Ability to pass --env-file argument in docker-compose

[earthslasthope]

The issue I'm having is I can't see a way to pass a custom env-file in Visual Studio when debugging my docker-compose project. I can see there is a DockerfileRunEnvironmentFiles property that allows doing this for single projects (docker run) but there is nothing similar for docker-compose. Furthermore, I can't find a documented way to pass any custom options that come after docker-compose before the commands which would take care of this (e.g. docker-compose --env-file my_vars -f docker-compose-custom.yml up).

Are there any options to accomplish this? Can I customise how the docker-compose command gets built?

For your reference I was looking at the documentation here https://docs.microsoft.com/en-us/visualstudio/containers/docker-compose-properties?view=vs-2019

Hi @tthordarson ,
Additional arguments to the docker-compose up command can be passed through DockerComposeUpArguments property.
That being said, I tried --env-file with DockerComposeUpArguments, but --env-file needs to be passed before up as opposed to after up.
I am investigating how this could be achieved.

Pratik Sanglikar (@pratiksanglikar) Any update on the investigation about passing the custom env file as argument to docker compose up ?

[pratiksanglikar]

Hassaan Ahmed (@syedhassaanahmed), it is an item on our backlog, but with the current priorities, there is no specific date when we can get to it.

Anton Shakalo (@CriggerMarg) this remains on the backlog (now assigned to me) and is actually getting fairly close to the top.

Hello,
any news on this one ?

Currently the command generated by VS adds the "--env-file" option after the "up" command:
up -d --env-file .env.dev

resulting in an error:

C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Sdks\Microsoft.Docker.Sdk\build\Microsoft.VisualStudio.Docker.Compose.targets(402,5): error DT1001: unknown flag: --env-file
C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Sdks\Microsoft.Docker.Sdk\build\Microsoft.VisualStudio.Docker.Compose.targets(402,5): error DT1001: If the error persists, try restarting Docker Desktop.

Maybe there is a workaround ?

Sorry for the delay, this has now reached the top of the backlog and a fix is out for review. I still don't have a timeline for when the fix will be available, but it is in progress.

Thanks Nathan Carlson (@NCarlsonMSFT) Test on visual studio 2022 preview 4 but still getting the same message unknown flag: --env-file adding this <DockerComposeBuildArguments>--env-file .env</DockerComposeBuildArguments>

[NCarlsonMSFT]

Sorry Raúl Flores (@raulidavid), I was flitting through too many things yesterday and omitted telling you that there is a new MSBuildProperty to support this:
<DockerComposeEnvFilePath>myawesomefilename.env</DockerComposeEnvFilePath>

[raulidavid]

thanks Nathan Carlson (@NCarlsonMSFT) now it's working!!

Nathan Carlson (@NCarlsonMSFT) how about updating documentation https://learn.microsoft.com/en-us/visualstudio/containers/docker-compose-properties ?
