在 GKE 的 cronjob 中使用 rollout restart 命令
Using the rollout restart command in cronjob, in GKE
我想使用 k8s cronjob 定期重启部署。
请检查yaml文件有什么问题
当我从本地命令行执行命令时,部署正常重启,但似乎无法通过 cronjob 重启。
例如 $ kubectl rollout restart deployment my-ingress -n my-app
我的 cronjob yaml 文件
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: deployment-restart
namespace: my-app
spec:
schedule: '0 8 */60 * *'
jobTemplate:
spec:
backoffLimit: 2
activeDeadlineSeconds: 600
template:
spec:
serviceAccountName: deployment-restart
restartPolicy: Never
containers:
- name: kubectl
image: bitnami/kubectl:latest
command:
- 'kubectl'
- 'rollout'
- 'restart'
- 'deployment/my-ingress -n my-app'
正如 David 建议的那样 运行 kubectl 的 cron 就像执行命令
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: hello
spec:
schedule: "*/5 * * * *"
jobTemplate:
spec:
template:
spec:
serviceAccountName: sa-jp-runner
containers:
- name: hello
image: bitnami/kubectl:latest
command:
- /bin/sh
- -c
- kubectl rollout restart deployment my-ingress -n my-app
restartPolicy: OnFailure
我还建议您检查角色和服务帐户权限
参考示例:
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
namespace: default
name: kubectl-cron
rules:
- apiGroups:
- extensions
- apps
resources:
- deployments
verbs:
- 'patch'
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
name: kubectl-cron
namespace: default
subjects:
- kind: ServiceAccount
name: sa-kubectl-cron
namespace: default
roleRef:
kind: Role
name: kubectl-cron
apiGroup: ""
---
apiVersion: v1
kind: ServiceAccount
metadata:
name: sa-kubectl-cron
namespace: default
