Install Azure CLI v 2.0.14

https://github.com/Azure/azure-cli

Login

az login

Create a resource group

az group create -n <resource-group-name> -l ukwest

Multiple agent pools with default node size (Standard_D2_V2)*

Default – 1 agent pool and 3 nodes

az acs create -n <container-service-name> -g <resource-group-name> -t Kubernetes

2 agent pools each with default number of nodes (3)

az acs create -n <container-service-name> -g <resource-group-name> -t kubernetes -a "[{'name':'agentpool1'},{'name':'agentpool2'}]"

Multiple agent pools with custom node size

az acs create -n <container-service-name> -g <resource-group-name> -t kubernetes -a "[{'name':'agentpool1'},{'name':'agentpool2','vmSize':'Standard_D2','count':5}]"

agentpool1 with default node size Standard D2V2 and default no of nodes 3 agentpool2 with VM size Standard_A0 and node count 5

Custom VNET and Ports

Create a custom VNET

az network vnet create -g vnetrg -n vnet007

Use the VNET id (see above) to create a cluster

az acs create -n vnetcs -g vnetrg -t kubernetes --agent-vnet-subnet-id "/subscriptions/<subscription-id>/resourceGroups/vnetrg/providers/Microsoft.Network/virtualNetworks/vnet007"

Use the VNET id and specifiy a custom port

az acs create -n portvnetcs -g vnetrg -t kubernetes --agent-vnet-subnet-id "/subscriptions/<subscription-id>/resourceGroups/vnetrg/providers/Microsoft.Network/virtualNetworks/vnet007" --agent-ports 4005

When using custom VNETS, the kubernetes route tables and a subnet in the Custom VNET specified are not associated. Please follow documentation here to associate them

Storage accounts and Managed Disks

By default, the ACS RP v2 creates managed disks for masters and storage accounts for agents, both of which can be changed to use managed disks or storage accounts.

Use managed disks for masters and agents

az acs create -n storagecs -g storagerg -t kubernetes --master-storage-profile ManagedDisks --agent-storage-profile ManagedDisks

Default master os disk size and agent os disk size are 30GB each Master etcd disk size is 128GB

Use managed disks for masters and agents and specifiy each size

az acs create -n storagecs -g storagerg -t kubernetes --master-storage-profile ManagedDisks --master-osdisk-size 30 --agent-storage-profile ManagedDisks --agent-osdisk-size 120

Delete a cluster

Deleting an ACS cluster deletes the resources it created in a separate resource group it created but leaves the user created resource group untouched*

az acs delete -n <container-service-name> -g <resource-group-name>
