Using yarn 0.21.3 in docker got warning: You don't appear to have an internet connection

[nickeljew]

Using official docker image node:6.10.0, and yarn 0.21.3 is included. The docker environment is running on CentOS7.

The network of the docker image is ok, coz both of 'agt-get xxx' and 'npm install -g xxx' work well.

However when running yarn, I got the following warning:

Step 7/9 : RUN yarn
---> Running in 7dbcdcfcb8b9
yarn install v0.21.3

After several failed tryouts, I completed the building successfully finally.
nodejs/docker-node#353

But I still wanna know if this warning is a bug or something else should be noticed?

I have pretty much the same problem. On different docker containers it works/fails, but not all the time, however there are containers where it happens 90% of the time, and on others 10%

Still present in 0.27.5

This should be resolved via 1.1.0 with the addition of DNS caching. Reopen if it persists with the latest version of Yarn please.

problem still present
Docker version 17.12.0-ce, build c97c6d6
Yarn version 1.5.1
Used Docker image: node:alpine

In my case even after several minutes (like 4 to 5 info lines) it would not get anything.
