The multi-cloud kubernetes provisioner component of the Cross-Cloud CI project.
A Kubernetes provisioner supporting multiple clouds (eg. AWS, Azure, Google, Equinix Metal) which
- Creates K8s clusters on cloud providers
- Supplies conformance validated Kubernetes end-points for each cloud provider with cloud specific features enabled
You have to have a working Docker environment
Note: 147.75.69.23 is the IP address of the DNS server for Cross Cloud deployed Nodes. Should you wish to be able to reach your Nodes by name from outside the cluster, that IP needs to be in your /etc/resolv.conf but it is not a delegating resolver, so it shouldn't be the only nameserver in your resolv.conf.
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=$AWS_DEFAULT_REGION \
-ti registry.cncf.ci/cncf/cross-cloud/provisioning:productionPre-reqs: Project created on Google Cloud (eg. test-cncf-cross-cloud)
Google Cloud JSON configuration file for authentication. (This file is downloaded directly from the Google Developers Console)
- Log into the Google Developers Console and select a project.
- The API Manager view should be selected, click on "Credentials" on the left, then "Create credentials," and finally "Service account key."
- Select "Compute Engine default service account" in the "Service account" dropdown, and select "JSON" as the key type.
- Clicking "Create" will download your credentials.
- Rename this file to credentials-gce.json and move to your home directory (~/credentials-gce.json)
Google Project ID
- Log into the Google Developers Console to be sent to the Google API library page screen
- Click the
Select a projectdrop-down in the upper left - Copy the Project ID for the desired project from the window that shows Eg. test-cncf-cross-cloud
Run the following to provision a Kubernetes cluster on GCE:
export GOOGLE_CREDENTIALS=$(cat ~/credentials-gce.json)
docker run \
-v /tmp/data:/cncf/data \
-e NAME=cross-cloud \
-e CLOUD=gce \
-e COMMAND=deploy \

-e GOOGLE_PROJECT=test-cncf-cross-cloud \
-e GOOGLE_CREDENTIALS="${GOOGLE_CREDENTIALS}" \
-ti registry.cncf.ci/cncf/cross-cloud/provisioning:productionYou 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 \

-ti registry.cncf.ci/cncf/cross-cloud/provisioning:productionThe vSphere provider requires vSphere host and credential information, as well as credentials for the linked AWS account:
Run the following to provision a vSphere cluster:
docker run \
--rm \
--dns 147.75.69.23 --dns 8.8.8.8 \
-v $(pwd)/data:/cncf/data \
-e NAME=cross-cloud \

-e VSPHERE_AWS_REGION=$VSPHERE_AWS_REGION \
-ti registry.cncf.ci/cncf/cross-cloud/provisioning:ci-stable-v0-2-0Packet.net requires an auth token and a project id.
To deploy to equinix metal:
docker run \
-v /tmp/data:/cncf/data \
--dns 147.75.69.23 --dns 8.8.8.8 \
-e NAME=cross-cloud \
-e CLOUD=packet \

-e PACKET_AUTH_TOKEN=${PACKET_AUTH_TOKEN} \
-e TF_VAR_packet_project_id=${PACKET_PROJECT_ID} \
-ti registry.cncf.ci/cncf/cross-cloud/provisioning:productionTo destroy your cluster in packet:
docker run \
-v /tmp/data:/cncf/data \
--dns 147.75.69.23 --dns 8.8.8.8 \
-e NAME=cross-cloud \
-e CLOUD=packet \
