Docker Prerequisites

Install docker. On linux, you may have to install docker-compose separately.

On Windows, all terminal docker commands need to be run using Windows PowerShell, not Command Prompt. PowerShell comes with Windows.

Setup and running the server: Linux or Mac

This project uses these GitHub conventions to provide convenient scripts for developers.

On a fresh clone of this repo, run:

$ script/setup

This will download and build all the docker images used in this project. It will also build the map tile data supporting the tileserver service. This step can take a long time complete. Its output should end with something like the following, which will eventually get to 100%, I promise.

...
> wwww features, xxxx bytes of geometry, yyyy bytes of separate metadata,
zzzz bytes of string pool
> 99.9% 11/2222/3333

Make It Go

Just run:

$ script/server

Use ctrl-c to stop.

(Alternatively, the server can be started in detached mode with script/start. In that case, stop it with script/stop.)

Once rails fully starts up, you can view the running app at localhost:3000 or an alternative port specified in .env if one exists. See .env.example for available options and reasonable starting values.

To monitor the console output from just the rails app and not the other docker containers, run:

$ script/logs

Updating the App

After a git pull or any time ruby gems or node modules may have changed, run:

$ script/update

Then restart the app with script/server (or script/start).

Development

Most developer contributions will be focused on the rails app. Because this project uses docker, we already have a uniform ruby/rails development environment in our rails docker image. Any time you need to run a rails command you should do so from a running docker container to take advantage of this consistent environment. Use the following command to open a bash console on the rails container:

$ script/console

Now you can treat this console like any other development environment, running rails or bundler commands as needed. Please refrain from running such commands in your local environment. Always use the rails container instead.

Any changes to source files should be made directly in your local filesystem under the /rails directory using your preferred editing tools.

Setup and running the server: Windows

Step 1: build the app

In your terminal program, navigate to the directory where you put the terrastories-minimal files, after you've downloaded it. You always have to be in this directory to run any of the docker commands. Run docker-compose-build.

Docker will automatically build images as needed when running docker-compose build, but to confirm everything builds correctly, run the following and check that the output ends with something like this.

$ docker-compose build
  ...
> mariadb uses an image; skipping
  ...
> Successfully built 0123456789
> Successfully tagged terrastories/tilebuilder:latest
> tileserver uses an image; skipping

Step 2: build the map tiles

The tilebuilder service will need to be run once to populate the mbtiles shared volume that the tileserver will read from. The tilebuilder does not need to stay running along with the other services. Building map tiles may take quite a long time, but it should show progress similar to the following and eventually get to 100%, exiting with code 0.

$ docker-compose run tilebuilder
...
> wwww features, xxxx bytes of geometry, yyyy bytes of separate metadata,
zzzz bytes of string pool
> 99.9% 11/2222/3333

Any time the shapefiles change and require regenerating the mbtiles file, this service will need to be run again and the tileserver restarted once the tilebuilder finishes (just run docker-compose restart tileserver).

Step 3: Make It Go

In docker-compose.yml, the tileserver service is listed as dependencies for the nginx service. So to start the whole thing up (omitting tilebuilder, which only needs to run once) just run the following.

$ docker-compose up -d nginx

Once the service fully starts up, you can view tileserver running at localhost:3000 or an alternative port specified in .env if one exists. See .env.example for available options and reasonable starting values.

To view a map equipped with bookmarks and other customizations, visit localhost:3000/map/.

Omit the -d flag if you prefer to see the nginx server output. You can always tail the output of any service with docker-compose logs.

To spin all the services back down run the following.

$ docker-compose down

Creating (and updating) the Map

Step 1: preparing content in Mapbox Studio

Terrastories is designed to render a basemap as designed and styled in Mapbox Studio. There are two different components: shapefiles (the spatial data without any styling properties) and styles (the look and feel of the map, as designed in Mapbox Studio, exported in json format). The basic workflow is as follows:

  1. upload the shapefile content to Mapbox Studio, and use the Studio interface to lay out the map. You have to have a Mapbox account to use Mapbox Studio (creating and designing maps using Mapbox Studio is free up to certain file size limitations). To learn how to use Mapbox Studio, you can refer to the manuals and tutorials made available by Mapbox here or other resources on the web.

