docker_postgres_14_cron

Creates a new Docker image based on Postgres:14.7 and adds pg_cron support. The logic is the same for almost all Postgres versions. You could use it with Postgres-13, Postgres-15 as well. Don't forget to change Postgres version numbers in Dockerfile, and build.sh.

How to use?

1 - Build your own image & use the image with docker-compose

• clone the repo
• use build.sh to create the image
• create an .env file along with docker-compose.yml
• add POSTGRES_CRON_DB=cron_db_name to the .env
• add POSTGRES_CRON_DB to the environment section in docker-compose.yml
• refer to the image in docker-compose.yml

version: '3.6'
services:
  postgres:
    image: postgres_cron:14.7
    ...
    ...
    ..
  environment:
    POSTGRES_CRON_DB: ${POSTGRES_CRON_DB}

• run docker-compose up -d

2 - Use the Github container repo version

• create an .env file along with docker-compose.yml
• add POSTGRES_CRON_DB=cron_db_name to the .env
• add POSTGRES_CRON_DB to the environment section in docker-compose.yml
• refer to the image in docker-compose.yml

version: '3.6'
services:
  postgres:
    image: ghcr.io/circleboom/docker-postgres-14-with-pg_cron
    ...
    ...
    ..
  environment:
    POSTGRES_CRON_DB: ${POSTGRES_CRON_DB}
