Creating a Keycloak Theme

  1. Mount a local theme to the container (assuming keycloak already running)

    # Create directory for the theme mkdir my-theme

    docker container list docker commit docker run -d -p 5000:8080 --mount type=bind,source=,target=

  2. Disable Cache

The original values are:


Set it to:


Copy the file to the host:

docker cp <container>:opt/jboss/keycloak/standalone/configuration/standalone.xml .

Send back with:

docker cp standalone.xml <container>:/opt/jboss/keycloak/standalone/configuration/standalone.xml
  1. Make the login theme

    cd mkdir login cd login vi

Add the following:


Then go to login. Then change parent=keycloak and it should change.

For me I had to restart the keycloak service.

  1. Add CSS

add the file themes/mytheme/login/resources/css/styles.css

.login-pf body {
    background: DimGrey none;

then edit


This removes overrides all the styles of the parent. So you can add them again with: node_modules/patternfly/dist/css/patternfly.css node_modules/patternfly/dist/css/patternfly-additions.css lib/zocial/zocial.css css/login.css css/styles.css

  1. Add IMages

Add to themes/mytheme/login/resources/img

You can then use the image with:

body {
    background-image: url('../img/image.jpg');
    background-size: cover;


<img src="${url.resourcesPath}/img/image.jpg">
