@Sebastian Nemeth how about this?
With a couple of tweaks the WSL (Windows Subsystem for Linux, also known as Bash for Windows) can be used with Docker for Windows.
@Erik Osterman (Cloud Posse) I actually followed this guide to set up docker on WSL and it’s a good reference for you to include in your documentation. I have the path set up as per this guide, so that mounting from /c works fine, but our problem is with /home/username.
I have the strangest situation using Docker on WSL (Windows Subsystem for Linux, Ubuntu 16.04). I’m trying to bind mount /home/username (or just $HOME for convenience) as a volume in a container, and

That’s v. interesting.

Awesome! Thanks… we shall incorporate it
@rohit.verma @Max Moon what are your thoughts on moving helmfiles to a separate repo that can be rev’d separately?
Especially since they can now be decomposed to helmfile.d
most likely I would recommend to use it in root-modules
you can actually rename terraform-root-modules to root-modules
please see my repo, i am kindly doing the same
I’ve struggled with mixing the technologies
Charts are separate
Terraform is separate
Seems like helmfiles should be separate
I work on principal of environment, what are the things which aggregately define my environment will come in same repo in the end
doesn’t matter from where it came
Environments are to me the account repos
we can create a new repo and in docker file add the same syntax
Those tie everything together
yes, environmet = account repo
Packages come from packages
Terraform code from root modules
Charts from charts.
Seems like clean separations no?
I agree completely with you
Cool I’ll track this in a separate issue
what i meant is that in dockerfile Assume we have
COPY --from=terraform-root-modules /aws/tfstate-backend/ /conf/tfstate-backend/ COPY --from=charts /aws/basic /conf/basic (includes, dashboard etc...) COPY --from=charts /aws/monitor /conf/monitor (includes, kube-prometheus etc...) COPY --from=services /aws/services /conf/services
But when we are overriding anything e.g monitor, we would be overriding in dev.niki.ai only
As I explained earlier, to view the root-modules charts in my ide, i end up copying all to my code only. On first setup I did copy from terraform root, but then I moved it to my repo
Ok, makes sense. I recommend your approach as well.
also one thing I wanted to ask since started using helmfile, how can we sync only updated services. Helmfile sync always update all the services
doesn’t it use any hashing technique for a release
We use selectors extensively
Doesn’t that mitigate it?
Basically, I never call sync without a selector
I treat helmfile like a package manager
There also helmfile diff
I know @Daren loves this
I saw you recommended upsert
Oh yea, on that discussion
No response yet though, right?
This idea comes from the kubectl apply -f –prune where kubectl deletes any resources that aren't referenced. Helmfile should have an option for the sync command that checks what helm charts ar…
I will start migrating things to helmfile.d, than will hash of individual file
will share once done
@alebabai is converting them
Pr is undergoing testing
i need to do for our micro-services
is there a utility (shell 1 liners for this)? or you are doing manually
i think yq on name array and echo in name files should do
Yea, it’s called vim ;)
Oh, you mean for the testing?
That could work, but lots of envs in chamber also need to be set
why we need to worry about chamber when migrating from helmfile to helmfile.d
Oh we just use that to store the envs used by the files
Migrating is actually risky
Let me explain
helm —set does automatic type casting
If it sees a string that looks like a number it makes it an int
If it sees a Boolean sting it makes it a Boolean
So when converting to inline values it’s critical to maintain cast
Errors won’t be obvious
Subtle feature of charts might get accidentally disable if true is a string
While certain annotations require values to numbers to be strings
So the helmfile ‘set’ declaration just called —set
That’s why we care

