What does this PR do?

We have a lot of "connection reset by peer" network errors that prevent install / upgrades. This PR adds it to the default go-containerregistry retry predicate so we can retry them up to 3 times.

Motivation

Less errors in the installer

Describe how to test/QA your changes

QA-ed manually. Only impacts the installer (not the agent)

Possible Drawbacks / Trade-offs

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

  • ✅ = significantly better comparison variant performance
  • ❌ = significantly worse comparison variant performance
  • ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

  1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

  2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

  3. Its configuration does not mark it "erratic".

CI Pass/Fail Decision

Failed. Some Quality Gates were violated.

  • quality_gate_idle_all_features, bounds check memory_usage: 8/10 replicas passed. Failed 2 which is > 0. Gate FAILED.
  • quality_gate_idle, bounds check memory_usage: 10/10 replicas passed. Gate passed.
