keycloak-config-cli

keycloak-config-cli is a Keycloak utility to ensure the desired configuration state for a realm based on a JSON/YAML file. The format of the JSON/YAML file based on the export realm format. Store and handle the configuration files inside git just like normal code. A Keycloak restart isn't required to apply the configuration.

Config files

The config files are based on the keycloak export files. You can use them to re-import your settings. But keep your files as small as possible. Remove all UUIDs and all stuff which is default set by keycloak.

moped.json is a full working example file you can consider. Other examples are located in the test resources.

Variable Substitution

keycloak-config-cli supports variable substitution of config files. This could be enabled by import.var-substitution.enabled=true (disabled by default).

Variables exposed by spring boot (through configtree or external configuration) can be accessed by $(property.name).

In additional, the string substitution support multiple prefixes for different approaches

Base64 Decoder:        $(base64Decoder:SGVsbG9Xb3JsZCE=)
Base64 Encoder:        $(base64Encoder:HelloWorld!)
Java Constant:         $(const:java.awt.event.KeyEvent.VK_ESCAPE)
Date:                  $(date:yyyy-MM-dd)
DNS:                   $(dns:address|apache.org)
Environment Variable:  $(env:USERNAME)
File Content:          $(file:UTF-8:src/test/resources/document.properties)
Java:                  $(java:version)
Localhost:             $(localhost:canonical-name)
Properties File:       $(properties:src/test/resources/document.properties::mykey)
Resource Bundle:       $(resourceBundle:org.example.testResourceBundleLookup:mykey)
Script:                $(script:javascript:3 + 4)
System Property:       $(sys:user.dir)
URL Decoder:           $(urlDecoder:Hello%20World%21)
URL Encoder:           $(urlEncoder:Hello World!)
URL Content (HTTP):    $(url:UTF-8:http://www.apache.org)
URL Content (HTTPS):   $(url:UTF-8:https://www.apache.org)
URL Content (File):    $(url:UTF-8:file:///$(sys:user.dir)/src/test/resources/document.properties)
XML XPath:             $(xml:src/test/resources/document.xml:/root/path/to/node)

to replace the values with java system properties or environment variables. Recursive variable replacement like $(file:UTF-8:$(env:KEYCLOAK_PASSWORD_FILE)) is enabled by default if import.var-substitution.enabled is set to true.

The variable substitution is running before the json parser gets executed. This allows json structures or complex values.

See Apache Common StringSubstitutor documentation for more information and advanced usage.

Note: Since variable substitution is a part of the keycloak-config-cli, it's done locally. This means, the environment variables need to be available where keycloak-config-cli is executed.

If import.var-substitution.prefix=${ and import.var-substitution.suffix=} (default in keycloak-config-cli 3.x) is set, then keycloak builtin variables like ${role_uma_authorization} needs to be escaped by $${role_uma_authorization}.

Logging

JSON logging support

keycloak-config-cli supports logging in JSON format. To enable, set SPRING_PROFILES_ACTIVE=json-log.

Log level

CLI Option	ENV Variable	Description	Default
--logging.level.root	LOGGING_LEVEL_ROOT	define the root log level	`info`
--logging.level.keycloak-config-cli	LOGGING_LEVEL_KEYCLOAKCONFIGCLI	log level of keycloak-config-cli components	value of `logging.level.root`
--logging.level.http	LOGGING_LEVEL_HTTP	log level http requests between keycloak-config-cli and Keycloak	value of `logging.level.root`
--logging.level.realm-config	LOGGING_LEVEL_REALMCONFIG	if set to trace, the realm config including sensitive information will be logged	value of `logging.level.root`

Supported features

See: docs/FEATURES.md

Compatibility with keycloak

Since keycloak-config-cli 4.0 will support the latest 4 releases of keycloak, if possible. There are some exceptions:

keycloak-config-cli will try the keep an extended support for RH-SSO
keycloak-config-cli will cut the support if keycloak introduces some breaking changes

Build this project

keycloak-config-cli using maven to build and test keycloak-config-cli. In case maven is not installed on your system, the mvnw command will download maven for you.

Further development requirements

Java Development Kit (JDK)
Docker Desktop or an alternative replacement (e.g Rancher Desktop)

Before running mvn verify, you have to set the JAVA_HOME environment variable to prevent some test failures.

