但是几分钟后,它又自动开始了.有人知道如何解决这个问题吗?

推荐答案
此处提到的解决方案对我们有效.您基本上是创建矿工使用的文件,没有任何权利,因此矿工无法创建和使用它们. https://github.com/docker-library/redis/issues/217
The solution mentioned here worked for us. You basically create the files the miner uses, without any rights, so the miner cannot create and use them. https://github.com/docker-library/redis/issues/217
touch /tmp/kdevtmpfsi && touch /var/tmp/kinsing
echo "everything is good here" > /tmp/kdevtmpfsi
echo "everything is good here" > /var/tmp/kinsing
touch /tmp/zzz
echo "everything is good here" > /tmp/zzz
chmod go-rwx /var/tmp
chmod 1777 /tmp
