Guided setup 1: Deploy in a new VPC with Elastic Compute¶

Description ¶

This guided setup allows you to install a full Dataiku Cloud Stacks for GCP, including the ability to run workloads on Elastic Compute clusters powered by Kubernetes (using GKE).

At the end of this walkthrough, you’ll have:

A fully-managed DSS design node, with either a public IP or a private one
The ability to one-click create elastic compute clusters
The elastic compute clusters running with public IPs (and no NAT gateway overhead)

You need to have, as an administrator, the permissions to create service accounts in the project and to grant IAM rights to these service accounts. Said service accounts need not have permission to grant IAM rights, they’re only needed for the initial setup and required by the software during usage.

You need to have installed the Cloud SDK <https://cloud.google.com/sdk/docs/install> on a machine, and be able to run the gcloud command line assuming the same identity as in the console, and with the project set to the GCP project where the FM instance is to be deployed.

Steps ¶

Create a service account for your Fleet Manager instance ¶

In your Google cloud controls, go to your project, and to the “IAM & admin” section
In the “Service accounts” tab, click “Create service account”
Enter a name for your service account
Click on “Create and continue”
In the “Grant this service account access to the project (optional)” part of the Service account creation screen, select and add the following roles: “Service account user”, “Compute admin”, “DNS administrator”, “Cloud KMS Crypto operator”
Click on “Continue” then “Done”
In the list, take note of the “email” of the service account, this will be refered as fm-email
More permissions can be granted to the service account on the “IAM” tab, either by editing the service account line (with the pencil icon on the right) or by adding role assignments (with the “Add” button at the top)

Create a service account for your DSS instance ¶

In your Google cloud controls, go to your project, and to the “IAM & admin” section
In the “Service accounts” tab, click “Create service account”
Enter a name for your service account
Click on “Create and continue”
In the “Grant this service account access to the project (optional)” part of the Service account creation screen, select and add the following roles: “Service account user”, “Kubernetes engine admin”, “Secret Manager Secret Accessor”, “Compute viewer”, “Artifact Registry Create-on-Push Writer”
Click on “Continue” then “Done”
In the list, take note of the “email” of the service account, this will be refered as dss-email
More permissions can be granted to the service account on the “IAM” tab, either by editing the service account line (with the pencil icon on the right) or by adding role assignments (with the “Add” button at the top)

Ensure access to the container registry ¶

on a machine where Docker is installed, log into Google Cloud with a user or service account that has the “storage.buckets.create” permission, typically one that has “Storage admin”
tag and push some image to gcr.io (optionally eu.gcr.io and us.gcr.io if you plan to use them)

docker pull busybox
docker tag busybox gcr.io/<project-name>/busybox
docker push gcr.io/<project-name>/busybox

In your Google cloud controls, go to your project, and to the “Cloud Storage” section
locate the artifacts.<project-name>.appspot.com bucket, open it
in the “Permission” tab, click on “Add” a permission, then select dss-email as principal and “Storage Admin” as role, and “Save”

Create a VPC to host the fleet manager ¶

You’ll need 2 CIDR for the network:

one will be used for the network itself, and in fine for putting the VMs on the network. You can for example use “10.0.0.0/16”. This CIDR will be referred as network-cidr
one will be used to allow internal routing on the network, between the VMs but also between secondary IP ranges that might be created in the network. This CIDR thus needs to be larger than network-cidr, for example “10.0.0.0/8”. This CIDR will be referred as internal-cidr. Secondary ranges are used by GKE for pods and services (see GKE doc)

Then you can create a VPC network:

In your Google cloud controls, go to your project, and to the “VPC network” section
In the “VPC networks” tab, click “Create VPC network”
Enter a name for the network; this will be referred as fm-network
In the “Subnets” section, make sure “Custom” is selected and create one subnet
Enter a name for the subnet; this will be referred as fm-subnetwork
Enter a region for the subnet. The FM instance will be deployed in a zone of that region. This region will be referred as fm-region
For IPv4 range, enter the value chosen for network-cidr
Set “Private Google Access” to off
Click “Create”
Once the network is created, go to the “Firewall” tab
Click “Create firewall rule”
Set the name to “fm-network-external”
Select :
- “Network” -> fm-network
- “Direction” -> “Ingress”
- “Action” -> “Allow”
- “Targets” -> “All instances in the network”
- “Source filter” -> “IPv4 ranges”
- “Source IPv4 ranges” -> 0.0.0.0/0
- “Protocols and ports” -> “Specified protocols and ports”
  check “Tcp” and set the port to 22, 80, 443
Click “Create”
Again, click “Create firewall rule”
Set the name to “fm-network-internal”
Select :
- “Network” -> fm-network
- “Direction” -> “Ingress”
- “Action” -> “Allow”
- “Targets” -> “All instances in the network”
- “Source filter” -> “IPv4 ranges”
- “Source IPv4 ranges” -> the value chosen for internal-cidr
- “Protocols and ports” -> “Allow all”
Click “Create”

Deploy Fleet Manager ¶

Fetch the template files by running on the command line

gsutil cp gs://dataiku-cloudstacks/templates/fleet-manager/13.2.1/fleet-manager-instance.jinja .
gsutil cp gs://dataiku-cloudstacks/templates/fleet-manager/13.2.1/fleet-manager-instance.jinja.schema .

