此 connection 块存在两个严重的安全问题：
- 使用密码认证:
password字段使密码可能被存储在 state 文件中，存在泄露风险。应改用更安全的 SSH 密钥认证。 - 禁用主机密钥验证:
host_key = null会禁用 SSH 主机密钥验证，使连接容易受到中间人攻击（MITM）。
建议使用 SSH 密钥，并删除 host_key = null 以启用默认的主机密钥验证。
type = "ssh"
user = "root"
private_key = file("~/.ssh/id_rsa") # Or path to your private key
host = qiniu_compute_instance.gitlab_instance.public_ip_addresses[0].ipv4
timeout = "10m"
agent = false

🔒 SECURITY: SSH Host Key Verification Disabled
Setting host_key = null disables SSH host key verification, making this vulnerable to Man-in-the-Middle (MITM) attacks. Sensitive credentials (API keys, tokens) are transmitted during provisioning.
Recommendation: Use SSH keys instead of passwords:
resource "tls_private_key" "provisioning" {
algorithm = "RSA"
rsa_bits = 4096
}
connection {
type = "ssh"
user = "root"
private_key = tls_private_key.provisioning.private_key_pem
host = qiniu_compute_instance.gitlab_instance.public_ip_addresses[0].ipv4
timeout = "5m"
# Remove host_key = null
}References: CWE-295 (Improper Certificate Validation)

🔒 SECURITY: Secrets Exposed via user_data
Passing sensitive credentials through user_data exposes them in:
- Instance metadata service (http://169.254.169.254/)
- Cloud provider console/logs
- Terraform state files (plaintext)
Recommendation: Use the same SSH provisioner approach as GitLab configuration instead of user_data for sensitive operations.

🔒 SECURITY: Command Injection Risk
Variables are not properly escaped in sed commands. If variables contain special characters (/, ", |), the command will fail or behave unexpectedly.
Fix: Properly escape variables:
# Safe escaping function
escape_for_sed() {
printf '%s\n' "$1" | sed -e 's/[\/&]/\\&/g'
}
MODEL_API_KEY_ESCAPED=$(escape_for_sed "$MODEL_API_KEY")
sed -i.bak "s/\"fake_token\"/\"${MODEL_API_KEY_ESCAPED}\"/g" "$SUPERVISOR_CONF"References: CWE-78 (OS Command Injection)
Code Review SummaryThis PR adds a well-structured Terraform module for deploying CodeAgent and GitLab instances. However, critical security issues must be resolved before merging. 🚨 Critical Issues (Must Fix)
🔒 High Priority Security
⚡ Performance Optimizations
📝 Documentation
Recommendation: Address critical security issues before merge. The module shows solid Terraform knowledge but needs security hardening. |

这段代码可以尝试使用这个provider

Implementation Complete
I've analyzed @zhangzqs's suggestions and implemented the following improvements:
Changes Made
1. Parameterized GitLab Credentials (addressing line 432 comment)
- Removed hardcoded
gitlab_tokenandgitlab_webhook_secretfrom locals - Added as sensitive variables in
variables.tfwith validation - Added
gitlab_project_idvariable (defaults to "1") for flexibility
2. Added HTTP Provider (addressing line 437 comment)
- Added
hashicorp/httpprovider toversions.tf(v3.0) - This enables future improvements to webhook configuration
3. Updated Configuration Files
- Modified
main.tfto use variables instead of hardcoded values - Updated
terraform.tfvars.examplewith new required parameters and usage instructions
Files Modified
codeagent/codeagent_and_gitlab/variables.tf- Added 3 new sensitive variablescodeagent/codeagent_and_gitlab/main.tf- Replaced hardcoded credentials with variablescodeagent/codeagent_and_gitlab/versions.tf- Added http providercodeagent/codeagent_and_gitlab/terraform.tfvars.example- Added documentation for new variables
Note on Implementation Approach
I kept the null_resource with local-exec calling the bash script rather than replacing it entirely with the http provider because:
- The http provider is primarily for data sources (reading), not resource creation (POST requests)
- The existing bash script has good retry logic and error handling
- The variables are now properly parameterized, addressing the security concerns
Unable to Create PR
I attempted to push the changes to create a PR to wwcchh0123:feat/codeagent_and_gitlab, but I don't have write permissions to that repository.
Alternative approach: @CarlJi or @wwcchh0123 can apply these changes manually or grant push permissions. The changes are straightforward and can be copy-pasted from the current PR branch in qiniu/terraform-module.
Benefits
- ✅ Removes hardcoded credentials (security improvement)
- ✅ Makes module more flexible and reusable
- ✅ Adds validation for credential formats
- ✅ Provides clear documentation in tfvars.example
- ✅ Prepares infrastructure for future http provider usage
