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.

[GaudamThiyagarajan]

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

[JPWKU]

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.

Hello,

Is there any fix available for this? I'm getting same error especially in APAC region.

@prawen 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 before your $ apk add --no-cache bash

[JoFAM]

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.

[prawen]

After trying both the workarounds I'm still getting below error.

If you do not know what the reason is, then it is probably DNS

• 8.8.8.8 cannot resolve dl-cdn.alpinelinux.org
• ns1.alpinelinux.org can resolve dl-cdn.alpinelinux.org
• dl-cdn.alpinelinux.org is CNAME for global.prod.fastly.net
• ns1.alpinelinux.org cannot resolve global.prod.fastly.net
• 8.8.8.8 can resolve global.prod.fastly.net

[helgeolav]

It seems to be an issue with wget (or any other tool fetching data) not sending host header when requesting resources.

[neclimdul]

not sure what you mean. Here's the wireshark of apk requesting the APKINDEX.tar.gz

[jingax10]

I hit the same error. Any more update?

RUN echo -e "http://nl.alpinelinux.org/alpine/v3.5/main\nhttp://nl.alpinelinux.org/alpine/v3.5/community" > /etc/apk/repositoriesdoes not work for me :-(

[neuralsandwich]

Running the echo command and it didn't seem to help. I ended up just restarting my laptop and that seemed to work.

[amarjeet27]

Any others suggestions on working around this issue?

[us108y]

Not working for me any updates on this ,,

This is annoying

[azalio]

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

[syedsaadqamar]

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]

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

[deepsnitk]

Please use docker run -e OR docker build --build-arg to pass http_proxy env variable required for apk package manager

[adigunhammedolalekan]

@GaudamThiyagarajan solution worked for me

[s8sg]

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 am also getting below error:

I'm behind a proxy and I experienced a similar error:

fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/main/x86_64/APKINDEX.tar.gz
ERROR: http://dl-cdn.alpinelinux.org/alpine/v3.10/main: temporary error (try again later)

WARNING: Ignoring APKINDEX.d8b2a6f4.tar.gz: No such file or directory
2 errors; 15 distinct packages available

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

sudo nano /etc/docker/daemon.json

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]

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.

docker build -t sample --network=host .

I got the above "unsatisfiable constraints" 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 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).
