镜像推送到 Azure Container Registry (ACR) 后，docker 镜像摘要不同

Question

我的机器上有一张图片：

mark@L-R910LPKW:~$ docker image ls --digests | grep debug
MyACR.azurecr.io/argoproj/argocd  debug               sha256:1346c0c07913d4da45beef22165aea26a24aab1be34eb166183c3d31ac19e8b8  b2d78a6e9763  7 hours ago   398 MB
mark@L-R910LPKW:~$

ACR上不存在：

mark@L-R910LPKW:~$ az acr repository show -n MyACR --repository argoproj/argocd
2023-05-12 00:42:56.707823 Error: repository "argoproj/argocd" is not found. Correlation ID: d5884fbd-4804-4502-bc72-e90e1843361c.
mark@L-R910LPKW:~$

让我们推动它：

mark@L-R910LPKW:~$ docker push MyACR.azurecr.io/argoproj/argocd:debug

mark@L-R910LPKW:~$

并检查推送图像的摘要：

mark@L-R910LPKW:~$ az acr repository show -n MyACR -t argoproj/argocd:debug --query digest -o tsv
sha256:a54903c9c8e867b458bb6f7cb41e3b26e7abf8346b7adc7ab87ebab066b2a95b
mark@L-R910LPKW:~$

请注意，

docker image ls --digests

命令将摘要报告为

sha256:1346c0c07913d4da45beef22165aea26a24aab1be34eb166183c3d31ac19e8b8

，这与我从 ACR 中得到的不同。

我错过了什么？

附言

我居然用podman伪装成docker：

mark@L-R910LPKW:~$ cat `which docker`
#!/bin/sh
[ -f /etc/containers/nodocker ] || \
echo "Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg." >&2
exec /usr/bin/podman "$@"
mark@L-R910LPKW:~$

希望这里没关系
