OpenShift Ansible Broker Configuration | Configuring Clusters

Overview

When the OpenShift Ansible broker (OAB) is deployed in a cluster, its behavior is largely dictated by the broker’s configuration file loaded on startup. The broker’s configuration is stored as a configmap object in the broker’s namespace (ansible-service-broker by default).

Authenticating on Red Hat Partner Connect Registry

Before configuring the Automation Broker, you must run the following command on all nodes of an OKD cluster to use the Red Hat Partner Connect:

$ docker --config=/var/lib/origin/.docker login -u <registry-user> -p <registry-password> registry.connect.redhat.com

Modifying the OpenShift Ansible Broker Configuration

To modify the OAB’s default broker configuration after it has been deployed:

Edit the broker-config configmap object in the OAB’s namespace as a user with cluster-admin privileges:
```
$ oc edit configmap broker-config -n ansible-service-broker
```
After saving any updates, redeploy the OAB’s deployment configuration for the changes to take effect:
```
$ oc rollout latest dc/asb -n ansible-service-broker
```

Registry Configuration

The registry section allows you to define the registries that the broker should look at for APBs.

Table 1. `registry` Section Configuration Options
Field	Description	Required
`name`	The name of the registry. Used by the broker to identify APBs from this registry.	Y
`user`	The user name for authenticating to the registry. Not used when `auth_type` is set to `secret` or `file`.	N
`pass`	The password for authenticating to the registry. Not used when `auth_type` is set to `secret` or `file`.	N
`auth_type`	How the broker should read the registry credentials if they are not defined in the broker configuration via `user` and `pass`. Can be `secret` (uses a secret in the broker namespace) or `file` (uses a mounted file).	N
`auth_name`	Name of the secret or file storing the registry credentials that should be read. Used when `auth_type` is set to `secret`.	N, only required when `auth_type` is set to `secret` or `file`.
`org`	The namespace or organization that the image is contained in.	N
`type`	The type of registry. Available adapters are `mock`, `rhcc`, `openshift`, `dockerhub`, and `local_openshift`.	Y
`namespaces`	The list of namespaces to configure the `local_openshift` registry type with. By default, a user should use `openshift`.	N
`url`	The URL that is used to retrieve image information. Used extensively for RHCC while the `dockerhub` type uses hard-coded URLs.	N
`fail_on_error`	Should this registry fail, the bootstrap request if it fails. Will stop the execution of other registries loading.	N
`white_list`	The list of regular expressions used to define which image names should be allowed through. Must have a white list to allow APBs to be added to the catalog. The most permissive regular expression that you can use is `.*-apb$` if you would want to retrieve all APBs in a registry. See APB Filtering for more details.	N
`black_list`	The list of regular expressions used to define which images names should never be allowed through. See APB Filtering for more details.	N
`images`	The list of images to be used with an OpenShift Container Registry.	N

Production or Development

A production broker configuration is designed to be pointed at a trusted container distribution registry, such as the Red Hat Container Catalog (RHCC):

registry:
  - name: rhcc
    type: rhcc
    url: https://registry.redhat.io
    tag: v3.11
    white_list:
      - ".*-apb$"
  - type: local_openshift
    name: localregistry
    namespaces:
      - openshift
    white_list: []

However, a development broker configuration is primarily used by developers working on the broker. To enable developer settings, set the registry name to dev and the dev_broker field in the broker section to true:

registry:
  name: dev

broker:
  dev_broker: true

Storing Registry Credentials

The broker configuration determines how the broker should read any registry credentials. They can be read from the user and pass values in the registry section, for example:

registry:
  - name: isv
    type: openshift
    url: https://registry.connect.redhat.com
    user: <user>
    pass: <password>

If you want to ensure these credentials are not publicly accessible, the auth_type field in the registry section can be set to the secret or file type. The secret type configures a registry to use a secret from the broker’s namespace, while the file type configures a registry to use a secret that has been mounted as a volume.

To use the secret or file type:

The associated secret should have the values username and password defined. When using a secret, you must ensure that the ansible-service-broker namespace exists, as this is where the secret will be read from.

