Wrong mount point spec for Windows Containers in Docker

      It seems that ":z" volume bind mount flag in docker is not suported for windows containers.

      For jenkinsfile:

      pipeline {
          agent {
              docker { image 'mksondej/aspnet-node-msbuild' }
          stages {
              stage('Test') {
                  steps {
                      powershell 'ls'

      Here's what my pipeline tries to execute:


      docker run -t -d -u 18:18 -w "C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA" -v "C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:rw,z" -v "C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA@tmp:C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA@tmp:rw,z" -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** -e ******** mksondej/aspnet-node-msbuild cat


      and the result is:


      java.io.IOException: Failed to run image 'mksondej/aspnet-node-msbuild'. Error: docker: Error response from daemon: invalid bind mount spec "C:\\Program Files (x86)\\Jenkins\\workspace\\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:C:\\Program Files (x86)\\Jenkins\\workspace\\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:rw,z": invalid volume specification: 'C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:C:\Program Files (x86)\Jenkins\workspace\test1_master-X2GYJHOEIWFTSVMPO3GB3GYF3NB4R7IFICRXKGCY7NVNWOUOC5QA:rw,z'

      It seems that running windows containers in the pipeline is currently impossible?

      By manually fiddling with the command above I've found out that without ":z" ("rw" can stay) it would work properly. I've tried to make a crude workaround by making a bat cmd somewhere in my PATH which would make a simple string replacement, but it only worked from my or other user's command line. The pipeline seems to run docker.exe directly.

      Any wokaround would be more than welcome, thanks
