# Argo CD Guide [Argo CD](https://argo-cd.readthedocs.io/) 是基于 [Kubernetes](https://kubernetes.io/) 的申明式、GitOps 持续部署工具。 本教程可以通过 [mde](https://github.com/LinuxSuRen/md-exec) 实现交互式体验。 ## 安装 首先，你需要有一套 [Kubernetes](https://github.com/kubernetes/kubernetes/) 环境。下面的工具可以帮助你快速按照好一套 Kubernetes 环境： > 推荐使用 [hd](https://github.com/LinuxSuRen/http-downloader) 安装下面的工具 > > 安装 `hd` 的命令为：`curl https://linuxsuren.github.io/tools/install.sh|bash` | 工具 | 工具安装 |使用 | |---|---|---| | [k3d](https://k3d.io/) | `hd i k3d` | `k3d cluster create` | | [kubekey](https://github.com/kubesphere/kubekey) | `hd i kk` | `kk create cluster` | | [minikube](https://github.com/kubernetes/minikube) | `hd i minikube` | `minikube start` | ```shell #!title: Install K3d hd i k3d ``` ```shell #!title: Reinstall K3d cluster k3d cluster delete k3d cluster create ``` 当 Kubernetes 环境就绪后，就可以通过下面的命令会在命名空间（`argo`）下安装最新版本的 `Argo CD`： ```shell #!title: Install ArgoCD kubectl create namespace argocd || true hd get https://raw.githubusercontent.com/argoproj/argo-cd/master/manifests/install.yaml kubectl apply -n argocd -f install.yaml || rm -rf install.yaml rm -rf install.yaml ``` 如果你的环境访问 GitHub 时有网络问题，可以使用下面的命令来安装： ```shell docker run -it --rm -v /root/.kube/:/root/.kube --network host --pull always ghcr.io/linuxsuren/argo-cd-guide:master ``` 查看初始化密码： ```shell #!title: Get Password kubectl -n argocd get secret argocd-initial-admin-secret -ojsonpath={.data.password} | base64 -d ``` 设置访问方式： ```shell kubectl -n argocd patch svc argocd-server --type='json' -p '[{"op":"replace", "path":"/spec/type", "value":"NodePort"}, {"op":"add", "path":"/spec/ports/0/nodePort","value":31518}]' # 暴露 k3d 端口 k3d node edit k3d-k3s-default-serverlb --port-add 31518:31518 ``` 推荐使用的工具： |||| |---|---|---| | [k9s](https://k9scli.io/) | `hd i k9s` | K9s is a terminal based UI to interact with your Kubernetes clusters. | | `argocd` | `hd i argoproj/argo-cd` | | ## 最佳实践 为了确保 YAML 格式正确，可以使用 [kubeconform](https://github.com/yannh/kubeconform) 对 [Argo CD 的 JSON SChema](https://github.com/argoproj/argo-cd/issues/9348) 进行校验。 ## 一个简单的示例 执行下面的命令后 ```shell #!title: Create A Sample App +f cat <<EOF | kubectl apply -n argocd -f - apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: learn-pipeline-go spec: destination: namespace: default server: https://kubernetes.default.svc project: default source: repoURL: https://gitee.com/devops-ws/learn-pipeline-go # 示例工程 path: kustomize # 从该目录下查找 Kubernetes 文件 targetRevision: HEAD kustomize: namePrefix: foo EOF ``` 更多应用的例子请查看： * [SonarQube](examples/sonarqube.md) * [Harbor](examples/harbor.md) ## 概念 TODO ## 同步策略 Argo CD 可以[指定 Git 仓库中的特定目录](https://argo-cd.readthedocs.io/en/stable/user-guide/directory/)，已经一些通用配置： ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: sample spec: source: repoURL: https://github.com/devops-ws/learn-pipeline-go targetRevision: HEAD path: kustomize # 指定父目录 directory: recurse: true # 支持遍历子目录 exclude: '{config.json,env-usw2/*}' # 忽略部分 include: '*.yaml' # 包含所有 YAML 文件 syncPolicy: syncOptions: - CreateNamespace=true automated: prune: true selfHeal: true ``` 设置[同步策略](https://argo-cd.readthedocs.io/en/stable/user-guide/sync-options/)： ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: sample spec: syncPolicy: syncOptions: - CreateNamespace=true # 自动创建命名空间 automated: prune: true # Git 库中删除的资源，也会在集群中删除 selfHeal: true ``` ## 模板工具 TODO ## Git 仓库 Argo CD 支持 HTTPS、SSH 协议的 Git 仓库，下面的例子中使用的是 SSH 协议： ```yaml apiVersion: v1 data: insecure: dHJ1ZQ== project: ZGVmYXVsdA== sshPrivateKey: eW91ci12YWx1ZQ== type: Z2l0 url: Z2l0QGdpdGh1Yi5jb206ZGV2b3BzLXdzL2FyZ28tY2QtZ3VpZGUuZ2l0 kind: Secret metadata: labels: argocd.argoproj.io/secret-type: repository # 表明这会被 Argo CD 识别为仓库（Git、Helm 等） name: repo-1108037796 # 以 repo- 为前缀的名称，通过 UI 创建时会自动生成 namespace: argocd type: Opaque ``` ## Helm 仓库 > 截至 v2.5.2 Argo CD 界面还支持添加 Helm 类型的仓库，可以通过命令行或者 YAML 的方式来添加。 ```yaml apiVersion: v1 data: enableOCI: dHJ1ZQ== name: c2staGVsbQ== project: ZGVmYXVsdA== type: aGVsbQ== url: cmVnaXN0cnktMS5kb2NrZXIuaW8= kind: Secret metadata: labels: argocd.argoproj.io/secret-type: repository name: repo-skywalking-helm namespace: argocd type: Opaque ``` OCI 类型的 Helm 仓库安装示例请查看 [examples/skywalking](examples/skywalking.md) ## Webhook TODO ``` https://ip:port/api/webhook ``` ## 配置管理插件 配置管理工具（Config Management Plugin，CMP）使得 Argo CD 可以支持 Helm、Kustomize 以外的（可转化为 Kubernetes 资源）格式。 例如：我们可以将 [GitHub Actions 的配置文件转为 Argo Workflows](https://github.com/LinuxSuRen/github-action-workflow/) 的文件，从而实现在不了解 Argo Workflows 的 `WorkflowTemplate` 写法的前提下，也可以把 Argo Workflows 作为 CI 工具。 > 下面的例子中需要用到 Argo Workflows，请自行安装，或查看[这篇中文教程](https://github.com/LinuxSuRen/argo-workflows-guide)。 我们只需要将插件作为 sidecar 添加到 `argocd-repo-server` 即可。下面是 sidecar 的配置： ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: argocd-repo-server namespace: argocd spec: template: spec: containers: - args: - --loglevel - debug command: - /var/run/argocd/argocd-cmp-server image: ghcr.io/linuxsuren/github-action-workflow:master imagePullPolicy: IfNotPresent name: tool resources: {} securityContext: runAsNonRoot: true runAsUser: 999 volumeMounts: - mountPath: /var/run/argocd name: var-files - mountPath: /home/argocd/cmp-server/plugins name: plugins ``` 然后，再添加如下 Argo CD Application 后，我们就可以看到已经有多个 Argo Workflows 被创建出来了。 ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: yaml-readme namespace: argocd spec: destination: namespace: default server: https://kubernetes.default.svc project: default source: path: .github/workflows/ # It will generate multiple Argo CD application manifests # base on YAML files from this directory. # Please make sure the path ends with slash. plugin: {} # Argo CD will choose the corresponding CMP automatically repoURL: https://gitee.com/linuxsuren/yaml-readme # a sample project for discovering manifests targetRevision: HEAD syncPolicy: automated: selfHeal: true ``` 由于用到 PVC 作为 Pod 之间的共享存储，我们还需要安装对应的依赖。如果是测试环境，可以安装 [OpenEBS](https://openebs.io/docs/user-guides/installation)。并设置其中的 为[默认存储卷](https://kubernetes.io/zh-cn/docs/tasks/administer-cluster/change-default-storage-class/)： ```shell kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}' ``` 如果需要用到 Git 凭据的话，可以通过下面的命令拿到： ```shell kubectl create secret generic git-secret --from-file=id_rsa=/root/.ssh/id_rsa --from-file=known_hosts=/root/.ssh/known_hosts --dry-run=client -oyaml ``` 这一点对于 Argo Workflows 落地为持续集成（CI）工具时，非常有帮助。如果您觉得 GitHub Actions 的语法足够清晰，那么，可以直接使用上面的插件。或者，您希望能定义出更简单的 YAML，也可以自行实现插件。插件的核心逻辑就是将目标文件（集）转为 Kubernetes 的 YAML 文件，在这里就是 `WorkflowTemplate`。 如果再发散性地思考下，我们也可以通过自定义格式的 YAML（或 JSON 等任意格式）文件转为 Jenkins 可以识别的 Jenkinsfile，或其他持续集成工具的配置文件格式。 ## 凭据管理 可以通过下面的命令，生成一个加密后的 Secret： ```shell kubectl create secret generic test --from-literal=username=admin --from-literal=password=admin --dry-run=client -oyaml -n default | kubeseal -oyaml ``` 下面是生成 Docker 认证信息的命令： ```shell kubectl create secret docker-registry harbor --docker-server='10.121.218.184:30002' \ --docker-username=admin --docker-password=password \ --dry-run=client -oyaml -n default | kubeseal -oyaml ``` ## 单点登录 Argo CD [内置了 Dex 服务](https://argo-cd.readthedocs.io/en/stable/operator-manual/user-management/#dex)，我们可以参考如下的配置来对接外部身份认证服务： ```yaml apiVersion: v1 kind: ConfigMap metadata: name: argocd-cm namespace: argocd data: url: https://10.121.218.184:31392 # argo-cd server 的地址 dex.config: | logger: level: debug connectors: - type: gitlab

假如用户组名为 dev policy.default: role:org-readonly scopes: '[groups, email]' ``` 对于通用的 OAuth 认证，可以访问下面地址获取相关信息： `https://10.121.218.184:31392/api/dex/.well-known/openid-configuration` ## 多集群 ```shell #!title: Create New Cluster cat <<EOF | kubectl apply -n argocd -f - apiVersion: v1 data: config:

可以自动更新应用的镜像，参考配置如下： ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: server namespace: argocd annotations: argocd-image-updater.argoproj.io/image-list: 10.121.218.184:30002/al-cloud/console:master argocd-image-updater.argoproj.io/update-strategy: digest ``` ## 通知 Argo CD 内置了[消息通知模块](https://argo-cd.readthedocs.io/en/stable/operator-manual/notifications/)，只要添加下面的 ConfigMap 即可，这里以发送消息到钉钉为例： ```yaml apiVersion: v1 kind: ConfigMap metadata: name: argocd-notifications-cm