For example, create a reg-creds.yaml file:
```
$ cat reg-creds.yaml
---
username: <user_name>
password: <password>
```

Create a secret from this file in the ansible-service-broker namespace:

$ oc create secret generic \
    registry-credentials-secret \
    --from-file reg-creds.yaml \
    -n ansible-service-broker

Choose whether you want to use the secret or file type:

To use the secret type:

In the broker configuration, set auth_type to secret and auth_name to the name of the secret:

registry:
  - name: isv
    type: openshift
    url: https://registry.connect.redhat.com
    auth_type: secret
    auth_name: registry-credentials-secret

Set the namespace where the secret is located:

openshift:
  namespace: ansible-service-broker

To use the file type:

Edit the asb deployment configuration to mount your file into /tmp/registry-credentials/reg-creds.yaml:

$ oc edit dc/asb -n ansible-service-broker

In the containers.volumeMounts section, add:

volumeMounts:
  - mountPath: /tmp/registry-credentials
    name: reg-auth

In the volumes section, add:

    volumes:
      - name: reg-auth
        secret:
          defaultMode: 420
          secretName: registry-credentials-secret

In the broker configuration, set auth_type to file and auth_type to the location of the file:

registry:
  - name: isv
    type: openshift
    url: https://registry.connect.redhat.com
    auth_type: file
    auth_name: /tmp/registry-credentials/reg-creds.yaml

APB Filtering

APBs can be filtered out by their image name using a combination of the white_list or black_list parameters, set on a registry basis inside the broker’s configuration.

Both are optional lists of regular expressions that will be run over the total set of discovered APBs for a given registry to determine matches.

Table 2. APB Filter Behavior
Present	Allowed	Blocked
Only whitelist	Matches a regex in list.	Any APB that does not match.
Only blacklist	All APBs that do not match.	APBs that match a regex in list.
Both present	Matches regex in whitelist but not in blacklist.	APBs that match a regex in blacklist.
None	No APBs from the registry.	All APBs from that registry.

For example:

Whitelist Only

white_list:
  - "foo.*-apb$"
  - "^my-apb$"

Anything matching on foo.*-apb$ and only my-apb will be allowed through in this case. All other APBs will be rejected.

Blacklist Only

black_list:
  - "bar.*-apb$"
  - "^foobar-apb$"

Anything matching on bar.*-apb$ and only foobar-apb will be blocked in this case. All other APBs will be allowed through.

Whitelist and Blacklist

white_list:
  - "foo.*-apb$"
  - "^my-apb$"
black_list:
  - "^foo-rootkit-apb$"

Here, foo-rootkit-apb is specifically blocked by the blacklist despite its match in the whitelist because the whitelist match is overridden.

Otherwise, only those matching on foo.*-apb$ and my-apb will be allowed through.

Example Broker Configuration registry Section:

registry:
  - type: dockerhub
    name: dockerhub
    url: https://registry.hub.docker.com
    user: <user>
    pass: <password>
    org: <org>
    white_list:
      - "foo.*-apb$"
      - "^my-apb$"
    black_list:
      - "bar.*-apb$"
      - "^foobar-apb$"

Mock Registry

A mock registry is useful for reading local APB specs. Instead of going out to a registry to search for image specs, this uses a list of local specs. Set the name of the registry to mock to use the mock registry.

registry:
  - name: mock
    type: mock

Dockerhub Registry

The dockerhub type allows you to load APBs from a specific organization in the DockerHub. For example, the ansibleplaybookbundle organization.

registry:
  - name: dockerhub
    type: dockerhub
    org: ansibleplaybookbundle
    user: <user>
    pass: <password>
    white_list:
      - ".*-apb$"

Ansible Galaxy Registry

The galaxy type allows you to use APB roles from Ansible Galaxy. You can also optionally specify an organization.

registry:
  - name: galaxy
    type: galaxy
    # Optional:
    # org: ansibleplaybookbundle
    runner: docker.io/ansibleplaybookbundle/apb-base:latest
    white_list:
      - ".*$"

Local OpenShift Container Registry

Using the local_openshift type will allow you to load APBs from the OpenShift Container Registry that is internal to the OKD cluster. You can configure the namespaces in which you want to look for published APBs.

registry:
  - type: local_openshift
    name: lo
    namespaces:
      - openshift
    white_list:
      - ".*-apb$"

Red Hat Container Catalog Registry

Using the rhcc type will allow you to load APBs that are published to the Red Hat Container Catalog (RHCC) registry.

