暂时将图像存储在弹性beanstalk api上

Question

I have a PHP API that will be hosted on Elastic Beanstalk. The user uploads images to this API. Once the API gets it, in PHP I store the file in a temp folder, then resize it to multiple sizes then upload it to an S3 Bucket.

It works locally but I haven't put this live yet. Is this possible to do once it is on an elastic beanstalk instance? I know I have to give write permissions to the temp_image directory when I work with it locally so do I have to do this when it's live on elastic beanstalk? If so, how do I manage folder directories on an elastic beanstalk? And will I have to do this every time I update my API?

Another solution I thought of is having a temp_image S3 Bucket and working from that?

Any suggestions would be great thanks!

ElasticBeanstalk deployments are considered immutable post-deployment, so you will probably have to change permissions on your temp folder. Thankfully, doing so is pretty straightforward. The mechanism for performing operations such as chmod or chown is through configuration files, described here. ElasticBeanstalk configuration files are invoked as part of a deployment, so the permissions should be applied automatically every time you update your API.

In your case, you would use something like this:

.ebextensions/01-make-temp-folder-writeable.config

container_commands:
  chown_folder:
    command: "chown webapp temp_image"
  chmod_folder:
    command: "chmod 775 temp_image"

Make sure you pay attention to your indentation - YAML files are very sensitive to whitespace.
