CCStar - CCTray proxy for AWS CodeBuild and CodePipeline

A project to allow CCTray, CCMenu, Nevergreen, and other compatible clients to read the status of projects in AWS CodeBuild and CodePipeline via the CCTray common format.

AWS Costs

CCStar runs in your AWS account, and therefore may incur costs, depending on whether it, and the rest of your account, fit in the AWS free tier.

CCStar uses the following cost-incurring resource types:

• DynamoDB
• API Gateway
• Lambda
• (Optionally) Secrets Manager

Note that in normal situations any costs incurred should be very small, or zero if in the free tier. But for accounts with many active projects and/or pipelines, or a large number of people making requests, there may be noteworthy costs. As in all things AWS, keep an eye on your costs.

Installation

CCStar is available as a SAR (Serverless Application Repository) application.

The easiest way to install CCStar is via the web console, but the best way is via CloudFormation, or other infrastructure-as-code. Whichever installation option you pick there are also configuration options, described later on in this README.

Installation via the web console

As a user with a good amount of privileges:

1. Go to CCStar in the SAR console, here, and adjust your region as necessary.
2. Press the Deploy button
3. Check you're ok with everything, then press the next Deploy button - This will deploy CCStar as a CloudFormation stack within your account.
4. Open up CloudFormation in the Web Console, find your installation of CCStar and wait for it to complete deploying.
5. Once it has completed deploying open the Outputs tab - you should see a CCTrayXMLURL output, and the value of this is the CCTray URL that you can use in CCMenu, etc.

Installation via infrastructure as code

This is a better way of managing CCStar over time, especially since it makes upgrading more simple.

If you use CloudFormation, you can include CCStar as an application within a parent stack. To add CCStar to a CloudFormation template, do the following:

• Make sure you have included the SAM transform in the file. You should see a line that reads Transform: AWS::Serverless-2016-10-31
• Add the following resource in your Resources section:

  CCStar:
    Type: AWS::Serverless::Application
    Properties:
      Location:
        ApplicationId: arn:aws:serverlessrepo:us-east-1:073101298092:applications/ccstar
        SemanticVersion: 0.2.8

• Optionally, add the following in your template's Outputs section:

  CCStarURL:
    Value: !GetAtt CCStar.Outputs.CCTrayXMLURL

• When deploying your script, make sure to use the CAPABILITY_AUTO_EXPAND capability, as well as CAPABILITY_IAM.

Then deploy your template. CCStar will appear as a nested stack within the deployed parent stack. Once deployment is complete, you should see the Output value if you added it, with the URL to use in CCMenu, etc.

Installation WITHOUT SAR

If you want to install without SAR then just download this source repo, and run the deploy.sh script. You may want to edit it a little for choosing a stack name.

Configuration

CCStar will install with zero configuration, in which case it will use defaults. However there are configuration options available, all of which can be provided as parameters to the SAR template:

Name	Default	Description
BasicAuthType	None	Type of Basic Auth to use - None, PlainTextSingleEntry, or GeneratedSecret (see more details below)
BasicAuthConfig	None	Configuration for Basic Auth, depends on value of BasicAuthType (see more details below)
APILocalCacheTTL	0	If greater than 0, number of seconds to cache generated API responses in the CCStar server. This may be useful for high volume installations to reduce costs since it will reduce the number of calls to DynamoDB. A typically useful value here may be 10.
LogLevel	Info	Debug, Info, Warn, or Error. Debug may log possibly secure details, like authorization headers, so use debug with caution.

As you can tell, the most significant configuration is for authentication / authorization. CCStar offers two types of auth - none at all, or HTTP Basic Auth (these are the two types of auth supported by CCMenu) . While Basic Auth may sound like a terrible idea, since all traffic with CCStar is over HTTPS then Basic Auth isn't actually a bad option.

If you don't want to use Basic Auth, just set BasicAuthType to None, the default.

If you do want to use Basic Auth, set BasicAuthType to one other options, as I describe next.

Using Basic Auth

Basic Auth relies on validating a user and password given by the browser. At the moment CCStar has two methods of configuration for a valid user and password.

The first option is passing in a user and password as a configuration parameter. To do this:

• Set BasicAuthType to PlainTextSingleEntry
• Set BasicAuthConfig to USERNAME:PASSWORD substituting USERNAME and PASSWORD for your values. Note that neither the username nor password can themselves contain a colon (':') due to CCStar's configuration parsing.

CloudFormation won't log the password, nor will it be visible in CloudFormation, since NoEcho is set to true in the CloudFormation template. However the password will be visible as plain text in the Lambda function configuration.

The second option is to use AWS Secrets Manager to generate and manage a user's password. To do this:

• Set BasicAuthType to GeneratedSecret
• Optionally, set BasicAuthConfig to be a username, or leave as None for the default. If you use the default , then the username will be CCStar

With GeneratedSecret, CCStar will create a secret in Secrets Manager named ${AWS::StackName }/BasicAuthSecret, where ${AWS::StackName} is the name of the stack that CCStar is deployed to. To find the password, navigate to this secret in the AWS Web Console and click on "Retrieve Secret Value".

If you're using GeneratedSecret the Secrets Manager Secret resource ARN is also provided as a CloudFormation Output named BasicAuthSecretArn.

NB: Secrets Manager is not free - it costs $0.40 per secret per month.

If neither of these basic auth configurations work for you please let me know by creating an issue, or by dropping me an email at [email protected], since I'm interested in what else people might need here.

Example using SAR

If you're using the infrastructure-as-code installation option described earlier, this is an example of how you would set some non-default configuration:

 CCStar:
   Type: AWS::Serverless::Application
   Properties:
     Location:
       ApplicationId: arn:aws:serverlessrepo:us-east-1:073101298092:applications/ccstar
       SemanticVersion: 0.2.8
     Parameters:
       BasicAuthType: GenerateSecret
       APILocalCacheTTL: 10

Usage

Once you've found the CCTray XML URL you should be able to use CCStar just like any other CCTray-compatible server.

Immediately after you install CCStar, however, you won't see any projects listed. CCStar keeps its own state of your projects and pipelines by listening for events. In other words before trying to connect to CCStar for the very first time after it's installed, kick off a project or pipeline to seed some data.

If you're not seeing any projects then check CCStar's DynamoDB table (you'll find it in the CloudFormation web console stack for CCStar) and see if it has any rows.

Upgrading CCStar

I plan to update CCStar with at least a couple more items. In order to upgrade your installation of CCStar via SAR installed via the web console (or CLI) see here .

If you installed SAR as a nested CloudFormation resource as described above in hte infrastructure-as-code section , you can simply change the SemanticVersion property and redeploy.
