To achieve Persistence storage in native container or host based we can mount host drive, But if the host is down data will be lost because its not shared.
Another option can be using NFS setup and mounting volume in container, But this will lead another problem of Slowness and if NFS Server is down everything is down.
Do we have any other Highly Available,Secure solution to setup persistence storage with Multi Host sharing.

How to fix this problem?
Looks like you're in Windows Container, you need to switch to Linux Container.
Then, wait for docker restart and retry.
Is there a bug in the docker containerwait api?The logs show that it stops at the containerwait function, but I found out via docker ps -a that the container has ended and exitcode=0. With 2000+ containers created, there is a 1 in 100 chance that this will happen.When I create a smaller number of containers, this does not happen. Has anyone experienced the same problem?
Can I implement a waitcontainer api myself by polling the container state?Are there any problems with this approach?

I am currently using a Docker Swarm with limit-cpu, limit-memory and reserve cpu and memory.
After done my testing I would like to remove these configurations. I couldn't find any article for how to remove these.
Is there anyway to remove these setting by update without delete and recreate the docker service?

You can use docker service update full documentation can be found here -> https://docs.docker.com/engine/reference/commandline/service_update/
To update or remove the cpu and memory limits you could run this command
docker service update --limit-cpu 0 --limit-memory 0 --reserve-cpu 0 --reserve-memory 0 service_name

I need to do an multi-host networking using swarm and i was following this link Lab 06: Docker Networking
They have mentioned to edit /etc/default/docker file to comment out DOCKER_OPTS value. But i couldnt see any file in my host machine. Where could i find this file to change the value of DOCKER_OPTS
The guide is for debian based systems that use /etc/default in Redhat based systems use:
/etc/sysconfig
in your case:
/etc/sysconfig/docker
You can edit the systemd unit file directly for your purpose, but its not recommended.
I am trying to use docker cp to copy .class files from my host into the container. I am using the following command:
docker cp foo.class container:/path/foo.class
I am doing this when the server running inside the container is shutdown.
However, I am seeing that the foo.class isn't getting updated with my latest file and if I try to rm the file I get a
rm: cannot remove foo.class: Stale file handle
Here is my docker version (Docker for Mac):
