Purpose

This operator is meant to provide a more Kubernetes-native installation method for AWX via an AWX Custom Resource Definition (CRD).

⚠️ The operator is not supported by Red Hat, and is in alpha status. For now, use it at your own risk!

Usage

Basic Install

This Kubernetes Operator is meant to be deployed in your Kubernetes cluster(s) and can manage one or more AWX instances in any namespace.

For testing purposes, the awx-operator can be deployed on a Minikube cluster. Due to different OS and hardware environments, please refer to the official Minikube documentation for further information.

Once Minikube is deployed, check if the node(s) and kube-apiserver communication is working as expected.

$ minikube kubectl -- get nodes

It is not required for kubectl to be separately installed since it comes already wrapped inside minikube. As demonstrated above, simply prefix minikube kubectl -- before kubectl command, i.e. kubectl get nodes would become minikube kubectl -- get nodes

Let's create an alias for easier usage:

$ alias kubectl="minikube kubectl --"

Now you need to deploy AWX Operator into your cluster. Clone this repo and git checkout the latest version from https://github.com/ansible/awx-operator/releases, and then run the following command:

$ export NAMESPACE=my-namespace
$ make deploy
cd config/manager && /home/user/awx-operator/bin/kustomize edit set image controller=quay.io/ansible/awx-operator:0.14.0
/home/user/awx-operator/bin/kustomize build config/default | kubectl apply -f -

configmap/awx-operator-manager-config created
service/awx-operator-controller-manager-metrics-service created
deployment.apps/awx-operator-controller-manager created

Wait a bit and you should have the awx-operator running:

$ kubectl get pods -n $NAMESPACE
NAME                                               READY   STATUS    RESTARTS   AGE
awx-operator-controller-manager-66ccd8f997-rhd4z   2/2     Running   0          11s

So we don't have to keep repeating -n $NAMESPACE, let's set the current namespace for kubectl:

$ kubectl config set-context --current --namespace=$NAMESPACE

Next, create a file named awx-demo.yml with the suggested content below. The metadata.name you provide, will be the name of the resulting AWX deployment.

Note: If you deploy more than one AWX instance to the same namespace, be sure to use unique names.

---
apiVersion: awx.ansible.com/v1beta1
kind: AWX
metadata:
  name: awx-demo
spec:
  service_type: nodeport

Finally, use kubectl to create the awx instance in your cluster:

$ kubectl apply -f awx-demo.yml
awx.awx.ansible.com/awx-demo created

After a few minutes, the new AWX instance will be deployed. You can look at the operator pod logs in order to know where the installation process is at:

$ kubectl logs -f deployments/awx-operator-controller-manager -c awx-manager

After a few seconds, you should see the operator begin to create new resources:

$ kubectl get pods -l "app.kubernetes.io/managed-by=awx-operator"
NAME                        READY   STATUS    RESTARTS   AGE
awx-demo-77d96f88d5-pnhr8   4/4     Running   0          3m24s
awx-demo-postgres-0         1/1     Running   0          3m34s

$ kubectl get svc -l "app.kubernetes.io/managed-by=awx-operator"
NAME                TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
awx-demo-postgres   ClusterIP   None           <none>        5432/TCP       4m4s
awx-demo-service    NodePort    10.109.40.38   <none>        80:31006/TCP   3m56s

Once deployed, the AWX instance will be accessible by running:

$ minikube service awx-demo-service --url -n $NAMESPACE

By default, the admin user is admin and the password is available in the <resourcename>-admin-password secret. To retrieve the admin password, run:

$ kubectl get secret awx-demo-admin-password -o jsonpath="{.data.password}" | base64 --decode
yDL2Cx5Za94g9MvBP6B73nzVLlmfgPjR

You just completed the most basic install of an AWX instance via this operator. Congratulations!!!

Admin user account configuration

There are three variables that are customizable for the admin user account creation.

Name	Description	Default
admin_user	Name of the admin user	admin
admin_email	Email of the admin user	[e-mail]
admin_password_secret	Secret that contains the admin user password	Empty string

⚠️ admin_password_secret must be a Kubernetes secret and not your text clear password.

If admin_password_secret is not provided, the operator will look for a secret named <resourcename>-admin-password for the admin password. If it is not present, the operator will generate a password and create a Secret from it named <resourcename>-admin-password.

