Deploy steps

1. Clone repository and get to deploy folder

git clone https://github.com/zebrunner/e3s-terraform-deploy.git && cd ./e3s-terraform-deploy/deploy

2. Create and configure terraform.tfvars file

Mandatory vars:

• environment - Value type: string. Default value: None. Determines prefix in name for all e3s aws resources.
• region - Values type: string. Default value: None. Aws region in which all e3s resources will be created.
• e3s_key_name - Value type: string. Default value: None. Aws key name, that will be attached to e3s-server instance.
• bucket - Value type: object. Default value: None. Describes whether to create a new s3 bucket, or use an existing one. Fields:
• • exists - Value type: boolean.
• • name - Value type: string.
• • region- Value type: string.

Optional vars:

• cert - Value type: string. Default value: None. Certificate arn to attach to listener. If none provided, load balancer will support only http protocol.
• e3s_server_instance_type - Value type: string. Default value: m5n.large. Instance type for e3s-server.
• allow_agent_ssh - Value type: boolean. Default value: false. Allows ssh connection to agent instances by newly created key name only from e3s-server instance.
• enable_cloudwatch - Value type: boolean. Default value: false. Enables tasks logs display at aws ecs console.
• data_layer_remote - Value type: boolean. Default value: true. Determines whether to create rds and elasticache services in aws cloud or use local ones instead.
• nat - Value type: boolean. Default value: false. Determines whether to create private subnets and provide internet connection by nat gateways.
• max_az_number - Value type: number. Default value: 3. Determines number of availability zones to use in current region
• profile - Value type: string. Default value: None. Aws profile to use in terraform provider.
• remote_db - Value type: object. Default value:

{
    username = "postgres"
    pass     = "postgres"
}

RDS service credentials configuration. Ignored if data_layer_remote is set to false. Fields:

• • username - Value type: string.
• • pass - Value type: string.
• instance_types = Value type: object array. Default value:

[
    {
        weight        = 1
        instance_type = "c5a.4xlarge"
    },
    {
        weight        = 2
        instance_type = "c5a.8xlarge"
    }
]

Determines autoscaling group instance types and corresponding weights. Fields:

• • weight - Value type: number.
• • instance_type - Value type: string.
• spot_price - Value type: object. Default value: None. Determines spot price per 1 weight in autoscaling group. If none is specified on-demand instances are used instead. Fields:
• • linux - Value type: string.
• • windows - Value type: string.
• zebrunner - Value type: object. Default value: None. Zebrunner reporting integration configuration. Fields:
• • host - Value type: string.
• • user - Value type: string.
• • pass - Value type: string.

3. Create and configure config.{service}.tfbackend file.

Example of s3 backend state configure (config.s3.tfbackend file):

bucket         = "{state_bucket_name}"
key            = "{state_bucket_key}"
region         = "{state_bucket_region}"
dynamodb_table = "{state_dynamodb_table}"
encrypt        = true

4. Init terraform providers

terraform init -backend-config=config.{service}.tfbackend

5. Deploy

terraform apply

6. [Optional] User policices.

For user's use could be created e3s-manage and e3s-monitor policies.
