I’m currently trying to install Docker on my old Raspberry Pi (3 Model B+) to host some personal projects. When I run docker run hello-world, I get:
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/library/hello-world/manifests/sha256:ec153840d1e635ac434fab5e377081f17e0e15afab27beb3f726c3265039cfff": dial tcp [2600:1f18:2148:bc00:eff:d3ae:b836:fa07]:443: connect: network is unreachable
My Internet connection does not support IPv6 at all, which would explain why this error occurs. But how do I force docker-pull to only use IPv4?
It will only try IPv6 if your computer has an address. Now the question is: if your network doesn’t support it, then why do you have an address?
They said thier internet connection didn’t support it, not their network.
You can lease ipv6 all day long but its not going to go anywhere if it can’t route to the internet.
Well where is the router getting the prefix from if their ISP doesn’t support it.
Some routers advertise a routable link local.
Link local adresses.
