Cross-cloud - multi-cloud provisioner

The multi-cloud kubernetes provisioner component of the Cross-Cloud CI project.

What is Cross-cloud?

A Kubernetes provisioner supporting multiple clouds (eg. AWS, Azure, Google, Packet) which

  • Creates K8s clusters on cloud providers
  • Supplies conformance validated Kubernetes end-points for each cloud provider with cloud specific features enabled

How to Use Cross-cloud

You have to have a working Docker environment

Quick start for AWS

Pre-reqs: IAM User with the following Permissions:

  • AmazonEC2FullAccess
  • AmazonS3FullAccess
  • AmazonRoute53DomainsFullAccess
  • AmazonRoute53FullAccess
  • IAMFullAccess
  • IAMUserChangePassword

AWS credentials

export AWS_ACCESS_KEY_ID="YOUR_AWS_KEY_ID"
export AWS_SECRET_ACCESS_KEY="YOUR_AWS_SECRET_KEY"
export AWS_DEFAULT_REGION=”YOUR_AWS_DEFAULT_REGION” # eg. ap-southeast-2

Run the following to provision a Kubernetes cluster on AWS:

docker run \
  -v /tmp/data:/cncf/data \
  -e NAME=cross-cloud
  -e CLOUD=aws    \
  -e COMMAND=deploy \
  -e BACKEND=file  \ 
  -e AWS_ACCESS_KEY_ID= $AWS_ACCESS_KEY_ID    \
  -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY    \
  -e AWS_DEFAULT_REGION=$AWS_DEFAULT_REGION    \
  -ti registry.cncf.ci/cncf/cross-cloud/provisioning:production
Quick start for GCE

Pre-reqs: Project created on Google Cloud (eg. test-cncf-cross-cloud)

Google Cloud JSON configuration file for authentication. (This file is downloaded directly from the Google Developers Console)

  1. Log into the Google Developers Console and select a project.
  2. The API Manager view should be selected, click on "Credentials" on the left, then "Create credentials," and finally "Service account key."
  3. Select "Compute Engine default service account" in the "Service account" dropdown, and select "JSON" as the key type.
  4. Clicking "Create" will download your credentials.
  5. Rename this file to credentials-gce.json and move to your home directory (~/credentials-gce.json)

Google Project ID

  1. Log into the Google Developers Console to be sent to the Google API library page screen
  2. Click the Select a project drop-down in the upper left
  3. Copy the Project ID for the desired project from the window that shows Eg. test-cncf-cross-cloud

Run the following to provision a Kubernetes cluster on GCE:

export GOOGLE_CREDENTIALS=$(cat ~/credentials-gce.json)
docker run \
  -v /tmp/data:/cncf/data  \
  -e NAME=cross-cloud  \
  -e CLOUD=gce    \
  -e COMMAND=deploy  \
  -e BACKEND=file  \ 
  -e GOOGLE_REGION=us-central1    \
  -e GOOGLE_PROJECT=test-cncf-cross-cloud  \
  -e GOOGLE_CREDENTIALS=”${GOOGLE_CREDENTIALS}”
  -ti registry.cncf.ci/cncf/cross-cloud/provisioning:production
Quick start for OpenStack

You will need a full set of credentials for an OpenStack cloud, including authentication endpoint.

Run the following to provision an OpenStack cluster:

docker run \
  -v $(pwd)/data:/cncf/data \
  -e NAME=cross-cloud \
  -e CLOUD=openstack \
  -e COMMAND=deploy \
  -e BACKEND=file \
  -e TF_VAR_os_auth_url=$OS_AUTH_URL \
  -e TF_VAR_os_region_name=$OS_REGION_NAME \
  -e TF_VAR_os_user_domain_name=$OS_USER_DOMAIN_NAME \
  -e TF_VAR_os_username=$OS_USERNAME \
  -e TF_VAR_os_project_name=$OS_PROJECT_NAME \
  -e TF_VAR_os_password=$OS_PASSWORD \
  -ti registry.cncf.ci/cncf/cross-cloud/provisioning:production

General usage and configuration

Minimum required configuration to use Cross-cloud to deploy a Kubernetes cluster on Cloud X.

docker run \
  -v /tmp/data:/cncf/data \
  -e NAME=cross-cloud
  -e CLOUD=<aws|gke|gce|openstack|packet>    \
  -e COMMAND=<deploy|destory> \
  -e BACKEND=<file|s3>  \ 
  <CLOUD_SPECIFIC_OPTIONS>
  <KUBERNETES_CLUSTER_OPTIONS>
  -ti registry.cncf.ci/cncf/cross-cloud/provisioning:production

Common Options

  • -e CLOUD=<aws|gke|gce|openstack|packet> # Choose the cloud provider. Then add the appropriate cloud specific options below.
  • -e COMMAND=<deploy|destory>
  • -e BACKEND=<file|s3> # File will store the Terraform State file to Disk / S3 will store the Terraform Statefile to a AWS s3 Bucket
