How to upgrade the log-agent via Terraform

[lionelmace]

Partner has installed log-agent with this terraform module
https://github.com/terraform-ibm-modules/terraform-ibm-observability-agents/tree/main/modules/logs-agent

The log agent is currently in version 1.4 and needs to upgraded to version 1.5.1.

Questions:

• The agent does not let the use pass the version of the agent at installation time?
• Can the upgrade be performed by Terraform?

I got the answers...

since version 2.6.1 this module is using version 1.5.1 of the logs-agent helm chart:
https://github.com/terraform-ibm-modules/terraform-ibm-observability-agents/releases/tag/v2.6.1

Usually a parent module is used that references a version of the agents module. This would look similar to this:

module "observability_agents" {
  source                           = "terraform-ibm-modules/observability-agents/ibm"
  version                          = "X.X.X" # Replace "X.X.X" with a release version to lock into a specific release
  is_vpc_cluster                   = true # Change to false if target cluster is running on classic infrastructure
  cluster_id                       = "cluster id" # update this with your cluster id where the agents will be installed
  cluster_resource_group_id        = "resource group id" # update this with the Id of your IBM Cloud resource group
  cloud_monitoring_access_key      = "XXXXXXXX"
  cloud_monitoring_instance_region = "us-south"
  # Logs Agent variables
  logs_agent_trusted_profile  = "XXXXXXXX"
  cloud_logs_ingress_endpoint = "<cloud-logs-instance-guid>.ingress.us-south.logs.cloud.ibm.com"
  cloud_logs_ingress_port     = 443
}

With the version parameter you can control which version of the agents module is used. So this needs to be updated and applied again
