awx ansible on rhel

  • laurent 

As you probably read we did opensource ansible tower

https://github.com/ansible/awx . This was a big and necessary step to follow the red hat way of being truly opensource. Thanks to Jeff Geerling we also have a role https://galaxy.ansible.com/geerlingguy/awx/ to install awx.

To install AWX on RHEL (remember this is not supported by GSS) you need to do the following:

Step1: register your host with Red Hat

[root@host141 ~]# subscription-manager register

Step2: now add the needed channels

[root@host141 ~]# subscription manager attach --pool YOURPOOLFORRHEL

Step3: enable the repos extras and optional

[root@host141 ~]# subscription-manager repos --disable=*
[root@host141 ~]# subscription-manager repos --enable=rhel-7-server-rpms --enable=rhel-7-server-extras-rpms --enable=rhel-7-server-optional-rpms

Step4: to be able to run the build correctly you will have to do the following

[root@host141 ~]# mkdir -p /etc/docker

Step 5: add the following file. Without that you build will fail complaining that you cannot connect to github

[root@host141 ~]# cat << EOF > /etc/docker/daemon.json 
{
    "dns": ["8.8.8.8"]
}
EOF

Step 6: install ansible

[root@host141 ~]# yum install -y ansible

Step 7: install all the necessary roles

[root@host141 ~]# cat << EOF > roles-for-awx.sh
ansible-galaxy install  geerlingguy.git
ansible-galaxy install geerlingguy.ansible
ansible-galaxy install  geerlingguy.docker
ansible-galaxy install  geerlingguy.pip
ansible-galaxy install  geerlingguy.nodejs
ansible-galaxy install geerlingguy.repo-epel
ansible-galaxy install geerlingguy.awx
EOF

chmod +x roles-for-awx.sh

Step 8: install the roles:

[root@host141 ~]# ./roles-for-awx.sh

Step 9: create the inventory add your host

[root@host141 ~]# mkdir inventory
[root@host141 ~]# touch hosts inventory/
[root@host141 ~]# echo '192.168.1.55' > inventory/hosts

Step 10: create the play to install awx

[root@host141 ~]# echo << EOF > install.yml
---
- hosts: all
  become: yes

  vars:
    nodejs_version: "6.x"
    pip_install_packages:
      - name: docker-py

  pre_tasks:
    - name: Update apt cache.
      apt: update_cache=yes cache_valid_time=600
      when: ansible_os_family == 'Debian'
      changed_when: false

  roles:
    - name: geerlingguy.repo-epel
      when: ansible_os_family == "RedHat"
    - geerlingguy.git
    - geerlingguy.ansible
    - geerlingguy.docker
    - geerlingguy.pip
    - geerlingguy.nodejs
    - geerlingguy.awx
EOF

Step 11: run the playbook

[root@host141 ~]# ansible-playbook -i inventory install.yml -vv

Step 12: If the install is successful you will see the following

[root@host141 ~]# docker ps
CONTAINER ID        IMAGE                COMMAND                  CREATED             STATUS              PORTS                                NAMES

Step 13: It will take a while until the instance comes up. You can check it like this

[root@host141 awx]# docker logs -f awx_task
