Create hosts with Cloud.ru Advanced hostprovider

Olga Semme

This article describes how to create hosts via ADCM based on the Cloud.ru Advanced hostprovider.

IMPORTANT

Before adding hosts to ADCM based on the Cloud.ru Advanced hostprovider, make sure that the hostprovider is installed in ADCM.

The steps for adding hosts to ADCM based on the Cloud.ru Advanced hostprovider are given below:

Select the left navigation menu item Hosts and on the page that opens, click Create host.

Adding a host to ADCM

In the window that opens:

Select the hostprovider in the Hostprovider field. Note that hostproviders appear in the list with the names assigned to them when they were added to ADCM.
Enter the host name in the Name field.

Click Create.

Description of the host to be added

CAUTION

When creating hosts for the ADH and ADPS products, you should define an FQDN in the Name field (e.g. test.ru-central1.internal).
For the ADS and ADS Control products, FQDNs are required if the ADPS product is used.
For the ADQM product, FQDNs are required if Kerberos authentication is used.
ADB starting with the 6.23.3.44 version supports both FQDN and short host names. For the previous ADB versions, it is not recommended to use FQDNs (as FQDNs cause errors during the Expand action and a workaround is needed).
In other cases, both short host names and FQDNs are allowed in the Name field.

Return to the Hosts page and switch to configure the added host. To do this, click the hostname in the Name column.

Host configuration

The purpose of the parameters is given below.

Hosts configuration parameters
Group	Parameter	Description	Default value
—	Connection address	IP address of the virtual machine for connecting via SSH	—
—	Secondary NIC IP address	IP address of the second network interface of the virtual machine	—
—	Port	SSH port	22
—	Username	Username for connecting to the virtual machine via SSH	root
—	Ansible become	When set to `true`, by default sets `root` rights to this user	true
—	SSH args	Additional SSH connection options	-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null
—	Additional users groups	Adds the user to additional Linux groups when the virtual machine is initialized. For example, in an Altlinux image, the user `ansible` should be added to the `wheel` group	—
instance	Login	The user that will be created for the VM	—
	Public SSH key	Public SSH key for user	—
	Cloud-init timeout	Timeout for cloud-init to finish running tasks, in seconds	300
	Assign public ip	Set to `true` if a public IP address needs to be added	false
	Assign secondary NIC	Set to `true` if it is necessary to connect an additional network interface to a virtual machine in the specified subnet	false
	Assign internal ip	Internal IP address attached to the instance	—
	ADCM control connection address type	Private or public address for connecting to a virtual machine	private
	Init script	Initialization script	—
	Availability Zone	Cloud.ru Advanced data centers located in different regions of Russia. Currently, Cloud.ru Advanced has three zones: `ru-moscow-1a`, `ru-moscow-1b`, `ru-moscow-1c`	AZ1
	Image family	A family of operating systems on the basis of which virtual machines will be created. The newest image from the specified family will be used	CentOS 7.6
	Image id	Latest imageID for the provided *Image Family*	—
	Flavor	A VM configuration that defines the characteristics of its resources. The template determines the number and type of CPU, the amount of RAM, and some other VM parameters	s7n.medium.2
	Disk type	Disk type. One of: `High I/O`, `Ultra-High I/O`	High I/O
	Disk size, GB	Disk size	50
	Additional disks (JSON)	Additional disk parameters in JSON format. For example: `[{ "name": "disk1", "type": "SAS", "size": 20 }, { "name": "disk2", "type": "SSD", "size": 10 }]`	—
	Security Group IDs	An optional field where you can set default Security Group ID value for all created virtual machines. If the *Security Group IDs* values are set simultaneously in the hostprovider settings and when creating the VM, then priority is given to the latter	—
	Labels	Sets the labels values for the created virtual machine. If the *Labels* values are set simultaneously in the hostprovider settings and when creating the VM, then priority is given to the latter	—

Return to the Hosts page. In the line containing the added host, click the icon and select the Init action. Then confirm the action in the window that opens.

Once an action is started, ADCM displays its execution progress and result on the Jobs page. From this page you can go to the page of an individual task (by clicking on the task name) to see the internal stages of its execution and analyze errors, if any.
