Pull Request Overview

This PR adds comprehensive usage examples for AWS Bedrock and Google Vertex AI integration to the Claude Code module documentation. The changes provide detailed configuration examples for both cloud platforms, enabling users to deploy Claude Code through their preferred cloud infrastructure instead of directly using Anthropic's API.

• Adds AWS Bedrock usage section with authentication options and prerequisites
• Adds Google Vertex AI usage section with GCP-specific configuration
• Updates all existing module version references from 3.0.0 to 3.0.1

had to bump again because of drive by fix on claude code. Can you reapprove @matifali @35C4n0r

[DevelopmentCats]

@matifali

Same deal. Ill merge this as soon as you approve. I cleaned up and updated all the versions since claude-code has had some other releases

[matifali]

I think this looks good to me. If you have tested this already. 🚢

Let me know what you think of this.

The Vertex config is a little messy, but that's the only way I was able to get it to authorize properly.

LGTM, but I think most users would want something per user using IAM roles or service accounts per workspace or per user.

LGTM, but I think most users would want something per user using IAM roles or service accounts per workspace or per user.

This is actually using the service accounts, but its not the most intuitive method

variable "vertex_sa_json" {
  type        = string
  description = "The complete JSON content of your Google Cloud service account key file. Create a service account in the GCP Console under 'IAM & Admin > Service Accounts', then create and download a JSON key. Copy the entire JSON content into this variable."
  sensitive   = true
}
