So I try running some docker application on My local network it works fine without any problem.
But when I try access it from public IP address it doesn't allow Me to connect
Ex: http://SomePublicIp then browser return with
SSH-2.0-OpenSSH_8.4p1 Debian-5+deb11u1
but when I try with local IP it works normally
the return of docker ps

Using 7fc72b887e23 as the ID of the namenode, when I get to the command
$ docker cp ../hadoop-mapreduce-examples-2.7.1-sources.jar cb0c13085cd3:hadoop-mapreduce-examples-2.7.1-sources.jar
I get an error:
$: command not found
Not sure what I am doing wrong.
Remove the $ at the beginning. That's what $: command not found means. Easy to miss when copy pasting code
docker cp ../hadoop-mapreduce-examples-2.7.1-sources.jar cb0c13085cd3:hadoop-mapreduce-examples-2.7.1-sources.jar
When I run docker info, it shows that I have 18 containers running.
% docker info
Client:
Debug Mode: false
Server:
Containers: 18
Running: 18
Paused: 0
Stopped: 0
Images: 9
...
I want to delete these containers, but when I run docker container ls -a, it shows an empty list. How can I find them?
These containers are not allowing me to delete images.
% docker rmi -f 1e94481e8f30
Error response from daemon: conflict: unable to delete 1e94481e8f30 (cannot be forced) - image is being used by running container 7e9b08a0007b
You are probably running kubernetes.
After stopping kubernetes, to remove all stopped containers and all images without at least one container associated to them:
docker system prune --all
To stop all running containers
docker stop $(docker ps -a -q)
To remove all containers
docker rm $(docker ps -a -q)
You should be able to delete all images after that
Those 18 containers belong to Kubernetes. You can check this by going to the Preferences > Kubernetes > Check Show system containers (advanced).
After that, just run docker container ls -a again and you will see those 18 containers.
These are the containers you are not seeing unless you check that option:

I setup my kafka containers by follow the tutorial from here: https://success.docker.com/article/getting-started-with-kafka
Then I found that I can't remove the container anymore, even though I tried docker container prune. The containers are still running.
What should I do?

I found I have to use docker service rm to remove the service due to the replicas settings.
The prune command doesn't work against running containers. You will need to either stop or kill them.
docker kill caa0b94c1d98
I am running Docker for Mac(Edge) and I have a Kubernetes Cluster.
I am trying to be able to run a Registry inside Kubernetes, so I can push images to the cluster and use them in a Localhost environment.
I have installed a Registry with Helm: helm install stable/docker-registry
And I am able to run with portforward:
export POD_NAME=$(kubectl get pods --namespace default -l "app=docker-registry,release=guiding-hedgehog" -o jsonpath="{.items[0].metadata.name}")
echo "Visit http://127.0.0.1:8080 to use your application"
kubectl port-forward $POD_NAME 8080:5000
The problem is that I get an error when trying to push to the registry with docker push localhost:5000/hello:
The push refers to repository [localhost:5000/hello]
Get http://localhost:5000/v2/: dial tcp [::1]:5000: getsockopt: connection refused
kubectl get services:
NAME: eyewitness-moose-docker-registry TYPE: ClusterIP CLUSTER-IP:10.106.213.130 EXTERNAL-IP:<none> PORT(S):5000/TCP
Note: Also tried adding docker.for.mac.localhost:5000 to list of insecure registries.
So it looks like a security issue, and might be related to that it is not possible to run an insecure registry described in Docker doc
Therefore I have created a certificate as described here.
Now the question is, how do I distribute the certificate to each node with only kubectl?
Note: I am running in Docker for Mac(Edge), so I can get to the Kubernetes running containers. But there is so many and how and I don't think that is is the right way:

I was surprised twice when found that some of them alive. Since festive_bhabha is up I would like attach to it:
sudo docker attach festive_bhabha
But command prints nothing and not returns. Why I can't attach to container?
Docker containers are not automatically removed when they exist. You can clean dangling images, exited containers... using:
docker system prune
The Docker container festive_bhabha seems to be an ubuntu image that might not be generating and output, which explains why no output is shown when running the attach command.
You can check what processes are running inside this container by running:
docker container top festive_bhabha
Alternatively, you can exec inside the container.
docker exec -it festive_bhabha bash
