[MrMic]

Hi,

When i try to buils an image for a rust App I always got this error:

0.544 Updating crates.io index 0.548 warning: spurious network error (3 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io) 1.940 warning: spurious network error (2 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io) 5.441 warning: spurious network error (1 tries remaining): [6] Couldn't resolve host name (Could not resolve host: index.crates.io) 11.94 error: failed to getchronoas a dependency of packagerust-web-dev v1.0.0 (/app)11.94 11.94 Caused by: 11.94 failed to query replaced source registrycrates-io11.94 11.94 Caused by: 11.94 download of config.json failed 11.94 11.94 Caused by: 11.94 failed to download fromhttps://index.crates.io/config.json`

`

Any idea to solve this?
I am stuck and have not find any fix that works on internet.

Could not resolve host: index.crates.io

Cargo is trying to resolve the domain name index.crates.io and can't. This is a DNS issue, possibly an issue with your local network or local machine. The domain name currently resolves from where I am.

Not at all! Everything is working perfectly fine on my host.
The issue is inside the container ... and indeed it is a domain
name issue when I create the image from a rust app.
What is weird is that when I run a rust container alone from CLI and
log into it, I can download what I want.

The issue tracker is for problems or features in Rust or the tools we distribute. It sounds like you need support with using Cargo in your Docker setup, so one of these places would be a better place to get help: https://www.rust-lang.org/community