That’s awesome! Thanks for sharing
@Erik Osterman (Cloud Posse) is there any update on when this or similar solution will be rolled into geodesic?
We’d really rather just reference geodesic at the trunk than have to fork/build/push our own image
Was hoping today, but still not happy with the current PR solution. It appears that depending on the method of installation or version of WSL that the home path varies.
Ahhh that’s true. I’ve uninstalled WSL and reinstalled it on my system, so my home path might not even be the default one with current Windows.
what $HOME path now is built dynamically (search wsl dir on windows, getting windows and linux users names) why By default $HOME refers on /usr/local/bin, but in case with WSL, docker installed…
Here’s the current progress. A few more minor nitpicks to be solved and then we’ll merge.
We cannot test your path, however, so might not work
@rohit.verma anyone on your team using Geodesic on WSL?
Learn more about how the Windows Subsystem for Linux works.
Hey guys - the cold start docs describe setting up aws-vault on your local machine, but it’s also available in the geodesic container. Does it have to be set up in both places, or does geodesic mount ~/.aws/config or something? Or is it best practice to only use aws-vault from geodesic?
@Sebastian Nemeth that is correct, geodesic mounts ~/.aws/config: https://github.com/cloudposse/geodesic/blob/a430b746c88fb81be59db8b1a42ce4a38dc4a3bd/Dockerfile#L166
@Sebastian Nemeth it’s only needed for locally when doing native development
(e.g. docker compose)
chamber exec app -- docker-compose up
I agree though - the docs should be updated to make that clear.
you’re the second person in the last day to point that out.
Glad I’m helping
Problems with cold_start doco:
I’ll pin this here, and post fixes and small problems I find with the cold_start doco here…
This line under Provision iam Project to Create root IAM role…
“Update the TF_VAR_root_account_admin_user_names variable in Dockerfile for the root account with your own values.”
Doesn’t make sense… in root.cloudposse.co repo, the root account admin user names are no longer kept in the Dockerfile, they’re in the attached terraform templates (it seems)
@Sebastian Nemeth thanks. The docs show the older version, we updated the repos since then. We need to update the docs (will do it this week).
Cool, I’ll wait for the updates then. Will keep posting what I find in this thread…
you can open an issue for that in the docs. And all other problems you find. Thanks
Yea thanks, we see the open issues so we don’t forget to fix it
For now, you need to update the names not in the Dockerfile, but in the .tfvars files

hi, i am looking for strategy to use conf with local dev environment, the way i did the workaround is to manuall add dockerargs in wrapper as
--volume=$(pwd)/aws:/conf). So when i run it within the repo root, it mounts my conf to wrapper and i can do changes in my IDE and sync it directly from geodesic shell
so for local dev, i always
and work from there
the drawback is, I have to copy all standard modules to my repo, cause if I do COPY
--from=terraform-root-modules /aws/tfstate-backend/ /conf/tfstate-backend/ the root modules were hidden
$HOME <– host machine
yes that I am aware of
hrmm can you elaborate on what you want to achieve beyond IDE?
or why this is insufficieint with IDE.
actually you are right with this, it just being habitual I ended up using the default root
i just have too much nesting in my local so felt lazy about this
yea, that is a challenge - also with a lot of docker inheritance it’s not a universal solution for all kind of debugging.
i find it works really well with
but this still lacks 1 thing, not a major glitch, to work with root modules I have to switch to
~ but then to work with my modules I have to switch back to
can’t we force docker mount to show the content of container in the mount directory
yea, that would be nice. something that automatically drops you in the context of your IDE path
if you open terminal within ide, it drops you there only
basically, just need it to pass the
--workdir arg to docker
or do a
cd /.... upon entering the shell, perhaps with something in
i don’t have a idea right now on what the convention would look like
open to suggestions
perhaps caller can set a
I think I didn’t follow you completely
what would be advantage of
it would be placeholder for my localhost directory?
to rephrase the question, it would be nice to see in IDE what is coming up from root-modules
that way i have a collective view of what is my total infra, root+custom modules in one dir
GEODESIC_WORKDIR would be where you would get dropped in the geodeisc shell
it would be used only if present.
that would spare the caller the need to remember to
haha i just came across that tool the other day.
it’s useful for
go or say
c++ projects. it will watch a directory and call a make target anytime it changes.
not really applicable in this situation, but thought i’d share anyways
collective view of what is my total infra, root+custom modules in one dir
this is really asking for an overlay filesystem
i have seen fuse filesystems that will mimick this
but i think that would be HIGHLY experimental
I think @rohit.verma was asking about seeing the files coming from root-modules in the IDE. Basically on the host file system to see the files from the container. If you work with let’s say testing.cloudposse.co, now it’s completely empty in the IDE on the host, you can see the Terraform files only inside geodesic
ohhhh - i see
but in my case, I would do
then start the container, and it would drop me in that folder where I iterate.
Then in my IDE, I operate in

