Make logrotate a background process

[mamelara]

Background logrotate process

Description

Closes #22

This runs logrotate as a background process rather than in the
foreground. Degradation was caused by a delay in container startup when
catalina.out gets rotated. If the file is big enough, the delay can be
significant to cause degradation.

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration

• Other - add any additional tests here

Testing is done by doing the following:

stop any existing metacat containers/processes in the case of Spin run this using ess-dive-config:

./deploy.sh dev stop data-dev-ess-dive-lbl/app-metacat

then check if catalina.out is big enough on the community file system located on Cori:
ls -lah $CFS/m2690/ess-dive/metacat/usr/local/tomcat/logs/catalina.out

if it is less than 100M then make it bigger by using truncate:

truncate -s 200M catalina.out

Then restart the container using the built image with the commit number p57. So modify the docker-compose.yml file in ess-dive-config. You'll have to build the image and push to the spin registry using the essdive-appstack repository.

./deploy.sh dev up -d app-metacat

Then check for the following:

1. private packages are visible
2. new data can be submitted
3. catalina.out gets logrotated.

Note: You will have to delete one of the old tarballs if they already exist since logrotate will check for the existence of that tarball. If it already exists then no logrotation will happen.

Test Configuration

• Metacat Version: 2.12.3
• Python Version: 3.7.4
