k8s部署ftp服务器

可以使用 Kubernetes 的 StatefulSet 来部署 FTP 服务器。首先，需要创建一个 PVC（Persistent Volume Claim）来存储 FTP 服务器的数据。然后，创建一个 ConfigMap 来存储 FTP 服务器的配置文件。最后，创建一个 StatefulSet 来部署 FTP 服务器。

以下是一个简单的 YAML 文件示例，用于部署 FTP 服务器：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ftp-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: ftp-config
data:
  vsftpd.conf: |
    listen=YES
    anonymous_enable=NO
    local_enable=YES
    write_enable=YES
    local_umask=022
    dirmessage_enable=YES
    xferlog_enable=YES
    connect_from_port_20=YES
    chroot_local_user=YES
    secure_chroot_dir=/var/run/vsftpd/empty
    pam_service_name=vsftpd
    rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
    rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: ftp-server
spec:
  serviceName: ftp-service
  replicas: 1
  selector:
    matchLabels:
      app: ftp-server
  template:
    metadata:
      labels:
        app: ftp-server
    spec:
      containers:
        - name: ftp-server
          image: fauria/vsftpd
          ports:
            - containerPort: 21
          volumeMounts:
            - name: ftp-data
              mountPath: /home/vsftpd
            - name: ftp-config
              mountPath: /etc/vsftpd
      volumes:
        - name: ftp-data
          persistentVolumeClaim:
            claimName: ftp-pvc
        - name: ftp-config
          configMap:
            name: ftp-config
