Laravel AWS Elastic Beanslack Deployment Error- Out Of Memory Error

I deployed my Application in AWS Elastic Beanslack. Intially I deployed my application directly in Aws console. After configuring all the things. I zipped my code and upload it in a console. At that time its working perfect.

But now I tried to deploy with cli, its shows error. I put eb deploy command

Creating application version archive "app-xxxxxxxxx".

From Internet I tried these all these things 1) I extended memory in php.ini but still its not working 2) I created ebextensions folder and do some configurations but thats also not working

My guess was Initially I deployed manually, so at that time I zipped with vendor folder also. Now when I tried with cli it wont take vendor folder. Instead of its by using composer install So I think I'm facing this issues due to these things

Please let us know, If any other thing I want to do

When deploy with ElasticBeanstalk (ELB) we should check Environment. With memory_limit, you can config this in Software tab (Configuration)

Follow:

1. Access the ELB
2. Open to your environment
3. Go to Configuration , then Software tab
4. Find the Memory limit field.
5. Change the value for what you want
6. Redeploy
