mohomo-docker
Minimal Mihomo service with the ACL4SSR Online Full MultiMode routing model. The host exposes only mixed proxy port 7890; SSClash and Mihomo's controller remain loopback-only inside the container.
Quick start
cp .env.example .env
# Replace only SUBSCRIPTION_URL in .env.
docker compose up -d --build
docker compose logs -f ssclash
The subscription endpoint must return a Clash/Mihomo proxy-provider YAML document (proxies:). Use an HTTPS endpoint when its URL contains a credential. Clients connect to either endpoint:
HTTP proxy: http://<server>:7890
SOCKS5 proxy: socks5://<server>:7890
PROXY_BIND and PROXY_PORT are optional deployment overrides. Configure Mihomo proxy authentication before publishing port 7890 outside a trusted network.
Update and secret handling
The bootstrap fetches the subscription once before startup and every hour thereafter. Each candidate is limited to 16 MiB and validated with the packaged Mihomo binary before an atomic replacement and hot reload. A failed reload restores and reloads the previous provider; if that recovery cannot be confirmed, both services stop instead of running with uncertain state.
The subscription URL is read from SUBSCRIPTION_URL, removed from child-process environments, and never printed. The generated configuration contains only a local provider path. Subscription data lives under /dev/shm/mohomo, so neither the image nor the /opt/clash volume stores its URL, response, or node credentials. Container restarts intentionally fetch a fresh subscription instead of persisting credentials.
Do not commit .env; it is ignored by Git. Docker still exposes container environment variables to principals allowed to inspect the container, so restrict Docker daemon access.
ACL4SSR rules
The image packages ACL4SSR provider files from pinned commit 6e27259b8625e360699c014f98f978ee7408c644. The archive checksum is pinned in the Dockerfile. Runtime routing uses only those local files—there is no online rule converter or rule-provider download.
The generated groups and rule order mirror ACL4SSR_Online_Full_MultiMode.ini: automatic selection, fallback, load balancing, regional selectors, service/media splits, ad rejection, China direct routing, GFW routing, and final fallback.
Persistent data
/opt/clash stores only SSClash settings, the packaged Mihomo core, and the non-secret generated configuration. Bootstrap creates missing files, preserves existing regular non-empty files, enforces OPERATING_MODE=server and PROXY_MODE=none, and rejects corrupt or ambiguous persistent state.
Reproducible inputs
The Dockerfile pins:
- SSClash-Go
v6.1.0, verified with its release checksum file; - Mihomo
v1.19.30, verified with repository-pinned SHA-256 values; - ACL4SSR rules by commit and archive SHA-256.
The GitHub Actions workflow builds linux/amd64, runs tests first, publishes only to private GHCR, and attaches SBOM and provenance. Do not make an image containing SSClash-Go public without permission from its copyright holder.
Verification
./scripts/test.sh
./tests/container-smoke.sh
The unit suite checks atomic rollback, URL redaction, server-only listeners, local ACL4SSR providers, and at least 65% bootstrap coverage. The container smoke test builds the image, validates the generated configuration, checks that only port 7890 is published, and verifies that the subscription credential is neither persisted nor logged.
License boundary
Original packaging code is MIT licensed. SSClash-Go, Mihomo, and packaged ACL4SSR rule files retain their upstream licenses; the image includes ACL4SSR's CC BY-SA 4.0 text.
