After I upgrade my docker from 1.8.2-el7 to version 1.12.6, its failing to pull my private images from docker hub.
I could able to perform the list image command
sudo docker -H tcp://test-app01.local:2376 images
REPOSITORY TAG IMAGE ID CREATED SIZE
account/image1 tag1 a4c286f0ec9e 10 hours ago 864.7 MB
ubuntu latest d355ed3537e9 8 days ago 119.2 MB
account/image1 tag2 4abd8c3ed720 3 months ago 878.8 MB
But it's unable to pull latest image from repo with successful login.
sudo docker -H tcp://test-app01.local:2376 login -u username -p password
Login Succeeded
sudo docker -H tcp://test-app01.local:2376 pull account/image1:tag1
Using default tag: tag1
Pulling repository docker.io/account/image1
Error: image account/image1:latest not found
Can somebody please assist to fix this issue.
As you can see in the image command, you have only tag1 and tag2 image tags.
If you don't specify any, docker will look for latest which you don't have. So pull as this for tag1:
sudo docker -H tcp://test-app01.local:2376 pull account/image1:tag1
Or this for tag2:
sudo docker -H tcp://test-app01.local:2376 pull account/image1:tag2

Is it possible to push images to the Docker registry using podman?
I am running podman with the podman-docker (that claims to emulate the Docker CLI) package on fedora and I managed to successfully run docker login with my hub.docker.com credentials, but when I try to push an image it fails to connect.
It was enough to specify the address of the docker registry
docker push imageID docker://docker.io/username/ImageName:tag
For me, I had to be more explicit than the answer above:
podman system prune -a
podman login -u myuser -p mypassword docker.io/myuser/myimage
podman build -t localhost/myimage .
$ podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/myimage latest 1546573dd25d About a minute ago 716 MB
docker.io/library/docker 19.03.12-dind 66dc2d45749a 20 months ago 227 MB
podman push 1546573dd25d docker://docker.io/myuser/myimage:1.0.0
I did add dockerhub to my registries.conf. Not sure if its stricly required.
$ cat /etc/containers/registries.conf
[registries.search]
registries = ['docker.io', 'quay.io']
But I can just push as you would expect with docker.
podman build -t myuser/myimage .
podman login -u myuser
podman push myuser/myimage
podman version is 3.4.2
I am new to Docker. Can anyone help me in understanding the difference between
docker run img_name & docker pull img_name?
Do they work the same?
docker pull pulls an image or a repository from a registry.
docker run runs a command in a new container.
They don't work the same, however, if you use docker run with an image that you haven't pulled yet, docker run will call docker pull:
$ docker rmi hello-world

Please see docker help pull and docker help run for more information.
I installed docker on a raspberry-pi (Connected via ssh)
Installation is successful.
But running docker run hello-world produce no output.
Note on very first time I got additional messages regard installing image
Unable to find image 'hello-world:latest' locally

But there is no actual output from hello world script
Note I installed docker using command curl -sSL https://get.docker.com | sh
I tried following command too
sudo usermod -aG docker pi
sudo systemctl start docker
sudo docker run hello-world
Tried following commands docker ps -a

I ran into the same issue on a Raspberry Pi 1B+ (armv6l). Inspired by #JanDrábek's answer, the first observation is that the hello-world image would indeed be one supporting ARM, yet only after using hypriot/armhf-hello-world instead did I get the expected output:
$ uname -a
Linux 4.1.19+ #858 Tue Mar 15 15:52:03 GMT 2016 armv6l GNU/Linux
$ docker run hello-world # No output
$ docker image inspect hello-world | grep Architecture # Arch looks right though
"Architecture": "arm",
$ docker run hypriot/armhf-hello-world # This does the job
Hello from Docker.
This message shows that your installation appears to be working correctly.
run:
docker ps -a
and check if you can see the exited container.
take the container ID from the output and type
docker logs <ID>
this will allow you to see the logs.
if you want to see the output in the first place when you run it add -it flags to the run command
edit:
I tried in on my machine:
docker run -it hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.
maybe your output is redirected to some other stream.
try using :
docker run -it hello-world > ./test.txt 2>&1
after that check if the file has any content
I was having similar issue, my solution was definitely very naive but I basically removed all container and images and then tried again. It worked.
# Delete all containers
docker rm $(docker ps -a -q)
# Delete all images
docker rmi $(docker images -q)
I recently had same problem on my freshly installed Fedora 28 (up-to-date)... the containers all exited with exit code 139, the docker events said that it died, and docker logs said nothing.
My solution was to update the docker (or switch to CE edition) as the installed docker version was 1.13 which is quite old. (The tutorial for fedora https://docs.docker.com/install/linux/docker-ce/fedora/)
Also I have came across one potential thing to check... is your container compatible with your architecture (raspberry is ARM isn't it?) Use docker image inspect <image> search for Architecture.
Below are steps to reproduce the issue.
docker --version

Each docker run creates a new container.
To restart a container you can either run docker start 046a5d68c8b2 (following your example) or use the --restart=always option to docker run.

These are the methods tried to run the image , can anyone please help in running this edge pulled image.
