Hello,
I did created a dropwizzard microservice as per the documentation in the
k8's cluster.
When I get into that k8's pod I see it runs as root user. Basically, I
did, whoami within that terminal. This is a security concern for our
production.
For this reason, I changed the as below;
DefaultServerFactory defaultServerFactory = (DefaultServerFactory)
getServerFactory();
defaultServerFactory.setStartsAsRoot(false);
With this I get;
ERROR [2020-03-10 06:29:59,267] io.dropwizard.cli.ServerCommand: Unable to
start server, shutting down
