[x] Must define any external interfaces under the expose key.
[x] Must deploy and operate successfully with Istio injection enabled in the namespace.
[ ] Should avoid workarounds such as disabling strict mTLS peer authentication.
Network Policies
[x] Must define network policies under the allow key as required.
[x] Should minimize network policies to specific selectors needed for Ingress/Egress traffic.
[x] May template network policy keys to provide flexibility for delivery customers to configure.
Keycloak
[x] Must use and create a Keycloak client through the sso key if the application provides a user login.
[x] Should consider security options during implementation to provide the most secure default possible (i.e. SAML w/SCIM vs OIDC).
[x] Should name the client Login (i.e. Mattermost Login) to provide login UX consistency.
[x] Should clearly mark the client id with the group and app name uds-- (i.e. uds-swf-mattermost) to provide consistency in the Keycloak UI.
[x] May end any generated secrets with -sso to easily locate them when querying the cluster.
[x] May template Keycloak fields to provide flexibility for delivery customers to configure.
Prometheus
[x] Must implement monitors for each application metrics endpoint using it's built-in chart monitors, the Package CR monitor key, or manual monitors in the config chart.
Exemptions
UDS Packages may make use of the UDS Exemption custom resource for exempting any Pepr policies, but in doing so they:
[x] Must minimize the scope and number of the exemptions to only what is absolutely required by the application
[x] Must have documented rationale for any exemptions present
Structure
Packages also follow structural guidelines to ensure consistency and flexibility for configuration, they:
[x] Should expose all configuration (uds.dev CRs, additional Secrets/ConfigMaps, etc) through a Helm chart (ideally in a chart or charts directory).
[x] This allows UDS bundles to override configuration with Helm overrides and enables downstream teams to fully control their bundle configurations.
[x] Should limit the use of Zarf variable templates and prioritize configuring packages via Helm value overrides
[x] This ensures that the package is configured the same way that the bundle would be and avoids any side effect issues of Zarf's ### templating
[x] Should implement or allow for multiple flavors (ideally with common definitions in a common directory)
[x] This allows for different images or configurations to be delivered consistently to customers.
Testing
A UDS Package will also have testing and quality checks to ensure that updates / changes to them result in minimal churn. Packages:
[x] Must implement Journey Testing to cover the basic user flows and features of the application, especially where an application interacts with an external service / interface.
[x] This can by something like Playwright / Cypress tests for services with a Web UI or something like Jest tests for headless services.
[x] Must implement Upgrade Testing to ensure that the current development package works when deployed over the previously released one.
[x] Should lint their configurations with appropriate tooling such as yamllint and zarf dev lint.
Maintenance
To help maintain a UDS Package, it:
[x] Must have a dependency management bot (such as renovate) configured to open PRs to update core package and support dependencies.
[x] Must release its package to the ghcr.io/defenseunicorns/packages/ namespace as the application's name (i.e. ghcr.io/defenseunicorns/packages/uds/mattermost)
General
And in addition to the above, packages generally:
[x] Must be capable of operating within an internet-disconnected (air-gapped) environment
[x] Must be maintained by a resourced team that is explicitly defined as maintaining the project (i.e. in CODEOWNERS)
