我尝试在docker compose上运行php artisan migrate，但在我的mysql容器中出现此错误：

sh: php: command not found

docker-compose.yml

mysql映像只包含数据库。entrypoint:设置说“运行这个命令而不是容器正常运行的命令，甚至忽略它的默认设置”。由于您已经将entrypoint:附加到database:，因此您尝试运行php artisan migrate而不是运行MySQL，并且您在仅数据库映像中运行它。
迁移步骤需要附加到应用程序容器，而不是数据库容器。我倾向于将其编写为一个 * 入口点 Package 器脚本 *，一个编译到镜像中的脚本，它作为镜像的默认ENTRYPOINT运行，但接受普通的CMD作为实际的主容器进程。最简单的形式如下

#!/bin/sh
# entrypoint.sh
# run migrations
php artisan migrate
# run the main container `CMD` (or an execution-time override)
exec "$@"

这里的一个复杂之处在于，在Dockerfile中设置ENTRYPOINT也会重置CMD，而php:apache图像带有默认的CMD。如果你看一下Docker Hub php image page，然后点击“Dockerfile链接”页面，你可以找到官方的Dockerfile for php:8.0-apache。如果您查看该文件的结尾，它同时具有ENTRYPOINT和CMD，因此您需要在设置中复制这两个文件。

#!/bin/sh
# entrypoint.sh
...
# run the main container CMD, via the original ENTRYPOINT
exec docker-php-entrypoint "$@"
#    ^^^^^^^^^^^^^^^^^^^^^
#    this is the base image's ENTRYPOINT

# Dockerfile
...
WORKDIR /var/www
# copy the application source and supporting scripts into the image
COPY ./ ./
# set the entrypoint to our wrapper script, and repeat the base
# image's command
ENTRYPOINT ["./entrypoint.sh"]
CMD ["apache2-foreground"]
#   ^^^^^^^^^^^^^^^^^^^^^^
#   this is the base image's CMD

现在，在Compose设置中，您不需要为这些容器中的任何一个设置command:或entrypoint:，也不需要将应用程序代码装入容器;所有这些细节都已经设置在图像中。
