+# Github Actions 도입하기
+
+## 1. Self hosted runner 등록하기
+
+os 이미지 빌드의 무거움을 해소하기 위해 self hosted runner 사용
+
+```bash
+# Create a folder
+$ mkdir actions-runner && cd actions-runnerCopied!# Download the latest runner package
+$ curl -o actions-runner-linux-x64-2.325.0.tar.gz -L https://github.com/actions/runner/releases/download/v2.325.0/actions-runner-linux-x64-2.325.0.tar.gzCopied!# Optional: Validate the hash
+$ echo "5020da7139d85c776059f351e0de8fdec753affc9c558e892472d43ebeb518f4  actions-runner-linux-x64-2.325.0.tar.gz" | shasum -a 256 -cCopied!# Extract the installer
+$ tar xzf ./actions-runner-linux-x64-2.325.0.tar.gz
+
+# Create the runner and start the configuration experience
+$ ./config.sh --url https://github.com/yucori/bootc-practice --token {MY_TOKEN}# Last step, run it!
+$ ./run.sh
+
+# Use this YAML in your workflow file for each job
+runs-on: self-hosted
+```
+
+- runner 등록 과정에서 Must not run with sudo 문제 발생
+  ⇒ `export RUNNER_ALLOW_RUNASROOT="1"` 으로 문제 해결
+  - 원래 runner는 root 사용이 비권장되지만, bootc를 통해 os 이미지를 관리하기 위해서 root로 runner 실행하도록 함
+
+## 2. workflow 작성
+
+```yaml
+name : Build & Push
+
+on:
+  push:
+      branches: [main]
+  workflow_dispatch:
+
+jobs:
+  build:
+    runs-on: self-hosted
+    steps:
+    - uses: actions/checkout@v4
+    - name: Install Podman
+      run: sudo apt install -y podman
+
+    - name: Build an image
+      run: podman build -t bootc:latest /root
+
+    - name: Login Registry
+      run: podman login -u ${{ secrets.REGISTRY_USER }} -p ${{ secrets.REGISTRY_PW }} docker.io
+
+    - name: Push an Image
+      run: podman push bootc:latest docker.io/${{ secrets.REGISTRY_USER }}/bootc:latest
+
+```
+
+- workflow 작성 후 secrets 변수들 등록
+- runner를 run.sh로 단순 실행했다가 터미널이 종료되면 runner가 listen을 못하기에 nohup을 통해 백그라운드로 실행
+  - `nohup ./run.sh & > nohup.out`

+
+빌드 후 도커 허브에 업로드까지 완료!
+
+이 김에 push 시에 디코로 알림이 오도록 설정
+
+디코에 채널 만들고 webhook 링크를 깃헙에 등록
+
