我的问题是正如标题所述,如果我不重建图像,无论我对文件进行的任何更改,浏览器都不会显示。我用sh来查看更改是否确实存在于容器内,是的,他们有。
我正在使用docker-compose:
version: '3.7'
services:
postgres:
image: postgres:alpine
restart: always
environment:
POSTGRES_DB: db
POSTGRES_USER: root
POSTGRES_PASSWORD: pw123
php:
build:
context: .
dockerfile: ./docker/php/Dockerfile
restart: always
env_file:
- ./app/.env
user: 1000:1000
nginx:
image: nginx:1.15.3-alpine
restart: always
volumes:
- ./app:/usr/src/app
- ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro
ports:
- 80:80
depends_on:
- php
这是我的php服务dockerfile:
# ./docker/php/Dockerfile
FROM php:7-fpm-alpine
RUN apk update && apk add build-base
RUN apk add postgresql postgresql-dev \
&& docker-php-ext-configure pgsql -with-pgsql=/usr/local/pgsql \
&& docker-php-ext-install pdo pdo_pgsql pgsql
#RUN docker-php-ext-install opcache
#RUN curl -o /tmp/composer-setup.php https://getcomposer.org/installer \
#&& curl -o /tmp/composer-setup.sig https://composer.github.io/installer.sig \
# Make sure we're installing what we think we're installing!
#&& php -r "if (hash('SHA384', file_get_contents('/tmp/composer-setup.php')) !== trim(file_get_contents('/tmp/composer-setup.sig'))) { unlink('/tmp/composer-setup.php'); echo 'Invalid installer' . PHP_EOL; exit(1); }" \
#&& php /tmp/composer-setup.php --no-ansi --install-dir=/usr/local/bin --filename=composer --snapshot \
#&& rm -f /tmp/composer-setup.*
COPY docker/php/opcache.ini /usr/local/etc/php/conf.d/opcache.ini
COPY app /usr/src/app
WORKDIR /usr/src/app
#install usermod
#RUN echo http://dl-2.alpinelinux.org/alpine/edge/community/ >> /etc/apk/repositories
#RUN apk --no-cache add shadow && usermod -u 1000 www-data
#RUN composer install --no-plugins --no-scripts
#ENV PATH="~/.composer/vendor/bin:./vendor/bin:${PATH}"
#RUN usermod -u 1000 www-data
#RUN chown -R www-data:www-data /var/cache
#RUN chown -R www-data:www-data /var/log
EXPOSE 9000
CMD ["php-fpm","--nodaemonize"]
对于docker来说可能不是问题,因为我对Web服务器(nginx),php fpm,opcache有基本的了解,其中之一可能会引起问题,所以我将发布其他conf文件:
nginx的default.conf:
# ./docker/nginx/default.conf
server {
server_name ~.*;
location / {
root /usr/src/app;
try_files $uri /index.php$is_args$args;
}
location ~ ^/index\.php(/|$) {
client_max_body_size 50m;
fastcgi_pass php:9000;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/src/app/public/index.php;
}
error_log /dev/stderr debug;
access_log /dev/stdout;
}
opcache.ini:
[opcache]
opcache.enable=1
; 0 means it will check on every request
; 0 is irrelevant if opcache.validate_timestamps=0 which is desirable in production
opcache.revalidate_freq=0
opcache.validate_timestamps=1
opcache.max_accelerated_files=10000
opcache.memory_consumption=192
opcache.max_wasted_percentage=10
opcache.interned_strings_buffer=16
opcache.fast_shutdown=1
答案 0 :(得分:1)
您正在将应用程序卷映射到NGINX,但没有从那里提供文件。您default.conf中的这一行fastcgi_pass PHP:9000
表示所有流量都(正确)重定向到了PHP容器。
由于您是从PHP容器中提供文件,因此应在该位置映射卷而不是复制卷(COPY应用/usr/src/app
)。
您可以从php Dockerfile中删除(COPY ...)行,然后尝试以下docker-compose
:
version: '3.7'
services:
postgres:
image: postgres:alpine
restart: always
environment:
POSTGRES_DB: db
POSTGRES_USER: root
POSTGRES_PASSWORD: pw123
php:
build:
context: .
dockerfile: ./docker/php/Dockerfile
restart: always
env_file:
- ./app/.env
volumes:
- ./app:/usr/src/app
user: 1000:1000
nginx:
image: nginx:1.15.3-alpine
restart: always
volumes:
- ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro
ports:
- 80:80
