Prefect 2.0 docker compose deployment

Scripts to deploy Prefect 2.0 locally configured with Postgres, a docker agent, and Minio for flow storage

Requirements

* docker
* docker-compose
* make

Steps

* Clone this repo
* Add folowing entry to your /etc/hosts:
    127.0.0.1 prefect-server
* Cd into the prefect-orion folder
* Build docker image used by prefect server, agent and flow runner
    ```
    make docker
    ```
* Start the stack
    ```
    ./prefect.sh start
    ```
    The prefect.sh script initializes postgres and starts all services. Data (postgres, minio) is stored in a folder named `volumes`
* Give the start command a few seconds, specially the first time since postgres and prefect need to be initializated
* Open http://prefect-server:4200 in your browser and verify Prefect UI is up and running
* Deploy test flow and deployment
    ```
    make register-test-flow
    ```
    A flow named `my-docker-flow` and a `my-docker-flow/docker-example` deployment should have been created
* Create a flow run from the `Deployments` screen by selecting the deployment and clicking on `Run`


* To stop the services run `./prefect.sh stop`
* To reset your environment, run `./prefect.sh reset && ./prefect.sh start`. A fresh deployment will start up.

Notes

* If running in linux, you may need to run as root depending on docker permissions
