        "Error running ['docker', 'run', '--name', 'nova_wait_for_db_sync', '--label', 'config_id=tripleo_step3', '--label', 'container_name=nova_wait_for_db_sync', '--label', 'managed_by=paunch', '--label', 'config_data={\"start_order\": 1, \"image\": \"172.16.0.1:8787/rhosp14/openstack-nova-placement-api:14.0-84\", \"command\": \"/docker-config-scripts/nova_wait_for_db_sync.py\", \"user\": \"root\", \"volumes\": [\"/var/lib/nova:/var/lib/nova:shared\", \"/var/lib/docker-config-scripts/:/docker-config-scripts/\", \"/var/lib/config-data/puppet-generated/nova_placement/etc/nova:/etc/nova:ro\"], \"net\": \"host\", \"detach\": false, \"privileged\": false}', '--net=host', '--privileged=false', '--user=root', '--volume=/var/lib/nova:/var/lib/nova:shared', '--volume=/var/lib/docker-config-scripts/:/docker-config-scripts/', '--volume=/var/lib/config-data/puppet-generated/nova_placement/etc/nova:/etc/nova:ro', '172.16.0.1:8787/rhosp14/openstack-nova-placement-api:14.0-84', '/docker-config-scripts/nova_wait_for_db_sync.py'].

Expected results:

Deployment succeeds


Additional info:

SSL-enabled cnf file is created correctly:

root@lab-controller01 my.cnf.d]# cat /var/lib/config-data/puppet-generated/nova_placement/etc/my.cnf.d/tripleo.cnf
[tripleo]
bind-address=172.17.1.201
ssl=1
ssl-ca=/etc/ipa/ca.crt

Connection built correctly:

connection=mysql+pymysql://nova_api:oGyhPvnh2PHyxURyHoBdtH9ES.redhat.local/nova_api?read_default_group=tripleo&read_default_file=/etc/my.cnf.d/tripleo.cnf

Non-secure logins fail as expected:

root@lab-controller01 my.cnf.d]# mysql -u nova_api -h 172.17.1.201 -p
Enter password:
ERROR 1045 (28000): Access denied for user 'nova_api'@'172.17.1.201' (using password: YES)

Secure logins using the cert work as expected:

[root@lab-controller01 my.cnf.d]# mysql -u nova_api -h 172.17.1.201 -p --ssl --ssl-ca=/etc/ipa/ca.crt
Enter password:

nova_wait_for_db_sync container doesn't mount cert but another using same image (int this case nova_api_db_sync) does:
