Example terraform scripts for installing MKE on GCP

[ranyodh]

Description

This is an example of terraform scripts that prepares a cluster on Google Cloud Platform to install Mirantis Kubernetes Engine.

It creates following GCP resources:

• A VPC with specified MTU (default value is 1500) and one subnetwork
• Linux and Windows instances using public images provided by GCP
• Firewall rules to allow internal and external traffic
• A network load balancers for MKE and MSR that targets corresponding unmanaged instance group (along with health checks)

MTU:

The default MTU is set to 1500 (rather than the default 1460). This is to an issue where swarm services fails because Docker network uses 1500 as the default MTU.

Known Issues:

• MSR (Mirantis Secure Registry) installation fails due to invalid SSL certificate for the load balancer IP
• Windows nodes does not work when it is assigned "Kubernetes" orchestration

This looks good to me.

I would have preferred some more sane defaults, but your pattern matches what is in place for AWS.

I don't have credentials to test it, but I think that it is a good start.

Yes, I based the instance types, disk sizes etc on AWS examples.
