Install Determined#

This user guide describes how to deploy a Determined cluster on Amazon Web Services (AWS). The det deploy tool makes it easy to create and install these resources. If you would rather create the cluster manually, see the Manual Deployment section below.

For more information about using Determined on AWS, see the Deploy on AWS topic guide.

`det deploy` tool#

The det deploy tool is provided by the determined Python package. It uses AWS CloudFormation to automatically deploy and configure a Determined cluster. CloudFormation builds the necessary components for Determined into a single CloudFormation stack.

Requirements#

Either AWS credentials or an IAM role with permissions to access AWS CloudFormation APIs. See the AWS Documentation for information on how to use AWS credentials.
An AWS EC2 Keypair.

You may also want to increase the EC2 instance limits on your account — the default instance limits on GPU instances are zero. The default configuration for det deploy can result in launching up to 5 g4dn.metal instances (which have 94 vCPUs each), which would exceed the default quota. AWS instance limits can be increased by submitting a request to the AWS Support Center.

Installation#

det command line tool can be installed using pip:

pip install determined

Note

The command, pip install determined, installs the determined library which includes the Determined command-line interface (CLI).

Deploying#

The basic command to deploy a cluster is as follows:

det deploy aws up --cluster-id CLUSTER_ID --keypair KEYPAIR_NAME

CLUSTER_ID is an arbitrary unique ID for the new cluster. We recommend choosing a cluster ID that is memorable and helps identify what the cluster is being used for. The cluster ID will be used as the AWS CloudFormation stack name.

KEYPAIR_NAME is the name of the AWS EC2 key pair to use when provisioning the cluster. If the AWS CLI is installed on your machine, you can get a list of the available keypair names by running aws ec2 describe-key-pairs.

The deployment process may take 5–10 minutes. When it completes, summary information about the newly deployed cluster will be printed, including the URL of the Determined master.

Deployment Types#

det deploy supports multiple deployment types to work with different security needs. The deployment type can be specified using the --deployment-type argument (e.g., det deploy aws --deployment-type secure).

simple: The simple deployment provides an easy way to deploy a Determined cluster in AWS. This creates the master instance in the default subnet for the account.
efs: The EFS deployment creates an EFS file system and a Determined cluster into a separate VPC. The EFS drive attaches to agent instances at /mnt/efs. This path is automatically bind-mounted into the task containers.
fsx: The FSX deployment creates a Lustre FSx file system and a Determined cluster into a separate VPC. The FSx drive attaches to agent instances at /mnt/fsx. This path is automatically bind-mounted into the task containers.
secure: The secure deployment creates resources to lock down the Determined cluster. These resources are:
- A VPC with a public and private subnet
- A NAT gateway for the private subnet to make outbound connections
- An S3 VPC gateway so the private subnet can access S3
- A bastion instance in the public subnet
- A master instance in the private subnet

Printing the default `master.yaml` template#

det deploy aws dump-master-config-template

Custom master.yaml templates#

Advanced users who require a deep customization of master settings (i.e., the master.yaml config file) can use the master.yaml templating feature. Since det deploy aws fills in plenty of infrastructure-related values such as VPC subnet ids or IAM instance profile roles, we provide a simplified templating solution, similar to helm charts in kubernetes. Template language is based on golang templates, and includes sprig helper library and toYaml serialization helper.

Example workflow:

Get the default template using

det deploy aws dump-master-config-template > /path/to/master.yaml.tmpl

Customize the template as you see fit by editing it in any text editor. For example, let’s say a user wants to utilize (default) g4dn.metal 8-GPU instances for the default compute pool, but they also often run single-GPU notebook jobs, for which a single g4dn.xlarge instance would be perfect. So, you want to add a third pool compute-pool-solo with a customized instance type.