To retrieve the admin password, run kubectl get secret <resourcename>-admin-password -o jsonpath="{.data.password}" | base64 --decode

The secret that is expected to be passed should be formatted as follow:

#my-secret-awx-admin.yml
---
apiVersion: v1
kind: Secret
metadata:
  name: <resourcename>-admin-password
  namespace: <target namespace>
stringData:
  password: mysuperlongpassword

$ kubectl apply -f my-secret-awx-admin.yml

Network and TLS Configuration

Service Type

If the service_type is not specified, the ClusterIP service will be used for your AWX Tower service.

The service_type supported options are: ClusterIP, LoadBalancer and NodePort.

The following variables are customizable for any service_type

Name	Description	Default
service_labels	Add custom labels	Empty string

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  service_type: ClusterIP
  service_labels: |
    environment: testing

• LoadBalancer

The following variables are customizable only when service_type=LoadBalancer

Name	Description	Default
loadbalancer_annotations	LoadBalancer annotations	Empty string
loadbalancer_protocol	Protocol to use for Loadbalancer ingress	http
loadbalancer_port	Port used for Loadbalancer ingress	80

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  service_type: LoadBalancer
  loadbalancer_protocol: https
  loadbalancer_port: 443
  loadbalancer_annotations: |
    environment: testing
  service_labels: |
    environment: testing

When setting up a Load Balancer for HTTPS you will be required to set the loadbalancer_port to move the port away from 80.

The HTTPS Load Balancer also uses SSL termination at the Load Balancer level and will offload traffic to AWX over HTTP.

• NodePort

The following variables are customizable only when service_type=NodePort

Name	Description	Default
nodeport_port	Port used for NodePort	30080

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  service_type: NodePort
  nodeport_port: 30080

Ingress Type

By default, the AWX operator is not opinionated and won't force a specific ingress type on you. So, when the ingress_type is not specified, it will default to none and nothing ingress-wise will be created.

The ingress_type supported options are: none, ingress and route. To toggle between these options, you can add the following to your AWX CRD:

• None

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  ingress_type: none

• Generic Ingress Controller

The following variables are customizable when ingress_type=ingress. The ingress type creates an Ingress resource as documented which can be shared with many other Ingress Controllers as listed.

Name	Description	Default
ingress_annotations	Ingress annotations	Empty string
ingress_tls_secret	Secret that contains the TLS information	Empty string
hostname	Define the FQDN	{{ meta.name }}.example.com
ingress_path	Define the ingress path to the service	/
ingress_path_type	Define the type of the path (for LBs)	Prefix

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  ingress_type: ingress
  hostname: awx-demo.example.com
  ingress_annotations: |
    environment: testing

• Route

The following variables are customizable when ingress_type=route

Name	Description	Default
route_host	Common name the route answers for	<instance-name>-<namespace>-<routerCanonicalHostname>
route_tls_termination_mechanism	TLS Termination mechanism (Edge, Passthrough)	Edge
route_tls_secret	Secret that contains the TLS information	Empty string

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  ingress_type: route
  route_host: awx-demo.example.com
  route_tls_termination_mechanism: Passthrough
  route_tls_secret: custom-route-tls-secret-name

Database Configuration

External PostgreSQL Service

In order for the AWX instance to rely on an external database, the Custom Resource needs to know about the connection details. Those connection details should be stored as a secret and either specified as postgres_configuration_secret at the CR spec level, or simply be present on the namespace under the name <resourcename>-postgres-configuration.

The secret should be formatted as follows:

---
apiVersion: v1
kind: Secret
metadata:
  name: <resourcename>-postgres-configuration
  namespace: <target namespace>
stringData:
  host: <external ip or url resolvable by the cluster>
  port: <external port, this usually defaults to 5432>
  database: <desired database name>
  username: <username to connect as>
  password: <password to connect with>
  sslmode: prefer
  type: unmanaged
type: Opaque

Please ensure that the value for the variable "password" is wrapped in quotes if the password contains any special characters.

It is possible to set a specific username, password, port, or database, but still have the database managed by the operator. In this case, when creating the postgres-configuration secret, the type: managed field should be added.

