I'm currently setting up GitLab CI/CD. The Runner is installed on a Windows Server 2019 VM which has Docker Engine running. My gitlab-ci.yml looks something like this:
variables:
GIT_STRATEGY: clone
GIT_DEPTH: 0
stages:
- export
export:
stage: export
image: mcr.microsoft.com/dotnet/core/sdk:3.1
tags:
- myrunner
script:
- COPY . ./
- 'curl --location --output artifacts.zip --header "JOB-TOKEN: $CI_JOB_TOKEN" "https://git.myinstance.de/api/v4/projects/1234/jobs/artifacts/master/download?job=backend"'
- tar -xf artifacts.zip
- publish.bat
But before the script even starts getting executed, the following error message gets displayed:
ERROR: Job failed (system failure): Error response from daemon: container abc123 encountered an error during hcsshim::System::CreateProcess: failure in a Windows system call: The system cannot find the file specified.
It also prints out a ton of extra info, the most useful of which is probably this:
"CommandLine":"powershell -NoProfile -NoLogo -InputFormat text -OutputFormat text -NonInteractive -ExecutionPolicy Bypass -Command -"
What I'm getting from this is that the Runner tries to start a Powershell inside the container but fails. This is no surprise, as in the .Net Core 3.1-Image, Powershell has to be startet with the command pwsh. I looked at the yaml-reference for the gitlab-ci.yml file, but couldn't find a way to change the shell which the script gets executed with. What's even more confusing: When I replicate the script in a Dockerfile and build it manually on Runner, it works perfectly, as it is using CMD instead of Powershell to run the instructions.
I really don't know from which angle to take this. I'm not trying to start a Powershell from my script, I'm not using Powershell-exclusive commands and I can't tell the Runner to not use Powershell.
Note: I'm not quite sure if this question would belong to Server Fault or Super User, as I'm using free software in a professional environment. But it seems as the relevant tags have more questions and watchers on this site, so I'm trying my luck here.
