How to update the Keycloak Package chart💣

Big Bang makes modifications to the upstream Codecentric helm chart. The upstream Keycloak image from IronBank is used in conjuction with a custom Keycloak plugin. The custom P1 plugin contains custom authz and authn code, custom self-registration theme, and automatic joining of groups based on certian registration information like the use of a DoD CAC. The plugin code is hosted at https://repo1.dso.mil/big-bang/apps/product-tools/keycloak-p1-auth-plugin. Platform One custom plugin artifact image is hosted in Iron Bank at registry1.dso.mil/ironbank/opensource/keycloak/keycloak:X.X.X. 1. Read release notes from upstream Keycloak documentation. Be aware of changes that are included in the upgrade. Take note of any manual upgrade steps that customers might need to perform, if any. 1. Be aware that there are currently two versions of Keycloak. One is the legacy version that uses Wildfly for the application server. The other version is the new one using Quarkus. Big Bang has migrated to the new Quarkus version. The images in Iron Bank have tag without the “legacy” X.X.X. 1. Create a development branch and merge request from the Keycloak issue if one was not already created by the renovate tool. 1. Do diff of upstream chart between old and new release tags to become aware of any significant chart changes. 1. Merge/Sync the new helm chart with the existing Keycloak package code. A graphical diff application like Meld is useful. Don’t use kpt to update. You can use Meld to sync changes directory by directory, file by dile, line by line. Reference the “Modifications made to upstream chart” section below. Be careful not to overwrite Big Bang Package changes that need to be kept. 1. When you are done manually syncing the helm chart update the chart/Kptfile manually with the new version and commit hash. 1. Update /CHANGELOG.md with an entry for “upgrade Keycloak to app version X.X.X chart version X.X.X-bb.X”. Or, whatever description is appropriate. 1. Update /chart/Chart.yaml to the appropriate versions. 

version: XX.X.X-bb.X
appVersion: XX.X.X-legacy
dependencies:
  - name: gluon
    version: "X.X.X"
annotations:
  bigbang.dev/applicationVersions: |
    - Keycloak: XX.X.X
  helm.sh/images: |
    - name: keycloak
    image: registry1.dso.mil/ironbank/opensource/keycloak/keycloak:XX.X.X
    - name: postgreslXX
    condition: postgresql.enabled
    image: registry1.dso.mil/ironbank/opensource/postgres/postgresqlXX:XX.XX
    - name: base
    condition: bbtests.enabled
    image: registry1.dso.mil/ironbank/big-bang/base:X.X.X
1. Update the /README.md following the gluon library script. You should update the README again at the end to pick up any additional chart changes you make during development testing. 1. Run a helm dependency command to update the chart/charts/*.tgz archives and create a new requirements.lock file. You will commit the tar archives along with the requirements.lock that was generated. 
helm dependency update ./chart
1. A custom Keycloak image is no longer used. Instead a plugin image is created and volume mounted into k8s. This Keycloak package chart uses the IronBank image. 1. If you are upgrading the Keycloak version follow instructions in the P1 plugin repo to upgrade the custom P1 plugin. Follow the instructions there for building a plugin jar for testing. Recommended to use the free community version of Intellij IDEA instead of Visual Studio Code. Intellij IDEA has much better support for Java development. You can run unit tests with coverage and build from IDE. 1. Test the plugin changes locally using the docker-compose local dev environment. Temporarily point the development/docker-compsose.yaml to the new plugin jar built during the previous step. 1. Test the admin console 1. Test the custom user forms - https://keycloak.bigbang.dev:8443/auth/realms/baby-yoda/account/ - https://keycloak.bigbang.dev:8443/auth/realms/baby-yoda/account/password - https://keycloak.bigbang.dev:8443/auth/realms/baby-yoda/account/totp - https://keycloak.bigbang.dev:8443/register 1. Test registering a user with CAC. Verify that the user is automatically added to IL2 group. Test login from the account page. 1. Test registering a regular user with username and password. Test login at the account page with OTP. 1. After you are satisfied with the testing in the docker compose environment, put a copy of the new plugin jar at development/plugin/p1-keycloak-plugin-X.X.X.jar. Then permanently point the docker-compose.yaml to that jar file so that the docker compose environment will work out of the box for anyone who clones this repo. 1. Build and publish a plugin image to the P1 Keycloak Plugin container registry using the instructions in the P1 plugin repo. The image label should have “test” in the name like this test-X.X.X. 1. Use a full k8s deployment to test Keycloak, the custom plugin, and end-to-end SSO. See next section. 1. After all testing search all the documentation and update any old Keycloak and plugin version numbers. 1. Make an official semver release tag in the p1 plugin repo and monitor the mirrored Party Bus IL2 pipeline to make sure it passes. To test the Party Bus pipeline with your development branch cut a release candidate tag from the branch like this X.X.X-rc.X. You can verify that the new plugin code will pass before merging the MR. 1. After all testing locally and k8s testing with a BigBang deployment has been completed publish an official plugin image in IronBank. The order that things should happen with BigBang MRs, BigBang release, and publishing plugin image in IronBank is still unclear. Brief instructions for IronBank pipeline maintenance: 1. The PartyBus IL2 MDO pipeline publishes the p1-keycloak-plugin-X.X.X.jar artifact back to the P1 Keycloak Package Registry. If PartyBus IL2 MDO pipeline is failing for reasons outside of our control, worst case, we can manualy publish to the plugin package registry. The BigBang MR will need the tests/test-values.yaml updated to use the new plugin init-container tag. The test values can use the image that was created in Big Bang Keycloak plugin container registry](https://repo1.dso.mil/big-bang/apps/product-tools/keycloak-p1-auth-plugin/container_registry/). There is no hard requirement to use the IronBank plugin image for the test values. 1. At the IronBank repo create a new issue with template “application update” 1. Create a branch and MR from the issue. 1. update hardening_manifest.yaml - the tag version - the label org.opencontainers.image.version - resources.url - resources.validation.value (use sha256sum to get the hash value of the jar file) 1. commit and push code changes 1. Verify that pipline passes 1. Complete checkbox items in the issue. You will need to request VAT “Vendor Contributor” access if there are any new findings that need justification. 1. Mark the MR as ready and apply label “Hardening:Review” to the MR and the issue. 1. Monitor the issue to make sure it keeps moving with the Container Hardening Team(CHT). 1. Don’t forget, the BigBang MR will need the tests/test-values.yaml updated to use the new plugin init-container tag. Can be either the test image or the image published in IronBank - registry.dso.mil/big-bang/apps/product-tools/keycloak-p1-auth-plugin/init-container:test-X.X.X - registry1.dso.mil/ironbank/big-bang/p1-keycloak-plugin:X.X.X