Note: The variable sslmode is valid for external databases only. The allowed values are: prefer, disable, allow, require, verify-ca, verify-full.

Migrating data from an old AWX instance

For instructions on how to migrate from an older version of AWX, see migration.md.

Managed PostgreSQL Service

If you don't have access to an external PostgreSQL service, the AWX operator can deploy one for you along side the AWX instance itself.

The following variables are customizable for the managed PostgreSQL service

Name	Description	Default
postgres_image	Path of the image to pull	postgres:12
postgres_resource_requirements	PostgreSQL container resource requirements	Empty object
postgres_storage_requirements	PostgreSQL container storage requirements	requests: {storage: 8Gi}
postgres_storage_class	PostgreSQL PV storage class	Empty string
postgres_data_path	PostgreSQL data path	/var/lib/postgresql/data/pgdata

Example of customization could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  postgres_resource_requirements:
    requests:
      cpu: 500m
      memory: 2Gi
    limits:
      cpu: 1
      memory: 4Gi
  postgres_storage_requirements:
    requests:
      storage: 8Gi
    limits:
      storage: 50Gi
  postgres_storage_class: fast-ssd

Note: If postgres_storage_class is not defined, Postgres will store it's data on a volume using the default storage class for your cluster.

Advanced Configuration

Deploying a specific version of AWX

There are a few variables that are customizable for awx the image management.

Name	Description
image	Path of the image to pull
image_version	Image version to pull
image_pull_policy	The pull policy to adopt
image_pull_secret	The pull secret to use
ee_images	A list of EEs to register
redis_image	Path of the image to pull
redis_image_version	Image version to pull

Example of customization could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  image: myorg/my-custom-awx
  image_version: latest
  image_pull_policy: Always
  image_pull_secret: pull_secret_name
  ee_images:
    - name: my-custom-awx-ee
      image: myorg/my-custom-awx-ee

Note: The image and image_version are intended for local mirroring scenarios. Please note that using a version of AWX other than the one bundled with the awx-operator is not supported. For the default values, check the main.yml file.

Redis container capabilities

Depending on your kubernetes cluster and settings you might need to grant some capabilities to the redis container so it can start. Set the redis_capabilities option so the capabilities are added in the deployment.

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  redis_capabilities:
    - CHOWN
    - SETUID
    - SETGID

Privileged Tasks

Depending on the type of tasks that you'll be running, you may find that you need the task pod to run as privileged. This can open yourself up to a variety of security concerns, so you should be aware (and verify that you have the privileges) to do this if necessary. In order to toggle this feature, you can add the following to your custom resource:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  task_privileged: true

If you are attempting to do this on an OpenShift cluster, you will need to grant the awx ServiceAccount the privileged SCC, which can be done with:

$ oc adm policy add-scc-to-user privileged -z awx

Again, this is the most relaxed SCC that is provided by OpenShift, so be sure to familiarize yourself with the security concerns that accompany this action.

Containers Resource Requirements

The resource requirements for both, the task and the web containers are configurable - both the lower end (requests) and the upper end (limits).

Name	Description	Default
web_resource_requirements	Web container resource requirements	requests: {cpu: 1000m, memory: 2Gi}
task_resource_requirements	Task container resource requirements	requests: {cpu: 500m, memory: 1Gi}
ee_resource_requirements	EE control plane container resource requirements	requests: {cpu: 500m, memory: 1Gi}

Example of customization could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  web_resource_requirements:
    requests:
      cpu: 1000m
      memory: 2Gi
    limits:
      cpu: 2000m
      memory: 4Gi
  task_resource_requirements:
    requests:
      cpu: 500m
      memory: 1Gi
    limits:
      cpu: 1000m
      memory: 2Gi
  ee_resource_requirements:
    requests:
      cpu: 500m
      memory: 1Gi
    limits:
      cpu: 1000m
      memory: 2Gi

Assigning AWX pods to specific nodes

You can constrain the AWX pods created by the operator to run on a certain subset of nodes. node_selector and postgres_selector constrains the AWX pods to run only on the nodes that match all the specified key/value pairs. tolerations and postgres_tolerations allow the AWX pods to be scheduled onto nodes with matching taints.

