Azure-devops-docs: How to express ACR image?

[AArnott]

The doc shows an ACR image being downloaded with:

resources:
  - container: my_private_container
    image: private:ubuntu14
    endpoint: my_acr_connection

But that doesn't work. I've also tried.

resources:
  - container: my_private_container
    image: ubuntu14
    endpoint: my_acr_connection

That too, didn't work.

resources:
  - container: my_private_container
    image: myregistryname.azurecr.io/ubuntu14
    endpoint: my_acr_connection

That didn't work either.

Can we please get updated docs with the proper way to do this?

We are hitting the same thing--we see the auth work but then see:

I hear that it's a server bug. @TingluoHuang is working on a fix.

[vtbassmatt]

Ting finished this work and he doc'd it as well.

[atrauzzi]

Where?

Thanks for the updated docs. That's great. I wasn't paying attention to them and tried writing out the image name a different way. The really odd thing was that the build went on for nearly 3 minutes, downloading docker images before saying "oh, I can't download this image. So what was it taking nearly 3 minutes downloading??

[AArnott]

Once I fixed my problem to match your documentation, it worked. But it took about 30 seconds longer coming from ACR than it took coming from docker hub, which is the opposite of what I was hoping for.

[AArnott]

I wonder if an ACR repository in a different azure region would improve performance. What region are the OSS builds happening in?

[TingluoHuang]

for your account, it's in azure CUS region

[AArnott]

Thanks. Adding a replication region to South Central US brought ACR perf up to Docker Hub levels -- but sadly, not beyond them. I guess I need to accept the 2:27 time to download the image with each linux build.

[TingluoHuang]

@AArnott we are working on pre-cache most of the populate linux container base images onto the Hosted Ubuntu 1604 pool. i think after that work is done, your docker pull will get faster. :D