registry:
  - name: rhcc
    type: rhcc
    url: https://registry.redhat.io
    white_list:
      - ".*-apb$"

Red Hat Partner Connect Registry

Third-party images in the Red Hat Container Catalog are served from the Red Hat Partner Connect Registry at https://registry.connect.redhat.com. The partner_rhcc type allows the broker to be bootstrapped from the Partner Registry to retrieve a list of APBs and load their specs. The Partner Registry requires authentication for pulling images with a valid Red Hat Customer Portal user name and password.

registry:
  - name: partner_reg
    type: partner_rhcc
    url:  https://registry.connect.redhat.com
    user: <registry_user>
    pass: <registry_password>
    white_list:
      - ".*-apb$"

Because the Partner Registry requires authentication, the following manual step is also required to configure the broker to use the Partner Registry URL:

Run the following command on all nodes of a OKD cluster:

# docker --config=/var/lib/origin/.docker \
    login -u <registry_user> -p <registry_password> \
    registry.connect.redhat.com

Helm Chart Registry

Using the helm type allows you to consume Helm Charts from a Helm Chart Repository.

registry:
  - name: stable
    type: helm
    url: "https://kubernetes-charts.storage.googleapis.com"
    runner: "docker.io/automationbroker/helm-runner:latest"
    white_list:
      - ".*"

Many Helm charts in the stable repository are not suitable for use with OKD and will fail with errors if you use them.

API V2 Docker Registry

Using the apiv2 type allows you to consume images from docker registries that implement the Docker Registry HTTP API V2 protocol.

registry:
  - name: <registry_name>
    type: apiv2
    url:  <registry_url>
    user: <registry-user>
    pass: <registry-password>
    white_list:
      - ".*-apb$"

If the registry requires authentication for pulling images, this can be achieved by running the following command on every node in your existing cluster:

$ docker --config=/var/lib/origin/.docker login -u <registry-user> -p <registry-password> <registry_url>

Quay Docker Registry

Using the quay type allows you to load APBs that are published to the CoreOS Quay Registry. If an authentication token is provided, private repositories that the token is configured to access will load. Public repositories in the specified organization do not require a token to load.

registry:
  - name: quay_reg
    type: quay
    url:  https://quay.io
    token: <for_private_repos>
    org: <your_org>
    white_list:
      - ".*-apb$"

If the Quay registry requires authentication for pulling images, this can be achieved by running the following command on every node in your existing cluster:

$ docker --config=/var/lib/origin/.docker login -u <registry-user> -p <registry-password> quay.io

Multiple Registries

You can use more than one registry to separate APBs into logical organizations and be able to manage them from the same broker. The registries must have a unique, non-empty name. If there is no unique name, the service broker will fail to start with an error message alerting you to the problem.

registry:
  - name: dockerhub
    type: dockerhub
    org: ansibleplaybookbundle
    user: <user>
    pass: <password>
    white_list:
      - ".*-apb$"
  - name: rhcc
    type: rhcc
    url: <rhcc_url>
    white_list:
      - ".*-apb$"

Broker Authentication

The broker supports authentication, meaning when connecting to the broker, the caller must supply the Basic Auth or Bearer Auth credentials for each request. Using curl, it is as simple as supplying:

-u <user_name>:<password>

-h "Authorization: bearer <token>

to the command. The service catalog must be configured with a secret containing the user name and password combinations or the bearer token.

Basic Auth

To enable Basic Auth usage, set the following in the broker configuration:

broker:
   ...
   auth:
     - type: basic (1)
       enabled: true (2)

1	The `type` field specifies the type of authentication to use.
2	The `enabled` field allows you to disable a particular authentication type. This keeps you from having to delete the entire section of `auth` just to disable it.

Deployment Template and Secrets

Typically the broker is configured using a configmap in a deployment template. You supply the authentication configuration the same way as in the file configuration.

The following is an example of the deployment template:

auth:
  - type: basic
    enabled: ${ENABLE_BASIC_AUTH}

Another part to Basic Auth is the user name and password used to authenticate against the broker. While the Basic Auth implementation can be backed by different back-end services, the currently supported one is backed by a secret. The secret must be injected into the pod via a volume mount at the /var/run/asb_auth location. This is from where the broker will read the user name and password.

