BogoToBogo Create and attach a additional drive. Terraform import Ec2 instance. You can also leverage the interesting EC2 User Data feature using Terraform. You signed in with another tab or window. As we have crossed all the sections of basic and prerequisites. If you’re new to the blog I highly recommend the start here page as the best possible starting point! This can be used to run a configuration management tool, bootstrap into a cluster, etc. You will: use the templatefile function to create a user_data script to dynamically configure an EC2 instance with resource information from your configuration. Hashicorp Terraform. lets create an ec2 instance manually using aws console You can also leverage the interesting EC2 User Data feature using Terraform. If you want to see the repository it is located in click here.. Use this data source to get IDs or IPs of Amazon EC2 instances to be referenced elsewhere, e.g. Hashicorp Vault. Reload to refresh your session. So let’s start writing your .tf file: Terraform code can be written in any text editor and save the file with “.tf” extension. ), File sharing between host and container (docker run -d -p -v), Linking containers and volume for datastore, Dockerfile -
