Add --wsrep-provider=none to the mysql_bootstrap container
Depending on the version of mariadb/galera installed the mysql_bootstrap
command might fail. With the following unrevealing error:
openstack-mariadb-docker:2017-08-28.10 "bash -ec 'if [ -e /v" 3 hours ago Exited (124) 3 hours ago
The timeout is actually due to the fact that the following snippets does
not complete within 60 seconds:
"""
if [ -e /var/lib/mysql/mysql ]; then exit 0; fi
kolla_start
mysqld_safe --skip-networking --wsrep-on=OFF &
timeout ${DB_MAX_TIMEOUT} /bin/bash -c ''until mysqladmin -uroot -p"${DB_ROOT_PASSWORD}" ping 2>/dev/null; do sleep 1; done''
mysql -uroot -p"${DB_ROOT_PASSWORD}" -e "CREATE USER ''clustercheck''@''localhost'' IDENTIFIED BY '${DB_CLUSTERCHECK_PASSWORD}'';"
mysql -uroot -p"${DB_ROOT_PASSWORD}" -e "GRANT PROCESS ON *.* TO ''clustercheck'
"""
The problem is that with older mariadb versions:
galera-25.3.16-3.el7ost.x86_64
mariadb-5.5.56-2.el7.x86_64
The mysqld_safe process starts in galera mode (as opposed as to single
local mode):
170830 17:03:05 [Note] WSREP: Start replication
170830 17:03:05 [Note] WSREP: GMCast version 0
...
170830 17:03:05 [ERROR] WSREP: wsrep::connect() failed: 7
170830 17:03:05 [ERROR] Aborting
That means that even though we specified --wsrep-on=OFF it is still
starting in cluster mode. Let's add the extra --wsrep-provider=none
which older versions required.
Let's also add a '-x' to this transient container as that
would have helped a bit because we would have understood right away
that it was mysqld_safe that was not starting. I tested this
successfully on an environment that showed the problem. The new
option is still accepted by newer DB versions in any case.