In the deployment template, a secret must be specified. For example:

- apiVersion: v1
  kind: Secret
  metadata:
    name: asb-auth-secret
    namespace: ansible-service-broker
  data:
    username: ${BROKER_USER}
    password: ${BROKER_PASS}

The secret must contain a user name and password. The values must be base64 encoded. The easiest way to generate the values for those entries is to use the echo and base64 commands:

$ echo -n admin | base64 (1)
YWRtaW4=

1	The `-n` option is very important.

This secret must now be injected to the pod via a volume mount. This is configured in the deployment template as well:

spec:
  serviceAccount: asb
  containers:
  - image: ${BROKER_IMAGE}
    name: asb
    imagePullPolicy: IfNotPresent
    volumeMounts:
      ...
      - name: asb-auth-volume
        mountPath: /var/run/asb-auth

Then, in the volumes section, mount the secret:

volumes:
  ...
  - name: asb-auth-volume
    secret:
      secretName: asb-auth-secret

The above will have created a volume mount located at /var/run/asb-auth. This volume will have two files: a user name and password written by the asb-auth-secret secret.

Configuring Service Catalog and Broker Communication

Now that the broker is configured to use Basic Auth, you must tell the service catalog how to communicate with the broker. This is accomplished by the authInfo section of the broker resource.

The following is an example of creating a broker resource in the service catalog. The spec tells the service catalog what URL the broker is listening at. The authInfo tells it what secret to read to get the authentication information.

apiVersion: servicecatalog.k8s.io/v1alpha1
kind: Broker
metadata:
  name: ansible-service-broker
spec:
  url: https://asb-1338-ansible-service-broker.172.17.0.1.nip.io
  authInfo:
    basicAuthSecret:
      namespace: ansible-service-broker
      name: asb-auth-secret

Starting with v0.0.17 of the service catalog, the broker resource configuration changes:

apiVersion: servicecatalog.k8s.io/v1alpha1
kind: ServiceBroker
metadata:
  name: ansible-service-broker
spec:
  url: https://asb-1338-ansible-service-broker.172.17.0.1.nip.io
  authInfo:
    basic:
      secretRef:
        namespace: ansible-service-broker
        name: asb-auth-secret

Bearer Auth

By default, if no authentication is specified the broker will use bearer token authentication (Bearer Auth). Bearer Auth uses delegated authentication from the Kubernetes apiserver library.

The configuration grants access, through Kubernetes RBAC roles and role bindings, to the URL prefix. The broker has added a configuration option cluster_url to specify the url_prefix. This value defaults to ansible-service-broker.

Example Cluster Role

- apiVersion: authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: access-asb-role
  rules:
  - nonResourceURLs: ["/ansible-service-broker", "/ansible-service-broker/*"]
    verbs: ["get", "post", "put", "patch", "delete"]

Deployment Template and Secrets

The following is an example of creating a secret that the service catalog can use. This example assumes that the role, access-asb-role, has been created already. From the deployment template:

- apiVersion: v1
  kind: ServiceAccount
  metadata:
    name: ansibleservicebroker-client
    namespace: ansible-service-broker

- apiVersion: authorization.openshift.io/v1
  kind: ClusterRoleBinding
  metadata:
    name: ansibleservicebroker-client
  subjects:
  - kind: ServiceAccount
    name: ansibleservicebroker-client
    namespace: ansible-service-broker
  roleRef:
    kind: ClusterRole
    name: access-asb-role

- apiVersion: v1
  kind: Secret
  metadata:
    name: ansibleservicebroker-client
    annotations:
      kubernetes.io/service-account.name: ansibleservicebroker-client
  type: kubernetes.io/service-account-token

The above example creates a service account, granting access to access-asb-role and creating a secret for that service accounts token.

Configuring Service Catalog and Broker Communication

Now that the broker is configured to use Bearer Auth tokens, you must tell the service catalog how to communicate with the broker. This is accomplished by the authInfo section of the broker resource.

apiVersion: servicecatalog.k8s.io/v1alpha1
kind: ServiceBroker
metadata:
  name: ansible-service-broker
spec:
  url: https://asb.ansible-service-broker.svc:1338${BROKER_URL_PREFIX}/
  authInfo:
    bearer:
      secretRef:
        kind: Secret

ansible-service-broker

Async bind and unbind is an experimental feature and is not supported or enabled by default. With the absence of async bind, setting launch_apb_on_bind to true can cause the bind action to timeout and will span a retry. The broker will handle this with "409 Conflicts" because it is the same bind request with different parameters.

