docker入门之简单的容器使用

首发:arppinging

一、运行容器

1)搜索和下载镜像

在之前我们打过一个比分,容器就像vmware workstation一样,而镜像类似于一个OVA文件,如果我们想让容器变得有意义,那镜像是我们必不可少的一个"货物"。

跟OVA文件类似,如果我们基于某一个镜像创建容器,那么在容器里面的任何操作不会被写入原本的镜像,除非对所有的操作进行一次镜像重构,把所有操作的结果导出形成一个新的镜像。

1.1 搜索需要的镜像

格式:docker search xxx
docker search:查找镜像。使用命令查找的镜像比较少,如有需要,可以进入dockerhub.com查找。

[root@node1 /]# docker search nginx

[root@node1 /]# 

以上就是查找nginx镜像的结果,以下是个字段的介绍:
NAME:镜像名。xxx/nignx -- xxx用户的nginx镜像,没有用户名的一般都是官方镜像。
DESCRIPTION:描述
STARS:用户评价
OFFICIAL:是否为官方镜像
AUTOATED:自动构建的

1.2 下载镜像

格式:docker image pull xxx:tag

有些镜像经过多次的修改,有很多的版本tag。在不指定版本的情况下,会自动下载最新的版本。

    [root@node1 yum.repos.d]# docker image pull nginx:1.14-alpine
    1.14-alpine: Pulling from library/nginx
    4fe2ade4980c: Pull complete 
    c691664ebb08: Pull complete 
    a6f6a50701b6: Pull complete 
    5980ba3b5a39: Pull complete 
    Digest: sha256:75cf17cdf89cbd8da65c83050ebdab1026b98cf217442d6a1f2a8892f47967d7
    Status: Downloaded newer image for nginx:1.14-alpine
    [root@node1 yum.repos.d]#

不指定版本下载

[root@node1 yum.repos.d]# docker pull busybox
    Using default tag: latest
    latest: Pulling from library/busybox
    90e01955edcd: Pull complete 
    Digest: sha256:2a03a6059f21e150ae84b0973863609494aad70f0a80eaeb64bddd8d92465812
    Status: Downloaded newer image for busybox:latest
    [root@node1 yum.repos.d]# 

1.3 查看已有的镜像

格式:docker image ls

[root@node1 /]# docker image ls
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               1.14-alpine         77bae8d00654        4 weeks ago         17.7MB
redis               4-alpine            05097a3a0549        2 months ago        30MB
busybox             latest              59788edf1f3e        2 months ago        1.15MB
[root@node1 /]# 

2)创建和运行容器

2.1 创建容器

格式:docker container create [opiton] image [command][arg...]

基于nginx:1.14-alpine镜像创建一个名为nginx_web1的容器。

[root@node1 /]# docker container create --name web_nginx nginx:1.14-alpine
a1146d1371979a4f4bccb5ada33d072b983b13cef7cb7d86af97dd149aa3fc6b

更多选项和命令可查docker使用手册。

2.2 查看容器

格式:docker container list -a

[root@node1 /]# docker container list -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                        PORTS               NAMES
a1146d137197        nginx:1.14-alpine   "nginx -g ‘daemon of…"   15 seconds ago      Created                                           web_nginx

2.3 运行容器

格式:docker container start [OPTIONS] CONTAINER [CONTAINER...]

启动web_nginx容器

[root@node1 /]# docker container start web_nginx
web_nginx
[root@node1 /]# 

2.4 进入容器

格式:docker exec [option] container [command] [arg...]
常用opiton:
-t:附加终端
-i:交互式访问

进入容器交互式sh界面

[root@node1 /]# docker exec -it web_nginx /bin/sh
/ # ls
bin    dev    etc    home   lib    media  mnt    proc   root   run    sbin   srv    sys    tmp    usr    var
/ # 
/ # ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
24: eth0@if25: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:11:00:02 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.2/16 brd 172.17.255.255 scope global eth0
       valid_lft forever preferred_lft forever
/ # ps aux
PID   USER     TIME  COMMAND
    1 root      0:00 nginx: master process nginx -g daemon off;
    6 nginx     0:00 nginx: worker process
   12 root      0:00 /bin/sh
   18 root      0:00 ps aux
/ # 

在docker服务器上访问docker上的nginx网页

[root@node1 /]# curl 172.17.0.2
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

<p>For online documentation and support please refer to
<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
[root@node1 /]# 

2.5 查看容器的状态

格式:docker ps [option]

常用option:
-a:所有的

查看正在运行的容器

[root@node1 /]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
a1146d137197        nginx:1.14-alpine   "nginx -g ‘daemon of…"   17 minutes ago      Up 8 minutes        80/tcp              web_nginx
[root@node1 /]# 

3)更加简便的方式

以上是标准的创建容器、启动容器、进入容器的步骤。但是步骤比较繁琐,在docker中,还有一种更加便捷的使用容器的方式,那就是docker run

docker run不仅能一次性创建、启动、进入容器,而且当镜像不存在的时候,还会自动下载镜像,然后再基于镜像创建容器。

格式:docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
常用option:
--name:容器名字
-i:交互式访问
-t:附加终端
-d:后台运行

3.1 创建和启动容器

使用docker run命令创建和启动一个名为web1_nginx的容器

[root@node1 /]# docker run --name  web1_nginx -d nginx:1.14-alpine
e4e2b8be9d575abeae83274b74f458ccee3379b0ee8c793ae50f6aa69f836e80
[root@node1 /]# 

3.2 查看容器的详细信息

格式:docker inspect containername

[root@node1 /]# docker inspect web1_nginx

<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>

[root@node1 /]# 

二、停止、恢复、关闭和删除容器

1)停止和恢复容器

停止容器类似于虚拟机的挂起。

停止格式:docker container pause [OPTIONS] CONTAINER [CONTAINER...]
恢复格式:docker container unpause [OPTIONS] CONTAINER [CONTAINER...]

