Siema, mam kubernetesową zagwozdkę, z którą nie umiem sobie poradzić. Może ktoś ma wolną chwilę, żeby rzucić okiem i napisać, czego nie widzę (╯︵╰,)
Chciałbym postawić w statefulsecie bazę danych uruchomioną z obrazu mongo.
Ich dokumentacja (https://hub.docker.com/_/mongo) wskazuje następująco:
#v+
MONGO_INITDB_ROOT_USERNAME, MONGO_INITDB_ROOT_PASSWORD
These variables, used in conjunction, create a new user and set that user's password. This user is created in the admin authentication database and given the role of root, which is a "superuser" role.
#v-
Więc dodałem do definicji kontenera w yamlu takie zmienne:
#v+
containers:
- name: mongo
image: mongo
ports:
- containerPort: 27017
volumeMounts:
- name: database-storage
mountPath: /data/db
env:
- name: MONGO_INITDB_ROOT_USERNAME
value: admin
- name: MONGO_INITDB_ROOT_PASSWORD
value: pass
#v-
Po wywołaniu describe na uruchomionym podzie zmienne się pokazują:
#v+

@arghhh: Bazy danych w kubełkach to nie jest dobry pomysł.

Uruchomiłeś może to mongo wczesniej bez tych envów i dodałeś je dopiero później? Może być tak że trzeba wywalić volume żeby został stworzony na nowo
