Use of uwazi-docker for development of Uwazi

The README.md have short explanation about how to use uwazi-docker fully dockered. This document aims to explain extra information for who is who is updating the code of Uwazi software and using this uwazi-docker only for it's dependencies.

Initial configuration

Note: will not be explained how to install Elastic Search and MongoDB databases since you can use both from uwazi-docker.

Install docker

Instructions about how to install docker are explained on requirements.

Install Uwazi requeriments

Important note: this topic in special is not granteed to be updated with lastest versions of Uwazi, so it's recommended to check at maintainer repository at https://github.com/huridocs/uwazi. Pull requests are welcome.

NodeJS

NVM Package manager

Is possible to install a specific version of a software on your system. But is a good idea use a package manager.

See how to install NVM at https://github.com/creationix/nvm#installation.

Yarn

See Yarn installation at https://yarnpkg.com/lang/en/docs/install/.

MongoDB Client

This step is not necessary if use install instructions at README.md#install

Some steps may need that you install the mongo client to be able to import the import data from commands mongo and mongorestore. See Mongo installation steps at https://docs.mongodb.com/manual/installation/.

Working with MongoDB and Elastic Search (containised on uwazi-docker)

Important: these require be executed on same directory of uwazi-docker. They will not work on uwazi directory. A good idea is have at least two different tabs.

# To run and see messages
docker-compose up elasticsearch mongo

# To run on background use -d param
docker-compose up -d elasticsearch mongo

# Stop all containers from uwazi-docker after they where not more need and
# avoid they stay running even after you reboot your operational system
docker-compose down

The following step is optional if you want to populate the databases not using uwazi-docker.

docker-compose run -e IS_FIRST_RUN=true --rm uwazi

Create your own repository

If you already does not have, join on GitHub with a free account. Then go to https://github.com/huridocs/uwazi and click fork.

fork-uwazi

You now have a forked version at https://github.com/YOUR-USERNAME/uwazi. A few steps more and you can create pull requests and contribute.

    • This link is great for who is new to git and GitHub and is not using linux. This guide assume use of command line interface
  • Interactive Git Tutorial: https://try.github.io
    • This is a good tutorial for who uses command like to work with git.

Working with Uwazi - your local fork

Important: some commands will only work on uwazi (not the docker-uwazi) folder

For complete instructions about how to run Uwazi for development, see the oficial guide at https://github.com/huridocs/uwazi#development. This document is a quick start.

# Clone your forked repository to a local folder
git clone [email protected]:YOUR-USERNAME/uwazi.git
cd uwazi

# Install node modules used by Uwazi.
yarn install

# Initialize databases (Mongo and Elastic Search) with Uwazi default blank values
# WARNING: if you already is using Uwazi and have Mongo and Elastic Search with
#          test or real data, this can potentially reset to initial state
#          depending of your environment variables like DATABASE_NAME and
#          ELASTICSEARCH_URL.
yarn blank-state

Now, each time you want to run, execute

yarn hot

If everything goes ok, you will see something similar to this:

yarn hot

Uwazi welcome screen by default will show at http://localhost:3000/

uwazi welcome screen

Extra tips

docker ps - See what is running

docker ps is a command to show what is running on docker. A comon problem to make a containers not run is the ports already used by a installed version of Mongo or Elastic Search on your machine or when a same container is lauched more than one time.

One example of output.

$ docker ps
CONTAINER ID        IMAGE                                                 COMMAND                  CREATED             STATUS              PORTS                              NAMES
22d753159257        docker.elastic.co/elasticsearch/elasticsearch:5.5.3   "elasticsearch -Expa…"   5 days ago          Up 3 minutes        0.0.0.0:9200->9200/tcp, 9300/tcp   uwazidocker_elasticsearch_1
752a0a2ab505        mongo:3.4                                             "docker-entrypoint.s…"   5 days ago          Up 3 minutes        0.0.0.0:27017->27017/tcp           uwazidocker_mongo_1

Protip: 0.0.0.0:9200->9200/tcp means that a container named uwazidocker_elasticsearch_1 is redirecting its internal port 9200 to your local development machine. 9300/tcp means the same container have the port 9300 open but its only acessible inside a docker network.

Debug Mongo and Elastic Search

# See log messages of Mongo and Elastic Search
docker-compose logs -f mongo elasticsearch

# Want some GUI to see what is happening on MongoDB? Use nosqlclient
docker-compose up -d mongo-gui-mongoclient

# Want some GUI to see what is happening on Elastic Search? Try Dejavu
docker-compose up -d elasticsearch-gui-dejavu

Configure ports of Mongo and Elastic Search

At this point, you have to edit the file docker-compose.yml and edit the hardcored values.

Protip: the most common error of using uwazi-docker with Uwazi a port is already used by another container or the installed Mongo / Elastic Search on your machine.
