# Setting up DSS item exports to PDF or images[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#setting-up-dss-item-exports-to-pdf-or-images "Permalink to this headline")

The Flow, Dashboards and Wiki articles can be exported to PDF or image (PNG, JPG) files in order to propagate information inside your organization more easily. The export feature must be setup prior to being usable.

## Prerequisites[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#prerequisites "Permalink to this headline")

* The export feature does not work on Centos 6 and AmazonLinux

* Internet access is required to install additional dependencies required by the export feature

* The account running DSS needs write access to the DSS installation directory at install time;

## Precautions[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#precautions "Permalink to this headline")

The export feature uses an embedded Chrome browser to perform the actual snapshotting. When you install the feature, an up-to-date Chrome browser is downloaded. We recommend that you regularly perform again the install procedure in order to fetch latest updates, which may be required since Chrome regularly releases security updates.

Security updates of the embedded Chrome browser are not the responsibility of Dataiku.

The embedded Chrome browser is in the `resources/graphics-export/node\_modules` folder of the DSS installation directory. In case of doubt, you can remove this folder, which will prevent the feature from working.

As of DSS 5.1, this will download and install puppeteer 1.10 and its associated headless chromium version (72.0).

## Install[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#install "Permalink to this headline")

* Go to the DSS data dir

* Stop DSS

>

>

> ```

> ./bin/dss stop

>

> ```

>

>

>

* Run the installation script

>

>

> ```

> ./bin/dssadmin install-graphics-export

>

> ```

>

>

>

* If prompted to, run the dependencies installation script as root

* Start DSS

>

>

> ```

> ./bin/dss start

>

> ```

Test the feature by going to a dashboard, in view mode, and clicking Actions > Export. Alternatively you can test the feature by going to the Flow of a project and clicking Flow Actions > Export to PDF/Image

If you get an error about sandbox mode, it means that the embedded Chrome browser could not start in the most secure “sandbox” mode

### Option 1: Enable user namespaces[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#option-1-enable-user-namespaces "Permalink to this headline")

The sandbox mode of Chrome runs using a feature of the Linux kernel known as user process namespaces. This feature is not always enabled, you may need to enable it.

Run the following command:

§ sysctl user.max_user_namespaces

If the result is 0, run the following command as root:

§ sysctl user.max_user_namespaces=1000

If the result was 0 in the previous step, you will also want to add this entry to your `/etc/sysctl.conf` file so that this setting is retained upon server reboot:

§ # edit your /etc/sysctl.conf file

§ sudo vi /etc/sysctl.conf

§ # add the following entry to the end of the file

§ user.max_user_namespaces=1000

Then retry exporting the Flow or dashboard

### Option 2: Disable sandbox[¶](https://doc.dataiku.com/dss/latest/installation/graphics-export.html#option-2-disable-sandbox "Permalink to this headline")

If you are not able to run the previous, or if it fails (which may be possible if you have a too old kernel), you can disable the additional sandbox protection. The sandbox is a “second level” of security to mitigate exploitation possibilities in case of a security bug in Chrome.

* Edit the `config/dip.properties` file

* Add the following line: `dku.exports.chrome.sandbox=false`

* Restart DSS
