+  --service-account-id=$(yc iam service-account get sa-default | grep ^id | awk '{print $2}') \
+  --role=editor
+```
+
+В папке подготовил **docker/ansbile** ansible playbook для установки docker-machine `ansible-playbook playbooks/docker-machine_install.yml` и установку go *Yandex.Cloud Docker machine driver*
+
+```bash
+docker-machine -D create \
+--driver yandex \
+--yandex-image-family "ubuntu-2004-lts" \
+--yandex-platform-id "standard-v1" \
+--yandex-folder-id $YC_FOLDER_ID \
+--yandex-sa-key-file $SA_KEY_PATH \
+--yandex-memory "4" \
+--yandex-nat=true \
+logging
+
+eval $(docker-machine env logging)
+docker-machine ip logging
+```
+
+Установка завершается ошибкой, разбираться нет смысла, так как docker-machine не является актуальным и более не поддерживается [Deprecate Docker Machine](https://github.com/docker/roadmap/issues/245).
+
+> Результат:
+
+```output

+```
+
+Дальнейшее разворачивание было выполнено через `terraform` и `ansible`. Файлы установки располагаются в папке `logging/infra/terraform` и `logging/infra/ansible`. Terraform `terraform -chdir=logging/infra/terraform/stage apply` создает машины с именами *docker-host-X* и *docker-logging-X*, запускает `logging/infra/ansible/playbooks/docker_logging.yml`, где выполняется установка docker-compose и запуск контейнеров. Причём адрес fluent сервера указывается изначально при установке из динамического `inventory.json` файла.

+### Логирование Docker-контейнеров

+
+Принято решение отказаться от fluentd и использовать [fluent-bit](https://docs.fluentbit.io/manual/pipeline/outputs/elasticsearch)
+Подсмотрев установку в keubernetes, использовал эти же версии [Kubernetes Observability: логгинг с EFK](https://habr.com/ru/companies/otus/articles/721004/) из блога **Блог компании OTUS, Kubernetes**

+Role Name
+=========
+
+A brief description of the role goes here.
+
+Requirements
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+
+Dependencies
+------------
+
+A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+    - hosts: servers
+      roles:
+         - { role: username.rolename, x: 42 }
+
+License
+-------
+
+BSD
+
+Author Information
+------------------
+
+An optional section for the role authors to include contact information, or a website (HTML is not allowed).

+Role Name
+=========
+
+A brief description of the role goes here.
+
+Requirements
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+
+Dependencies
+------------
+
+A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+    - hosts: servers
+      roles:
+         - { role: username.rolename, x: 42 }
+
+License
+-------
+
+BSD
+
+Author Information
+------------------
+
+An optional section for the role authors to include contact information, or a website (HTML is not allowed).
