Environment handling for QED

temp_config first looks through a set list of environments in server_configs.json, then if a matching SERVER_NAME doesn't exist in that file, temp_config runs its original routine where it automatically determines the environment to use.

Current environment files

1. cgi_docker_*.env - environments for old cgi servers.
2. local_dev.env - local development without docker, outside epa intranet.
3. local_docker_dev.env - local development with docker, outside epa intranet.
4. local_epa_dev.env - local development without docker, with epa intranet access.

Adding a new environment

To add a new environment for server deployment, first add an entry to temp_config/server_configs.json file. Each entry has the following keys: SERVER_NAME, ENV, DESCRIPTION:

• SERVER_NAME - The server's name, which can be obtained from socket.gethostname() (Python), $HOSTNAME (Linux), or %COMPUTERNAME% (Windows), and assumes local if neither exist.
  
• ENV - The .env filename to point to for the server name.
  
• DESCRIPTION - Brief summary of server (optional).

Dynamically set env vars in python code:

from temp_config.set_environment import DeployEnv

runtime_env = DeployEnv()
runtime_env.load_deployment_environment()  # set env vars based on network access

To set .env with a shell script, run:

Linux: . set_env_vars.sh env_filename.env
Windows: set_env_vars.bat env_filename.env
