This repos contains a complete AWS EC2 instance creation with Docker installation, using terraform to provision EC2 instances on AWS, and Ansible playbooks to install docker.
- image-flavor: type of instance you want to create (for example "t2.micro") It is not possible at this time to have a different size of instance per type of server.
- key-pair: name of the public key you declared in AWS to connect to your insances
- aws-region: region of the AWS instance (for example "eu-west-1")
- tag-name: name of the instance
- tag-cpaccount: another tag (if you don't need it, remove it from terraform .tf)
- aws-ssh-key: Path to your private key (variable named key-pair) you attached to the instances.

% brew install ansible
Download the appropriate package from https://www.terraform.io/downloads.html and install the binary :
% sudo mv ~/Downloads/terraform /usr/local/bin
AWS role secrets
Copy aws-keys-example.sh to aws-keys.sh and replace YOUR_KEY_ID and YOUR_SECRET_KEY strings with your aws key id and access secret.
export AWS_ACCESS_KEY_ID=__YOUR_KEY_ID__ export AWS_SECRET_ACCESS_KEY=__YOUR_SECRET_KEY__
% source aws-keys.sh
Copy terraform-example.tfvars into terraform.tfvars and set variables according to your configuration. In this example, the ami correspond to a ubuntu 16.04. Set the key pair that is provisioned in your aws account. It will be used by ansible to configure your instances.
ami="ami-785db401" image-flavor="t2.micro" key-pair="your-key-name" region="eu-west-1" tag-name="optionnal-aws-intance-name-tag" tag-cpaccount="another-optionnal-tag"
Initialize terraform providers
% terraform init Initializing provider plugins... - Checking for available provider plugins on https://releases.hashicorp.com... - Downloading plugin for provider "null" (1.0.0)... The following providers do not have any version constraints in configuration, so the latest version was installed. To prevent automatic upgrades to new major versions that may contain breaking changes, it is recommended to add version = "..." constraints to the corresponding provider blocks in configuration, with the constraint strings suggested below. * provider.aws: version = "~> 1.5" * provider.null: version = "~> 1.0" Terraform has been successfully initialized! You may now begin working with Terraform. Try running "terraform plan" to see any changes that are required for your infrastructure. All Terraform commands should now work. If you ever set or change modules or backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so if necessary.
This will create a local .terraform directory with required plugins:
.terraform └── plugins └── darwin_amd64 ├── lock.json ├── terraform-provider-aws_v1.5.0_x4 └── terraform-provider-null_v1.0.0_x4
Launch the plan
Check the terraform execution with:
% terraform plan
If everything is ok:
% terraform apply
