OpenShift自定义墨盒和NPM [英] OpenShift Custom Cartridge and NPM

问题描述

我正在为nginx使用社区开发的OpenShift弹药筒.盒带的构建脚本(不做任何修改)运行良好；它使用我提供的配置文件启动nginx服务器.但是，我正在尝试修改构建脚本，以使其首先将目录更改到我的OpenShift存储库中，先运行npm install，然后运行grunt build来构建我创建的Angular应用程序.

I am working with a community-developed OpenShift cartridge for nginx. The cartridge's build script (without any modifications) works well; it starts the nginx server with the configuration file that I provide it. However, I am trying to modify the build script so that it first changes directory into my OpenShift repository, runs npm install and then grunt build to build an Angular application that I have created.

执行此操作时，脚本进入npm install时，我不断收到错误EACCES, mkdir '/var/lib/openshift/xxxxxxxxxx/.npm'.一些 OpenShift论坛帖子试图解决了问题，但似乎需要使用其他解决方案(至少就我而言).

When I do this, I continuously get the error EACCES, mkdir '/var/lib/openshift/xxxxxxxxxx/.npm' when the script gets to npm install. Some OpenShift forum posts have attempted to solve the issue, but it appears as though a different solution is required (at least in my case).

因此，我对是否可以通过这种方式使用npm，或者是否需要创建自己完成所有操作的墨盒感兴趣.

Thus, I am interested in whether or not it is possible to use npm in this way, or if I need to create a cartridge that does all of this myself.

推荐答案

由于我们通常没有创建~/.npm所需的访问权限，因此我们必须找到移动npm缓存(通常为~/.npm)和将npm用户配置(通常为~/.npmrc)配置为可访问的文件夹，以使操作顺利进行.以下信息部分来自我就此问题提交给Redhat的错误报告

Since we do not typically have the access required to create ~/.npm, we have to find ways of moving the npm cache (normally ~/.npm) and the npm user configuration (normally ~/.npmrc) to accessible folders to get things going. The following information comes partially from a bug report that I submitted to Redhat on this matter.

我们必须首先创建一个环境变量来控制.npmrc的位置.我在$OPENSHIFT_DATA_DIR中创建了一个名为.env的文件(可以通过外壳访问我的应用程序).在此文件中，我放置了:

We must begin by creating an environmental variable to control the location of .npmrc. I created a file (with shell access to my application) called .env in $OPENSHIFT_DATA_DIR. Within this file, I have placed:

export NPM_CONFIG_USERCONFIG=$OPENSHIFT_HOMEDIR/app-root/build-dependencies/.npmrc

这会将.npmrc目录移动到我们有权读取/写入的位置.当然，我还必须在$OPENSHIFT_HOMEDIR/app-root/build-dependencies/中创建目录.npmrc.然后，在我的启动前webhook中/在构建脚本的早期，我放置了:

This moves the .npmrc directory to a place where we have the privileges to read/write. Naturally, I have to also create the directory .npmrc in $OPENSHIFT_HOMEDIR/app-root/build-dependencies/. Then, in my pre-start webhook/early in my build script, I have placed:

touch $OPENSHIFT_DATA_DIR/.env

这确保了每次部署/构建时都可以访问配置.npmrc位置的环境变量.现在我们可以移动npm缓存的位置了.首先在.env文件上手动运行touch，然后在$OPENSHIFT_HOMEDIR/app-root/build-dependencies/中创建.npm目录.运行以下命令以完成重新配置:

This ensures that the environmental variable that configures the location of .npmrc will be accessible each time we deploy/build. Now we can move the location of the npm cache. Start by running touch on the .env file manually, and create the .npm directory in $OPENSHIFT_HOMEDIR/app-root/build-dependencies/. Run the following to complete the reconfiguration:

npm config set cache $OPENSHIFT_HOMEDIR/app-root/build-dependencies/.npm

现在，即使不使用NodeJS墨盒，每次部署NPM都应该可以访问.以上目录选择可以根据需要进行更改.

NPM should now be accessible each time we deploy, even if we are not using the NodeJS cartridge. The above directory choices may be changed as desired.
