Manages the Docker nodes via Swarm Manager.
This module allows to change the node's role, its availability, and to modify, add or remove node labels.
- name: Set node role docker_node: hostname: mynode role: manager
- name: Set node availability docker_node: hostname: mynode availability: drain
- name: Replace node labels with new labels docker_node: hostname: mynode labels: key: value labels_state: replace
- name: Merge node labels and new labels docker_node: hostname: mynode labels: key: value
- name: Remove all labels assigned to node docker_node: hostname: mynode labels_state: replace
- name: Remove selected labels from the node docker_node: hostname: mynode labels_to_remove: - key1 - key2
tls: default: false description: - Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if I(validate_certs) is set to C(yes) as well, it will take precedence. - If the value is not specified in the task, the value of environment variable C(DOCKER_TLS) will be used instead. If the environment variable is not set, the default value will be used. type: bool role: choices: - manager - worker description: Node role to assign. If not provided then node role remains unchanged. type: str debug: default: false description: - Debug mode type: bool labels: description: - User-defined key/value metadata that will be assigned as node attribute. - Label operations in this module apply to the docker swarm node specified by I(hostname). Use M(docker_swarm) module to add/modify/remove swarm cluster labels. - The actual state of labels assigned to the node when module completes its work depends on I(labels_state) and I(labels_to_remove) parameters values. See description below. type: dict ca_cert: aliases: - tls_ca_cert - cacert_path description: - Use a CA certificate when performing server verification by providing the path to a CA certificate file. - If the value is not specified in the task and the environment variable C(DOCKER_CERT_PATH) is set, the file C(ca.pem) from the directory specified in the environment variable C(DOCKER_CERT_PATH) will be used. type: path timeout: default: 60 description: - The maximum amount of time in seconds to wait on a response from the API. - If the value is not specified in the task, the value of environment variable C(DOCKER_TIMEOUT) will be used instead. If the environment variable is not set, the default value will be used. type: int hostname: description: - The hostname or ID of node as registered in Swarm. - If more than one node is registered using the same hostname the ID must be used, otherwise module will fail. required: true type: str client_key: aliases: - tls_client_key - key_path description: - Path to the client's TLS key file. - If the value is not specified in the task and the environment variable C(DOCKER_CERT_PATH) is set, the file C(key.pem) from the directory specified in the environment variable C(DOCKER_CERT_PATH) will be used. type: path api_version: aliases: - docker_api_version default: auto description: - The version of the Docker API running on the Docker Host. - Defaults to the latest version of the API supported by Docker SDK for Python and the docker daemon. - If the value is not specified in the task, the value of environment variable C(DOCKER_API_VERSION) will be used instead. If the environment variable is not set, the default value will be used. type: str client_cert: aliases: - tls_client_cert - cert_path description: - Path to the client's TLS certificate file. - If the value is not specified in the task and the environment variable C(DOCKER_CERT_PATH) is set, the file C(cert.pem) from the directory specified in the environment variable C(DOCKER_CERT_PATH) will be used. type: path docker_host: aliases: - docker_url default: unix://var/run/docker.sock description: - The URL or Unix socket path used to connect to the Docker API. To connect to a remote host, provide the TCP connection string. For example, C(tcp://192.0.2.23:2376). If TLS is used to encrypt the connection, the module will automatically replace C(tcp) in the connection URL with C(https). - If the value is not specified in the task, the value of environment variable C(DOCKER_HOST) will be used instead. If the environment variable is not set, the default value will be used. type: str ssl_version: description: - Provide a valid SSL version number. Default value determined by ssl.py module. - If the value is not specified in the task, the value of environment variable C(DOCKER_SSL_VERSION) will be used instead. type: str availability: choices: - active - pause - drain description: Node availability to assign. If not provided then node availability remains unchanged. type: str labels_state: choices: - merge - replace default: merge description: - It defines the operation on the labels assigned to node and labels specified in I(labels) option. - Set to C(merge) to combine labels provided in I(labels) with those already assigned to the node. If no labels are assigned then it will add listed labels. For labels that are already assigned to the node, it will update their values. The labels not specified in I(labels) will remain unchanged. If I(labels) is empty then no changes will be made. - Set to C(replace) to replace all assigned labels with provided ones. If I(labels) is empty then all labels assigned to the node will be removed. type: str tls_hostname: default: localhost description: - When verifying the authenticity of the Docker Host server, provide the expected name of the server. - If the value is not specified in the task, the value of environment variable C(DOCKER_TLS_HOSTNAME) will be used instead. If the environment variable is not set, the default value will be used. type: str validate_certs: aliases: - tls_verify default: false description: - Secure the connection to the API by using TLS and verifying the authenticity of the Docker host server. - If the value is not specified in the task, the value of environment variable C(DOCKER_TLS_VERIFY) will be used instead. If the environment variable is not set, the default value will be used. type: bool labels_to_remove: description: - List of labels that will be removed from the node configuration. The list has to contain only label names, not their values. - If the label provided on the list is not assigned to the node, the entry is ignored. - If the label is both on the I(labels_to_remove) and I(labels), then value provided in I(labels) remains assigned to the node. - If I(labels_state) is C(replace) and I(labels) is not provided or empty then all labels assigned to node are removed and I(labels_to_remove) is ignored. elements: str type: list
