SF Civil Grand Jury App

This repository contains the Code for San Francisco app for the San Francisco Civil Grand Jury project.

Getting Started

  1. Clone this git repo to a "local" directory (on your computer), then change into the directory.

    $ git clone https://github.com/dev-mission/sf-civil-grand-jury.git
    $ cd sf-civil-grand-jury
    
  2. There are some settings that must be configured to run the web application. They are set as "environment variables" which are loaded from a file called .env. Copy the example.env file as a starting point:

    $ cp example.env .env
    
  3. Install Docker Desktop: https://www.docker.com/products/docker-desktop

    1. If you have Windows Home Edition, you will need to install Docker Toolbox instead. See the troubleshooting notes below.
  4. Open a command-line shell, change into your repo directory, and execute this command:

    $ docker-compose up
    

    It will take a while the first time you run this command to build the "images" to run the web application code in a Docker "container". When you see messages that look like this, the server is running:

    server_1       | 2:14:26 AM web.1     |  > [email protected] start /opt/node/app
    server_1       | 2:14:26 AM web.1     |  > nodemon -V --ignore ./client ./bin/www
    server_1       | 2:14:26 AM web.1     |  [nodemon] 1.19.0
    server_1       | 2:14:26 AM web.1     |  [nodemon] to restart at any time, enter `rs`
    server_1       | 2:14:26 AM web.1     |  [nodemon] or send SIGHUP to 57 to restart
    
  5. Open ANOTHER command-line shell, change into your repo directory, then execute this command to log in to the running server container:

    $ docker-compose exec server bash -l
    

    Whenever the server container is running, you can execute this command to log in to the server- you will then be in a Linux "bash" command-line shell. Execute the following two commands inside the server container to complete the setup:

    # sequelize db:create
    # sequelize db:migrate
    # sequelize db:seed:all
    
    1. Before opening the app, you'll need to import some data into the database. Execute this command to import the seed data file:
    bin/import xlsx/seed.xlsx
    
  6. Now you should be able to open the web app in your browser at: http://localhost:3000/

    1. If you had to install Docker Toolbox, then replace "localhost" with the IP address of the Docker Virtual Machine.
  7. To stop the server, press CONTROL-C in the window with the running server. If it is successful, you will see something like this:

    Killing sfcgj_db_1           ... done
    Killing sfcgj_server_1       ... done
    Killing sfcgj_mailcatcher_1  ... done
    

    If it is not successful, you may see something like this:

    ERROR: Aborting.
    

    If you get an error, the server may still be running on your computer. To force it to stop, run the following command and wait for the output to report DONE:

    $ docker-compose stop
    Stopping sfcgj_db_1          ... done
    Stopping sfcgj_server_1      ... done
    Stopping sfcgj_mailcatcher_1 ... done
    
  8. That's it! After all this setup is complete, the only command you need to run to get started again is the docker-compose up command.

Shell Command Quick Reference

  • Every directory and file on your computer has a path that describes its location in storage. Special path symbols include:

    • The current working directory you are in: .
    • The parent of the current working directory: ..
    • Your home directory: ~
    • The root directory: / (Mac, Linux) or \ (Windows)
      • The same symbol is used as a separator when specifying multiple directories in a path
      • If the path starts with the separator, it means the path starts at the root
        • For example: /Users/myusername/Documents
        • This is called an absolute path
      • If the path does not start with the separator, it means the path starts at the current working directory
        • For example, if the current working directory is: /Users
          then the same path as the previous example is: myusername/Documents
        • This is called a relative path
      • A path can also start with any of the above special path symbols
        • For example, on Mac the same path as the previous example is: ~/Documents
  • To print the working directory (i.e. to see the full path of the directory you are currently in):

    $ pwd
    
  • To list the files in the working directory:

    $ ls -l
    
  • To change the working directory:

    $ cd path
    
  • To make a new directory inside the working directory:

    $ mkdir newpath
    
  • To create a new empty file inside the working directory:

    $ touch filename.ext
    

git Command Quick Reference

  • To check the status of the files in your local repo (i.e. what's been added or changed):

    $ git status
    
  • To add all the changed files to the next commit:

    $ git add .
    

    To add specific file(s) to the next commit:

    $ git add path/to/file1.ext path/to/file2.ext path/with/wildcard/*
    
  • To commit the added files with a message:

    $ git commit -m "My description of what's changed"
    
  • To push the commit to the remote repo:

    $ git push
    
  • To pull any new commits from the remote repo:

    $ git pull
    

Docker Command Quick Reference

  • To start all the containers:

    $ docker-compose up
    
  • To log in to the running server container:

    $ docker-compose exec server bash -l
    
  • To stop all the containers, in case things didn't shutdown properly with CTRL-C:

    $ docker-compose stop
    
  • To run the server container without starting everything using the up command:

    $ docker-compose run --rm server bash -l
    
  • To re-build the server container:

    $ docker-compose build server
    

Docker Troubleshooting

  • On some PC laptops, a hardware CPU feature called virtualization is disabled by default, which is required by Docker. To enable it, reboot your computer into its BIOS interface (typically by pressing a key like DELETE or F1 during the boot process), and look for an option to enable it. It may be called something like Intel Virtualization Technology, Intel VT, AMD-V, or some similar variation.

  • On Windows, Docker Desktop cannot run on Windows Home edition. Install Docker Toolbox instead:

    https://docs.docker.com/toolbox/overview/

    https://github.com/docker/toolbox/releases

    Use the Docker QuickStart shell installed with Docker Toolbox to open a command-line shell that launches Docker for you when it starts. On Windows, right-click on the shotcut and Run as Administrator. Note: this can take a long time to start, depending upon your computer, as it needs to start a virtual machine running Linux.

    The virtual machine will have its own, separate IP address on your computer. In the .env file (see step 4 in Getting Started), replace localhost with 192.168.99.100 in the BASE_HOST and BASE_URL variables. To confirm that this is the correct IP address, run this command in the command-line shell:

    $ docker-machine ip
