Create a local development stack

dev/README.md

@@ -0,0 +1,66 @@
+This is a docker-compose configuration to be used **only** for development purpose. There is
+almost zero security in the stack configuration.
+
+It is composed of the Zimit frontend and API (of course), but also a local Zimfarm DB,
+API and UI, so that you can test the whole integration locally.
+
+Zimit UI and API are not deployed as they would be in production to allow hot reload of
+most modifications done to the source code.
+
+Zimfarm UI, API and DB are deployed with official production Docker images.
+
+## List of containers
+
+### zimit_ui
+
+This container is Zimit frontend web server (UI only)
+
+### zimit_api
+
+This container is Zimit API server (API only)
+
+## zimfarm_db
+
+This container is a local Zimfarm database
+
+## zimfarm_api
+
+This container is a local Zimfarm API
+
+## zimfarm_ui
+
+This container is a local Zimfarm UI
+
+## Instructions
+
+First start the Docker-Compose stack:
+
+```sh
+cd dev
+docker compose -p zimit up -d
+```
+
+If it is your first execution of the dev stack, you need to create a "virtual" worker in Zimfarm DB:
+
+```sh
+dev/create_worker.sh
+```
+
+If you have requested a task via Zimit UI and want to simulate a worker starting this task to observe the consequence in Zimit UI, you might use the `dev/start_first_req_task.sh`.
+
+## Restart the backend
+
+Should the API process fail, you might restart it with:
+```sh
+docker restart zimit-zimit_ui-1
+```
+
+## Browse the web UIs
+
+You might open following URLs in your favorite browser:
+
+- [Zimit UI](http://localhost:8001)
+- [Zimfarm API](http://localhost:8002)
+- [Zimfarm UI](http://localhost:8003)
+
+You can login into Zimfarm UI with username `admin` and password `admin`.
