Dockerized iRODS

This repository contains the necessary files to build an iRODS Docker image based on Ubuntu 18.04. The code is based on hurngchunlee/docker-irods.

The image contains features specific to our SODAR system, but using them is optional and the image also works as a generic iRODS server.

Building

$ cd docker
$ docker build .

Data Persistency

Each container exposes volumes for data persistency. The list of volumes are provided in the table below:

path in container usage
/etc/irods resource server configuration
/var/lib/irods/iRODS/server/log resource server log

For iRODS services, the setup script (/var/lib/irods/scripts/setup_irods.py) is only executed when the file /etc/irods/.provisioned is not present. The file /etc/irods/.provisioned is created when the setup script is executed successfully.

Commands

The following commands are available. If you specify anything else then the startup script will exec this command (e.g., bash).

  • irods-start (default) -- Start iRODS server

Environment Variables

There are several environment variables can be set for setting up iRODS. The variables are feeded into the iRODS setup script (/var/lib/irods/scripts/setup_irods.py) for the first startup. They are summarised below. iRODS can be run in either "provider" mode, which installs an iCAT catalogue server, or "consumer" mode which only installs a resource server to be used with a remote iRODS provider. The "Role" column shows for which role(s) each variable is used.

IRODS_CATALOG_PROVIDER_HOST consumer

SSSD Support

In addition to the base image, we provide the images ${VERSION}-sssd (e.g., 4.2.11-1-sssd) which have SSSD installed. You will have to share /var/lib/sss between the SSSD container and iRODS so both containers can communicate.

In our installations, we run bihealth/sssd-docker in a second container.

Troubleshooting

A previous version of this image was built on CentOS7 instead of Ubuntu. If updating or redeploying an existing installation, you may encounter the following error connecting to the iRODS database: [unixODBC][Driver Manager]Data source name not found, and no default driver specified

To fix this, first edit the file /etc/irods/server_config.json. Find the variable db_odbc_driver and change its value from PostgreSQL to PostgreSQL Unicode.

Next, do the same modification for the environment variable IRODS_ODBC_DRIVER. After restarting the image, iRODS should work normally.
