Laboratory work X

Данная лабораторная работа посвещена изучению систем управления пакетами на примере Hunter

$ open https://github.com/ruslo/hunter

Tasks

  • 1. Создать публичный репозиторий с названием lab10 на сервисе GitHub
  • 2. Сгенирировать токен для доступа к сервису GitHub с правами repo
  • 3. Выполнить инструкцию учебного материала
  • 4. Ознакомиться со ссылками учебного материала
  • 5. Составить отчет и отправить ссылку личным сообщением в Slack

Tutorial

Устанавливаем переменные окружений GITHUB_USERNAME и GITHUB_TOKEN.

$ export GITHUB_USERNAME=TalkedDevotee # Переменная окружения GITHUB_USERNAME
$ export GITHUB_TOKEN=****************************** # Переменная окружения GITHUB_TOKEN

Скачиваем проект hub.

$ cd ${GITHUB_USERNAME}/workspace # Переходим в папку workspace
$ pushd . # Помещает имя текущего каталога в стек и осуществляет переход в каталог
$ source scripts/activate # Вставляем в файл скрипта
$ go get github.com/github/hub # Скачиваем проект hub
$ mkdir ~/.config # Создаем файл конфигуриции
$ cat > ~/.config/hub <<EOF
github.com:
- user: ${GITHUB_USERNAME}
  oauth_token: ${GITHUB_TOKEN}
  protocol: https
EOF
# - user - Имя пользователя
# - oath_token - аутентификация токена репозитория
# - protocol - протокол канала
$ git config --global hub.protocol https # Вносим в конфигурацию протокол от hub'a

Чтобы извлечь хеш-сумму из файла, для этого скачиваем архив из предыдущей работы №9.

$ wget https://github.com/${GITHUB_USERNAME}/lab09/archive/v0.1.0.0.tar.gz # Скачиваем архив
$ export PRINT_SHA1=`openssl sha1 v0.1.0.0.tar.gz | cut -d'=' -f2 | cut -c2-41`
$ echo $PRINT_SHA1 # Контроль хеша
f51e8b4d7dc92ff540b02db01397b134c9afed1e
$ rm -rf v0.1.0.0.tar.gz # Удаляем архив

Подключаем hub.

$ git clone https://github.com/ruslo/hunter projects/hunter # Скачиваем гит hub
$ cd projects/hunter && git checkout v0.19.137 # Переходим в папку hunter и на v0.19.137
$ git remote show # Список управления репозиториев
$ hub fork # Включаем репозиторий
$ git remote show # Список управления репозиториев обновился
TalkedDevotee
origin
$ git remote show ${GITHUB_USERNAME} # Информация гита

  Внешние ветки:
