The challenge is resolved from the instancer store record, and the solver runs with HOST / PORT / URL derived from the instance's host-port mapping (instead of the deploy block) plus INSTANCE_ID / TEAM_ID stamped. The instance's per-team flag is accepted alongside the manifest flags, so dynamic-flag spawns verify correctly. The instance-to-target resolution is split into a pure helper behind a narrow interface so it's unit-testable without docker or a store on disk. --- README.md | 2 +- cmd/solve.go | 68 +++++++++++++++++++++++-- cmd/solve_test.go | 76 ++++++++++++++++++++++++++++ docs/BACKLOG.md | 1 - internal/solve/solve.go | 98 +++++++++++++++++++++++++++++++++--- internal/solve/solve_test.go | 98 ++++++++++++++++++++++++++++++++++++ 6 files changed, 330 insertions(+), 13 deletions(-) create mode 100644 cmd/solve_test.go diff --git a/README.md b/README.md index 4361991..9a15390 100644 --- a/README.md +++ b/README.md @@ -87,7 +87,7 @@ Requires Go 1.23+, GNU make.

The diff now also compares content: the local file's SHA1 against the sha1sum CTFd reports for each file. A same-named pair whose hashes differ is re-uploaded (the local copy is added, then the stale remote copy is deleted). SHA1 rather than sha256 because that is the digest CTFd records and exposes; comparing against any other algorithm would never match. When either side's hash is unavailable (older CTFd builds omit sha1sum, or a local read fails) the file falls back to the previous basename-only behavior, so a sync never churns on missing data. --- README.md | 2 +- docs/BACKLOG.md | 1 - internal/platform/ctfd/client.go | 5 ++- internal/platform/ctfd/sync.go | 62 +++++++++++++++++++++++----- internal/platform/ctfd/sync_test.go | 64 +++++++++++++++++++++++++++++ 5 files changed, 120 insertions(+), 14 deletions(-) diff --git a/README.md b/README.md index 4361991..a24e206 100644 --- a/README.md +++ b/README.md @@ -112,7 +112,7 @@ Requires Go 1.23+, GNU make.

Now the translate/tag/orphan-cleanup logic is gated behind hasRegistry (cfg.Registry != nil && cfg.Registry.URL != ""). Simple-profile deploys use the original docker-compose.yml unchanged. Also fixes down command to fallback to docker-compose.yml when the generated docker-compose.mctf.yml does not exist. Refactors loadPlanAndRunner to return *config.Config so down can check registry presence without reloading config. --- cmd/deploy.go | 120 +++++++++++++++++++++++++++----------------------- 1 file

Not yet released to `main`. + +### Features + +- **`feat(instancer)`: per-team dynamic flags** — the instancer now mints a unique flag per spawn when `flags[].dynamic: true` is set on a challenge. `SpawnOptions.FlagOverride` lets callers pass a pre-generated value; `Instance.Flag` persists it in the store. Schema extended with `flags[].dynamic` and `flags[].generator` (reserved). Validation rules added: `A010` (dynamic flag on non-instanced challenge) and `A011` (static flag + `dynamic: true` conflict). + +- **`feat(generate)`: Prometheus scrape config generator** — `mctf generate` now emits `monitoring/prometheus.yml` with one scrape job per instanced challenge (sorted, deterministic). Only emitted when the event has at least one instanced challenge or `monitoring:` is explicitly set in `mctf.config.yml`. Previously the field was reserved and unconditionally written; it is now fully conditional via `shouldEmitPrometheus()`. + +- **`feat(doctor)`: advanced host checks D040–D042** — `mctf doctor` gained three new checks: DNS resolution (`D040`), free disk space (`D041`, warns < 15 GB / fails < 5 GB), and Docker storage driver (`D042`, warns on `vfs`). + +- **`feat(validate)`: SEC004 capability allowlist** — `mctf validate` now enforces `SEC004`: `cap_add` lists containing privileged capabilities (`SYS_ADMIN`, `NET_ADMIN`, `SYS_PTRACE`, `SYS_MODULE`) are hard-failed unless `deploy.security_opts.allow_caps` explicitly allowlists them. + +- **`feat(solve)`: `--against-instance` flag** — `mctf solve` can now be pointed at a live per-team instance. The solver script receives the instance's host-port mapping and the per-team flag is accepted in addition to the manifest's static flag. + +- **`feat(platform)`: CTFd asset content-hash re-upload** — `mctf platform sync` now re-uploads CTFd assets when their content hash changes, not just when the filename changes. Prevents stale handout files on CTFd. + +- **`feat(deploy)`: GitOps state sync + rollback** — `mctf deploy` gained a rollback system.

