[英]How to run heroku restart from inside of a rails app?
I understand that from the console I can run heroku restart
.我知道从控制台我可以运行
heroku restart
。 What I'd like to do is to have a button in my app (admin console), where pushing that button runs a heroku restart
.我想做的是在我的应用程序(管理控制台)中有一个按钮,按下该按钮会运行
heroku restart
。 Does anyone know how to do that and if it's possible?有谁知道如何做到这一点,如果可能的话? So the code would look something like this:
所以代码看起来像这样:
<button id="heroku_restart">Restart</button>
$("#heroku_restart").click(function() {
$.post('/restart', {}).done(function(response) {
alert(response)
})
})
class AdminsController
# this is the action mapped to the route /restart
def restart
# code for heroku restart
end
end
So per @vpibano, as of this writing, doing it with the platform-api
is a breeze.因此,根据@vpibano,在撰写本文时,使用
platform-api
是轻而易举的。 Here's the action POSTed to by a button on my website:这是我网站上的按钮发布的操作:
def restart
heroku = PlatformAPI.connect_oauth(ENV["heroku_oauth_token"])
heroku.dyno.restart_all("lastmingear")
render nothing: true
end
As per the description mentioned in the post, the one way of doing it is :根据帖子中提到的描述,一种方法是:
1) First locate the server.pid file
1)首先找到server.pid文件
pid_file = Rails.root.join("tmp", "pids", "server.opid")
2) Now, truncate the contents of the file
2)现在,截断文件的内容
File.open(pid_file, "w") {|f| f.truncate(0)}
3) Finally, run the server using Kernel module:
3) 最后,使用 Kernel 模块运行服务器:
Kernel.exec("rails s")
Note: As rightly, mentioned by @vpibano you will need authentication to access your app.注意:正如@vpibano 所提到的,您将需要身份验证才能访问您的应用程序。
This is not a working model but a way to achieve the requirement.这不是一个工作模型,而是实现需求的一种方式。
Hope it helps!!希望能帮助到你!!