Secrets Configuration

The secrets section creates associations between secrets in the broker’s namespace and APBs the broker runs. The broker uses these rules to mount secrets into running APBs, allowing the user to use secrets to pass parameters without exposing them to the catalog or users.

The section is a list where each entry has the following structure:

Field Description Required

Field	Description	Required
`title`	The title of the rule. This is just for display and output purposes.	Y
`apb_name`	The name of the APB to associate with the specified secret. This is the fully qualified name (`<registry_name>-<image_name>`).	Y
`secret`	The name of the secret to pull parameters from.	Y

You can download and use the create_broker_secret.py file to create and format this configuration section.

secrets:
- title: Database credentials
  secret: db_creds
  apb_name: dh-rhscl-postgresql-apb

Running Behind a Proxy

When running the OAB inside of a proxied OKD cluster, it is important to understand its core concepts and consider them within the context of a proxy used for external network access.

As an overview, the broker itself runs as a pod within the cluster. It has a requirement for external network access depending on how its registries have been configured.

Registry Adapter Whitelists

The broker’s configured registry adapters must be able to communicate with their external registries in order to bootstrap successfully and load remote APB manifests. These requests can be made via the proxy, however, the proxy must ensure that the required remote hosts are accessible.

Example required whitelisted hosts:

Registry Adapter Type Whitelisted Hosts

Registry Adapter Type	Whitelisted Hosts
`rhcc`	`registry.redhat.io`, `access.redhat.com`
`dockerhub`	`docker.io`

rhcc

registry.redhat.io, access.redhat.com

dockerhub

docker.io

Configuring the Broker Behind a Proxy Using Ansible

If during initial installation you configure your OKD cluster to run behind a proxy (see Configuring Global Proxy Options), when the OAB is deployed it will:

inherit those cluster-wide proxy settings automatically and
generate the required NO_PROXY list, including the cidr fields and serviceNetworkCIDR,

and no further configuration is needed.

Configuring the Broker Behind a Proxy Manually

If your cluster’s global proxy options were not configured during initial installation or prior to the broker being deployed, or if you have modified the global proxy settings, you must manually configure the broker for external access via proxy:

Before attempting to run the OAB behind a proxy, review Working with HTTP Proxies and ensure your cluster is configured accordingly to run behind a proxy.

In particular, the cluster must be configured to not proxy internal cluster requests. This is typically configured with a NO_PROXY setting of:

.cluster.local,.svc,<serviceNetworkCIDR_value>,<master_IP>,<master_domain>,.default

in addition to any other desired NO_PROXY settings. See Configuring NO_PROXY for more details.

Brokers deploying unversioned, or v1 APBs must also add 172.30.0.1 to their NO_PROXY list. APBs prior to v2 extracted their credentials from running APB pods via an exec HTTP request, rather than a secret exchange. Unless you are running a broker with experimental proxy support in a cluster prior to OKD 3.9, you probably do not have to worry about this.

Edit the broker’s DeploymentConfig as a user with cluster-admin privileges:
```
$ oc edit dc/asb -n ansible-service-broker
```
Set the following environment variables:
- HTTP_PROXY
- HTTPS_PROXY
- NO_PROXY
See Setting Proxy Environment Variables in Pods for more information.
After saving any updates, redeploy the OAB’s deployment configuration for the changes to take effect:
```
$ oc rollout latest dc/asb -n ansible-service-broker
```

Setting Proxy Environment Variables in Pods

It is common that APB pods themselves may require external access via proxy as well. If the broker recognizes it has a proxy configuration, it will transparently apply these environment variables to the APB pods that it spawns. As long as the modules used within the APB respect proxy configuration via environment variable, the APB will also use these settings to perform its work.

Finally, it is possible the services spawned by the APB may also require external network access via proxy. The APB must be authored to set these environment variables explicitly if recognizes them in its own execution environment, or the cluster operator must manually modify the required services to inject them into their environments.
