wordpress:
build: .
links:
- mysql
- composer
volumes:
- wp-content/plugins/:/var/www/html/wp-content/plugins
- wp-content/themes/:/var/www/html/wp-content/themes
environment:
- WORDPRESS_DB_PASSWORD=__WORDPRESS_DB_PASSWORD__
- WORDPRESS_DB_NAME=__WORDPRESS_DB_NAME__
# - WORDPRESS_DB_USER=__WORDPRESS_DB_USER__
ports:
- "9888:80"
mysql:
image: mysql:5.7
environment:
- MYSQL_ROOT_PASSWORD=__WORDPRESS_DB_PASSWORD__
- MYSQL_DATABASE=__WORDPRESS_DB_NAME__
composer:
image: composer/composer
I'm able to ADD
the composer.json
and composer.lock
files to the working directory. 我能够ADD
该composer.json
和composer.lock
文件的工作目录。 I can confirm that these two files are in the working directory. 我可以确认这两个文件都在工作目录中。
What I need is for the Dockerfile (or wherever) to also automatically install the dependencies into the working directory. 我需要的是Dockerfile(或任何地方)也自动将依赖项安装到工作目录中。
According to Docker Hub, https://hub.docker.com/r/composer/composer/ , I should be able to docker run -v $(pwd):/app composer/composer install
to install the dependencies but how do I do this in Dockerfile? 根据Docker Hub, https: //hub.docker.com/r/composer/composer/,我应该能够docker run -v $(pwd):/app composer/composer install
来安装依赖项,但我该怎么做在Dockerfile中执行此操作?
Also I'm confused because the -v
flag, https://docs.docker.com/engine/userguide/dockervolumes/ , has to do with mounting the specified host directory into the a container but I've already ADD
ed the necessary files to the working directory. 另外我很困惑,因为-v
标志, https://docs.docker.com/engine/userguide/dockervolumes/ ,与将指定的主机目录安装到容器中有关,但我已经ADD
了必要的文件到工作目录。 All I want to do is install the dependencies. 我想要做的就是安装依赖项。
Thank you for your help. 谢谢您的帮助。
You just need to mount the current directory to /app
when running your composer
container. 您只需要在运行composer
容器时将当前目录挂载到/app
。 I've put together a simple example to illustrate this working at https://gist.github.com/andyshinn/e2c428f2cd234b718239 . 我在https://gist.github.com/andyshinn/e2c428f2cd234b718239上汇总了一个简单的例子来说明这一点。
The key parts here are the volumes
for the composer
part of the application and the restart: 'yes'
on the primary PHP application (the application likely will not run until Composer has run so you will want it to restart). 这里的关键部分是应用程序的composer
部分的volumes
和restart: 'yes'
主PHP应用程序上的restart: 'yes'
(在Composer运行之前,应用程序可能无法运行,因此您希望它重新启动)。
