Installation and usage

Installation is done in 3 steps: downloading source, installing dependencies and compiling it.

With Docker

Docker setup is recommended because it's easy, straightforward and Docker makes sure Usva cannot elevate it's privileges to the host system if an unknown vulnerability is exploited!

% git clone https://github.com/romeq/usva && cd usva
% cp config-example.toml config.toml
% $EDITOR config.toml
% make run-docker

Notes for config.toml when used with Docker

• IMPORTANT database.host must be equal to"db", which is the database's container name in docker-compose.yml
• server.address has to be 0.0.0.0 so that the server can be accessed from outside
• if SVPORT environment variable is set, server.port has to be equal to it
• database.port has to be 5432 or same as DB_PORT
• database.user has to be same as DB_USERNAME
• database.password has to be same as DB_PASSWORD
• database.database has to be same as DB_NAME

Without Docker

git clone https://github.com/romeq/usva && cd usva

# setup database user
# this step expects that you use "postgres" as the administrator user, if your system diverges from that just specify your system's one
export DB_HOST="127.0.0.1"
export DB_PORT=5432
export DB_OWNER=usva
createuser $DB_OWNER -PU postgres

# create database
DB_USERNAME=postgres \
	DB_PASSWORD=postgres \
	DB_OWNER=$DB_OWNER \
	make db-create

# configure server
cp config-example.toml config.toml
$EDITOR config.toml

# replace "dbownerpassword" with password you provided earlier on the createuser part
DB_USERNAME=$DB_OWNER \
	DB_PASSWORD=dbownerpassword \
	make migrateup setup build run

Server configuration

Note for Docker users

Docker image uses config.toml for the server's configuration. By default this file is shared between the host and the container for easy reconfiguration.

Configuration options

Full configuration can be found in config-example.toml, and we suggest for you to use a modified copy of that file as server's configuration.
