Setup Keycloak for development purposes

Keycloak docker-compose

Just paste code below to file and name it docker-compose.yml

services:
  keycloak:
    image: quay.io/keycloak/keycloak:26.0
    environment:
      KC_BOOTSTRAP_ADMIN_USERNAME: admin
      KC_BOOTSTRAP_ADMIN_PASSWORD: admin
    ports:
      - '8000:8080'
    command:
      - start-dev

Run command docker compose up -d and open in the browser url http://localhost:8000. Login to the keycloak with user and password - in a file both are admin.

Keycloak internal setup

1. Create the realm Fill the name and click create.
2. Create the client Click clients in a sidebar and click Create client. Fill the Client ID, which is very important and commonly used in oauth libraries. This settings I would leave that way, because the most popular and used everywhere is code flow which is in standard flow checkbox. Next you should determine your URIs. For Angular it can look like this:

3. Create the user There's nothing complicated here, just fill the inputs.

4. Create a password for the user In the Credentials tab you are able to set the password for your user.

That's it! You are good to go with a development :)
