+[이전 장(링크)](https://imprint.tistory.com/254) 에서는 `도커란 무엇인가`와 `도커 설치 방법`에 대해서 알아보았다. 
+이번 장에서는 `도커 이미지`를 실행하는 방법과 저장소에 `Push`, `Pull`하는 방법에 대해서 알아본다.
+모든 소스 코드는 [깃 허브 (링크)](https://github.com/roy-zz/spring-cloud) 에 올려두었다.
+
+---
+
+### Docker 실행
+
+우리의 마이크로서비스가 사용하고 있는 `MariaDB`를 도커 이미지로 실행하는 방법에 대해서 알아본다.
+
+1. 이미지 확인
+
+`hub.docker.com`에 접속하여 우리가 사용하려는 이미지 파일을 확인한다.
+
+![](docker_run_image/mariadb-in-dockerhub.png)
+
+2. 이미지 다운로드(생략 가능)
+
+아래의 커맨드를 입력하여 도커 이미지를 다운로드 한다.
+컨테이너를 실행할 때 PC가 없다면 자동으로 다운로드 하지만 이번에는 단계를 나누어 진행한다.
+
+```bash
+$ docker pull mariadb
+```
+
+![](docker_run_image/installed-mariadb-image.png)
+
+아래의 커맨드를 입력하여 도커 이미지 목록을 확인한다.
+
+```bash
+$ docker images
+```
+
+![](docker_run_image/docker-images.png)
+
+3. 컨테이너 실행
+
+아래의 커맨드를 입력하여 도커 컨테이너를 실행한다.
+
+```bash
+$ docker run -d -p 3306:3306 -e MYSQL_ALLOW_EMPTY_PASSWORD=true --name mariadb mariadb
+```
+
+![](docker_run_image/mariadb-container-run.png)
+
+아래의 커맨드를 입력하여 컨테이너 목록을 확인한다.
+
+```bash
+$ docker ps
+```
+
+![](docker_run_image/mariadb-docker-ps-result.png)
+
+도커를 실행할 때 사용하는 옵션에 대한 정보는 공식 홈페이지나 아래의 이미지를 참고한다.
+
+![](docker_run_image/docker-run-options.png)
+
+4. 컨테이너 접속 (단순 접속 확인, 실행 과정과 무관)
+
+아래의 커맨드를 입력하여 도커 컨테이너에 접속하여 정상적으로 실행되었는지 DB 클라이언트를 통해 접속해본다.
+
+```bash
+$ docker exec -it mariadb bash
+```
+
+![](docker_run_image/into-mariadb-container.png)
+
+5. 도커 로그 확인 (단순 로그 확인, 실행 과정과 무관)
+
+아래의 커맨드를 실행하여 도커의 로그를 확인해본다.
+
+```bash
+$ docker logs -f mariadb
+```
+
+![](docker_run_image/mariadb-logs.png)
+
+---
+
+### 이미지 생성 및 저장소 사용
+
+우리의 마이크로서비스중 유저 서비스를 도커 이미지로 만들고 저장소(Docker Hub)에 `Push`하는 방법에 대해서 알아본다.
+
+1. Dockerfile 생성
+
+`target` 디렉토리가 있는 경로에 아래와 같이 `Dockerfile`을 생성한다.
+
+```dockerfile
+FROM openjdk:17-ea-11-jdk-slim
+VOLUME /tmp
+COPY target/user-service-1.0.jar UserService.jar
+ENTRYPOINT ["java", "-jar", "UserService.jar"]
+```
+
+2. jar build
+

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.
