我正在尝试使用 docker-compose 在 docker 容器中运行 redis:
docker-compose.yml:
redis:
image: redis:3.0.4
命令:
$ docker-compose up
输出:

出于某种原因，redis 会启动多次，有时只会启动一次(这是随机的)。在日志中有很多喜欢的东西，比如:
redis_1 | 1:signal-handler (1444144597) Received SIGTERM scheduling shutdown...
环境:
docker-compose version: 1.4.0
Docker version 1.8.0, build 0d03096
docker-machine version 0.4.0 (9d0dc7a)
编辑:它仅在使用 docker-compose 时发生。在使用 docker run redis:304 运行 redis 时，它工作正常。
最佳答案
这里讨论了类似的问题:https://github.com/docker/compose/issues/2148
将 --force-recreate 添加到 docker-compose 命令似乎可以阻止它。
关于docker 中的 Redis 多次启动/重启？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32973875/
总的来说，我对ruby还比较陌生，我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础，我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
我试图在一个项目中使用rake，如果我把所有东西都放到Rakefile中，它会很大并且很难读取/找到东西，所以我试着将每个命名空间放在lib/rake中它自己的文件中，我添加了这个到我的rake文件的顶部:Dir['#{File.dirname(__FILE__)}/lib/rake/*.rake'].map{|f|requiref}它加载文件没问题，但没有任务。我现在只有一个.rake文件作为测试，名为“servers.rake”，它看起来像这样:namespace:serverdotask:testdoputs"test"endend所以当我运行rakeserver:testid时
作为我的Rails应用程序的一部分，我编写了一个小导入程序，它从我们的LDAP系统中吸取数据并将其塞入一个用户表中。不幸的是，与LDAP相关的代码在遍历我们的32K用户时泄漏了大量内存，我一直无法弄清楚如何解决这个问题。这个问题似乎在某种程度上与LDAP库有关，因为当我删除对LDAP内容的调用时，内存使用情况会很好地稳定下来。此外，不断增加的对象是Net::BER::BerIdentifiedString和Net::BER::BerIdentifiedArray，它们都是LDAP库的一部分。当我运行导入时，内存使用量最终达到超过1GB的峰值。如果问题存在，我需要找到一些方法来更正我的代
Rails2.3可以选择随时使用RouteSet#add_configuration_file添加更多路由。是否可以在Rails3项目中做同样的事情？ 最佳答案 在config/application.rb中:config.paths.config.routes在Rails3.2(也可能是Rails3.1)中，使用:config.paths["config/routes"] 关于ruby-on-rails-Rails3中的多个路由文件，我们在StackOverflow上找到一个类似的问题
我的代码目前看起来像这样numbers=[1,2,3,4,5]defpop_threepop=[]3.times{pop有没有办法在一行中完成pop_three方法中的内容？我基本上想做类似numbers.slice(0,3)的事情，但要删除切片中的数组项。嗯...嗯，我想我刚刚意识到我可以试试slice! 最佳答案 是numbers.pop(3)或者numbers.shift(3)如果你想要另一边。 关于ruby-多次弹出/移动ruby数组，我们在StackOverflow上找到一
我需要从一个View访问多个模型。以前，我的links_controller仅用于提供以不同方式排序的链接资源。现在我想包括一个部分(我假设)显示按分数排序的顶级用户(@users=User.all.sort_by(&:score))我知道我可以将此代码插入每个链接操作并从View访问它，但这似乎不是“ruby方式”，我将需要在不久的将来访问更多模型。这可能会变得很脏，是否有针对这种情况的任何技术？注意事项:我认为我的应用程序正朝着单一格式和动态页面内容的方向发展，本质上是一个典型的网络应用程序。我知道before_filter但考虑到我希望应用程序进入的方向，这似乎很麻烦。最终从任何

刚入门rails，开始慢慢理解。有人可以解释或给我一些关于在application_controller中编码的好处或时间和原因的想法吗？有哪些用例。您如何为Rails应用程序使用应用程序Controller？我不想在那里放太多代码，因为据我了解，每个请求都会调用此Controller。这是真的？ 最佳答案 ApplicationController实际上是您应用程序中的每个其他Controller都将从中继承的类(尽管这不是强制性的)。我同意不要用太多代码弄乱它并保持干净整洁的态度，尽管在某些情况下ApplicationContr
