Unfortunately, an error has occurred:
timed out waiting for the condition
This error is likely caused by:
- The kubelet is not running
- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)
If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
- ‘systemctl status kubelet’
- ‘journalctl -xeu kubelet’
Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI.
Here is one example how you may list all running Kubernetes containers by using crictl:
- ‘crictl --runtime-endpoint unix:///var/run/cri-dockerd.sock ps -a | grep kube | grep -v pause’
Once you have found the failing container, you can inspect its logs with:
- ‘crictl --runtime-endpoint unix:///var/run/cri-dockerd.sock logs CONTAINERID’
error execution phase wait-control-plane: couldn’t initialize a Kubernetes cluster
To see the stack trace of this error execute with --v=5 or higher
Found multiple CRI endpoints on the host. Please define which one do you wish to use by setting the ‘criSocket’ field in the kubeadm configuration file: unix:///var/run/containerd/containerd.sock, unix:///var/run/cri-dockerd.sock

我想为Heroku构建一个Rails3应用程序。他们使用Postgres作为他们的数据库,所以我通过MacPorts安装了postgres9.0。现在我需要一个postgresgem并且共识是出于性能原因你想要pggem。但是我对我得到的错误感到非常困惑当我尝试在rvm下通过geminstall安装pg时。我已经非常明确地指定了所有postgres目录的位置可以找到但仍然无法完成安装:$envARCHFLAGS='-archx86_64'geminstallpg--\--with-pg-config=/opt/local/var/db/postgresql90/defaultdb/po
在选择我想要运行操作的频率时,唯一的选项是“每天”、“每小时”和“每10分钟”。谢谢!我想为我的Rails3.1应用程序运行调度程序。 最佳答案 这不是一个优雅的解决方案,但您可以安排它每天运行,并在实际开始工作之前检查日期是否为当月的第一天。 关于ruby-如何每月在Heroku运行一次Scheduler插件?,我们在StackOverflow上找到一个类似的问题: https://stackoverflow.com/questions/8692687/
我对最新版本的Rails有疑问。我创建了一个新应用程序(railsnewMyProject),但我没有脚本/生成,只有脚本/rails,当我输入ruby./script/railsgeneratepluginmy_plugin"Couldnotfindgeneratorplugin.".你知道如何生成插件模板吗?没有这个命令可以创建插件吗?PS:我正在使用Rails3.2.1和ruby1.8.7[universal-darwin11.0] 最佳答案 随着Rails3.2.0的发布,插件生成器已经被移除。查看变更日志here.现在
我打算为ruby脚本创建一个安装程序,但我希望能够确保机器安装了RVM。有没有一种方法可以完全离线安装RVM并且不引人注目(通过不引人注目,就像创建一个可以做所有事情的脚本而不是要求用户向他们的bash_profile或bashrc添加一些东西)我不是要脚本本身,只是一个关于如何走这条路的快速指针(如果可能的话)。我们还研究了这个很有帮助的问题:RVM-isthereawayforsimpleofflineinstall?但有点误导,因为答案只向我们展示了如何离线在RVM中安装ruby。我们需要能够离线安装RVM本身,并查看脚本https://raw.github.com/wayn

我刚刚为fedora安装了emacs。我想用emacs编写ruby。为ruby提供代码提示、代码完成类型功能所需的工具、扩展是什么? 最佳答案 ruby-mode已经包含在Emacs23之后的版本中。不过,它也可以通过ELPA获得。您可能感兴趣的其他一些事情是集成RVM、feature-mode(Cucumber)、rspec-mode、ruby-electric、inf-ruby、rinari(用于Rails)等。这是我当前用于Ruby开发的Emacs配置:https://github.com/citizen428/emacs