Sep 17 00:00:00 2001 From: ademboukabes Date: Fri, 2 Oct 2026 23:37:36 +0100 Subject: [PATCH 48/70] fix(k8s): address blockers and production readiness review - Fix systematic mtcf -> mctf naming across kubernetes package and tests - Use filepath.Join for challenge path in KubeUnit for cross-platform compatibility - Implement Burstable QoS (requests declared, limits 2x CPU) while keeping memory limit=request for OOM safety - Support fixed NodePort on TCP challenges (deploy.port) so participants have stable endpoints - Add InitialDelaySeconds to liveness and readiness probes to prevent startup CrashLoopBackOff - Target exact resource names in kubectl delete instead of broad label selectors - Format Go doc comments according to idiomatic Go style - Add comprehensive test coverage for Burstable QoS, fixed NodePort, and probe initial delays --- internal/kubernetes/builder.go | 56 +++++++++++++++++++++------- internal/kubernetes/e2e_test.go | 26 ++++++-------

internal/kubernetes/plan & runner: deterministic NodePort mapping (30000-32767 range), duplicate NodePort detection, idempotent namespace auto-creation, and synchronous rollout verification via kubectl rollout status. - internal/validate: implement validation rules K001 (NodePort range/mapping), K002 (RFC 1123 label naming), and K003 (cross-challenge NodePort collisions). - docs & schema: update specification changelog, validation guide, and mctf-config schema with node_port_base. --- cmd/deploy.go | 104 +++++++++++++----- cmd/deploy_mode_test.go | 102 +++++++++++++++++ docs/spec/CHANGELOG.md | 6 + docs/spec/validation.md | 14 +++ internal/config/config.go | 5 + internal/kubernetes/builder.go | 92 ++++++++++++++-- internal/kubernetes/e2e_test.go | 2 +- internal/kubernetes/manifest_test.go | 95 ++++++++++++++++ internal/kubernetes/nodeport_test.go | 134 +++++++++++++++++++++++ internal/kubernetes/plan.go | 34 +++++- internal/kubernetes/runner.go | 67 +++++++++++- internal/kubernetes/types.go | 64 ++++++++--- internal/schemas/mctf-config.schema.json | 8 +- internal/validate/checks.go | 1 + internal/validate/k8s.go | 81 ++++++++++++++ internal/validate/k8s_checks.go | 52 +++++++++ internal/validate/k8s_checks_test.go | 116 ++++++++++++++++++++ internal/validate/k8s_test.go | 103 +++++++++++++++++ schema/mctf-config.schema.json | 8 +- 19 files changed, 1020 insertions(+), 68 deletions(-) create mode 100644 cmd/deploy_mode_test.go create mode 100644 internal/kubernetes/nodeport_test.go create mode 100644 internal/validate/k8s.go create mode 100644 internal/validate/k8s_checks.go create mode 100644 internal/validate/k8s_checks_test.go create mode 100644 internal/validate/k8s_test.go diff --git a/cmd/deploy.go b/cmd/deploy.go index 2a6af77..69f2d06 100644 --- a/cmd/deploy.go +++ b/cmd/deploy.go @@ -48,8 +48,21 @@ var deployCmd = &cobra.Command{ return err } + mode, err := deployMode(cfg, flagDeployMode) + if err != nil { + return err + } + // Kubernetes mode: delegate entirely to the K8s planner. -

