docker安裝、docker使用、docker UI

1，安裝docker

a，切換到yum目錄

[root@docker ~]# cd /etc/yum.repos.d/

b，yum repolist

[root@docker yum.repos.d]# yum repolist

網站鏈接：https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/

c，wget docker-ce：

[root@docker yum.repos.d]# wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
--2019-09-27 15:02:18--  https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo

2019-09-27 15:02:21 (11.5 MB/s) - 已保存 “docker-ce.repo” [2424/2424])

[root@docker yum.repos.d]# 

d，修改docker-ce：
[root@docker yum.repos.d]# vi docker-ce.repo

改爲鏈接爲清華鏡像庫的：https://mirrors.tuna.tsinghua.edu.cn/docker-ce

:%s@https://download.docker.com/@https://mirrors.tuna.tsinghua.edu.cn/docker-ce/@

e，查看是否有程序包：

"docker-ce.repo" 83L, 2880C written
[root@docker yum.repos.d]# yum repolist

[root@docker yum.repos.d]# 

f，安裝docker-ce

[root@docker docker]# yum install docker -y

g，添加阿里雲加速器

[root@docker yum.repos.d]# vi /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://lptjipx8.mirror.aliyuncs.com"]
}

h，啓動docker

[root@docker docker]# systemctl restart docker
[root@docker docker]# systemctl enable docker

2，使用docker

a，在網上拉取鏡像

[root@docker ~]# docker pull nginx
Using default tag: latest
Trying to pull repository docker.io/library/nginx ... 
latest: Pulling from docker.io/library/nginx
b8f262c62ec6: Pull complete 
e9218e8f93b1: Pull complete 
7acba7289aa3: Pull complete 
Digest: sha256:aeded0f2a861747f43a01cf1018cf9efe2bdd02afd57d2b11fcc7fcadc16ccd1
Status: Downloaded newer image for docker.io/nginx:latest

b，查看鏡像：

anaconda-ks.cfg
[root@docker ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/nginx     latest              f949e7d76d63        2 days ago          126 MB
[root@docker ~]#

c，運行容器

[root@docker ~]# docker run -itd --name box busybox:latest
8234140bce2670116000b089a008c34622f33bbd539c3c3107bee1c464bdd44b
[root@docker ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
8234140bce26        busybox:latest      "sh"                4 seconds ago    

d，與宿主機交互

[root@docker ~]# docker run -itd -P --name nginx nginx:latest
ef5b9dc34138ea2e3d495faead86700636a7743b3e2aef4ac63d33caa26efa44
[root@docker ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                   NAMES

bca1348b8edf        busybox:latest      "sh"                     39 seconds ago      Up 38 seconds                               box
[root@docker ~]#
