http server ， docker hub

https://hub.docker.com/_/httpd/

1.Create a Dockerfile in your project

FROM httpd:2.4
COPY ./public-html/ /usr/local/apache2/htdocs/

2. 在同级目录创建文件夹 public-html 

3. 将你想要访问的文件添加到 public-html 中

4. 创建镜像

docker build -t my-apache2 .

注：创建名为my-apache2 的镜像 ， Dockerfile 位置在当前目录

5. 运行

docker run -dit -p 9090:80 --name my-running-app my-apache2

注：

--expose=[]	Expose a port or a range of ports inside the container. These are additional to those exposed by the `EXPOSE` instruction
-P	Publish all exposed ports to the host interfaces
-p=[]	Publish a container᾿s port or a range of ports to the host format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort Both hostPort and containerPort can be specified as a range of ports. When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range, for example: -p 1234-1236:1234-1236/tcp When specifying a range for hostPort only, the containerPort must not be a range. In this case the container port is published somewhere within the specified hostPort range. (e.g., `-p 1234-1236:1234/tcp`) (use 'docker port' to see the actual mapping)
--link=""	Add link to another container (<name or id>:alias or <name or id>)

即： 访问主机的9090 端口时，映射到 80 端口（这个端口是容器 expose 的端口）

 

注：--name 是指定容器的名称

docker ps --format "table{{.ID}}\t{{.Names}}" -f name=my
CONTAINER ID        NAMES
65ca46ea5596        my-running-app
