Node Operator: Kubernetes Node Management Made Simple 陈俊(Joe), Ant Financial Agenda • Background and Motivation • Introduction of Operators • Node-Operator • Advanced Topic: Teardown Cluster fast and convenient • Add & delete Node at any time • Upgrade Master & Node Components reliably • Canary Rollout • Master & Node Component Versions Management Motivation: Work Order Order Deployment Worker Order • Upgrade Nodes Versions • Upgrade Node 10.10.10.1 • Upgrade docker • Upgrade kubelet • Upgrade Node 10.10.10.2 • Upgrade docker • Upgrade kubelet …. Motivation: Work Order

neural network layers, deep learning optimizers, data loading utilities, and multi-gpu, and multi-node support. Functions are executed immediately instead of enqueued in a static graph, improving ease Note: If you use multiprocessing for multi-threaded data loaders, the default shared memory segment size with which the container runs might not be enough. Therefore, you should increase the shared script is available on GitHub. ‣ TransformerXL model: This transformer-based language model has a segment-level recurrence and a novel relative positional encoding. The enhancements that were introduced

内存服务器，该服务器可用于快速原型设计或针对API进行开发。在此模式下， Connect已启用，默 情况下将在启动时创建新的根CA证书。此模式不适用于生产用途，因为它不会将任何数据写入磁盘。 ● disable-host-node-id：将此设置为true将阻止Consul使用来自主机的信息生成确定性节点ID，而 生成将保留在数据目录中的随机节点ID。在同一主机上运行多个Consul代理进行测试时，这非常有用 在版本0.8 ，“debug”，“info”，“warn”和“err”。您始终可以通过consul monitor并使用任何日志级 连接到代理。此外，可以在配置重新加载期间更改日志级别。 ● -node：群集中此节点的名称。这在群集中必须是唯一的。默认情况下，这是计算机的主机名。 ● -node-id：在Consul 0.7.3及更高版本中可用，即使节点或地址的名称发生更改，这也是该节点的 一标识符。这必须是十六进制字符串的形式，长度为36个字符，例如 见的情况），则代理将在启动时生成标识符并将其保留在数据 录中， 以便在代理重新启动时保持相同。如果可能，来自主机的信息将用于生成确定性节点ID，除非 disable-host-node-id设置为true。 ● -node-meta：在Consul 0.7.3及更高版本中可用，它指定与表单节点关联的任意元数据键/值对key: alue。这可以多次指定。节点元数据对具有以下限制： ● 每个节点最多可以注册64个键/值对。

Installation details The VirtualBox kernel module needs a device node to operate. The above make command will tell you how to create the device node, depending on your Linux system. The procedure is slightly Linux kernel sources are used for the build process. Note that the /dev/vboxdrv kernel module device node must be owned by root:root and must be read/writable only for the user. Next, you will have to install has already been installed into your zone, you need to give the zone access to VirtualBox’s device node. This is done by performing the following steps. Start a root terminal and execute: zonecfg -z vboxzone