Start with the default template, and find the resource_pools section:

resource_pools:
  - pool_name: aux-pool
    max_aux_containers_per_agent: {{ .resource_pools.pools.aux_pool.max_aux_containers_per_agent }}
    provider:
      instance_type: {{ .resource_pools.pools.aux_pool.instance_type }}
      {{- toYaml .resource_pools.aws | nindent 6}}

  - pool_name: compute-pool
    max_aux_containers_per_agent: 0
    provider:
      instance_type: {{ .resource_pools.pools.compute_pool.instance_type }}
      cpu_slots_allowed: true
      {{- toYaml .resource_pools.aws | nindent 6}}

Then, append a new section:

- pool_name: compute-pool-solo
  max_aux_containers_per_agent: 0
  provider:
    instance_type: g4dn.xlarge
    {{- toYaml .resource_pools.aws | nindent 6}}

Use the new template:

det deploy aws <ALL PREVIOUSLY USED FLAGS> --master-config-template-path /path/to/edited/master.yaml.tmpl

All set! Check the Cluster page in WebUI to ensure your cluster has 3 resource pools. In case of errors, ssh to the master instance as instructed by det deploy aws output, and check /var/log/cloud-init-output.log or sudo docker logs determined-master.

Modifying a Deployment#

To modify an already deployed cluster you have a few options:

If what you’d like to change is provided as a det deploy CLI option, you can re-deploy the cluster using det deploy. Use the same full det deploy command as on cluster creation, but update the options as necessary, while keeping the cluster-id the same. det deploy will then find the existing cluster, take it down, and spin up a new one with the updated options.
If you want more control over the master configuration while minimizing downtime, you can SSH into the master instance using the private key from the keypair that was used to provision the cluster. Once you’re successfully connected, you can modify master.yaml under /usr/local/determined/etc and restart the master Docker container for your changes to take effect:
```
sudo docker container restart determined-master
```
For example, if you want to add or modify resource pools you can edit the master configuration file at /usr/local/determined/etc/master.yaml and add a new resource pool entry.

Manual Deployment#

Database#

Determined requires a PostgreSQL-compatible database, such as AWS Aurora. Configure the cluster to use the database by including the database information in master.yaml. Make sure to create a database before running the Determined cluster (e.g., CREATE DATABASE <database-name>).

Example master.yaml snippet:

db:
  user: "${database-user}"
  password: "${database-password}"
  host: "${database-hostname}"
  port: 5432
  name: "${database-name}"

Security Groups#

VPC Security Groups provide a set of rules for inbound and outbound network traffic. The requirements for a Determined cluster are:

Master#

Egress on all ports to agent security group
Egress on all ports to the Internet
Ingress on port 8080 for access the Determined WebUI and REST APIs
Ingress on port 22 for SSH (recommended but not required)
Ingress on all ports from agent security group

IAM Roles#

IAM roles comprise IAM policies, which provide access to AWS APIs such as the EC2 or S3 API. The IAM policies needed for the Determined cluster are:

Master#

Allow EC2 to assume role
Allow EC2 to describe, create, and terminate instances with agent role
Allow EC2 to describe, create, and terminate spot instance requests (only required if using spot instances)

Master Node#

The master node should be deployed on an EC2 instance with at least 4 CPUs (Intel Broadwell or later), 8GB of RAM, and 200GB of disk storage. This roughly corresponds to an EC2 t2.large instance or better. The AMI should be the default Ubuntu 18.04 AMI.

To run Determined:

Install Docker and create the determined Docker network.

apt-get remove docker docker-engine docker.io containerd runc
apt-get update
apt-get install -y \
  apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"
apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io

docker network create determined

Configure the cluster with master.yaml. See Step 7 - Configure the Cluster for more information.

Notes:

image_id should be the latest Determined agent AMI.
instance_type should be any p2 or p3 EC2 instance type.
For more information about resource pools, see Resource Pools

Warning

An important assumption of Determined with dynamic agents is that any EC2 instances with the configured tag_key:tag_value pair are managed by the Determined master. This pair should be unique to your Determined installation. If it is not, Determined may inadvertently manage your non-Determined EC2 instances.

If using spot instances, Determined also assumes that any EC2 spot instance requests with the configured tag_key:tag_value pair are managed by the Determined master.
