Development environment

Using Docker

git clone git@gitlab.com:kazarma/kazarma.git
cd kazarma
git submodule update --init --recursive
docker compose run --rm synapse generate
docker compose run --rm kazarma mix do deps.get, ecto.setup
docker compose run --rm kazarma npm --prefix assets install
caddy start
docker compose up -d
docker compose exec pleroma pleroma/bin/pleroma_ctl frontend install pleroma-fe --ref stable

On Linux, use docker-hoster to make container domains accessible:

docker run -d \
    -v /var/run/docker.sock:/tmp/docker.sock \
    -v /etc/hosts:/tmp/hosts \
    --name docker-hoster \
    dvdarias/docker-hoster@sha256:2b0e0f8155446e55f965fa33691da828c1db50b24d5916d690b47439524291ba

(after rebooting, you will need to start it again using docker start docker-hoster)

This should run containers with those services:

• kazarma.kazarma.com -> Kazarma itself
• matrix.kazarma.com -> Matrix server
• kazarma.com -> serves .well-known routes that allow Matrix and Kazarma.ActivityPub to use simple kazarma.com domain (for users, etc)
• pleroma.com -> Pleroma, should be able to address Matrix users using kazarma.com domain
• element.com -> Element, will connect to Synapse, should then be able to address Pleroma users using pleroma.com domain

You can also start an IEx console:

docker compose run --rm kazarma iex -S mix

On macOS

On macOS, instead of docker-hoster you need to add the following domains to your /etc/hosts file:

# Kazarma development domains
127.0.0.1 kazarma.com
127.0.0.1 kazarma.kazarma.com
127.0.0.1 matrix.kazarma.com
127.0.0.1 pleroma.com
127.0.0.1 element.com

Then the docker-compose.yml file should (at least) expose the 80 port in the traefik container:

  traefik:
    image: traefik:v2.2.0
    ports:
      - 80:80
      - 443:443

Reset databases

docker compose rm -fs postgres_kazarma postgres_pleroma synapse
docker volume rm kazarma_postgres_pleroma_files kazarma_postgres_kazarma_files kazarma_synapse_files
docker compose run --rm synapse generate
docker compose run --rm kazarma mix ecto.setup

Without using Docker

git clone git@gitlab.com:kazarma/kazarma.git
cd kazarma
git submodule update --init --recursive
mix do deps.get, ecto.setup
iex -S mix phx.server

Run tests

mix test

Generate documentation

We use ditaa to generate diagrams and integrate them into HexDoc. To edit diagrams use asciiflow and paste the result in HTML files in the doc_diagrams folder.

rm doc_diagrams/*.png && ditaa doc_diagrams/*.html
mix docs