./mvnw verify

# Windows only
mvnw.cmd verify

If your are working with a Docker Desktop replacement, some of the Integrationtests can fail due to internal DNS Lookups (host.docker.internal is not reachable). In this case the host can be replaced by a property.

mvn verify -DJUNIT_LDAP_HOST=an.alternate.host.or.ip

Run integration tests against real keycloak

We are using TestContainers in our integration tests. To run the integration tests a configured docker environment is required.

./mvnw verify

# Windows only
mvnw.cmd verify

Run this project

Start a local keycloak on port 8080:

docker-compose down --remove-orphans && docker-compose up keycloak

before performing following command:

java -jar ./target/keycloak-config-cli.jar \
    --keycloak.url=http://localhost:8080 \
    --keycloak.ssl-verify=true \
    --keycloak.user=admin \
    --keycloak.password=admin123 \
    --import.files.locations=./contrib/example-config/moped.json

Docker

A docker images is available at DockerHub (docker.io/adorsys/keycloak-config-cli) and quay.io (quay.io/adorsys/keycloak-config-cli)

Available docker tags

Tag	Description
`latest`	latest available release of keycloak-config-cli which is built against the latest supported Keycloak release.
`latest-x.y.z`	latest available release of keycloak-config-cli which is built against the Keycloak version `x.y.z`.
`edge`	latest commit on the main branch and which is built against the latest supported Keycloak release.
`a.b.c`	keycloak-config-cli version `a.b.c` which is built against the latest supported Keycloak release.
`a.b.c-x.y.z`	keycloak-config-cli version `a.b.c` which is built against the Keycloak version `x.y.z`.
`maven`	See below

Additionally, the tag maven contains the source code and compile keycloak-config-cli at runtime. This has the advantage to keycloak-config-cli with Keycloak versions, that not official supported., e.g.:

docker run --rm -ti -v $PWD:/config/ -eKEYCLOAK_VERSION=23.0.1 -eMAVEN_CLI_OPTS="-B -ntp -q" adorsys/keycloak-config-cli:edge-build

Docker run

For docker -e you have to replace dots with underscores.

docker run \
    -e KEYCLOAK_URL="http://<your keycloak host>:8080/" \
    -e KEYCLOAK_USER="<keycloak admin username>" \
    -e KEYCLOAK_PASSWORD="<keycloak admin password>" \
    -e KEYCLOAK_AVAILABILITYCHECK_ENABLED=true \
    -e KEYCLOAK_AVAILABILITYCHECK_TIMEOUT=120s \
    -e IMPORT_FILES_LOCATIONS='/config/*' \
    -v <your config path>:/config \
    adorsys/keycloak-config-cli:latest

Docker build

You can build an own docker image by running

docker build -t keycloak-config-cli .

Helm

We provide a helm chart here.

Since it makes no sense to deploy keycloak-config-cli as standalone application, you could add it as dependency to your chart deployment.

Checkout helm docs about chart dependencies!

See application.properties for all available settings.

For docker -e you have to remove hyphens and replace dots with underscores.

Take a look at spring relax binding or binding from Environment Variables if you need alternative spellings.

Configure properties values through files

By define an environment variable SPRING_CONFIG_IMPORT=configtree:/run/secrets/, the values of properties can be provided via files instead of plain environment variable values.

Example: To configure the property keycloak.password in this case, the file should be in /run/secrets/keycloak.password.

The configuration and secret support in Docker Swarm is a perfect match for this use case.

Checkout the spring docs to get more information about the configuration trees feature in spring boot.

Perform release

Building releases requires gpg signing.

Example to create and add a key to yout git config on MacOS

brew install gnupg
gpg --version
gpg --full-generate-key
# follow instructions
gpg --list-keys
gpg --list-secret-keys --keyid-format=short
# check the 8 digit code eg "ssb   xxxxxxx/E51442F5 2022-01-01 [X]"
git config --global user.signingkey E51442F5

Finally add the key to your Github account under Settings -> SSH and GPG keys -> New GPG key

Create release via maven release plugin:

./mvnw -Dresume=false release:prepare release:clean
git push --follow-tags
