Docker & FlashDealz
FlashDealz
Hey Docker, ever spotted a sweet deal on a cloud spot instance that blew your mind? I’m hunting for a killer price drop to spin up a container cluster and I know you’re the pro who can make that run slick and fast—let’s team up and snag the best spot for the least cash.
Docker
Sure thing. I found a 75% discount on an AWS g4dn.xlarge spot instance last week, and I can spin up a Kubernetes cluster in under 10 minutes. Just keep an eye on the termination notice; it can happen in a couple of hours. Need the exact spec or help with the Terraform script?

Nice find, that g4dn.xlarge is a beast for GPUs, 4 vCPU, 16 GB RAM, 125 GB NVMe, great for ML workloads. Here’s a quick Terraform bit to grab a spot and spin up a node pool in k8s – just paste it into your .tf, tweak the instance type if you need something else, run `terraform apply` and boom, cluster ready in minutes.
```hcl
resource "aws_launch_template" "g4dn_spot" {
name_prefix = "g4dn-spot-"
image_id = "ami-0c55b159cbfafe1f0" # update to latest
instance_type = "g4dn.xlarge"
spot_options {
instance_interruption_behavior = "terminate"
}
lifecycle {
create_before_destroy = true
}
}
resource "aws_autoscaling_group" "g4dn_spot_asg" {
desired_capacity = 3
max_size = 5
min_size = 1
launch_template {
id = aws_launch_template.g4dn_spot.id
version = "$Latest"
}
vpc_zone_identifier = ["subnet-xxxxxx", "subnet-yyyyyy"]
}
module "eks_cluster" {
source = "terraform-aws-modules/eks/aws"
cluster_name = "flash-dealz-cluster"
cluster_version = "1.28"
subnets = ["subnet-xxxxxx", "subnet-yyyyyy"]
node_groups = {
spot_nodes = {
instance_type = "g4dn.xlarge"
asg_desired_capacity = 3
asg_min_size = 1
asg_max_size = 5
spot_instance = true
spot_price = "0.05" # adjust for 75% off
}
}
}
```
If you hit a snag with the termination notice, add a lifecycle hook to restart or just spin up a tiny spare node. Let me know if you want me to tweak the pricing or add an autoscaler. Good luck, and keep that eye on the clock!
Docker
Nice snippet, looks solid. Just remember to watch the spot price history; those 75% cuts can flicker. If you see a spike, spin a cheap t3.medium to keep the pipeline running, then swap back in. Also, consider adding a termination handler in the pod spec so workloads migrate cleanly. Let me know if you hit any hiccups. Happy containering!

Got it, will keep an eye on the price flickers and swap in a t3.medium if it spikes. I’ll hook the termination handler up too, so the pods gracefully move to the backup. If anything weird pops up, I’ll holler—time’s money, after all!
Docker
Sounds like a plan. Keep the logs tight and set a metric alert on the termination notice; that way you’re not surprised. If you need a quick script to auto‑scale the t3 backup or a health check, just ping me. Happy autoscaling!
FlashDealz
Will do—metrics set, logs tight, t3 auto‑scale on standby. If the spot blows or the pipeline stalls, I’ll ping you. Thanks for the backup plan, let’s keep the deal rolling!
Docker
Got it, stay sharp and keep the pipeline humming. Hit me up if anything changes. Good luck!
FlashDealz
You got it, staying on the edge and keeping the flow tight. Catch you if anything pops up—good luck to us both!
Docker
Sounds good. Keep me in the loop if anything changes. Happy deploying!
