How do I change the replica set in Kubernetes?
You can easily change the number of pods a particular ReplicaSet manages in one of two ways:
- Edit the controllers configuration by using kubectl edit rs ReplicaSet_name and change the replicas count up or down as you desire.
- Use kubectl directly. For example, kubectl scale –replicas=2 rs/web .

How are replica sets often created?
When you deploy a pod within a Kubernetes cluster, you will often create replicas of the pod to scale an application or service. The best way to control these replicas is via a ReplicaSet, which makes sure specified replica pods are always running at the desired state.
What’s the difference between a deployment and a replicaset?
A ReplicaSet ensures that a specified number of pod replicas are running at any given time. However, a Deployment is a higher-level concept that manages ReplicaSets and provides declarative updates to Pods along with a lot of other useful features.
Do you need to install MongoDB to deploy a replica set?

How to create a replica set in Azure AD DS?
To improve the resiliency of an Azure Active Directory Domain Services (Azure AD DS) managed domain, or deploy to additional geographic locations close to your applications, you can use replica sets. Every Azure AD DS managed domain namespace, such as aaddscontoso.com, contains one initial replica set.
What should the name of a replica set be?
If your application connects to more than one replica set, each set should have a distinct name. Some drivers group replica set connections by replica set name. Set net.bindIp option to the hostname/ip or a comma-delimited list of hostnames/ips, and Set any other settings as appropriate for your deployment.
