CLI 示例:在 Azure Batch 中创建和管理 Linux 池CLI example: Create and manage a Linux pool in Azure Batch

这些脚本演示了 Azure Batch 中一些可用于在 Azure CLI 中创建和管理 Linux 计算节点池的命令。These script demonstrates some of the commands available in the Azure CLI to create and manage a pool of Linux compute nodes in Azure Batch.

如果选择在本地安装并使用 CLI,本快速入门要求运行 Azure CLI 2.0.20 版或更高版本。If you choose to install and use the CLI locally, this quickstart requires that you are running the Azure CLI version 2.0.20 or later. 运行 az --version 即可查找版本。Run az --version to find the version. 如果需要进行安装或升级,请参阅安装 Azure CLI 2.0If you need to install or upgrade, see Install Azure CLI 2.0.

示例脚本Example script


# Create a resource group.
az group create --name myResourceGroup --location chinanorth

# Create a Batch account.
az batch account create \
    --resource-group myResourceGroup \
    --name mybatchaccount \
    --location chinanorth

# Authenticate Batch account CLI session.
az batch account login \
    --resource-group myResourceGroup \
    --name mybatchaccount

# Retrieve a list of available images and node agent SKUs.
az batch pool node-agent-skus list

# Create a new Linux pool with a virtual machine configuration. The image reference 
# and node agent SKUs ID can be selected from the ouptputs of the above list command.
# The image reference is in the format: {publisher}:{offer}:{sku}:{version} where {version} is
# optional and defaults to 'latest'.
az batch pool create \
    --id mypool-linux \
    --vm-size Standard_A1 \
    --image canonical:ubuntuserver:16.04.0-LTS \
    --node-agent-sku-id "batch.node.ubuntu 16.04"

# Resize the pool to start some VMs.
az batch pool resize \
    --pool-id mypool-linux \
    --target-dedicated 5

# Check the status of the pool to see when it has finished resizing.
az batch pool show \
    --pool-id mypool-linux

# List the compute nodes running in a pool.
az batch node list \
    --pool-id mypool-linux

# If a particular node in the pool is having issues, it can be rebooted or reimaged.
# The ID of the node can be retrieved with the list command above.
# A typical node ID is in the format 'tvm-xxxxxxxxxx_1-<timestamp>'.
az batch node reboot \
    --pool-id mypool-linux \
    --node-id tvm-123_1-20170316t000000z

# One or more compute nodes can be deleted from the pool, and any
# work already assigned to it can be re-allocated to another node.
az batch node delete \
    --pool-id mypool-linux \
    --node-list tvm-123_1-20170316t000000z tvm-123_2-20170316t000000z \
    --node-deallocation-option requeue
