### سه لایه Docker-in-Docker:
|
||||
```
|
||||
K3s containerd (لایه ۱)
|
||||
└── gitea-runner Pod → docker container (DinD daemon) (لایه ۲)
|
||||
└── workflow: docker run / docker build (لایه ۳)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📁 فایلهای Workflow
|
||||
|
||||
### 🐳 K8s Pipelines (Docker + K3s) — آفلاین
|
||||
|
||||
| سرویس | فایل | Branch | Image | Deploy |
|
||||
|--------|------|--------|-------|--------|
|
||||
| CMS | `kub-deploy.yml` | `kub-stage` | `admin/cms` | SSH → kubectl |
|
||||
| BackOffice | `kub-deploy.yml` | `kub-stage` | `admin/backoffice` | SSH → kubectl |
|
||||
| FrontOffice | `kub-deploy.yml` | `kub-stage` | `admin/frontoffice` | SSH → kubectl |
|
||||
| CMS | `prod-deploy.yml` | `production` | `admin/cms:prod` | SSH → kubectl |
|
||||
| BackOffice | `prod-deploy.yml` | `production` | `admin/backoffice:prod` | SSH → kubectl |
|
||||
| FrontOffice | `prod-deploy.yml` | `production` | `admin/frontoffice:prod` | SSH → kubectl |
|
||||
|
||||
### 🪟 Windows/IIS Pipelines (Legacy) — آنلاین
|
||||
|
||||
| سرویس | فایل | Branch | Target |
|
||||
|--------|------|--------|--------|
|
||||
| CMS | `cms-stage.yml` | `stage_new` | IIS → `cms.kbs1.ir` |
|
||||
| BackOffice | `bo-stage.yml` | `stage-new` | IIS → `admin.kbs1.ir` |
|
||||
| FrontOffice | `fo-stage.yml` | `stage-new` | IIS → `kbs1.ir` |
|
||||
|
||||
> ⚠️ Stage pipeline ها از Windows runner + IIS استفاده میکنن و Docker ندارن.
|
||||
|
||||
### ساختار مشترک Pipeline:
|
||||
```
|
||||
1. Start Docker daemon (DinD)
|
||||
2. Checkout code (git clone)
|
||||
3. Login to Docker registries (32082 + 30080)
|
||||
4. [CMS only] Publish Protobuf packages
|
||||
5. Build Docker Image
|
||||
6. Push to Registry
|
||||
7. Deploy to Kubernetes (SSH → kubectl rollout restart)
|
||||
```
|
||||

||||
|
||||
## 🐛 مشکلات حلشده و راهحلها
|
||||
|
||||
### مشکل ۱: `iptables failed: Permission denied`
|
||||
|
||||
**خطا:**
|
||||
```
|
||||
iptables v1.8.10 (nf_tables): Could not fetch rule set generation id: Permission denied
|
||||
```
|
||||
|
||||
**علت:** K3s containerd به Docker daemon اجازه تغییر iptables نمیده.
|
||||
|
||||
**راهحل:** غیرفعال کردن networking در dockerd:
|
||||
```bash
|
||||
dockerd --iptables=false --ip6tables=false --bridge=none --storage-driver=vfs &
|
||||
```
|
||||
|
||||
> ⚠️ با `--bridge=none` نیاز به شبکهسازی Docker نیست چون فقط build و push انجام میشه.
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۲: `failed to unmount overlayfs: operation not permitted`
|
||||
|
||||
**خطا:**
|
||||
```
|
||||
failed to register layer: unshare: operation not permitted
|
||||
```
|
||||
|
||||
**علت:** `overlay2` storage driver نیاز به mount namespace داره که داخل K3s مجاز نیست.
|
||||
|
||||
**راهحل:** استفاده از `vfs` storage driver:
|
||||
```bash
|
||||
dockerd --storage-driver=vfs &
|
||||
```
|
||||
|
||||
> ⚠️ `vfs` کندتره ولی هیچ mount syscall خاصی نیاز نداره. برای CI/CD کافیه.
