SBT plugin for validation of CloudFormation templates and operating AWS CloudFormations.

The plugin by default uses the default credential provider supplied by AWS SDK.

If you have already setup AWS CLI, you don't have to do any additional configurations.

Note that AWS_DEFAULT_REGION environment variable must also be set. For setting up AWS CLI, see the setup instructions.

In your plugins.sbt add:

resolvers += "SBT release"  at "https://dl.bintray.com/sbt/sbt-plugin-releases/"

addSbtPlugin("com.github.tptodorov" % "sbt-cloudformation" % "0.7.1")

In your build.sbt add:

// or any parameters required by your template
stackParams in Staging := Map("NumberWithRange" -> "2", "StringWithLength" -> "longstring")
// tag your stack
stackTags in Staging := Map("env" -> "staging", "app" -> "sample")

By default, there are two configurations: staging and production. For each configuration, the following settings are defined and used for task execution:

• stackTemplate - source of a CloudFormation template. By default, the first .template found in src/main/aws folder.
• stackParams - map of template parameters
• stackTags - map of tags assigned to new stacks
• stackRegion - region where the stack is created. By default, AWS_DEFAULT_REGION environment is used.
• stackName - name of the stack. By default, is in the form <artifactId>-<configuration>

For full list of settings, see Keys

• stackValidate validates CloudFormation *.template files. Supports ~ stackValidate command as well.
• stackCreate creates a stack. Does not block until create is complete
• stackUpdate updates a stack.
• stackDelete deletes a stack.
• stackDescribe describes a stack.
• stackStatus returns the current stack status
• stackWait blocks while the stack is in any of the PROGRESS states (see Usage below)

All tasks, except stackWait, return immediately.

• Template Validation - all *.template files in src/main/aws are validated during compilation. Continuous validation while you are developing your templates can be done by:

  sbt ~stackValidate

  You can also specify where your templates are:

  templatesSourceFolder <<= baseDirectory { _ / "src/main/resources" }

  Most of the time, it is useful to add the template validation as part of the compilation process:

  compile in Compile <<= (compile in Compile) dependsOn stackValidate

• Create/Update/Delete a stack and wait for it to complete.

  sbt " ; staging:stackCreate ; export staging:stackWait "

  sbt " ; staging:stackUpdate ; export staging:stackWait "

  sbt " ; staging:stackDelete ; export staging:stackWait "

Sample has a simple working setup.
