Describe your issue

I followed the instruction for installing kubeflow pipeline on version 1.9.1
After creation of the namespaces and pods:

As you see some pods do not run.
And I think the main cause of the problem is that metadata-grpc-deployment cannot start working and it crashes with this error log:

WARNING: Logging before InitGoogleLogging() is written to STDERR
F1105 08:28:41.229691     1 metadata_store_server_main.cc:236] Check failed: absl::OkStatus() == status (OK vs. INTERNAL: mysql_real_connect failed: errno: , error:  [mysql-error-info='']) MetadataStore cannot be created with the given connection config.
*** Check failure stack trace: ***

I don't know why on earth it cannot connect to mysql!

Steps to reproduce the issue

Please try again with version 1.9.1 or the master branch and report back.

Please try again with version 1.9.1 or the master branch and report back.

I have already tried these several times.
Also deployed cert-manager but did not solve the problem

[juliusvonkohout]

Please follow the instructions and install according to the readme a full kubeflow platform on a kind cluster. If not I have to close or transfer the issue to Kubeflow/pipelines.

Is your pv and pvc bond correctly and whats your config of your sql pv?
