Install AWX Community Edition (RPM)

Now updated to the newest release of AWX (python3 and PostgreSQL 10), please be adviced that this has not been firmly tested, yet..

Follow updates and other info at: https://twitter.com/martinjuhl and https://www.linkedin.com/in/martin-juhl-9b71b25/

Caveats/TODO List

  • Firewall rules has still not been created, so you'll have to make your own or disable the firewall...
  • Backup/Restore scripts
  • Fix Migrations/upgrades so that they will work everytime.. see bottom for more description..

Please submit issues here: https://github.com/MrMEEE/awx-build/issues

PreReqs

Disk requirements

AWX is primarily resident in /opt/awx and /opt/rh/rh-python36, where it takes up around 500MB...

It's works is done in tmp and /var/lib/awx.. but shouldn't take up much space...

I would say that a server with 10GB of space should be more than enough to start with.. Of course this depends on your playbooks..

1: Small workarounds needed

2: "awx-manage makemigrations" needs to be run with "--merge"

Upgrading to newest version (not guaranteed to work)

yum update
sudo -u awx scl enable rh-postgresql10 rh-python36 "awx-manage makemigrations"
sudo -u awx scl enable rh-postgresql10 rh-python36 "awx-manage migrate"

Broken Upgrade Paths

Confirmed Breaking Upgrade paths:

  • 1.0.5.31 -> 1.0.5.32

Here you need to get creative.

Got an answer from the AWX Team:

"Upgrades between AWX versions are not expected to work. However, we have recently added an import/export capability to tower-cli/awx-cli, which allows you to export your job templates and other objects (not including credential secrets) to a JSON file, which you can then re-import to a freshly installed 1.0.6."

They are referring to the awx-cli tool from their separate repo.. also, the awx-manage tool have a dumpdata/loaddata tool...

I'm going to see if I can do a workaround for upgrades.

Upgrade Method Using Export/Import Utility

For the guys that really want to push their luck :)... Something like this will probably work.

You have to install awx-cli in advance, available in the repo:

yum install ansible-tower-cli

As far as I can see.. this is missing when using the awx-cli export/import:

  • Users (export is blank), and therefore user permissions isn't set
  • Log/History is not exported (not high priority in the short run)
  • Inventory Groups (custom created groups fails for me, going from 1.0.5.31->1.0.6.1
  • Credential passwords (there should be an option to include them)
  • LDAP/Auth config (is just not included)

Create a backup of AWX data

awx-cli receive --organization all --team all --credential_type all --credential all --notification_template all --user all --inventory_script all --inventory all --project all --job_template all --workflow all > alldata

Stop all services, re-create the database

systemctl stop awx-celery-worker awx-cbreceiver awx-celery-beat awx-channels-worker awx-daphne awx-web
su - postgres -c "dropdb awx"
su - postgres -c "createdb -O awx awx"

Migrate AWX data into the new database

sudo -u awx /opt/awx/bin/awx-manage migrate

Re-create the admin user, provision the instance and queues

echo "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'root@localhost', 'test')" | sudo -u awx /opt/awx/bin/awx-manage shell
sudo -u awx /opt/awx/bin/awx-manage provision_instance --hostname=$(hostname)
sudo -u awx /opt/awx/bin/awx-manage register_queue --queuename=tower --hostnames=$(hostname)

Restore AWX data from the file (alldata)

awx-cli send alldata

High availability setup

Has been reported to work here