Used by CI tooling. diff --git a/internal/deploy/deploy.go b/internal/deploy/deploy.go index 56558b1..61a9f59 100644 --- a/internal/deploy/deploy.go +++ b/internal/deploy/deploy.go @@ -72,7 +72,7 @@ func Plan(cfg *config.Config, eventRoot string, challs []*challenge.Challenge, o ProjectName: ProjectName(cfg, c), Cwd: cwd, ComposeFile: filepath.Join(cwd, "docker-compose.yml"), - Env: envForUnit(c, opts.ImageTag), + Env: envForUnit(c), ImageTag: opts.ImageTag, } out = append(out, u) @@ -94,25 +94,20 @@ func ProjectName(cfg *config.Config, c *challenge.Challenge) string { // challenges with internal_port set, it stamps PORT_ with // the manifest's port so the compose's ${PORT_N:-N} convention picks // the right host port. -func envForUnit(c *challenge.Challenge, imageTag string) map[string]string { - env := make(map[string]string) - if imageTag != "" { - env["IMAGE_TAG"] = imageTag - } +// +// The pinned image tag is written literally into docker-compose.mctf.yml +// by TranslateCompose, so it is not passed through the environment. +func envForUnit(c *challenge.Challenge) map[string]string { if c.Manifest.Deploy == nil { - if len(env) == 0 { - return nil - } - return env + return nil } d := c.Manifest.Deploy if d.InternalPort != nil && d.Port != nil { - env[fmt.Sprintf("PORT_%d", *d.InternalPort)] = fmt.Sprintf("%d", *d.Port) - } - if len(env) == 0 { - return nil + return map[string]string{ + fmt.Sprintf("PORT_%d", *d.InternalPort): fmt.Sprintf("%d", *d.Port), + } } - return env + return nil } // UpArgs renders the docker CLI args for `docker compose up -d`. diff --git a/internal/deploy/deploy_test.go b/internal/deploy/deploy_test.go index 835710b..5955588 100644 --- a/internal/deploy/deploy_test.go +++ b/internal/deploy/deploy_test.go @@ -258,3 +258,31 @@ func TestApplyUp_StopsOnError(t *testing.T) { t.Errorf("expected only 'a' to have run, got %v", r.upOrder) } } + +func TestEnvForUnit(t *testing.T) { + root := t.TempDir() + + // Service challenge with port mapping: PORT_ is stamped, and + // the pinned image tag is NOT carried through the env (it is written + // literally into the compose by TranslateCompose). + svc := newChall(t, root, "web", "svc", challenge.ArchetypeService, true, 8080, 80) + env := envForUnit(svc) + if got := env["PORT_80"]; got != "8080" { + t.Errorf("PORT_80 = %q, want 8080", got) + } + if _, ok := env["IMAGE_TAG"]; ok { + t.Error("env must not carry IMAGE_TAG — the tag is pinned literally in the compose") + } + + // Service challenge without an explicit port: no env at all. + bare := newChall(t, root, "web", "bare", challenge.ArchetypeService, true, 0, 0) + if env := envForUnit(bare); env != nil { + t.Errorf("expected nil env for portless service, got %v", env) + } + + // Static challenge (no deploy block): no env. + static := newChall(t, root, "misc", "stat", challenge.ArchetypeStatic, false, 0, 0) + if env := envForUnit(static); env != nil { + t.Errorf("expected nil env for static challenge, got %v", env) + } +} diff --git a/internal/deploy/translate.go b/internal/deploy/translate.go index 6e69faa..94197bf 100644 --- a/internal/deploy/translate.go +++ b/internal/deploy/translate.go @@ -11,9 +11,19 @@ import ( // TranslateCompose reads the docker-compose.yml file from the unit's // Cwd, removes 'build' sections, and injects the registry-pinned image -// using the ${IMAGE_TAG} environment variable.

