Command arguments Quotations not visible in Linux agent logs

[vithati]

I am using docker run task to execute a one liner script in a container just build in the pipeline. The idea is to execute:

docker run -t my-container sh -c "ls .Test/.csproj | xargs -L1 dotnet test -c Release --logger:trx -r ../../test_out"

So I set up a docker run task and pass sh -c "ls .Test/.csproj | xargs -L1 dotnet test -c Release --logger:trx -r ../../test_out" in the field Command.

To my surprise, the double quotes disappear and there fore the actual command executed by the agent is (from the task output)

docker run -t my-container sh -c ls .Test/.csproj | xargs -L1 dotnet test -c Release --logger:trx -r ../../test_out

There is no failure in executing command, just quotation not visible in logs.

In windows agent, logs showing properly. docker run -t my-container sh -c "ls .Test/.csproj | xargs -L1 dotnet test -c Release --logger:trx -r ../../test_out"

I looked at code https://github.com/Microsoft/vsts-task-lib/blob/f22b24bd393becbb370b95f394e3f2cdcc823964/node/toolrunner.ts , looks like for linux, quotations not handled like windows.

I can't say for sure, but if you are passing that in as a string it could be an issue with _argStringToArray. If so, passing something like docker run -t my-container sh -c "\"ls .Test/.csproj | xargs -L1 dotnet test -c Release --logger:trx -r ../../test_out\"" should solve it. Right now, it sees that you have quotes and thinks that you just want to avoid splitting it up into different args (which I assume is true). Escaping should fix that.

If that doesn't resolve it, I'll take a deeper look - I'm somewhat confused as to why it would work with Windows and not Linux

I'm not sure if it's the right place to report this, but escaping seems to be inconsistent:

Here is the Docker task I'm using in the classic release pipeline:

• UI

• YAML

steps:
- task: Docker@2
  inputs:
    command: run
    arguments: '{\"version\": \"$(Build.BuildNumber)\"}'

As you can see, I'm trying to pass a JSON as string (all other arguments are omitted for clarity) and it's not escaped correctly when task is run:

[command]/bin/docker run {\version": "1.2.3"}
/bin/docker: invalid reference format.
