HydroShare is a website and hydrologic information system for sharing hydrologic data and models aimed at providing the cyberinfrastructure needed to enable innovation and collaboration in research to solve water problems. HydroShare is designed to advance hydrologic science by enabling the scientific community to more easily and freely share products resulting from their research, not just the scientific publication summarizing a study, but also the data and models used to create the scientific publication. With HydroShare users can: (1) share data and models with colleagues; (2) manage who has access to shared content; (3) share, access, visualize and manipulate a broad set of hydrologic data types and models; (4) use the web services API to program automated and client access; (5) publish data and models to meet the requirements of research project data management plans; (6) discover and access data and models published by others; and (7) use web apps to visualize, analyze, and run models on data in HydroShare.

Prerequisites

Supported OS (developer laptops): macOS 10.12+, Win10+ Pro, Ent, Edu, Acad Pro, Acad Ent, CentOS 7 and Ubuntu/Lubuntu 18+ LTS

We got some troubles with Lubuntu 16.04 LTS so probably Ubuntu 16.04 LTS also does not work

Familiarity with docker and git are required to work with HydroShare

Some VM skills such as network settings (Bridge/NAT/Host only) and file sharing are needed if you work with a virtual machine.

For Windows, this link is required to proceed - https://docs.google.com/document/d/1wIQEYq3OkWmzPTHeyGyjXLZWrinEXojJPBTJq7fczL8/edit#heading=h.mfmd8m9mxvsl

One-Time Install

Tables are provided (in Courier font) throughout this wiki for copy-paste of entire blocks.

1. Open a terminal (macOS, Linux) or command prompt (Windows) Navigate to where you will store the source code, for example /Users/yourname/repo/

Typically you will find it under this directory:

cd ~/repo

2. Get code

Note it should have a default branch set to the develop branch

git clone https://github.com/hydroshare/hydroshare.git

git checkout <branch>

To get current solr revision fixes:

  a. git pull

cd hydroshare

b. docker exec -u hydro-service -ti hydroshare python manage.py solr_update

It’s very important that please DO NOT change the directory name after cloned. Let it be “hydroshare” If you are running inside a virtual machine such as HydroDev Ubuntu 18.04 from here, you need to: Replace all FQDN_OR_IP on the file nginx/config-files/hydroshare-local-nginx.conf.template to be your VM IP address (totally four positions need to be replaced)

Add a new line into .gitignore file to make sure you will not commit your local setting to GitHub

/nginx/config-files/hydroshare-local-nginx.conf.template

If you are running Windows 10, please make sure no process is listening on port 80. This maybe a pain for Windows 10 user, we found a very useful link here. However, if you can't stop the process which is listening on port 80, you need to do these steps:

Change the nginx port by modify this file: local-dev.yml (change port setting from 80:80 to 8080:80 on nginx section)

Replace line 26 on the file nginx/config-files/hydroshare-local-nginx.conf.template from

if ($http_host != "FQDN_OR_IP") {

To

if ($http_host != "FQDN_OR_IP:8080") {

Replace line 35 on the file nginx/config-files/hydroshare-local-nginx.conf.template from

rewrite ^ http://FQDN_OR_IP$request_uri permanent;

To

rewrite ^ http://FQDN_OR_IP:8080$request_uri permanent;

Add new two lines into .gitignore file to make sure you will not commit your local setting to GitHub

local-dev.yml

/nginx/config-files/hydroshare-local-nginx.conf.template

3. Log into Docker via application and command line. Command line:

   docker login

   You will be asked to enter your username and password

4. Launch the stack

    ./local-dev-first-start-only.sh
   

Following the screen instruction to continue.

Run the following command on completion to launch Hydroshare:

docker-compose -f local-dev.yml up 

5. Sanity Checks

   Some WARNINGs are normal.

   HydroShare is available in your browser at http://localhost or http://localhost:8080 in case you are running inside a VM

   The default admin page is http://localhost/admin

   The default admin account is admin:default

   Swagger API docs http://localhost/hsapi/

6. Start & Stop & Log

To start HydroShare, only need to open a windows shell, change to HydroShare code directory then run

docker-compose -f local-dev.yml (up | down) [-d] [--build]

Note bracketed -d for daemon is optional and you don’t paste in the brackets

Use -d option in case you want to type new command on this windows or don’t want to see real-time output log.

Use --build option in case docker keeps image in cache and does not update correctly while modifying the Dockerfile and working with PyCharm

CREATE NEW ACCOUNT - This is the same as it's always been in HydroShare. Ask a teammate or hack at it. Basically open a hydroshare console window then use the UI to sign up for a new account and watch the hydroshare container console (docker logs hydroshare) for a verification link and paste that into your browser and save the new account in the UI.

If your develop machine is slow, the defaultworker container may not work properly because it won’t see iRODS containers alive after timeout. Please wait seconds, open new terminal window then restart this container by the command: docker restart defaultworker, or just only start the whole HydroShare system by this command: ./slow-start.sh (no need to run docker-compose -f local-dev.yml up) but by this way, you will not have native log window.

To stop HydroShare, only need to close the running windows or open a new windows then run

docker-compose -f local-dev.yml down

All data is persisted for the next start.

To see the logs in case you start with -d option, open a windows then run

docker-compose -f local-dev.yml logs

Or

docker logs <container name>

Branching When you activate a new branch, just bring the stack down and up again. Sometimes you can get away with a warm restart of the stack or even relying on the Django debug mode (doing nothing but waiting).

For all intents and purposes, Hydroshare is a large Python/Django application with some extra features and technologies added on:

• SOLR for searching
• Redis for caching
• RabbitMQ for concurrency and serialization
• iRODS for a federated file system
• PostgreSQL for the database backend

The hsctl script is your primary tool in interacting with and running tasks against your Hydroshare install. It has the syntax ./hsccl [command] where [command] is one of:

• loaddb: Deletes existing database and reloads the database specified in the hydroshare-config.yaml file.
• managepy [args]: Executes a python manage.py [args] call on the running hydroshare container.
• maint_off: Removes the maintenance page from view (only if NGINX is being used).
• maint_on: Displays the maintenance page in the browser (only if NGINX is being used).
• rebuild: Stops, removes and deletes only the hydroshare docker containers and images while retaining the database contents on the subsequent build as defined in the hydroshare-config.yaml file
• rebuild --db: Fully stops, removes and deletes any prior hydroshare docker containers, images and database contents prior to installing a clean copy of the hydroshare codebase as defined in the hydroshare-config.yaml file.
• rebuild_index: Rebuilds the solr/haystack index in a non-interactive way.
• restart: Restarts the django server only (and nginx if applicable).
• start: Starts all containers as defined in the docker-compose.yml file (and nginx if applicable).
• stop: Stops all containers as defined in the docker-compose.yml file.
• update_index: Updates the solr/haystack index in a non-interactive way.

Tests are run via normal Django tools and conventions. However, you should use the hsctl script mentioned abouve with the managepy command. For example: ./hsctl managepy test hs_core.tests.api.rest.test_resmap --keepdb.

There are currently over 600 tests in the system, so it is highly recommended that you run the test suites separately from one another.

You can debug via PyCharm by following the instructions here.

Local iRODS is not required for development unless you are specifically working on the iRODS integration. However,if you want to work with iRODS or you simply want to learn about it, you can enable it locally.

To enable HTTPS locally:

1. edit config/hydroshare-config.template and change the two values under ### Deployment Options ### to true like so:

### Deployment Options ###
USE_NGINX: true
USE_SSL: true

restart local Hydroshare

docker-compose -f local-dev.yml down
docker-compose -f local-dev.yml up -d
