Long provisioning times with amazonlinux-aarch64-standard:3.0 (ARM64) when triggered via GitLab webhook

[cardthp]

When running builds with Amazon Linux 2023 ARM64 standard images (aws/codebuild/amazonlinux-aarch64-standard:3.0), CodeBuild provisioning is consistently very slow.

Provisioning takes ~180–190 seconds before the build even starts.

Other phases (DOWNLOAD_SOURCE, INSTALL, PRE_BUILD) complete in under 1 second each.

I use GitLab webhook integration to trigger CodeBuild, so in GitLab CI this shows up as the job being “queued” for 3+ minutes, even though the delay is actually inside CodeBuild’s Provisioning step.

I tested every available version of the Amazon Linux 2023 ARM64 images (static tags, as well as latest).
All of them show the same 3-minute provisioning slowdown.

Note. My Codebuild is on ap-southeast-1 region

@subinataws Sorry to bother you — I saw your response about long provisioning times in a previous issue. I’m not sure if this is related to your team, but I would like to ask here since I’m experiencing similar delays.
