+# PostgreSQL Client Authentication Configuration File
+# ===================================================
+#
+# Refer to the "Client Authentication" section in the PostgreSQL
+# documentation for a complete description of this file.  A short
+# synopsis follows.
+#
+# This file controls: which hosts are allowed to connect, how clients
+# are authenticated, which PostgreSQL user names they can use, which
+# databases they can access.  Records take one of these forms:
+#
+# local      DATABASE  USER  METHOD  [OPTIONS]
+# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+#
+# (The uppercase items must be replaced by actual values.)
+#
+# The first field is the connection type: "local" is a Unix-domain
+# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
+# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
+# plain TCP/IP socket.
+#
+# DATABASE can be "all", "sameuser", "samerole", "replication", a
+# database name, or a comma-separated list thereof. The "all"
+# keyword does not match "replication". Access to replication
+# must be enabled in a separate record (see example below).
+#
+# USER can be "all", a user name, a group name prefixed with "+", or a
+# comma-separated list thereof.  In both the DATABASE and USER fields
+# you can also write a file name prefixed with "@" to include names
+# from a separate file.
+#
+# ADDRESS specifies the set of hosts the record matches.  It can be a
+# host name, or it is made up of an IP address and a CIDR mask that is
+# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
+# specifies the number of significant bits in the mask.  A host name
+# that starts with a dot (.) matches a suffix of the actual host name.
+# Alternatively, you can write an IP address and netmask in separate
+# columns to specify the set of hosts.  Instead of a CIDR-address, you
+# can write "samehost" to match any of the server's own IP addresses,
+# or "samenet" to match any address in any subnet that the server is
+# directly connected to.
+#
+# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
+# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
+# Note that "password" sends passwords in clear text; "md5" or
+# "scram-sha-256" are preferred since they send encrypted passwords.
+#
+# OPTIONS are a set of options for the authentication in the format
+# NAME=VALUE.  The available options depend on the different
+# authentication methods -- refer to the "Client Authentication"
+# section in the documentation for a list of which options are
+# available for which authentication methods.
+#
+# Database and user names containing spaces, commas, quotes and other
+# special characters must be quoted.  Quoting one of the keywords
+# "all", "sameuser", "samerole" or "replication" makes the name lose
+# its special character, and just match a database or username with
+# that name.
+#
+# This file is read on server startup and when the server receives a
+# SIGHUP signal.  If you edit the file on a running system, you have to
+# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
+# or execute "SELECT pg_reload_conf()".
+#
+# Put your actual configuration here
+# ----------------------------------
+#
+# If you want to allow non-local connections, you need to add more
+# "host" records.  In that case you will also need to make PostgreSQL
+# listen on a non-local interface via the listen_addresses
+# configuration parameter, or via the -i or -h command line switches.
+
+
+
+# TYPE  DATABASE        USER            ADDRESS                 METHOD
+
+# "local" is for Unix domain socket connections only
+local   all             all                                     trust
+# IPv4 local connections:
+host    all             all             127.0.0.1/32            md5
+# IPv6 local connections:
+host    all             all             ::1/128                 md5
+# Allow replication connections from localhost, by a user with the
+# replication privilege.
+local   replication     all                                     trust
+host    replication     all             127.0.0.1/32            md5

+Выполнение [домашнего задания](https://github.com/netology-code/mnt-homeworks/blob/MNT-13/09-ci-03-cicd/README.md)
+по теме "9.3. CI\CD".
+
+## Q/A
+
+### Задание 1
+
+> Подготовка к выполнению
+> 1. Создаём 2 VM в yandex cloud со следующими параметрами: 2CPU 4RAM Centos7(остальное по минимальным требованиям)
+> 2. Прописываем в [inventory](./infrastructure/inventory/hosts.yml) [playbook'a](./infrastructure/site.yml) созданные хосты
+> 3. Добавляем в [files](./infrastructure/files/) файл со своим публичным ключом (id_rsa.pub). Если ключ называется иначе - найдите таску в плейбуке, которая использует id_rsa.pub имя и исправьте на своё
+> 4. Запускаем playbook, ожидаем успешного завершения
+
+```shell
+ansible-playbook -i inventory/hosts.yml site.yml
+```
+
+
+```text
+<...>
+PLAY RECAP *****************************************************************************************************************

