Ansible Roles Make Day to Day Operations Easier
With Red Hat Summit fast approaching let's take a look at a pair of roles today. In previous posts I have covered day-0 operations with the Cluster Config role, and day-1 operations with the Vserver Create role. Now I will cover the repeated task of creating new...
My Name Is Stein!
The OpenStack community is ready with its latest release! As part of the Stein development cycle, NetApp is proud to have contributed in the development of Cinder and Manila. The Stein release includes the following feature enhancements that support the integration of...
How to Install and Use Trident with Docker EE 2.1 Universal Control Plane and Kubernetes
Every day, containerization is becoming a more integral part of IT planning and strategy. The container platform you choose should be able to manage various workloads. Docker Enterprise 2.1 Universal Control Plane (UCP) is one enterprise container platform providing...
Creating Vservers is Even Easier with Roles
I discussed adding NetApp roles and making them available in this post. If you haven’t read that one, please take a moment to read it as it covers the installation and configuration settings to make these roles usable. Much like the Cluster Config role allowed for...
Tenant Data Isolation with Trident
Kubernetes makes managing applications very easy and flexible. Pods can be deployed anywhere, on your local PC for testing, on-prem or in the cloud at anytime. Kubernetes can guarantee a certain number of pods are deployed and running at any given time, and may even...
Simplicity at its finest, Roles for Ansible ONTAP use
Ansible makes the management of NetApp systems easy. Sometimes, though, groups don’t have the time or inclination to create their own playbooks. Ansible has a solution that can ease this issue, it is called roles. An Ansible role is a collection of playbooks,...
Backup & Restore Trident etcd using etcdctl with ONTAP
The etcd database is crucial to NetApp’s Trident storage orchestrator. It stores all backends, storage classes, and volume information used by Trident. This information is necessary to create Persistent Volumes and attach to the backend storage. But what if the data...
Using Ansible Roles to Drive a Full DevOps Workspace Create and Refresh
There is a lot of buzz around DevOps these days often leading to confusion. I hear people asking, “What is DevOps?”, “How do I do DevOps?”, “What do I need for DevOps?”. Everyone needs to go faster these days. AWS puts out over 10,000 changes a DAY! A DevOps...
Trident Adds Cloud Volumes Service for AWS to its Repertoire
We all know and love Trident. It makes provisioning volumes for containers a snap. After a simple Trident setup in a Kubernetes environment, a developer only needs to create a persistent volume claim and call it from their deployment/application. Trident does the rest...
NetApp Encrypted Credentials with Ansible Tower
In a previous post I showed how the ansible-vault can be used to keep passwords secure. What about those locations that only get access to Ansible Tower, and aren’t able to run ansible-vault? We are going to go through the steps to use the Tower credentials to...
Deploying StorageGRID in a Kubernetes Cluster
NetApp’s StorageGRID object store is very easy to use, but it can be challenging to get all of the right infrastructure together to deploy it, especially if you just want to try it out. But under the covers it’s built and deployed as container images, and recent...
Soup-to-Nuts Ansible Module Testing
Sites trying to move into a DevOps model often want to implement a Continuous Integration (CI)/Continuous Deployment (CD) process. This can be challenging without any frames of reference. For our Ansible development we use such a process and want to share that with...
Installing Trident for Kubernetes from a Private Registry
To mitigate risks, many organizations today implement strict security policies. Those policies may limit direct internet access, blocking connections to public software repositories like container image registries. This can make it challenging to install software that...
Can you keep a secret?
As I have mentioned in the past, the normal way of commutation for Ansible, SSH, is not possible with the NetApp systems. We use http and https communications. This however requires a username and password combination for each task run. Interactive playbooks can...
Just the facts ma’am.
One of the things about Ansible that makes it so useful, is its ability to gather information about a system that can then be used in the tasks you run. Because of how the NetApp modules work, this feature isn’t core to them. However, for ONTAP there is the...
Understanding volume migration on OpenStack: Intercluster volume migration
Welcome to the final part in this three-part series on Cinder volume migration. So far, we have explored the basics of migrating volumes and the migration of a volume between backends that reside on the same cluster. In this post, we extend the concept of moving...
Understanding volume migration on OpenStack: Intracluster volume migration
In part two of this series, we will look at an example scenario, where a volume is migrated between backends that lie on the same cluster. In case you haven’t been through part 1 already, you should definitely do so and obtain a general overview of Cinder volume...
Understanding volume migration on OpenStack
One of the cool features offered by OpenStack is the migration of Cinder volumes across backends. Volumes can be moved within an ONTAP cluster, between ONTAP clusters and between an ONTAP and SolidFire cluster. The good thing about migrating volumes is that the...
