# DevOps Runbook: Provider Build Pipeline

This folder describes the full pipeline from API discovery to provider + docs publication.

## Read This First

1) Start here: `devops/README.md` (this file).
1a) Architecture: `devops/ARCHITECTURE.md`.
1b) Mandatory suspend lifecycle policy: `docs/60_strategy/provider_philosophy.md` (sections 7-9).
2) Service list: `devops/config/services_list.txt`.
2a) Operation timeouts config: `devops/config/operation_timeouts.json`.
3) Unified YAML generator: `universal_rebuild/tools/service_spec_gen`.
4) Go resource generator: `universal_rebuild/tools/gen_v2`.
5) Docs generator: `devops/02_generate_resources_and_docs_v2.sh`.
6) Build + publish scripts: `devops/03_build_and_upload_provider.sh`, `devops/04_build_and_publish_docs.sh`.

## Overview (end-to-end)

1) Fetch all service metadata from API
2) Generate unified YAML specs from API
3) Generate Go resources + documentation files from unified YAML
4) Build provider binaries for 3 OS targets and upload to Registry
5) Build and publish documentation site

## Generator code locations

- Unified YAML from API: `universal_rebuild/tools/service_spec_gen`
- Go resources from YAML: `universal_rebuild/tools/gen_v2`
- Docs generator: `devops/02_generate_resources_and_docs_v2.sh`

## Prerequisites

- Go 1.22+
- `python3`
- `gpg`
- `mc` (MinIO/S3 client)
- Docker (for mkdocs build)

## Shared settings

S3 environment:
- `S3_ENDPOINT` (example: `https://s3.msk-1.ngcloud.ru`)
- `S3_ACCESS_KEY`
- `S3_SECRET_KEY`

Tip: the local S3 config lives at `secrets/.s3cfg_registry`.

Operation timeouts config:
- Source of truth: `devops/config/operation_timeouts.json`
- During provider build, this file is copied into embedded provider config by `devops/03_build_and_upload_provider.sh`.

Provider naming defaults:
- `REGISTRY_HOSTNAME`: `terra.k8c.ru`
- `NAMESPACE`: `nubes`
- `NAME`: `nubes`

## Stand profiles (TEST/PROD/DEV)

To avoid overwrite between stands, use per-stand profiles:

- `devops/profiles/test`
- `devops/profiles/prod`
- `devops/profiles/dev`

Each profile contains:

- `profile.env` (API URL, token file, versions, S3/GPG paths)
- `services_list.txt`
- `operation_timeouts.json`
- `generated/` (`resources_yaml`, `go`, `docs`, `json`, `tmp`)

Run scripts with profile path:

```bash
./devops/01_generate_yamls.sh --profile devops/profiles/test
./devops/02_generate_resources_and_docs_v2.sh --profile devops/profiles/test
./devops/03_build_and_upload_provider.sh --profile devops/profiles/test
./devops/04_build_and_publish_docs.sh --profile devops/profiles/test
```

`--profile` is required for generation/build scripts in strict mode.
Generated artifacts are stored only in `devops/profiles/<stand>/generated/*`.
`universal_rebuild` is treated as code-only source directory.

## Step 1: Generate unified YAML from API

Script: `01_generate_yamls.sh`

Input list of services:
- `config/services_list.txt` (service_id only)

Token options:
- `TOKEN_FILE=<repo_root>/HH-MM-SS.token`, or
- `NUBES_API_TOKEN` directly

Example:
```bash
export TOKEN_FILE=<repo_root>/08-33-41.token
./devops/01_generate_yamls.sh
```

Outputs:
- YAML files in `universal_rebuild/resources_yaml` (file names use `ID_name.yaml`)

Note:
- Every run regenerates all YAML specs from the API for the services listed in `services_list.txt`.
- This overwrites previous YAMLs and ensures resources/docs match the current API for that list.
- Before generation, the scripts clean old YAML and generated Go files, so each run starts from a clean slate.

