# 安装并使用docker #

### 1.安装 ###

yum -y install docker

![安装][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjE0NDM3OQ_size_16_color_FFFFFF_t_70]

![完成安装][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjE0NDM3OQ_size_16_color_FFFFFF_t_70 1]

### 2.查看版本信息 ###

docker version

![查看版本信息][20200304112048255.png]

### 3.启动docker ###

service docker start

![启动docker][docker]

### 4.创建并编辑docker文件 ###

touch Dockerfile
    vim Dockerfile

内容如下:

# FROM ：表示用哪个基础镜像去构建新的镜像，这里java:8, 也就是jdk1.8。
    FROM java:8
    
    # 作者信息
    MAINTAINER  Jacktu
    
    # 用于指定持久化目录
    VOLUME /opt/projects/docker/volume
    
    # 使用copy将宿主机中的jar包，拷贝至容器中的对应位置
    COPY jacktu.jar /jacktu.jar
    
    # 执行Linux命令(/jacktu.jar是容器中的jar包)
    CMD java -jar /jacktu.jar --port=8899 --spring.profiles.active=dat
    
    # 对外暴露的端口
    EXPOSE 8899
    
    # docker run -d -p 8899:8899 --name jacktu_container jacktu_mirror
    # -d 后台运行,-p 本地:镜像端口 --name 容器名 镜像名

![编写Dockerfile][Dockerfile]

### 5.拉取java:8镜像 ###

docker pull java:8

![拉取java:8][java_8]

### 6.创建镜像 ###

docker build -t 镜像名 .

![拉取java:8][java_8 1]

### 7.查看镜像 ###

docker images

![查看镜像][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjE0NDM3OQ_size_16_color_FFFFFF_t_70 2]

### 8.创建容器并运行,jar包启动页面可以访问 ###

docker run -d -p 内部端口:外部端口 --name 容器名  镜像名

![创建容器并运行][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjE0NDM3OQ_size_16_color_FFFFFF_t_70 3]

![容器运行,页面也就启动了][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjE0NDM3OQ_size_16_color_FFFFFF_t_70 4]

### 9.查看容器 / 查看docker相关容器 / 查看容器id ###

docker ps / docker ps -a / docker ps -aq

![查看容器][20200304112258738.png]

### 10.停止容器 ###

docker stop 容器id

![停止容器][20200304112258738.png]

### 11.删除容器 ###

docker rm 容器id

![删除容器][20200304112335770.png]

### 12.删除镜像 ###

docker rmi 镜像名
