docker build failing with wget: unable to resolve host address

[sibman]

I have tried to build the docker-rust-nightly image and all of the images failing with similar error. Here is my docker information: docker version Client: Version: 19.03.6 API version: 1.40 Go version: go1.12.17 Git commit: 369ce74a3c Built: Fri Feb 28 23:45:43 2020 OS/Arch: linux/amd64 Experimental: false

Here I'm attaching couple of build logs.

This seems like a networking issue on your end, or maybe a transient DNS issue. static.rust-lang.org definitely exists.

I could execute the commands which listed in docker file with out any issues from the host os, but when I attaching to container terminal of buildpack-deps:stretch image and trying to run wget command from a container I'm getting identical results as I presented in logs. Here I'm attaching the steps to replicate the issue.

docker run -it buildpack-deps:stretch /bin/bash root@27e7b911e0d3:/# wget https://static.rust-lang.org/rustup/dist/x86_64-unknown-linux-gnu/rustup-init --2020-04-10 14:04:19-- https://static.rust-lang.org/rustup/dist/x86_64-unknown-linux-gnu/rustup-init Resolving static.rust-lang.org (static.rust-lang.org)... failed: Temporary failure in name resolution. wget: unable to resolve host address 'static.rust-lang.org' root@27e7b911e0d3:/#

That looks like an issue with Docker rather than the nightly rust image, so I'd look in that direction.
