Resolved: Fix SSL renewal issue on Gitlab Server

on
PROBLEM : I had hosted a gitlab server on Azure and it was not getting autorenewed. SOLUTION :  1. Check the current SSL cert path: sudo grep -n "ssl_certificate" /var/opt/gitlab/nginx/conf/gitlab-http.conf OR sudo grep -n "ssl_certificate" /etc/gitlab/gitlab.rb  You are likely to see something like this: nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.example.com.crt" nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.example.com.key"  2. In my case, I was using gitlab let'sencrypt. So, I installed certbot. sudo apt update && sudo apt install certbot -y  3. Obtain Fresh Certificate sudo gitlab-ctl stop nginx sudo certbot certonly --standalone -d gitlab.yourdomain.com sudo gitlab-ctl start nginx 4. Configure Gitlab to use new cert external_url "https://gitlab.yourdomain.com" letsencrypt['enable'] = false nginx['s...

Resolved Error - Azure Powershell failed to get token from Token Cache. Getting You cannot call a method on a null-valued expression

on

 Recently, I was working on an Azure Powershell Script in which I was getting the Cached Token and it was working fine for a long time and it started failing recently.

Here is the code that I was using in my powershell script:

    Write-Host "Getting Az Context"
    $azContext = Get-AzContext
    Write-Host "Displaying context"

    #$rmAccount = Add-AzureRmAccount -SubscriptionId $subscriptionId 
    #$tenantId = $azureRmContext.Tenant.Id
    $tokenCache = $azContext.TokenCache
    $cachedTokens = $tokenCache.ReadItems() `
        #| where { $_.TenantId -eq $tenantId } `
        Sort-Object -Property ExpiresOn -Descending
	
    $cachedTokens[0].AccessToken

Now, I started getting the error "You cannot call a method on a null-valued expression". I was clear that my Token Cache is getting expired and then I googled about the issue and I find the following useful github links: And finally, I implemented the following solution:

Solution: 

    $currentAzureContext = Get-AzContext
    $azureRmProfile = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile;
    $profileClient = New-Object Microsoft.Azure.Commands.ResourceManager.Common.RMProfileClient($azureRmProfile);
    $profileClient.AcquireAccessToken($currentAzureContext.Subscription.TenantId).AccessToken;
