华为云之SWR容器镜像服务实战

一、SWR容器镜像服务介绍

华为云容器镜像服务（SoftWare Repository for Container）是一种支持容器镜像全生命周期管理的服务，提供简单易用、安全可靠的镜像管理功能，帮助用户快速部署容器化服务。

二、检查本地docker环境

1.检查docker版本

[root@node ~]# docker -v
Docker version 20.10.17, build 100c701

2.检查docker状态

[root@node ~]# systemctl status docker
● docker.service - Docker Application Container Engine
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2022-10-18 17:00:12 CST; 5h 16min ago
     Docs: https://docs.docker.com
 Main PID: 11773 (dockerd)
    Tasks: 131
   Memory: 849.9M

三、生成docker镜像压缩包

1.查看本地镜像列表

[root@node ~]# docker images |grep nginx
nginx                                                                1.21                   605c77e624dd   9 months ago    141MB
nginx                                                                latest                 605c77e624dd   9 months ago    141MB

2.制作nginx的镜像压缩包

docker save nginx:1.21 > nginx.tar

3.查看压缩包

[root@node ~]# ls -sh nginx.tar 
140M nginx.tar

四、登录华为云容器镜像服务

五、上传镜像到华为云SWR——页面上传

1.创建组织

2.页面上传容器镜像压缩包

3.查看上传容器镜像

4.其它容器客户端临时登录SWR

5.下载SWR镜像仓库中容器

[root@serer01 ~]# docker pull swr.cn-north-4.myhuaweicloud.com/jeven/nginx:1.21
1.21: Pulling from jeven/nginx
2edcec3590a4: Pull complete 
e379e8aedd4d: Pull complete 
b8d6e692a25e: Pull complete 
f1db227348d0: Pull complete

Status: Downloaded newer image for swr.cn-north-4.myhuaweicloud.com/jeven/nginx:1.21
swr.cn-north-4.myhuaweicloud.com/jeven/nginx:1.21

6.查看下载的容器镜像

[root@serer01 ~]# docker images
REPOSITORY                                     TAG       IMAGE ID       CREATED        SIZE
nginx                                          1.21      0e901e68141f   4 months ago   142MB
swr.cn-north-4.myhuaweicloud.com/jeven/nginx   1.21      605c77e624dd   9 months ago   141MB

六、上传镜像到华为云SWR——客户端上传

1.临时登录SWR

2.重命名镜像

[root@serer01 ~]# docker tag busybox:1.28 swr.cn-north-4.myhuaweicloud.com/jeven/busybox:1.28

3.上传镜像到SWR

[root@serer01 ~]# docker push swr.cn-north-4.myhuaweicloud.com/jeven/busybox:1.28
The push refers to repository [swr.cn-north-4.myhuaweicloud.com/jeven/busybox]
432b65032b94: Pushed 
1.28: digest: sha256:74f634b1bc1bd74535d5209589734efbd44a25f4e2dc96d78784576a3eb5b335 size: 527

4.在华为云SWR上查看上传镜像

七、查看SWR镜像详细信息

1.查看镜像版本信息

2.查看SWR资源负载情况

3.查看SWR镜像中心
