Description Direct Docs Feedback 2021-02-09 09:46:29 UTC

when adding a cell into a tls-everywhere environment also the cellcontroller internal api vip is required to be added to the central overcloud controllers because when using a tls-everywhere environment nova uses the cell controller internal api hostname instead of the vip to connect to the cell DB.

Comment 1 Martin Schuppert 2021-02-09 09:57:04 UTC

instead of:
CELL_INTERNALAPI_INFO=$(ssh heat-admin@${CELL_CTRL_IP} egrep cellcontrol.*\.internalapi /etc/hosts)

it should be:
CELL_INTERNALAPI_INFO=$(ssh heat-admin@${CELL_CTRL_IP} egrep cell1.*\.internalapi /etc/hosts)

Where cell1 is the prefix to identify only the cell systems and exclude the central controller systems.

Comment 3 Martin Schuppert 2021-02-10 07:40:24 UTC

We also have to replace in step 3 CELL_MYSQL_VIP to get either the IP or the endpoint hostname:

current:
(undercloud) [stack@undercloud ~]$ CELL_MYSQL_VIP=$(ssh heat-admin@${CELL_CTRL_IP} sudo \
                                    crudini --get /var/lib/config-data/nova/etc/nova/nova.conf database connection \
                                    | perl -nle'/(\d+\.\d+\.\d+\.\d+)/ && print $1')

should be:
(undercloud) [stack@undercloud ~]$ CELL_MYSQL_VIP=$(ssh heat-admin@${CELL_CTRL_IP} sudo \
                                    crudini --get /var/lib/config-data/nova/etc/nova/nova.conf database connection \
                                    | awk -F[@/] '{print $4}'
