`maqpna rollback`

Roll the Helm release back to an earlier revision

Operateplugin: maqpna-install-o json | yaml

Synopsis#

maqpna rollback [REVISION] [--wait] [--dry-run] [--force] [--release maqpna] [-n NS] [--timeout 10m]

Description#

REVISION defaults to the previous revision ('maqpna status' lists them). The CRDs are not rolled back. Rollback is refused when an installed CRD stores a version the target revision's chart does not define (the old operator could not read those objects); --force overrides.

Flags#

Flag	Type	Description	Default
`--debug`	switch	print Helm's debug log to stderr	none
`--dry-run`	switch	check and print the plan; change nothing	none
`--force`	switch	roll back even when CRD stored versions would be unknown to the target revision	none
`--kube-context`	string	kubeconfig context (default: the maqpna context's)	none
`-n`, `--namespace`	string	namespace of the MAQPNA control plane (the Helm release)	`maqpna-system`
`--release`	string	Helm release name	`maqpna`
`--timeout`	duration	timeout of Kubernetes operations (CRDs Established, `--wait`)	`10m0s`
`--wait`	switch	wait until every workload is ready	none

The global flags (--context, -o, --no-color, ...) work with every command.

Examples#

$ maqpna rollback --dry-run
$ maqpna rollback 3 --wait

What happens when you run it#

Runs the lifecycle plugin maqpna-install (next to maqpna or on PATH), which drives the Helm v3 SDK against the cluster of your kubeconfig (--kubeconfig, --kube-context).
--dry-run: check and print the plan; change nothing.
--force: roll back even when CRD stored versions would be unknown to the target revision.
--wait: wait until every workload is ready.
Prints a table by default; -o json or -o yaml print the data, and --jq EXPR filters the JSON.

Exit codes#

Code	Meaning
`0`	success
`1`	error (the message says what failed, with a hint when there is one)
`2`	usage error: unknown flag, missing argument or bad value; the synopsis is printed
`3`	a check failed, a change is blocked, or a result did not match (tamper, policy mismatch) (not used by this command)

Terminal demo#

maqpna rollback --help.cast

This command needs a Kubernetes cluster with MAQPNA installed, so the recording shows its help. Try it against a cluster from Install.
