Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
changes list / elements=string | always | List of changed service attributes if a service has been altered, [] otherwise. Sample: ['container_labels', 'replicas'] |
rebuilt boolean | always | True if the service has been recreated (removed and created) Sample: True |
swarm_service dictionary | always | Dictionary of variables representing the current state of the service. Matches the module parameters format. Note that facts are not part of registered vars but accessible directly. Note that before Ansible 2.7.9, the return variable was documented as ansible_swarm_service , while the module actually returned a variable called ansible_docker_service . The variable was renamed to swarm_service in both code and documentation for Ansible 2.7.9 and Ansible 2.8.0. In Ansible 2.7.x, the old name ansible_docker_service can still be used.Sample: { "args": [ "3600" ], "command": [ "sleep" ], "configs": null, "constraints": [ "node.role == manager", "engine.labels.operatingsystem == ubuntu 14.04" ], "container_labels": null, "dns": null, "dns_options": null, "dns_search": null, "endpoint_mode": null, "env": [ "ENVVAR1=envvar1", "ENVVAR2=envvar2" ], "force_update": null, "groups": null, "healthcheck": { "interval": 90000000000, "retries": 3, "start_period": 30000000000, "test": [ "CMD", "curl", "--fail", "http://nginx.host.com" ], "timeout": 10000000000 }, "healthcheck_disabled": false, "hostname": null, "hosts": null, "image": "alpine:latest@sha256:b3dbf31b77fd99d9c08f780ce6f5282aba076d70a513a8be859d8d3a4d0c92b8", "labels": { "com.example.department": "Finance", "com.example.description": "Accounting webapp" }, "limit_cpu": 0.5, "limit_memory": 52428800, "log_driver": "fluentd", "log_driver_options": { "fluentd-address": "127.0.0.1:24224", "fluentd-async-connect": "true", "tag": "myservice" }, "mode": "replicated", "mounts": [ { "readonly": false, "source": "/tmp/", "target": "/remote_tmp/", "type": "bind", "labels": null, "propagation": null, "no_copy": null, "driver_config": null, "tmpfs_size": null, "tmpfs_mode": null } ], "networks": null, "placement_preferences": [ { "spread": "node.labels.mylabel" } ], "publish": null, "read_only": null, "replicas": 1, "replicas_max_per_node": 1, "reserve_cpu": 0.25, "reserve_memory": 20971520, "restart_policy": "on-failure", "restart_policy_attempts": 3, "restart_policy_delay": 5000000000, "restart_policy_window": 120000000000, "secrets": null, "stop_grace_period": null, "stop_signal": null, "tty": null, "update_delay": 10000000000, "update_failure_action": null, "update_max_failure_ratio": null, "update_monitor": null, "update_order": "stop-first", "update_parallelism": 2, "user": null, "working_dir": null } |
