Using the Cloudify Manager
A blueprint can contain multiple files. These files can reside under a single directory with subdirectories or in an archive. Although the Cloudify CLI can manage the archiving process for you during upload, you might want to create archives prior to uploading the blueprint, so that you can keep them in a fileserver, upload them via the Cloudify Console, or send them to others. Single YAML file blueprints Cloudify Console supports single YAML file blueprints.
Before you can deploy a blueprint, you must upload the blueprint to the Cloudify Manager. You can upload a blueprint using the CLI. You can also upload using the Cloudify Console. Either use a blueprint that you have written or download an example blueprint to upload. Uploading a Blueprint using the Cloudify Console You can upload a pre-packaged blueprint archive through the Cloudify Console in tar, tar.gz, tar.bz, or zip formats.
In order for Cloudify to deploy your application, it reads the uploaded blueprint YAML (the logical representation) and manifests a model called a deployment. A deployment is a “technical” drilled-down representation of your application. For example, if a blueprint describes a single server node that is defined to deploy multiple instances, the deployment will comprise the instances themselves, together with their unique identifiers. Creating a deployment does not actually create any resources, it simply generates a “physical” representation of your application from a “logical” (blueprint) representation and stores it in the database.
Multi-tenancy is a Cloudify Premium-edition feature that enables you to create multiple independent logical groups of resources as isolated environments on a single Cloudify Manager. A tenant is a logical entity that contains a group of Cloudify resources such as blueprints, deployments, executions, plugins and secrets. Using multi-tenancy is useful when you want to limit access to a specific set of data to a defined set of users. With the multi-tenant ability, you can create tenants and divide your Cloudify resources between them.
After you have created a deployment, you must execute the process that will implement your application’s actual manifestation in your selected environment. This process is achieved using the install workflow, which is the default workflow provided by Cloudify for deploying your application. You can create workflows for different types of actions such as deploying code, changing the infrastructure state, and even for overriding the default Install Workflow. Executing a Workflow via the CLI To execute a workflow run the following command.
The visibility of the resource defines who can see the resource. It can have one of the following values: private - The resource is visible to the user that created the resource, the tenant’s managers and the system’s admins. Only these users can see or use this resource. tenant - The resource is visible to all users in the current tenant. (Default value) global - The resource is visible to all users in all tenants across the manager.
With Cloudify, you can update a deployment. For example, if you have a sizable, complex deployment of webservers and databases, and you need to add a new type of database that must be connected to some of the existing webservers, you would update your deployment. Updating a deployment means that, instead of creating a new deployment from a blueprint to add the new nodes, you add and connect them in your existing deployment, while retaining the state of your current settings.
After you have uninstalled an application, you can delete it from Cloudify Manager. After you uninstall an application, all of its static and runtime properties are still stored in the Manager’s database and the deployment-specific agents continue to consume resources on the Manager. Deleting a deployment enables you to clean the environment of those excess artifacts. To delete a deployment from the manager with the CLI, run: cfy deployments delete nodecellar The delete options are:
Deleting a blueprint removes its model from the database and deletes its resources from the fileserver. Deleting a blueprint does not delete the deployments created from that blueprint or resources of those deployments. Notice that blueprints that are used in other blueprints are protected for deletion until it has no users or it’s deleted with the force flag. To delete a blueprint from the manager with the CLI, run: cfy blueprints delete [OPTIONS] BLUEPRINT_ID The delete options are:
About For enabling a fully shareable blueprint or a resource this two abilities were added: importing a catalog blueprint and adding a namespace context to any import available resource. With those two it is possible to share any common blueprint definitions, from a simple data types definitions through an architecture common pattern (like creating an openstack VM with all of its requirements) and up to entire micro-services that are found across in several services.
If you have a Premium version of Cloudify Manager, an admin user can create a cluster of Cloudify Managers to enable high availability. It is recommended that you have three Cloudify Managers in a cluster for the following reasons: To ensure resilience in the case of a failure To reduce the probability of multiple hot standbys being activated as the active Manager in the event of a network failure (split-brain.
The secrets store provides a secured variable storage (key-value pairs) for data that you do not want to expose in plain text in Cloudify blueprints, such as login credentials for a platform. The values of the secrets are encrypted in the database. We use the Fernet encryption of cryptography library, which is a symmetric encryption method that makes sure that the message encrypted cannot be manipulated/read without the key. When you create a secret, the key value can be a text string or it can be a file that contains the key value.
When in maintenance mode, Cloudify Manager activity is suspended. It rejects all requests, and does not perform any action other than to display the status of the Manager and it’s version, and to execute sub-commands of the maintenance mode. Cloudify Manager has three maintenance states, activated, activating, and deactivated. To view the current maintenance state of the Manager, run cfy maintenance-mode status. The state is also displayed when you run cfy status (so long as the state is not deactivated).
Cloudify uses RabbitMQ as its broker, and supports configurable security. Authentication When installing the Cloudify Manager, RabbitMQ credentials can be provided in the configuration file before running cfy_manager install or cfy_manager configure. The default location of this configuration file is /etc/cloudify/config.yaml. Username It is suggested that you change the username to something other than the default. It is recommended that you use only upper and lower case letters and numbers for the username.
This page briefly explains the different log files that will be available on the Cloudify Manager host. Downloading the logs Running cfy logs download will download a tar gzipped file containing the log files discussed in this page. This archive will be vital when requesting support with your Cloudify Manager. cfy logs download requires SSH access to your Cloudify Manager machine. This means that the SSH key and the SSH username must be set in your CLI profile.
A snapshot is a .zip file that contains all relevant data describing the state of a Cloudify Manager the moment the snapshot is created on this Manager. There are four basic operations associated with snapshots: creating, downloading, uploading and restoring. For detailed information about snapshot-related CLI commands, click here. Common use cases for snapshots are: Backing up the Manager to be able to restore its state later on, should it become inconsistent or broken for whatever reason.
What are Cloudify roles? A role is a group of permissions that are required by a certain type of user to work in Cloudify. You can assign roles to a user to give that user the permissions that are defined in the role. You can also assign roles to user groups to give the permissions that are defined in the role to all of the users in the group. If a user is a member of more than one group, then the user has all of the permissions in the role defined for the user specifically, in addition to all of the permissions defined for all of the roles the user is assigned to via groups.
Cloudify provides a user management mechanism, so you can define different users with different permissions, and upon login perform authentication and authorization to control the users’ access to resources.
Cloudify provides a user management mechanism, so you can define different users with different permissions, and upon login perform authentication and authorization to control the users’ access to resources. The users can be either defined and managed in Cloudify itself, or you can configure your Manager to integrate with an LDAP-based user-management system. You must select one of these options, as you cannot do both, and you must configure your manager accordingly upon installation or immediately afterwards, when no actions were performed on it yet.
Cloudify enables integration with your local Okta system to authenticate users. In this guide, the configuration steps required to enable Okta authentication are described. openssl version To enable Okta integration, the openssl package on Cloudify Manager needs to be of version 1.0.2. If you are running a Cloudify image this is already the case, however if you are installing make sure to update the openssl package prior to the Okta configuration.
Overview Cloudify lets you extend the user authentication mechanism so that you can support different external authentication services. You can authenticate users with the basic username/password support in Cloudify or you can configure your Manager to integrate with an external authenticator, such as an LDAP-based user-management system. External authentication is an extension to the Cloudify Manager not included in the standard Manager installation. To support a new external authentication mechanism, you must add a dedicated module in the specified format to a specific location in the Manager and restart the REST services.
