dockerhub.azk8s.cn how to get the multiple path image

[wangshuai-007]

In the hub.docker.com I want to get the dotnet core sdk like this command :docker pull mcr.microsoft.com/dotnet/core/sdk:2.2 and with dockerhub.azk8s.cn mirror,how can I get the right image this commond is not work:

docker pull dockerhub.azk8s.cn/mcr.microsoft.com/dotnet/core/sdk
Using default tag: latest
Error response from daemon: manifest for dockerhub.azk8s.cn/mcr.microsoft.com/dotnet/core/sdk:latest not found

docker pull dockerhub.azk8s.cn/microsoft/dotnet/core/sdk
Using default tag: latest
Error response from daemon: manifest for dockerhub.azk8s.cn/microsoft/dotnet/core/sdk:latest not found

*.azk8s.cn only supports dockerhub, gcr.io, quay.io, does not support mcr.microsoft.com, you could pull that image directly on azure china. @w371987114

We have set up a new proxy mcr.azk8s.cn for mcr.microsoft.com

@andyzhangx I tried this proxy twice (today and 2 weeks ago) and could not see any docker pull speed improvement. Anything wrong?

I was trying to pull edgeagent of Azure IoT Ege as below.

xxx@u64ms:~$ sudo docker pull mcr.microsoft.com/azureiotedge-agent:1.0
xxx@u64ms:~$ sudo docker pull mcr.azk8s.cn/azureiotedge-agent:1.0
1.0: Pulling from azureiotedge-agent

[andyzhangx]

sudo docker pull mcr.azk8s.cn/azureiotedge-agent:1.0

@tecchina the second time docker pull would only costs 5s:

@andyzhangx my 2nd pull was from scratch (i.e. no previously saved image) as well. I can understand an incremental pull will save time since the download size is much smaller. I meant I hadn't seen any downloading speed improvement with the proxy.

@tedchina We did not commit download speed improvement with the proxy. And what's your expectation?

[tedchina]

@andyzhangx Actually I did expect a speed improvement since the image pulling experience is horrible. I am fine and won't argue if that is beyond your plan or intention.

@tedchina would do you mean "horrible"? could you paste your "time docker pull ..." result?

[tedchina]

In my 2 attempts in separate days, each of them took more than 5 hours to just pull the edgeAgent image.

[andyzhangx]

Not sure where have you tried, in my Azure VM, it's only 5s.

Thanks @andyzhangx ... I just had a trial and confirm your proxy is now fast enough. The original repo is still as slow as my last two attempts of your proxy, however now your proxy is significantly faster, no matter started from scratch or after a suspended pull from the original repo. If nothing happened at your end, I have no clue why. One more piece of information is that my last 2 horrible attempts both took place on Sunday afternoons/evenings. Does this give you any clue?

BTW, I am in Shanghai with China Telecom fiber.

[andyzhangx]

@tedchina We detected slow docker pull issue and am now increasing the capacity. By the end of this week, the operation should be done.

[tedchina]

Glad to see you found the root cause and have a plan. Thanks ...
