v0.19.0

What's Changed

New features and Enhancements

• AuthConfig v1beta3, by @KevFan in #493
  • This is a new version of the API that is a superset of v1beta2, which means all AuthConfig resources based the older version (v1beta2) will continue to function. However, to be able to leverage the new features only in v1beta3, users should update their resources as soon as possible.
  • At some point after upgrading to v0.19.0, users are also invited to migrate their AuthConfigs stored in the cluster's database by running the following script. This will guarantee readiness for upgrading in the future to a newer version of Authorino where v1beta2 is no longer served.

    cat << 'EOF' > /tmp/migrate.sh
    #!/bin/bash
    authconfigs=$(kubectl get authconfigs -A -o custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name' --no-headers)
    while IFS=" " read -r namespace name; do
      kubectl get authconfig "$name" -n "$namespace" -o yaml > "/tmp/${name}.${namespace}.authconfig.yaml"
      kubectl apply -f "/tmp/${name}.${namespace}.authconfig.yaml"
    done <<< "$authconfigs"
    EOF
    chmod +x /tmp/migrate.sh
    /tmp/migrate.sh

  • Removal of AuthConfig v1beta1. Users in a older version of Authorino (< 0.18.0) must upgrade first to v0.18.0 ASAP, run the migration script to get stored resources bumped to v1beta2, and then upgrade to v0.19.0. Attempts to upgrade directly from older versions to v0.19.0 will fail.
  • Removal of the conversion webhook (deployed by the Authorino Operator) and therefore cert-manager is no longer a requirement for Authorino.
• Common Expression Language (CEL), by @alexsnaps in #495
  • when conditions and dynamic selector of values from the Authorization JSON now accept Common Expression Language (CEL). E.g.:

    apiVersion: authorino.kuadrant.io/v1beta3
    kind: AuthConfig
    metadata:
      name: my-authconfig
    spec:
      hosts: […]
      metadata:
        "authorized-ips":
          http:
            urlExpression: |
              "https://authorized-ips.default.cluster.local?nonce=" + request.id
      authorization:
        "acl":
          patternMatching:
            patterns:
            - predicate: source.address.split(":")[0] in auth.metadata["authorized-ips"]
          cache:
            key:
              expression: source.address.split(":")[0]
            ttl: 600
        "max-request-size":
          when:
          - predicate: request.method.lowerAscii() == "post"
          patternMatching:
            patterns:
            - predicate: request.size <= 1024

v0.18.0

What's Changed

New features and Enhancements

• AuthConfig v1beta2 API version became the new default version stored in the cluster database

  Important! After upgrading to Authorino v0.18.0, users must migrate all AuthConfig resources to v1beta2 stored in the cluster database by running the following script. This can be done at any time before upgrading to newer versions of Authorino post this one, without downtime or any intrinsic risk of breaking deployments before, during or after the migration.

  cat << 'EOF' > /tmp/migrate.sh
  #!/bin/bash
  authconfigs=$(kubectl get authconfigs -A -o custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name' --no-headers)
  while IFS=" " read -r namespace name; do
    kubectl get authconfig "$name" -n "$namespace" -o yaml > "/tmp/${name}.${namespace}.authconfig.yaml"
    kubectl apply -f "/tmp/${name}.${namespace}.authconfig.yaml"
  done <<< "$authconfigs"
  EOF
  chmod +x /tmp/migrate.sh
  /tmp/migrate.sh

What's Changed

New features and enhancements

• AuthConfig v1beta2 (by @guicassolato in #417, #431)
  • This is a big one that we've been cooking for quite some time! The AuthConfig API received a facelift and it now feels a lot more natural and declarative.
  • Example of resource based on the new API:

    apiVersion: authorino.kuadrant.io/v1beta2
    kind: AuthConfig
    metadata:
      name: my-app-protection
    spec:
      hosts:
      - my-app.io
      authentication:
        "friends":
          apiKey:
            selector:
              matchLabels:
                "app": "my-app"
          credentials:
            authorizationHeader:
              prefix: API-KEY
      authorization:
        "admin-only":
          patternMatching:
            patterns:
            - selector: auth.identity.metadata.annotations.group
              operator: eq
              value: admin
      response:
        unauthenticated:
          message:
            value: Authentication failed
        unauthorized:
          message:
            value: Access denied
        success:
          headers:
            "x-username":
              plain:
                selector: auth.identity.metadata.annotations.username

