nodebalancer

Manage a Linode NodeBalancer.

Examples

- name: Create a Linode NodeBalancer
  linode.cloud.nodebalancer:
    label: my-loadbalancer
    region: us-east
    tags: [ prod-env ]
    state: present
    configs:
      - port: 80
        protocol: http
        algorithm: roundrobin
        nodes:
          - label: node1
            address: 0.0.0.0:80
- name: Delete the NodeBalancer
  linode.cloud.nodebalancer:
    label: my-loadbalancer
    region: us-east
    state: absent

Parameters

Field Type Required Description
label str Required The unique label to give this NodeBalancer.
state str Required The desired state of the target. (Choices: present, absent)
client_conn_throttle int Optional Throttle connections per second. Set to 0 (zero) to disable throttling. (Updatable)
region str Optional The ID of the Region to create this NodeBalancer in.
configs (sub-options) list Optional A list of configs to apply to the NodeBalancer. (Updatable)

configs

Field Type Required Description
algorithm str Optional What algorithm this NodeBalancer should use for routing traffic to backends. (Choices: roundrobin, leastconn, source; Updatable)
check str Optional The type of check to perform against backends to ensure they are serving requests. (Choices: none, connection, http, http_body; Updatable)
check_attempts int Optional How many times to attempt a check before considering a backend to be down. (Updatable)
check_body str Optional This value must be present in the response body of the check in order for it to pass. If this value is not present in the response body of a check request, the backend is considered to be down. (Updatable)
check_interval int Optional How often, in seconds, to check that backends are up and serving requests. (Updatable)
check_passive bool Optional If true, any response from this backend with a 5xx status code will be enough for it to be considered unhealthy and taken out of rotation. (Updatable)
check_path str Optional The URL path to check on each backend. If the backend does not respond to this request it is considered to be down. (Updatable)
check_timeout int Optional How long, in seconds, to wait for a check attempt before considering it failed. (Updatable)
cipher_suite str Optional What ciphers to use for SSL connections served by this NodeBalancer. (Choices: recommended, legacy; Default: recommended; Updatable)
port int Optional The port this Config is for. (Updatable)
protocol str Optional The protocol this port is configured to serve. (Choices: http, https, tcp; Updatable)
proxy_protocol str Optional ProxyProtocol is a TCP extension that sends initial TCP connection information such as source/destination IPs and ports to backend devices. (Choices: none, v1, v2; Updatable)
recreate bool Optional If true, the config will be forcibly recreated on every run. This is useful for updates to redacted fields (ssl_cert, ssl_key) (Default: False)
ssl_cert str Optional The PEM-formatted public SSL certificate (or the combined PEM-formatted SSL certificate and Certificate Authority chain) that should be served on this NodeBalancerConfig’s port. (Updatable)
ssl_key str Optional The PEM-formatted private key for the SSL certificate set in the ssl_cert field. (Updatable)
stickiness str Optional Controls how session stickiness is handled on this port. (Choices: none, table, http_cookie; Updatable)
nodes (sub-options) list Optional A list of nodes to apply to this config. These can alternatively be configured through the nodebalancer_node module. (Updatable)

nodes

Field Type Required Description
label str Required The label for this node.
address str Required The private IP Address where this backend can be reached. This must be a private IP address. (Updatable)
weight int Optional Nodes with a higher weight will receive more traffic. (Updatable)
mode str Optional The mode this NodeBalancer should use when sending traffic to this backend. (Choices: accept, reject, drain, backup; Updatable)
