Running locally with Docker

Authgear is available as a Docker image. It depends on PostgreSQL and Redis. To run it locally, the simplest way is to use docker-compose.
Create the project directory
Let's get started with creating a new directory.
1
mkdir myapp
2
cd myapp
Copied!
Create authgear.yaml and authgear.secrets.yaml
First, we need to create authgear.yaml and authgear.secrets.yaml. Authgear itself is a CLI program capable of generating a minimal configuration file.
Run the following command to generate a minimal authgear.yaml:
1
docker run --rm -it -w "/work" -v "$PWD:/work" quay.io/theauthgear/authgear-server authgear init config
Copied!
authgear.yaml is generated in your working directory.
Run the following command to generate a minimal authgear.secrets.yaml:
1
docker run --rm -it -w "/work" -v "$PWD:/work" quay.io/theauthgear/authgear-server authgear init secrets
Copied!
authgear.secrets.yaml is now generated in your working directory.
Create docker-compose.yaml
The next step is to create docker-compose.yaml to setup PostgreSQL, Redis, and Authgear.
You can start with the following docker-compose.yaml:
1
version: "3"
2
services:
3
  db:
4
    image: postgres:12.3
5
    volumes:
6
      - db_data:/var/lib/postgresql/data
7
    environment:
8
      POSTGRES_USER: "postgres"
9
      POSTGRES_PASSWORD: "postgres"
10
    ports:
11
      - "5432:5432"
12
​
13
  redis:
14
    image: redis:5.0
15
    volumes:
16
      - redis_data:/data
17
    ports:
18
      - "6379:6379"
19
​
20
  authgear:
21
    # Remember to replace the latest tag with the exact version you would like to use!
22
    image: quay.io/theauthgear/authgear-server:latest
23
    volumes:
24
      - ./authgear.yaml:/app/authgear.yaml
25
      - ./authgear.secrets.yaml:/app/authgear.secrets.yaml
26
    environment:
27
      DEV_MODE: "true"
28
      LOG_LEVEL: "debug"
29
    ports:
30
      - "3000:3000"
31
​
32
volumes:
33
  redis_data:
34
    driver: local
35
  db_data:
36
    driver: local
Copied!
Edit authgear.secrets.yaml
The three services run in the same network. We have to ensure Authgear can connect to PostgreSQL and Redis.
Check authgear.secrets.yaml and see if it looks like the following:
1
secrets:
2
- key: db
3
  data:
4
    database_schema: public
5
    database_url: postgres://postgres:[email protected]:5432/postgres?sslmode=disable
6
- key: redis
7
  data:
8
    host: redis
9
    port: 6379
10
# Other entries that are randomly generated.
11
# They are not listed here because they will be different.
Copied!
Start PostgreSQL and Redis
Authgear depends on them so they have to be started first.
1
docker-compose up -d db redis
Copied!
Run database migration
Run the database migration:
1
docker-compose run --rm  authgear authgear migrate up
Copied!
Get it running
Run everything with:
1
docker-compose up
Copied!
Verify everything is working
Visit http://localhost:3000 and try signing up as a new user!
