We are running Azure IOT pipelines on our self-hosted Windows agents. Unfortunately it is throwing following error during the build pipeline
ERROR: ('Could not connect to Docker daemon. Please make sure Docker daemon is running and accessible', DockerException("Error - while fetching server API version: (5, 'CreateFile', 'Access is denied.')"))
It seems we need to add some permissions for agent service.
We have installed Docker manually and Docker service is running with localsystemAccount.
Azure Pipelines agent service is running with Network Service.
finally issue got resolved after running the pipeline agent service with the same user that docker service is running on.
