How to install php composer extension on azure web app?

Question

My existing Azure Web App is running on Linux PHP Laravel. I successfully deployed the app from bitbucket but I still need to install and run composer update inside azure web app.

The extension option in Deployment tool is disabled/grayed out.

Running kudu says that data persist only on /home. So where to install composer and allow it to run?

Hi @Nelson Mendaros ,

Your app service should run composer if you're utilizing build automation.

However, once you're SSH'd into your app service:

1. Create an ext directory inside /home/site and download composer into that directory: mkdir /home/site/ext cd /home/site/ext curl -sS https://getcomposer.org/installer | php
2. Once installed, you can run it locally but to access globally, it needs to be added into /usr/local/bin/composer during app startup. To do that, create startup.sh under /home using vi startup.sh (press "i") and add cp /home/site/ext/composer.phar /usr/local/bin/composer and save (press "Esc" then ":wq!")
3. Change the Configuration > General Settings Startup Command to /home/startup.sh
