Installing pretix Enterprise plugins

If you want to use a feature of pretix that is part of our commercial offering pretix Enterprise, you need to follow some extra steps. Installation works similar to normal pretix plugins, but involves a few extra steps.

Buying the license

To obtain a license, please get in touch at sales@pretix.eu. Please let us know how many tickets you roughly intend to sell per year and how many servers you want to use the plugin on. We recommend having a look at our price list first.

Manual installation

First, generate an SSH key for the system user that you install pretix as. In our tutorial, that would be the user pretix. Choose an empty passphrase:

# su pretix
$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/pretix/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /var/pretix/.ssh/id_rsa.
Your public key has been saved in /var/pretix/.ssh/id_rsa.pub.

Next, send the content of the public key to your sales representative at pretix:

$ cat /var/pretix/.ssh/id_rsa.pub
ssh-rsa AAAAB3N...744HZawHlD pretix@foo

After we configured your key in our system, you can install the plugin directly using pip from the URL we told you, for example:

$ source /var/pretix/venv/bin/activate
(venv)$ pip3 install -U "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack"
(venv)$ python -m pretix migrate
(venv)$ python -m pretix rebuild
# systemctl restart pretix-web pretix-worker

Docker installation

To install a plugin, you need to build your own docker image. To do so, create a new directory to work in. As a first step, generate a new SSH key in that directory to use for authentication with us:

$ cd /home/me/mypretixdocker
$ ssh-keygen -N "" -f id_pretix_enterprise

Next, send the content of the public key to your sales representative at pretix:

$ cat id_pretix_enterprise.pub
ssh-rsa AAAAB3N...744HZawHlD pretix@foo

After we configured your key in our system, you can add a Dockerfile in your directory that includes the newly generated key and installs the plugin from the URL we told you:

FROM pretix/standalone:stable
USER root
COPY id_pretix_enterprise /root/.ssh/id_rsa
COPY id_pretix_enterprise.pub /root/.ssh/id_rsa.pub
RUN chmod -R 0600 /root/.ssh && \
    mkdir -p /etc/ssh && \
    ssh-keyscan -t rsa -p 10022 code.rami.io >> /root/.ssh/known_hosts && \
    echo StrictHostKeyChecking=no >> /root/.ssh/config && \
    pip3 install -Ue "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack" && \
    cd /pretix/src && \
    sudo -u pretixuser make production
USER pretixuser

Then, build the image for docker:

$ docker build -t mypretix

You can now use that image mypretix instead of pretix/standalone:stable in your /etc/systemd/system/pretix.service service file. Be sure to re-build your custom image after you pulled pretix/standalone if you want to perform an update to a new version of pretix.