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۳: `no basic auth credentials` هنگام pull ایمیج
|
||||
|
||||
**خطا:**
|
||||
```
|
||||
Error response from daemon: Head "https://194.5.195.53:32082/v2/dotnet/sdk/manifests/9.0":
|
||||
no basic auth credentials
|
||||
```
|
||||
|
||||
**علت:** `docker login` فقط قبل از push انجام میشد، ولی `docker build` (یا `docker run`) هم از `32082` ایمیج pull میکنه.
|
||||
|
||||
**راهحل:** اضافه کردن step "Login to Docker registries" بلافاصله بعد از Checkout:
|
||||
```yaml
|
||||
- name: Login to Docker registries
|
||||
run: |
|
||||
echo "${{ secrets.REGISTRY_PASSWORD }}" | docker login 194.5.195.53:32082 -u admin --password-stdin
|
||||
echo "${{ secrets.REGISTRY_PASSWORD }}" | docker login ${{ env.REGISTRY }} -u admin --password-stdin
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۴: `unshare: operation not permitted` هنگام extract لایهها
|
||||
|
||||
**خطا:**
|
||||
```
|
||||
docker: failed to register layer: unshare: operation not permitted
|
||||
```
|
||||
|
||||
**علت اصلی (دو بخش):**
|
||||
|
||||
**بخش ۱:** Gitea act_runner دیفالت `container.privileged: false` داره. یعنی job container ها بدون privileged ساخته میشن — حتی اگه workflow بنویسه `options: --privileged`.
|
||||
|
||||
**بخش ۲:** env var `CONFIG_FILE` در runner container ست نبود → `run.sh` فلگ `--config` رو به `act_runner daemon` پاس نمیداد → config.yaml اصلاً لود نمیشد!
|
||||
|
||||
**راهحل (سمت سرور):**
|
||||
|
||||
۱. ساخت ConfigMap:
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: runner-config
|
||||
namespace: default
|
||||
data:
|
||||
config.yaml: |
|
||||
log:
|
||||
level: info
|
||||
runner:
|
||||
file: .runner
|
||||
capacity: 1
|
||||
timeout: 3h
|
||||
container:
|
||||
privileged: true
|
||||
options: "--security-opt seccomp=unconfined --security-opt apparmor=unconfined"
|
||||
valid_volumes:
|
||||
- "**"
|
||||
```
|
||||
|
||||
۲. Mount کردن در Deployment + env var:
|
||||
```bash
|
||||
kubectl patch deployment gitea-runner --type=json -p='[
|
||||
{"op":"add","path":"/spec/template/spec/containers/1/env/-",
|
||||
"value":{"name":"CONFIG_FILE","value":"/data/config.yaml"}},
|
||||
{"op":"add","path":"/spec/template/spec/containers/1/volumeMounts/-",
|
||||
"value":{"name":"runner-config","mountPath":"/data/config.yaml","subPath":"config.yaml"}},
|
||||
{"op":"add","path":"/spec/template/spec/volumes/-",
|
||||
"value":{"name":"runner-config","configMap":{"name":"runner-config"}}}
|
||||
]'
|
||||
```
|
||||
|
||||
> ⚠️ **نکته مهم:** بدون `CONFIG_FILE=/data/config.yaml` env var، فایل `run.sh` داخل act_runner image فلگ `--config` رو پاس نمیده!
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۵: Protobuf restore از nuget.org بجای Nexus
|
||||
|
||||
**علت:** `dotnet restore` بدون `--configfile` از دیفالت NuGet sources استفاده میکنه.
|
||||
|
||||
**راهحل:**
|
||||
```bash
|
||||
dotnet restore "$proj" --configfile src/NuGet.config
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۶: عدم دسترسی شبکه با `--bridge=none`
|
||||
|
||||
**علت:** `dockerd --bridge=none` شبکه Docker bridge رو غیرفعال میکنه. در نتیجه container هایی که با `docker run` یا `docker build` ساخته میشن، دسترسی شبکه ندارن (مثلاً `dotnet restore` نمیتونه به Nexus وصل بشه).
|
||||
|
||||
**راهحل:** استفاده از `--network host` در `docker run` و `docker build`:
|
||||
```bash
|
||||
# Protobuf step
|
||||
docker run --rm --network host -v $(pwd):/src -w /src ...
|
||||
|
||||
# Build step
|
||||
DOCKER_BUILDKIT=0 docker build --network host -t ... .
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### مشکل ۷: `failed to prepare ... as ...: invalid argument` (BuildKit)
|
||||
|
||||
**خطا:**
|
||||
```
|
||||
ERROR: failed to build: failed to solve: failed to prepare xxx as yyy: invalid argument
|
||||
```
|
||||
|
||||
**علت:** BuildKit (بیلدر پیشفرض Docker ≥23) از snapshotter overlay استفاده میکنه که با `--storage-driver=vfs` سازگاری نداره.
|
||||
|
||||
**راهحل:** غیرفعال کردن BuildKit:
|
||||
```bash
|
||||
DOCKER_BUILDKIT=0 docker build --network host -t ... .
|
||||
```
|
||||
|
||||
> ⚠️ Legacy builder از vfs بدون مشکل استفاده میکنه.

