BTW both infracost usage files have different settings for each environment for testing and demo purposes.

hey @glamorous-cat-93012, could you post your full pipeline yaml/configuration so that I can understand all the steps you’re using

Ok two follow-up questions: 1. Do you have this
infracost.yml
file checked into the main branch yet (or is it being introduced in this PR) 2. What is the output you’re getting on the PR, what projects is the
table
showing?

We did an ls -ltra on the directory to prove this ourselves and also attached the Pr comments.

mysterious-teacher-68276

10/14/2022, 9:34 AM
so the problem is this:
in your pipeline you specify
diff
&
breakdown
with
--path
rather than
--config-file

hmm this does look strange
i’m wondering if it’s getting an old artefact
what happens when you remove
Copy code
- publish: '$(Pipeline.Workspace)/s/$(Build.Repository.Name)/infracost-reports'
        displayName: 'Publish reports'
        artifact: drop
step
g

glamorous-cat-93012

10/14/2022, 9:52 AM
The publish step was just added at the end for us to be able to download the results, all it does is take the json files and publish them to a drop location so we can see them in the azdo dashboard.
Same results with or without this task
Another thing we noticed with InfraCost --path setting that does not make sense with config-file
m

mysterious-teacher-68276

10/14/2022, 9:53 AM
could you send me the
$(Pipeline.Workspace)/s/$(Build.Repository.Name)/infracost-reports/infracost.json
artefact in a private message
g

glamorous-cat-93012

10/14/2022, 9:55 AM
So when we use --path in the command like: infracost breakdown --path=$(Pipeline.Workspace)/s/$(Build.Repository.Name)/base/ \ infracost diff --path=$(Pipeline.Workspace)/s/$(Build.Repository.Name) \ You notice on break down we point to /base which in the temp main branch, then on diff we point to the current branch to we can compare both, right??
m

mysterious-teacher-68276

10/14/2022, 9:56 AM
yup
g

glamorous-cat-93012

10/14/2022, 9:56 AM
When you change to --config-file, there is no why to have two different paths for each branch so basically scans the same branch twice? --config-file $(Pipeline.Workspace)/s/$(Build.Repository.Name)/infracost.yml \
as the config file just has a field for --path and can't be changed between calls
m

mysterious-teacher-68276

10/14/2022, 9:57 AM
ah I think I see what’s going wrong with your yaml
g

glamorous-cat-93012

10/14/2022, 9:58 AM
The way we got around this was to switch working directories on the bash task, so we can use the config-file. workingDirectory: $(Pipeline.Workspace)/s/$(Build.Repository.Name)/base workingDirectory: $(Pipeline.Workspace)/s/$(Build.Repository.Name)
m

mysterious-teacher-68276

10/14/2022, 9:58 AM
yeah, that’s the correct way to do it

can you send me that infracost.json

sure

hmm @glamorous-cat-93012 this does look like a bug our side. It seems that we’re not populating the
past_resources
properly in for this case. I’ve managed to replicate your pr output locally - give me some time to figure out whats going on
g

glamorous-cat-93012

10/14/2022, 10:19 AM
Cool, no worries..
Also a great idea to update your doc to use workingDirectory when using --config-file as this caught us out for a while. workingDirectory: $(Pipeline.Workspace)/s/$(Build.Repository.Name)/base workingDirectory: $(Pipeline.Workspace)/s/$(Build.Repository.Name) 🙂

mysterious-teacher-68276

10/14/2022, 10:28 AM
hey @glamorous-cat-93012 so I think i’ve found the issue (which turns out not to be a bug but more a UX issue). With that PR are you introducing any cost changes?
g

glamorous-cat-93012

10/14/2022, 10:37 AM
In the usage file we have different settings for each env and we also updated the modules to use different ec2 instances so these should show the break down of nonp and prod?
and we do not see the different envs breakdown in the dashboard
message has been deleted
Strange, it's like it is not picking up the main resources at all from main.tf
only finding resources in the usage-file.yml
m

mysterious-teacher-68276

10/14/2022, 10:44 AM
It looks like it's not being able I pick up the usage file path
This fails silently so you wouldn't see this
Can I check that the path structure you've got is correct - where are you usage files in relation to the project
