# 10-minute deploy stability gate for setup-project skill.
|

|
|
# Polls pod readiness + HTTP 200 on target URL every 30s for 20 iterations.
|
||
|
|
# Requires 18/20 probes to succeed (tolerates 2 blips for restarts/DNS propagation).

|
# Usage:
|
||
|
|
# stability-gate.sh <namespace> <app-label> <url>

# Example:
|
||
|
|
# stability-gate.sh myapp myapp https://myapp.viktorbarzin.me
|

|
|
# Exit codes:
|
||
|
|
# 0 - Stable (>=18/20 probes OK)
|

|
|
# 1 - Unstable (<18/20 probes OK)
