sudo つけてみた、、、

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

web server

~ $ docker run -d -p 80:80 --name webserver nginx
docker: Cannot connect to the Docker daemon at tcp://192.168.59.103:2376. Is the docker daemon running?. See 'docker run --help'.

sudoつけてみた、、、

~ $ sudo docker run -d -p 80:80 --name webserver nginx
Password:

ブラウザで localhost みると、、、

オーケー！

プロセスみてみる、、、sudoつけてね

~ $ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9e4134e2e67d nginx "nginx -g 'daemon ..." 17 minutes ago Up 16 minutes 0.0.0.0:80->80/tcp, 443/tcp webserver

nginxが動いているね。

webserver を止めてみる、、、

~ $ sudo docker stop webserver
webserver
~ $ sudo docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6ed0928c3844 hello-world "/hello" 7 minutes ago Exited (0) 7 minutes ago kind_bhabha
9e4134e2e67d nginx "nginx -g 'daemon ..." 19 minutes ago Exited (0) 9 seconds ago webserver

nginxがExitedしているね。

webserverのコンテナを削除してみる、、、

~ $ sudo docker rm -f webserver
webserver
~ $ sudo docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6ed0928c3844 hello-world "/hello" 8 minutes ago Exited (0) 8 minutes ago kind_bhabha

削除されているね。
