The cfy cluster command is used to manage clusters of tenants in Cloudify Manager.

Optional flags

These will work on each command

-v, --verbose - Show verbose output. You can supply this up to three times (i.e. -vvv)
-h, --help - Show this message and exit.

Commands

Start

Usage

cfy cluster start [OPTIONS]

Start a Cloudify Manager cluster with the current manager as the master.

This initializes all the Cloudify Manager cluster components on the current manager, and marks it as the master. After that, other managers can join the cluster by passing this manager’s IP address and encryption key.

Optional flags

--timeout INTEGER - Operation timeout in seconds (The execution itself will keep going, but the CLI will stop waiting for it to terminate) [default: 900]
-o, --options TEXT - Additional options for the cluster node configuration (Can be provided as wildcard based paths (*.yaml, /my_inputs/, etc..) to YAML files, a JSON string or as key1=value1;key2=value2). This argument can be used multiple times
--cluster-host-ip TEXT - The IP of this machine to use for advertising to the cluster
--cluster-node-name TEXT - Name of this manager machine to be used internally in the cluster

Example

$ cfy cluster start

Join

Usage

cfy cluster join [OPTIONS] JOIN_PROFILE

Join a Cloudify Manager cluster on this manager.

A cluster with at least one machine must already exist. Pass the address of at least one member of the cluster as --cluster-join. Specifying multiple addresses, even all members of the cluster, is recommended, to enable joining the cluster even if some of the current members are unreachable. However, it is not required.

Optional flags

--timeout INTEGER - Operation timeout in seconds (The execution itself will keep going, but the CLI will stop waiting for it to terminate) [default: 900]
-o, --options TEXT - Additional options for the cluster node configuration (Can be provided as wildcard based paths (*.yaml, /my_inputs/, etc..) to YAML files, a JSON string or as key1=value1;key2=value2). This argument can be used multiple times
--cluster-host-ip TEXT - The IP of this machine to use for advertising to the cluster
--cluster-node-name TEXT - Name of this manager machine to be used internally in the cluster

Update Profile

Usage

cfy cluster update-profile

Fetch the list of cluster nodes and update the current profile.

Use this to update the profile if nodes are added to the cluster from another machine. Only the cluster nodes that are stored in the profile are contacted in the event of a cluster master failure.

This means that when a cluster administrator adds or removes a node from the cluster, all users must run this command to update their CLI profile.

Example

$ cfy cluster update-profile
...

Fetching the cluster nodes list...
Profile is up to date with 2 nodes

...

Nodes

Usage

cfy cluster nodes [OPTIONS] COMMAND [ARGS]

Manage the nodes in the cluster. (Applicable only in cluster.)

Subcommands

list - Lists the nodes in the cluster.
remove - Remove a node from the cluster.

list

Display a table with basic information about the nodes in the cluster. This is the primary way of retrieving the cluster status.

Example

$ cfy cluster nodes list
HA Cluster nodes
+----------------+-----------+---------+--------+-------------------+----------+-----------+
|      name      |  host_ip  |  state  | consul | cloudify services | database | heartbeat |
+----------------+-----------+---------+--------+-------------------+----------+-----------+
| manager_node_1 | 10.10.1.1 |  leader |   OK   |         OK        |    OK    |     OK    |
| manager_node_2 | 10.10.1.2 | replica |   OK   |         OK        |    OK    |     OK    |
| manager_node_3 | 10.10.1.3 | replica |   OK   |         OK        |    OK    |     OK    |
+----------------+-----------+---------+--------+-------------------+----------+-----------+

remove

Unregister a node from the cluster.

Note that this will not teardown the removed node, only remove it from the cluster. Removed replicas are not usable as Cloudify Managers, so it is left to the user to examine and teardown the node.

Example

$ cfy cluster nodes remove cloudify_manager_W81PXP
Node cloudify_manager_W81PXP was removed successfully!

Set Active

Usage

cfy cluster set-active NODE_NAME

Specify the node that will be the active node (master) in the cluster.

Example

$ cfy cluster set-active cloudify_manager_UAFA8Y
...

cloudify_manager_UAFA8Y set as the new active node

...

Status

Usage

cfy cluster status

Display the current installation status of the Cloudify Manager cluster.

Example

$ cfy cluster status
...

Cloudify Manager cluster initialized!
