AWS CodeBuild项目卡在QUEUED阶段无法推进问题求助

I’ve run into nearly identical issues before, and here are some practical troubleshooting steps that helped me resolve it:

• Check CodeBuild Service Quotas
  The most common culprit is hitting the concurrent build limit for your AWS account. Head to the CodeBuild console, navigate to Settings > Quotas on the left sidebar, and verify if you’ve reached the maximum number of concurrent builds allowed. If so, you can either request a quota increase through AWS Support or pause non-urgent build tasks to free up capacity.

• Validate Build Project IAM Role Permissions
  Even if everything worked last week, it’s possible the IAM role associated with your CodeBuild project was accidentally modified. Ensure the role has essential permissions like codebuild:StartBuild, logs:CreateLogStream, logs:PutLogEvents, and access to your source code repository (e.g., S3, CodeCommit, GitHub). Also double-check the role’s trust policy to confirm it permits codebuild.amazonaws.com to assume the role.

• Inspect VPC Configuration (If Applicable)
  If your build project is configured to run within a VPC, network issues can cause it to get stuck in the queue. Verify that the subnet has a functional NAT gateway (for outbound internet access to AWS services), and that security groups allow outbound traffic to S3, CloudWatch, and your source repository. As a quick test, temporarily switch the project to run without a VPC—if it completes successfully, you’ve narrowed the problem down to VPC network configuration.

• Check AWS Regional Service Status
  Occasional service disruptions in your AWS region can halt CodeBuild operations. Visit the AWS Status Dashboard to check if there are any ongoing issues or outages for the CodeBuild service in your region. I once spent hours troubleshooting only to find out it was a temporary regional service glitch that resolved itself after a couple of hours.

• Test with a Minimal Build Project
  Create a simple, standalone CodeBuild project (e.g., a build spec that just runs echo "Hello World") and try starting it. If this minimal project also gets stuck in QUEUED, the issue is likely account-wide or region-specific. If it runs successfully, compare the configuration of this working project with your problematic ones to identify differences (like environment variables, source settings, or compute types).
