Hashicop Vault будем ставить в docker-compose

ставим docker:

yum remove docker docker-engine docker.io
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager —add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce -y
systemctl start docker
systemctl enable docker

ставим docker-compose

https://github.com/docker/compose/releases
на текущий момент самая последняя версия:
2,6,1

https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-linux-x86_64

выкачиваем её:

curl -L «https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-linux-x86_64» -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

всё готово.

теперь приступим к установке  Vault

cat docker-compose.yml

version: '3.8'

services:

cat vault/policies/app-policy.json

{
  "path": {
    "kv/data/app/*": {
      "policy": "read"
    }
  }
}

запускаем:

docker-compose up -d

ждём пока соберётся.
потом заходим в Vault:

http://192.168.1.170:8200

ставим
Key shares = 5
Key threshold = 3
но вы можете установить любое другое значение

мы получаем 5 ключей.

внизу справа можно скачать json

{
  "keys": [
    "22b07e26d89c620dc68cab7a7e5046d8a807390fe55a477d091f9178bc8339af3c",

  ],
  "root_token": "s.Rw5WixMGCf84xZD1nHhndj3K"
}

далее нужно ввести ключи по очереди:

далее выбираем рутовый токен который мы скачали вместе с ключами:

мы так же можем выбрать и другие методы:

но мы остановимся на токене

всё ок.
попадаем в панель:

проверим Consul

http://192.168.1.170:8500/

==========================================

добавим аутентификацию по логину и паролю:

ну всё готово. пользователь есть теперь зададим политику.

идём на офф сайт
https://www.vaultproject.io/docs/concepts/policies
или смотрим в default возможные варианты настройки

вставляем политику:

path "secret/*" {
  capabilities = ["create", "read", "update", "patch", "delete", "list"]
}

всё можно создавать секрет
