Question

方案

我创建了一个包含多个节点的池（基本映像是Ubuntu Server 16.04），并提供以下启动命令： /bin/bash -c 'set -o pipefail; export DEBIAN_FRONTEND=noninteractive ; sudo -E apt update ; sudo -E apt upgrade -y ; sudo -E apt-get install -y --no-install-recommends apt-transport-https curl software-properties-common ; curl -fsSL "https://sks-keyservers.net/pks/lookup?op=get&search=0xee6d536cf7dc86e2d7d56f59a178ac6c6238f52e" | sudo -E apt-key add - ; sudo -E apt-add-repository "deb https://packages.docker.com/1.13/apt/repo/ ubuntu-$(lsb_release -cs) main" ; sudo -E apt-get update ; sudo -E apt-get install -y docker-engine ; sudo usermod -a -G docker $USER ; sudo -E service docker start ; journalctl -xe; wait'

该命令用于安装Docker Engine的唯一目的。另请注意，我删除了set -e选项，以便能够运行命令journalctl -xe并捕获以下错误。

错误

创建上述池时，某些节点将无法启动任务。该行为似乎是随机的，因为并非总是节点失败，并且如上所述，其他节点不会失败。行为不依赖于节点的大小（我尝试了D2_v3和NC6）。

这是journalctl -xe：

在创建网络界面时似乎出现了问题，但我不确定是什么，尤其是如何修复它。

Answer 1

更新后的答案，2017-10-18：

此问题已通过Canonical UbuntuServer 16.04-LTS的latest平台映像修复，并再次与Go / Docker配合使用。

原始答案：

您的代码没有任何问题。 Canonical UbuntuServer 16.04-LTS 201709190平台图像（此时也是latest）和Go / Docker有一个issue。

在问题解决后，暂时将图像版本设置为201708151。

顺便说一下：如果您使用的是Docker和Azure Batch，则应该查看提供此功能的Batch Shipyard。（完全披露：我是此代码的撰稿人。）
