installing keycloak

requirements

apt install default-jdk-headless ?

you will also need a database engine e.g. mariadb

install

grab latest version

ver=26.6.3

cd /opt/
wget https://github.com/keycloak/keycloak/releases/download/$ver/keycloak-$ver.tar.gz
tar xzf keycloak-$ver.tar.gz
rm -f keycloak-$ver.tar.gz
ln -s keycloak-$ver /opt/keycloak

groupadd keycloak
useradd --system -g keycloak -d /opt/keycloak -s /sbin/nologin keycloak

expected user was UID 1001, which is not necessarily what we have

cd /opt/keycloak/
ls -lkF
mkdir data/
chown -R keycloak:keycloak LICENSE.txt README.md bin/ data/ lib/ version.txt
cd -
