How to Fetch your AWS Billing Info on Slack?
Have you ever wanted a simple way of displaying your AWS billing info on Slack? With Nimbella Commander, you can have your current bill or a bill from any other month displayed in one command to your Slack workspace. This conveniently integrated AWS billing functionality will allow developers to have cost-visibility without having to navigate complex billing systems, which will benefit the entire organization in the long run.
Later, I’ll show you how to restrict who can access this Slack command so it’s only available to people who need to know.
In just 7 simple steps, we will install Commander into Slack, add the API keys to Commander, and run the commands to show your AWS bill. If you don’t have any API keys set up in your AWS account, then you can scroll down to the section titled “Creating test API Keys for Commander”. But if you already have API Keys ready, then you can start at the section titled “Install Commander into Slack”.
Install Commander into Slack:
- Add Nimbella Commander to your Slack Team. You can add it by searching “Nimbella” in the apps tab on Slack. You can also add it by going to our official website and clicking the “Add to Slack” button.
- In order to get your AWS billing details, you’ll need to install the billing Command Set. Command Sets are a packaging specification for Slack commands, and a convenient way to share commands via GitHub or open source. Command Sets are installed into your Slack teams via the Nimbella Commander by typing the command /nc csm_install billing in your Slack prompt.
Applying your API Keys:
- Next, we need to bind some secrets to the billing commands. Specifically, the AWS API keys you generated earlier for the AWS API will be encrypted (outside of Slack) and attached to the slash command. To do this, type /nc secret_create to bring up the Nimbella Secret Creator. We’re creating the secrets outside of Slack so that Slack will only see encrypted strings and not your API keys. When you run the secrets command, you will see an output that looks like this:
- Click on the Secret Creator link to be redirected to the page which encrypts your API keys.
- Add your AWS keys to the fields in the Secret Creator as illustrated in the following figure. Next, click the “Make Secrets” button to generate the commands you’ll need to copy and paste into your Slack prompt.
- After clicking the “Make Secrets” button, the commands you’ll need to run on your Slack page will appear. Copy each command one at a time and paste them into Slack (using Clipboard copy). This will take your AWS Cost Explorer keys and apply them.
Run the billing Command Set in Slack:
- Finally, run the built-in command /dapp awsbill to see your AWS billing info.
- To see a particular month bill, try /dapp awsbill MM/YYYY
- You likely don’t want everyone in your Slack team to run this command. Nimbella Commander offers a neat feature to allow only certain users to run specific commands. For example, you can restrict access to the AWS billing command to specific users using** **/nc command_runners awsbill+ @user1 + @user2, substituting for “user1” and “user2” the Slack names of your teammates that should have access to the AWS billing details.
- It’s worth also mentioning that you have access to an audit trail to see who’s run your commands. This is useful for administrators and team oversight where appropriate. Type /nc command_log awsbill
- One last thing that’s important to know is that the code for the awsbill command you import into Commander is yours to edit. If you type /nc command_code awsbill, you will receive a secure link that will allow you to edit the command.
Using Nimbella’s access control you can also limit who can view and edit the code that implements a particular command as well. The built-in Secret Creator means your sensitive data remains outside of Slack and accessible only to the code you run. And with Audit Logs, you have accountability and historical data readily available at your fingertips. These are powerful features of the Commander that don’t exist in Slack otherwise. For more information about Commander, visit our website. We’d also love to hear from you via our community Slack channel or on GitHub.