Not yet released to `m - **`feat(generate)`: Prometheus scrape config generator** — `mctf generate` now emits `monitoring/prometheus.yml` with one scrape job per instanced challenge (sorted, deterministic). Only emitted when the event has at least one instanced challenge or `monitoring:` is explicitly set in `mctf.config.yml`. Previously the field was reserved and unconditionally written; it is now fully conditional via `shouldEmitPrometheus()`. +- **`feat(instance)`: remote instancer control plane** — when `instancer.url` is set in `mctf.config.yml`, `mctf instance list` and `mctf instance destroy` drive the dedicated [MCTF Instancer](https://github.com/MicroClub-USTHB/mctf-instancer) over its admin API (`X-Admin-Key` from `MCTF_INSTANCER_ADMIN_KEY`) instead of the local on-disk store. New `internal/instancer.APIClient` (`List` / `Destroy`). The built-in `mctf instancer` daemon is now documented as deprecated — kept for offline local dev, removed later. Fully backward compatible: with no `instancer.url`, the local store/daemon path is unchanged. + - **`feat(monitoring)`: `mctf monitoring up` / `down`** — brings up the observability stack (Prometheus + Grafana + cAdvisor) via docker compose. `up` renders `monitoring/stack/` from the current config and challenge set — a full Prometheus config (self + cAdvisor + one job per instanced challenge, targeting `host.docker.internal` so targets are reachable from inside the container), a docker-compose with pinned images, and Grafana auto-provisioned with the Prometheus datasource and a container-overview dashboard. `--dry-run` prints the plan and compose command without touching disk; `down --volumes` also drops the data volumes. Ports, Grafana password, and retention are tunable under the `monitoring:` block in `mctf.config.yml`. See `docs/spec/monitoring.md`. - **`feat(doctor)`: advanced host checks D040–D042** — `mctf doctor` gained three new checks: DNS resolution (`D040`), free disk space (`D041`, warns < 15 GB / fails < 5 GB), and Docker storage driver (`D042`, warns on `vfs`).

Schema extended with `flags[].dynamic` and `flags[].generator` (reserved). Validation rules added: `A010` (dynamic flag on non-instanced challenge) and `A011` (static flag + `dynamic: true` conflict). - **`feat(generate)`: Prometheus scrape config generator** — `mctf generate` now emits `monitoring/prometheus.yml` with one scrape job per instanced challenge (sorted, deterministic).

Derived from the manifest, not declared separately. -- **22 challenge categories** — 10 core (web, pwn, crypto, reverse, forensics, osint, misc, ai, hardware, jailbreak), 12 opt-in extended, plus arbitrary custom slugs. -- **Per-category port-range allocation** (10000–17999, deterministic). -- **Source-of-truth vs derived files** separation. - -#### Validation -- **Schema-driven validation** (Draft 2020-12 JSON Schema). -- **Event-wide uniqueness checks** (port, subdomain, flag). -- **Static-flag image-leak guard** — scans `challenge/src/` for hardcoded flags before they bake into a public image. -- **Hard-fail vs warning catalog** — every rule has an ID for clean CI output. - -#### Generation -- **Auto-generated derived artifacts** — CTFd-format manifest, instancer `instance.toml`, `challenges.csv`, `index.json`, Traefik dynamic + static config. -- **Deterministic, idempotent** — same input → byte-identical output. -- **`--check` mode** — exits non-zero on drift; the CI gate that keeps sources and derived files locked together. - -#### Ingress (Docker mode + Traefik) -- **`mctf generate` emits Traefik config** — `ingress/traefik/traefik.yml` (entrypoints + file provider) and `ingress/traefik/dynamic/dynamic.yml` (HTTP routers/services for service archetype, TCP routers/services for `tcp: true` challenges). Backend URL points at `--1:` inside the docker network. Instanced challenges are skipped — they are routed by the instancer at game time. - -#### Inspection -- **`mctf list`** — table of every challenge in the event, with `--category` / `--archetype` / `--wave` / `--difficulty` filters; `--json` for