# 1. 拉取镜像
docker pull kibana:7.4.2          # 可视化检索数据

# 2. 创建容器  虚拟机IP:这个IP需要是docker内部IP 
# 通过 下面指令查询
docker ps
docker inspect 容器id

#     "bridge": {
#         ...
#         "IPAddress": "`172.17.0.4`",

# 3. 设置开机启动
docker update kibana --restart=always

# 4. 测试
# 访问Kibana： http://虚拟机IP:5601/app/kibana

# 1. 拉取镜像
docker pull nginx:1.10

# 2. 创建容器
mkdir -p /home/slienceme/docker/nginx/html  # 创建多级文件夹
mkdir -p /home/slienceme/docker/nginx/logs
mkdir -p /home/slienceme/docker/nginx/conf

docker run -p 80:80 --name nginx \

docker run --name my-custom-nginx-container \
	-v /host/path/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx

# 3. 设置开机启动
docker update nginx --restart=always

# 另外也可以先不拉取镜像，直接run，docker发现没有会自动拉取
# 随便启动一个nginx实例，只是为了复制出配置
docker run -p80:80 --name nginx -d nginx:1.10   

# 创建映射文件夹
mkdir -p /home/slienceme/docker/nginx/html
mkdir -p /home/slienceme/docker/nginx/logs

# 将容器内的配置文件拷贝到/home/slienceme/docker/nginx/conf/ 下
docker container cp nginx:/etc/nginx/  /home/slienceme/docker/nginx/conf/ 

# 这里复杂成功了，但是移动可能会出现权限问题nginx是root
# 递归修改文件及子目录和文件权限
sudo chown -R slienceme:slienceme /home/slienceme/docker/nginx/conf/nginx

#由于拷贝完成后会在config中存在一个nginx文件夹，所以需要将它的内容移动到conf中
mv /home/slienceme/docker/nginx/conf/nginx/* /home/slienceme/docker/nginx/conf/
rm -rf /home/slienceme/docker/nginx/conf/nginx

# 终止原容器
docker stop nginx

# 执行命令删除原容器
docker rm nginx

# 创建新的Nginx，执行以下命令
docker run -p 80:80 --name nginx \
 -v /mydata/nginx/html:/usr/share/nginx/html \
 -v /mydata/nginx/logs:/var/log/nginx \
 -v /mydata/nginx/conf/:/etc/nginx \
 -d nginx:1.10
 
# 设置开机启动nginx
docker update nginx --restart=always

# 创建“/mydata/nginx/html/index.html”文件，测试是否能够正常访问
echo '<h2>hello nginx!</h2>' >index.html

# 访问：http://ngix所在主机的IP:80/index.html
