lookup registry-1.docker.io: no such host

I have docker daemon running on my Ubuntu 16.4 server

my server details:

No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 17.04 Release: 17.04 Codename: zesty

I'm receiving the following error:

aa@aaa-VirtualBox:/etc/default$ docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io: no such host.
See 'docker run --help'.

I have set the http_proxy and the https_proxy beacuse i'm behind a corp proxy/firewall

Any clues how I can fix this issue?

I "fixed" it by using another image's tag. In my case I got the same error for java:11-jre, but when I use java:11, everything is work fine. So, just try another tag

For windows going to resources > Network and changing DNS to 8.8.8.8 did the trick. Also make sure to restart after changing. enter image description here

In my case, I had a bad config entry in /etc/nsswitch.conf that prevented docker from resolving container registries.

In /etc/nsswitch.conf, my hosts line looked like this:

hosts:      files myhostname

After changing the hosts property to default value, everything worked.

# default value for hosts
hosts:      files myhostname mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns

After changing the /etc/nsswitch.conf file, make sure to restart systemd-resolved.service.

Had a similar problem in Docker Desktop for windows, running on top of WSL2 behind a corporate proxy.

After trying the above solutions without no success, the problem was resolved by adding *.docker.com to the Proxy bypass.

I tried many of the above answers, but to no avail.

Finally, this approach worked for me:

docker logout
docker login

I have no idea why though.

Go to Docker Settings -> Proxies -> Manual proxy configuration.

Set the proxy details in the input and apply.

Restart the docker. This will fix the issue.

I solve the error changing DNS server by 8.8.8.8 - Ubuntu 18.04.3 LTS

1- Open the Ubuntu System Settings and Navigate to Network

enter image description here

2- Click the on the setting button next to the Network name in the list to which you are connected.

3- New Window will open with a lot number of tabs, with one of them with the label of “IPv4”.

enter image description here

4- Upon opening the “IPv4” Tab you will find a Field of “DNS”. Here you can write the DNS server

enter image description here

If you want to use more than one DNS, then you can enter and separate them with a comma.

Things you can try:

a) Add nameserver 8.8.8.8

Method #1

docker-machine ssh default
sudo vi /etc/resolv.conf
//change nameserver to 8.8.8.8

Then restart the server using 

service docker restart

Note: If you don't have docker-machine installed, you can follow instructions here to install it. It comes with Windows and Mac but is available for install on Linux manually.

Method #2

Edit /etc/docker/daemon.json Or "provide a JSON configuration in the preference panel" with the following information:

{ "dns" : [ "8.8.8.8", "8.8.4.4" ]}

Then restart the server using 

service docker restart

b) Setup Proxy

Method #1

Edit your proxy configuration as Tarun Lalwani suggested.

Edit /etc/default/docker and add:

export http_proxy='http://username:password@proxy-host:proxy-port'
export https_proxy='https://username:password@proxy-host:proxy-port'

Then restart the server using 

service docker restart

Method #2

Source: https://github.com/moby/moby/issues/32270#issuecomment-340709035

  1. Create a systemd drop-in directory for the docker service:

    mkdir -p /etc/systemd/system/docker.service.d
# For HTTP Proxy:
vim /etc/systemd/system/docker.service.d/http-proxy.conf
# For HTTPS Proxy:
vim /etc/systemd/system/docker.service.d/https-proxy.conf

  2. Then add below content with proxy settings with it (Change to "HTTPS" for https)

    [Service]
Environment="HTTP_PROXY=http://<allowed_proxy_ipv4_address>:<proxy_port_num>/"
[Service]

  3. sudo systemctl daemon-reload

  4. sudo systemctl restart docker
  5. Verify that the configuration has been loaded: systemctl show --property=Environment docker

c) Reinstall Docker

Unfortunately the last resort, could work. Check out these github pages for more suggestions:

For me, setting up the proxy using the systemctl method was the only thing that worked.

You need to set the proxy for Docker daemon also using environment variable. Docker run is also doing docker pull since the image doesn't exists. In your case the proxy is only applied to the docker run command, which delegates to the docker daemon which is running without proxy.

Create a file named /etc/systemd/system/docker.service.d/10_docker_proxy.conf with below content

[Service]
Environment=HTTP_PROXY=http://1.1.1.1:111
Environment=HTTPS_PROXY=http://1.1.1.1:111

Make sure to update the proxy as per the ones you have 1.1.1.1:111 is just an example

Then execute below commands to restart docker

sudo systemctl daemon-reload
sudo systemctl restart docker

Now use your docker run command and it should work
