argo是云原生计算基金会的孵化项目 https://www.cncf.io/projects/。 Argo专为容器而设计，没有传统VM和基于服务器的环境的开销和限制，是一个基于kubernetes的CI/CD工具
目前CI(持续集成)方面还不完善，未提供event triggers（ https://github.com/argoproj/argo/blob/master/examples/README.md#continuous-integration-example ），最近有大改，可期待，参考PR https://github.com/argoproj/argo/pull/3488
可以看下另一个云原生的CI/CD工具 tekton (不推荐) 可参考https://my.oschina.net/u/160697/blog/4469399
argo目前还在发展中，现在是CNCF推荐的CI/CD工具。本人推荐现在用起来比argo更简单的drone。https://my.oschina.net/u/160697/blog/4487417
更多介绍参考官网 https://github.com/argoproj/argo
安装argo controller，以官方最新为准https://github.com/argoproj/argo/releases
kubectl create namespace argo kubectl apply -n argo -f https://raw.githubusercontent.com/argoproj/argo/v2.10.0-rc4/manifests/install.yaml
安装argo linux/mac客服端（可不安装，使用UI操作）
# Download the binary curl -sLO https://github.com/argoproj/argo/releases/download/v2.10.0-rc4/argo-linux-amd64.gz # Unzip gunzip argo-linux-amd64.gz # Make binary executable chmod +x argo-linux-amd64 # Move binary to path mv ./argo-linux-amd64 /usr/local/bin/argo # Test installation argo version
外网访问argo controller的Service（traefik https://my.oschina.net/u/160697/blog/4437939 ），官方也有登录方案，只是文档较少，选择自定义的一种方案
#通过以下命令生成(在线生成https://tool.oschina.net/htpasswd)帐号密码 #并替换Secret中的users sudo apt install apache2-utils echo $(htpasswd -nb admin gJv4EAfuXp5vFJ8)
替换第8行的users内容为上面echo的输出。增加basicAuth认证，增加认证后会增加Header(authorization)，argo会判断此header。所以需要增加一个中间件删除authorization
apiVersion: v1 kind: Secret metadata: name: argo-dashboard-auth-secret namespace: argo type: Opaque stringData: users: admin:$apr1$tQ1iFwRf$8SvGrGQcBT.RdZS73ULXH1 --- apiVersion: traefik.containo.us/v1alpha1 kind: Middleware metadata: name: argo-dashboard-auth namespace: argo spec: basicAuth: secret: argo-dashboard-auth-secret --- apiVersion: traefik.containo.us/v1alpha1 kind: Middleware metadata: name: remove-argo-auth-header namespace: argo spec: headers: customRequestHeaders: authorization: "" # Removes --- apiVersion: traefik.containo.us/v1alpha1 kind: IngressRoute metadata: name: argo-dashboard namespace: argo spec: entryPoints: - websecure routes: - kind: Rule match: Host(`argo.your_domain.com`) services: - name: argo-server port: 2746 middlewares: - name: argo-dashboard-auth - name: remove-argo-auth-header tls: certResolver: aliyun domains: - main: "argo.your_domain.com"
效果
创建一个官方默认的workflow。
需要注意的是namespace选择argo，spec下增加serviceAccountName: argo
使用kubectl apply -n argo -f https://raw.githubusercontent.com/argoproj/argo/v2.10.0-rc4/manifests/install.yaml创建时，只在命名空间argo里创建了ServiceAccount
如不修改会报以下错误：Failed to establish pod watch: unknown (get pods)
如需在其它命名空间使用，参考后面
如果需要在其它命名空间下创建workflow。需要创建ServiceAccount。以下为argo-rbac.yaml
#argo-rbac.yaml apiVersion: v1 kind: ServiceAccount metadata: name: workflow --- apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: name: workflow-role rules: # pod get/watch is used to identify the container IDs of the current pod # pod patch is used to annotate the step's outputs back to controller (e.g. artifact location) - apiGroups: - "" resources: - pods verbs: - get - watch - patch # logs get/watch are used to get the pods logs for script outputs, and for log archival - apiGroups: - "" resources: - pods/log verbs: - get - watch --- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: workflow-binding roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: workflow-role subjects: - kind: ServiceAccount name: workflow
创建ServiceAccount。可把default改为其它命名空间，创建后使用也必须加serviceAccountName: workflow
kubectl apply -n default -f argo-rbac.yaml
使用Workflow Template
增加一行serviceAccountName: workflow
创建后就可以通过此模板部署k8s程序
