I'm loading tar file using:
$docker load -i C:/temp/new/testing.tar
Now I did:
$docker images
New image, "testingready", can be seen.
now I'm running this image:
$docker run testingready
Running on http://0.0.0.0:5000/
Restarting with stat
Debugger is active
Debugger PIN: 201-301-249
And my docker-machine ip is some xxx.yyy.zzz.aaa
Now I'm trying to run my application on xxx.yyy.zzz.aaa:5000 its not running,
As in parent system(where i created image) it running. I'm not getting where is the problem.

I have saved docker image and then load image.
$ sudo docker load -i e7bdb77cdcd8.tar
the images is loaded correctly
however i cannot start docker.
$ docker start e7bdb77cdcd8
Error response from daemon: No such container: e7bdb77cdcd8
Error: failed to start containers: e7bdb77cdcd8
docker start is used to start one or more stopped containers.
After you use docker load -i, it should load the artifact as a new docker image, you could see it using docker image ls.
Then, you should use docker run $your_loaded_image to run it.
I succefully ran hello-world using docker run command , but when I check running containers with docker ps , this container was not visble under running containers ,
Any suggestions
Thank

The default hello-world image from docker has no extra service running inside it so therefore exits after printing the default text. As such you cannot view it using docker ps which is command for viewing currently running containers.
To view running/stopped containers, run docker ps -a
See the image on how the docker ps and docker ps -a command show different results for the `hello-world image.
How did you run it? If I remember correctly, the hello world example just echos and quits, so running docker ps immediately afterwards won't show you anything.
Try this instead:
docker ps -n 1
That will essentially show you the most recent container you ran and its state.
Just for fun, if you really want to watch the hello-world execution at runtime...
Open up a new terminal window and run the command docker events, then keep watching what happens when you run docker run hello-world in your original terminal window.
Magically, you will see your entire container life-cycle below:
1.container create (notice the funny name= attribute of your ephemeral container name)
2.image pull
3.container init
4.container start
5.container attach
6.container died
7.container cleanup
Enjoy!
I created a docker container that is already running a the bash.
$ docker run -ti ubuntu bash
In a new terminal I check for the running containers:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
354449b423e1 ubuntu "bash" About a minute ago Up About a minute backstabbing_mestorf
Now I want to mount a drive that I have shared already on the running container without committing and creating a new image, neither pausing nor stopping it.So, I know
$ docker run ti -v /SrcDir:/Dest bash
The command above will create a new container but I don't want that. Is there a way where I will be able to mount and eject volumes from the host onto a running container?
I have created a docker image which is a python script based on a centos image. This image is working in the host system. Then I converted that image in tar.gz format. After that when I imported that tar.gz file into docker host(in a ubuntu system), it is done properly and the docker images list shows me the image listed in there. Then I tried to run the container in interactive mode using the following command:
$docker run -it image_name /bin/bash
it throws the following error:
docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"/bin/bash\\\": stat /bin/bash: no such file or directory\"\n".
Although docker run -it image_name /bin/bash command is working for all other images in my system. I tried almost all the means, but got no output apart from this error.
docker run -it image_name /bin/sh works for me! (Docker image, like Alpine, does not have /bin/bash).
I've just run into the same issue after updating Docker For Windows. It seems that it corrupted some image layers.
I cleared all the cached containers and images by running:
docker ps -qa|xargs docker rm -f
docker images -q|xargs docker rmi
The last command returned a few errors (some returned images didn't exist anymore).
Then I restarted the service and everything was running again.
I had the same issue, and it got resolved, after following the steps described in this post...
https://www.jamescoyle.net/how-to/1512-export-and-import-a-docker-image-between-nodes
Instead of saving the docker image (I) as .tar and importing, we need to commit the exited container, based on the image (I), as new image (N).
Then save the newly committed image (N) as .tar file, for importing into a new environment.
Hope this helps...
is there a way to save the contents of a container's "internal" HD. I have tried to use the docker commit but when I shut down the container and turn it on again, the contents that I have downloaded or generated inside the container (logs, etc) are gone.
When you start the container back up do you use docker start or docker run?
docker run -i -t docker/image /bin/bash will start a NEW container with the information from the original imagefile.
docker start {dockercontainerID} will restart a previously running container. you can get a list of previous dockers with docker ps -a
If you have save a docker with docker commit {runningdocker} docker/image2 you will use the new image name. ie `docker run -ti docker/image2 /bin/bash
