12/30/2021, 4:05 PMHey guys.
I would like to publish my deployment outputs from CDK/SST into Slack, once the deployment finishes.
I can do this in many ways, but I was thinking to use SST somehow when the process finishes, and using the Slack API do publish the results.
Is the “script” construct designed to do this kind of things?
Thanks.

12/30/2021, 4:07 PMI would heavily suggest doing this outside Cloudformation. Things like handling errors will be impossible, and things like ensuring it runs every time will be difficult.

Adrián Mouly
12/30/2021, 4:07 PMYes, I agree with that.
Adrián Mouly
12/30/2021, 4:07 PMBut I know SST has the “script” concept.
Adrián Mouly
12/30/2021, 4:07 PMI thought you can execute things outside CF.

Derek Kershner
12/30/2021, 4:07 PMGithub actions or any other CI tool will handle this trivially and likely already has something built.

Adrián Mouly
12/30/2021, 4:08 PMYeah, I’m using bitbucket pipelines, I was trying to avoid having more stuff there.
Adrián Mouly
12/30/2021, 4:08 PMAnd put them in my infrastructure code.
Adrián Mouly
12/30/2021, 4:08 PMI was looking to use this:

Adrián Mouly
12/30/2021, 4:09 PMBut looks like it uses a Lambda.
Adrián Mouly
12/30/2021, 4:09 PMI already have Lambda integrations with Slack API.

12/30/2021, 4:10 PM@thdxr do you think my use-case would make sense for Script?
Adrián Mouly
12/30/2021, 4:10 PMMakes sense @Derek Kershner.
t
thdxr
12/30/2021, 4:10 PMyeah I think that makes sense
a
Adrián Mouly
12/30/2021, 4:11 PMI’m able to create scripts for different stages or the deployment?
Adrián Mouly
12/30/2021, 4:11 PMMaybe I want to send a notification when the process starts, and when it ends?
t
thdxr
12/30/2021, 4:11 PMyeah you can conditionally create the resources and passin the values you need forwarded to slack
a
Adrián Mouly
12/30/2021, 4:11 PMOk going to check.
Adrián Mouly
12/30/2021, 4:11 PMAlso what I like about this, is that I can re-use my Slack logic already existing in other lambdas.
Adrián Mouly
12/30/2021, 4:12 PMSomething I like is I can decouple my logic away from the CI/CD provider.
Adrián Mouly
12/30/2021, 4:12 PM@Derek Kershner that was my initial intention, reusing + decoupling from Bitbucket.

Derek Kershner
12/30/2021, 4:14 PMjust use the lack of a second message as indication of error?
a
Adrián Mouly
12/30/2021, 4:17 PMMmmm.
Adrián Mouly
12/30/2021, 4:17 PMGood point.
Adrián Mouly
12/30/2021, 4:17 PMI would need to handle reporting issues with the infrastructure code too.
d
Derek Kershner
12/30/2021, 4:17 PMIf you have backend logic you'd like to use during the CI process, id just set up a tiny API.
a
Adrián Mouly
12/30/2021, 4:18 PMYeah that could be too.
d
Derek Kershner
12/30/2021, 4:18 PMlike, if you need logic to decide the webhook url or something
a
Adrián Mouly
12/30/2021, 4:18 PMYeah, could be too.
Adrián Mouly
12/30/2021, 4:18 PMMain goal was to reduce logic from the ci/cd.
Adrián Mouly
12/30/2021, 4:19 PMAnd putting it into the Infra code… but well, that can also fail.
d
Derek Kershner
12/30/2021, 4:22 PMif this is your goal, you can just make a route that takes information and does everything needed for the CI/CD, but I would encourage you to think about why you are avoiding using CI/CD for its intended purpose as well. I have not used BitBucket, but something like github actions (and seed) can be controlled from code, similarly to the CDK, and would therefore achieve most benefits as well.

12/30/2021, 4:22 PMjust advice though, of course, you know your constraints better than us.