Start the deployment by running on the command line

gcloud deployment-manager deployments create <deployment-name> --template fleet-manager-instance.jinja --properties zone:<zone>,machineType:<machine-type>,network:<network>,subnetwork:<subnetwork>,serviceAccount:<fm-email>,allowedCIDR:<allowed-cidr>,username:<fm-username>,password:<fm-password>,sshKey:"<fm-authorized-key>",labels:key1=value1;key2=value2

where:

deployment-name is a name for your deployment in the GCP Deployment Manager
zone is the GCP zone where the resource should be deployed
machine-type is a GCE machine type like “n1-standard-4”
network is fm-network
subnetwork is fm-subnetwork
fm-email is the email of the service account for the FM instance that you created above
allowed-cidr is a CIDR of IP addresses that are allowed to connect to the FM instance
fm-username is a username for logging in to Fleet Manager
fm-password is a strong password for logging in to Fleet Manager
fm-authorized-key is a RSA public key for SSH logging in to the underlying Fleet Manager virtual machine

Additional options can be used in the above command:

networkProject: project of the network (default is the current project). If different from the current project, allowedCIDR has no effect
privateIpAddress: optional static private IP address for Fleet Manager
publicIpAddress: optional static public IP address for Fleet Manager. Specify an unused static external IP address available in the project. If you specify a static external IP address, it must live in the same region as the zone of the instance
dssServiceAccount: email of the service account the DSS instances are to run as
snapshot: optional snapshot to create the instance with. Can be “projects/{project}/global/snapshots/{snapshot}” or “global/snapshots/{snapshot}”
labels: optional semicolon-separated list of labels in key=value format to add to the resources that support them created by the deployment (e.g. key1=value1;key2=value2)

Wait for your deployment to complete

The deployment command will output the IP of the instance it spawned. This is the address at which your Cloud Stacks Fleet manager is deployed. Open a new tab to this address and wait for the login screen to appear.

Note

If re-deploying, or deploying after failure on a previous deployment of the template, you can also use gcloud deployment-manager deployments update ... instead of gcloud deployment-manager deployments create ...

The command-line version of the gcloud deployment-manager deployments create ... command can also be used with a config file. For example a config.yaml file with:

imports:
- path: fleet-manager-instance.jinja
  name: fleet-manager-instance
resources:
  - name: fleet-manager-instance
    type: fleet-manager-instance.jinja
    properties:
        zone: <zone>
        machineType: <machine-type>
        network: <network>
        subnetwork: <subnetwork>
        serviceAccount: <fm-email>
        allowedCIDR:< allowed-cidr>
        username: <fm-username>
        password: <fm-password>
        sshKey: "<fm-authorized-key>"
        labels: key1=value1;key2=value2

yields the same deployment as the command above with

gcloud deployment-manager deployments create <deployment-name> --config=config.yaml

Start your first DSS ¶

Log into Fleet Manager with the login and the password you previously entered
In “Cloud Setup”, click on “Edit”, set “License mode” to “Manually entered”, click on “Enter license” and enter your Dataiku license. Click on “Done” then on “Save”
Refresh the page in your browser
In “Fleet Blueprints”, click on “Deploy Elastic Design”
Give a name to your new fleet, this will be refered as fleet-name
In “Instance service account”, enter the dss-email
Click on “Deploy”
Go to “Virtual Networks”, select the “Virtual network for fleet fleet name”
In the settings, in “Network tags”, put “tag-<deployment-name>”, where <deployment-name> is the name used for the deployment in the previous commands, and Save
Go to “Instances > All”, click on the design node
Click “Provision”
Wait for your DSS instance to be ready
Click on the Retrieve button under “Retrieve password” and write down the password
Click on “Go to DSS”
Login with “admin” as the login, and the password you just retrieved

You can now start using DSS

(Optional) Start your first Elastic compute cluster ¶

Deploy your Elastic Compute cluster ¶

In DSS, go to Administration > Clusters
Click on “Create GKE cluster”, give it a name
In “Connection”, check it is set to “Manually defined”
In section “Networking”, check that “Inherit DSS host settings” is checked.
In section “Networking”, check that “Make cluster VPC-native” is checked, and fill “Pod IP range” and “Service IP range”. Both ranges should be within the internal-cidr used when deploying the FM template, and non-overlapping with network-cidr. If network-cidr is x.y.0.0/16 and internal-cidr is x.0.0.0/8 then you can leave GKE to create automatically the ranges.
In “Cluster Nodes”, Click on “+ Add a preset”
Update “Machine type” and “Disk size” as you see fit
Tick the “Enable nodes autoscaling” box
In “Advanced options”, set “Service account type” to “Same as DSS host”
Click on “Start”
Wait for your cluster to be available
In Settings, go to “Containerized execution”, and in “Default cluster”, select the cluster you just created.
In the “gke-default” configuration, adjust the “Image registry url” if needed
Click on “Save” then “Push base images”. When finished, click on “(Re)Install Jupyter kernels”.
In a project, you can now use containerized execution for any activity, using the containerized config you created