Name	Description	Default
postgres_image	Path of the image to pull	12
postgres_image_version	Image version to pull	12
node_selector	AWX pods' nodeSelector	''
tolerations	AWX pods' tolerations	''
postgres_selector	Postgres pods' nodeSelector	''
postgres_tolerations	Postgres pods' tolerations	''

Example of customization could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  node_selector: |
    disktype: ssd
    kubernetes.io/arch: amd64
    kubernetes.io/os: linux
  tolerations: |
    - key: "dedicated"
      operator: "Equal"
      value: "AWX"
      effect: "NoSchedule"
  postgres_selector: |
    disktype: ssd
    kubernetes.io/arch: amd64
    kubernetes.io/os: linux
  postgres_tolerations: |
    - key: "dedicated"
      operator: "Equal"
      value: "AWX"
      effect: "NoSchedule"

Trusting a Custom Certificate Authority

In cases which you need to trust a custom Certificate Authority, there are few variables you can customize for the awx-operator.

Trusting a custom Certificate Authority allows the AWX to access network services configured with SSL certificates issued locally, such as cloning a project from from an internal Git server via HTTPS. It is common for these scenarios, experiencing the error unable to verify the first certificate.

Name	Description	Default
ldap_cacert_secret	LDAP Certificate Authority secret name	''
bundle_cacert_secret	Certificate Authority secret name	''

Please note the awx-operator will look for the data field ldap-ca.crt in the specified secret when using the ldap_cacert_secret, whereas the data field bundle-ca.crt is required for bundle_cacert_secret parameter.

Example of customization could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  ldap_cacert_secret: <resourcename>-custom-certs
  bundle_cacert_secret: <resourcename>-custom-certs

To create the secret, you can use the command below:

# kubectl create secret generic <resourcename>-custom-certs \
    --from-file=ldap-ca.crt=<PATH/TO/YOUR/CA/PEM/FILE>  \
    --from-file=bundle-ca.crt=<PATH/TO/YOUR/CA/PEM/FILE>

Persisting Projects Directory

In cases which you want to persist the /var/lib/projects directory, there are few variables that are customizable for the awx-operator.

Name	Description	Default
projects_persistence	Whether or not the /var/lib/projects directory will be persistent	false
projects_storage_class	Define the PersistentVolume storage class	''
projects_storage_size	Define the PersistentVolume size	8Gi
projects_storage_access_mode	Define the PersistentVolume access mode	ReadWriteMany
projects_existing_claim	Define an existing PersistentVolumeClaim to use (cannot be combined with projects_storage_*)	''

Example of customization when the awx-operator automatically handles the persistent volume could be:

# ansible/instantiate-awx-deployment.yml
---
spec:
  ...
  projects_persistence: true
  projects_storage_class: rook-ceph
  projects_storage_size: 20Gi

Custom Volume and Volume Mount Options

In a scenario where custom volumes and volume mounts are required to either overwrite defaults or mount configuration files.

Name	Description	Default
extra_volumes	Specify extra volumes to add to the application pod	''
web_extra_volume_mounts	Specify volume mounts to be added to Web container	''
task_extra_volume_mounts	Specify volume mounts to be added to Task container	''
ee_extra_volume_mounts	Specify volume mounts to be added to Execution container	''
init_container_extra_volume_mounts	Specify volume mounts to be added to Init container	''
init_container_extra_commands	Specify additional commands for Init container	''

⚠️ The ee_extra_volume_mounts and extra_volumes will only take effect to the globally available Execution Environments. For custom ee, please customize the Pod spec.

          mountPath: /shared

⚠️ Volume and VolumeMount names cannot contain underscores(_)

Default execution environments from private registries

In order to register default execution environments from private registries, the Custom Resource needs to know about the pull credentials. Those credentials should be stored as a secret and either specified as ee_pull_credentials_secret at the CR spec level, or simply be present on the namespace under the name <resourcename>-ee-pull-credentials . Instance initialization will register a Container registry type credential on the deployed instance and assign it to the registered default execution environments.

