add postgres driver through helm chart

[adeel-ansari]

Hi,

I'm trying to use the SystemInitialization section of the doris helm chart to download the postgres driver. However, I'm running into errors. I'm trying something simple to troubleshoot:

systemInitialization: initImage: "selectdb/alpine:latest" command: ["/bin/sh", "-c", "echo hello"]

Even that is giving the following error:

Error: failed to create containerd task: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/bin/sh -c echo hello": stat /bin/sh -c echo hello: no such file or directory: unknown

Do you know where I may be going wrong? The full set of commands I need to perform are the following but I'm stuck at the moment:

    #       cd /opt/apache-doris && \
    #       mkdir -p be/jdbc_drivers && \
    #       curl -o be/jdbc_drivers/postgresql-42.5.6.jar https://jdbc.postgresql.org/download/postgresql-42.5.6.jar
