Docker Compose Configuration

You will often see, when for example configuring providers, that the environment variables will look like this:

INSTAGRAM_CLIENT_ID=12345678901234567890

You have 2 options on how to set these variables in your docker-compose.yml file.

Option 1: Direct in docker-compose.yml

You can set them directly in the environment section of the service.

services:
  postiz:
    environment:
      YOUR_ENV_VAR: "value"
      YOUR_OTHER_ENV_VAR: "value"

Option 2: Using a .env file

You can use a .env file to set the variables.

docker-compose.yml:

services:
  postiz:
    env_file:
      - .env

.env:

YOUR_ENV_VAR=value
YOUR_OTHER_ENV_VAR=value

Option 3: Combine both

You can also use both!

docker-compose.yml:

services:
  postiz:
    environment:
      YOUR_ENV_VAR: "value"
    env_file:
      - .env

.env:

YOUR_OTHER_ENV_VAR=value
