Currently in the "Microservices Architecture" ==> "Demo – Deploying voting app on Kubernetes" lesson I get the following in the logs when I try to create worker pod:

System.NotSupportedException: Authentication method not supported (Received: 10)
   at Npgsql.NpgsqlConnector.ParseServerMessage(ReadBuffer buf, BackendMessageCode code, Int32 len, DataRowLoadingMode dataRowLoadingMode, Boolean isPrependedMessage)
   at Npgsql.NpgsqlConnector.DoReadMessage(DataRowLoadingMode dataRowLoadingMode, Boolean isPrependedMessage)
   at Npgsql.NpgsqlConnector.ReadMessageWithPrepended(DataRowLoadingMode dataRowLoadingMode)
   at Npgsql.NpgsqlConnector.HandleAuthentication(String username, NpgsqlTimeout timeout)
   at Npgsql.NpgsqlConnector.Open(NpgsqlTimeout timeout)
   at Npgsql.ConnectorPool.Allocate(NpgsqlConnection conn, NpgsqlTimeout timeout)
   at Npgsql.NpgsqlConnection.OpenInternal()
   at Worker.Program.OpenDbConnection(String connectionString) in /code/src/Worker/Program.cs:line 78
   at Worker.Program.Main(String[] args) in /code/src/Worker/Program.cs:line 19

I presume this is related to needing to bump npgsql?

I wonder if this issue was resolved in [email protected] (npgsql/npgsql#1530)? But Im not sure, haven't delved in too much.

I tried to build an image locally to test but get:

Step 1/5 : FROM microsoft/dotnet:2.0.0-sdk
pull access denied for microsoft/dotnet, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

It seems like this is no longer available on Docker Hub?

I have the same error on google cloud.

The workaround for this issues is to change

example-voting-app/k8s-specifications/postgres-deploy.yaml

Line 24 in dd9247f

image: postgres

to image: postgres:9.4
