新 Mac 上的错误
在全新的 Macbook（M1 Apple 芯片）上构建 Docker 镜像时，我得到了这个：
$ docker build -f Dockerfile-local-dev .
[+] Building 1.4s (3/3) FINISHED

failed to solve with frontend dockerfile.v0: failed to create LLB definition: pull access denied,repository does not exist or may require authorization: server message: insufficient_scope: authorization failed
这显然与拉取策略等有关，但它应该只找到一个本地映像并使用它，而不是尝试将其从全局 Docker 注册表中拉出...
在 Ubuntu 和其他 Mac 上没有错误！
奇怪的是，这适用于我所有其他机器，运行相同的 docker build (20.10.7,build f0df350)！

$ docker --version

图像存在于本地缓存中
$ docker image ls

在 Linux 机器（实际上是 WSL2）上对相同的代码和 Dockerfile 执行完全相同的操作时，效果非常好。和我的 Intel iMac 一样，所以这可能是与 M1 芯片和 Docker 版本有关的一些错误吗？
Dockerfile-local-dev 文件：
$ cat Dockerfile-local-dev
# Most definitely not to be used in production!
FROM nicecorp-empty-db
MAINTAINER ACME <devs@ACME.com>
# Allow nicecorpadmin user to create and drop databases (used for test runs)
RUN /etc/init.d/postgresql start && \
psql --command "CREATE DATABASE nicecorpdb_test_template OWNER nicecorpadmin;" && \
psql --command "ALTER USER nicecorpadmin SUPERUSER;"
# Allow all users to connect to all databases (used for test runs to allow ad-hoc databases)
RUN echo "host all all samenet password" >> /etc/postgresql/12/main/pg_hba.conf
RUN echo "max_connections = 1000" >> /etc/postgresql/12/main/postgresql.conf
运行时找到图像
当我尝试运行它时，似乎发现本地图像很好：
$ docker run nimble-empty-db:latest
