作为 root:工件创建的卷装载，尽管提供了安全上下文

Question

问题：将 Artifactory 部署为 Kubernetes 中的部署。VolumeMounts 正在作为 drwxr-sr-x 的 root：artifact 和权限进行挂载

/var/opt/jfrog/artifactory
drwxr-sr-x    2 root     artifact      4096 Jan 24 17:52 etc
/var/opt/jfrog/artifactory/etc
-rw-r--r--    1 root     artifact      1048 Jan 24 17:48 artifactory.config.import.yml
-rw-r--r--    1 root     artifact     12703 Jan 24 17:48 artifactory.system.properties

预期：卷装载应作为项目装载 项目：具有读写权限的项目

由于限制，Kubernetes 清单文件不完整

spec:
securityContext:
runAsUser: 1030
runAsGroup: 1030
fsGroup: 1030

mountPath: "/var/opt/jfrog/artifactory/etc/artifactory.config.import.yml"

Kubernetes 版本：

Server Version: version.Info{
Major: "1",
Minor: "14",
GitVersion: "v1.14.1",
GitCommit: "b7394102d6ef778017f2ca4046abbaa23b88c290",

BuildDate: "2019-04-08T17:02:58Z",
GoVersion: "go1.12.1",
Compiler: "gc",
Platform: "linux/amd64"
}

我相信安全上下文涵盖了所需的

runAsUser: 1030

以 1030 身份运行进程

runAsGroup: 1030

指定 runAsGroup 时，创建的任何文件也将归用户 1030 和组 1030 所有。 运行

fsGroup: 1030

附加的任何卷的所有者将是组 ID 1099 的所有者。

码头工人文件路径

不知道为什么容器会出现错误的用户所有权，任何帮助将不胜感激。

错误：

Answer 1

我所要做的就是添加一个 initContainer 并将 Configmaps 挂载到/tmp 并将其移动到必要的路径/var/opt/jfrog/artifactory/etc/，而不是将配置映射挂载在卷挂载/var/opt/jfrog/artifactory 中。

原因：ConfigMaps 是只读的，因此/etc 过去是，将来也永远是只读的。

initContainers:
- name: "grant-permissions"
image: "busybox:1.26.2"
securityContext:
runAsUser: 0
imagePullPolicy: "IfNotPresent"
command:
- 'sh'
- '-c'
- 'mkdir /var/opt/jfrog/artifactory/etc ; cp -vf /tmp/artifactory* /var/opt/jfrog/artifactory/etc ; chown -R 1030:1030 /var/opt/jfrog/ ; rm -rfv /var/opt/jfrog/artifactory/lost+found'
volumeMounts:
- mountPath: "/var/opt/jfrog/artifactory"
name: artifactory-volume
- name: bootstrap
mountPath: "/tmp/artifactory.config.import.yml"
subPath: bootstrap
readOnly: false
- name: artifactory-system-properties
mountPath: "/tmp/artifactory.system.properties"
subPath: artifactory.system.properties
readOnly: false

然后将卷装载到运行工件的主容器

containers:
- name: artifactory
image: "registry.eu02.dsg.arm.com/sqa/artifactory-pro:6.17.0"
volumeMounts:
- name: artifactory-volume
mountPath: "/var/opt/jfrog/artifactory"

Answer 2

如此处、此处、此处和此处所述，您无法更改挂载目录的权限。

作为解决方法，您可以使用在实际容器之前运行的initContainer来更改对目录的权限：

initContainers:
- name: volume-mount
image: busybox
command: ["sh", "-c", "chown -R 1030:1030 <your_directory>"]
volumeMounts:
- name: <your volume>
mountPath: <your mountPath>
