Kubernetes 安装 Plex Server

Plex 是一款集储存、索引、转码和在线播放的媒体库软件, 使用它可以在家庭内部搭建自己的媒体库. 官方有提供 plex server 的 docker 镜像, 这里可以直接使用它将 plex 安装到我的 Kubernetes 中.

安装 Plex

定义储存目录

首先定义一个储存媒体的地址, 这里储存在 master 的 /zfs-pool/media 目录下:

media-pv.yaml:

apiVersion: v1
kind: PersistentVolume
metadata:
name: media-pv
labels:
external: media
spec:
capacity:
storage: 500Gi
volumeMode: Filesystem
accessModes:
- ReadWriteMany # 此处使用 ReadWriteMany 是为了可以与 nextcloud 联动
persistentVolumeReclaimPolicy: Retain
storageClassName: local-storage
local:
path: /zfs-pool/media
nodeAffinity:
required:
nodeSelectorTerms:
- matchExpressions:
- key: kubernetes.io/hostname
operator: In
values:
- master

media-pvc.yaml:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: media-pvc
spec:
accessModes:
- ReadWriteMany
storageClassName: "local-storage"
resources:
requests:
storage: 500Gi
# 使用选择器选择特定的标签
selector:
matchLabels:
external: media

将此 pvc 挂载到 nextcloud 中即可使用 nextcloud 管理 plex 的媒体库文件.

接着给 plex 自身定义储存空间 (转码目录、配置目录等), 这里配置到 /zfs-pool/plex 下:

plex-pv.yaml:

storageClassName: "local-storage"
resources:

# 使用选择器选择特定的标签

app: plex

定义 Deployment

只是有点长, 但是也没有很难:

plex-deploy.yaml:

定义 Service

然后就是将它暴露出服务了, 虽然上面定义了很多的端口, 但是根据这篇文章里的说明, 以我的需求来说只需要暴露 32400 端口即可.

plex-svc.yaml:

1

spec:
ports:
- name: http
port: 32400
protocol: TCP
targetPort: 32400

定义 Ingress

将上面的 service 暴露出去就好啦!

secretName: xiaolanglang-net-wildcard-certificate

配置 Plex

安装插件

因为我们使用的刮削器(Scraper)会使用 XBMC 的格式储存元信息, 所以要使用插件 XBMCnfoMoviesImporter 让 plex 支持 XBMC 格式的元信息.

GitHub 上下载 zip 格式的压缩包, 解压, 并重命名为 XBMCnfoMoviesImporter.bundle, 然后将其拷贝到 Plug-ins 文件夹里即可.

此处的完整目录为 /zfs-pool/plex/config/Library/Application Support/Plex Media Server/Plug-ins

初始化 Plex

第一次初始化 Plex 服务器只能通过 localhost 进行, 这里使用端口转发来进行, 使用命令:

1
kubectl port-forward svc/plex 32400

然后打开浏览器, 访问 http://localhost:32400 即可进行配置.

配置网络

在 settings - Network - Enable Advanced Settings - Custom server access URLs 里添加上述的地址, 方便其他设备找到我们的服务器.
