irods_demo

This repository provides a docker-compose project designed to easily stand up a DEMONSTRATION of the iRODS server and a few of its clients. It is intended for education and exploration.

DO NOT USE IN PRODUCTION.

Requirements

• docker
• docker-compose

A minimal configuration will have:

• 2 CPUs
• 4 GB RAM
• 10 GB storage

Run

If you have not initialized submodules in this repo, run the following before attempting to start the Compose project:

$ git submodule update --init

git submodule update should be run any time the submodule is updated, so make sure to run it any time you pull or checkout different commits.

To run all services:

$ docker-compose up

To run an individual service (and all services on which it depends):

$ docker-compose up <service-name>

For example, this command will spawn containers for the following services:

1. irods-catalog
2. irods-catalog-provider
3. irods-client-rest-cpp
4. nginx-reverse-proxy
5. irods-client-zmt

$ docker-compose up irods_client_zmt

For more information about Compose CLI options, see Docker Compose documentation: https://docs.docker.com/engine/reference/commandline/compose

Notes for services

irods-client-zmt / Zone Management Tool / ZMT

The ZMT service assumes that containers are running on the same host as the browser. If this is not the case (launching irods_demo via ssh, etc.), the value of REACT_APP_REST_API_URL should be changed to an address which correctly maps to the nginx-reverse-proxy service and that is reachable by both the ZMT service and the host running the browser.

-            - REACT_APP_REST_API_URL=http://localhost/irods-rest/x.x.x
+            - REACT_APP_REST_API_URL=http://<public-hostname-or-ip>/irods-rest/x.x.x

irods-client-nfsrods / NFSRODS

Once the service is running, the NFS server needs to be accessed from a mountpoint. This can be done with the following command:

$ sudo mount -o sec=sys,port=2050 localhost:/ ./irods_client_nfsrods/nfs_mount

The hostname can also be the IP address of the container providing the service in the irods_demo_default Docker network if running from the same host. The mountpoint can exist on any other machine which can reach the host running the container providing the service because the port is being exposed, in which case the FQDN or IP address for the host machine can be used. For more information about mounting NFSRODS, see the README for the project: https://github.com/irods/irods_client_nfsrods#mounting

When you are ready to stop the service, it would be a good idea to unmount first. This can be done by running the following:

$ sudo umount ./irods_client_nfsrods/nfs_mount

The NFSRODS service maps the /etc/passwd file on the host machine to the /etc/passwd file in the container providing the service. The user(s) accessing the mountpoint will need to exist as iRODS users as well in order to be able to interact with the mountpoint. This can be done by running the following command on the host machine for each username which needs to be mapped:

$ docker exec irods_demo_irods-client-icommands_1 iadmin mkuser <username> rodsuser
