Hi, I have deployed a stein version openstack on server thought Kolla-ansible method. Then, I git clone the nova code, and ready to do coding in " nova/nova/conf/compute.py" However, many of nova containers include this file. So, I want to know that I should modify them all, or just pick a specific one. Thanks [root@chantyu kolla-ansible]# docker ps | grep nova 05f72e539974 kolla/centos-source-nova-compute:stein "dumb-init --single-…" 28 hours ago Up 2 hours nova_compute 7393a7d566ee kolla/centos-source-nova-libvirt:stein "dumb-init --single-…" 28 hours ago Up 5 hours nova_libvirt 9d8357cfa334 kolla/centos-source-nova-scheduler:stein "dumb-init --single-…" 32 hours ago Up 3 hours nova_scheduler 085b9da918df kolla/centos-source-nova-api:stein "dumb-init --single-…" 6 days ago Up 3 hours nova_api b80e9503e93e kolla/centos-source-nova-serialproxy:stein "dumb-init --single-…" 6 days ago Up 3 hours nova_serialproxy c15d41823a22 kolla/centos-source-nova-novncproxy:stein "dumb-init --single-…" 6 days ago Up 3 hours nova_novncproxy c30e47cd56c6 kolla/centos-source-nova-consoleauth:stein "dumb-init --single-…" 6 days ago Up 3 hours nova_consoleauth b7d5e9ba1f11 kolla/centos-source-nova-ssh:stein "dumb-init --single-…" 7 days ago Up 5 hours nova_ssh 3f81cd0a97ce kolla/centos-source-nova-conductor:stein "dumb-init --single-…" 7 days ago Up 3 hours nova_conductor [root@chantyu kolla-ansible]#
