Archives are gzipped and uploaded in parts of at most 90 MB with per-part
digests (edge request limit); pip installs ignore the task venv so transitive
dependencies land in products; the verifier sets NODE_PATH and the Java
classpath from products when starting the app.

kube-ax operator constraints

Verified by the operator on 2026-10-05. These constraints apply across all workloads.

  • Two workers, one task per worker, at most two tasks in flight cluster-wide. AX has no queue: a third apply returns no free workers available. Treat this as back-pressure, retry the same task/lane with 15–30 seconds of jitter until its deadline, and never count it as a sandbox failure or trigger VM fallback. The host dispatcher shares a two-slot reservation across workload instances and long-lived search executors.
  • / and /tmp are RAM-backed and consume the worker's 3 GiB. /workspace is the only disk-backed path, with about 2 GiB usable per task. Executor and verifier entrypoints use /workspace/tmp, /workspace/.npm, /workspace/.m2, /workspace/.composer, /workspace/.pip, and /workspace/.gradle through the respective tool environment variables. Builds and extracted checkouts live under /workspace too. The default aggregate workspace scratch guard is 2 GiB; OUSAST_SCRATCH_BYTES configures it. Exceeding it returns could_not_build, reason scratch limit. The guard polls during child execution and checks after exit; it is not an instantaneous filesystem quota or a replacement for the worker memory limit.
  • ousast-engine-search-verify-* tasks have no egress. The requested exception for files.because-security.com:443 is pending, not operationally verified. They receive a presigned manifest for a gzip level-6 archive containing checkout/, products/, and spec.json, built/exported by an executor. Compressed archives retain the 1 GiB cap and travel in parts of at most 90 MB, each digest-checked before assembly and extraction under /workspace. Only VERIFY_INPUT_URL and RESULT_URL cross the verifier boundary. Verifiers reject build recipes and do not install dependencies or fetch repositories. Executors finish and release their slots before verifier repetitions start. Both task types must be provisioned without model credentials.
  • All tasks share one public IP. Repository acquisition uses HTTPS git clone from github.com or archives from codeload.github.com, never api.github.com. Host-side metadata queries are a separate concern. Search tasks receive checkout archives; executor tool guidance carries the same acquisition rule. Retain the 60-second first-download retry for delayed task egress policy activation.