## Step 2: Generate Go resources and docs

Script: `02_generate_resources_and_docs_v2.sh`

Example:
```bash
./devops/02_generate_resources_and_docs_v2.sh
```

Outputs:
- Go files in `universal_rebuild/internal/resources_gen`
- Docs in `docs/30_registry/resources`

## Step 3: Build and upload provider

Script: `03_build_and_upload_provider.sh`

Uses `registry-server-build/build-provider.sh` and signs with:
- `secrets/private_key.asc` (ignored by git)

Example:
```bash
export S3_ENDPOINT=https://s3.msk-1.ngcloud.ru
export S3_ACCESS_KEY=...
export S3_SECRET_KEY=...
./devops/03_build_and_upload_provider.sh 2.0.2
```

## Step 4: Build and publish docs

Script: `04_build_and_publish_docs.sh`

Example:
```bash
export S3_ENDPOINT=https://s3.msk-1.ngcloud.ru
export S3_ACCESS_KEY=...
export S3_SECRET_KEY=...
./devops/04_build_and_publish_docs.sh 2.0.2
```

## Notes

- The GPG private key must remain stable across releases. Do not regenerate per build.
- If the key is regenerated, the registry server must be updated to serve the new public key.
- Terraform will fail with `authentication signature from unknown issuer` if the registry public key does not match the signing key.
- `config/services_list.txt` is the source of truth for which services are generated.
- If the provider version changes, update `universal_rebuild/main.go`.

## Quickstart (fresh run)

```bash
# 0) Prepare token
export TOKEN_FILE=<repo_root>/HH-MM-SS.token

# 1) Generate YAML specs from API
./devops/01_generate_yamls.sh

# 2) Generate Go resources + docs
./devops/02_generate_resources_and_docs_v2.sh

# 3) Build + upload provider
./devops/03_build_and_upload_provider.sh 2.0.2

# 4) Build + publish docs
./devops/04_build_and_publish_docs.sh 2.0.2
```

## Troubleshooting checklist

- If YAML generation fails: check token, API endpoint, and `/tmp/yaml_gen_failures.txt`.
- If docs are missing: run `02_generate_resources_and_docs_v2.sh`.
- If registry rejects artifacts: verify GPG key and public key in registry server.

## One-time GPG bootstrap (do this once, keep the key stable)

1) Generate and export keys (no passphrase):
```bash
GPG_DIR=<repo_root>/secrets
GNUPGHOME=$(mktemp -d)
cat > /tmp/gpg_batch <<'EOF'
%no-protection
Key-Type: RSA
Key-Length: 4096
Subkey-Type: RSA
Subkey-Length: 4096
Name-Real: tazet@narod.ru
Name-Email: tazet@narod.ru
Expire-Date: 0
EOF
gpg --batch --homedir "$GNUPGHOME" --gen-key /tmp/gpg_batch
gpg --batch --homedir "$GNUPGHOME" --armor --export-secret-keys > "$GPG_DIR/private_key.asc"
gpg --batch --homedir "$GNUPGHOME" --armor --export > "$GPG_DIR/public_key.asc"
rm -rf "$GNUPGHOME" /tmp/gpg_batch
```

2) Update registry server public key (ASCII Armor) in:
- `registry-server-build/main.go`
- `operator/cmd/registry/main.go`

3) Rebuild and redeploy the registry server (see `docs/50_history/00_system_mechanics.md`).

4) Build and upload provider artifacts as usual.

## Token and self-run shortcuts

Token capture (JSON from F12):
```bash
cat token.json | ./devops/00_token_manager.sh save -
```

Use latest token automatically:
```bash
./devops/12_generate_yamls_latest.sh
```

10-run stability test (latest token):
```bash
REQUEST_DELAY=0.3 ATTEMPTS=3 ./devops/11_yaml_stability_run_latest.sh
```

Log output:
```bash
tail -n 200 /tmp/yaml_gen_runs.log
```

## Legacy (deprecated)

- Ops YAML and ops-doc generators were removed after the unified YAML migration.

## Docs build policy (updated)

- `mkdocs`/`mkdocs-material` are **not** installed on every docs generation run.
- Preferred path: build docs in Docker (`squidfunk/mkdocs-material`) via `04_build_and_publish_docs.sh`.
- Fallback path: local `mkdocs` is used only if it is already installed.
- If local `mkdocs` is missing, install once in persistent virtualenv and reuse.

One-time setup example:

```bash
python3 -m venv .venv
.venv/bin/pip install mkdocs mkdocs-material
```

Then run docs publish normally:

```bash
./devops/04_build_and_publish_docs.sh <version>
```
