I am trying to learn docker so i installed official docker application from it's site and after installing i installed kitematic.I am using windows 10:

PS D:\Software\Windows\Docker\Kitematic-Windows>
After running kitamatic and search busybox and clicked on create after a few second i got this error:
(HTTP code 500) server error - Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on 192.168.65.1:53: read udp 192.168.65.3:57485->192.168.65.1:53: i/o timeout
to test i used terminal to create container :
PS D:\Software\Windows\Docker\Kitematic-Windows> docker run busybox

What's happen ?
Your machine is using 192.168.65.1 as DNS server to resolve the IP for registry-1.docker.io.
In a lot of places, it's suggested to go in the settings and change the DNS from Automatic to Fixed: 8.8.8.8

I had an issue with docker running on a raspberry pi 4 and I purged all of it apart from the folder with the containers/images.
Reinstalled docker, run helloworld, runs ok. Installed portainer to manage the containers, several of them start but a particular one, homeassistant, doesn't
It reports
pi#raspberrypi:~ $ docker start homeassistant
Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/7c4732337e167e0f8178b8667bddc0393c2c1e4f7ffba5d68fe57379cc1de7c0/merged: no such file or directory

diff link lower work
I've checked the overlay2 folder and indeed there's no merged folder. I've tried creating an empty one, but it gets deleted as soon as I attempt starting the container. What does this folder indicate when it comes to the container and how do I work around it? Ideally I would like to keep the container as otherwise I would have to set up the whole thing again.
I'm learning docker and installing it in my VPS by this post. But it don't work
when I run
docker pull hello-world it causes errors like this.
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
And this is result when i run docker info

I tried some ways on google like disable firewall, setup proxy, reset vps, reinstall docker but it still didn't work. Hope everyone help me
I would like to test some docker swarm features and for that I have a windows PC and a mac book pro, both in my private Network.
I installed Docker for Windows (Windows 10 pro, using linux containers) and also Docker for mac.
Then I started both of them and also configured my router to allow the ports they need for TCP and UDP:
Port 2377 TCP for node communication
Port 7946 TCP/UDP for container network discovery.
Port 4789 UDP for the container ingress network.
Also I deactivated the firewall both on my pc and on my mac.
Then I ran docker swarm init on my macbook, which gave me a join token.
On my windows PC I entered that join command in the console and....... it failed!
I got an error message that ends with "... connection refused".
So, can you give me some advise or links to how to properly connect to local machines via docker swarm? I would LOVE to test it and use it for local development and testing of my apps. thanks!

The problem is that netiher docker Desktop for Mac nor for Windows with Linux containers are "true" dockers. Both are using virtual machines with Linux os where true docker engine works.
If I'm correct, 192.162.65.3 is not the IP of your Mac but the IP of vm within some virtual mac network.
Basing on this article https://docs.docker.com/docker-for-mac/docker-toolbox/ and this sentence "Also note that Docker Desktop for Mac can’t route traffic to containers, so you can’t directly access an exposed port on a running container from the hosting machine." Connecting Mac and Windows on Linux containers might not be easy.
I'd recommend for testing either get some cloud VMs or on Windows you can use docker-machine command to spawn multiple Linux VMs on which you can setup local swarm to test features you wish.

Currently, Amazon Linux is not supported distribution. There are't any official packages for that distro moreover, docker it is not tested on it.
It seems this error is raised by cgroups package
You can try to run this script to check if anything is missing or misconfigured.
I meet the problem when running the deploy sh of Shipyard. The error is
docker: Error response from daemon: driver failed programming external connectivity on endpoint shipyard-proxy (): Bind for 0.0.0.0:2375 failed: port is already allocated.
Then I use netstat -ntple command to find out who is listening port 2375.
The result is dockerd itself.
So I wonder how to overcome this problem in order to finish the installation of Shipyard.
And here is the docker ps
My docker info result is showed below
