml. Controls the Offline Memory Engine (OME) strategy scheduling: which strategies are enabled, cron expressions, gate thresholds, and retry limits.

Generated by everos init from the shipped config/default_ome.toml template. Changes are hot-reloaded within ~2 seconds — no server restart needed.

Source Priority

Settings are resolved in this order (later wins):

1. config/default.toml — shipped defaults (lowest priority)
2. <root>/everos.toml — user configuration (optional)
3. EVEROS_* environment variables — container/CI overrides
4. Programmatic init args (highest priority; internal use)

Memory Root Resolution

The memory root directory is resolved from three sources (first wins):

Source	Example
--root CLI flag	everos server start --root /data/everos
EVEROS_ROOT env var	export EVEROS_ROOT=/data/everos
Default	~/.everos

All CLI commands that interact with storage accept --root:

everos server start --root /data/everos
everos cascade status --root /data/everos
everos config show --root /data/everos
everos init --root /data/everos

Troubleshooting

Use everos config show to inspect the effective configuration:

everos config show
everos config show --root /data/everos

This prints:

• The resolved root directory
• Which config files were found
• All settings sections with their effective values
• API keys are masked in output

Advanced: Container Deployment

In containerized environments, skip everos init and use environment variables directly:

ENV EVEROS_ROOT=/data/everos
ENV EVEROS_LLM__API_KEY=sk-...
ENV EVEROS_LLM__MODEL=gpt-4o
ENV EVEROS_LLM__BASE_URL=https://api.openai.com/v1
ENV EVEROS_EMBEDDING__MODEL=text-embedding-3-large
ENV EVEROS_EMBEDDING__API_KEY=sk-...
ENV EVEROS_EMBEDDING__BASE_URL=https://api.openai.com/v1
ENV EVEROS_RERANK__MODEL=Qwen/Qwen3-Reranker-4B
ENV EVEROS_RERANK__API_KEY=...
ENV EVEROS_RERANK__BASE_URL=https://api.deepinfra.com/v1/inference
ENV EVEROS_API__HOST=0.0.0.0
ENV EVEROS_API__PORT=8000

Environment variable naming convention:

EVEROS_<SECTION>__<KEY>

• Section and key are uppercased
• Double underscore (__) separates section from key
• Nested sections use additional __ separators

Examples:

TOML	Environment Variable
[llm] api_key = "sk-..."	EVEROS_LLM__API_KEY=sk-...
[sqlite] busy_timeout_ms = 10000	EVEROS_SQLITE__BUSY_TIMEOUT_MS=10000
[memory] timezone = "Asia/Tokyo"	EVEROS_MEMORY__TIMEZONE=Asia/Tokyo
