Managing Sites

A site is a logical grouping of nodes. For example, you can create sites based on the physical location of your nodes, and assign every node that is located at one of your facilities to a single site. Currently, every node of a site must belong to the same cluster. Using sites is important in Great Bear, because you cannot deploy applications directly to nodes, only to sites.

Sites overview

To display the list of your sites, open the Great Bear dashboard, then select Sites.

For every site, the dashboard shows the following information:

• Status: Status of the site.
• Site name: A descriptive name of the site. Select the site to display detailed information and to configure the site.
• Location: Location of the site, for example, London, UK. To change the location of the site, see Configure site.
• Description: Description of the site (if any). To change the description of the site, see Configure site. This column is hidden by default.
• Tags: The tags (labels) assigned to the site.
• Assigned Nodes: List of devices (nodes) assigned to the site, including the name and status of each device.
  • Select the name of the node to change its configuration.
  • If there are no nodes assigned to the site, select Assign nodes to assign a free node to the site.
• Deployed Apps: List of applications deployed to the site, including the name and status of the application. Select an application to display more information about the deployment, and to manage the deployment.

Select a site to display this information in a sidebar.

You can customize the data displayed in the table by showing or hiding columns. Click on the settings icon in the header and select Show columns

To find specific sites, you can:

• Use the column headers to sort the table
• Use the Search field to display matching sites. You can search every data about the sites, including metadata, tags, and names of deployed applications.

To display your sites on a map, select the button .

Hovering over a site shows the description and status of the site. Select the site to display detailed information and to configure the site.

Site status

The status of the site is one of the following:

	No bootstrapped nodes in site	The site has been created but does not have any bootstrapped node assigned to it. Register new nodes if needed, and assign them to the site	NO_STATUS
	Running	All nodes of the site are running. You can deploy applications on this site	RUNNING
	Nodes are initializing	An operation is currently being performed on one or more nodes. Wait until it is finished	IN_PROGRESS
	Serious problem with nodes	All nodes of the site are in ERROR or FAILED state. None of the deployed applications are working	ERROR
	Lost contact with nodes	Check the network accessibility of the site, and the network configuration of its nodes	DORMANT
