mariadb fails to bootstrap in kolla-kubernetes

[Serguei Bezverkhi]

with latest master, mariah is failing to bootstrap in koala-kubernetes cluster. The issue is with the name of mysql pid file. When it is not forced in the command line, in kolla kubernetes it gets created in the form of mariadb-init-element-xqg3b.pid where mariadb-init-element-xqg3b is pod name. It creates a problem for bootstrap script is it checks for mysql.pid and as a result the script fails due to timeout. To solve this issue I suggest to pin pid name by using:
--pid-file=/var/lib/mysql/mariadb.pid
I have tested this solution and it works.

    Fixing mariadb bootstrap failure in kolla-kubernetes

    With latest master, mariadb is failing to bootstrap in kolla-kubernetes
    cluster. The issue is with the name of mysql pid file. When it is not forced
    in the command line, in kolla kubernetes it gets created in the form of
    mariadb-init-element-xqg4b.pid where mariadb-init-element-xqg3b is pod name,
    but bootstrap scripts explicitely checks for mysql.pid.
