Had this issue, but realized that it was a defective docker bridge or something. Restarting the daemon fixed it for me and the troubleshooting process was working back from DNS resolution, routing, etc from the pertinent host.

adding RUN echo -e "http://nl.alpinelinux.org/alpine/v3.5/main\nhttp://nl.alpinelinux.org/alpine/v3.5/community" > /etc/apk/repositories fixed my issue

https://github.com/gliderlabs/docker-alpine/issues/279 is a similar issue from the past.
I would like to report that we are also seeing timeouts updating against dl-cdn.alpinelinux.org. I have sidestepped the issue by adding references to one of the mirrors in our Dockerfile.

JoFAM commented 6 years ago

Had the same error trying to build an alpine-sdk docker using Docker Windows 10. Checked the status of the server, and the server was fine and reachable outside docker.

Restarting docker did the trick for me. Looking in the Docker log file it's clear that the DNS configuration was set incorrectly. So when seeing this error in a docker context, try to restart docker first.

azalio commented 6 years ago

In my situation was wrong /etc/resolv.conf file. Just check in a container ping dl-cdn.alpinelinux.org

syedsaadqamar commented 6 years ago

It's DNS issue you can solve it by using the following steps:

1) Find your DNS ip using below command nmcli dev show | grep 'IP4.DNS'

IP4.DNS[1]: 192.168.0.1

2) Create a file in the desktop which name is deamon.json and file has below data: { "dns": ["192.168.0.1", "8.8.8.8"] }

note: replace that ip "192.168.0.1" to your dns ip

3) Go that directory /etc/docker/ in your system and paste file deamon.json that you just created

4) Then restart your docker/your system, it will solve your issue.

drpreag commented 5 years ago

Seems your docker can not go out of host machine. Maybe this can help:

iptables -t nat -A POSTROUTING ! -o docker0 -s 172.17.0.0/16 -j MASQUERADE

adigunhammedolalekan commented 5 years ago

@GaudamThiyagarajan solution worked for me

s8sg commented 5 years ago

as pointed out by @azyata its can be a problem with the DNS settings

If you are performing apk add inside the container, below might be helpful

From docs.docker.com:

By default, a container inherits the DNS settings of the Docker daemon including the /etc/hosts and /etc/resolv.conf

  1. Try to ping

    ping dl-cdn.alpinelinux.org

    if it doesn't work

  2. Check DNS configuration in /etc/resolve.conf in host machine, try adding

    nameserver 8.8.8.8

    then perform ping 

    ping dl-cdn.alpinelinux.org

    if it works for you, then

  3. Restart the docker daemon 

    sudo systemctl restart docker

^ This solved the problem for me.

I solved it by creating a daemon.json file in /etc/docker/

and inserting:

{
  "bip": "192.168.1.5/24"
}

Restart docker and try again:

sudo systemctl daemon-reload
sudo systemctl restart docker

If I were to guess I'd say that docker bridge0 clash with the proxy in some way?

lucidyan commented 5 years ago

Dirty hack for resolving this without changing daemon settings:

RUN \
    # DNS problem workaround
    # https://github.com/gliderlabs/docker-alpine/issues/386
    printf "nameserver 8.8.8.8\nnameserver 9.9.9.9\nnameserver 1.1.1.1" > /etc/resolv.conf \
    \
    && apk add --no-cache bash

Notice that it only affect current layer, in other layers you should add this patch too if needed.

Also you can pass custom DNS server from the ARGs.

In the above case, obtaining via CDN was resolved by using the '--network=host' option at build time.

So I assumed that CDN wasn't down but something wrong about docker's network. I set the network as host by --network=host option and started to download. Hope this helps.

I got the above "IO ERROR WARNING" but I was able to curl(download) them from the host. So I assumed that CDN wasn't down but something wrong about docker's network.

I believe this happens when MTU in the container differs from the MTU on the host. What happens is that Fastly filters out need-to-frag ICMP packets so Path MTU is broken on fastly (and dl-cdn.alpinelinux.org).

I found that my corporate firewall wouldn't allow me to download via HTTP. Looking at https://mirrors.alpinelinux.org/ I found https://alpine.global.ssl.fastly.net/alpine to be my closest mirror. I replaced the default repositories by adding

RUN echo -e "https://alpine.global.ssl.fastly.net/alpine/v3.11/main\nhttps://alpine.global.ssl.fastly.net/alpine/v3.11/community\n" > /etc/apk/repositories

to switch to a mirror that supported HTTPS.

I tried most of the previous tips; however, only this one work for me.

  1. Check available networks

  2. Building image with --network=host

    docker image build ...... --network=host .

Doesn't work here. I guess it also depends on what routers/network the traffic passes through. --network=host works though.

I'm having this issue in the middle of the pandemic with alpine!

Fixed with setting the network to host: docker build . --network=host

atleta commented 4 years ago

I've also had this same issue, which I could solve by adding --network=host to my docker build call. But I found it pretty weird because I remembered that I never needed this, at least not until a recent OS (linux) upgrade, and it was still working without this option on for a colleague.

So after a bit of looking around, I found that my *docker0 and the `br-` interfaces were down, they did not have an IP address**. After restarting the docker daemon they came back up and everything started working again.

I've already noticed earlier that, since the upgrade, other virtual interfaces were brought down after a suspend (and not brought up on resume). This seems to be happening to docker too. So, if you experience this, check your docker network interfaces (e.g. with ifconfig or ip addr on linux) and if they are down, restart the docker daemon: (sudo systemctl restart docker on linux).

herrib commented 4 years ago

The issue can result from the by default configuration of firewalld (using nftables instead of iptables). I had experienced this issue until I performed the following workaround (https://github.com/docker/for-linux/issues/957). It consists of the modification of the /etc/firewalld/firewalld.conf.

Note 1: do not forget to declare the docker0 in the firewall rules.

Note 2: Docker and nftables

Fedora Wiki reads: _"Docker currently does not cooperate with the nftables backend. It currently side-steps firewalld by injecting its own rules in iptables ahead of firewalld's rules. However, with the nftables backend firewalld's rule will still be evaluated. Netfilter in the kernel will call iptables, then nftables for the same packet. This means firewalld/nftables is likely to drop the packet even if docker has iptables rules to ACCEPT."

and so does changing the folling parameter in the conf file /etc/firewalld/firewalld.conf to: FirewallBackend=iptables
