# OC Catalog

## OpenCloud Catalog API

Uses the Beego framework

To install the Beego bee command : 

    go install github.com/beego/bee/v2@master

## Running the app locally 
In order to run the application we need to correct some errors that beego generates.

**Router generation**

Beego generates the routers from the comment of the controllers methods. However, there seems to be some errors when we let beego generate th routers from `bee run`. 

We need to use `bee generate routers` to have a working router file.

**Swagger generation**

Using `bee run -downdoc=true -gendoc=true` beego download a swagger template and generate the JSON file (swagger.json) in `swagger/`. However the swagger template in `swagger/index.html` does not change the exemple's url for our current JSON file. When running locally we have to edit the call to construct the object holding the swagger information, with the parameter url set with the relative path to our JSON swagger file :

```
const ui = SwaggerUIBundle({
        url: "swagger.json",
        ...
        ...
      });
```

This issue is fixed in the Dockerfile build with two `sed` to change the value of the swagger file URL.

## Deployment with Docker compose

Deploy with docker:
`docker-compose -f docker-compose.yml -f docker-compose.backend.yml up --build`

and populate DB (or other scripts) with:
`docker exec -it oc-catalog_oc-catalog_1 ./scripts/populate_models.sh ./scripts/demo.json`

or out of docker `./scripts/populate_models.sh ./scripts/demo.json`

### Dev

- Start DB with `docker-compose up -d` 
- Run the API with `bee run -downdoc=true -gendoc=true`


### Multinode

Deploy : 

`docker-compose -f docker-compose.yml -f docker-compose.backend.yml -f docker-compose.multi.yml up --build`

## Populating the MongoDB database

From the root of the projet run :

`./scripts/multinode.sh ./scripts/demo.json`

This script should be updated to be ran from anywhere.
