container_commands fail to migrate Django database

If I remove the following:

container_commands:
  01_migrate:
    command: "source /var/app/venv/*/bin/activate && python manage.py migrate --no-input"
    leader_only: true

The app gets successfully deployed.

When I eb ssh and try to run python manage.py migrate I get the following error:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    main()
  File "manage.py", line 18, in main

  File "/usr/lib64/python3.8/os.py", line 675, in __getitem__
    raise KeyError(key) from None
KeyError: 'RDS_DB_NAME'

I looked at a lot of the answers posted and have tried almost all the solutions given. I still get the same errors.

How could I resolve this?

Your error suggests that EB is having difficulties with finding your environment variables. During deployment, these environment variables are available. When ssh'ing into your instance however, you will have to import them manually. You can find the documentation here

One way to do this is to use the get-config tool, which is located at /opt/elasticbeanstalk/bin/get-config.

You can use the following command to print your environment variables:

/opt/elasticbeanstalk/bin/get-config environment

However, you still need to export them. This can be done with the following command:

export $(/opt/elasticbeanstalk/bin/get-config environment| xargs)

Now Django should be able to find the environment variables as set in your EB environment.

Alternatively, you should also be able to export you environment variables via:

export $(cat /opt/elasticbeanstalk/deployment/env | xargs)
