WasmCloud on ECS Fargate

Infrastructure:

• 1 NATS
  • Public Load Balancer exposing port 4222 ( wash access )
  • Ephemeral Volume for Jetstream
• 1 wasmCloud wadm
• 1 wasmCloud worker instance
  • Autoscaling based on CPU usage
  • Capacity: 1 min, 1 max ( configurable )
• 1 wasmCloud ingress instance
  • Public Load Balancer exposing port 80 ( http access )

Setup

Create a file named terraform.tvfars with the following content:

aws_region              = "us-east-2"

# If using aws cli profile (SSO), set it here
aws_profile             = "enterprise-dev"

# CIDRs for wash access ( default none )
nats_allowed_cidrs      = ["45.74.99.13/32"]

# CIDRs for http access ( default 0.0.0/0 )
wasmcloud_allowed_cidrs = ["45.74.99.13/32"]

Apply the terraform configuration:

terraform init

terraform apply

wash access

export WASMCLOUD_CTL_HOST="$(terraform output -raw nats_lb)"

wash get inventory

external access

Once wash is setup, deploy a sample application:

wash app deploy ./hello-world-wadm.yaml

Access the application:

export WASMCLOUD_LB="$(terraform output -raw wasmcloud_public_lb)"
curl -i http://$WASMCLOUD_LB