  2. download the style.json from Mapbox Studio via the Mapbox Studio styles interface here

  3. copy both the shapefiles and style.json into the respective directories on Terrastories. Do not rename shapefiles or feature names in Mapbox Studio throughout this process -- the naming conventions must be consistent (aside from the additional -###### hash added by Mapbox Studio; more on that later).

Note: the user must provide their own shapefile content. It is not possible to use any of the standard OpenStreetMap (OSM) content used in the standard styles made available by Mapbox, unless the user first downloads that OSM content and converts it to shapefile first.

Step 2: adding new or updating shapefiles to Terrastories

To add new shapefiles or update existing shapefiles, there are two steps:

  1. Include the new files in your shapefile directory (\tilebuilder\shapefiles])

  2. You will need to re-run the tilebuilder, following the instructions here: https://github.com/rubyforgood/terrastories/blob/master/tilebuilder/README.md

Step 3: adding or updating style to the Map

To add or update the map style,

  1. download the style.json from Mapbox Studio via the Mapbox Studio styles interface here

  2. at this point, we have to edit the style.json a little. When you upload shapefiles to Mapbox Studio, it actually adds on an additional six alphanumeric characters preceded by a dash (-), which is called "hash." For example, a shapefile called "South_America" might be called "South_America-a2027z" in Mapbox Studio. And then in style.json file, all of the names for this layer will have "–a2027z" added to it. This is a problem because there is a discrepancy between the names of the shapefile you added in Step 2, which does no include "-a2027z." So, you have to go into the json and look for "source-layer": "South_America-a2027z", and take out the "-a2027z", and do the same for each layer.

In the future, we will create an automatic script that will take care of this process.

  1. copy the style into your styles directory (tileserver\data\styles])

  2. make sure that config.json in \tileserver\data\ is pointing to the right style file.

Importing data into Terrastories

In the Terrastories back end, it is possible to import data in bulk using a CSV importer.

The data should be imported in the following order: Places, Speakers, and then Stories.

To prepare CSVs for importing, use the following workflow to ensure that character diacritics are properly imported:

-If the file is already an .xlsx, go to Google Sheets and File->Import from the menu. Then import the file. -Otherwise create the file directly in Google Sheets. Make sure the file has a row for headers. -Go to File -> Download As-> Comma Separated Values, and save the file to your machine. -This CSV should be properly encoded as UTF-8. It's best to verify this with Notepad++ instead of Excel if you are on a Windows machine.

Adding languages to Terrastories

Terrastories uses internationalization to translate the application's core text, like the welcome page, sidebar, and administrative back end content. We have made it easy to add new languages to Terrastories without needing to touch any of the code.

To add a language to Terrastories, navigate to the rails/config/locales/ directory. Within this directory, each language has it's own subdirectory, like en (English) or pt (Portuguese). Currently, there are three files in each (using Portuguese as an example):

  1. pt.yml
  2. devise.pt.yml
  3. administrate.pt.yml

pt.yml contains the custom text used in the Terrastories application. devise.pt.yml and administrative.pt.yml are used by the administrative back end.

To set up a new language, create a new subdirectory in the locales folder. Let's assume you want to set up Papiamentu. Create a subdirectory called pap and copy over en.yml from the en folder. Rename it to pap.yml, change line 32 to pap, and translate each line of text in what follows.

For the devise and administrate files, there might be available translations already available online for common Western languages. If so, you can download these and place them in the directory, and make sure that the language code is consistent (for languages like Spanish and Portuguese, the language code might sometimes have a country-specific suffix like pt-BR). If translations are not available, do the same thing with these two files as translating en.yml.

If you want to change the default language for Terrastories, set the language on line 21 in rails/config/application.rb. To set it to Papiamentu, change this line to config.i18n.default_locale = :pap

Once you are done, the language should be available the next time you start Terrastories.

You can’t perform that action at this time.
