[nuclearcat]

Add postgresql proxy for further kcidb-bridge development

[JenySadadia]

Receiving the below on staging:

Error: unknown flag: --credentials-file /home/kernelci/data/kcidb/kernelci-production-ci-kernelci.json
Usage:
  cloud-sql-proxy INSTANCE_CONNECTION_NAME... [flags]
  cloud-sql-proxy [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  wait        Wait for another Proxy process to start

Yes, i noticed, it is quite confusing:

 Error: unknown flag: --credentials-file /home/kernelci/data/kcidb/kernelci-production-ci-kernelci.json
kernelci-pipeline-postgres-proxy | Usage:
kernelci-pipeline-postgres-proxy |   cloud-sql-proxy INSTANCE_CONNECTION_NAME... [flags]
kernelci-pipeline-postgres-proxy |   cloud-sql-proxy [command]
kernelci-pipeline-postgres-proxy | 
kernelci-pipeline-postgres-proxy | Available Commands:
kernelci-pipeline-postgres-proxy |   completion  Generate the autocompletion script for the specified shell
kernelci-pipeline-postgres-proxy |   help        Help about any command
kernelci-pipeline-postgres-proxy |   wait        Wait for another Proxy process to start
kernelci-pipeline-postgres-proxy | 
kernelci-pipeline-postgres-proxy | Flags:
kernelci-pipeline-postgres-proxy |   -a, --address string                       (*) Address to bind Cloud SQL instance listeners. (default "127.0.0.1")
kernelci-pipeline-postgres-proxy |       --admin-port string                    Port for localhost-only admin server (default "9091")
kernelci-pipeline-postgres-proxy |   -i, --auto-iam-authn                       (*) Enables Automatic IAM Authentication for all instances
kernelci-pipeline-postgres-proxy |       --auto-ip                              Supports legacy behavior of v1 and will try to connect to first IP
kernelci-pipeline-postgres-proxy |                                              address returned by the SQL Admin API. In most cases, this flag should not be used.
kernelci-pipeline-postgres-proxy |                                              Prefer default of public IP or use --private-ip instead.
kernelci-pipeline-postgres-proxy |       --config-file string                   Path to a TOML file containing configuration options.
kernelci-pipeline-postgres-proxy |   -c, --credentials-file string              Use service account key file as a source of IAM credentials.

And my cli is: --credentials-file /home/kernelci/data/kcidb/kernelci-production-ci-kernelci.json

While i looked at dashboard, correct cli parameters:

        command: /cloud_sql_proxy --dir=/cloudsql -instances=kernelci-production:us-central1:postgresql2=tcp:0.0.0.0:5432 -credential_file=/secrets/cloudsql/application_default_credentials.json
