GitLab CI Warning: "git": executable file not found in $PATH

in 
WARNING: current commit information was not captured by the build: git was not found in the system: exec: "git": executable file not found in $PATH

I saw this WARNING sail by while I was watching a Docker build process run on my GitLab CI pipeline. The build wasn’t failing but wasn’t completing cleanly. The GitLab runner image being used for this pipeline was:

image: python:3.9-slim

The solve came after a bit of experimentation and found that I needed to edit my .gitlab-ci.yml file to include the following:

before_script:
  - apk add --update --no-cache git

That edit solved the Warning and cleaned up the pipeline. Noted.

How to shut down VirtualBox / Vagrant from CLI

in ,

So you need to stop one or more running VirtualBox instances that you may have started and are hanging around. Here are a few helpful commands:

List all running machines (returns name and UUID)
VBoxManage list runningvms

Stop running VMs by "hibernating" them (recommended to avoid data loss)
VBoxManage controlvm <name|uuid> savestate

Poweroff running VMs (not recommended because we may lose data in the guest)
VBoxManage controlvm <name|uuid> poweroff

Use ACPI in an ACPI-aware guest OS (preferable to poweroff for graceful shutdown of guests)
VBoxManage controlv m <name|uuid> acpipowerbutton
