Dockerでbuildを実行したら、名前解決が出来ずにエラー

Last updated at Posted at 2020-05-31

Ubuntu 20.04で
$ docker build .

を実行したら、以下のようなエラーが複数回発生してタイムアウトした。

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError(': Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/pipenv/

$ sudo vi /etc/default/docker
でDockerの設定ファイルを開き

DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
のコメントアウトを外した後

$ sudo service docker restart
でエラーが解消された。