+```
+
+> 5. Проверяем готовность Sonarqube через [браузер](http://localhost:9000)
+> 6. Заходим под admin\admin, меняем пароль на свой
+
+![sonar_main](./img/sonar_main.png)
+
+> 7.  Проверяем готовность Nexus через [бразуер](http://localhost:8081)
+> 8. Подключаемся под admin\admin123, меняем пароль, сохраняем анонимный доступ
+
+![sonar_main](./img/nexus_main.png)
+
+### Задание 2
+
+> Знакомство с SonarQube
+
+> 1. Создаём новый проект, название произвольное
+> 2. Скачиваем пакет sonar-scanner, который нам предлагает скачать сам sonarqube
+
+Для скачивания пакета актуальной версии на текущий момент:
+
+```shell
+curl https://binaries.sonarsource.com/Distribution/sonar-scanner-cli/sonar-scanner-cli-4.7.0.2747-linux.zip -o sonar-scanner-cli-4.7.0.2747-linux.zip
+```
+
+Затем нужно распаковать архив в любую директорию:
+
+```shell
+unzip sonar-scanner-cli-4.7.0.2747-linux.zip -d ~/.local/share/
+```
+
+Внутри распакованной директории будет находиться директория `bin`, которую и нужно добавить в `$PATH`.
+
+> 3. Делаем так, чтобы binary был доступен через вызов в shell (или меняем переменную PATH или любой другой удобный вам способ)
+> 4. Проверяем `sonar-scanner --version`
+
+```shell
+sonar-scanner --version
+```
+
+```text
+INFO: Scanner configuration file: ~/.local/share/sonar-scanner/conf/sonar-scanner.properties
+INFO: Project root configuration file: NONE
+INFO: SonarScanner 4.7.0.2747
+INFO: Java 11.0.14.1 Eclipse Adoptium (64-bit)
+INFO: Linux 5.10.102.1-microsoft-standard-WSL2 amd64
+```
+
+> 5. Запускаем анализатор против кода из директории [example](./example) с дополнительным ключом `-Dsonar.coverage.exclusions=fail.py`
+
+```shell
+sonar-scanner \
+  -Dsonar.projectKey=sao \
+  -Dsonar.sources=. \
+  -Dsonar.host.url=http://<sonar-01>:9000 \
+  -Dsonar.login=<token> \
+  -Dsonar.coverage.exclusions=fail.py
+```
+
+```text
+<...>
+INFO: ------------------------------------------------------------------------
+INFO: EXECUTION SUCCESS
+INFO: ------------------------------------------------------------------------
+INFO: Total time: 34.848s
+INFO: Final Memory: 8M/37M
+INFO: ------------------------------------------------------------------------
+```
+
+> 6. Смотрим результат в интерфейсе
+
+![sonar_project_analysis](./img/sonar_project_analysis.png)
+
+> 7. Исправляем ошибки, которые он выявил(включая warnings)
+
+Исправляем функцию, чтобы она выглядела следующим образом:
+
+```python
+def increment(index):
+    newIndex = index+1
+    return newIndex
+```
+
+И убираем из функции `print_numb` конструкцию `pass`.
+
+> 8. Запускаем анализатор повторно - проверяем, что QG пройдены успешно
+> 9. Делаем скриншот успешного прохождения анализа, прикладываем к решению ДЗ
+
+![sonar_project_analysis_fix](./img/sonar_project_analysis_fix.png)
+
+### Задание 3
+
+> Знакомство с Nexus
+> 1. В репозиторий `maven-releases` загружаем артефакт с GAV параметрами:
+>     1. groupId: netology
+>     2. artifactId: java
+>     3. version: 8_282
+>     4. classifier: distrib
+>     5. type: tar.gz
+
+![nexus_maven_upload](./img/nexus_maven_upload.png)
+
+> 2. В него же загружаем такой же артефакт, но с version: 8_102
+> 3. Проверяем, что все файлы загрузились успешно
+
+![nexus_maven_upload_success](./img/nexus_maven_upload_success.png)
+
+> 4. В ответе присылаем файл `maven-metadata.xml` для этого артефекта
+
+```xml
+<metadata modelVersion="1.1.0">
+    <groupId>netology</groupId>
+    <artifactId>java</artifactId>
+    <versioning>
+        <latest>8_282</latest>
+        <release>8_282</release>
+        <versions>

+        </versions>
+        <lastUpdated>20220824033600</lastUpdated>
+    </versioning>
+</metadata>
+```
+
+### Задание 4
+
+> Знакомство с Maven
+> 
+> Подготовка к выполнению
+> 1. Скачиваем дистрибутив с [maven](https://maven.apache.org/download.cgi)
+> 2. Разархивируем, делаем так, чтобы binary был доступен через вызов в shell (или меняем переменную PATH или любой другой удобный вам способ)
+
+Делать нужно по аналогии с `sonar-scanner` из [Задания 2](#задание-2)
+
+> 3. Удаляем из `apache-maven-<version>/conf/settings.xml` упоминание о правиле, отвергающем http соединение( раздел `mirrors->id`: `my-repository-http-blocker`)
+> 4. Проверяем `mvn --version`
+
+```shell
+mvn --version
+```
+
+```text
+Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)

+OS name: "linux", version: "5.10.102.1-microsoft-standard-wsl2", arch: "amd64", family: "unix"
+```
+
+> 5. Забираем директорию [mvn](./mvn) с pom
+
+> Основная часть
+> 1. Меняем в `pom.xml` блок с зависимостями под наш артефакт из первого пункта задания для Nexus (java с версией 8_282)
+> 2. Запускаем команду `mvn package` в директории с `pom.xml`, ожидаем успешного окончания
+
+```shell
+mvn package
+```
+
+```text
+[INFO] Building jar: ./mvn/target/simple-app-1.0-SNAPSHOT.jar

+```
+
+> 3. Проверяем директорию `~/.m2/repository/`, находим наш артефакт
+
+```shell
+ls -la ~/.m2/repository/netology/java/8_282
+```
+
+```text
