What is Cloudify

Sometimes it’s hard to maintain a hybrid cloud, too much of dashboards and logins, and approaches. What if someone already providing single place to maintain all cloud? Can you imagine, yes you are correct, its Cloudify, an open-source orchestration software company, now claims it can support all the top five public clouds and Azure, OpenStack, and VMware, with its latest release.

Little surprise, how it’s possible? yeah no more guessing it’s possible through Google’s Kubernetes. Cloudify runs microservices on top of Kubernetes, alongside stateful services such as back-ends on bare-metal and virtual machines (VMs.) It also manages composition and dependency management between services, as well as triggering of auto-scaling of both the micro-services and Kubernetes minions.

The platform offers support for hybrid stacks, orchestrating containers, and non-containerized stacks through new Kubernetes support. It now supports Amazon Web Services (AWS), Azure, Google Compute Platform (GCP), OpenStack, VMware, and cloud-native technologies like Kubernetes and Docker.

The program is based on the Topology and Orchestration Specification for Cloud Applications (TOSCA) standard.

# wget http://repository.cloudifysource.org/cloudify/18.2.28/community-release/cloudify-manager-install-community-18.2.28.rpm

Once its download you can check using “ls” command, and then you can run

Once installed you can check config file in /etc/cloudify folder. If you wish to edit cloudify manager network setting in config.yaml.

Once you modify something in config.yaml, you can validate it using below command, it validates what cfg_manager does.

# cfy_manager validate

cfy_manager validateNow let’s install cloudify manager,

# cfy_managet install --private-ip 192.168.0.3 --public-ip <<your public IP>> --admin-password <<any-password>>

Note: You can mention IP’s and password in config.yaml alone, if you mention in the file, no need to mention in the command. And adding -v will trigger additional logs to /var/log/cloudify/manager/cfy_manager.log

Once you run successfully, can you validate using either command or visit to cfy page using http://<<public-IP>>, login using;

Username: admin
Password: <<your unique password>>

By Command;

# cfy status

cfy status
