検索しても見つからなかったのでメモ。
Cannot create container for service web: failed to copy files: failed to open target
→ .dockerignoreで定義したディレクトリをホストでディレクトリ毎消したのが原因かも。
“ENOSPC: no space left on device
→ 一般的には、ホストのディスク容量かinode不足が原因だが。。。
事象1
rubocopやerdでも、全てダメな感じ。

コンソールに接続して、実行すると行ける。

ホストのディスク容量かinode不足だと出るらしいが、両方とも問題なかった。
全消ししたら、動くようになった。
何度も調整してbuildしたから、増え過ぎたのかもね。
