啟動容器后，我嘗試使用attach它，但沒有得到回應；只是閃爍的游標
我做 docker-compose up -d
[ ] Running 2/2
? Container mariadb Started 2.2s
? Container backend Started
然后 docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
85041e7609d4 backend "docker-php-entrypoi…" 10 seconds ago Up 7 seconds 0.0.0.0:8000->8000/tcp, 9000/tcp backend
412c03f5b410 mariadb "docker-entrypoint.s…" 11 seconds ago Up Less than a second 0.0.0.0:3306->3306/tcp mariadb
然后 docker attach 85041e7609d4
試過docker logs 85041e7609d4但那里什么都沒有
如果我docker run -ti --rm backend bash可以作業，但這沒有使用docker-compose

uj5u.com熱心網友回復：
您已附加到正在運行的容器
tail -f /dev/null
該命令沒有輸出，也不接受任何輸入。/dev/null 不會有任何結果。
如果你需要一個外殼，你應該執行那個外殼，例如
docker-compose exec backend bash
如果你想要日志，你運行的命令應該是你的應用程式，你的應用程式應該輸出日志。
