ZeroFactor.Aspire.Hosting

Aspire hosting integration for 0factor, a mock OIDC provider for local development. Login is an email address only. URLs, discovery, tokens and realm import are Keycloak-compatible, so swapping Keycloak for 0factor is one line in the AppHost.

Never use 0factor in production.

// dotnet add package ZeroFactor.Aspire.Hosting
var keycloak = builder.AddZeroFactor("keycloak")    // was: builder.AddKeycloak("keycloak", 8080)
    .WithRealmImport("./Realms")                    // same realm files Keycloak uses
    .WithDataVolume();

builder.AddProject<Projects.Web>("web")
    .WithReference(keycloak)
    .WaitFor(keycloak);

App projects keep the official Aspire.Keycloak.Authentication package unchanged:

builder.Services.AddAuthentication()
    .AddKeycloakOpenIdConnect("keycloak", realm: "shop", options => { /* ... */ });
Method Container
AddZeroFactor(name, port) docker.io/c4l3b/0factor:<package version>, endpoint http → 8080, health check /health
WithRealmImport(path) copies files to /opt/keycloak/data/import
WithDataVolume(name) / WithDataBindMount(source) mounts /data (holds 0factor.json)

Without port, the host port is derived from the AppHost directory and resource name (20000–29999): stable across restarts, and different for each AppHost on the machine, so several projects can run at once without coordinating ports. Pass port: 8080 to keep Keycloak's exact URL, or pass a port if two AppHosts ever collide.

Requires Aspire 13.4.6 or later. The endpoint is unproxied, so Aspire integration tests keep the port. For a port Aspire allocates on every run, use AddZeroFactor(name, port: null, isProxied: true). ZF_HOSTNAME is set automatically to the host endpoint; a later WithEnvironment can override it.

For apps using stock OIDC/JwtBearer handlers:

builder.AddProject<Projects.Web>("web")
    .WithReference(keycloak, realm: "shop")
    .WaitFor(keycloak);
// Web: builder.Configuration.GetConnectionString("keycloak") is the issuer.

This adds realm users and discovery links to the dashboard. The provider also links to user management. For a custom environment setting, use .WithEnvironment("Auth__Authority", keycloak.GetIssuer("shop")). Issuer references resolve to the allocated host address, intended for local project consumers.

See the main README for import precedence, explicit realm leniency, audience shorthand and migration from other mocks.