Thanks @Erik Osterman (Cloud Posse) that seems pretty straightforward I wilkl have a look at it when I achieve to deploy my kops cluster. ATM I could not install the staging env due to VPC conflicts
what kind of VPC conflicts?
Haven’t encountered that before.
Well I tried to run both kops-aws-platform and backing-services from the staging image and it complains on
module.kops_vpc_peering.module.kops_metadata.data.aws_vpc.kops: data.aws_vpc.kops: no matching VPC found
Aha, @Andriy Knysh (Cloud Posse) will tell you how to fix it
it comes down to a bad env setting for the cluster name
i think he’s working on a fix to docs for that.
i ran into this today
Hey guys, is there any way to re-use an existing AWS linked account to initialize testing, audit, staging and prod geomodules?

Yes you should be able to reuse them.
You can use ‘terraform import’ command with the resource name and account is to import state
Can we automate geodesic terraform to build and destroy a cluster in a CI env ?
@Yoann We have this on our roadmap for this quarter, but do not have any reference architectures for how to do it.
if you want to get a headstart on it, i can walk you through how we would approach it
a geodesic module is just a container. so if you run that container in a context which provides either the AWS credentials as environment variables (
AWS_SECRET_ACCESS_KEY) to the container or where there’s an AWS instance profile with sufficient access credentials, then you can just run the commands you would normally run inside the container
docker run --env-file /dev/shm/secrets.env --workdir /conf/myproject/ mycompany/staging.mycompany.com:1.2.3 chamber exec myproject -- terraform apply
that’s saying start a docker container with environment variables from a file called
change directory to
chamber exec myproject to get SSM secrets from
and then run
so you see, deploying infrastructure with CI/CD is not really much different than any deployment process, since it’s all bundled in a container.
I am afk so cannot really share any details easily, but you are correct. One geodesic module per AWS account. One delegated dns zone per account. The root account is responsible for delegating the zones, but first need to create the zones
If you look for account-dns that is where the sub account provisions a zone
If you look for root-dns that is where the delegation happens
@Sebastian Nemeth take a look https://docs.cloudposse.com/reference-architectures/
So for a cold start, there are a number steps that must be followed in order to get everything linked up.
Holy shit guys, it’s Saturday!
V. much appreciate your response on the weekend. Was not expecting that!
here are steps we perform to provision
dns on all accounts:
- In https://github.com/cloudposse/root.cloudposse.co, we fisrt provision the
parentzone (https://github.com/cloudposse/terraform-root-modules/blob/master/aws/root-dns/parent.tf) and the
root.cloudposse.co - Example Terraform Reference Architecture for Geodesic Module Parent (“Root”) Organization in AWS.
terraform-root-modules - Collection of Terraform root module invocations for provisioning reference architectures
Haha! We’re mostly around in some capacity. :)
- Then we provision all other accounts (
@Andriy Knysh (Cloud Posse) has provisioned this stack dozens of times
- Then we come back to
rootand provision Zone delegation (Name servers)
^ that’s a high level description to provision
dns on all accounts
more details are in the docs https://docs.cloudposse.com/reference-architectures/cold-start/
please ask more questions
Okay, so parent zone = company.com…? So then what’s root hosted zone for?
I mean, I get that each module has its own zone and the parent delegates to the modules… but then why a separate root hosted zone?
One more consideration I don’t know if we call out in our docs is you should have an infrastructure domain that is separate from your branded “vanity” domain
The infrastructure domains are for service discovery and should be canonical, while vanity domains how you expose services publicly.
what’s diff between parent and root?
good question @Sebastian Nemeth
[xxxxx.cloudposse.co](http://xxxxx.cloudposse.co) on all accounts so it’s mostly for:
- To have consistent naming
Yes, for root account not strictly required, but we do it for consistency. To date, we haven’t had to provision any sub domains off of the root account since all it handles is identity. But if for some reason we did need to, it would be on that sub domain.
- Parent zone
[company.com](http://company.com)is just DNS name, but we name our AWS accounts
so mostly to have the same naming on all accounts, and also the same naming on all AWS resources (e.g. roles
and AWS profiles
okay makes sense… so the logical hierarchy is…
for DNS yes
from the point of view of AWS organization:
so then, is there ever a use case for actually using root’s dns records?
thanks, we’ll add that, nice point
we have something like that in the docs, but agree, it’s not easy to follow unless we make big notes about that
