Create new GKE cluster using OCLI
The following document shows how to create a new GKE cluster using OCLI
Prerequisites
-
Install gcloud >= 2.50 and gke-gcloud-auth-plugin plugin.
-
You must have a GCP project and a user or serviceaccount having
admin
privileges. You can log in using the following command.gcloud config set project $PROJECT_ID # gcloud ADC login gcloud auth application-default login
-
Enable Service usage API in your project. You can use the below command or use the console for the same.
gcloud auth login \ && gcloud services enable serviceusage.googleapis.com --project=$PROJECT_ID
Suggestion
We highly recommend you to please go through the GCP Infrastructure requirements carefully.
Installing OCLI
- Download the binary using the below command.
curl -H 'Cache-Control: max-age=0' -s "https://releases.ocli.truefoundry.tech/binaries/ocli_$(curl -H 'Cache-Control: max-age=0' -s https://releases.ocli.truefoundry.tech/stable.txt)_darwin_arm64" -o ocli
curl -H 'Cache-Control: max-age=0' -s "https://releases.ocli.truefoundry.tech/binaries/ocli_$(curl -H 'Cache-Control: max-age=0' -s https://releases.ocli.truefoundry.tech/stable.txt)_darwin_amd64" -o ocli
curl -H 'Cache-Control: max-age=0' -s "https://releases.ocli.truefoundry.tech/binaries/ocli_$(curl -H 'Cache-Control: max-age=0' -s https://releases.ocli.truefoundry.tech/stable.txt)_linux_arm64" -o ocli
curl -H 'Cache-Control: max-age=0' -s "https://releases.ocli.truefoundry.tech/binaries/ocli_$(curl -H 'Cache-Control: max-age=0' -s https://releases.ocli.truefoundry.tech/stable.txt)_linux_amd64" -o ocli
- Make the binary executable and move it to
$PATH
sudo chmod +x ./ocli sudo mv ocli /usr/local/bin
- Confirm by running the command
ocli --version
Configuring input config file
- To create a new cluster, you would require your GCP
Project ID
,Region
, andNetwork
details - Run the following command to fill in the inputs interactively
ocli init-compute-plane
- For networking, there are two possible configurations:
- New network (Recommended) - This creates a new Virtual network for your new cluster.
- Existing network - You can enter your existing Virtual network.
- Once all the inputs are filled, an input config file with the name
tfy-config.yaml
would be generated in your current directory. We highly recommend you to once go through the generated config file and tally your inputs. You can also customize the inputs directly by editing the file. Below is the sample for the same:
aws: null
azure: null
binaries:
terraform:
binary_path: null
terragrunt:
binary_path: null
gcp:
cluster:
name: coolml
network:
existing: true
network_name: existing-vnet
pod_cidr: ""
service_cidr: ""
subnet_cidr: ""
subnet_id: projects/projectID/regions/us-east1/subnetworks/existing-vnet
project:
id: projectID
region:
availability_zones:
- us-east1-b
- us-east1-c
- us-east1-d
name: us-east1
tags: {}
provider: gcp
aws: null
azure: null
binaries:
terraform:
binary_path: null
terragrunt:
binary_path: null
gcp:
cluster:
name: coolml
network:
existing: false
network_name: ""
pod_cidr: 10.244.0.0/16
service_cidr: 10.255.0.0/16
subnet_cidr: 10.10.0.0/16
subnet_id: ""
project:
id: projectID
region:
availability_zones:
- us-west1-a
- us-west1-b
- us-west1-c
name: us-west1
tags: {}
provider: gcp
Create the cluster
Run the following command to create the GKE cluster.
ocli run --file tfy-config.yaml
This command may take around 30-45 minutes to complete.
Connecting the cluster
- Head over to the TrueFoundry platform and log in. If you haven't logged in, then you can sign up here.
- Once you have logged in, navigate to
Integrations
tab from the left panel and click onSetup Cluster
. - Give the name of the GKE cluster and select the cluster type as
GCP GKE Standard
. - Copy the resulting ocli command. This command installs the agent in your GKE cluster which will connect your cluster to the TrueFoundry control plane. The command looks similar to the following:
ocli connect-compute-plane --cloud gcp-gke-standard --control-plane-url https://coolml.truefoundry.tech \
--token xxxxxxx --tenant coolml
- Run the command from the current directory where your
tfy-config.yaml
is present.
Saving the output file
Once the above command finishes, save the output using the command below:
ocli output --file tfy-config.yaml > output.txt
