How can we test changes to the XIR project in the VTE?

## Python/MX Only Changes

For changes in XIR that are purely at the Python/MX stage. All that is needed is to install the development version of python in the `model` container in the portal.

The definition of this container is here.

- [https://gitlab.com/mergetb/engine/-/blob/master/containers/model.dock](https://gitlab.com/mergetb/engine/-/blob/master/containers/model.dock)

To create a version of this container with the development version of Python/MX you could comment out the `pip3 install mergexp` that grabs MX from PyPi and install from your git repo. Assuming you have your own fork of XIR you can do something like this

```auto
#RUN pip3 install mergexp
WORKDIR /
RUN git clone https://gitlab.com/rygoo/xir
WORKDIR /xir
RUN git checkout my-working-branch
WORKDIR /xir/lang/mx
RUN pip3 install .

```

Then

- Build the container and push it to a container registry such as Docker Hub or Quay
- On the portal k8s master do a `merge-t2.kubectl edit deployment model`, which will drop you into an editor where you can look for the tag `image:`, and edit the container image URI to the image you just pushed.

Alternatively you can exec into the container and install your development version of Python/MX over the top of the PyPi installed version.

## Golang Changes

Changes to the Golang code require more consideration. I’ll update this post upon request for that.
