Configuration

The Mirantis Kubernetes Engine (MKE) 4 configuration file contains an opinionated configuration on how to set up an MKE cluster.

With the MKE configuration file, you can:

• Define the number of nodes in the cluster.
• Define ways to access the nodes.
• Enable or disable certain MKE components.
• Configure MKE component features

Once set, the MKE configuration file is translated into a more complex blueprint that contains the granular details on how to set up the cluster.

Create configuration

1. Generate the default MKE configuration file by running:

   mkectl init > mke.yaml

2. Modify the hosts section of the MKE configuration file, to apply the configuration to a set of pre-existing machines that you have set up in advance:

   hosts:
   - ssh:
       address: 18.224.23.158
       keyPath: "/absolute/path/to/private/key.pem"
       port: 22
       user: root
     role: controller+worker
   - ssh:
       address: 18.224.23.158
       keyPath: "/absolute/path/to/private/key.pem"
       port: 22
       user: ubuntu
     role: worker
   - ssh:
       address: 18.117.87.45
       keyPath: "/absolute/path/to/private/key.pem"
       port: 22
       user: ubuntu
     role: worker

Choose addons

A core component of MKE 4 is a default set of curated and tested addons that you can install by running mkectl init and subsequently applying the generated configuration file.

Using the MKE configuration file, you can enable and disable the MKE 4 addons, as well as modify their settings. In addition, you can use the mkectl init command with the --blueprint option to print the generated blueprint that reflects your current MKE 4 configuration.
