I have uploaded Django app on azure server web app using Zip Deploy with FTP. After deploying it gives error that "sndlibrary not found" so i need to go to ssh and install it manually by using command apt update && apt-get -y install libsndfile1-dev.So The problem is that whenever the app(container) gets restarted it again shows the same error and i again need to install the package from ssh.The package does not persist on restart.So is there any way to persist the package on app restart?

I have also tried using startup.sh script on the wwwroot path but when run it shows error that "could not locate the package".

startup.sh :

Every time you restart the container, if the image is rebuilt, the packages are installed from your requirements.txt file. What you have to do is simply adding it to your requirements.txt file. You can do that either manually, or with the command pip freeze.

If you're using docker the command is

docker exec <container_name> pip freeze > requirements.txt

Otherwise if you are inside the runtime environment (Azure VM or docker container) just pip freeze > requirements.txt will do.

You get the could not locate the package error when trying to install your package because apt-get update wasn't successful: invalid operation update. I'm not familiar with azure web app service but the problem might come from either:

• You running *apt* update and then *apt-get* install which should be fixed by using apt or apt-get for both commands.
• Azure preventing you from running apt update
• An issue with apt. Maybe check that the user running startup.sh has the right permissions ?
