Planning and managing your cloud ecosystem and environments is crucial for decreasing manufacturing downtime and sustaining a functioning workload. Within the “Managing your cloud ecosystems” weblog sequence, we cowl completely different methods for making certain that your setup features easily with minimal downtime.
Within the third weblog of the sequence, we’re discussing migrating your employee nodes to a brand new Ubuntu working system. In the event you haven’t already, be sure you additionally take a look at our earlier entries on ensuring workload continuity during worker node upgrades and upgrading your cluster to a new version.
OS help on IBM Cloud Kubernetes Service
IBM Cloud Kubernetes Service helps the Ubuntu OS and repeatedly strikes to newer Ubuntu variations. Presently, the default OS for cluster employee nodes is Ubuntu20.
To keep away from disruptions to your workload, you might be answerable for migrating your employee nodes to new OS variations as they develop into accessible. IBM Cloud notifies customers of upcoming OS releases and deprecations a number of months prematurely to offer customers time to make any essential preparations.
Finest practices for migrating
The steps emigrate to a brand new OS are discovered within the IBM Cloud Kubernetes Service documentation. Nevertheless, earlier than you start, it is best to think about the order by which you migrate your elements. Simply as we described for upgrading cluster versions, all the time begin the migration course of in your improvement setting, adopted by every other pre-production environments. Check your providers alongside the best way and tackle any points that come up earlier than making any modifications in manufacturing. Then, if there are not any points, proceed the migration in your manufacturing setting.
Testing providers throughout OS migrations
Testing your providers all through the method is necessary for minimizing downtime from any points that will come up. Remember that the steps for migrating to a brand new OS contain creating new employee swimming pools that populate with employee nodes on the newest model after which deleting the unique employee swimming pools. Earlier than deleting the unique employee swimming pools, think about scaling them down and preserving them for a number of days earlier than you take away them. This manner, you’ll be able to scale the unique employee pool again up in case your workload experiences disruptions or in case you encounter any points throughout testing. While you decide that your workload is steady and features usually, you’ll be able to take away the unique employee swimming pools.
Wrap up
Preserving your employee node OS updated is necessary for preserving your Kubernetes setup operating easily. When migrating your employee nodes, it’s necessary to work in a single setting at a time and to go away loads of alternative for testing at every step.
In our subsequent and ultimate weblog entry for this sequence, we’ll talk about how one can preserve optimum consistency throughout your setup.
