# What Is DICE Project?

DICE (Developing Innovation and Creativity in Education) is an international project co-funded by the Erasmus+ Programme of the European Union.

Its main goals are related to fostering innovation and creativity in education.

This project attempts to be a leading initiative that supports educational community to make progress in the field of innovation and creativity through effective, authentic, practical, sustainable actions.
This project has been funded with support from the European Commission.
For more information, see [http://www.diceproject.eu/][b].

**IT4Innovations participates in DICE. DICE uses the iRods software**

The integrated Rule-Oriented Data System (iRODS) is an open source data management software used by research organizations and government agencies worldwide. iRODS is released as a production-level distribution aimed at deployment in mission critical environments. It virtualizes data storage resources, so users can take control of their data, regardless of where and on what device the data is stored. As data volumes grow and data services become more complex, iRODS is serving an increasingly important role in data management, see [https://irods.org/][c].

## How to Put Your Data to Our Server

**Prerequisities:**

We have to be sure about your identity, this will be done throught this steps:

- at the first, fill this request for eudat [https://www.eudat.eu/contact-support-request?Service=B2SAFE][h]
- sign to MyAccessId [https://ds.myaccessid.org/][g] , after that, please create account at B2Access [https://b2access.eudat.eu/][d]
- after successfull login to B2Access, please sign in to our AAI at : [https://aai.it4i.cz/realms/IT4i_AAI/account/#/][f] throught your B2Access account. You can set new password. this new password will work for cyberduck and icommands.
- finally, contact our support@it4i.cz by crypted mail, we will create account at our iRods server and send you crypted mail.

### ***IT4I User (You Have IT4I Account With Access to Cluster Already)***

- iRODS clients are provided as a module on our ***Karolina*** cluster ( Barbora is in progress )
- module irodsfs contains config file for irodsfs nad for icommands too
- PAM passwords is password, you set in aai.it4i.cz

***How to mount your collection***

```console
ssh some_user@karolina.it4i.cz
ml irodsfs
```
- config files for irodsfs and icommands will be loaded 
- now you can choose between Fuse client or iCommands

***Fuse***

```console
$ ml irodsfs

The following have been reloaded with a version change:
  1) iRODS/0.7.3 => iRODS/0.7.6

iRODS configuration file has been created at /home/some_user/.config/iRODS/config.yml.

To mount your iRODS repository at ~/IRODS, run
        irodsfs -config ~/.config/iRODS/config.yml ~/IRODS

To unmount it, run
        fusermount -u ~/IRODS

$ irodsfs -config ~/.config/iRODS/config.yml ~/IRODS

time="2022-08-01 12:44:27.555090" level=info msg="Successfully started background process" function=parentRun package=main
```

you can work with fuse as an ordinary directory  ( ls, cd, cp, mv etc )

***iCommands***  

```console
ml irodsfs
iinit
Enter your current PAM password:
```
- put you password you set in keycloak

```console
ils
/IT4I/home/some_user:
  test.1
  test.2
  test.3
  test.4
```

- upload `iput` , download `iget`
- for more help, type `ihelp`

### ***Users Without IT4I Account (No Access to Cluster)***

- we suppose, you will upload your data from your local pc/vm

#### You Need a Client to Connect to iRods Server

- There are many iRods clients, but we recommend theese:
- Cyberduck - for windows / mac, GUI . Password from aai.it4i.cz (keycloak) works
- Fuse (irodsfs lite) - for linux, cli
- iCommands - for linux, cli . Password from aai.it4i.cz (keycloak) works

#### Cyberduck

- download at [https://cyberduck.io/download/][i]
- download connection profile for IT4I irods server [irods.cyberduckprofile][1]
- left doubleclick at this profile file opens connection

![](img/irods-cyberduck.jpg)

#### Irodsfs Lite

- work with your irods collection like ordinary directory
- this is linux client only, basic knowledge of commandline is neccessary
- PAM passwords is password, you set in aai.it4i.cz

```console
cd ~
wget https://docs.it4i.cz/irods1.it4i.cz.crt [k]
wget https://github.com/cyverse/irodsfs/releases/download/v0.7.6/irodsfs_amd64_linux_v0.7.6.tar
tar -xvf ~/irodsfs_amd64_linux_v0.7.6.tar
mkdir ~/IRODS
```

settings:

```console
vim ~/config.yml
```

```console
host: irods1.it4i.cz
port: 1247
proxy_user: some_user
client_user: some_user
zone: IT4I

authscheme: "pam"
ssl_ca_cert_file: "~/irods1.it4i.cz.crt"
ssl_encryption_key_size: 32
ssl_encryption_algorithm: "AES-256-CBC"
ssl_encryption_salt_size: 8
ssl_encryption_hash_rounds: 16

path_mappings:
  - irods_path: /IT4I/home/some_user
    mapping_path: /
    resource_type: dir
```

***How to start - mount your collection:***

```console
./irodsfs -config ~/config.yml ~/IRODS
time="2022-07-29 09:51:11.720831" level=info msg="Logging to /tmp/irodsfs_cbhp2rucso0ef0s7dtl0.log" function=processArguments package=main
Password:

```

***How to put your data to iRODS***

```console
cp test1G.txt ~/IRODS
```

It works as ordinary filesystem

```console
ls -la ~/IRODS
total 0
-rwx------ 1 some_user some_user 1073741824 Nov  4  2021 test1G.txt
```

***How to stop - unmout your collection:***

```console
fusermount -u ~/IRODS
```

#### iCommands

- this is linux client only, basic knowledge of commandline is neccessary
- manual is for centos7
- for ubuntu20 - there is [http://docs.snic.se/wiki/IRODS_iCommands_installation_on_Ubuntu_20.04#Authenticate_and_test_iRODS_iCommands_client][j]
- ***please do NOT install icommands 4.3.0, it is NOT working with PAM***

```console
sudo rpm --import https://packages.irods.org/irods-signing-key.asc
sudo wget -qO - https://packages.irods.org/renci-irods.yum.repo | sudo tee /etc/yum.repos.d/renci-irods.yum.repo
sudo yum install epel-release -y
sudo yum install python-psutil python-jsonschema
sudo yum install irods-icommands-4.2.7-1.x86_64 
mkdir ~/.irods/
cd ~ && wget https://docs.it4i.cz/irods1.it4i.cz.crt [k]
```

Copy&paste + edit irods_user_name

```console
$ vim ~/.irods/irods_environment.json
{
    "irods_host": "irods1.it4i.cz",
    "irods_port": 1247,
    "irods_user_name": "some_user",
    "irods_zone_name": "IT4I",
    "irods_authentication_scheme": "PAM",

    "irods_ssl_ca_certificate_file": "~/irods1.it4i.cz.crt",
    "irods_encryption_algorithm": "AES-256-CBC",
    "irods_encryption_key_size": 32,
    "irods_encryption_num_hash_rounds": 16,
    "irods_encryption_salt_size": 8
}
```

```console
$ pwd
/some_user/.irods

$ ls -la
total 16
drwx------. 2 some_user some_user 136 Sep 29 08:53 .
dr-xr-x---. 6 some_user some_user 206 Sep 29 08:53 ..
-rw-r--r--. 1 some_user some_user 253 Sep 29 08:14 irods_environment.json
```

**How to Start:**

**step 1:**

```console
$ iinit
Enter your current PAM password:

$ ils
/IT4I/home/some_user:
  file.jpg
```

***how to put your data to IRODS***

```console
$ iput cesnet.crt
```

```console
$ ils
/IT4I/home/some_user:
  cesnet.crt
```

***How to download data***

```console
$ iget cesnet.crt
