Keycloak- Invalid config for has Algorithm: Password hashing provider not found

I am running keycloak on docker, and I want to import a realm, previously exported. But I get the error: Error during startup: org.keycloak.models.ModelException: Invalid config for hashAlgorithm: Password hashing provider not found I read that I needed to copy jbcrypt.jar to the container, in standalone/deployments folder. I then created a Dockerfile with the, so I could copy jbcrypt. Please how can I provide a password hashing provider for bcrypt?.

Dockerfile:

FROM jboss/keycloak:latest

ARG KEYCLOAK_HOME=/opt/jboss/keycloak
RUN curl -L https://github.com/leroyguillaume/keycloak-bcrypt/releases/download/1.5.0/keycloak-bcrypt-1.5.0.jar > $KEYCLOAK_HOME/standalone/deployments/keycloak-bcrypt-1.5.0.jar
RUN curl -L https://repo1.maven.org/maven2/org/mindrot/jbcrypt/0.4/jbcrypt-0.4.jar > $KEYCLOAK_HOME/standalone/deployments/jbcrypt-0.4.jar

RUN cd $KEYCLOAK_HOME/standalone/deployments/ && ls
RUN /opt/jboss/keycloak/bin/jboss-cli.sh --command="module add --name=org.mindrot.jbcrypt --resources=$KEYCLOAK_HOME/standalone/deployments/jbcrypt-0.4.jar"

      # Uncomment the line below if you want to specify JDBC parameters. The parameter below is just an example, and it shouldn't be used in production without knowledge. It is highly recommended that you read the PostgreSQL JDBC driver documentation in order to use it.

Solution

  • I've used volume in docker-compose to get it working without restart Download the lib from GitHub and mount as a volume like below:

    volumes:
- ./keycloak-bcrypt-1.5.0.jar:/opt/jboss/keycloak/standalone/deployments/keycloak-bcrypt-1.5.0.jar
