# 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.
The 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:**

First, we need to verify your identity, this is done through the following steps:

1. Sign in with your organisation [B2ACCESS][d]; the page requests a valid personal certificate (e.g. GEANT).
  Accounts with "Low" level of assurance are not granted access to IT4I zone.

1. Confirm your certificate in the browser:

    ![](img/B2ACCESS_chrome_eng.jpg)

1. Confirm your certificate in the OS (Windows):

    ![](img/crypto_v2.jpg)

1. Sign to EUDAT/B2ACCESS:

    ![](img/eudat_v2.jpg)

1. After successfull login to B2Access:

    1. **For Non IT4I Users**

         Sign in to our [AAI][f] through your B2Access account.
         You have to set a new password for iRods access.

    1. **For IT4I Users**

         Sign in to our [AAI][f] through your B2Access account and link your B2ACCESS identity with your existing account.
         The IRODS password will be the same as your IT4I LDAP password (i.e. code.it4i.cz password).

## Access to iRods Collection From Karolina

Access to iRods Collection requires access to the Karolina cluster (i.e. [IT4I account][4]),
since iRODS clients are provided as a module on Karolina (Barbora is in progress).
The `irodsfs` module loads config file for irodsfs and icommands, too.

Note that you can change password to irods [aai.it4i.cz][m].

### Mounting Your Collection

```console
ssh some_user@karolina.it4i.cz
ml irodsfs
```

Now you can choose between the Fuse client or iCommands:

#### Fuse

```console
ssh some_user@karolina.it4i.cz
[some_use@login4.karolina ~]$ ml irodsfs

irodsfs configuration file has been created at /home/dvo0012/.irods/config.yml
iRODS environment file has been created at /home/dvo0012/.irods/irods_environment.json

to start irodsfs, run:          irodsfs -config ~/.irods/config.yml ~/IRODS
to start iCommands, run:        iinit

For more information, see https://docs.it4i.cz/dice/
```

To mount your iRODS collection to ~/IRODS, run

```console
[some_user@login4.karolina ~]$ irodsfs -config ~/.irods/config.yml ~/IRODS
time="2022-08-04 08:54:13.222836" level=info msg="Logging to /tmp/irodsfs_cblmq5ab1lsaj31vrv20.log" function=processArguments package=main
Password:
time="2022-08-04 08:54:18.698811" level=info msg="Found FUSE Device. Starting iRODS FUSE Lite." function=parentMain package=main
time="2022-08-04 08:54:18.699080" level=info msg="Running the process in the background mode" function=parentRun package=main
time="2022-08-04 08:54:18.699544" level=info msg="Process id = 27145" function=parentRun package=main
time="2022-08-04 08:54:18.699572" level=info msg="Sending configuration data" function=parentRun package=main
time="2022-08-04 08:54:18.699730" level=info msg="Successfully sent configuration data to background process" function=parentRun package=main
time="2022-08-04 08:54:18.922490" level=info msg="Successfully started background process" function=parentRun package=main
```

To unmount it, run

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

You can work with Fuse as an ordinary directory  (`ls`, `cd`, `cp`, `mv`, etc.).

#### iCommands

```console
ssh some_user@karolina.it4i.cz
[some_use@login4.karolina ~]$ ml irodsfs
irodsfs configuration file has been created at /home/dvo0012/.irods/config.yml.
      to start irods fs run: irodsfs -config ~/.irods/config.yml ~/IRODS

iCommands environment file has been created at /home/$USER/.irods/irods_environment.json.
      to start iCommands run: iinit

[some_user@login4.karolina ~]$ iinit
Enter your current PAM password:
```

```console
[some_use@login4.karolina ~]$ ils
/IT4I/home/some_user:
  test.1
  test.2
  test.3
  test.4
```

Use the command `iput` for upload, `iget` for download, or `ihelp` for help.

## Access to iRods Collection From Other Resource

!!! note
    This guide assumes you are uploading your data from your local PC/VM.

Use the password from [AAI][f].

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

There are many iRods clients, but we recommend the following:

- Cyberduck - Windows/Mac, GUI
- Fuse (irodsfs lite) - Linux, CLI
- iCommands - Linux, CLI.

For access, set PAM passwords at [AAI][f].

### Cyberduck

1. Download [Cyberduck][i].
2. Download [connection profile][1] for IT4I iRods server.
3. Left doubleclick this file to open connection.

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

### Fuse

!!!note "Linux client only"
    This is Linux client only, basic knowledge of command line is neccessary.

Fuse allows you to work with your iRods collection like an ordinary directory.

```console
cd ~
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 ~/.irods/ && cd "$_" && wget https://docs.it4i.cz/config.yml
wget https://pki.cesnet.cz/_media/certs/chain_geant_ov_rsa_ca_4_full.pem -P ~/.irods/
sed -i 's,~,'"$HOME"',g' ~/irods/irods_environment.json
```

Edit `~/.irods/config.yml` with username from [AAI][f].

#### Mounting Your Collection

```console
[some_user@local_pc ~]$ ./irodsfs -config ~/.irods/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:

time="2022-07-29 09:51:17.691988" level=info msg="Found FUSE Device. Starting iRODS FUSE Lite." function=parentMain package=main
time="2022-07-29 09:51:17.692683" level=info msg="Running the process in the background mode" function=parentRun package=main
time="2022-07-29 09:51:17.693381" level=info msg="Process id = 74772" function=parentRun package=main
time="2022-07-29 09:51:17.693421" level=info msg="Sending configuration data" function=parentRun package=main
time="2022-07-29 09:51:17.693772" level=info msg="Successfully sent configuration data to background process" function=parentRun package=main
time="2022-07-29 09:51:18.008166" level=info msg="Successfully started background process" function=parentRun package=main
```

#### Putting Your Data to iRODS

```console
[some_use@local_pc ~]$ cp test1G.txt ~/IRODS
```

It works as ordinary filesystem

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

#### Unmounting Your Collection

To stop/unmount your collection, use:

```console
[some_user@local_pc ~]$ fusermount -u ~/IRODS
```

### iCommands

-!!!note "Linux client only"
    This is Linux client only, basic knowledge of command line is neccessary.

We recommend Centos7, Ubuntu 20 is optional.

#### Steps for Ubuntu 20

```console
