Keycloak

Setting up Server

Install Podman=

sudo apt install podman

Create Image

podman pull quay.io/keycloak/keycloak
# Note I run tomcat so changed the ports from 8080
# quay.io/keycloak/keycloak:12.0.1

podman run -d \
  --name keycloak \
  -p 8081:8080 \
  -e KEYCLOAK_USER=admin \
  -e KEYCLOAK_PASSWORD=password \
  -e KEYCLOAK_IMPORT=/tmp/one-realm.json,/tmp/two-realm.json \
  quay.io/keycloak/keycloak:7.0.0

Moving to Docker

Stopping and starting

sudo docker-compose up -d
sudo docker-compose down

Could not get the keycloak to work in Podman so moved to docker

version: '3'
services:
  keycloak:
    image: jboss/keycloak:12.0.1
    ports:
      - "9999:8080"
    environment:
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: password
      KEYCLOAK_IMPORT: /tmp/one-realm.json,/tmp/two-realm.json
    volumes:
      - "./realms:/tmp"

version: '3'
services:
  keycloak:
    image: quay.io/keycloak/keycloak:12.0.1
    ports:
      - "9999:8080"
    environment:
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: password

Configure Keycloak

If using docker you need to change podman to docker Disable https

podman exec -it keycloak bash
cd /opt/jboss/keycloak/bin
./kcadm.sh config credentials --server http://localhost:8080/auth --realm master --user admin
./kcadm.sh update realms/master -s sslRequired=NONE

Generate a Token

I used online help to set the server up. Especially https://medium.com/devops-dudes/securing-node-js-express-rest-apis-with-keycloak-a4946083be51

   curl -X POST 'http://localhost:9999/auth/realms/one/protocol/openid-connect/token' \
 --header 'Content-Type: application/x-www-form-urlencoded' \
 --data-urlencode 'grant_type=password' \
  --data-urlencode 'client_id=app' \
 --data-urlencode 'client_secret=not this dummy' \
 --data-urlencode 'username=carol' \
 --data-urlencode 'password=carol' | jq
