Overview

A Cloudify Manager is a compute host running Cloudify components.

Deploying Cloudify Manager RPM

The Cloudify Manager RPM file includes all Cloudify Manager components and their dependencies. The RPM is self-contained and the installation process does not require an internet connection.

Download the Cloudify Manager RPM file
Copy the RPM file to your target host
From the terminal of your target host, run:
```
sudo yum install <RPM file path>
```
Customize Cloudify Manager’s settings
Install on a single All-In-One host
Cloudify Manager is ready for use at http(s)://<manager_public_address>

Cloudify Manager Configuration

Once RPM is deployed, file /etc/cloudify/config.yaml (View in GitHub) contains all installation options, including:

Setting	Description	Comments
`admin_password`	Administrator password	Recommended. If you do not specify an administrator password in the command-line or the config.yaml file, the installation process generates a random password and shows it as output in the installation logs.
`private_ip`;`public_ip`	Private and public IP addresses	Can be set in `config.yaml` or as command line argument to `cfy_manager install`
`ssl_enabled`	External REST communications over HTTPS	Recommended.
`import_resolver`	Local path replacement for remote resources with a URL
`skip_sanity`	Skip sanity check after installation	Not recommended.
`extra_env`	Additional environment variables (see below)
`ssl_inputs`	SSL communication settings
`cloudify_license_path`	Path to Cloudify license file
`task_retries`	Maximum number of retries for a task. `-1` means infinite retries	This applies to all workflows.
`task_retry_interval`	Minimum wait time (in seconds) between task retries	This applies to all workflows.

You can validate the configurations are valid using cfy_manager validate command.

Adding Environment Variables

In certain cases, it may be required to add environment variables to the processes that run Cloudify Manager. For example, certain organizations impose restrictions on the installation-default temporary files directory (usually /tmp), requiring the adjustment of the TEMP / TMP / TMPDIR environment variables accordingly.

This can be achieved by providing additional settings in config.yaml:

The extra_env key under the restservice category contains a dictionary of environment variables to be added to Cloudify’s REST Service.
The extra_env key under the mgmtworker category is read as a dictionary of environment variables to be added to Cloudify’s Management Workers Service.

For example, to override the TEMP environment variable with /var/tmp:

mgmtworker:
  extra_env:
    TEMP: /var/tmp

restservice:
  extra_env:
    TEMP: /var/tmp

Multi-Network Management

Cloudify Manager uses Cloudify Agents to execute tasks and collect information about the resources that it manages. You must specify the Cloudify Manager IP addresses or DNS names that your agents will use to communicate with it.

You cannot configure multi-network management on Cloudify Manager images.
If no manager network interface is specified in the blueprint, the agent connects to the default interface, which is configured with the private_ip flag during the RPM installation process.

Multi-network management can be configured before installing a new Manager and after.

Option 1: Configure Multi-network Management before Installing a New Manager

The Cloudify Manager networks are configured in the networks section of the /etc/cloudify/config.yaml file, for example:

networks:
    default: <privately_routable_ip>
    external: <externally_routable_ip>

You must specify the name of the Cloudify Manager network for each agent that is deployed in your blueprint with this syntax:

  host:
    type: cloudify.nodes.Compute
    properties:
      agent_config:
        network: external
        install_method: remote
        user: { get_input: username }
        key: { get_secret: agent_key_private }
        port: 22
      ip: { get_input: host_ip }

Option 2: Add New Networks to a Running Manager

In order to add networks to a running Manager use the cfy_manager add-networks command.
New networks should be supplied as a JSON string. It is possible to add multiple new networks using one command (as shown in the example below).
Please note that you can only add networks with unique names, otherwise an error will be raised.
If using a Cloudify Manager cluster, the command will add the network only for the node it is run on. The command needs to be run separately on each node in the cluster, for the newly-installed agents to be able to contact all nodes in the cluster.
```
cfy_manager add-networks --networks '{"<network-name>": "<ip>", "<network-name>":"<ip>"}'
```

All-In-One Installation

To install the Cloudify Manager, run:

cfy_manager install [--private-ip <PRIVATE_IP>] [--public-ip <PUBLIC_IP>] [--admin-password <password>] [-v]

The arguments are optional if already configured in config.yaml (see Cloudify Manager’s settings)

Uninstalling Cloudify Manager

Data Loss

Uninstalling the Cloudify Manager erases all Cloudify data and is irreversible.

To uninstall the Cloudify Manager, run:
```
sudo cfy_manager remove -f
```
To remove all of the files that the installation process extracted, run:
```
sudo yum remove cloudify-manager-install
```