1.1 查看容器状态

格式:docker container ps [option]

[root@node1 /]# docker container ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
e4e2b8be9d57        nginx:1.14-alpine   "nginx -g ‘daemon of…"   11 minutes ago      Up 11 minutes       80/tcp              web1_nginx
[root@node1 /]# 

1.2 停止容器

格式:docker container pause [OPTIONS] CONTAINER [CONTAINER...]

停止web1_nginx容器

[root@node1 /]# docker container pause web1_nginx
web1_nginx
[root@node1 /]# 

查看容器状态,可看到status上标注着paused

[root@node1 /]# docker container ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                   PORTS               NAMES
e4e2b8be9d57        nginx:1.14-alpine   "nginx -g ‘daemon of…"   15 minutes ago      Up 15 minutes (Paused)   80/tcp              web1_nginx
[root@node1 /]# 

测试容器是否在运行,会发现无法获取网页信息。(ps.但ping得通...不知道咋回事,知道的兄弟的可否告知一下。)

[root@node1 /]# curl 172.17.0.2

1.3 恢复容器

格式:docker container unpause [OPTIONS] CONTAINER [CONTAINER...]
恢复web1_nginx容器

[root@node1 /]# docker container unpause web1_nginx
web1_nginx
[root@node1 /]# 

查看容器状态

[root@node1 /]# docker container ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
e4e2b8be9d57        nginx:1.14-alpine   "nginx -g ‘daemon of…"   21 minutes ago      Up 21 minutes       80/tcp              web1_nginx
[root@node1 /]# 

获取容器中的网页信息

[root@node1 /]# curl 172.17.0.2
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

<p>For online documentation and support please refer to
<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
[root@node1 /]# 

2)关闭容器

关闭容器的方式有两种,一种是正常关闭,一种是关闭

2.1 关闭容器

格式:docker container stop [OPTIONS] CONTAINER [CONTAINER...]
关闭web1_nginx容器

[root@node1 /]# docker container stop web1_nginx
web1_nginx

2.2 查看容器状态

查看容器状态,此时ps查看不到已经关闭的容器信息,需要使用-a参数

[root@node1 /]# docker container ps 
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@node1 /]# docker container ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                     PORTS               NAMES
e4e2b8be9d57        nginx:1.14-alpine   "nginx -g ‘daemon of…"   27 minutes ago      Exited (0) 9 seconds ago                       web1_nginx
[root@node1 /]# 

可以看到status为exited

验证容器是否关闭,发现无法ping通

[root@node1 /]# ping 172.17.0.2
PING 172.17.0.2 (172.17.0.2) 56(84) bytes of data.
From 172.17.0.1 icmp_seq=10 Destination Host Unreachable
From 172.17.0.1 icmp_seq=11 Destination Host Unreachable
From 172.17.0.1 icmp_seq=12 Destination Host Unreachable

2.3 启动容器

启动已经关闭的web1_nginx容器

[root@node1 /]# docker container start web1_nginx
web1_nginx
[root@node1 /]# 

验证容器是否开启

[root@node1 /]# ping 172.17.0.2
PING 172.17.0.2 (172.17.0.2) 56(84) bytes of data.
64 bytes from 172.17.0.2: icmp_seq=1 ttl=64 time=0.076 ms
64 bytes from 172.17.0.2: icmp_seq=2 ttl=64 time=0.062 ms
64 bytes from 172.17.0.2: icmp_seq=3 ttl=64 time=0.062 ms
^C

rtt min/avg/max/mdev = 0.062/0.066/0.076/0.011 ms
[root@node1 /]# 

2.4 强制关闭容器

格式:docker container kill [OPTIONS] CONTAINER [CONTAINER...]

强制关闭web1_nginx容器

[root@node1 /]# docker container kill web1_nginx
web1_nginx
[root@node1 /]# 

查看和验证容器是否被关闭

[root@node1 /]# docker container ps -a 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                        PORTS               NAMES
e4e2b8be9d57        nginx:1.14-alpine   "nginx -g ‘daemon of…"   39 minutes ago      Exited (137) 56 seconds ago                       web1_nginx
[root@node1 /]# ping 172.16.0.2
PING 172.16.0.2 (172.16.0.2) 56(84) bytes of data.
^C
--- 172.16.0.2 ping statistics ---
65 packets transmitted, 0 received, 100% packet loss, time 63999ms

[root@node1 /]# 

3)删除容器

3.1 删除容器

将容器删除,容器处于关闭状态时才能被删除
格式:docker container rm [OPTIONS] CONTAINER [CONTAINER...]

[root@node1 /]# docker container rm web1_nginx
web1_nginx
[root@node1 /]# 

查看容器列表,发现容器web1_nginx容器已消失

[root@node1 /]# docker container ls -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@node1 /]# docker container ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@node1 /]#
