Try your best to solve it. If you need hints, you will find the solution for this in the branch `simpleservices`, which you can obtain by running `git checkout simpleservices`. Note that after checking out this branch, you will have to start both the `movies` and `showtimes` microservices and then issue the curl request. The showtimes microservice will talk to movies microservice to deliver the final result.
+The main change needed is simple. We just have to issue an HTTP GET request to the movies API endpoint. We do this by changing `showtime_record` as follows:
+```python
+movies_service = "http://127.0.0.1:5001/movies/{}" #we know this is where the service is running. We replace the {} with the actual ID of the movie we want.
+
+def showtimes_record(date):
+ if date not in showtimes:
+ raise NotFound
+ print(showtimes[date])
+ result = []
+ for movie_id in showtimes[date]:
+ resp = requests.get(movies_service.format(movie_id))
+ result.append(resp.json()["title"])
+ return nice_json(result)
+```
## Step 3: Dockerization of microservices
+> We now have two microservices running on _localhost_ and talking to each other. If we need to move these services, it is not easy.
+> Your next task is to wrap these microservices as a docker image and make them portable. Essentially, this involves specifying all the dependencies and running parameters explicitly in a `Dockerfile`. You can have a go at this by copying from this [tutorial](https://www.docker.com/blog/containerized-python-development-part-1/). Or, switch to the `dockerservices` branch where you will find the solution for steps 3 and 4.
