Mongo db

setup

set some enviroment variables, then the following commands would work out of the box. 

export KOAD_IO_ENTITY=marsha
export DB_USER_NAME=$KOAD_IO_ENTITY
export DB_USER_PASS=$(cat /dev/random | tr -dc '[:alnum:]' | head -c 40 2>/dev/null | base64 -w 0 | rev | cut -b 2- | rev)
export DB_HOST=10.10.10.11 # The host inside my overlay
export DB_PORT=27017
export DB_NAME=$KOAD_IO_ENTITY

export DB_ROOT_INIT_USERNAME=koad
export DB_ROOT_INIT_PASSWORD=$(cat /dev/random | tr -dc '[:alnum:]' | head -c 40 2>/dev/null | base64 -w 0 | rev | cut -b 2- | rev)

if you use the previous commands, you should also print out the passwords rthat were generated. 

echo && \
echo "generated two passwords, copy and paste them somewhere safe!" && \
echo DB_USER_PASS=$DB_USER_PASS && \
echo DB_ROOT_INIT_PASSWORD=$DB_ROOT_INIT_PASSWORD && echo

maybe you want to use this as a state DB for a koad:io entity? .. paste the the passwords in the entity's .env file. 

echo && echo "$KOAD_IO_ENTITY's .env file > $HOME/.$KOAD_IO_ENTITY/".env && echo

I'll use my personal overlay for DB_HOST, this way nobody can connect to it unless they are inside my metaverse. maybe auth is optional here, since maybe I am the only one with access to the overlay. hmm.

create

your DB using docker, 

docker run --name $KOAD_IO_ENTITYs-mongodb -d -p $DB_HOST:$DB_PORT:27017 -v /home/koad/.$KOAD_IO_ENTITY/database/mongo:/data/db -e MONGO_INITDB_ROOT_USERNAME=$INIT_ROOT_USERNAME -e MONGO_INITDB_ROOT_PASSWORD=$INIT_ROOT_PASSWORD mongo

connect

use this to find out your string MONGO_URL=mongodb://DB_USER_NAME:DB_USER_PASS@DB_HOST:DB_PORT/DB_NAME 

echo "MONGO_URL=mongodb://$DB_USER_NAME:$DB_USER_PASS@$DB_HOST:$DB_PORT/$DB_NAME"

connect via another container 

docker run -d --name MYAPP -e MONGODB_CONNSTRING=mongodb+srv://username:password@clusterURL MYAPP:1.0

hmmm..

Maybe my shit is too old,.
