I am trying to push docker image into docker hub, but i am not able to push docker image into docker hub.
You need to push in the following manner (ensure you are logged into docker on the command line)
docker push <dockerusername>/test-img:<tag>
Make sure you also build your image as:
docker build -t <dockerusername>/test-img <Dockerfile>

I have a git repository from where I am trying to build and publish a docker image to docker hub.
Some how I am keep on getting Unauthorised for docker login step.
Any Help is appreciated.

You should first login to docker hub by typing the command docker login it will prompt the user name and after that password of docker hub after that try pushing the image again to docker hub
I am not that sure if this is what you have asked for but in order to push images to docker hub , first you need to build your docker image. then create a repository on docker hub with the name you want. and then do something like this
docker build -f ./Dockerfile -t nametoyourlocalimage:version . //this will build your docker image locally
docker tag nametoyourlocalimage:version YourDockerHubNewReporUrlYouJUstCreated
docker login //this will prompt you to enter your username and password
docker push YourDockerHubNewRepoUrlYouJUstCreated
docker logout
I am no MacOS installed Docker Desktop.
I have a private registry in Docker Hub.
I have two Dockerfiles in my project, each for one image. Both images are built successfully:
# 1st image
docker build -t myusername/my-app:1.0.3 -f Dockerfile .
# 2nd image
docker build -t myusername/my-proxy:1.0.0 -f proxy/Dockerfile .
On terminal, I firstly login with my docker id myusername:
$ docker login -u myusername docker.io
Password:
Login Succeeded
Then, I push my first image:
$ docker push myusername/my-app:1.0.3
The push refers to repository [docker.io/myusername/my-app]

The push is successful!
Then I try to push my second image:
docker push myusername/my-proxy:1.0.0
The push refers to repository [docker.io/myusername/my-proxy]

However the 2nd image push to docker registry is denied. Why is that? Where could be wrong for my 2nd image push?
I am new to Docker and trying to push the Docker image to the hub..giving me the below error.
docker container run hellowold
This is v2
docker image tag hellowold:2 prateekaxyz/hellowold:latest
docker login http://hub.docker.com --username=prateek512
Password:

docker push prateekaxyz/hellowold:latest
The push refers to a repository [docker.io/prateekaxyz/hellowold]

You need to first tag your image before pushing
docker tag firstimage YOUR_DOCKERHUB_NAME/firstimage
And then you can push it.
docker push YOUR_DOCKERHUB_NAME/firstimage
reference: https://intellipaat.com/community/207/denied-requested-access-to-the-resource-is-denied-docker
you should login first. suppose you have an account in https://hub.docker.com/
as name/password= prateekaxyz/bar.
before push, you should
docker login -u prateekaxyz -p bar
after login success, you can push image to docker hub under your namespace
note that your image should begin with your name, eg prateekaxyz/aa:version
This helped me:
Build the image with the following format:
docker build -t [docker-id]/reponame .
which will by default be given "latest" as tag
and then run:
docker push [docker-id]/reponame:latest
I am following the instructions for the custom-vision service on raspberry-pi on IOT edge.
I have reached step 3, where in VS Code I am executing Build and Push to IOT Edge Solution and this is triggering the following command:
docker build --rm -f "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/CameraCapture/arm32v7.Dockerfile" -t registry.hub.docker.com/v1/repositories/myname/iot-hub-1/cameracapture:0.2.7-arm32v7 "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/CameraCapture"
&& docker push registry.hub.docker.com/v1/repositories/myname/iot-hub-1/cameracapture:0.2.7-arm32v7
&& docker build --rm -f "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/ImageClassifierService/arm32v7.Dockerfile" -t registry.hub.docker.com/v1/repositories/myname/iot-hub-1/imageclassifierservice:0.2.4-arm32v7 "/Users/myname/Dropbox/Dev/azure/custom-vision/Custom-vision-service-iot-edge-raspberry-pi/modules/ImageClassifierService"
&& docker push registry.hub.docker.com/v1/repositories/myname/iot-hub-1/imageclassifierservice:0.2.4-arm32v7
Which is failing with 404 - page not found.
I also tried using cloud.docker.com/repository/registry-1.docker.io/myname/iot-hub-1 but this gave me a different error:
invalid argument
"cloud.docker.com/repository/docker/myname/iot-hub-1:latest/cameracapture:0.2.7-arm32v7"
for "-t, --tag" flag: invalid reference format
Can anyone assist with the correct URL path, or some the additional steps i need to uploading the containers to my docker hub repository?
I couldn't find the correct URL for dockerhub, but Azure Container Registry was able to resolve my problem.
Details of the URL are here: Raspberry PI / IOTEdge failing to pull from Azure Container Registry
You need docker login first. Then build image docker build -t <docker_hub_username>/<app_name>:<tag> and then just push docker push <docker_hub_username>/<app_name>:<tag>. You don't need to specify any specific URL for Docker Hub.
Use this:
docker push <hub-user>/<repo-name>:<tag>
i.e
docker push username/reponame:latest
I'm migrating a project from a private registry to hub.docker.com but I don't have all tagged image on computer.
I have access to the registry machine via SSH.
Question
How can I push all my registry images to hub.docker.com?
I think that the only way is to pull them all, then retag them and push to hub.docker.com
You can script it with something like:
for repository in $(curl -s http://localhost:5000/v2/_catalog | jq -r '.repositories[]'); do
for image in $(curl -s http://localhost:5000/v2/${repository}/tags/list | jq -r '(.name + ":" + .tags[])')
docker image pull localhost:5000/${image}
docker image tag localhost:5000/${image} <YOUR_HUB_PREFIX>/${image}
docker image push <YOUR_HUB_PREFIX>/${image}
# if you need some cleanup
docker image rm localhost:5000/${image} <YOUR_HUB_PREFIX>/${image}
done
done
Access to your registry machine via SSH, use docker login to login inside your Docker Hub account, add a tag to your images which points to Docker Hub docker tag my_own_registry.com/image:tag user/image:tag a then push that new tag using docker push user/image:tag.
#zigarn script automates this job.
Edit: You commented that your bandwith is bad, then you can access via ssh to your registry machine, save your image using docker save, then copy it to your machine and load it by docker load and finally push it to Docker Hub as explained above.
