Developer guide for running the Credential Service

Run as standalone application using Docker Compose

If you want to run the application without any external databases or dependent services, we provide a Docker Compose file to spin up a standalone service.
docker compose -f docker/no-external-db/docker-compose-no-db.yml up --detach
This standalone service uses an in-memory database with no persistence, and therefore is recommended only if you're managing key/secret storage separately.
The no-db.env file in the same folder contains all the environment variables necessary to configure the service. (See section Configuration above.)

Run with external Key Management System (KMS) and/or authentication service using Docker Compose

Construct the postgres URL and configure the env variables mentioned above.
Spinning up a Docker container from the pre-built credential-service Docker image on Github is as simple as the command below:

Configure PostgreSQL database

Configure the environment variables in the postgres.env file:
  1. 1.
    POSTGRES_USER: Username for Postgres database
  2. 2.
    POSTGRES_PASSWORD: Password for Postgres database
  3. 3.
    POSTGRES_MULTIPLE_DATABASES: Database names for multiple databases in the same cluster, e.g.: "app,logto". This sets up multiple databases in the same cluster, which can be used independently for External Veramo KMS or LogTo service.
Then, make the Postgres initialisation scripts executable:
chmod +x docker/with-external-db/pg-init-scripts/create-multiple-postgresql-databases.sh

Start LogTo service

Configure the environment variables in the logto.env file with the settings described in section above.
Then, run the LogTo service to configure the LogTo application API resources, applications, sign-in experiences, roles etc using Docker Compose:
docker compose -f docker/with-external-db/docker-compose-with-db.yml --profile logto up --detach
Configuring LogTo is outside the scope of this guide, and we recommend reading LogTo documentation to familiarise yourself.

Start credential-service app

Configure the environment variables in the with-db.env file with the settings described in section above. Depending on whether you are using external Veramo KMS only, LogTo only, or both you will need to have previously provisioned these services as there are environment variables in this file that originate from Postgres/LogTo.
Then, start the service using Docker Compose:
docker compose -f docker/with-external-db/docker-compose-with-db.yml up --detach

Running app or LogTo migrations

When upgrading either the external Veramo KMS or LogTo, you might need to run migrations for the underlying databases.
You can run just the migration scripts using Docker Compose profiles defined in the Compose file.
For example, to run Credential Service app migrations on an existing Postgres database (for external Veramo KMS):
docker compose -f docker/with-external-db/docker-compose-with-db.yml --profile app-setup up --detach
Or to run LogTo migrations on an existing Postgres database:
docker compose -f docker/with-external-db/docker-compose-with-db.yml --profile logto-setup up --detach

Build using Docker

To build your own image using Docker, use the Dockerfile provided.
docker build --file docker/Dockerfile --target runner . --tag credential-service:local
