How to config AWS credential to ECR output

[emersonramos]

Hi folks,

I deployed buildkit using kubernetes - deployment+Service and I have a pipeline to build images using this one.

I didn't understand how to config AWS Credential to output the image to ECR. I'm using this command:

buildctl --addr tcp://buildkitd:1234
build --frontend dockerfile.v0 --local context=. --local dockerfile=.
--output type=image,name=<ECR_URL>/REPO:TAG,push=true

And I get this error: 401 Unauthorized

I tried to config the AWS credential on pipeline, but I get the same error.
