# aws-bills-on-slack
A monkey increases your visibility on AWS bills via Slack, running on AWS Lambda on a daily basis 🐒
## Prerequisites
- Slack Incoming Webhook
- An AWS account with AWS Organizations enabled
- `aws-bills-on-slack` uses [`toricls/acos`](https://github.com/toricls/acos) as its dependency so you may find more details about the prerequisites in the [`toricls/acos`'s prerequisites](https://github.com/toricls/acos/blob/main/README.md#prerequisites) to run.
## Installation
First clone this repository to your local machine or somewhere. You can use any tools whatever you want like AWS SAM, AWS CloudFormation, or Terraform, to deploy `aws-bills-on-slack` on AWS. See the following sections for more details.
### Install using AWS SAM (tested and recommended)
**For the first deployment:**
> **Note**
> You'll be prompted to enter some parameters after running the `sam deploy` command. See the [template.yaml's "Parameters" section](./deploy/aws-sam/template.yaml) for more info about the parameters.
```shell
cd /path/to/your/aws-bills-on-slack
sam build --template ./deploy/aws-sam/template.yaml
sam deploy --guided --stack-name aws-bills-on-slack --capabilities CAPABILITY_IAM # `--profile` and/or `--region` options may be also needed
```
_We'd strongly recommend you to set `./deploy/aws-sam/samconfig.toml` for the `SAM configuration file` parameter that is prompted by the `sam deploy` command. This will make your subsequent deployments much easier._
See full example output of `sam deploy`
```bash
$ sam deploy --guided --stack-name aws-bills-on-slack --capabilities CAPABILITY_IAM
Configuring SAM deploy
======================
Looking for config file [samconfig.toml] : Not found
Setting default arguments for 'sam deploy'
=========================================
Stack Name [aws-bills-on-slack]:
AWS Region [ap-northeast-1]:
Parameter MessageText [Here's the daily bill on our AWS accounts:]:
Parameter OuId []:
Parameter SlackIncomingWebhookUrl []:
Parameter CronScheduleString [cron(0 0 * * ? *)]: cron(0 0 * * ? *)
#Shows you resources changes to be deployed and require a 'Y' to initiate deploy
Confirm changes before deploy [y/N]: y
#SAM needs permission to be able to create roles to connect to the resources in your template
Allow SAM CLI IAM role creation [Y/n]: Y
#Preserves the state of previously provisioned resources when an operation fails
Disable rollback [y/N]: N
Save arguments to configuration file [Y/n]: Y
SAM configuration file [samconfig.toml]: ./deploy/aws-sam/samconfig.toml
SAM configuration environment [default]: default
Looking for resources needed for deployment:
Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-123456789012
A different default S3 bucket can be set in samconfig.toml and auto resolution of buckets turned off by setting resolve_s3=False
Saved arguments to config file
Running 'sam deploy' for future deployments will use the parameters saved above.
The above parameters can be changed by modifying samconfig.toml

**For subsequent deployments:**
You may want to re-deploy once you made some changes on the application code or the template.yaml file. In that case, you can use the following command to deploy the changes. Note that if you want to change the paremeters which you entered in the first deployment, you need to edit the `./deploy/aws-sam/samconfig.toml` file before running the `sam deploy` command.
```shell
cd /path/to/your/aws-bills-on-slack
# edit the code or the template.yaml file
sam build --template ./deploy/aws-sam/template.yaml
sam deploy --config-file ./deploy/aws-sam/samconfig.toml --no-confirm-changeset # `--profile` and/or `--region` options may be also needed
```
