#atlantis - January 2019

I’ll be giving a live demo of Atlantis

nice slides

Lots of content on your slides. Will it be an hour talk?

last I did it was ~30 minutes + 30 minute q&a

also, these are the old slides

going to revamp them before the conf

Good luck with this talk. It is great to share Atlantis with the community in any way. (I am about to be involved in getting it up and running in Azure… omg)

Hey, im always curious about Atlantis, kind of would like to use it, but we prefer to apply on merge.
For the ones doing apply on PR, how do you work with it and lets say, ECS.
We have our ECS service defined in terraform for the time being (yeah not the best I know, but this could be a DB change or something else) and if we applied on PR, the new container or service that should use this will not be deployed yet, unless you also build the container on PR.
How do you handle that?

@Gonzalo Peci by default we deploy a standard backing image with ECS

and then use an out of band CI/CD to deploy the actual app we want

Yeah, the docker part was just an example

but if you had certain DB change for example, it would be the same

The container one was just an example because it makes clear the "problem" i see

but there might be other changes that should be insync with that is deployed

Too bad Atlantis closed the PR for apply on merge, because that workflow would be sweet, atlantis saves plan from PR, which was approved in line, then on merge, it applies that plan

hey hey

which atlantis repo should I be looking at to run atlantis in conjunction with the geodesic ref arch?

I mean I see ECS https://github.com/cloudposse/terraform-aws-ecs-atlantis & ECS fargate https://github.com/cloudposse/geodesic-aws-atlantis

wait and a helm chart?

so ooooooo

I don't recommend running atlantis in kubernetes

we started down that path and support it

yea I agree

I want atlantis to be managing my k8s clusters

But just remember, then you have a pod that someone can kubectl exec into with admin

avoid the inception trap

So we have a nice e2e working story with ECS Fargate

im alright with that for now

later I might consider a locked down k8s or soemthing

@joshmyers finished updating our example here:

We merged that this morning

something less AWS specific

unfortunately, not documented

All the ECS/Atlatnis stuff is demonstrated here: https://github.com/cloudposse/terraform-root-modules/tree/master/aws/ecs

haha you know I like my docs in the form of code

Currently, we don't have an alpine package for atlantis (our fork)

So we do this: https://github.com/cloudposse/testing.cloudposse.co/blob/master/Dockerfile#L71-L72

I should probably give you a demo of what the workflow looks like using Atlantis

B/c the docker multi-stage isn't ideally suited for it.

Yeah, it took quite a bit of plumbing to get to work in this workflow

so I will need to get atlantis in place asap

have on-boarded 8 core team members to our version of geodesic + ref arch

pipelines are next up

and a few others

I can give you the low down so you can get started

won't take long to deploy
