I had initially thought this was the same as: Kubernetes imagePullSecrets not working; getting "image not found"
However, even disabling authentication (to avoid the need for secrets) still produces the same error.
So, Kubernetes trying to pull images from Nexus Docker registry keeps producing the kubernetes error:
"Failed to pull image "nexus.mydomain.co.uk/nginx": Error: image nginx:latest not found"
This is also reflected in the Nexus logs:
2016-06-22 14:51:26,929+0000 WARN [qtp556619582-227] docker org.sonatype.nexus.repository.docker.internal.V1Handlers - Error: GET /v1/repositories/nginx/images: 404 - org.sonatype.nexus.repository.docker.internal.V1Exception$ImagesNotFound: images not found
I can't get onto the kube boxes to try a pull, however, when I run "docker pull" from my mac command line all is well and good.

I have created some images in the Gitlab Container Registry. I am unable to pull them using docker on my local system. The login command succeeds but when I type the following command:
docker pull reg-gitlab-project.company.com/services/palimited/integrationservices/springbootproject/springbootproject:latest
I am getting the following error
Error response from daemon: Head "https://reg-gitlab-project.company.com/v2/services/palimited/integrationservices/springbootproject/springbootproject/manifests/latest": denied: access forbidden
I am unable to figure out why this error is occuring? Can anyone guide me.
You need to authenticate with the container registry at reg-gitlab-project.company.com before issuing a docker pull command.
See, GitLab Docs: Authenticate with the Container Registry.
I am trying to deploy a Docker Image to Heroku. The image is external and hosted on https://quay.io/repository/mldb/mldb?tab=info.
To run the image, I have created an app on Heroku. The app is called still-dawn-24875.
I log into the heroku container.
Now I am trying to pull the docker image from repository. I am running the following command -
heroku container:pull --verbose --app=still-dawn-24875 mldb
The command is throwing following error -
=== Pulling mldb as registry.heroku.com/still-dawn-24875/mldb
heroku-container-registry docker [ 'pull', 'registry.heroku.com/still-dawn-24875/mldb' ] +0ms

I have tried this with another repository on Docker Hub as well. It gives me the same error.
Any idea on what could be the issue and how we can resolve this?
Working on getting development environment setup in Minikube and ran across an issue pulling images from the https://quay.io/v2/ registry.
I have ran the command:
eval $(minikube docker-env) .
Which allows me to build my local Dockerfile in Minikube and it does a great job with that and deployments work great with local images.
I then used helm to install
helm install stable/mssql-linux .
Which worked fine and its image points to this microsoft/mssql-server-linux:2017-CU3 HERE
I am also working with redis-ha and installed like so:
helm install stable/redis-ha --set="rbac.create=false"
The rbac.create=false seems to allow it to install in Minikube without causing all sorts of issues. However, despite creating deployments and services...the deployments ultimately fail because it cant pull the image.
I get the following error:
Failed to pull image "quay.io/smile/redis:4.0.8r0": rpc error: code = Unknown desc = Error response from daemon: Get https://quay.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
The deployments point to this registry image: quay.io/smile/redis:4.0.8r0
I have changed my DNS pretty much everywhere I could to point to 8.8.8.8 as it seems like it cant resolve the URL. It could also just be that I need to add the registry someplace? I kind of feel that its registry specific since Minikube docker daemon appears to be able to pull from docker hub but not quay.io.
If I use a terminal that is not running eval $(minikube docker-env) and use the docker daemon on my host computer I can pull the quay.io/smile/redis:4.0.8r0 image just fine...ssh into minikube and try and it cant pull.
Minikube version
minikube version: v0.25.0
Docker for Mac
Version 17.12.0-ce-mac55 (23011)
as it seems like it cant resolve the URL
What lead you to believe that, when the error clearly states that it has a Client.Timeout exceeded while awaiting headers? It resolved the registry to an IP address, and even apparently opened a network connection to what it thinks is the registry's IP and port. But after that, the networking stack in minikube did not, in fact, allow the traffic out. Observe that the error wasn't DNS, and it wasn't connection refused, it was connection timed out. That is almost always a firewall-esque behavior.
That smells very, very much like a corporate HTTP proxy, since your machine can interact with the Internet but minikube cannot.
There are a ton of troubleshooting steps one could go through, however, if you are interested in a very quick win, you can, from your working host computer, run docker save quay.io/smile/redis:4.0.8r0 | ssh-into-minikube "docker load" and treat minikube as if it were airgapped.
I dont know what the underlying reason was...perhaps Minikube just being fragile but ended up:
Removing minikube
rm -rf ~/.minikube
Running start again
minikube start --vm-driver=hyperkit
Reran init helm init
Now everything is pulling as it should....
I'm new to Docker so I don't even know where to look. Here are the instructions:
Next, pull a base image that’s compatible with the evaluation build, re-tag it and to a test-run:
docker pull microsoft/windowsservercore:10.0.14393.321
docker tag microsoft/windowsservercore:10.0.14393.321 microsoft/windowsservercore
docker run microsoft/windowsservercore hostname
69c7de26ea48
And this is the error I get on the docker run step:
docker: Error response from daemon: container

I'm trying to check the installation docker pull hello-world
But getting the following error:
Pulling repository hello-world
Get https://index.docker.io/v1/repositories/library/hello-world/images: remote error: access denied
I have CentOS 6.5
Docker version 1.7.1, build 786b29d/1.7.1
I'm in a corporate network but curl https://index.docker.io/v1/repositories/library/hello-world/images forks fine.
What might be the issue?
Thanks in advance!
I got this error while I was trying to pull mongodb image instead of mongo.
So make sure image name is correct. The very same error message happens on both run and pull commands.
Had the same problem & error on the host working via proxy.
In essence - if you are behind an HTTP proxy server, you will need to add proxy configuration in the Docker systemd service file.
https://docs.docker.com/engine/admin/systemd/
(See at "HTTP proxy" section).
This helped me.
Did you add your user in docker group
https://docs.docker.com/engine/installation/linux/centos/#/create-a-docker-group
Otherwise, you should execute docker command with sudo before
docker pull hello-world
