Information request: How to connect to the database

[nvsajeeva]

Hello,
I have created a database with external access = false.
Please kindly let me know how I can access it.

k get db -A
NAMESPACE   NAME        SIZE   READY   STATUS   HOSTNAME                    AGE
everest     sajeevadb   2      2       ready    sajeevadb-haproxy.everest   16m

k get services -n everest

Hi @nvsajeeva, since you didn't enable external access, the provisioned DB is only accessible by clients living inside your k8s cluster.

Gathering connection info

In order to connect to it you'll need 2 things:

1. hostname or IP address
2. root user's password

You can easily get both of these from the UI but if you want to do it through the shell here's how:

1. kubectl get db <YourDBName> -n <YourDBNamespace> -o jsonpath='{.status.hostname}' But you already found this out, it's sajeevadb-haproxy.everest(10.99.180.88).
2. kubectl get secret everest-secrets-<YourDBName> -n <YourDBNamespace> -o go-template='{{.data.root|base64decode}}'

Connecting

For testing purposes, you can run a container with mysql tool and connect its console output to your terminal. In a real scenario, you'd configure your application instead. Here's how to test it:

1. Run the client application:

kubectl run -n everest -i --rm --tty percona-client --image=percona:8.0 --restart=Never -- bash -il

Executing it may require some time to deploy the corresponding Pod.

2. Now run the mysql tool in the percona-client command shell using the password obtained from the Secret instead of the placeholder.

mysql -h <YourDBHostname> -uroot -p'<RootPassword>'

This probably pertains to #914 .
