- This week's video is about building an Ansible Tower Cluster with the newly released Ansible Tower 3.1.1. Don't be afraid: the actual installation is sped up and takes less than a minute ;)

+Open Site Solutions OSS Great to read the video helped you!
Great Video!
+Colin McCarthy thanks! Glad you found it useful.
Thanks Maxim for this great video. It helped me build the Ansible Tower Cluster. Can you please make a video on Building an Ansible Tower HA with multi master PostgreSQL so that my Ansible tower doesn't fail on failure of primary PostgreSQL database server. Including PostgreSQL replication with Active-Active PostgreSQL or Active -passive PostgreSQL. Thanks
That's actually a tricky one. I've never done database HA. I'll put it on my backlog, but can't give you a timeline.
Great video. Thank you. Do you think you could make a video on how to setup a cluster with a load balancer, so user could just go to one address (like tower.domain.com), and get sent to one of the 3 servers?
Just answered another question about this. (Sorry this took so long, I never got notifications for these replies! Fixed that now!)
If you are still reading this: I've never looked into putting an LB in front of a Tower cluster. At first glance, it does seem to be possible though, so I'll take a look. Might want to check out deploying Tower on OpenShift as well for even more scaling options!
What type of load balancer is best to use for load balance the jobs?
Jobs do not get load balanced through a load balancer. What you could do is set up a load balancer in front of the Tower UI, but that's a different use case, I guess.
Newer version of Tower (3.4+) support job slicing, which is like load balancing of jobs, and that feature does not need a load balancer at all. Check the Tower docs. If you can't find it, let me know and I'll send you some links :)
Does ansible tower support sticky/persistent sessions? It's a more viable solution to throw up a load balancer in front of your a-a.
Sorry for the late reply: I didn't get notifications of these up until now :/
I'm not sure. I've never tried. I do think most deployments are like I described. If you deploy Tower on OpenShift, you get another, even more scalable Tower design. I'll spend some time on that in the future.
Man, what task failed during setup? And how long it took you to fix that?
There's an iptables firewall task that fails on machines that run firewalld, iirc. Doesn't need fixing: there are dedicated tasks for firewalld, and they complete fine. The one failed task is cosmetic. Probably should have mentioned that :)
You have a keen eye, sir ;)
Can you do for ansibleawx installation on k8s cluster
RUclips doesn't seem to give me notifications for new comments anymore, so.sorry for the late reply.
Interesting idea. Will look into it.
I've put deploying Ansible Tower on OpenShift on my list for now, does that fit your request?
What does /api/v1/ping looks like?
I already tore down this cluster again. I'm not sure what you are looking for. Next time I build one, what do you think I should check for in that output?
