HELM Charts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, you need to get access to the HELM charts.
They are hosted in a private :term:`Git` repository.
You'll get access by sharing a public key with us.

1. Create a new public/private key (that way, there won't be a conflict with already registered keys at GitHub): ``ssh-keygen -t ed25519 -f my-key``
2. Send your new ``my-key.pub`` public key to the contact person at Sagemath, Inc.
   This key will be added as a deployment key.
3. Then, in a new empty directory (e.g. ``cocalc-onprem``):

.. code:: bash

    git init .
    git config --local core.sshCommand "ssh -i ~/path/to/my-key"
    git remote add github git@github.com:sagemathinc/cocalc-onprem-helm.git
    git pull github main
    git branch --set-upstream-to=github/main

(replace ``~/path/to/my-key`` by the path to the private key generated in step 2.)

Once this is done, pull periodically to get updates and :ref:`update the deployed HELM chart <updating>`.
In particular, the tags for the deployed docker images will change – see :doc:`../ops/versions` for more details.