The secret should be formated as follows:

---
apiVersion: v1
kind: Secret
metadata:
  name: <resourcename>-ee-pull-credentials
  namespace: <target namespace>
stringData:
  url: <registry url. i.e. quay.io>
  username: <username to connect as>
  password: <password to connect with>
  ssl_verify: <Optional attribute. Whether verify ssl connection or not. Accepted values "True" (default), "False" >
type: Opaque

Control plane ee from private registry

The images listed in "ee_images" will be added as globally available Execution Environments. The "control_plane_ee_image" will be used to run project updates. In order to use a private image for any of these you'll need to use image_pull_secret to provide a k8s pull secret to access it. Currently the same secret is used for any of these images supplied at install time.

You can create image_pull_secret

kubectl create secret <resoucename>-cp-pull-credentials regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>

If you need more control (for example, to set a namespace or a label on the new secret) then you can customise the Secret before storing it

Example spec file extra-config

---
apiVersion: v1
kind: Secret
metadata:
  name: <resoucename>-cp-pull-credentials
  namespace: <target namespace>
data:
  .dockerconfigjson: <base64 docker config>
type: kubernetes.io/dockerconfigjson

Exporting Environment Variables to Containers

If you need to export custom environment variables to your containers.

Name	Description	Default
task_extra_env	Environment variables to be added to Task container	''
web_extra_env	Environment variables to be added to Web container	''
ee_extra_env	Environment variables to be added to EE container	''

⚠️ The ee_extra_env will only take effect to the globally available Execution Environments. For custom ee, please customize the Pod spec.

Example configuration of environment variables

# ansible/instantiate-awx-deployment.yml
  spec:
  ...
    task_extra_env: |
      - name: MYCUSTOMVAR
        value: foo
    web_extra_env: |
      - name: MYCUSTOMVAR
        value: foo
    ee_extra_env: |
      - name: MYCUSTOMVAR
        value: foo

Extra Settings

Withextra_settings, you can pass multiple custom settings via the awx-operator. The parameter extra_settings will be appended to the /etc/tower/settings.py and can be an alternative to the extra_volumes parameter.

Name	Description	Default
extra_settings	Extra settings	''

Example configuration of extra_settings parameter

# ansible/instantiate-awx-deployment.yml
  spec:
  ...
    extra_settings:
      - setting: MAX_PAGE_SIZE
        value: "500"

      - setting: AUTH_LDAP_BIND_DN
        value: "cn=admin,dc=example,dc=com"

Service Account

If you need to modify some ServiceAccount proprieties

Name	Description	Default
service_account_annotations	Annotations to the ServiceAccount	''

Example configuration of environment variables

  # ansible/instantiate-awx-deployment.yml
  ---
  spec:
  ...
    service_account_annotations: |
      eks.amazonaws.com/role-arn: arn:aws:iam::<ACCOUNT_ID>:role/<IAM_ROLE_NAME>

Uninstall

To uninstall an AWX deployment instance, you basically need to remove the AWX kind related to that instance. For example, to delete an AWX instance named awx-demo, you would do:

$ kubectl delete awx awx-demo
awx.awx.ansible.com "awx-demo" deleted

Deleting an AWX instance will remove all related deployments and statefulsets, however, persistent volumes and secrets will remain. To enforce secrets also getting removed, you can use garbage_collect_secrets: true.

Upgrading

To upgrade AWX, it is recommended to upgrade the awx-operator to the version that maps to the desired version of AWX. To find the version of AWX that will be installed by the awx-operator by default, check the version specified in the image_version variable in roles/installer/defaults/main.yml for that particular release.

Apply the awx-operator.yml for that release to upgrade the operator, and in turn also upgrade your AWX deployment.

v0.14.0

Cluster-scope to Namespace-scope considerations

Starting with awx-operator 0.14.0, AWX can only be deployed in the namespace that the operator exists in. This is called a namespace-scoped operator. If you are upgrading from an earlier version, you will want to delete your existing awx-operator service account, role and role binding.

Project is now based on v1.x of the operator-sdk project

Starting with awx-operator 0.14.0, the project is now based on operator-sdk 1.x. You may need to manually delete your old operator Deployment to avoid issues.

Release Process

The first step is to create a draft release. Typically this will happen in the Stage Release workflow for AWX and you dont need to do it as a separate step.

If you need to do an independent release of the operator, you can run the Stage Release in the awx-operator repo. Both of these workflows will run smoke tests, so there is no need to do this manually.

After the draft release is created, publish it and the Promote AWX Operator image will run, publishing the image to Quay.
