Comment Re: Docker is really about portability and scalabi (Score 1) 252

Right. A use case I have is my employer has a very old monolithic tomcat application, with about 3 or 4 different use-cases, and each one of these could be installed on a separate piece of hardware, optimize for that use-case's particular load and usage profile (in terms of hardware provisioning). In fact, there are cases where we provision a lot of RAM on the box, to handle large numbers of user sessions but the application is not very CPU intensive. But another part of this program is a job scheduler, which will periodically bring the whole system to its knees, even when we have a ton of CPU; and that makes the system unusable for the logged in users. The answer is to install it on two different machines, one with a ton of CPU, and the other with a ton of RAM. Now; doing that with Doocker is fairly trivial, as compared to provisionin two separate pieces of hardware.

I am a habitual rsyslog user anyway; but still for the life of me can't get rsyslog to work with journald. At least not with tomcat standard out logs.
. . . . yes, it would be nice if my devs would stop putting critical (and PHI) in std.out. . .
