Mongodb Template

Install Docker

1. To create the container either navigate to the software_mil directory and run

docker-compose up -d

or

In the terminal:

run the following command to create the directory where the db data will be stored:

mkdir -p $HOME/docker/volumes/mongodb

run the following command to create a mongodb docker container:

docker run -d --rm --name mongod -p 27017:27017 -v $HOME/docker/volumes/mongodb:/data/db mongo

-d = run detached state
--rm = remove when container is closed
--name = set the container name
-p = set the port number that the container can be accessed with
-v = set the folder where all of the data from the container will be save note this is important to make sure all of the db data is persistent
mongo = will use the latest mongodb docker image to create container

2. run the following to find the hash for container:

docker ps -a

this will return a list of all containers. Find the one with the name you specified above after the --name tag and use the first three characters in the container ID.

ex:

CONTAINER ID   IMAGE     COMMAND                  CREATED             STATUS             PORTS                                           NAMES
e3c6f862ed27   mongo     "docker-entrypoint.s…"   About an hour ago   Up About an hour   0.0.0.0:27017->27017/tcp, :::27017->27017/tcp   mongod

3. run the following with your container id to start up the container:

docker exec -it e3c bash

4. once in the container you will run the command:

mongosh

5. next you will run the command:

use {name of database that you would like to create}

6. then after cloning this repo you will replace the connection information in the db.js file at line 3:

let uri = "mongodb://localhost:27017/{name_of_databse_you_created}";

7. run npm install in the terminal in the software_mil folder

8. then run npm start

you should be able to add to and read documents to the database by using api calls to http://localhost:8080/api
