docker desktop如何第一次创建镜像

小KKKKKKKK
根据业务需要,需要使用centos环境,但是安装的docker desktop没有任务镜像可用
登录docker hub去查询需要的镜像文件

image-20230425155758530.png image-20230425155839477.png点击Tags
image-20230425155908383.png先选择复制对应的拉去命令“docker pull centos:latest”
那么问题来了,我直接执行命令,拉取的到底是什么架构的镜像,这里可以尝试拉取一次
win + r --> cmd
docker pull centos:latest
返回
latest: Pulling from library/centos
a1d0c7532777: Pull complete
Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177
Status: Downloaded newer image for centos:latest
docker.io/library/centos:latest
看起来只会拉去第一个架构的镜像
如果我们需要拉取非第一个镜像那该怎么操作?
这里我们选择arm64/v8的镜像

image-20230425165347981.png拉取的命令就改成
docker pull centos:latest@sha256:65a4aad1156d8a0679537cb78519a17eb7142e05a968b26a5361153006224fdc
