Deploy the docker compose

  1. First create a .env file locally. Please refer to the file .env.template for all the variables that need to be added.

  2. There are three secrets, please ask one of the code owners for these secrets to add them to your .env file

  3. (If you are on macOS) Copy the init-mongo.js into ~/

cp ./init-mongo.js ~/init-mongo.js
  1. Run docker compose down to remove all the images and stop all the containers running

If you do not want to remove the attached mongodb volume:

docker compose down --rmi all

If you want to remove the attached volume

docker compose down --rmi all -v
  1. Run docker compose up with the --no-deps flags to rebuild the images
docker compose up -d

Troubleshooting the deployment

Flask (503):

  • The issue is quite possible with mongo
  • Run the following code to hard-reset the system (NOTE: This should be done with extreme care and ONLY WHEN NECESSARY as it deletes volumes)
docker compose down --rmi all -v

Managing the private key

The PRIVATE_KEY in the .env file needs to be base64 encoded

$(cat <<location of the pem file>> | base64)

Backup a Mongo Container

The following section describes how to backup the mongodb container

  1. Export the variable in the .env to the terminal
set -a
source .env
set +a
  1. Start the backup
mongodump --host=localhost:$MONGO -u=$MONGODB_INITDB_ROOT_USERNAME -p=$MONGODB_INITDB_ROOT_PASSWORD -d=$MONGODB_INITDB_DATABASE -o="<Backup location>"

The following commands describe how to restore the backup

  1. Export the variable in the .env to the terminal
set -a
source .env
set +a
  1. Start the backup restoration
mongorestore --host=localhost:$MONGO -u=$MONGODB_INITDB_ROOT_USERNAME -p=$MONGODB_INITDB_ROOT_PASSWORD
