AWS Elastic Beanstalk Python Application ebextenstions pip install command failed

Question

Hi I am deploy an EB Python Web Application to a private VPC without internet access. I will install python dependency packages offline.
I have all the packages ready together with application file.

```
application.py
packages/*.whl
packages/requirements.txt (CONTENT will be those whl packages name)
.ebextensions/python_packages.config
...
OTHER_VENV_RELATED_FOLDERS
```
The `ebextensions/python_packages.config` content:
```
commands:
  use_python_venv:
    command: source /opt/elasticbeanstalk/deployment/env
  install_python_requirements: 
    command: pip install --no-index --find-links /var/app/current/packages -r /var/app/current/packages/requirements.txt
```
The application tested working on my local computer and I zipped `application.py`, `ebextensions` and `packages` folder into one zip file and upload and deploy into one single instance with EIP.

it gets the below failed message in `/var/log/cfn-init-cmd.log` on the AMI EC2 instance. (python3.8 runtime)
```

```
I checked the path of the `requirements.txt` file and it is not there and here is the directory and files under that `/var/app` directory:
```
staging/Pipfile
venv
```

It means the `/var/app/current` directory not get created so my command failed. Where is my package file during the staging process?

How can I install offline python dependency packages on ElasticBeanstalk EC2 instance without internet access? Edit `Pipfile` instead? Thank you

Answer

resolved the issue by putting an empty `requirements.txt` in the working folder and move all `whl` binary pkgs and `requirements.txt` file with those pkg info to the `packages` subfolder. Then used `container_commands` to do the trick.

```
container_commands:
  01_install_python_packages:
    command: "$PYTHONPATH/pip install --no-index --find-links ./packages -r ./packages/requirements.txt"
```
