How to update the Keycloak Package chart

BigBang makes modifications to the upstream Codecentric helm chart and also builds a custom image using the Iron Bank hardened image. The custom image contains a custom authentication plugin. Eventually the Platform One custom plugin code at ./development will be moved to an Iron Bank plugin pipeline. For now it remains in this repo.

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.
2. 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 for now will remain with the legacy version. The images in Iron Bank have tag with X.X.X-legacy.
3. Do diff of upstream chart between old and new release tags to become aware of any significant chart changes.
4. Create a development branch and merge request from the Keycloak issue.
5. Merge/Sync the new helm chart with the existing Keycloak package code. A graphical diff application like Meld is useful. Reference the “Modifications made to upstream chart” section below. Be careful not to overwrite Big Bang Package changes that need to be kept.
6. 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.

   export HELM_EXPERIMENTAL_OCI=1
   helm dependency update ./chart
   

7. Update /CHANGELOG.md with an entry for “upgrade Keycloak to app version X.X.X-legacy chart version X.X.X-bb.X”. Or, whatever description is appropriate.
8. 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-legacy
       - PlatformOne Plugin: X.X.X
   

9. Update the /README.md following the gluon library script
10. Update the /development/Earthfile. This is an Earthly config file. Earthly combines bash script and dockerfile together to make repeatable builds easy. Update PLUGIN_VERSION if the custom plugin code has changed. Update KEYCLOAK_VERSION to the new Iron Bank image tag. Update BIGBANG_VERSION as needed. These variables will be combined to create a composite custom image tag.
11. Update the keycloak library dependencies in the ./development/plugin/build.gradle to match the new version of Keycloak. This library update might cause build errors. You might have to fix code in src/main/**.java and src/test/**.java to get a build to complete without errors.
12. Build new image using Earthly by following the /development/README.md. If you are not doing Keycloak Java plugin development there is no need to install build tools on your workstation. A remote build server is recommended (EC2 instance) so that your workstation is not cluttered with build tools and artifacts. On the remote build server install Earthly. Git clone the Keyclok Package repository in the home directory on the remote build server and then change to the development directory. Switch to your development branch.

    git clone https://repo1.dso.mil/platform-one/big-bang/apps/security-tools/keycloak.git
    cd keycloak/development
    git checkout your-development-branch-name
    

    login to registry1 with your development pull credentials.

    docker login registry1.dso.mil
    

    Install Earthly on the remote build server. Run the Earthly build

    earthly +build-image
    

    If the build complets successfully the image will be saved to the remote build server.

    docker image list
    

    Verify that the image tag is unique in the repo1 registry. There are operational images in this image registry. Be 100% certian that you will not overwrite an existing tag.
    Login to Repo1 registry with your access token and push the image.

    docker login registry.dso.mil
    docker push registry.dso.mil/platform-one/big-bang/apps/security-tools/keycloak/keycloak-ib:X.X.X-X.X.X-X
    

13. Update the image tag in /chart/values.yaml to match the new tag you pushed to the registry.
14. Use a development environment to deploy and test Keycloak end-to-end SSO.

Testing new Keycloak version

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 ssh to the EC2 instance with application-level port forwarding. Keep this ssh session for the remainder of the testing. An example of the instructions to be followed are below.

SAVE THE FOLLOWING INSTRUCTIONS INTO A TEMPORARY TEXT DOCUMENT SO THAT YOU DON'T LOOSE THEM
NOTE: The EC2 instance will automatically terminate at 08:00 UTC unless you delete the cron job

ssh to instance:
ssh -i ~/.ssh/user.name-dev.pem ubuntu@X.X.X.X

To access apps from browser start ssh with application-level port forwarding:
ssh -i ~/.ssh/user.name-dev.pem ubuntu@X.X.X.X -D 127.0.0.1:12345

To use kubectl from your local workstation you must set the KUBECONFIG environment variable:
export KUBECONFIG=~/.kube/user.name-dev-config

Do not edit /etc/hosts on your local workstation.
To access apps from a browser edit /etc/hosts on the EC2 instance. Sample /etc/host entries have already been added there.
Manually add more hostnames as needed.

The IPs to use come from the istio-system services of type LOADBALANCER EXTERNAL-IP that are created when Istio is deployed.
You must use Firefox browser with with manual SOCKs v5 proxy configuration to localhost with port 12345.
Also ensure 'Proxy DNS when using SOCKS v5' is checked.
Or, with other browsers like Chrome you could use a browser plugin like foxyproxy to do the same thing as Firefox.

1. You will need to edit the /etc/hosts on the EC2 instance. Make it look like this

   ## begin bigbang.dev section
   172.20.1.240 keycloak.bigbang.dev
   172.20.1.241 gitlab.bigbang.dev sonarqube.bigbang.dev
   ## end bigbang.dev section
   

2. 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 keycloak in a k3d environment created by the dev script will be 172.20.1.240. Like this yaml 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

1. Restart the coredns pod so that it picks up the new configmap.

kubectl get pods -A
kubectl delete pod <coredns pod> -n kube-system

1. Deploy Big Bang with only istio-operator, istio, gitlab, and sonarqube enabled. Need to test both OIDC and SAML end-to-end SSO. Gitlab uses OIDC and Sonarqube uses SAML. Deploy BigBang using the following example helm command

helm upgrade -i bigbang ./chart -n bigbang --create-namespace -f ../overrides/my-bb-override-values.yaml -f ../overrides/registry-values.yaml -f ./chart/ingress-certs.yaml

1. 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.
2. Use Firefox browser with SOCKS v5 manual proxy configured so that we are running Firefox as if it was running on the EC2 instance. This is described in more detail in the development environment addendum Multi Ingress-gateway Support with MetalLB and K3D
3. In the Firefox 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.
4. Then go back to https://keycloak.bigbang.dev/auth/admin and login to the admin console with the default credentials admin/password
5. 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.
6. Test end-to-end SSO with Gitlab and Sonarqube with your CAC user and the other test user.
7. Test the custom user forms to make sure all the fields are working
8. https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/
9. https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/password
10. https://keycloak.bigbang.dev/auth/realms/baby-yoda/account/totp
11. 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 dod_cas.pem to chart/resources/dev. You might have to edit the /scripts/certs/dod_cas_to_pem.sh to update to the most recent published certs.
