我有这个简单的shell脚本来启动Docker中的laravel应用程序：

#!/bin/sh

set -ex
# generate the key if it does not already exist
case `grep APP_KEY .env | sed -e 's/APP_KEY=\s*//'` in
    'base64:'*)
        echo "artisan key already exists...";;
    *)
        echo "generating artisan key..."
        php artisan key:generate;;
esac
# create or update database
echo "create or update database..."
php artisan migrate --force
echo "starting server"
exec "/usr/local/bin/php artisan serve --host=0.0.0.0"

字符串
行php artisan migrate工作正常，所以php在PATH中，但行exec "/usr/local/bin/php artisan serve --host=0.0.0.0"（w/或w/o/usr/local/bin路径）显示：

/var/www/docker_init.sh: exec: line 16: /usr/local/bin/php artisan serve --host=0.0.0.0: not found

型
Docker文件包含：

FROM php:8.2-fpm-alpine

# Arguments defined in docker-compose.yml
ARG user=fcms
ARG uid=1000

# install helper for installing php extensions
ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
# install php extensions
RUN chmod +x /usr/local/bin/install-php-extensions && \
   install-php-extensions @composer pdo_mysql exif pcntl gd imagick

# Set working directory
WORKDIR /var/www

# Create system user to run Composer and Artisan Commands
RUN addgroup -S $user && \
    adduser -G $user -G www-data -G root -u $uid -h /home/$user -S $user && \
    mkdir -p /home/$user/.composer && \
    chown -R $user:$user /home/$user
# Copy the fcms code
COPY --chown=$user:www-data . .
RUN \
    # move the right init file (which execs php artisan serve at the end)
    mv docker/apache/init.artisan.sh ./docker_init.sh && \
    # clean unused folders and blocking files
    rm -rf docker vendor composer.lock .git && \
    # Install everything
    composer install --no-dev

# Set user
USER $user

HEALTHCHECK --interval=5m --timeout=3s --start-period=10s \
  CMD curl -f http://localhost/ || exit 1

CMD ["/var/www/docker_init.sh"]

其中docker_init.sh是上面的脚本。最后一件事，运行：

docker run -it fcms.artisan php artisan serve --host=0.0.0.0

型
效果很好。
我不明白“执行”有什么不对...