## 🔄 تغییرات prod-deploy (قدیم → جدید)
|
||||
|
||||
| مورد | قدیم (prod-deploy) | جدید |
|
||||
|------|-------------------|------|
|
||||
| Container image | `docker:latest` | `docker-sshpass:latest` (شامل sshpass + git) |
|
||||
| Proxy | `HTTP_PROXY` + `HTTPS_PROXY` | حذف شد (آفلاین) |
|
||||
| Registry | `gitea-svc:3000` + external | فقط `194.5.195.53:30080` |
|
||||
| kubectl | `apk add` + `curl` از اینترنت | SSH → `kubectl` مستقیم روی سرور |
|
||||
| Auth | hardcoded password | `secrets.REGISTRY_PASSWORD` + `secrets.SERVER_PASSWORD` |
|
||||
| BuildKit | فعال (دیفالت) | `DOCKER_BUILDKIT=0` |
|
||||
| Network | Docker bridge (دیفالت) | `--network host` |
|
||||
| dockerd | دیفالت | `--iptables=false --ip6tables=false --bridge=none --storage-driver=vfs` |
|
||||
| Deploy | `KUBECONFIG_PROD` (base64) | SSH + sshpass (مثل kub-stage) |
|
||||
|
||||
> ✅ حالا همه ۶ K8s pipeline (۳ stage + ۳ prod) از **یک الگوی مشترک آفلاین** استفاده میکنن.

## 🔑 Secrets مورد نیاز (Gitea → Settings → Secrets)
|
||||
|
||||
| Secret | استفاده |
|
||||
|--------|---------|
|
||||
| `REGISTRY_PASSWORD` | پسورد Docker registry (admin) |
|
||||
| `SERVER_PASSWORD` | پسورد SSH سرور (root) |

|
||||
|
||||
## 🔧 dockerd فلگهای نهایی
|
||||
|
||||
```bash
|
||||
dockerd --iptables=false --ip6tables=false --bridge=none --storage-driver=vfs &
|
||||
```
|
||||
|
||||
| Flag | دلیل |
|
||||
|------|-------|
|
||||
| `--iptables=false` | K3s اجازه تغییر iptables نمیده |
|
||||
| `--ip6tables=false` | مشابه بالا برای IPv6 |
|
||||
| `--bridge=none` | نیازی به Docker bridge network نیست |
|
||||
| `--storage-driver=vfs` | overlay2 نمیتونه mount کنه داخل K3s |
|
||||
|
||||

|
||||
|
||||
## 🔍 عیبیابی Pipeline
|
||||
|
||||
### ۱. چک وضعیت Runner:
|
||||
```bash
|
||||
# SSH به سرور
|
||||
ssh root@194.5.195.53
|
||||
|
||||
# آیا runner pod بالاست؟
|
||||
kubectl get pods -l app=gitea-runner
|
||||
|
||||
# لاگ runner
|
||||
kubectl logs <pod-name> -c runner --tail=30
|
||||
|
||||
# لاگ DinD
|
||||
kubectl logs <pod-name> -c docker --tail=30
|
||||
```
|
||||
|
||||
### ۲. تست Docker داخل Runner:
|
||||
```bash
|
||||
# exec به DinD container
|
||||
kubectl exec <pod-name> -c docker -- docker info
|
||||
|
||||
# آیا registry قابل دسترسیه؟
|
||||
kubectl exec <pod-name> -c docker -- docker pull 194.5.195.53:32082/dotnet/sdk:9.0
|
||||
```
|
||||
|
||||
### ۳. چک config runner:
|
||||
```bash
|
||||
# آیا config.yaml mount شده؟
|
||||
kubectl exec <pod-name> -c runner -- cat /data/config.yaml
|
||||
|
||||
# آیا privileged فعاله؟
|
||||
kubectl exec <pod-name> -c docker -- docker inspect <job-container> \
|
||||
--format '{{.HostConfig.Privileged}} {{.HostConfig.SecurityOpt}}'
|
||||
```
|
||||
|
||||
### ۴. ریاستارت runner:
|
||||
```bash
|
||||
kubectl rollout restart deployment/gitea-runner
|
||||
kubectl rollout status deployment/gitea-runner --timeout=120s
|
||||
```
