What happened

When I use Aliyun OSS to store the checkpoint, the configuration is as follows, the storage is successful, and I can find the checkpoint from the OSS file. I deployed the seatunnel server using Docker. When I restart, the real-time synchronization tasks I previously established disappear, and the server does not reload historical tasks from the checkpoint. Does seatunel have the ability to reload historical tasks from checkpoint？

seatunnel:
engine:
history-job-expire-minutes: 1440
backup-count: 1
queue-type: blockingqueue
print-execution-info-interval: 60
print-job-metrics-info-interval: 60
slot-service:
dynamic-slot: true
checkpoint:
interval: 10000
timeout: 600000
storage:
type: hdfs
max-retained: 3
plugin-config:
storage.type: oss
namespace: /tmp/seatunnel/checkpoint_snapshot
oss.bucket: oss://xxx
fs.oss.accessKeyId: xxx
fs.oss.accessKeySecret: xxx
fs.oss.endpoint: oss-cn-hangzhou.aliyuncs.com

I also encountered this issue, but now I've been utilizing Ali OSS HDFS to store my checkpoints successfully. I suggest you consider testing this solution!

我存储成功了，但是如果重启docker的话不会读取checkpoint，所有任务都丢失了
