# 📚 AWX on Single Node K3s



An example implementation of AWX on single node K3s using AWX Operator, with easy-to-use simplified configuration with ownership of data and passwords.



- Accessible over HTTPS from remote host

- All data will be stored under `/data`

- Fixed (configurable) passwords for AWX and PostgreSQL

- Fixed (configurable) versions of AWX



**If you want to view the guide for the specific version of AWX Operator, switch the page to the desired tag instead of the `main` branch.**

## 📝 Environment



- Tested on:

  - CentOS Stream 9 (Minimal)

  - K3s v1.29.6+k3s2

- Products that will be deployed:

  - AWX Operator 2.19.1

  - AWX 24.6.1

  - PostgreSQL 15

- [README.md on ansible/awx-operator](https://github.com/ansible/awx-operator/blob/2.19.1/README.md) @2.19.1



## 📝 Requirements



- **Computing resources**

  - **2 CPUs minimum**.

    - Both **AMD64** (x86_64) with x86-64-v2 support, and **ARM64**  (aarch64) are supported.

  - **4 GiB RAM minimum**.

  - It's recommended to add more CPUs and RAM (like 4 CPUs and 8 GiB RAM or more) to avoid performance issue and job scheduling issue.

  - The files in this repository are configured to ignore resource requirements which specified by AWX Operator by default.

- **Storage resources**

  - At least **10 GiB for `/var/lib/rancher`** and **10 GiB for `/data`** are safe for fresh install.

    - `/var/lib/rancher` will be created and consumed by K3s and related data like container images and overlayfs.

    - `/data` will be created in this guide and used to store AWX-related databases and files.

  - **Both will be grown during lifetime** and **actual consumption highly depends on your environment and your use case**, so you should to pay attention to the consumption and add more capacity if required.



## 📝 Deployment Instruction



### ✅ Prepare CentOS Stream 9 host



Disable firewalld and nm-cloud-setup if enabled. This is [recommended by K3s](https://docs.k3s.io/installation/requirements?os=rhel#operating-systems).



```bash

# Disable firewalld

sudo systemctl disable firewalld --now



# Disable nm-cloud-setup if exists and enabled

sudo systemctl disable nm-cloud-setup.service nm-cloud-setup.timer

sudo reboot

```



Install the required packages to deploy AWX Operator and AWX.



```bash

sudo dnf install -y git curl

```



### ✅ Install K3s



Install a specific version of K3s with `--write-kubeconfig-mode 644` to make the config file (`/etc/rancher/k3s/k3s.yaml`) readable by non-root users.



```bash

curl -sfL https://get.k3s.io | INSTALL_K3S_VERSION=v1.29.6+k3s2 sh -s - --write-kubeconfig-mode 644

```



### ✅ Install AWX Operator



Clone this repository and change directory.



If you want to use files suitable for a specific version of AWX Operator, [refer to tags in this repository](https://github.com/kurokobo/awx-on-k3s/tags) and specify the desired tag in `git checkout`. Especially for `0.13.0` or earlier versions of AWX Operator, refer to [📝Tips: Deploy older version of AWX Operator](tips/deploy-older-operator.md).



```bash

cd ~

git clone https://github.com/kurokobo/awx-on-k3s.git

cd awx-on-k3s

git checkout 2.19.1

```



Then invoke `kubectl apply -k operator` to deploy AWX Operator.



```bash

kubectl apply -k operator

```



The AWX Operator will be deployed to the namespace `awx`.



```bash

$ kubectl -n awx get all

NAME                                                   READY   STATUS    RESTARTS   AGE

pod/awx-operator-controller-manager-68d787cfbd-kjfg7   2/2     Running   0          16s



NAME                                                      TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE

NAME                                                         DESIRED   CURRENT   READY   AGE

replicaset.apps/awx-operator-controller-manager-68d787cfbd   1         1         1       16s

```



### ✅ Prepare required files to deploy AWX



Generate a Self-Signed certificate. Note that an IP address can't be specified. If you want to use a certificate from a public ACME CA such as Let's Encrypt or ZeroSSL instead of a Self-Signed certificate, follow the guide on [📁 **Use SSL Certificate from Public ACME CA**](acme) first and come back to this step when done.



```bash

AWX_HOST="awx.example.com"

openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -out ./base/tls.crt -keyout ./base/tls.key -subj "/CN=${AWX_HOST}/O=${AWX_HOST}" -addext "subjectAltName = DNS:${AWX_HOST}"

```



Modify `hostname` in `base/awx.yaml`.



```yaml

...

spec:

  ...

  ingress_type: ingress

  ingress_hosts:

    - hostname: awx.example.com   👈👈👈

      tls_secret: awx-secret-tls

...

```



Modify the two `password` entries in `base/kustomization.yaml`. Note that the `password` under `awx-postgres-configuration` should not contain single or double quotes (`'`, `"`) or backslashes (`\`) to avoid any issues during deployment, backup or restoration.



```yaml

...

  - name: awx-postgres-configuration

    type: Opaque

    literals:

      - host=awx-postgres-15

      - port=5432

      - database=awx

      - username=awx

      - password=Ansible123!   👈👈👈

      - type=managed



  - name: awx-admin-password

    type: Opaque

    literals:

      - password=Ansible123!   👈👈👈

...

```



Prepare directories for Persistent Volumes defined in `base/pv.yaml`. These directories will be used to store your databases and project files. Note that the size of the PVs and PVCs are specified in some of the files in this repository, but since their backends are `hostPath`, its value is just like a label and there is no actual capacity limitation.



```bash

sudo mkdir -p /data/postgres-15

sudo mkdir -p /data/projects

sudo chown 1000:0 /data/projects

```



### ✅ Deploy AWX



Deploy AWX, this takes few minutes to complete.



```bash

kubectl apply -k base

```



To monitor the progress of the deployment, check the logs of `deployments/awx-operator-controller-manager`:



```bash

kubectl -n awx logs -f deployments/awx-operator-controller-manager

```



If the deployment completes successfully, the logs end with:



```txt

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

...

----- Ansible Task Status Event StdOut (awx.ansible.com/v1beta1, Kind=AWX, awx/awx) -----

PLAY RECAP *********************************************************************

localhost                  : ok=90   changed=0    unreachable=0    failed=0    skipped=83   rescued=0    ignored=1

```



The required objects should now have been deployed next to AWX Operator in the `awx` namespace.



```bash

$ kubectl -n awx get awx,all,ingress,secrets

```



Now your AWX is available at `https://awx.example.com/` or the hostname you specified.



Note that you have to access via the hostname that you specified in `base/awx.yaml`, instead of by IP address, since this guide uses Ingress. So you should configure your DNS or `hosts` file on your client where the browser is running.



At this point, AWX can be accessed via HTTP as well as HTTPS. If you want to force users to use HTTPS, see [📝Tips: Enable HTTP Strict Transport Security (HSTS)](tips/enable-hsts.md).



## 📝 Back up and Restore AWX using AWX Operator



The AWX Operator `0.10.0` or later has the ability to back up and restore AWX in easy way.



Refer [📁 **Back up AWX using AWX Operator**](backup) and [📁 **Restore AWX using AWX Operator**](restore) for details.
