2021年2月22日。(February 22, 2021)

When command sudo docker ps -a show status EXITED, we can start it using

```
sudo docker start [CONTAINER NAME]
```

Try webserver in docker.

Create Dockerfile with contains:

                From nginx

Then just run command

                sudo docker build -t sinnud_www .

to create my own image sinnud_www.


                user@user-VirtualBox:~/docker/nginx$ cat run_nginx.sh 
#!/bin/bash

export VOLUME='/home/user/sinnud.github.io'

docker run  -d \
    --name sinnud_www \
    --publish 1246:80 \
    --volume ${VOLUME}:/usr/share/nginx/html \
    nginx

Then we can use web brouwser with URL: http://192.168.1.213:1246/

When container can't be stop because of permission issue, we can restart docker service:

```
sudo systemctl restart docker.service 
```