scripting. -- **`mctf info /`** — show derived facts for one challenge: archetype, ingress URL, image-tag template, flag, file inventory; `--json` for machine-readable output. -- **`mctf categories`** — show the active category catalog (core + extended + custom) with port ranges and deployable flag. -- **`mctf status`** — runtime state of every challenge: docker compose project, container state (running/exited/missing), uptime, ingress URL. Static and instanced archetypes report synthetic states. `--json` for dashboards. -- **`mctf event`** — one-screen event summary: name/slug/domain/profile/flag-prefix/wave settings, total challenges, breakdowns by category / archetype / difficulty / wave, total assets size, list of authors. `--json` for dashboards. -- **`mctf completion bash|zsh|fish|powershell`** — emit the shell-completion script (cobra-generated) so contributors get tab-completion for every command and flag. -- **`mctf doctor`** — preflight checks: event config, challenge validation, docker binary/daemon/compose, git, registry creds, CTFd token, **host ports free for service-archetype challenges**; `--skip-env` and `--json` modes. - -#### Build -- **`mctf build`** — builds one container image per deployable challenge; tags `/--:` plus `:latest`; stamps `mctf.*` OCI labels; `--dry-run` previews commands; `--category` / `--slug` filters scope a build; `--push` ships to the registry. **Post-build leak scan** (on by default; `--scan=false` to disable) runs `docker create` + `docker export` and walks the image filesystem for any manifest flag value, exempting `flag.txt`/`FLAG`/`*.flag`. Build fails if a flag string is found in source code, configs, or other unexpected places. - -#### Deploy (Docker mode) -- **`mctf deploy`** — `docker compose up -d` for every service-archetype challenge; per-challenge project name `mctf---`; auto-stamps `PORT_` env so the compose's `${PORT_N:-N}` convention picks the right host port; instanced challenges are skipped (the instancer owns those at game time). -- **`mctf down`** — symmetric teardown in reverse-deploy order; `--volumes` to also drop named volumes. -- **`mctf logs /`** — stream logs from a deployed challenge's compose project; `-f` to follow, `--tail N` for the tail. -- **`mctf solve /`** — runs `solution/solve.sh` (or `solve.py` / `solve` binary) with `HOST` / `PORT` / `URL` / `FLAG_PREFIX` env, asserts the manifest flag appears in output. `--all` smoke-tests every solver; `--timeout` caps each run; `--json` for scripting. `--against-instance ` targets a live per-team instance instead of the deploy block: `HOST` / `PORT` / `URL` point at the instance's host-port mapping, `INSTANCE_ID` / `TEAM_ID` are stamped, and the per-team flag is accepted alongside the manifest flags. The challenge is resolved from the instance record. - -#### Notifications -- **Discord webhook** — set `MCTF_DISCORD_WEBHOOK` and `mctf deploy` / `mctf down` post embedded status messages (success/failure with the challenge list). Best-effort — webhook errors warn but never block the deploy. - -#### Native instancer (v0 — CLI mode) -- **`mctf instance spawn --team `** — bring up a per-team docker compose project for an instanced challenge with auto-allocated host ports (default range 30000–32999) and stamped `PORT_` / `INSTANCE_ID` / `TEAM_ID` / `FLAG` env. Idempotent per (team, challenge): re-running returns the existing instance. -- **`mctf instance destroy `** — tear down and remove from the store. `--force` cleans up store records even when the compose project is already gone; `--volumes` drops named volumes. -- **`mctf instance list`** — table of live spawns: id, slug, team, port mapping, time-to-expiry. `--json` for scripting. -- **`mctf instance extend --by 15m`** — bump expiry. -- **`mctf instance reap`** — destroy every expired instance (manual cleanup; the daemon mode that automates this lands later). -- State persists at `.mctf/instances.json` with atomic file rewrite + mutex protection. - -#### Native instancer (HTTP daemon) -- **`mctf instancer serve --addr :8080`** — long-running daemon. Bearer-token auth via `MCTF_INSTANCER_TOKEN` (comma-separated for rotation). Routes: - - `GET /healthz` — no-auth liveness probe - - `GET /instances` / `GET /instances/{id}` — list / fetch - - `POST /spawn` — `{team_id, challenge_slug, flag?