＃1-源/克隆问题

Question

我正在尝试通过Docker站起一个PHP application。我可以手动使用它，但是我正在尝试按照最佳做法（例如：单责任形象等）对其进行改进（使其在CI / CD环境中更加可用）

TLDR：

如何可靠地将git repo克隆到本地共享卷中？
如何从.env文件转到特定的git标签？

问题：

将git复制到映射到本地卷的路径中导致本地路径中没有数据/文件
- 我发现有文章提到在构建过程中较早映射空卷将导致路径为空（但我认为这并不直接适用于此）。
docker-compose配置将显示TAO_CODE_TAG的正确值，但在结帐期间失败（视为空）
- 我知道，根据在dockerfile中的调用方式，可能不会发生变量的shell扩展。但是，我看到了它与RUN echo $var一起工作的工作示例？

./。env

PHP_VERSION=7.0
MYSQL_VERSION=5.7
APACHE_VERSION=2.4.32
TAO_CODE_TAG=v3.2-rc02
DB_ROOT_PWD=password ;-)

PS：最终，诸如使用秘密服务器获取安全凭据等之类的事情以及将自动install script与.env文件一起使用的事情将实现为好吧。

＃1-源/克隆问题

我意识到我所需要的只是compose.json和index.php文件，我可以通过<?php // start $stmt = $DB_con->prepare("SELECT * FROM cart WHERE cartuser = '$userid' and cartpend='IN CART'"); $stmt->execute(); if($stmt->rowCount() > 0) { while($row=$stmt->fetch(PDO::FETCH_ASSOC)) { extract($row); //end ?> <form method="get" action="btnchange.php"> <input type="hidden" name="prod_id" value="<?php echo $row['cartno']; ?>"> <tbody> <tr> <td><?php echo $row['cartno']; ?></td> <td><?php echo $row['cartname']; ?></td> <td><?php echo $row['cartprice']; ?></td> <td><input type="text" name="qty" value="<?php echo $row['cartqty']; ?>"></td> <td><?php echo $row['cartsub']; ?></td> <td><span class="label label-primary"><?php echo $row['cartpend']; ?></span></td> <td><button type="submit" name="submit">Submit Quantity</button></b> <td><a class="btn btn-danger btn-xs" href="?delete_id=<?php echo $row['cartno']; ?>" title="click for delete" onclick="return confirm('Sure to Delete?')"><i class="fa fa-trash-o"></i> Remove</a></td> </tr> </tbody> </form> jsdeliver中的dockerfile statements来抓取，然后递归chown / chmod来获取php和apache ADD文件夹中的新文件。

注意：这并不能真正解决通常从github获取源代码的问题，但足以满足我对特定代码库/项目的实际/即刻需求。

我目前正在通过在php和apache派生的图像容器中复制一个多阶段构建来解决代码/ composer-install的问题，如以上各行所示，然后...

php / Dockerfile

FROM composer/composer as Composed
ARG TAO_CODE_TAG # <-- IMPORTANT
RUN mkdir /build && cd /build
WORKDIR /build
ADD https://cdn.jsdelivr.net/gh/oat-sa/package-tao@${TAO_CODE_TAG}/composer.json /build/composer.json # <-- IMPORTANT
RUN composer install --ignore-platform-reqs --no-scripts --no-suggest --no-dev

# ...continues

不幸的是，这对于php和apache实例都是重复的（要求将代码都放入这两个实例中。）我仍在研究一种创建共享的仅源资源的方法，该资源可以通过共享来访问和映射（大多数可能）。

码头工人：git clone结果不在本地卷中，args不扩展
