数周以来,我一直遇到 ftps-filezilla 和 Kubernetes 的问题。
语境:
我有一个使用 Kubernetes 和 ftps 的学校项目。我需要在端口 21 的 kubernetes 中创建一个 ftps 服务器,并且它需要在 alpine linux 上运行。因此,我使用 docker 容器创建了我的 ftps-alpine 服务器的映像。我测试它,看它是否可以自行正常工作:使用docker run --name test-alpine -itp 21:21 test_alpine
我在 filezilla 中有此输出:
Status: Connecting to 192.168.99.100:21…
Status: Connection established, waiting for welcome message…
Status: Initializing TLS…
Status: Verifying certificate…
Status: TLS connection established.
Status: Logged in
Status: Retrieving directory listing…
Status: Calculating timezone offset of server…
Status: Timezone offset of server is 0 seconds.
Status: Directory listing of “/” successful
它成功运行,filezilla 看到了我的 ftps 目录中的文件,现在我很好(在主动模式下工作)。
问题:
所以我想要的是在我的 kubernetes 集群中使用我的镜像(我使用 Minikube)。当我将我的 docker 镜像连接到 kubernetes 中的 ingress-service-deployment 时,我得到了:
Status: Connecting to 192.168.99.100:30894...
Status: Connection established, waiting for welcome message...
Status: Initializing TLS...
Status: Verifying certificate...
Status: TLS connection established.
Status: Logged in
Status: Retrieving directory listing...

我尝试了什么:

ssl_sslv2=NO
ssl_sslv3=NO
allow_writeable_chroot=YES
#listen_port=21
pasv_address=192.168.99.100
- 将 pasv_min 和最大端口从 20 更改为 20、从 20 更改为 21 以及从 30000 更改为 34000(nodeport 范围)。
- Listen=YES 和 Listen_ipv6=NO 等等。
- 我确实尝试了被动模式和主动模式。
- 我已将 pasv_address 设置为我的 minikube ip。
这是我在 stackoverflow 上提出的问题:https://stackoverflow.com/questions/60458028/ftps-server-doesnt-work-properly-using-kubernetes
问题:
除了我的 kubernetes 集群,我怎样才能成功获取第一条消息?
如果您有任何疑问需要澄清,没问题。
