ISG on CentOS 7

This section contains everything you need to know about installing and managing the iconik Storage Gateway (ISG)

1. Download and install the Iconik Storage Gateway

Set up the iconik Yum repository, and install the Iconik Storage Gateway RPM

cd /etc/yum.repos.d
sudo wget
sudo yum install iconik_storage_gateway

It will be installed in /opt/cantemo/iconik_storage_gateway where you will also find the config file called config.ini

2. Edit config.ini

Edit config.ini to look like this (See Setting up how to get the correct values)


app-id = 22f34c6e-268e-11e7-ac53-6c4008b85488
storage-id = 15fa3f68-7693-11e7-bf0c-02420a021013
iconik-url =
auth-token = eyJhbGciOiJIUzI1NiIsImlhdCI6MTUwMTU3NjAyNCwiZXhwIjoxNTAxNjE5MjI0fQ.eyJpZCI6IjMzMjFkMjIyLTc2OTMtMTFlNy1hN2EyLTAyNDIwYTAyMTAxYSJ9.sgag4OQb19J9qT1IAdKZYAqbpIoai7oW60Mahye7o8s
sleep-time = 10
max-transcoding-jobs = 1
file-upload-parallel-uploads-num = 4
file-download-parallel-downloads-num = 4
log-filename = /var/log/cantemo/iconik_storage_gateway/default.log

3. Start the service

Iconik Storage Gateway will add a system user called cantemo that will be used to run systemd service. The cantemo user must have permissions to read/write the storage mount point folder and it contents. You can add the cantemo user to a group to manage permissions on group level instead.

After installation you can start service with:

sudo systemctl enable iconik_storage_gateway
sudo systemctl start iconik_storage_gateway

To check status of the service use:

sudo systemctl status iconik_storage_gateway

For following the log file, you can use the following command:

sudo tail -f /var/log/cantemo/iconik_storage_gateway/default.log

You can run also run the systemd service from your custom user by providing an override (sudo systemctl edit iconik_storage_gateway.service) passing your own config and log files that are accessible for your custom user. Log file location can also be set in config.


ExecStart=/usr/bin/iconik_storage_gateway --config=/home/john/iconik_storage_gateway/config.ini --log-filename=/home/john/iconik_storage_gateway/default.log

You will need to give your new user permissions to the database file and the log directory as well (If you didn't change the logs)

sudo chown -R john:john /var/cantemo/iconik_storage_gateway/
sudo chown -R john:john /var/log/cantemo/iconik_storage_gateway/

After adding your custom user you need to restart service.

sudo systemctl daemon-reload
sudo systemctl restart iconik_storage_gateway

Local transcoding (Optional)

For local transcoding to work you will have to install ffmpeg, poppler and ImageMagick. Make sure they are in the path for the user running the service.

Below is one way of doing so, but please do not use on a production setup without checking compatibility with other software:

sudo yum install epel-release -y
sudo yum update -y
sudo rpm -Uvh
sudo yum install ffmpeg ffmpeg-devel ImageMagick poppler-utils ghostscript ufraw -y

Alternatively, you can download a static build of ffmpeg which doesn't require any additional libraries. This is available from

To get frame accurate playback in other browsers than Safari you also need mp4mux from Bento4.

You can download binaries from but the latest version does not work properly on CentOS 7. Please use the version available at instead.

Unpack the correct package, and copy the mp4mux binary to /usr/local/bin

To write xmp metadata which can be used in our adobe integration to the proxy files you need Exiftool

sudo yum install perl-Image-ExifTool

Update the storage settings in Iconik to say Local keyframes and Local proxy and restart the service.
