PIH / pih-emr-invoke

A PyInvoke program that facilitates working with the PIH EMR

PIH OpenMRS Runner

This is a PyInvoke program that facilitates working with OpenMRS. It helps with setup, running, and git management of multiple repositories.

Please see the "Setup" section appropriate to your situation, whether you need to set up PIH EMR or you just want to use this with an existing setup.

This uses Python 2.7. Apologies. PRs welcome.

What does it do?

Once everything is set up, you can view the list of commands with

inv -l

There are a few different families of commands:

• Git commands such as inv git-status (I alias this to igs—I use it a lot)
• MySQL commands such as inv enable-modules
• Maven commands such as inv run (try invoke run --help)
• inv setenv, which changes which .env.* file is active (by virtue of being symlinked to .env)

Setup with existing OpenMRS development environment

These are the instructions for people who already have modules checked out and servers set up. If you're new to OpenMRS / PIH-EMR, please see the instructions below under "First-time setup."

This repository should be the parent directory of all of your OpenMRS project directories. Assuming the parent directory of your OpenMRS directories is not yet a git repository, cd to that directory and do

git init
git remote add origin [e-mail]:PIH/pih-emr-invoke.git
git pull origin master
sudo pip install -r requirements.txt

If you prefer, rather than doing sudo pip to install to your global Python environment, you could create a virtualenv for this. But as of this writing it's just PyInvoke and python-dotenv, which you're liable to want to use in every project for the rest of your life.

At this point we should create an .env.* file, which will define an OpenMRS working environment. Please see "The .env file" below to finish setup. Once done, you should be able to run invoke (or inv for short) commands.

First-time setup of OpenMRS on Ubuntu

I suggest installing Docker and using a dockerized MySQL (don't worry, the OpenMRS SDK will manage it all for you). Otherwise, you will need to install MySQL 5.6 (no other version will do).

sudo add-apt-repository 'deb http://archive.ubuntu.com/ubuntu trusty universe'
sudo apt-get update

# Install Git, Java, Maven, and PyInvoke
sudo apt install -y \
    build-essential \
    git \
    maven \
    openjdk-8-jdk \
    openjdk-8-jre \
    python-dev \
    python-invoke

# Set up OpenMRS SDK
mvn org.openmrs.maven.plugins:openmrs-sdk-maven-plugin:setup-sdk

# Set up PIH EMR Invoke
git clone [e-mail]:pih/pih-emr-invoke.git pihemr
cd pihemr/
git clone https://github.com/PIH/mirebalais-puppet.git

At this point we should create an .env.* file, which will define an OpenMRS working environment. Please see "The .env file" below, then come back here.

...

Okay, you have a .env file? Let's continue then.

inv setup

The only tricky question is which MySQL to use. If you're using docker, always pick (2), even if you already have a docker container.

inv run -sk

Navigate to http://localhost:8080/openmrs (or whatever port, if you used a different port). It will do some initial setup. In the end, the logs will show a bunch of errors, but the UI will show that the instance has been set up. You should cancel the current run (Ctrl-C in the terminal window).

inv configure

And check that the output looks okay. If so,

inv run -sk

once again. Startup should take several minutes as it loads in all required metadata, etc, for the first time.

Future runs can be executed with inv run, which automatically does a git pull, maven deploy, and enables all modules before running.

The .env file

To set up the .env file, do cp .env.sample .env.mysite and then edit .env.mysite to have the correct values:

• SERVER_NAME is the OpenMRS SDK serverId. Write something lowercase with dashes, like foo-bar. The corresponding MySQL database will be openmrs_foo_bar.
• CONFIG_REPO should be the path to the configuration repository for the server.
• OTHER_REPOS should be a comma-separated list of any repositories that are neither the CONFIG_REPO nor are watched modules, but which you'd like included in the git commands for this server. If your config repository depends on another config repository, this is a good place to put that.
• PIH_CONFIG is a comma-separated list of PIH Config files. See the files in the PIH Config Directory, and drop the pih-config- prefix and the .json suffix.
• MYSQL_INSTALLATION should be set to docker if you are using openmrs-sdk-mysql for MySQL. Otherwise omit it.

Finally, run inv setenv mysite, where mysite is the suffix of your .env file.