}` (idempotent per team+chall) - - `POST /destroy/{id}` — tear down + remove from store - - `POST /extend/{id}` — `{by_seconds: N}` (default 900) -- **Reaper goroutine** — runs at `--reap-interval` (default 30s); calls `Down` + `Store.Delete` for every expired instance. Failed teardowns leave the record in the store so the next tick retries. -- **Graceful shutdown** — SIGINT/SIGTERM stops the reaper and gives in-flight requests 10s before close. -- `--quiet` discards docker compose stdout/stderr (recommended in production). - -#### Platform integration (CTFd) -- **`mctf platform sync`** — push challenges to the CTFd instance configured in `mctf.config.yml`. Diffs vs the platform's existing state, creates what's missing, attaches flags / tags / hints / **file uploads (assets/)**. Under `--update`, assets are matched by name and content (SHA1 vs CTFd's `sha1sum`), so an edited handout with the same filename is re-uploaded. `--dry-run` previews; `--category` / `--slug` filter; `--json` for scripting. Requires `MCTF_CTFD_TOKEN` env var. -- **`mctf platform configure`** — sync `ctf_name` from `event.name` to CTFd's `/api/v1/configs`. Theme settings are intentionally not synced (one-time UI setup). `--dry-run` previews. - -#### Distribution -- **Single static Go binary**, cross-platform. -- **GitHub Actions CI** runs Go build/test + schema sanity on every push and PR. -- **Embedded JSON Schemas** — no external file lookups at runtime. - -### Coming - -#### Build & deploy -- **Multi-mode deployment** — Docker (compose), SSH (single VPS), Kubernetes (cluster). -- **Opinionated profiles** — `simple` / `instanced` / `pro` curated presets. -- **Build-once-deploy-many** — images built ahead of time, deploys are near-instant pulls. -- **Container image registry integration** — Docker Hub, GHCR, others. -- **Auto-generated CI/CD pipelines** for the event repo (GitHub Actions, GitLab CI). -- **Compose / Kubernetes manifest generation** from the manifest. -- **Ingress & TLS routing** — Traefik (Docker mode), Nginx/IngressRoute (K8s mode). - -#### Runtime -- **Native instancer** — per-team isolated challenges, predictable naming, TTL cleanup, no Whaley dependency. -- **Per-team isolation** — containers under Docker, Pods under Kubernetes. -- **Dynamic flags** — per-team flag values minted at spawn time. -- **Resource limits & sandbox isolation** — `cpu` / `memory` / `pids` caps, `nsjail` / `redpwn/jail` for pwn. -- **Continuous health checks** with optional auto-restart. - -#### Infrastructure -- **Terraform wrapper** — `mctf infra plan|apply|destroy` for VPS, clusters, networking, DNS. -- **VPS provisioning templates** — DigitalOcean, Hetzner. -- **Cluster provisioning templates** — DOKS, EKS, GKE. -- **DNS automation** for `.` routing. -- **Autoscaling** under the `pro` profile. - -#### Observability & comms -- **Monitoring stack** — Prometheus + Grafana with prebuilt dashboards. -- **Container metrics** via cAdvisor. -- **Real-time notifications** — Discord webhooks (deploy success/failure, downtime, instancer errors);

rCTF and generic-webhook platforms via plugin. - -#### DX & ops -- **Live ports / disk / DNS preflight** — extend `mctf doctor` with port-availability, free-disk, and DNS-resolution checks. -- **Local dev mode** — full stack on a laptop with hot reload. -- **Per-challenge log streaming**. -- **Dry-run + safe teardown** — preview every change; tear environments down without orphans. - -#### Security -- **Secrets hygiene** — env-only, never on disk. -- **Network isolation** — explicit ports, ingress rules, per-event Docker network. -- **Privileged-mode policy** — warn under `simple`, block under `pro`. -- **Capability allowlist** — `cap_add` audited. - -#### Distribution -- **Homebrew tap, Scoop bucket, `.deb`/`.rpm`** via goreleaser. -- **Cross-platform