  • Highlights:
    • Lists/arrays of named definitions are now structured as objects
    • Dynamic values fetched from the Authorization JSON are now generally called selectors and replace the more complex valueFrom.authJSON.
    • spec.identity renamed as spec.authentication (with no consequence to the resolved identity object, which continues to be referred to as auth.identity in the Authorization JSON)
    • Several auth methods renamed and some slightly restructured for a more seamless UX
      • identity.oidc → authentication.jwt
      • identity.oauth2 → authentication.oauth2Introspection
      • identity.mtls → authentication.x509
      • identity.kubernetes → authentication.kubernetesTokenReview
      • identity.credentials{in, keySelector} → authentication.credentials{authorizationHeader | customHeader | queryString | cookie}
      • identity.extendedProperties → authentication.overrides and authentication.defaults
      • authorization.json{rules} → authorization.patternMatching{patterns}
      • authorization.kubernetes → authorization.kubernetesSubjectAccessReview
      • authorization.authzed → authorization.spicedb
    • Restructuring of spec.response
      • response.wrappers restructured as proper properties of new field response.success
      • denyWith{unauthenticated, unauthorized} → response{unauthenticated, unauthorized}
    • Few other minor enhancements preparing for the future, e.g.:
      • Unification of the configs for building HTTP clients
      • Full YAML/JSON data type compatibility for setting static values (so it behaves in the same way as when selecting a dynamic value from the Authorization JSON)
  • Backward compatibility:
    • [Deprecation warning] The old v1beta1 API continues to be served and, for at least one version, will be the schema of all stored resources – so users have time to upgrade their automation to v1beta2 before the next release. (More instructions to come soon.)
    • To support both versions of the APIs, a new conversion webhook service has been introduced. (Deployed automatically the Authorino Operator.)
• OR operator for when conditions (by @guicassolato in #427)
  • Another long-awaited feature! Conditionals now support disjunction (any).
  • E.g., to allow anonymous access (i.e., no authentication required) for all HTTP requests with path =~ '/test*' OR method == 'GET' (occasionally both can be true):

    spec:
      authentication:
        anonymous-request:
          when:
          - any:
            - selector: request.path
              operator: matches
              value: ^/test.*
            - selector: request.method
              operator: eq
              method: GET
          anonymous: {}

  • AND operation can still be enforced by specifying the new field all (default if omitted). E.g., including nested conditions, to express host == 'foo.apis.io' AND ((path =~ '/test*' AND (method == 'POST' OR method == 'PUT')) OR method == 'GET'):

    spec:
      authentication:
        anonymous-request:
          when:
          - selector: context.request.http.host
            operator: eq
            value: foo.apis.io
          - any:
            - all:
              - selector: context.request.http.path
                operator: matches
                value: ^/test.*
              - any:
                - selector: context.request.http.method
                  operator: eq
                  value: POST
                - selector: context.request.http.method
                  operator: eq
                  value: PUT
            - selector: context.request.http.method
              operator: eq
              value: GET
          anonymous: {}

• Well-known attributes (by @didierofrivia in #428)
  • Implements Kuadrant's Well-known Attributes for navigating the Authorization JSON
  • This not only enhances the AuthConfig API with more concise and comprehensible selectors, but will also give users of Kuadrant's AuthPolicy CRD a more seamless experience compared to the other APIs of the suite, such as the RateLimitPolicy CRD
  • [Deprecation warning] Deprecation of the context.* paths of the Authorization JSON – to be removed in future releases
• Enable/disable host name collision prevention for strict host subsets (by @guicassolato in #434)
  • New command-line flag --allow-superseding-host-subsets that disables the host name collision prevention for strict subsets of hosts attempted to be linked after a superset already taken.
  • Allows to create AuthConfigs first for a bigger set of host name domains, then supersede a subset of it with a second AuthConfig applied after
  • Recommended for specific use cases where other measures are in place to avoid users taking partial control of one another's auth schemes.

Full Changelog: v0.14.0...v0.15.0

v0.14.0

New features and Enhancements

• New response method plain (#393)
  • Allows configuring for the injection of HTTP request headers whose value are simple text/plain values.
  • This is an alternative to having to stringify a JSON object using the json response method.
• Control over overwriting values in the identity object added to the API (#399)
  • Adds new property overwrite: bool (default: false) to the extended properties that allows to force extend the identity object or only when the property is missing
• New tighten-up Permissions over Authorino files within the container (#391)
  • Adds a new dedicated home path in the file system within the container for the Authorino binary and any other future Authorino files.
  • The directory is owned by a new authorino Linux user and root Linux group.
  • Allows running Authorino on OpenShift with the default unprivileged user on standard restricted security context strategy, without the files having to be owned by root.
  • In other environments, users can choose to run the container as root or as the less privileged authorino user.
• [Breaking change] New escaping of base64-decoded strings (#401)
  • Authorino now automatically escapes double quotes within strings extracted from the Authorization JSON and decoded with the @base64 modifier.
  • The typical use case for this is to be able to parse base64-encoded strings that represent valid JSON types other than simple strings (e.g. objects and arrays) and navigate those structures with normal JSON paths. For example, for parsing a JWT straight from the Authorization header.
  • The new behavior comes with a minor breaking change though, which is the dropping of support for base64 URL-encoded values. As a consequence, base64-encoded strings, passed and extracted from the URL path to be decoded with the @base64 modifier, for example, must not include the URL-encoded right padding characters (i.e. =, encoded as %3D). Authorino will fail to decode such values. To work around this limitation, use the @replace modifier before decoding with @base64:decode.
• [Breaking change] Simple Kubernetes TokenReview identity object (#403)
  • Makes the Kubernetes TokenReview-based identity method to always fill the identity object from the status field of the TokenReview response, as opposed to the current hybrid behaviour of trying to detect whether the verified access token is a JWT or an opaque token.
  • Users relying on JWT detection can still extract, decode and parse the JWT directly from the Authorization header. Here’s an example extending the identity object. E.g.

    spec:
      identity:
      - name: k8s-tokenreview
        kubernetes:
          extendedProperties:
          - name: jwt
            valueFrom:
              authJSON: context.request.http.headers.authorization|@extract:{"pos":1}|@extract:{"sep":".","pos":1}|@base64:decode|@fromstr
