docker - docker compose将保留旧卷，现在无法清除它们

docker compose将保留旧卷，现在无法清除它们

我试图将当前目录挂载到容器中，

并多次更改其挂载名称，

像crawler-> data-crowler-> ... root
但是，一旦我挂载它，即使我更改了mount volume name，它也将保留在容器中

有趣的是，我从未使用USER seluser做任何事情，

但是您可以看到文件夹的所有者是seluser
那怎么会发生呢？

Dockerfile的结尾

EXPOSE 4444
WORKDIR  /lazy-bird
CMD ["/usr/bin/supervisord"]

docker-compose.yml

web:
  build: .
  volumes:
      - .:/lazy-bird

根目录

drwxrwxr-x   6 seluser seluser 4.0K Jun 10 02:39 crawler/
drwxrwxr-x   6 seluser seluser 4.0K Jun 10 02:39 data-crowler/
drwxrwxr-x   6 seluser seluser 4.0K Jun 10 02:39 lazy-bird/

您需要通过以下方式跟踪Dockerfiles中的整个步骤，然后您应该知道USER seluser涉及镜像的时间
