root@philUbuntu1804:~/AzureAcrContainer/src# az version { "azure-cli": "2.22.0", "azure-cli-core": "2.22.0", "azure-cli-telemetry": "1.0.6", "extensions": {} }

How to reproduce it:
1) Decompress the attached package 'AzureAcrContainer.zip' and upload to your Linux machine with az cli installed.
2) Run command as below: az cloud set -n AzureChinaCloud az login az acr login -n "'your azure container registry'"

cd ~/AzureAcrContainer/src az acr build --registry "'your azure container registry'" --file Dockerfile --image ssmr/api-test:0.1.8 ./ You will see the errors pasted above and also attached.

Comparison test:

1. docker build -t aa:v1.1 ./ It executes successfully without any errors.
2. Delete '--no-restore' option in Dockerfile, and then run 'az acr build --registry "'your azure container registry'" --file Dockerfile --image ssmr/api-test:0.1.8 ./'.

It will also successful without any errors.

Please PG help check:

1. Why does the az acr build failure occur? (Also tried on az ali 2.30.0, it also failed. )
2. Please tell the difference between 'az acr build' and 'docker build' in underlying mechanisms.

Hi @yonzhan and @service team,
May I have an update about this issue? Thanks.

[yonzhan]

container registry service team could help with

[huanwu]

@caiwan-msft Could you add bin and obj directories into .dockerignore file to avoid the lingering files and try again?

[northtyphoon]

@caiwan-msft specifically you need to change src/.dockerignore file in the sample project and remove the trailing slash. It will make az acr build ignore the corresponding folders when package and upload for build.

**/bin/
**/obj/

to

**/bin
**/obj

[caiwan-msft]

Thank you for your reply and confirmation, and I will have a try and then give you the result.

BTW, why does 'docker build' succeeds, but 'az acr build' fails? What' s the difference between 'az acr build' and 'docker build' in underlying mechanisms?

[caiwan-msft]

Verified solution successfully.

Hi @huanwu and @northtyphoon ,
Thank you both help on this issue.

In my opinion, there should be no difference between '/bin/' and '/bin'.

May I know what is the reason of the solution, just the difference between '/bin/' and '/bin' in this issue here?
Thanks.

[caiwan-msft]

Get reply from @northtyphoon : 'az acr build' doesn't support trailing slash in the ignore. It' s just the restriction of 'az acr build'.

Thanks.
