HOW TO USE

• DONT use the root user, its recommended to explore the IAM roles and delegate the specific needed roles to a new user account
• you can store the AWS_SECRET_ACCESS_KEY and AWS_ACCESS_KEY_ID as Terraform variables! but i stored the required credentials in ~/.bashrc file

export AWS_SECRET_ACCESS_KEY=""
export AWS_ACCESS_KEY_ID=""
alias tf='terraform' # for more easy use

• Clone this repo

git clone https://github.com/ahaffar/terraform_ecs.git
cd terraform-ecs

• Change the required values in aws_variables.tf file to reflect your specific settings such as SSH_KEY, CLUSTER_NAME ..
• RUN terraform plan to check the config
• RUN terraform apply
• Enjoy!
