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 4- | rev)
export DB_HOST=10.10.10.11 # The host inside my overlay
export DB_PORT=27017 # this should be changed to something a little more discrete
export DB_NAME=$KOAD_IO_ENTITY

export INIT_ROOT_USERNAME=koad
export INIT_ROOT_PASSWORD=$(cat /dev/random | tr -dc '[:alnum:]' | head -c 40 2>/dev/null | base64 -w 0 | rev | cut -b 4- | 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=$DB_USER_PASS && \
echo INIT_ROOT_PASSWORD=$INIT_ROOT_PASSWORD && echo

may as well print it all out, so you can copy it somewhere safe. 

echo && echo && echo KOAD_IO_ENTITY=$KOAD_IO_ENTITY && echo INIT_ROOT_USERNAME=$INIT_ROOT_USERNAME && echo INIT_ROOT_PASSWORD=$INIT_ROOT_PASSWORD&& echo DB_USER_NAME=$DB_USER_NAME && echo DB_USER_PASS=$DB_USER_PASS && echo DB_HOST=$DB_HOST && echo DB_PORT=$DB_PORT && echo DB_NAME=$DB_NAME  && echo

maybe you want to use this as a state DB for a koad:io entity? .. paste output of the previous command 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 $DB_NAME -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

as admin

create the DB and shit, use this page as guidance

mongo --host $DB_HOST:$DB_PORT -u $INIT_ROOT_USERNAME -p $INIT_ROOT_PASSWORD --authenticationDatabase admin

as user/entity

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"
mongo --host $DB_HOST:$DB_PORT -u $DB_USER_NAME -p $DB_USER_PASS --authenticationDatabase $DB_NAME

hmmm..

Maybe my shit is too old,.
