SLURM Terraform practice

With this project you can build a custom Centos image with Packer, upload it to Yandex cloud, and deploy an infrastructure based on this image.

Cd to packer dir.

First export environment variables with Yandex credentials for Packer. For this you need the YC utility installed and set up. You also got to have a default subnet default-ru-central1-a for the build process to be successful. Alternatively you may specify any existing subnet name in pkr_env_vars.sh file.

source ./pkr_env_vars.sh

Build an image with Packer and upload it to Yandex cloud. You may specify any numeric tag:

packer build -var "image_tag=1" .

Now cd to terraform dir.

Export environment variables with Yandex credentials for Terraform. You need the YC utility installed and set up:

source ./tf_env_vars.sh

You may want to correct variables in var.auto.tfvars file to your liking.

Set up Terraform:

terraform init

Run Terraform:

terraform apply -auto-approve

You may specify image name, image tag and amount of VMs like this:

terraform apply -auto-approve \
                -var="image_name=my-name" \
                -var="image_tag=my-tag" \
                -var="vm_count=4"
