GNU/Linux OpenShift Where is My Secret Used?

A simple bash-script for OpenShift to determine which deployment configs make use of a specific secret (within the active project).


oc get dc -o custom-columns=",readyReplicas:status.availableReplicas,Volumes:spec.template.spec.volumes,env:spec.template.spec.containers[].env,envFrom:spec.template.spec.containers[].envFrom,Volumes:spec.template.spec.volumes" | grep -E "($1)" | grep -oE "^[a-z0-9-]{3,99}"

$ secretname

PowerShell Function To Add Filesystem Permissions

Recently wrote a simple function to add permission to filesystem resources. It defaults to modify permissions, but can also be another basic permission for instance: Read, Write or FullControl.

function fnAddFilesystemPermissions()
  param (
	[string]$sPermission = "Modify"

  # Add write permissions to a file using powershell...
  $accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule($sUserName,$sPermission,"Allow")
  $acl = Get-ACL -Path $sPath
  $acl | Set-Acl -Path $sPath

  # Return permissions...
  return (Get-ACL -Path $sPath).Access | Format-Table 

PS> fnAddFilesystemPermissions -sPath “C:\Path\To\Resource” -sUserName “User-Principle-Name” [-sPermission “FullControl“]

[Other] Start DevOps Tools From Command line

Some commands I regularly use to start tools from the command line when I need them to start with elevated privileges.
