Sending email notifications

You could use this tool to send you a email notification as and when the new slots are available. Use the following commands to set it up.

1. Uses Google's smtp server by default smtp.google.com
2. You should have your email (gmail) and password from which you would want to trigger an email from
3. You should provide the email to which you want to trigger notification to
4. Setup these details as environment variables as shown below

export JABF_SMTP_EMAIL=jabfinderindia@gmail.com  # Replace the email with your email
export JABF_SMTP_PASSWORD=xxx                    # Replace xxx with the password
export JABF_NOTIFY_TOEMAILLIST=abc@xyz.com       # Replace abc@xyz.com to the email to which you want to send notifications to.

# Runt he following command in the same shell where you have set these environment variables

./jabfinder check --districtCode 294 --age 45 --notify

If you want to send notifications to multiple addresses, separate them by commas. E.g. - 
export JABF_NOTIFY_TOEMAILLIST=abc@xyz.com,def@xyz.com

You may face errors sending email based on your smtp email account settings. Please check the Google's documentation to enable the use of SMTP on your email based on your preferences.

Finding district code

./jabfinder districts

This lists all valid states and asks you which state you want to look up districts for

If you already know your state code, you can use -

./jabfinder districts -s 36

Find the code to the corresponding district you want to check availability for and use it in the jabfinder check command.

Using Docker

You would have to pass environment variables for SMTP config.

Create a .env-file locally with the following and replace the values accordingly

JABF_NOTIFY_INTERVALINSECONDS=300
JABF_SMTP_EMAIL=abc@xyz.com
JABF_SMTP_PASSWORD=xxx
JABF_NOTIFY_TOEMAILLIST=abc@xyz.com

1. Using published image

Pulls the image from dockerhub

docker run -it --name jabfinder --env-file=.env-file vatsakatta/jabfinder:1.0.0 ./jabfinder check -d 294 -a 18 -e 1 -n

2. Building Locally

You can build the docker image using the following command

docker build . -t jabfinder

3. Running Local Build

Run the docker image built using above command with the necessary parameters

1. Pass in the command arguments along with docker run

   docker run -d --name jabfinder --env-file=.env-file jabfinder:latest ./jabfinder check -d 294 -a 18 -e 1 -n
   
   ## The above command will check for open slots every 5 minutes for the age limit > 18 and dose 1 and sends a mail to abc@xyz.com
   

2. Verify if the jabfinder is running in docker using the logs

   docker logs -f jabfinder
