#initialize(additional_args: nil, aws_api_retry_attempts: nil, dns_cluster_ip: nil, docker_config_json: nil, enable_docker_bridge: nil, kubelet_extra_args: nil, use_max_pods: nil) ⇒ BootstrapOptions

Returns a new instance of BootstrapOptions.

Parameters:

  • additional_args (String, nil) (defaults to: nil) —

    Additional command line arguments to pass to the /etc/eks/bootstrap.sh command.

  • aws_api_retry_attempts (Numeric, nil) (defaults to: nil) —

    Number of retry attempts for AWS API call (DescribeCluster).

  • dns_cluster_ip (String, nil) (defaults to: nil) —

    Overrides the IP address to use for DNS queries within the cluster.

  • docker_config_json (String, nil) (defaults to: nil) —

    The contents of the /etc/docker/daemon.json file. Useful if you want a custom config differing from the default one in the EKS AMI.

  • enable_docker_bridge (Boolean, nil) (defaults to: nil) —

    Restores the docker default bridge network.

  • kubelet_extra_args (String, nil) (defaults to: nil) —

    Extra arguments to add to the kubelet. Useful for adding labels or taints.

  • use_max_pods (Boolean, nil) (defaults to: nil) —

    Sets --max-pods for the kubelet based on the capacity of the EC2 instance.
