Kudu: Equalize PHP Modules between Kudu Linux Containers and App Service Linux Containers

[garimpeirodouniverso]

Hello.

I think this behavior was already mentioned in other issues (#2702 and #3112 ). Basically, it is important that the PHP modules available to the Linux App Service container on Azure should be also available under the Kudu Container as well, in order to avoid deployment issues.

In my example below, I am able to run this command (php artisan migrate) via SSH on the Linux App Service; however, the same cannot be said when running this very command via Kudu Bash. I also tried via deploy.sh script and also via Post Deployment Action on a DevOps Pipeline AzureRmWebAppDeployment@4 action.

This command will fail because on the Kudu container there is no "sqlsrv" PHP module installed, as opposed to the Linux App Service container. Actually there are several other modules missing on Kudu that are present in App Service, we can see it clearly when running the command "php -m" on both, here are the results:

• php -m on Linux App Service SSH:

"Artisan Migrate" is an important post deployment action in any Laravel project, hence should be possible to execute it via Kudu container. So equalizing all the PHP Modules between both would resolve this issue (or at least equalizing all the SQL related modules).

Thanks

Repro steps.

login on Azure Portal > App Services > select your (linux PHP) App Service > Advanced tools > Go
select "Bash" and run the following commands
cd /home/site/wwwroot
php artisan migrate --force

The issue is still present and filling up my error logs unnecessarily.

Will this ever be fixed?
