Running the image

docker run \
    -d \
    --name=healthchecks \
    -p 80:8000 \
    -e 'HC_HOST=0.0.0.0' \
    -e 'HC_PING_EMAIL_DOMAIN=example.com' \
    -e 'HC_SITE_ROOT=http://example.com' \
    -e 'HC_EMAIL_HOST=smtp.example.com' \
    -e 'HC_EMAIL_PORT=25' \
    -e 'HC_EMAIL_USE_TLS=True' \
    -e 'HC_EMAIL_HOST_USER=user@example.com' \
    -e 'HC_EMAIL_HOST_PASSWORD=YOUR_PASSWORD' \

When you don't want to use SQLite. The following environment variables can be used to configure the database connection:

DB_TYPE # Can be postgresql, mysql (defaults to sqlite3)
DB_HOST # the database host address
DB_PORT # the database host port
DB_NAME # the database name
DB_USER # the database user
DB_PASSWORD # the database user password
