docker run --name keycloak -it -p 8443:8443 -v "$(pwd)"/.env:/env/.env -v "$(pwd)":/buildpack scalingo/scalingo-22:latest bash

And test in it:

bash buildpack/bin/detect
bash buildpack/bin/env.sh /env/.env /env
bash buildpack/bin/compile /build /cache /env
build/java/bin/keytool -genkeypair -storepass password -storetype PKCS12 -keyalg RSA -keysize 2048 -dname "CN=server" -alias server -ext "SAN:c=DNS:localhost,IP:127.0.0.1" -keystore /build/keycloak/conf/server.keystore
bash buildpack/bin/release

Run Keycloak server:

export PATH=$PATH:/build/java/bin
export KEYCLOAK_ADMIN=
export KEYCLOAK_ADMIN_PASSWORD=
export KC_DB=postgres
export KC_HOSTNAME=localhost
export KC_HOSTNAME_PORT=8443
build/keycloak/bin/kc.sh --verbose start
