Add the folowing enhancements to application updates during
Kubernetes upgrades:
1) Move the pre application update logic from kube-upgrade-start step
to a specific separated step called via a new command line option
named kube-pre-application-update, which can be triggered after the
download images step and before upgrading networking.
2) Move the post application update logic from kube-upgrade-complete
step to a specific separated step called via a new command line
option named kube-post-application-update, which can be triggered
after the kube-upgrade-complete stage and before the upgrade is
deleted.
3) Introduce validation logic to kube-upgrade-start step to check if
all applied apps have available versions compatible with intermediate
and target Kubernetes versions. Upgrades are blocked if apps marked
to be pre updated are incompatible with current and target Kubernetes
versions. Upgrades are also blocked if apps marked to be post updated
are incompatible with the target Kubernetes version.
4) Delete uploaded applications incompatible with the target Kubernetes
version and upload one that is compatible if available.
5) Restore kube-upgrade-start and kube-upgrade-complete to their
original logic before application updates during Kubernetes upgrades
was implemented on task 49416. The kube-upgrade-start step is
synchronous as it used to be before that change.
6) Update sysinv and cgts-client unit tests to account for the new
Kubernetes upgrade steps.
7) Create a helper function called "patch_kube_upgrade" to improve code
reuse when creating patch requests for new shell commands related to
Kubernetes upgrades.
Test Plan:
AIO-SX Test Cases:
PASS: Fresh install.
PASS: Successful Kubernetes single version upgrade with no apps that
need to be updated.
PASS: Successful Kubernetes multi-version upgrade with no apps that need
to be updated.
PASS: Successful Kubernetes upgrade with apps that need to be updated
before and after the new version is deployed.
PASS: Check if the upgrade is blocked if an app is incompatible with a
Kubernetes intermediate version during a multi-version
upgrade.
PASS: Check if the upgrade is blocked if an app marked to be pre updated
is incompatible with the Kubernetes target version.
PASS: Check if the upgrade is blocked if an app marked to be post
updated is incompatible with the Kubernetes target version.
PASS: Check if uploaded apps have been replaced by compatible versions.
PASS: Check if uploaded apps that do not have compatible versions were
removed.
PASS: Failure to run kube-pre-application-update and successful
retry.
PASS: Failure to run kube-post-application-update and successful
retry.
PASS: Abort during kube-pre-application-update and start over.
PASS: Reject aborting Kubernetes upgrade after post-updated-apps state.
AIO-DX Test Cases:
PASS: Fresh install.
PASS Successful Kubernetes upgrade with no apps that need to be
updated.
PASS: Successful Kubernetes upgrade with apps that need to be updated
before and after the new version is deployed.
PASS: Check if the upgrade is blocked if an app marked to be pre updated
is incompatible with the Kubernetes target version.
PASS: Check if the upgrade is blocked if an app marked to be post
updated is incompatible with the Kubernetes target version.
