Unable to find image 'hello-world:latest' locally

[yogeshagr]

Description of problem:

I have installed docker in my machine following the official installation steps for ubuntu. At the verification steps it fails.

When I run the command: docker run hello-world it throws following error message:

Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Error while pulling image: Get https://index.docker.io/v1/repositories/library/hello-world/images: dial tcp 52.0.10.162:443: connection refused

My machine is behind the corporate proxy. So I tried to download the image manually using wget command, as follows:

wget https://index.docker.io/v1/repositories/library/hello-world/images

But I still don't know at which location I should place this image. Can we place this images file manually at the docker configuration folder ?

Below are the docker details for my machine.

If someone knows what is the problem please help ?

try this
https://github.com/docker/docker/blob/master/docs/reference/commandline/import.md

Could it help ?

If you behind firewall, I think you need configure proxy to make it work

[yogeshagr]

Thanks @HackToday. I specified proxy settings in /etc/default/docker file, and restarted the service. Then I am able to run hello-world image and do further tasks.

[quiet-ranger]

Could someone please tell us what is the name of the configuration file where a proxy can be set? The directory structure is different on Windows but I hope the configuration file will be the same. Thanks.

[yogeshagr]

For linux it is "/etc/default/docker" file.

I think you can specify this when creating the machine, see docker-archive/toolbox#102 (comment):

docker-machine create -d virtualbox \
    --engine-env HTTP_PROXY=http://example.com:8080 \
    --engine-env HTTPS_PROXY=https://example.com:8080 \
    --engine-env NO_PROXY=example2.com \
    default

[prayagupa]

yep, if you cat /etc/default/docker, you see

# Docker Upstart and SysVinit configuration file

#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
#   Please see the documentation for "systemd drop-ins":
#   https://docs.docker.com/engine/articles/systemd/
#

# Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"

# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

# If you need Docker to use an HTTP proxy, it can also be specified here.
export http_proxy="http://127.0.0.1:3128/"

# This is also a handy place to tweak where Docker's temporary files go.
#export TMPDIR="/mnt/bigdrive/docker-tmp"

For the next ones having problems with an HTTP_PROXY on a systemd host, simply follow these instructions:

https://docs.docker.com/engine/admin/systemd/#/http-proxy

works!

How to get this working , when user is behind proxy and don't know his proxy setting?

[RupenAnjaria]

How to set this for Windows 7?

[thaJeztah]

@RupenAnjaria On Windows 7 you're probably running docker toolbox, see here for the setting proxies; https://docs.docker.com/toolbox/faqs/troubleshoot/#/http-proxies-and-connectivity-errors
