How to use this image

To be fully operational, Linshare requires several components :

  • SMTP server
  • Database server (Postgres & MySQL drivers included)
  • ClamAV service (optional)


You can configure the above related settings through the following environment variables :

Environment variable Description
SMTP_HOST smtp host
SMTP_PORT smtp port
SMTP_USER smtp user
SMTP_PASS smtp password
POSTGRES_HOST postgres host
POSTGRES_PORT postgres port
POSTGRES_USER postgres user
POSTGRES_PASS postgres password
POSTGRES_DATABASE postgres database with default value "linshare"
MONGODB_HOST mongodb host
MONGODB_PORT mongodb port
MONGODB_USER mongodb user
MONGODB_PASS mongodb password
CLAMAV_HOST clamav host
CLAMAV_PORT clamav port
JAVA_OPTS java env variables
REPLICA_SET (optional) replica-set for "linshare" database (if not set MONGODB_HOST and MONGODB_PORT will be used)
REPLICA_SET_BIGFILES (optional) replica-set for "linshare-files" database (if not set MONGODB_HOST and MONGODB_PORT will be used)
REPLICA_SET_SMALLFILES (optional) replica-set for "linshare-bigfiles" database (if not set MONGODB_HOST and MONGODB_PORT will be used)


We add three mongodb environment variables in orther to specify the mongodb replica-set for each database.

Each environment variable must be set like this: "ip-adress-of-first-mongodb:mongodb-port,ip-adress-of-second-mongodb:mongodb-port,...".

For exemple if we had a replica-set of three mongodb replication for the "linshare-bigfiles" database we can add:
