30s HealthStartInterval being applied to containers created with API 1.43 client #46733
Description
Description
If any non-zero health-start-period is provided to docker run, no health-cmd outcome will affect the container's health status (regardless of success or failure) until the first run after 30s has elapsed or the container is stopped/exits.
Reproduce
Case 1
--health-interval=2s--health-start-period=2s- container is "running" for 35s (
sleep 35) - EXPECTED: "healthy" after ~2-4s
- ACTUAL: "healthy" after ~30-32s
docker run --name=case-1 --health-cmd 'echo hello' --health-interval=2s --health-start-period=2s busybox sleep 35Case 2
--health-interval=2s--health-start-period=15s- container is "running" for 35s (
sleep 35) - EXPECTED: "healthy" after ~2-4s
- ACTUAL: "healthy" after 32s
docker run --name=case-2 --health-cmd 'echo hello' --health-interval=2s --health-start-period=15s busybox sleep 35Case 3
--health-interval=2s- container is "running" for 5s (
sleep 5) - EXPECTED: "healthy" after ~2s
- ACTUAL: "healthy" after ~2s (works as expected)
docker run --name=case-3 --health-cmd 'echo hello' --health-interval=2s busybox sleep 5Case 4
--health-interval=2s--health-start-period=15s- container is "running" for 20s (
sleep 20) - EXPECTED: "unhealthy" after ~15-17s
- ACTUAL: "unhealthy" w/o any health logs after 20s, so we don't know when or how the status changed.
- In this case, inspecting the container doesn't show any
logof healthcheck results, despite the fact that there should have been ~5s during which the container was running outside of thestart-period.- Extend the sleep command to
35and you will see that some healthcheck test outcomes are logged, but only after 30s (which is not what thestart-periodwas configured as).
- Extend the sleep command to
- I believe this case demonstrates that some 30s threshold is being respected as the
start-periodinstead of the user-provided value.
- In this case, inspecting the container doesn't show any
docker run --name=case-4 --health-cmd 'fake' --health-interval=2s --health-start-period=15s
busybox sleep 20Expected behavior
Based on the docs I expected:
- Any successful health command execution within a specified
start-periodto allow the container to be marked "healthy" (and any subsequent failure, even if within the start-period, would mark it as "unhealthy") - The first
health-cmdfailure result to occur after the specifiedstart-periodshould result in the container being immediately marked as unhealthy.
