Kafka helm chart：java.io.IOException：无法创建数据目录/opt/kafka/data/logs

Question

我知道这个问题已经存在，但它与 Kubernetes 或容器有关。

图表存储库：https://github.com/helm/charts/tree/master/incubator/kafka

helm install kafka-test incubator/kafka

我在使用 helm charts 安装 Kafka 时遇到以下异常。

Answer 1

这是权限相关的问题。我检查了 values.yaml 文件。

有一个属性

## Optional Container Security context
securityContext: {}

我已将该值更改为以 root 用户身份在下方点赞

## Optional Container Security context
securityContext:
  runAsUser: 0

Answer 2

运行它作为特权容器。

securityContext:
  runAsUser: 0
  privileged: true
