Docker容器进阶

一、Docker私有仓库

1、仓库镜像

Docker hub官方已提供容器镜像registry,用于搭建私有仓库

拉取镜像

[root@docker ~]# docker pull  daocloud.io/library/registry:latest

2、运行容器

[root@docker ~]# docker run --name "pri_registry" --restart=always -d -p 5000:5000 daocloud.io/library/registry
abdd5dd0c05b372dbd06899319e6747f4af2f6a332fc6e09049fe84951365e02

3、查看容器

[root@docker ~]# docker ps
CONTAINER ID   IMAGE                          COMMAND                  CREATED          STATUS         PORTS                                       NAMES
abdd5dd0c05b   daocloud.io/library/registry   "/entrypoint.sh /etc…"   20 minutes ago   Up 8 minutes   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp   pri_registry

4、连接容器查看端口状态

[root@docker ~]# docker exec -it abdd /bin/sh
/ # netstat -auntpl | grep 5000
tcp        0      0 :::5000                 :::*                    LISTEN      1/registry
/ # netstat -lnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 :::5000                 :::*                    LISTEN      1/registry
Active UNIX domain sockets (only servers)
Proto RefCnt Flags       Type       State         I-Node PID/Program name    Path

[root@docker ~]# curl -I 127.0.0.1:5000

5、仓库功能测试

[root@docker ~]# docker pull busybox
Using default tag: latest
latest: Pulling from library/busybox
Digest: sha256:ef320ff10026a50cf5f0213d35537ce0041ac1d96e9b7800bafd8bc9eff6c693
Status: Image is up to date for busybox:latest
docker.io/library/busybox:latest
#给镜像打tag
[root@docker ~]# docker tag busybox  192.168.10.11:5000/busybox:v1

[root@docker ~]# vim /etc/docker/daemon.json
{ "insecure-registries":["192.168.10.11:5000"]}

[root@docker ~]# systemctl restart docker

#上传镜像到私有仓库
[root@docker ~]# docker push  192.168.10.11:5000/busybox:v1       

[root@docker ~]# docker rmi  192.168.10.11:5000/busybox:v1

#从私有仓库下载镜像
[root@docker ~]# docker pull 192.168.10.11:5000/busybox:v1

[root@docker ~]# docker images
REPOSITORY                     TAG       IMAGE ID       CREATED         SIZE
192.168.10.11:5000/busybox     v1        7a80323521cc   7 days ago      1.24MB

二、部署Docker-WebUI

1、下载并运行容器

[root@docker ~]# docker pull uifd/ui-for-docker 
[root@docker ~]# docker images
uifd/ui-for-docker      latest    965940f98fa5   5 years ago     8.1MB
[root@docker ~]# docker run -it -d --name docker-web -p 9000:9000 -v  /var/run/docker.sock:/var/run/docker.sock docker.io/uifd/ui-for-docker

2、浏览器访问测试
