Re: [kubernetes/kubernetes] `kubectl apply` removes all entries when attempting to remove a single duplicated entry in a persisted object (#58477)

[Kirill Kiyutin]

Is there a workaround for this that doesn't involve deleting the deployment?

Use edit, patch, or replace, instead of apply.

@kiyutink for me there was.

solution was to kubectl apply once more. Then it got all fixed and the env variable appeared back as defined in the manifest.

same issue with 1.20.6

kubectl version -o json
{
  "clientVersion": {
    "major": "1",
    "minor": "20",
    "gitVersion": "v1.20.6",
    "gitCommit": "8a62859e515889f07e3e3be6a1080413f17cf2c3",

Just happened to me on both 1.25 and 1.26
Duplicated configmap for which key and name were changed + duplication removed on same apply - the env var is completely absent after applying
ORIGINAL:

GENERAL_STATSD_HOST:   <set to the key 'host' of config map 'general.statsd'>    Optional: false
GENERAL_STATSD_HOST:   <set to the key 'host' of config map 'general.statsd'>    Optional: false

EXPECTED:

GENERAL_STATSD_HOST:   <set to the key 'yard.host' of config map 'general.statsd-k8s'>    Optional: false

ACTUAL

Resolved after re-applying
