我有一个dockerfile
FROM alpine:3.7
RUN apk --no-cache add
php7
php7-fpm
php7-pdo
php7-pdo_mysql
php7-mcrypt
php7-mbstring
php7-xml
php7-openssl
php7-json
php7-phar
php7-zip
php7-dom
php7-session
php7-zlib &&
php7 -r "copy('http://getcomposer.org/installer', 'composer-setup.php');" &&
php7 composer-setup.php --install-dir=/usr/bin --filename=composer &&
php7 -r "unlink('composer-setup.php');" &&
ln -sf /usr/bin/php7 /usr/bin/php &&
ln -s /etc/php7/php.ini /etc/php7/conf.d/php.ini
RUN set -x
&& addgroup -g 82 -S www-data
&& adduser -u 82 -D -S -G www-data www-data
COPY . /src
ADD .env.example /src/.env
WORKDIR /src
RUN ["/bin/sh", "-c"," php artisan key:generate"]
RUN chmod -R 777 storage
CMD php artisan serve --host=0.0.0.0
在运行它时,我不断得到
Creating network "portal-modules_default" with the default driver
Building fingerprinting
> ERROR: Dockerfile parse error line 4: unknown instruction: PHP7
⚡️ portal-modules
错误:Dockerfile解析错误行4:未知指令:PHP7
关于如何解决该问题的任何提示?
我是否需要将&
放在某个地方以容纳命令?
答案 0 :(得分:3)
问题出在这里
RUN apk --no-cache add
php7
php7-fpm
php7-pdo
php7-pdo_mysql
php7-mcrypt
php7-mbstring
php7-xml
php7-openssl
php7-json
php7-phar
php7-zip
php7-dom
php7-session
php7-zlib &&
php7 -r "copy('http://getcomposer.org/installer', 'composer-setup.php');" &&
php7 composer-setup.php --install-dir=/usr/bin --filename=composer &&
php7 -r "unlink('composer-setup.php');" &&
ln -sf /usr/bin/php7 /usr/bin/php &&
ln -s /etc/php7/php.ini /etc/php7/conf.d/php.ini
如果要多行编写命令,请使用反斜杠(\
)符号:
RUN apk --no-cache add \
php7 \
php7-fpm \
php7-pdo \
php7-pdo_mysql \
php7-mcrypt \
php7-mbstring \
php7-xml \
php7-openssl \
php7-json \
php7-phar \
php7-zip \
php7-dom \
php7-session \
php7-zlib && \
php7 -r "copy('http://getcomposer.org/installer', 'composer-setup.php');" && \
php7 composer-setup.php --install-dir=/usr/bin --filename=composer && \
php7 -r "unlink('composer-setup.php');" && \
ln -sf /usr/bin/php7 /usr/bin/php && \
ln -s /etc/php7/php.ini /etc/php7/conf.d/php.ini
在断行时向每行添加反斜杠。
