Set up services

Generate an encryption key

from cryptography.fernet import Fernet
Fernet.generate_key().decode()

Create .env

MEGANNO_PROJECT_NAME=meganno
MEGANNO_PROJECT_DIR=./meganno_data
MEGANNO_SERVICE_PORT=5000
MEGANNO_AUTH_PORT=5001
MEGANNO_NEO4J_PASSWORD=meganno
MEGANNO_ADMIN_USERNAME=admin
MEGANNO_ADMIN_PASSWORD=
MEGANNO_ENCRYPTION_KEY=
MEGANNO_IMAGE=api-1.2.0
MEGANNO_AUTH_IMAGE=auth-1.0.0

Variable	Default	Description
MEGANNO_PROJECT_NAME	meganno	Name of the meganno project
MEGANNO_PROJECT_DIR	./meganno_data	Root directory for Neo4j database folders such as data/, logs/, and instance/
MEGANNO_SERVICE_PORT	5000	API service port
MEGANNO_AUTH_PORT	5001	Authentication service port
MEGANNO_AUTH_HOST		For multi-project set up (ignore otherwise)
MEGANNO_NEO4J_PASSWORD	meganno	Password for Neo4j database
MEGANNO_ADMIN_USERNAME	admin	Adminitrator username for default admin. account (only needed it for auth service)

Docker

Install Docker (on Linux)

for other system platforms, follow instructions on "Install Docker Engine" to install docker and docker compose.

sudo yum update -y
sudo yum install docker -y
sudo service docker start

Install Docker Compose plugin (on Linux)

sudo -i
mkdir -p ~/.docker/cli-plugins/
curl -SL https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
chmod +x ~/.docker/cli-plugins/docker-compose
exit

Start meganno-service backend

Both single-project.yaml and .env files should be under the same directory.

sudo docker compose -f single-project.yaml up -d

Multi-project auth set up

You can configure multiple projects to connect to the same backend auth server. With this set up, users do not have to recreate their accounts for individual projects under the same team.

# replace {MEGANNO_AUTH_PORT}, {MEGANNO_PROJECT_DIR}
# with default values or values in .env file
sudo docker run --env-file .env -p {MEGANNO_AUTH_PORT}:{MEGANNO_AUTH_PORT} -p 43259:43259 -v "$(pwd)/{MEGANNO_PROJECT_DIR}/instance:/instance" -v "$(pwd)/{MEGANNO_PROJECT_DIR}/logs/auth:/logs" -td megagonlabs/meganno-service:auth-1.0.0

sudo docker compose -f multi-project.yaml up -d

Testing

cd tests/
pip install -r requirements.txt
