Prerequisites

Linux

The dependencies of this project can be installed with your favourite package manager, for example in Ubuntu they can be installed with this one-liner:

sudo apt-get install git curl docker docker-compose --yes

For extended information on installing Docker in Linux, visit https://docs.docker.com/engine/install/#server

macOS

Commercial use of Docker Desktop in macOS requires a licence, please raise a ticket with support to obtain one.

• curl is available by default in macOS
• git is available as a stub in /usr/bin, executing this will generate a system prompt to install Xcode. This is probably the easiest (and longest) way to get git installed. Alternate installation instructions can be found at https://git-scm.com/download/mac.
• docker and docker-compose are provided by Docker Desktop in macOS, visit https://docs.docker.com/desktop/mac/install/ for installation instructions.

Initial Setup

Steps in order to setup local environment

• Run the script ./git-pull-all-apps
• Run docker-compose up -d --build
• While the containers are running run docker-compose exec erm bundle exec rake db:setup db:migrate db:seed in order to create the db and add db seeds in the ERM DB
• While the containers are running run docker-compose exec esscentials bundle exec rake db:setup db:migrate db:seed in order to create the db and add db seeds in the esscentials DB

Tests

You can run tests by running:

• docker-compose exec erm bundle exec rspec for ERM
• docker-compose exec esscentials bundle exec rspec for esscentials

docker-compose restart	Restarts running containers
docker-compose ps	Shows status and network configurations of all running containers
docker-compose exec container_name command	Executes command within running container container_name
docker-compose run container_name command	Creates a temporary container from container_name and executes command within it
docker system prune --volumes	*** WARNING! *** Removes all stopped containers, unused networks, unused volumes, dangling images and dangling build cache
docker stats	Provides real-time system resource usage for all running containers

Docker potential issues

In docker we can set the disk space we want to reserve. If we do a lot of builds there is a chance to use most of this space. What we have to do:

• docker system df -v Check whether you have any unnecessary containers and images. If your client and daemon API are running version 1.25 or later (use the docker version command on the client to check your client and daemon API versions), you can see the detailed space usage information.
• docker system prune If there are lots of redundant objects run it to delete them.
