Using PVM environment on CVM, but template creation keeps failing consistently.

[zhang3feng]

Question

按照文档执行
cubemastercli tpl create-from-image \ --image cube-sandbox-cn.tencentcloudcr.com/cube-sandbox/sandbox-code:latest \ --writable-layer-size 1G \ --expose-port 49999 \ --expose-port 49983 \ --probe 49999

然后监控创建状态。报错如下：
2026/05/14 21:06:35 [1/7] PULLING progress=100% template_id=tpl-10822ef72e4142b6841a8da4 job_id=2ccb09ad-e615-4a04-93d5-aac2abd18779 error=docker pull cube-sandbox-int.tencentcloudcr.com/cube-sandbox/sandbox-code:latest failed: exit status 1: latest: Pulling from cube-sandbox/sandbox-code

也尝试用docker pull 这个镜像 也是同样不行。不过在本地环境可以docker pull下这个镜像

Hi @zhang3feng, thanks for reporting this issue.

A few things we noticed:

1. The command you shared uses cube-sandbox-cn.tencentcloudcr.com, but the error log shows it's pulling from cube-sandbox-int.tencentcloudcr.com — these are different registries. Could you double-check which command you actually executed?

2. Since the error indicates a pull failure from cube-sandbox-int, if your machine is in mainland China, network access to the international registry may be restricted. Please make sure you're using the cube-sandbox-cn registry.

To help us further diagnose, could you provide the following about your deployment machine:

• Is this a CVM cloud server? What region?
• OS version (cat /etc/os-release)
• Docker version (docker version)
• Disk space (df -h)
• Memory (free -h)
• Network test — can the machine reach the registry? (curl -I https://cube-sandbox-int.tencentcloudcr.com)

Thanks!

我开始用的国内镜像不行，又用了国际的同样报错，截图的时候就可能没有统一。CVM是云服务器，在国内，北京区域。硬盘50G。Docker使用的沙箱里自带的。

Can you check the disk usage with df? I guess it might be due to insufficient disk space for downloading the image
