GKE：nexus磁盘不可写入
我想在Google容器引擎中运行nexus3。
我创build了一个持久磁盘并configuration了以下部署文件：
apiVersion: apps/v1beta1 kind: Deployment metadata: name: nexus3 labels: app: nexus3 spec: replicas: 1 selector: matchLabels: app: nexus3 template: metadata: labels: app: nexus3 tier: web spec: containers: - image: gcr.io/nexustest-182520/nexus3:3.6.0 name: nexus3 volumeMounts: - mountPath: /nexus-data name: nexus3-persistent-storage ports: - containerPort: 8081 volumes: - name: nexus3-persistent-storage gcePersistentDisk: pdName: nexus3-disk fsType: ext4 部署失败，出现此问题：

我认为重启发生是因为联系本身无法启动。 我在日志中发现这个：
mkdir: cannot create directory '../sonatype-work/nexus3/log': Permission denied
和
Unable to update instance pid: Unable to create directory /nexus-data/instances
我的错误在哪里？ 需要做什么，使联系人写入磁盘和文件夹？
最好，拉尔斯
那么我在创build问题后直接自己解决了。 🙂
关于https://github.com/sonatype/docker-nexus3 ，应用程序运行在不同的pid上，然后是root。
把这个添加到部署文件中有一个诀窍：
spec: securityContext: fsGroup: 200
