CloudStack Kubernetes Service – Cluster Auto-scaling | CloudStack Feature First Look
Since the addition of CloudStack Kubernetes Service, users can deploy and manage Kubernetes clusters in CloudStack. This not only makes CloudStack a more versatile and multifaceted application, but also reduces the gap between virtualization and containerization. As with any step in the right direction, it came with a few challenges, and one of them was […]
Share ISO from UI | CloudStack Feature First Look
CloudStack supports sharing templates and ISOs between accounts and projects through the API ‘updateTemplatePermissions’ and sharing templates through the UI. However, prior to version 4.15, it was not possible to share ISOs from the UI. This feature introduces support for sharing ISOs through different accounts and / or projects via the UI. With this feature, […]
CloudStack Kubernetes Service
For a while, the CloudStack community has been working on adding support for containers. ShapeBlue successfully implemented the CloudStack Container Service and donated it to the project in 2016, but it was not completely integrated into the codebase. However, with the recent CloudStack 4.14 LTS release, the CloudStack Kubernetes Service (CKS) plugin adds full Kubernetes […]
KVM Rolling Maintenance | CloudStack Feature First Look
In a typical scenario prior to this feature, the administrator had to automate the process of setting hosts in maintenance before upgrading, usually using external automation tools. This feature allows administrators to perform the entire process within CloudStack, providing a flexible framework that allows defining custom scripts to execute on each host. CloudStack executes these scripts […]
Direct Download agnostic of the storage provider | CloudStack Feature First Look
Introduction In a previous post, ShapeBlue’s Boris Stoyanov introduced a feature for KVM which allows administrators to register templates and ISOs without needing secondary storage as an intermediate cache. This feature is known as Direct Download in CloudStack. Without an intermediate cache, the templates and ISOs direct download registration process differs from the usual process, […]
Enable sending of arbitrary configuration data to VMs | CloudStack Feature First Look
This feature allows the sending of arbitrary additional VM configurations to user VMs on CloudStack and is supported by KVM, XenServer and VMware hypervisors. The administrator enables or disables this feature by the global configuration ‘enable.additional.vm.configuration’ which is disabled by default. To add a second layer of security, the administrator must explicitly set a comma-separated […]
Hosts stuck in PrepareForMaintenance state | CloudStack Feature First Look
The process of setting a host into maintenance in CloudStack requires an administrator to ask for ‘prepare for maintenance’, either via API or through the UI on a host. When CloudStack receives the request to prepare the host for maintenance, the host state is set to ‘PrepareForMaintenance’ and any VM running on the host start […]
Improvements for Template Direct Download | CloudStack Feature First Look
For some time now, CloudStack has supported the direct download of user templates for the KVM hypervisor. This basically allows user to register a template (whilst bypassing secondary storage) and directly download and install it to primary storage where it can be used for deployment: With CloudStack 4.14, this has been improved by adding direct […]
What’s coming in the new CloudMonkey 6.0? | CloudStack Feature Deep Dive
Background The original CloudMonkey was contributed to the Apache CloudStack project on 31 Oct 2012 under the Apache License 2.0. It is written in Python and shipped using the Python CheeseShop, and since its inception has gone through several refactors and rewrites. While this has worked well over the years, the installation and usage have been limited […]
Integration Testing within CloudStack – Marvin
Integration testing – What it is and why SDLC needs it. What is Integration testing? This is a type of testing where multiple components are combined and tested working together. There are different aspects of integration testing depending on the project and component scale, but usually it comes down to validating that different modules can […]
