Can I configure Cloudify 2.7 with Openstack Icehouse?
I can configure the VM management with the Havana cloud driver but I can not release any application. Any ideas?
Cloudify 2.7 was tested with Openstack Grizzly and Havana; Icehouce wasn't released at the time. Still, it should work on Icehouse since the Openstack APIs are backward compatible.
To understand the issued on your specific environment, please refer to Cloudify's support forums and supply more details.

RedHat Fuse 7.x is offered both on OpenShift and Karaf. While OpenShift version supports containerization of RedHat Fuse application, it inherently makes it highly available I believe. But I am wondering if load balanced and highly available cluster can be formed for RedHat Fuse Karaf version. Earlier till version 6.x, they used to support Fuse Fabric for clustering. The documentation of version 7.x says they have discontinued Fuse Fabric support. If anyone has deployed RedHat Fuse on Karaf in a clustered environment, please let me know how it was achieved.
For my understanding Red Hat Fuse on karaf is just Red Hat supported version of Karaf with bunch of Red Hat Flavored features installed like Camel and Hawtio. OpenShift and Apache Karaf offer two very different levels of containerization. one could say you use OpenShift to run microservices and Apache karaf to run nanoservices.
While you can install and run multiple applications inside Apache Karaf they're still running on the same virtual machine and operating system. You can however create docker image and run Apache karaf on container(s) in Docker, Kubernetes, OpenShift etc like any other application.
This can be useful if you want to group bunch of applications/services together to save resources, share dependencies or just to reduce the amount of different docker containers or deployments.
There's official docker image available for Apache Karaf one can use for reference to create docker image(s) for Red hat fuse on Karaf.
Apache karaf docker - DockerHub
Apache karaf docker - Github
Generally you probably want to create image from a custom karaf assemply that includes all the features and bundles you need to run your applications so when things get added updated you can just swap the image.
Technically you could also use CD/CI pipelines or something like Karaf Cellar to manage multiple karaf instances. This would allow you to add, remove and update functionality of karaf instance even while its running. This however sounds quite complex to pull off and maintain.
As a disclaimer I would like to add that I've not used Apache Karaf or Red Hat Fuse on Karaf with Kubernetes or OpenShift yet. Most of my experience is with running karaf using docker/podman compose or RHEL VM.
In the cloudera website I can see only the Cloudera Quick start VM 5.13.But I need Quick start VM 5.12.
From where or How can I download Quick start VM 5.12
The official website states:
The current Quickstart VM is based on CDH 5.13. Although Cloudera
periodically releases updated versions with newer releases of CDH,
older versions are not available for download.
So you can't download 5.12, at least from official site.
We are considering over which JDK is best suited for the R3 Corda.
However there is some incosistency in the way framework suggests the deployment.
Oracle JDK –
Recommended as per the Corda documentation https://docs.corda.r3.com/getting-set-up.html
Open JDK –
The Corda framework has a defined gradle task for docker deployment as “DockerForm”. This task generates the artifacts which are useful for deploying the Corda node as a docker container. So this task generates a Dockerfile for each node. This file is configured to use OpenJDK by default.
Please let us know the rationale behind this. Does Corda 3.x version support Open JDK as well? Do we have any guideline on which JDK to use in what situation?
Another concern is that eventually Oracle JDK will be a licensed product in future. So does R3 have any plans to support Open JDK as well in future?
As of Corda 3.1, Corda only supports the Oracle JDK 8 JVM, with a minimum supported version 8u171.
There is no current plans to add Open JDK support, but that could change (if, for example, Oracle JDK became a licensed product).
I read the docs refer to Windows and Ubuntu for the installation of Corda. I rarely use Windows these days.
Can Corda work under Ubuntu?
I would prefer to install under Ubuntu.
Yes, Corda runs fine where ever a JAR file can run.
I am trying to setup a grid using Globus Toolkit 6.0 on my Fedora 20 machine. Steps given in Globus's website found to be pretty confusing.
I've installed repositories through .rpm file of gt6(downloaded from toolkit.globus.org). Then I followed steps given in that website. I configured security certificates using SimpleCA.
However while initiating proxy i got some error.
If anyone have solution of this problem, then please suggest,
Or if you've any alternative steps to install and configure Globus Toolkit 6.0 on fedora 20 please suggest...!
Thanx,
I solved my problem.
Error was regarding with certificate creation and signing it...
