Docker - Unable to pull images - certificate issues? - docker

I have installed Ubuntu on Oracle VirtualBox on my Corporate Machine which is running Windows 7. On Ubuntu , I have the latest docker installed. I am behind corporate proxy. I guess, I have set up right HTTP_PROXY params.
However, when I try running a simple command , I get the below issue.
tma0si3UBUNTU:~$ sudo docker run hello-world Unable to find image
'hello-world' locally Pulling repository hello-world af340544ed62:
Error pulling image (latest) from hello-world, endpoint:
https://registry-1.docker.io/v1/,x50af340544ed62:
Error pulling image (latest) from hello-world, x509: certificate signed by unknown authority 2015/09/10 10:26:37 Could not find repository on any of the indexed registries.
Any help ?

Docker pull giving connection reset by peer error

I have installed Docker on Ubuntu machine. I have problem with docker pull command, I am getting connection reset by peer error.
root#machine1:~# docker pull ubuntu
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/: read tcp 10.80.64.126:51404->54.152.209.167:443: read: connection reset by peer
command : docker images worked and gave empty result as no image is downloaded on docker host. But as this command is working, shows docker installed successfully.

Unable to pull ubuntu image using docker on windows host

I have installed docker on windows 10.
Docker version:
Docker version 17.09.0-ce, build afdb6d4
I tried to pull latest ubuntu and ubuntu:16.04 using the bellow two commands
docker pull ubuntu
docker pull ubuntu:16.04
But I am getting the below error.
docker pull ubuntu
Using default tag: latest
latest: Pulling from library/ubuntu
no matching manifest for windows/amd64 in the manifest list entries
So is there any way to fix this issue?
You can't run linux images with a windows daemon.
If you are running Docker for Windows, it gives you the ability to switch between running a Windows Docker daemon and a Linux Docker daemon inside a hyper-v VM.
To run Linux workloads, make sure you have chosen "Switch to Linux Containers" in the Docker for Windows whale icon menu.
please follow the Docker tutorial here
In this case the problem is it requires adding the --experimental flag when starting dockerd.exe.

Docker - x509:certificate signed by unknown authority error in windows 7

I have installed Docker toolbox on windows 7 64 bit. When I try to run docker run hello-world command to verify my installation I get following error:
$ docker run hello-world
Unable to find image 'hello-world:latest' locally
C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: Get http
s://registry-1.docker.io/v2/: x509: certificate signed by unknown authority.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
I am behind company firewall and also I have added proxy info in Docker Toolbox\start.sh file:
export HTTP_PROXY="ip address:port"
export HTTPS_PROXY="ip address:port"
below line export PATH="/c/Program Files/Docker Toolbox:$PATH"
I am getting same error **x509: certificate signed by unknown authority** when I run docker-compose command.
How I can resolve this error.
Thanks in advance.
After removing proxy docker works fine and I am able to pull images.

Any advice on how to proceed?
Your docker engine is trying to contact the registry and having some sort of CDN, firewall, or corporate proxy issue trying to have a proper "conversation" with the registry. It's pretty similar to being on hotel or public WiFi that has a "walled garden" that hasn't been processed through yet.
Unless you have a persistent network issue, it could be temporal, and as someone else suggested a docker pull hello-world:latest may work. If you have a corporate proxy, you may have to make sure the Docker toolbox/Docker for Windows configuration has this proxy configured properly to have network access.

Unable to pull docker image, getting 'remote error: access denied'

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