Testing new Keycloak version with custom P1 plugin.💣

  1. Create a k8s dev environment. One option is to use the Big Bang k3d-dev.sh with the -m for metalLB so that k3d can support multiple ingress gateways. The following steps assume you are using the script.
  2. Follow all of the instructions at the end of the script to connect to and use the remote k3d cluster.
  3. Deploy Big Bang with only istio-operator, istio, gitlab, sonarqube, and Mattermost enabled. Need to test both OIDC and SAML end-to-end SSO. Gitlab uses OIDC and Sonarqube uses SAML. Mattermost is included in the end-to-end testing because it has some unique SSO configuration that should be tested. Deploy BigBang using the following example helm command and the provided example big bang values override. Change the plugin image label to use your test plugin image. Hint: search for “X.X.X” in the example values file. 
    helm upgrade -i bigbang ./chart -n bigbang --create-namespace -f ../overrides/keycloak-bigbang-values.yaml -f ../overrides/registry-values.yaml -f ./chart/ingress-certs.yaml
  4. For end-to-end SSO testing there needs to be DNS for Keycloak. In a k3d dev environment there is no DNS so you must do a dev hack and edit the configmap “coredns-xxxxxxxx”. Under NodeHosts add a host for keycloak.bigbang.dev. 
    kubectl get cm -n kube-system
kubectl edit cm coredns -n kube-system
    The IP for the passthrough ingress gateway in a k3d environment created by the dev script will be 172.20.1.240. Like this 
      NodeHosts:|
    <nil> host.k3d.internal
    172.20.0.2 k3d-k3s-default-agent-0
    172.20.0.5 k3d-k3s-default-agent-1
    172.20.0.4 k3d-k3s-default-agent-2
    172.20.0.3 k3d-k3s-default-server-0
    172.20.0.6 k3d-k3s-default-serverlb
    172.20.1.240 keycloak.bigbang.dev
  5. Restart the coredns pod so that it picks up the new configmap. 
    kubectl get pods -A
kubectl delete pod <coredns pod> -n kube-system
  6. Sonarqube needs an extra configuration step for SSO to work because it uses SAML. The values override addons.sonarqube.sso.certificate needs to be updated with the Keycloak realm certificate. When Keycloak finishes installing login to the admin console Keycloak with default credentials admin/password. Navigate to Realm Settings >> Keys. On the RS256 row click on the Certificate button and copy the certificate text as a single line string and paste it into your addons.sonarqube.sso.certificate value. Run another helm upgrade command and watch for Sonarqube to update.
  7. In a browser load https://keycloak.bigbang.dev and register a test user. You should register yourself with CAC and also a non-CAC test.user with just user and password with OTP. Both flows need to be tested.
  8. Then go back to https://keycloak.bigbang.dev/auth/admin and login to the admin console with the default credentials admin/password
  9. Navigate to users, click “View all users” button and edit the test users that you created. Set “Email Verified” ON. Remove the verify email “Required User Actions”. Click “Save” button.
  10. Test end-to-end SSO with Gitlab and Sonarqube with your CAC user and the other test user.
  11. Test the custom user forms to make sure all the fields are working
    • https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/
    • https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/password
    • https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/totp
    • https://keycloak.bigbang.dev/register
  12. Occasionally the DoD certificate authorities will need to be updated. Follow the instructions at /scripts/certs/README.md and copy the new truststore.jks to ./chart/resources/dev and to https://repo1.dso.mil/big-bang/product/packages/keycloak/-/tree/18.4.3-bb.7/development/certs](https://repo1.dso.mil/big-bang/product/packages/keycloak/-/tree/18.4.3-bb.7/development/certs) . You might have to edit the /scripts/certs/dod_cas_to_pem.sh to update to the most recent published certs but it usually points to the latest archive.
