adc apply

Сергей Тихомиров

Определение

Считывает один или несколько документов (каждый документ может содержать несколько конфигураций объектов, разделенных строкой ---), генерирует объекты Kubernetes для каждой предоставленной конфигурации и применяет их на стороне сервера. Имена созданных ресурсов составляются из конфигурационного параметра metadata.name и опционально передаваемого префикса. Данная команда является идемпотентной.

Сгенерированная конфигурация зависит от параметра kind:

  • Для кластера (ImpalaCluster, TrinoCluster, SparkApplication, SparkHistoryServer) генерируется CR соответствующего оператора и необходимые секреты. Для SparkHistoryServer дополнительно генерируется секрет <metadata.name>-spark-history-properties.

  • Для оператора (ImpalaOperator, TrinoOperator, SparkOperator, KerberosOperator) генерируются Namespace, ServiceAccount, RBAC, Deployment, секрет для загрузки образа (если предоставлен) и объекты CRD.

  • Для Helm-конфигураций (Celeborn, YuniKorn) напрямую генерируются объекты workload:

    • Celeborn — StatefulSets, Service, ConfigMap, RBAC;

    • YuniKorn — k8shim Deployment, ConfigMap, RBAC.

Использование

$ adc apply --file <file> [--file <file>...] \
                          [--kubeconfig <kubeconfig>] \
                          [--prefix <prefix>] \
                          [--dry-run] \
                          [--only-crds | --only-rbac]
Аргументы
Параметр Описание

-f, --file

Путь к конфигурационному YAML-файлу. Можно предоставить несколько файлов, повторив флаг

-k, --kubeconfig

Путь к файлу kubeconfig. Значение по умолчанию — $KUBECONFIG

-p, --prefix

Префикс, который будет использован перед metadata.name для сгенерированного имени ресурса

--dry-run

Выводит сгенерированный манифест объекта, не применяя его. По умолчанию вывод не содержит конфигурацию объектов CRD

--only-crds

Генерирует или применяет только конфигурацию объектов CustomResourceDefinition. Не совместим с --only-rbac

--only-rbac

Генерирует или применяет только конфигурацию объектов ServiceAccount, Role, RoleBinding, ClusterRole и ClusterRoleBinding. Не совместим с --only-crds
