#Error response from daemon: You cannot remove a running container

macOS
$ docker rm 2acdf0e00448
Error response from daemon: You cannot remove a running container 2acdf0e00448f2aa3ae57e5aa690065fb5bb1a139155f0181404435d7b515c72. Stop the container before attempting removal or force remove

stopするか、中でexitする。

docker/ubuntu
# exit
exit
$

exit表示してくれなくても、コマンドプロンプト変わるからわかるんだけど。

macOS
$ docker rmi 8144c217aa50 

今度はエラーがでるんじゃなくて、10分経っても、うんともすんとも変わらない。
別のshellでpsすると、やっぱりまだ動いているっぽい。

macOS
$ ps -ax

どうしよう。今日は、待ち時間が多い。
コマンドを待っている間には、記事書いている。
その前のエラーのやつと、この記事の書きかけ。
何もせずに待つことはない。
