Docker Compose

Find out how to use Infisical to inject environment variables into services defined in your Docker Compose file.

Prerequisites:

• Set up and add envars to Infisical Cloud

Configure the Infisical CLI for each service

Follow this guide to configure the Infisical CLI for each service that you wish to inject environment variables into; you’ll have to update the Dockerfile of each service.

Generate service token

Generate a unique Infisical Token for each service.

Feed service token to your Docker Compose file

For each service you want to inject secrets into, set an environment variable called INFISICAL_TOKEN equal to a unique identifier variable.

In the example below, we set INFISICAL_TOKEN_FOR_WEB and INFISICAL_TOKEN_FOR_API as the INFISICAL_TOKEN for the services.

# Example Docker Compose file
services:
  web:
    build: .
    image: example-service-1
    environment:
      - INFISICAL_TOKEN=${INFISICAL_TOKEN_FOR_WEB}

  api:
    build: .
    image: example-service-2
    environment:
      - INFISICAL_TOKEN=${INFISICAL_TOKEN_FOR_API}

Export shell variables

Next, set the shell variables you defined in your compose file. This can be done manually or via your CI/CD environment. Once done, it will be used to populate the corresponding INFISICAL_TOKEN in your Docker Compose file.

#Example

# Token refers to the token we generated in step 2 for this service
export INFISICAL_TOKEN_FOR_WEB=<token>

# Token refers to the token we generated in step 2 for this service
export INFISICAL_TOKEN_FOR_API=<token>

# Then run your compose file in the same terminal.
docker-compose ...
