How to run pushkin.io in Docker

This is an example of running pushkin.io on Docker and docker-compose

Explanation

I had to build pushkin from source code instead of using binary because there was no support for environment variables in config pushkinconfig.ini file. To enable environment variables I had to modify one line in lib/pushkin/pushkin/config.py:77 and then you can set e.g. db_port = %(PGPORT)s in the config file instead of hardcoding valus in Docker image.

Step 1: Generate a correct APN certificate

Follow steps from the pushkin documentation Setup certificates and replace the certs\apn_push\app_push_dev.pem file.

Step 2: Run docker-compose

In the root catalog (where the docker-compose.yml file is) run command

docker-compose up -d --build

this will build docker images (including postgres DB) and create docker containers.

Verify the pushkin.api container is up and running: docker ps. It should run on port 44001.

Step 3: Open a web browser

Open http://localhost:44001/get_request_queue to confirm the app is running correctly.

Step 4: Verify database

Verify that pushkin database was created in db.postgres container.
