Сервисы в Kubernetes:

• Elasticsearch — elasticsearch
• MongoDB — mongodb-main

Namespace: staging

URL для входа в Web UI: graylog.domain.com

Генерация "PASSWORD_SECRET" и хеш пароля "ROOT_PASSWORD_SHA2"

PASSWORD_SECRET:

pwgen -s 80 1

Если пакет "pwgen" отсутствует в системе, то его необходимо установить.

ROOT_PASSWORD_SHA2:

echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1

Вводим пароль и получаем его хеш:

Enter Password: qwerty
