You can create a Camunda Cloud Account here: https://accounts.cloud.camunda.io/signup
Then you need to go to <YOUR USER>(Top right corner) -> Organization Settings -> Cloud Management API
and Create a new client. You need to copy and save the Client Id and the Secret Id from that client.
You need to export the following variables for this command to interact with a Camunda Cloud Account:
- export CC_CLIENT_ID=<YOUR CLIENT ID>
- export CC_CLIENT_SECRET=<YOUR CLIENT SECRET>
Available Commands:
# List all clusters
cc-ctl clusters get --all
# Get cluster from id
cc-ctl clusters get --id <cluster_id>
# Get cluster from name
cc-ctl clusters get --name <cluster_name>
# Delete cluster from id
cc-ctl clusters delete --id <cluster_id>
# Delete cluster from name
cc-ctl clusters delete --name <cluster_name>
# Create cluster from default configuration
cc-ctl clusters create --default --name <cluster_name>`,