binaries** — darwin-arm64/amd64, linux-amd64/arm64, windows-amd64. +### From source ---- +```sh +git clone https://github.com/MicroClub-USTHB/mctf-cli.git +cd mctf-cli && make build # produces ./mctf (needs Go 1.23+ and make) +``` -## Roadmap (versions) +## Quick start -| Version | Focus | -|---|---| -| **v0 (alpha, current)** | Phase 0 spec + Traefik ingress + native instancer (CLI + daemon) + Discord notifications + image-leak post-build scan + every command in the feature list. | -| **v0.1** | golangci-lint, goreleaser + Homebrew, K8s deploy, image-tag pinning + rollback, validate W003/W011/I001, docs refresh. | -| **v0.2** | SSH deploy, plugin system, dynamic flags, per-team auth on instancer, rCTF platform target. | -| **v0.3** | Terraform infra wrapper, Prometheus + Grafana, `pro` profile fully wired, image vulnerability scanning. | -| **v0.4** | Read-only web dashboard, generic-webhook platform target, additional cloud provisioning templates. | +```sh +mctf init my-ctf && cd my-ctf # scaffold an event repo +mctf init challenge web/welcome # scaffold a challenge +mctf validate # check against the spec +mctf generate # (re)write derived files +mctf build # build challenge images +mctf deploy # bring challenges up (docker compose) +mctf platform sync # push to CTFd +``` -See [`docs/BACKLOG.md`](docs/BACKLOG.md) for the full sized backlog with suggested wave-1 issues. +Run `mctf --help` for the full command set, or see +[`docs/commands.md`](docs/commands.md). + +## What it does + +**Author & validate** +- `mctf init` / `init challenge` scaffold an event and challenges from templates. +- Strict, schema-driven **validation** (JSON Schema Draft 2020-12) with + event-wide uniqueness checks, a static-flag image-leak guard, a committed-secret + scan (`doctor` D043), and a rule catalog with stable IDs for clean CI output. +- Three **archetypes** derived from the manifest: `static`, `service`, `instanced`. + +**Generate** +- Deterministic, idempotent **derived files** — CTFd manifest, instancer + `instance.toml`, CSV, `index.json`, Traefik ingress, Prometheus scrape config. +- `generate --check` fails CI on drift, keeping sources and derived files locked. + +**Build & deploy** +- `mctf build` — one image per deployable challenge, tagged `:` + `:latest`, + with a post-build flag-leak scan. +- `mctf deploy` / `down` in **three modes** — `docker` (compose + optional Traefik), + `ssh` (single VPS), `kubernetes` (manifests + `kubectl`). +- **Immutable image-tag pinning** for deterministic deploys and `--rollback`. + +**Per-team instancing** +- A built-in instancer (CLI + HTTP daemon) for per-team challenge instances, or + drive the dedicated [MCTF Instancer](https://github.com/MicroClub-USTHB/mctf-instancer) + service by setting `instancer.url` — the CLI then manages it over its admin API. + +**Operate** +- `mctf platform sync|unsync|configure` — CTFd integration (content-hash-aware + asset re-upload). +- `mctf monitoring up` — a Prometheus + Grafana + cAdvisor stack with scrape + config generated from your challenges. +- `mctf doctor` — preflight the repo and host;

The on-disk format works (50+ challenges, 10 categories, ran a real event), but the surrounding tooling fragmented into a Bun/TypeScript validator, a Windows `.bat` sync script calling Python `ctfcli`, hand-edited Traefik configs, and a separate "Whaley" instancer. **MCTF replaces all of it with one Go binary** that reads (almost) exactly the same on-disk format — challenge authors keep writing challenges the way they already do. +MCTF is the spiritual successor to the tooling that grew up around the +[MCTF 5.0 challenge repository](https://github.com/MicroClub-USTHB/MCTF-5.0-Challenges). +The on-disk format ran a real event (50+ challenges), but the surrounding +tooling had fragmented into a TypeScript validator, a `.bat` sync script, hand- +edited Traefik configs, and a separate instancer. **MCTF replaces all of it with +one Go binary** that reads (almost) exactly the same on-disk format — authors +keep writing challenges the way they already do. ## License
