[gentoo-user] Docker installation issues

[gentoo-user] Docker installation issues

[Mansour Al Akeel]

[-- Attachment #1: Type: text/plain, Size: 8996 bytes --]

I am using Openrc

This was my initial /etc/conf.d/docker
DOCKER_OPTS="--storage-driver overlay2 --data-root /srv/var/lib/docker"

when I try:

$ docker pull hello-world

Error response from daemon: Get "https://registry-1.docker.io/v2/":
net/http: request canceled while waiting for connection (Client.Timeout
exceeded while awaiting headers)

Trying to troubleshoot:

Looking at resolv.conf

localhost /home/mansour # cat /etc/resolv.conf
# Generated by dhcpcd from wlp3s0.dhcp
# /etc/resolv.conf.head can replace this line
domain Home
nameserver 192.168.1.1
# /etc/resolv.conf.tail can replace this line

So, I added the following to my /etc/dhcpcd.conf
static domain_name_servers=8.8.8.8 8.8.4.4 192.168.1.1

And restarted dhcpcd:

localhost /home/mansour # cat /etc/resolv.conf
# Generated by dhcpcd from wlp3s0.dhcp
# /etc/resolv.conf.head can replace this line
domain Home
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 192.168.1.1
# /etc/resolv.conf.tail can replace this line


docker.log still shows the same error:

I am not able to login with "docker login"

Where do I look further for additional troubleshooting hints? Google didn't
help a lot.

Thank you.

Hello,
my first step would be checking if there is some inherent network
problem reaching registry-1.docker.io/v2, e.g. via
curl -v https://registry-1.docker.io/v2/

If that runs successfully, you could try if there is an MTU problem. I
remember that I had to set MTU to 1450 in some virtualized environment,
otherwise docker would not run correctly, i.e. I  had in
/etc/conf.d/docer
DOCKER_OPTS="--mtu=1450"

Hope that gives you an idea what to look for.

If both does not help, there is wireshark, to watch your network, very
low-level, but might give some hints.

Andreas,

Thank you very much. In fact I didn't go that deep yet, and not sure if I
should. I just found that the url is not accessible even from a browser.
Googling a bit, tells me there is no clear URL for docker-registry and
possibly this one is outdated. I will continue looking around to confirm
what the current default repo should be. If you have any suggestions,
please let me know.

You have a a strange DNS resolution. The IP address 34.227.211.243
seems wrong. Here is what I see when I look at the DNS records:

I am not sure
Not sure where you get the wrong IP from, but it is a DNS issue.
