I have tried to run 'composer update' command inside docker container in Aws ec2 instance. But I get this error 

  mmap() failed: [12] Cannot allocate memory

  mmap() failed: [12] Cannot allocate memory

  Fatal error: Out of memory (allocated 478179328) (tried to allocate 20996408 bytes) in phar:///usr/local/bin/composer/src/Composer/Util/RemoteFilesystem.php on line 462

I have tried using "memory_limit = -1" or "memory_limit = 2G" in the php configaration file. I have also tried to run this command "php -d memory_limit=-1 /usr/local/bin/composer update" inside my docker container. But it still shows the same error

Run composer update in your local environment, then commit composer.json and composer.lock to your code repository, pull the changes in your ec2 instance and run composer install.

Commonly, low resource servers don't have enough RAM to run composer update. You're better off doing it in your local environment, and only using composer install on your server.

    Don't run `composer update` inside the container. That's your problem, and there's no real point. Run `composer install` instead. – Joundill May 13 '20 at 08:52
