Create operational runbook covering health checks, start/stop/restart (MCP and Docker Compose), backup/restore, garbage collection, and incident procedures for database corruption, TLS expiry, MCIAS outage, disk full, and push/pull failures. Includes MCP service definition reference for the two-component deployment (mcr-api + mcr-web). Rewrite README from 2-line stub to full project overview with quick-start instructions, binary descriptions, port tables, and links to ARCHITECTURE.md and RUNBOOK.md per engineering standards.

# MCR
|
|
|
|
Metacircular Container Registry -- an OCI Distribution Spec-compliant
|
|
container registry for the Metacircular platform. MCR stores and serves
|
|
container images with authentication delegated to MCIAS and a local
|
|
policy engine for fine-grained access control. Metadata is stored in
|
|
SQLite; blobs are stored as content-addressed files on the filesystem.
|
|
|
|
## Quick Start
|
|
|
|
Build the binaries:
|
|
|
|
```bash
|
|
make all
|
|
```
|
|
|
|
This produces three binaries:
|
|
|
|
| Binary | Purpose |
|
|
|--------|---------|
|
|
| `mcrsrv` | Registry server (OCI + admin REST + gRPC) |
|
|
| `mcr-web` | Web UI (htmx, communicates with mcrsrv via gRPC) |
|
|
| `mcrctl` | Admin CLI |
|
|
|
|
Copy and edit the example configuration:
|
|
|
|
```bash
|
|
cp deploy/examples/mcr.toml /srv/mcr/mcr.toml
|
|
# Edit TLS paths, database path, storage paths, MCIAS URL
|
|
```
|
|
|
|
Run the server:
|
|
|
|
```bash
|
|
./mcrsrv server --config /srv/mcr/mcr.toml
|
|
```
|
|
|
|
The server starts two listeners:
|
|
|
|
| Port | Protocol | Purpose |
|
|
|------|----------|---------|
|
|
| 8443 | TCP | HTTPS -- OCI Distribution endpoints + admin REST API |
|
|
| 9443 | TCP | gRPC admin API (TLS, MCIAS auth) |
|
|
|
|
Run the web UI:
|
|
|
|
```bash
|
|
./mcr-web server --config /srv/mcr/mcr.toml
|
|
```
|
|
|
|
| Port | Protocol | Purpose |
|
|
|------|----------|---------|
|
|
| 8080 | TCP | HTTP -- web UI (repository browsing, policy management) |
|
|
