Argo CD 搭配 Kustomize 實作 GitOps 部署 周育緯 1 About me •III DevOps contributor •8 年 System, DevOps 與 Backend 開發與 維護經驗 •資展國際、工研院: Kubernetes, DevOps 講師 2 GitOps •雲原生 Continuous Deployment •所有部署都使用聲明式(declarative)腳本 Repoitory •https://github.com/demoyuw/k8s-summit- cd-repository.git •Git clone https://github.com/demoyuw/k8s-summit- cd-repository.git •cd k8s-summit-cd-repository 9 10 kustomization.yaml 定義四個類別 •resources: kustomize overlay/development | kubectl apply -f - 20 部署出dev deployment and service env 21 Argo CD 22 •A declarative, GitOps continuous delivery tool for Kubernetes 用ArgoCD 搭配kustomize來部署環境ㄌ 23

創建並進入一個工作目錄: mkdir /tmp/debian-tutorial ; cd /tmp/debian-tutorial 3 把 dash 原始碼套件下載下來 apt-get source dash (務必確保 deb-src 已加入 /etc/apt/sources.list) 4 構建套件 cd dash-* debuild -us -uc (-us -uc 代表不使用GPG來簽署套件) (若不確定套件種類屬於哪一種, 請使用非原生) ▶ 原生套件: 通常指的是在 Debian 上固有的特定軟體(dpkg, apt) ▶ 非原生套件: 在 Debian 以外發展的軟體 ▶ 主要檔案: .dsc (描述資料內容) ▶ 其他檔案則相依於原始碼格式版本 ▶ 1.0 or 3.0 (原生): package_version.tar.gz ▶ 1.0 (非原生): ▶ pkg_ver.orig simgrid_3.6.orig.tar.gz) ▶ 解開此 tar 檔 ▶ 將目錄改名為 - (範例: simgrid-3.6) ▶ cd - && dh_make (來自 dh-make 套件) ▶ 對於特定套件, 有除了 dh_make 以外的方法, 舉例為: dh-make-perl

concurrency. 您會需要設定新的 Crate，然後下載並準備執行依附元件。接著就能將範例複製貼上至 src/main.rs， 使用這些範例進行實驗： cargo init concurrency cd concurrency cargo add tokio --features full cargo run 形式 本課程極具互動性，因此建議您根據各項疑問，帶領學員瞭解 Rust！ 1.2 鍵盤快速鍵 exercise Created binary (application) `exercise` package 3. 前往 exercise/，使用 cargo run 建構並執行二進位檔： $ cd exercise $ cargo run Compiling exercise v0.1.0 (/home/mgeisler/tmp/exercise) Finished dev [unoptimized 該都有自己的模 組。 Cargo Setup Rust Playground 僅支援一個檔案，因此您需要在本機檔案系統中建立 Cargo 專案： cargo init gui-modules cd gui-modules cargo run 請編輯產生的 src/main.rs，新增 mod 陳述式並在 src 目錄中新增其他檔案。 來源 以下是 GUI 程式庫的單一模組實作項目： pub

GKE。這類範本系統通常缺 乏彈性，以及程式碼化應用程式管理的重複性，因此可能增加維護成本。 14.原生AWS/GCP/Azure整合 如果Kubernetes發行版本無法在目標基礎架構執行，那麼簡易的多雲部署就沒有什 麼用處。Canonical Kubernetes、OpenShift及Rancher都能與以下三種主要的公 有雲原生整合：Amazon Web Services(AWS)、Google Cloud Platform(GCP)及 Platform(GCP)及 Microsoft Azure。 15.原生Openstack/VMware整合 至於在私有雲方面，三種Kubernetes發行版本均能與OpenStack及 VMware原生整合。 16.裸機部署及自動化 並非所有工作負載都適合虛擬化，而企業有時需要直接在裸機伺服器部署 Kubernetes。雖然這三種發行版本都支援裸機部署，但只有Openshift及 Canonical 高可用性 叢集升級 支援生命週期 邊緣支援 單節點版本 – 託管Kubernetes方案 – 容器執行階段即登錄檔 聯網 儲存 監控及作業管理 多元部署 原生AWS/GCP/Azure 整合 原生Openstack/VMware 整合 裸機部署及自動化 GPGPU支援加速工作負載 安全性 支援的架構 價格 $ $$$$$ $$$ Canonical RedHat
