Kubernetes
在 Kubernetes 或 OpenShift 上运行 OpenHands 有不同的方式。本指南介绍了一种可能的方式:
- 作为集群管理员,创建一个 PV 将 workspace_base 数据和 docker 目录映射到 worker 节点上的 pod
- 创建一个 PVC 以便将这些 PV 挂载到 pod
- 创建一个包含两个容器的 pod:OpenHands 和 Sandbox 容器
上述示例的详细步骤
注意:确保首先使用适当的帐户登录到集群以执行每个步骤。创建 PV 需要集群管理员权限!
确保你对下面使用的 hostPath(即 /tmp/workspace)有读写权限
- 创建 PV: 集群管理员可以使用下面的示例 yaml 文件创建 PV。
- workspace-pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: workspace-pv
spec:

storage: 2Gi
accessModes:
- ReadWriteOnce

# 应用 yaml 文件
$ oc create -f workspace-pv.yaml

$ oc get pv

- 连接到 OpenHands UI,配置 Agent,然后测试:
GCP GKE OpenHands 部署
警告:此部署授予 OpenHands 应用程序访问 Kubernetes docker socket 的权限,这会带来安全风险。请自行决定是否使用。 1- 创建特权访问策略 2- 创建 gke 凭证(可选) 3- 创建 openhands 部署 4- 验证和 UI 访问命令 5- 排查 pod 以验证内部容器
