While creating pod for postgres , pod going to error state

Kubernetes
#1

Hi ,

i am getting the error below .How can i handle it ?
I tried to execute voting-webapp on google cloud .Everything went fine except postgres pod is going to error state .
i checked logs .

satyam_saty143@cloudshell:~/K8s/example-voting-app-kub (innate-buckeye-276109)$ kubectl logs postgres-pod
Error: Database is uninitialized and superuser password is not specified.
You must specify POSTGRES_PASSWORD to a non-empty value for the
superuser. For example, “-e POSTGRES_PASSWORD=password” on “docker run”.

   You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
   connections without a password. This is *not* recommended.

   See PostgreSQL documentation about "trust":

please help how to fix it .

provide a password. can you share your yaml file here. Use configmap and pass it into deployment definition yaml file env section.

You have to pass the postgres_host_auth_method as an array item. This worked for me without having to use a deployment.
