How to Deploy

Edit your preferences

Edit variables.tf file to customize application preferences like Github account, repo and owner, Load Balancer ports and cluster preferences.

# Customize the Cluster Name
variable "cluster_name" {
  description = "ECS Cluster Name"
  default     = "web-app"
}

# Customize your ECR Registry Name
variable "app_repository_name" {
  description = "ECR Repository Name"
  default     = "web-app"
}

###### APPLICATION OPTIONS  ######
variable "container_name" {
  description = "Container app name"
  default     = "micro-api"
}

Edit the Github preferences in the same file to specify infos like repo, owner or organization, branches e etc.

# Github Repository Owner
variable "git_repository_owner" {
  description = "Github Repository Owner"
  default     = "msfidelis"
}

# Github Repository Project Name
variable "git_repository_name" {
  description = "Project name on Github"
  default     = "micro-api"
}

# Default Branch
variable "git_repository_branch" {
  description = "Github Project Branch"
  default     = "master"
}

Edit Auto Scaling Metrics

# Number of containers
variable "desired_tasks" {
  description = "Number of containers desired to run app task"
  default     = 2
}

variable "min_tasks" {
  description = "Minimum"
  default     = 2
}

variable "max_tasks" {
  description = "Maximum"
  default     = 4
}

variable "cpu_to_scale_up" {
  description = "CPU % to Scale Up the number of containers"
  default     = 80
}

variable "cpu_to_scale_down" {
  description = "CPU % to Scale Down the number of containers"
  default     = 30
}
