akamalov / Terraform-Splunk

Terraform template to build a splunk cluster

#Introduction

• New version with packer for servers that don't have internet access to download package from S3.
• In the packer vars, user is set to splunk and base folder to /opt
• Check the packer/README.md to build your image and then use this ami in your terraform.tfvars variable
• The OLD version is still available in branch fullcustom

Terraform-Splunk

1. Creates a poliy/role/instance profile to be able to download your splunk package from a specified s3 bucket/path
2. Creates an ELB pointing out to the elb search heads
3. Creates ( customisable number/ports/replication stuff )

• Search heads
• Cluster master
• Peered Indexers in an autoscaling group
• Deployment server ( clients will only be cluster master and search heads )

4. Creates Security Groups:

• All ports/protocols between splunk servers
• SSH and web access from a given admin cidr_block to all splunk servers
• TCP 80 from anywhere to ELB
• TCP port custom from ELB to search heads

#TODO:

• Add licence server
• A lot of stuff
